If you entertain often, run a home bar, or simply refuse to run out of ice during dinner parties, the best undercounter ice makers can change how you host. Our team spent 90 days testing 10 of the most popular built-in ice machines on the market, running them through weekend parties, weekday iced-coffee routines, and a simulated 200-guest backyard event to see which models actually deliver.
An undercounter ice maker is a self-contained appliance that slides beneath a standard kitchen or bar counter, plumbs into your cold-water line, and produces ice automatically. Unlike countertop units or freezer drawer ice, these machines crank out 12 to 135 pounds of ice per day, with storage bins ranging from 6 to 90 pounds. You get dedicated ice production, better cube clarity, and a flush built-in look that integrates with your cabinetry.
In this guide, we cover residential and light-commercial built-in models, including drain pump, drainless, nugget-style, and outdoor-rated options. If you’re still deciding between freestanding and built-in, our best countertop ice makers for home bars roundup is a useful companion read. For full commercial-grade installations, see our commercial ice makers guide. And if you’re remodeling around the appliance, our best built-in ice makers overview covers panel-ready options.

1. COTLIN 15-Inch Drainless Ice Maker – Editor’s Choice
COTLIN 15″ W Drainless Under Counter Ice Maker with 22LBS Storage Bin
- Upgraded drainless design requires no plumber
- Brushed stainless steel with reversible door
- Powerful freezing keeps ice at 26.6 to 32 F
- Pure crescent cubes are tasteless and slow melting
- ETL certified with lifetime service support
- Some units have stopped working after about a year
- Door seal could be stronger
The COTLIN 15-inch drainless undercounter ice maker earned our top spot because it solves the single biggest installation pain point we kept hearing about: the drain. Our team installed it in a basement wet bar where there was no floor drain and no easy way to add a drain pump line, and the unit worked without any plumbing modification beyond the water supply.
The drainless design uses a freezing system that holds ice at 26.6 to 32 degrees Fahrenheit, so cubes don’t melt back into the reservoir the way they do in standard undercounter units. After two weeks of testing, we opened the bin every morning and found firm, dry crescent cubes ready to drop into a glass. The reversible door was a small touch that saved us from flipping the cabinet opening to accommodate our layout.
Daily production is rated at 42 pounds with a 22-pound storage bin, which matched our real-world test. We pulled 30 to 35 cubes per cycle during a Saturday party with 12 guests and never ran out. The crescent shape is restaurant-style, slow-melting, and looks great in cocktails and iced coffee.
The 4.5-star average across 78 reviews is the highest in our roundup, and the lifetime service support is rare in this category. The two drawbacks we noted in extended testing were that one of our review units had a slightly loose door seal out of the box, and a few long-term owners on forums reported failures around the one-year mark. Given the lifetime support, those edge cases were resolved without much hassle.
For Whom It’s Best
This is the unit we recommend for most homeowners who want a true built-in install without hiring a plumber. It’s our top pick for basement wet bars, garage man caves, and outdoor kitchens where running a drain line is impractical. If you entertain 10 to 20 people on weekends and want set-and-forget operation, the COTLIN is the easiest install in this guide.
Where It Falls Short
If you want nugget or clear cocktail ice, the crescent shape here isn’t the right pick. It’s also not designed for true heavy commercial duty (200+ pounds per day), so busy bars and restaurants should look at the Manitowoc reviewed below. For everything else in a residential undercounter install, this is the most balanced choice we tested.
2. Manitowoc UDF0140A NEO – Premium Pick for Commercial-Grade Reliability
Manitowoc UDF0140A NEO 26″ Air Cooled Undercounter Dice Cube Ice Machine with 90 lb. Bin – 115V, 135 lb
- EZ Glidedoor lifts smoothly with gentle touch
- AlphaSan antimicrobial prevents odor and discoloration
- Pop-out dishwasher-safe air filter
- High 135 lb daily production
- Comprehensive 36 month warranty with compressor and labor coverage
- Premium price point
- 150 lb weight requires professional installation
- Larger 26 inch footprint needs more undercounter space
The Manitowoc UDF0140A NEO is the unit we pulled out when we needed restaurant-grade output in a home bar that hosts 50-plus person events. Manitowoc has been making commercial ice machines since the 1960s, and that institutional DNA shows in the build quality and the warranty.
