An undercounter ice maker is a dedicated appliance that turns the daily scramble for bagged ice into a distant memory. Choosing the wrong one, however, can mean weeks of troubleshooting drainage issues, noisy compressors, and ice that melts before it hits your glass. The narrow distinction between a gravity-drain unit and a pump-equipped model can make or break your installation, so understanding that spec alone separates a seamless fit from a costly mistake.
I’m Mohammad Maruf — the founder and writer behind AirfryerBite. I have spent years analyzing the hardware specifications and real-world performance data of kitchen appliances, focusing on the undercounter ice maker category where installation requirements, daily yield, and bin capacity determine long-term satisfaction.
After comparing daily production rates, storage bin sizes, refrigerant types, and drain requirements across dozens of models, I have assembled the definitive guide to help you find the rated undercounter ice maker for your home bar, kitchen, or commercial space.
How To Choose The Best Rated Undercounter Ice Maker
Selecting an undercounter ice maker starts with three fixed parameters: the physical space under your counter, the proximity to a water supply and drain, and how much ice you realistically need per day. Ignoring any one of these three will lead to a machine that either doesn’t fit, cannot be properly installed, or leaves you running out of ice mid-party.
Drainage Type: Pump, Gravity, or Drainless
This is the most critical decision. Gravity-drain models require the drain hose to be lower than the machine’s outlet, which usually means you need a floor drain or a sink drain below the unit’s height. Models with an integrated drain pump can push water upward, allowing installation in basements or locations where the drain is above the machine. Drainless models use a reservoir that recirculates melted ice water, eliminating the drain line entirely, but they typically require manual emptying of the reservoir periodically and may need more frequent cleaning to prevent bacteria buildup.
Daily Production vs. Bin Capacity
Daily production, measured in pounds per 24 hours, tells you how fast the machine replenishes ice. Bin capacity, measured in pounds, tells you how much ice the unit holds at once. For home use, a 50 lb/day machine with a 25 lb bin is usually sufficient. For frequent entertaining or light commercial use, look for 80–120 lb/day production with at least a 30 lb storage bin. The key spec to check is the actual cubic footage of the bin relative to the daily yield — oversized production paired with a tiny bin means the machine will cycle on and off frequently.
Ice Shape and Quality
Bullet ice (hollow-center cylinders) and crescent ice (solid, slow-melting) are most common in budget-friendly undercounter units. Clear cube machines produce dense, restaurant-style cubes by purging impurities during freezing, but they are typically more expensive and may have lower daily yields. Nugget ice, also called pebble or Sonic ice, is soft and chewable, making it a favorite for soda and blended drinks but requiring a more specialized mechanism that can be less reliable over time.

In‑Depth Reviews
1. ICYGLEE Commercial Undercounter Ice Maker with Drain Pump
The ICYGLEE hits the sweet spot of daily production and practical drainage flexibility. Its built-in drain pump means you are not forced to position the unit above a floor drain — the pump pushes water up to a sink drain or laundry box, which opens up installation options in finished basements and island bars where gravity drainage is impossible. The unit produces 100 lbs of clear ice cubes per day with an 8–16 minute cycle time, and the 24 lb storage bin refills fast enough to keep up with back-to-back drink service.
The adjustable ice thickness and 24-hour timer give you precise control over cube size and operating schedule, while the self-cleaning function simplifies maintenance. Owners note that the drain hose must be kept short to prevent leaks, and the pump requires a 10-inch drop below the machine for proper priming — a detail that trips up some installers who assume the internal pump handles all lift.
At this price point, the ICYGLEE delivers features found on machines costing significantly more, including a reversible door and R290a refrigerant. If your installation site lacks a gravity drain, this model is the most reliable entry into the category.
Why it’s great
- Integrated drain pump allows placement where gravity drain is not available.
- Rapid cycle time (8–16 minutes) keeps the bin full during heavy use.
- Adjustable cube thickness and 24-hour timer add scheduling flexibility.
Good to know
- The drain pump requires a minimum drop of 10 inches below the machine, which limits some cabinet placements.
- The 24 lb bin is smaller than some competitors at the same daily production rate.
2. Gilati 120 lbs/Day Undercounter Ice Maker
The Gilati pushes daily production to 120 lbs, making it one of the most aggressive performers in the mid-range tier. Each cycle delivers 40 clear cubes in 10–16 minutes, and the 30 lb storage bin provides a 6-hour buffer before the machine needs to catch up from empty. The 15-inch width fits standard undercounter cavities, and the three-layer insulated door keeps stored ice from clumping together during low-demand periods.
The gravity-drain design keeps the price accessible, but it also means the unit must be positioned so the drain hose runs downhill to a floor drain or sink trap. Some buyers report that the included drain hose is too flexible and prone to kinking, which causes standing water in the reservoir — a braided stainless steel replacement hose eliminates that issue entirely.
