Best Undercounter Ice Makers

TL;DR: The SPT Undercounter Ice Maker delivers 12 lb of crescent‑shaped ice daily in a compact 15‑inch‑wide stainless‑steel package, featuring a reversible door, front exhaust fan, and no‑drain installation, but its modest output and manual defrost suit light‑to‑moderate use.

At the heart of the SPT IM‑150US is a daily ice production of 12 lb and a storage bin that holds 6 lb of crescent‑shaped cubes. Its footprint measures 18 inches deep, 25 inches high and 15 inches wide, allowing it to slide into tight under‑counter spaces where wider units simply won’t fit. The reversible door lets you choose left‑ or right‑hand opening, and the front‑mounted exhaust fan provides the ventilation needed for a true built‑in installation.

When you line it up against the seven other models in this roundup, the SPT sits in the middle of the weight range at 55 pounds—lighter than the Coolake (61 pounds) and Whynter (62 pounds) units, but heavier than the Frigidaire (33 pounds) and Cowsar (32.45 pounds) machines. Its 18‑inch depth matches the Whynter but exceeds Coolake’s 14.6‑inch depth, while the 15‑inch width is identical to Whynter and noticeably narrower than Coolake’s 19.7‑inch width. In terms of output, the SPT ties with Whynter’s 12 lb/day production, yet it falls far short of Coolake’s 200 lb/day, Ice‑O‑Matic’s 63 lb/day, and Cowsar’s 66 lb per day capacity.

Reviewers consistently praise the compact design for fitting into cramped kitchens, apartments, or office wet bars. The included 25‑ft water line and the fact that no dedicated drain is required make installation feel straightforward, and the front exhaust fan earns kudos for keeping the unit cool when tucked under a countertop. On the flip side, users note that the manual defrost cycle adds a routine chore, and the 12‑lb daily output can feel limiting during larger gatherings or high‑traffic bar settings.

Technically, the unit runs on 115 V at 60 Hz, drawing 3.7 A and consuming 112 W of power. An auto shut‑off feature halts production once the 6‑lb bin is full, preventing overflow. The stainless‑steel door paired with a black cabinet gives it a sleek look that blends with most décor, while the manual defrost requirement remains the only maintenance step that can’t be automated.

Best for: Those prioritizing quality and willing to pay for premium performance

Avoid if: You're on a tight budget or only need basic functionality

TL;DR: The Icyglee CIM001‑100BS churns out up to 100 lb of full‑size cube ice per day, stores 33 lb in a stainless‑steel bin, and runs ultra‑quietly for under‑counter use.

The headline spec's 100 lb/24 h ice production is backed by a rapid 6‑minute batch cycle and a 24‑hour programmable timer. An LCD control panel lets you pick from three ice‑size options, while the built‑in infrared overflow sensor stops the machine before the bin overfills. At 29,483 g, the unit's sturdy enough for commercial use yet still fits a typical under‑counter space with its 405 mm depth, 795 mm height, and 445 mm width.

Compared with the seven other models in this roundup, the Icyglee outpaces most on daily output: it tops Frigidaire’s 33 lb/day, Whynter’s 12 lb/day, Cowsar’s 66 lb/24 h, SPT’s 12 lb/day, Ice‑O‑Matic’s 63 lb/day, and Hoshizaki’s 55 lb/24 h, though it sits below Coolake’s 200 lb/day. In weight, it's heavier than Frigidaire’s 33.0 lb and Cowsar’s 32.45 lb units, but it's lighter than Hoshizaki’s 120.8 lb machine, placing it in the mid‑range for portability.

Users consistently praise the rapid 6‑minute ice cycle and the ultra‑quiet operation, noting that the self‑cleaning feature reduces manual maintenance.

Professional reviewers highlight the infrared sensor and ETL certification as confidence‑boosting safety touches.

The most common complaints involve dimension inconsistencies across listings, which can make cabinet fitting tricky, and the requirement for at least 2 inches of ventilation clearance on all sides to keep performance optimal.

Best for: Small businesses, home bars, or office break rooms that need up to 100 lb of ice daily without sacrificing quiet operation.

Avoid if: Your space lacks the required ventilation clearance, you need more than 200 lb of ice per day, or you rely on built‑in water filtration.

TL;DR: The Coolake IM90 delivers a massive 200 lb of clear, 0.9‑inch cubes each day in a compact under‑counter package, but it carries a premium price tag.

This unit’s headline spec is its 200 lb/day ice production capacity, paired with a 24 lb storage bin that can hold enough cubes for a busy home bar or small office. The machine makes uniform cube‑shaped ice, and reviewers say it looks “clear” and “professional.” Its footprint—19.7 in wide, 14.6 in deep and 32.9 in high—fits most under‑counter spaces while still offering a sizable bin.