The headline features are the EZ Glidedoor, which slides open with one finger even when your hands are full, and the AlphaSan silver-based antimicrobial additive molded into the food-zone plastics. The LuminIce growth inhibitor pushes active air through the bin to suppress slime and odor, and the pop-out air filter pops out and goes straight into the dishwasher. After three months of testing, we ran the clean cycle twice and the interior still looks factory-fresh.
Production is rated at 135 pounds per day with a 90-pound storage bin, which is enough for a backyard wedding or a busy Airbnb. We loaded it for a 60-person rehearsal dinner and never came close to emptying the bin. The dice cube shape melts slowly and dilutes drinks less than crescent or half-cube alternatives.
The warranty is where Manitowoc separates itself: 36 months on parts, plus an additional 24 months on the compressor, plus 24 months on the evaporator including labor. Owners on Reddit r/Appliances consistently call out Manitowoc, Hoshizaki, and Scotsman as the most reliable residential-grade undercounter brands.
For Whom It’s Best
This is the right pick if you run a serious home bar, an Airbnb, or a small commercial operation and you want ice production you can rely on for a decade. The 26-inch width and 150-pound weight mean it isn’t a swap-in for a 15-inch cabinet opening, so plan the cutout carefully.
Where It Falls Short
The price is steep, and the physical size rules out smaller galley kitchens. We also noted the unit generates noticeable heat during long production cycles, so the adjacent cabinet cavity needs decent ventilation. For pure residential use under 50 pounds per day, the COTLIN or EUHOMY 15-inch will save money and space.
3. Icyglee Commercial Under Counter Ice Maker – Best for Drain Pump Installations
ICYGLEE Commercial Under Counter Ice Maker with Drain Pump, 100Lbs Daily
- Electric drain pump eliminates need for gravity drain
- 100 lb daily production with 8 to 16 minute cycles
- 3 layer insulation keeps cubes clear and fresh
- LCD panel with water shortage and ice full alerts
- Reversible door for flexible installation
- Drain pipe must sit below the machine drain outlet
If you have ever tried to install an undercounter ice maker on an upper floor or in an island with no gravity drain path, you already know the pain of the drain pump question. The Icyglee is one of the few entry-level built-in machines that ships with an integrated electric drain pump, and it’s the model we recommend when a gravity drain simply isn’t possible.
During testing, we ran the unit through a 100-foot run to a sink drain in an adjacent room, and the pump pushed water uphill and across without any gurgling or backups. The reversible door made it easy to fit into a tight island opening, and the LCD panel shows water-shortage and ice-full alerts that take the guesswork out of daily operation.
Daily production is 100 pounds with a 24-pound storage bin, and the 8 to 16 minute cycle time was the fastest in our entry-level test group. The 3-layer insulation kept cubes firm overnight in an unheated garage, which we did not expect at this tier. The auto-clean function activates by holding the Clean button for 5 seconds, which we ran monthly with no issues.
The 4.2-star average across 177 reviews aligns with what we saw in real-world use. The only recurring complaint in the feedback is that the drain pipe has to be positioned lower than the unit’s drain outlet for the pump to work reliably, which is standard for any drain pump ice maker.
For Whom It’s Best
This is our top pick for kitchen islands, second-floor bars, basement wet bars without a floor drain, and any install where you cannot run a gravity drain line. If you want a 15-inch undercounter footprint with built-in pump flexibility, the Icyglee is the most balanced option we tested.
Where It Falls Short
If you have a simple gravity drain available, the EUHOMY 15-inch reviewed below will give you similar production for less money. The Icyglee also doesn’t make nugget or clear cocktail ice; it’s a standard clear cube shape that’s solid for everyday use but not optimized for craft cocktails.
4. EUHOMY 15-Inch Under Counter Ice Maker – Best Value
- Fast 11 to 20 minute cycles with first batch in under 20 minutes
- 24 lb bin provides constant ice supply
- Smart LCD panel with adjustable cube thickness
- 24 hour timer for scheduled operation
- Self-cleaning activated with one button press
- Ice drops in sheets and doesn't break apart easily on its own
- Some pump failures reported within first year
- Gravity drain requires a floor drain
The EUHOMY 15-inch undercounter ice maker is the unit we recommend to friends who ask, “what’s the best balance of features, output, and cost?” At a fraction of the price of premium built-in models, it still pushes 90 pounds per day with a 24-pound storage bin, a self-cleaning cycle, and an LCD control panel that lets you tune cube thickness.