The self-cleaning function and adjustable ice thickness are standard, but the 24-hour timer requires navigating a slightly unintuitive LCD panel. Overall, this machine delivers the highest daily yield in the group, making it ideal for households that host large gatherings or for light commercial use in a cafe or bar.
Why it’s great
- 120 lbs/day production is the highest daily yield in the mid-range comparison.
- The 30 lb storage bin provides a generous buffer between cycles.
- Three-layer insulated door reduces melting and ice clumping.
Good to know
- Gravity-drain only — a drain pump is not included.
- Some units arrive with a kink-prone drain hose that needs replacing.
3. COTLIN Drainless Undercounter Ice Maker
The COTLIN is the first drainless model in this lineup, using a recirculating reservoir that eliminates the need for any drain line connection. This makes it the easiest unit to install — you only need to connect the water supply line and plug it in. The crescent-shaped ice cubes are solid and slow-melting, which makes them a strong choice for whiskey or iced tea where dilution is undesirable. The machine produces 42 lbs of ice per day with a 22 lb storage bin, which is adequate for a household of four but will feel limiting during parties.
The R600a refrigerant is slightly less energy-dense than R290a, and the compressor runs at a moderate hum that owners describe as whisper-quiet compared to older units. The door is reversible, and the adjustable leveling legs handle uneven floors. Because there is no drain line, you do need to manually empty the reservoir every few weeks to prevent stagnant water, and the manufacturer recommends a full cleaning cycle monthly to avoid biofilm buildup.
If you cannot run a drain line under your counter, the COTLIN is the most practical solution. The trade-off is a lower daily yield and the need for periodic reservoir maintenance.
Why it’s great
- No drain line required — installs with only a water supply connection.
- Crescent ice is dense and melts slowly, reducing drink dilution.
- ETL certified and backed by a lifetime service warranty.
Good to know
- Daily production of 42 lbs is low compared to similarly priced competitors.
- The reservoir requires manual draining and periodic cleaning to prevent bacteria growth.
4. EUHOMY Undercounter Nugget Ice Maker 70 lbs/Day
The EUHOMY Nugget Ice Maker is purpose-built for people who crave the soft, chewable texture of Sonic-style nugget ice. It produces 70 lbs of pebble ice per day using a specialized auger mechanism that shaves ice into compressed nuggets. The double-layer ice basket design provides continuous dispensing — as you scoop from the upper basket, the lower basket fills in, reducing the time you wait for the machine to cycle. The nugget ice is crisp and absorbs syrup flavor well, which is why it is popular in coffee shops and soda fountains.
Installation requires a gravity drain with an air gap, and the instructions are sparse — several buyers recommend buying an external condensate pump if the drain line runs uphill. The unit measures 15 inches wide and fits under a standard counter, but the 33-inch height means you need at least 34.5 inches of clearance. The 24-hour timer and self-cleaning function work well, and the LCD panel displays ambient temperature for quick diagnostics.
The biggest caveat is reliability: nugget ice mechanisms are mechanically more complex than bullet or crescent systems. Some owners report the auger jamming after a year of heavy use, though EUHOMY’s 1-year warranty covers manufacturing defects.
Why it’s great
- Produces true nugget ice that is soft, chewable, and beverage-friendly.
- Double-layer ice basket reduces downtime between scoops.
- Compact 15-inch width fits standard undercounter cavities.
Good to know
- Gravity drain only; an external pump is needed if the drain line must go upward.
- The auger-style mechanism is less durable than traditional ice makers and may require service within 1–2 years.
5. EdgeStar IB450SSP 50 lb Undercounter Clear Ice Maker
The EdgeStar IB450SSP is a commercial-grade undercounter ice maker that produces restaurant-quality clear cubes in sheet form. The ice comes out as a full sheet that you break apart manually, which gives you the dense, slow-melting cubes that bartenders prefer for cocktails. The built-in drain pump handles lift up to 8 feet, so this unit can be installed in a basement bar or on an interior island where floor drains are not available. Production is rated at 50 lbs per day with a 25 lb storage bin, which is conservative compared to the 100+ lb machines in this list but appropriate for a home bar that sees consistent but not marathon use.
The commercial-grade stainless steel door and reversible hinge add to the premium feel, and the computerized controls let you adjust the ice thickness. Installation by a licensed plumber is recommended because the drain line must be terminated with an air gap. The R134a refrigerant is being phased out in newer models, but the machine still runs efficiently and quietly when properly maintained.
Long-term reliability is a mixed picture: some owners report the unit running flawlessly for years, while others cite loud operation and failures after 18 months. The 25 lb bin is also smaller than it appears — the unit is not a freezer, so ice will melt faster if you leave it overnight.
Why it’s great
- Produces clear, dense sheet ice that breaks into restaurant-quality cubes.
- Built-in drain pump supports installations where gravity drainage is impossible.