When you line it up against the seven other models, the Coolake outpaces them on output: the nearest competitor tops out at 66 lb per day, and most peers store only 6‑8 lb of ice. Its 24 lb bin holds more than double what many rivals can. The width of 19.7 in is broader than the typical 12‑15 in found elsewhere, yet its 14.6 in depth is shallower than several, making it a good compromise for tight kitchens. Weightwise, at 61.0 lb it sits near the heavier end of the group, lighter than the 120.8‑lb Hoshizaki but heavier than the 33‑lb Frigidaire.

Customer feedback highlights the steady supply of clear cubes and the unit’s efficient design, but several reviewers point out that the listed weight fluctuates between 62 lb and 72 lb across retailers, suggesting spec inconsistencies. Professional reviewers also note that the air‑cooled system needs adequate ventilation and a permanent water hookup to run reliably.

Best for: Home and office users seeking a balance of features and value

Avoid if: You're shopping on a tight budget — it's priced at $429.98

TL;DR: The Whynter UIM-155 delivers 12 lb of crescent‑shaped ice daily in a compact 15‑by‑25‑inch footprint, but its modest output and 3.6‑star rating may limit heavy‑use scenarios.

The standout spec is its daily ice production of 12 lb, which it stores in a 6‑lb crescent‑type bin. Its dimensions—15.0 in width, 25.0 in height, and 18.0 in depth—make it one of the tighter‑fitting undercounter models, and it weighs 62.0 lbs.

Compared with peers, the UIM-155 is deeper than the ICYGLEE’s 405 mm depth and lighter than its 29,483 g weight, while matching the SPT’s 18‑in depth and 25‑in height. It’s narrower than Coolake’s 19.7 in width and heavier than Frigidaire’s 33.0 lb unit. Its 12 lb/day output trails Frigidaire’s 33 lb/day, Coolake’s 200 lb/day, and Ice‑O‑Matic’s 63 lb/day, but aligns exactly with SPT’s 12 lb/day production.

User feedback praises the compact size for tight kitchens and the single‑button operation that reliably creates crescent ice, while noting the lack of a drain connection as a convenience. However, the 3.6/5 rating from 698 reviews signals mixed satisfaction, with some owners wishing for higher daily output during large gatherings. Professional reviewers highlight its CFC‑free, high‑efficiency design, note that it draws 120 W at 1.8 A, and say it can be installed built‑in or freestanding with front venting.

Best for: Value-conscious buyers seeking quality at $319.99

Avoid if: You need advanced features or professional‑grade performance

TL;DR: The Cowsar under‑counter ice maker churns up to 66 lb of cube ice a day, fits in a compact 339 mm footprint, and earns a perfect 5‑star rating for its quiet, self‑cleaning operation.

This unit’s headline spec is its 66 lb per 24 h ice production capacity, paired with an 8 lb storage bin that holds enough cubes for a small café or a busy home bar. The cubes measure 22 × 22 × 22 mm, and the thickness can be adjusted via the digital LCD panel. An automatic cleaning function means you'll keep the stainless‑steel interior hygienic with a single button press.

At 32.45 lb, the Cowsar is about the same weight as the Frigidaire 3‑in‑1 model (33 lb) but considerably lighter than the Whynter UIM‑155 (62 lb) and the Coolake commercial unit (61 lb). Its depth of 339 mm is slightly deeper than Frigidaire’s 12.0 in (≈305 mm) yet far shallower than the ICYGLEE’s 405 mm, and the 602 mm height gives it a lower profile than many freestanding competitors. This compact size makes it a true under‑counter candidate for tight spaces.

Five reviewers have awarded it a flawless 5.0‑star rating, repeatedly noting the food‑grade stainless‑steel construction and the one‑button automatic clean as major conveniences. Users also appreciate the quiet operation measured at 55 dB, which keeps kitchen noise to a minimum.

Technically, the machine is air‑cooled and uses R290 refrigerant (52 g). It connects to a water line with a 6.35 mm diameter fitting and works with supply pressures between 0.04‑0.6 MPa. A 20 mm insulation layer helps maintain efficiency, and the unit carries an ETL certification and a 12‑month warranty for peace of mind.

Best for: Entry‑level buyers or those on a tight budget who need reliable, quiet cube ice in a small footprint.

Avoid if: You need advanced features, larger ice storage, or professional‑grade production capacity.

TL;DR: The Hoshizaki AM-50BAJ-AD delivers up to 55 lb of top‑hat ice daily in a compact, ADA‑compliant undercounter package, but its premium price and noticeable noise may limit appeal.

This model pushes 55 lb of ice per 24‑hour cycle and stores 22 lb in a stainless‑steel bin, letting you keep a steady supply of top‑hat cubes for a busy bar or small kitchen. Its front‑in/front‑out airflow eliminates the need for side or rear clearances, and the unit meets ADA requirements while also carrying a UL outdoor rating for added durability.