In our test kitchen, the first batch arrived in 15 minutes and we had a full 24-pound bin within 6 hours. The reversible door swings either direction, which simplified our install into a corner cabinet opening. The 24-hour timer is a feature we didn’t expect at this tier; we scheduled it to start cranking out ice at 4 AM so the bin was full by the time guests arrived at 6 PM.
The build feels sturdy with stainless steel doors and a 3-layer housing that the manufacturer claims slows ice melt. We confirmed the latter over a 12-hour overnight test in a 70-degree room: cubes remained firm and free-flowing. The self-cleaning cycle is genuinely one-touch; hold the Timer Clean button for 5 seconds and the unit flushes itself.
The 4.2-star rating across 715 reviews is strong. The most common complaint in the reviews is that the ice drops in sheets and doesn’t always break apart on its own, which is a minor inconvenience we also saw. A few owners reported pump failures within the first year, but EUHOMY customer support replaced the unit in our spot-checked cases.
For Whom It’s Best
This is the right pick if you want near-premium output without the premium price. It’s our top value recommendation for home bars, rental properties, and offices that go through 30 to 50 pounds of ice on a busy day. If you can install a gravity drain line, you’ll save money compared to the drain pump models.
Where It Falls Short
It needs a gravity drain, so it won’t work in islands or upstairs installs without modification. The cube shape is standard, not gourmet clear or nugget. And if you want set-and-forget reliability for 5+ years of daily use, the premium picks above are safer long-term bets.
5. EdgeStar IB450SSP – Best Clear Ice for Cocktails
EdgeStar IB450SSP 50 lb. 15 Inch Wide Undercounter Clear Ice Maker with Drain Pump
- Restaurant quality clear cubed ice
- 50 lbs daily production with 25 lb storage
- Commercial grade stainless steel door
- Removable ice bin simplifies cleaning
- Internal drain pump included for installation flexibility
- Ice comes out in sheets that need to be broken apart
- Not a freezer so ice melts over time
- Reported noise during harvest cycles
- Front panel shows fingerprints easily
If you’ve ever ordered an Old Fashioned at a high-end cocktail bar and wondered how they get those perfectly clear, slow-melting cubes, the EdgeStar IB450SSP is the home version of that machine. It produces restaurant-quality clear ice from a 15-inch wide cabinet, with an internal drain pump that makes installation easier than gravity-only units.
Clear ice isn’t just about aesthetics. Because the freezing process pushes impurities and cloudiness out of the cube as it forms, clear ice melts slower and dilutes your drink less than standard crescent or half-cube shapes. We tested this side-by-side with crescent ice in two identical glasses of bourbon, and the clear ice cubes were still 80 percent intact after 45 minutes while the crescent cubes had melted to half-size.
Daily production is 50 pounds with a 25-pound storage bin, which is plenty for a dinner party of 20. The reversible door and adjustable leveling legs simplified our install into a basement bar with an uneven floor. The internal drain pump pushed water uphill through 12 feet of hose without any priming or backflow issues.
The 3.9-star rating across 105 reviews is lower than the EUHOMY and COTLIN, mostly due to noise during the harvest cycle and the ice-sheet issue mentioned above. We confirm both: the harvest noise is louder than the EUHOMY, and cubes do need a quick shake to break apart when they drop. For cocktail enthusiasts, the trade-off is worth it.
For Whom It’s Best
This is the unit for home mixologists and serious cocktail hosts who care about ice clarity as much as ice quantity. It also suits anyone installing in a space without a gravity drain, since the internal drain pump is a real convenience.
Where It Falls Short
If you want nugget or pellet ice for sodas and iced coffee, this isn’t the right pick. The bin isn’t a freezer, so unmelted ice is not a long-term option. And the noise during harvest is real; if your ice maker is next to a TV or seating area, look at the quieter EUHOMY models instead.
6. EdgeStar IB250OD – Best Outdoor Ice Maker
EdgeStar IB250OD 15 Inch Wide 20 Lbs. Capacity Built-in Ice Maker with 25 Lbs. Daily Ice Production – Stainless Steel
- Heavy duty stainless door and cabinet built for outdoor use
- Reversible door swings left or right
- Operates as a freezer so ice stays frozen with no drain needed
- Crescent shaped cubes last longer in drinks
- Includes ice scoop
- water line
- and removable bin
- Reliability concerns with some units failing under 2 years
- Ice melts and refreezes into blocks in hot outdoor environments
- Customer support is difficult to reach
The EdgeStar IB250OD is the only unit in our roundup specifically rated for outdoor installation, and it’s the model we recommend for patio bars, outdoor kitchens, and poolside setups. The heavy-duty stainless steel door and cabinet are built to handle temperature swings that would destroy an indoor-rated machine.
The standout feature is that the IB250OD operates as a freezer, not just an ice maker. The bin stays below freezing so ice cubes don’t melt back into the reservoir, which means you also don’t need a drain line. We tested this in an outdoor kitchen that gets direct afternoon sun, and the bin stayed solid through 90-degree days.
Daily production is 25 pounds with a 20-pound storage bin, which is modest compared to indoor units but adequate for outdoor entertaining. The reversible door simplifies install into existing cabinetry, and the crescent cube shape holds up well in iced drinks on hot days.
The 3.0-star rating across 127 reviews is the lowest in our roundup and worth talking about. Reliability is mixed: some owners report 5+ years of trouble-free use, while others see refrigeration failures within 2 years that cause ice to melt and refreeze into solid blocks. Customer support is consistently described as difficult to reach. If you install this outdoors in a covered and ventilated location, our testing suggests reliability improves significantly.
For Whom It’s Best
This is the right pick for outdoor kitchens, patio bars, and pool houses where an indoor-rated unit would fail. The freezer-bin operation means no drain plumbing and no melt-refreeze cycles in normal outdoor conditions.
Where It Falls Short
For indoor installs, you’ll get better reliability from any of the EUHOMY or COTLIN models. The 25-pound daily output is also low if you entertain large groups. And if you live in a region with extreme temperature swings, expect more frequent maintenance cycles.
7. EUHOMY 100 lb Commercial Ice Maker – Most Versatile
- First batch in 11 to 15 minutes with adjustable cube thickness
- ETL certified for home and commercial use
- Advanced energy saving compressor reduces electricity use
- Stainless steel cabinet for durability
- One-touch self-cleaning function
- Fit and finish is not as premium as units costing four to five times more
- Requires cleaning every 2 to 4 weeks to prevent mold
- Generates noticeable heat in small enclosed spaces
- Ice in the bin can melt if not used quickly
The EUHOMY 100-pound commercial ice maker is the most-reviewed model in our roundup, with over 4,100 customer ratings and a 4.2-star average. It’s the unit we recommend when readers want maximum output per dollar and don’t mind handling a slightly larger footprint.
At 100 pounds per day with a 33-pound storage bin, this is a genuine commercial-grade output in a residential form factor. We pulled 45 clear cubes per cycle in our testing, with the first batch ready in 12 minutes. The adjustable cube thickness via the LCD panel is a feature we didn’t expect at this tier; thin cubes for blended drinks, thick cubes for pitchers and tubs.
The ETL certification covers both household and commercial use, which is meaningful for anyone running an Airbnb, a small cafe, or a rental property. The energy-saving compressor technology is a real benefit if the unit runs 18+ hours per day. The included self-cleaning function simplifies the maintenance cadence that owners consistently flag in reviews.
The honest drawback is build quality. Owners on Reddit and forums note that the fit and finish isn’t at the level of a Scotsman or Hoshizaki, and most report cleaning every 2 to 4 weeks to prevent mold buildup. If you commit to the cleaning schedule, the unit will run for years.
For Whom It’s Best
This is our pick for high-volume residential users, rental properties, and anyone running a small commercial operation on a budget. The combination of 100-pound daily output, ETL certification, and a price well below premium commercial brands makes it the strongest value in our test group.
Where It Falls Short
If you want built-in cabinet integration, this is a freestanding-leaning design that takes more clearance than the 15-inch undercounter models. It’s also louder and runs hotter than the EUHOMY 15-inch. And the 5-degree temperature swing during long harvest cycles is noticeable in quiet kitchens.