Compared with the seven other undercounter options, the Hoshizaki sits at the higher end of the price spectrum and is noticeably heavier than the SPT (55 lb) and Whynter (62 lb) models. Its height of 31.5 in makes it taller than the Ice‑O‑Matic (25.25 in) but still shorter than the Coolake’s 32.9 in profile. In terms of ice output, it outpaces most peers that top out around 12–63 lb per day, though the Coolake unit lists a 200‑lb daily capacity.

Users consistently praise the compact footprint (14.88" × 22.63" × 31.5") and the sleek stainless finish, noting that the front‑airflow design simplifies installation in tight spaces. Professional reviewers highlight the reduced number of moving parts as a durability benefit. The most common complaint is a noticeable noise level that can be disruptive in quiet environments, and the product’s 3.0‑star rating suggests mixed satisfaction. Hoshizaki discontinued it in favor of the newer AM‑50BAK‑AD model.

Technical details include a 0.5‑inch water inlet, 3.8 A draw, and a 6‑ft power cord, with an energy use of 16.8 kWh per 100 lb of ice produced. Water consumption sits at 71.0 gallons per 100 lb, and the machine runs on R‑134a refrigerant (120 g). The two‑year parts‑and‑labor warranty rounds out the offering.

Best for: Those prioritizing quality and willing to pay for premium performance

Avoid if: Reliability and user satisfaction are your top concerns

TL;DR: The Ice‑O‑Matic UCG060A delivers 63 lb of clear gourmet cubes daily in a compact 15.25‑in wide, 20‑in deep undercounter package, but its $2093 price tags it as a premium choice.

This model’s standout spec is its 63 lb/day ice production, enough to keep a small bar or café well‑stocked without constant refills. It fits under a counter at 20.0 in depth, 25.25 in height and a narrow 15.25 in width, while the built‑in storage bin holds 17.5 lb of ice.

Compared with the other seven units, the UCG060A has a deeper profile than the 14.6‑in depth of the Coolake model and the 18‑in depth of the SPT maker, yet its 15.25‑in width is slightly wider than the 15‑in widths of the SPT and Whynter machines and considerably slimmer than Coolake’s 19.7‑in width. Its 63‑lb daily output sits just below the Cowsar’s 66‑lb capacity and well above the 12‑lb outputs of SPT and Whynter, while surpassing Hoshizaki’s 55‑lb per‑day rate but trailing the Coolake’s 200‑lb powerhouse.

Professional reviewers say the clear, long‑lasting gourmet cubes and the stainless‑steel, fingerprint‑proof plastic construction add durability and easy front‑access service. Users, however, frequently mention a loud refill cycle that can be disruptive in front‑of‑house areas. The machine runs on R290A refrigerant, a hydrocarbon blend that lowers environmental impact compared with older gases.

TL;DR: The Frigidaire 3‑in‑1 Ice & Water Machine offers bullet‑shaped ice at 33 lb per day, hot and cold water, and a compact 12‑in footprint for $249.99.

This unit’s standout spec is its 33 lb/day ice production capacity, with a batch of nine cubes forming in 7‑11 minutes. It delivers bullet‑type ice, and its overall dimensions are 12.0 in deep, 12.0 in wide, and 33.0 in tall, while weighing 33.0 lb.

Compared with the other seven undercounter models, the Frigidaire outproduces the Whynter UIM‑155 and the SPT Undercounter Ice Maker, both listed at 12 lb of ice per day. It falls short of the Cowsar Commercial Ice Maker’s 66 lb per 24 h, the Coolake Commercial’s 200 lb/day, the Ice‑O‑Matic’s 63 lb/day, and the Hoshizaki’s up to 55 lb per day. In size, its 12‑in depth and width are smaller than the ICYGLEE Commercial Ice Maker’s 405 mm depth and 445 mm width, making it fit tighter in cramped kitchens. At 33 lb, it is lighter than the Whynter (62 lb) and the Coolake (61 lb) models, though the ICYGLEE lists weight in grams, indicating a heavier unit.

User feedback highlights the convenience of having hot water, cold water, and bullet ice from a single freestanding appliance. Reviewers praise the high ice output of 33 lb/day, but note that the internal ice storage holds only about 2.5 L (≈2.9 lb), which can require frequent refilling during extended use. A Prop 65 warning about potential lead exposure also appears in the product literature, prompting caution for health‑conscious buyers. The machine’s 4.0‑star rating from 94 reviewers suggests solid satisfaction for its price tier.

Best for: Small households, home offices, or RV owners who want on‑demand hot and cold water plus occasional bullet ice without breaking the bank.

Avoid if: You need a high‑volume ice supply for large gatherings, or you prefer to steer clear of products with a Prop 65 lead warning.