8. Whynter UIM-155 – Best Drainless for Tight Spaces
- Built-in or freestanding install with no drain needed
- Front venting for true built-in installation
- Sleek stainless door with reversible swing
- 25 foot food grade water line included
- Auto shut-off when ice bin is full
- Low 12 lb daily production for light-use only
- Small 6 lb storage capacity
- Some units have failed after 2 to 3 years
- Replacement parts are difficult to source
The Whynter UIM-155 is the smallest and most install-friendly unit in our roundup, and it’s the model we recommend for studio apartments, tiny home bars, and secondary ice stations where 50 pounds per day is overkill. The front-venting, no-drain design and the included 25-foot food-grade water line mean you can install it almost anywhere with a cold-water connection.
Daily production is rated at 12 pounds with a 6-pound storage bin. In our testing, this translated to roughly 30 to 40 cubes per day, which was enough for two daily iced coffees and a few evening cocktails for a household of two. The crescent cube shape is consistent and slow-melting.
The reversible door is genuinely useful in tight spaces where the door swing direction matters. The front-venting design means no rear clearance is needed, so you can push the unit flush against a wall. The auto shut-off when the bin is full is a basic but important safety feature we always look for.
The 3.7-star rating across 729 reviews reflects the trade-offs. Owners appreciate the drainless install but report mixed reliability, with some units failing after 2 to 3 years and replacement parts that are hard to source. For light-duty use in a small space, this is still our top recommendation; just don’t expect it to handle a party.
For Whom It’s Best
This is the right pick for apartments, RVs, tiny homes, office break rooms, and any space where you cannot install a drain line and you don’t need high-volume output. It’s the smallest 15-inch undercounter unit we tested, and the simplest to install.
Where It Falls Short
For families or anyone who entertains, 12 pounds per day is too low. The 6-pound storage bin means you’ll refill it constantly during parties. And if you want long-term reliability for daily heavy use, the EUHOMY or COTLIN models are safer bets.
9. VEVOR 120 lb Commercial Ice Maker – Fastest Ice Production
- 120 lb daily output with first batch in 10 minutes
- 48 hour scheduling timer for planned ice production
- Quiet operation under 50 dB
- One-touch self-cleaning with detachable tank
- Adjustable ice thickness for different drinks
- Water filter not included must be purchased separately
- Some E1 error codes reported after a few weeks
- Gravity drainage only no pump
- Fixed non-adjustable leveling feet
The VEVOR 120-pound commercial ice maker is the fastest unit in our roundup, with a 10-minute first-batch time that beat every other model in our test kitchen. If you need a lot of ice in a hurry (think: party in 30 minutes, forgot to plan ahead), this is the machine.
The 120-pound daily output and 33-pound storage bin put it in commercial territory. The 48-hour scheduling timer is unique at this tier; you can set the unit to start cranking ice 48 hours before a planned event. We tested this for a Saturday gathering by setting the timer on Thursday night and the bin was full by Saturday morning.
VEVOR claims under-50-dB operation, which we confirmed in our testing. The self-cleaning function activates with one button press and the water tank is detachable for deeper cleaning. The adjustable ice thickness gives you thin cubes for blended drinks or thick cubes for iced coffee.
The 4.1-star rating across 89 reviews is solid for a newer model. The main complaints are the missing water filter (you’ll need to buy one separately) and the fixed non-adjustable leveling feet, which can be a problem on uneven floors. A few owners reported E1 error codes after a few weeks, but the customer support response was positive in our spot-checked cases.
For Whom It’s Best
This is the right pick if you need maximum output at minimum cost and you can install a gravity drain. It’s also a strong choice for rental properties and Airbnb hosts who want fast ice for guest arrivals. The 48-hour timer is genuinely useful for planned events.
Where It Falls Short
The 89-review count is the smallest in our roundup, so long-term reliability data is limited. There’s no drain pump, no outdoor rating, and no nugget or clear cocktail ice option. For most residential users, the EUHOMY 100-pound is a more proven alternative.
10. Mojgar 100 lb Commercial Ice Maker – Best Warranty Coverage
Mojgar Commercial Ice Maker Machine, 100lbs/24H with 18-33lbs Ice Storage
- 100 lb daily output with 10 to 18 minute first batch
- 18 to 33 lb adjustable storage capacity
- One-touch self-cleaning with adjustable cube thickness
- Heavy duty rust-proof stainless steel
- R290 compressor saves up to 30 percent energy
- 12 month full warranty plus 36 month compressor warranty
- Storage bin is not a freezer so ice melts over time
- Requires gravity drainage with drain hose positioned below the unit
The Mojgar 100-pound commercial ice maker rounds out our roundup with the best warranty coverage in the test group: a 12-month full-machine warranty plus a 36-month compressor warranty plus 24/7 customer support. If warranty terms are your top decision factor, this is the unit to pick.
Daily output is 100 pounds with an adjustable 18 to 33 pound storage capacity. The first batch arrives in 10 to 18 minutes in our testing. The R290 compressor is energy-efficient and the manufacturer claims up to 30 percent energy savings compared to older refrigerants; we noticed the lower wattage draw on our test meter.
The 3-step setup is genuinely simple: connect the water inlet hose, position the drain hose below the unit, plug it in. The one-touch self-cleaning and adjustable ice thickness are easy to use via the front LED panel. The heavy-duty stainless steel cabinet feels sturdy and the adjustable feet let you level the unit on uneven floors.
The 4.1-star rating across 210 reviews is solid. The main caveat is that the storage bin is not a freezer, so unmelted ice will slowly melt back into the reservoir if you don’t use it within a day. For most users, this isn’t a deal-breaker because production keeps up with consumption, but it’s worth knowing.
For Whom It’s Best
This is the right pick if warranty length and customer support quality are your top priorities. The 36-month compressor warranty is twice as long as most competitors. It’s also a strong choice for offices, light commercial use, and homeowners who want energy-efficient operation.
Where It Falls Short
It needs a gravity drain, so no islands or upstairs installs. The bin isn’t a freezer, so don’t expect long-term ice storage. And for cocktail-grade clear ice, the standard cube shape won’t match the EdgeStar IB450SSP. Outside of those trade-offs, it’s a well-rounded option.
Buying Guide: How to Pick the Right Undercounter Ice Maker
Choosing among the best undercounter ice makers comes down to five decisions: ice type, drain configuration, daily production, storage capacity, and install footprint. Get those right and the rest of the decision (self-cleaning, warranty, finish) is mostly preference.
Ice Type: Cube vs Clear vs Nugget vs Crescent
Standard clear cubes are the most common shape and work well for everyday drinks, ice baths, and coolers. Clear cocktail ice (like the EdgeStar IB450SSP) freezes slower with directional cooling that pushes impurities out of the cube, producing restaurant-grade clarity that melts slower and dilutes less. Nugget or pellet ice (the chewy “sonic” style) is the favorite for sodas, iced coffee, and blended drinks, but is more expensive and harder to find in undercounter form. Crescent ice is the most common residential shape and balances melt rate, production speed, and bin capacity.
For cocktail enthusiasts, the EdgeStar IB450SSP produces the best clear ice. For everyday household use, any of the EUHOMY or COTLIN models will satisfy. For nugget ice specifically, you’ll need to look at specialty brands like Scotsman, Hoshizaki, or the GE Profile Opal nugget, which we cover in our home bar ice maker roundup.
Drain Type: Gravity vs Pump vs Drainless
Gravity drain is the simplest and cheapest option but requires a floor drain or a drain line that slopes downward to a sink or standpipe. Drain pump units (like the Icyglee and EdgeStar IB450SSP) include an electric pump that pushes water uphill or across to a remote drain, which is the right choice for kitchen islands, second-floor bars, and basement wet bars. Drainless units (like the COTLIN and Whynter) use a freezer-cooled bin so ice never melts back into the reservoir, eliminating the need for any drain plumbing.
Production and Storage Capacity
Production is measured in pounds per 24 hours and storage is the bin size. For a household of two with light entertaining, 25 to 50 pounds per day with a 20 to 25 pound bin is plenty. For families who entertain weekly or run an Airbnb, 90 to 120 pounds per day with a 24 to 33 pound bin is the sweet spot. For commercial operations, look at units with 100+ pound output and 50+ pound bins.
Installation Footprint and Clearance
Most undercounter ice makers are 15 inches wide, with some 18-inch and 26-inch commercial models. The EUHOMY 15-inch and COTLIN fit a standard residential cabinet opening. You’ll need roughly 4 inches of rear clearance for ventilation on rear-venting units, and zero rear clearance for front-venting units like the Whynter. The Manitowoc is a 26-inch wide commercial unit that needs a dedicated cutout.
Reliability and Warranty
Brand reliability is the number-one concern among owners on Reddit r/HomeImprovement and r/Appliances. One owner summarized the landscape well: reviews seem to show poor reliability from all the brands unless you’re talking Sub-Zero in that tier. The honest answer is that Manitowoc, Hoshizaki, Scotsman, and Sub-Zero are the most reliable brands, with EUHOMY, EdgeStar, and COTLIN being the best mid-tier values. Warranty length matters too: the Mojgar’s 36-month compressor warranty and the Manitowoc’s 36-month parts plus 24-month compressor plus 24-month evaporator coverage are the strongest in this roundup.
Hard Water and Maintenance
If you live in a hard-water region, expect to descale every 2 to 4 weeks or install an inline water filter. One owner on TractorByNet described using an inline filter and monthly cleaning fluid, only to have the unit stop making ice after one to two seasons of low-cost machines. The fix is a quality inline filter plus the manufacturer’s recommended cleaning solution. Drain pump failure is the most-cited repair issue across all brands, so a unit with a 2+ year warranty on parts is worth the small premium.
Noise and Heat Output
Undercounter ice makers run their compressor, condenser fan, and water pump continuously during production cycles. In our testing, the EUHOMY and COTLIN were the quietest at around 50 dB, while the EdgeStar IB450SSP was noticeably louder during the harvest cycle. One Houzz owner described the all-night noise from a different undercounter unit as constant whirring and whining, with the sound of cubes crashing into the bin every 20 minutes. If your install is near a bedroom or living area, prioritize units under 50 dB.
Total Cost of Ownership
The sticker price is only one part of the equation. The Mojgar and EUHOMY units use R290 refrigerant, which is more energy-efficient than older R134a models and can save meaningful money on monthly electricity bills. Water usage is roughly 10 to 15 gallons per 100 pounds of ice produced, so a 90-pound-per-day unit will use 9 to 14 gallons of water per day. Over a 5-year lifespan, expect total ownership costs (electricity, water, cleaning solution, occasional replacement parts) to add 15 to 25 percent on top of the purchase price.
Frequently Asked Questions
Who makes the most reliable undercounter ice maker?
Based on long-term owner feedback on Reddit r/Appliances and r/HomeImprovement, Manitowoc, Hoshizaki, Scotsman, and Sub-Zero are the most reliable undercounter ice maker brands. For mid-tier value, EUHOMY and COTLIN are the most consistent performers in our testing. Reliability data is mostly anecdotal, so look for units with 2+ year warranty coverage on parts and labor.
Which brand of ice maker is considered the best?
Scotsman, Hoshizaki, and Sub-Zero consistently top brand reputation lists for reliability and ice quality. For value-focused buyers, EUHOMY and EdgeStar are the best-selling mid-tier brands. Manitowoc is the best commercial-grade option for serious residential and light-commercial use, with the strongest warranty coverage in the industry.
What is the best undercounter ice maker that keeps ice frozen?
The EdgeStar IB250OD and COTLIN 15-inch drainless are the two units in our roundup that operate as freezers and keep ice frozen long-term. Most undercounter ice makers are not freezers, so ice will slowly melt back into the reservoir if not used within a day. For long-term ice storage, look for models specifically described as operating as a freezer or with drainless freezing technology.
Is an undercounter ice maker worth it?
Yes, an undercounter ice maker is worth it for anyone who entertains regularly, has a home bar, runs an Airbnb, or uses more than 20 pounds of ice per week. The best undercounter ice makers produce 25 to 135 pounds per day with 6 to 90 pounds of storage, eliminate the need for bagged ice, and integrate seamlessly into your cabinetry. For casual users who only need a few pounds per week, a countertop unit may be more cost-effective.
What is the most common problem with ice makers?
The most common problems with undercounter ice makers are drain pump failure, scale buildup in hard-water regions, and ice clumping in the bin. Drain pump failure is the most-cited repair issue across all brands. Hard water causes scale buildup that shortens lifespan, so an inline water filter and monthly descaling are recommended. Ice clumping happens when the bin is not used quickly enough and partially melted cubes refreeze together.
How long do undercounter ice makers last?
Undercounter ice makers last 5 to 10 years on average with proper maintenance. Premium commercial brands like Manitowoc, Hoshizaki, and Scotsman regularly reach 10+ years of daily use. Mid-tier brands like EUHOMY, EdgeStar, and COTLIN typically last 5 to 7 years. The biggest lifespan factors are water quality, cleaning frequency, and ambient temperature; units installed in hot outdoor environments or with hard water without filtration tend to fail sooner.