- Commercial-grade stainless steel construction and reversible door.
Good to know
- Ice comes out in sheets that require manual breaking — not pre-formed individual cubes.
- Long-term reliability is inconsistent; some units become loud or fail after 18 months.
6. TAZPI 160 lbs/Day Commercial Undercounter Ice Maker
The TAZPI is the highest volume machine in the lineup, churning out 160 lbs of ice per day with a 35 lb storage bin. It produces 63 bullets of ice per cycle, making it ideal for a high-traffic kitchen, catering setup, or convenience store where ice demand is relentless. The LCD panel includes ice thickness adjustment, a timer, and an auto-clean function, and the R290a refrigerant is both energy-efficient and environmentally favorable compared to older refrigerants.
The unit is 15 inches wide but 31.5 inches tall, so verify your undercounter clearance before purchasing. The gravity-drain design requires a drain line below the machine, and owners recommend using a braided hose to prevent kinking. The included water inlet and drain pipes are functional but basic — you will likely need to buy your own compression fittings for a leak-free connection.
Customer service from TAZPI gets mixed marks: some buyers report quick replacements for defective units, while others describe a lengthy troubleshooting process. The machine produces bullet ice that is less dense than crescent or cube styles, so it dilutes drinks faster — a trade-off for the enormous production capacity.
Why it’s great
- 160 lbs/day production dwarfs most undercounter competitors.
- 35 lb storage bin is the largest in the comparison.
- Fast cycle time — 63 cubes in 11–20 minutes.
Good to know
- Bullet ice melts faster than crescent or clear cube styles.
- Customer service responsiveness varies significantly according to user reports.
7. Mojgar ETL Undercounter Ice Maker 100 lbs/Day
The Mojgar brings ETL safety certification and a reversible double-door design that opens from either left or right, which is a rare convenience for tight cabinet layouts. It produces 100 lbs of ice per day with a 30 lb storage bin, and the commercial-grade hard ice melts slowly, making it a solid choice for bar environments where ice longevity matters. The LCD touch screen integrates ice thickness adjustment, a scheduled timer, and real-time temperature display — all controlled through a responsive panel.
The stainless steel exterior with 304-grade food-contact surfaces and a three-layer vacuum insulation foam door boosts energy efficiency by 25% over industry averages, according to the manufacturer. The gravity-drain system requires minimal plumbing modifications, and the removable ice bucket simplifies cleaning. Some owners report that the unit is louder than expected during the freezing cycle, though the noise level is comparable to a refrigerator compressor.
Installation is straightforward for a handy person, but the drain line must be routed downhill — no pump is included. The Mojgar represents a strong balance of certified safety, daily output, and a user-friendly interface at a mid-range price.
Why it’s great
- ETL safety certification provides peace of mind for residential and light commercial use.
- Reversible double-door adds installation flexibility in tight spaces.
- Three-layer insulation reduces energy consumption.
Good to know
- Operating noise is noticeable during the freezing cycle.
- Gravity-drain only — not compatible with locations that lack a lower drain point.
8. EUHOMY CIM002-80S 85 lbs/Day Undercounter Ice Maker
The EUHOMY CIM002-80S is a 15-inch-wide undercounter ice maker that produces 85 lbs of clear cube ice per day with a 24 lb storage bin. Each cycle yields 40 cubes in 10–18 minutes, and the adjustable ice thickness lets you choose between smaller cubes for rapid cooling and larger cubes for slower dilution. The reversible door and three-layer insulated housing are standard, and the self-cleaning function simplifies maintenance. The 24-hour timer allows you to schedule ice production during off-peak hours.
Installation requires a gravity drain, and the machine must remain upright for 24 hours before the first startup to allow the compressor oil to settle. The 1-year manufacturer warranty covers defects, but some owners report that the LCD panel is difficult to read in direct sunlight if the unit is placed near a window. The ice quality is consistent, with minimal cloudiness, and the bullet-shaped cubes stack efficiently in the storage bin.
This model is a no-frills workhorse for someone who needs reliable daily ice production without paying extra for a drain pump or nugget ice mechanism. The 85 lb daily output keeps up with a busy household, though the 24 lb bin means you will need to transfer ice to a freezer during heavy entertaining.
Why it’s great
- Compact 15-inch width fits under most standard countertops.
- Reliable 85 lbs/day production with adjustable cube thickness.
- Self-cleaning function and 24-hour timer reduce manual effort.
Good to know
- 24 lb bin fills up quickly during large gatherings — may require supplemental freezer storage.
- 1-year warranty is shorter than some competitors in the same price tier.
9. RAPSUAR 95 lbs/Day Undercounter Ice Maker
The RAPSUAR produces 95 lbs of ice per day with a 35 lb storage bin, which is one of the largest bin capacities relative to daily yield in the mid-range tier. The first batch of 40 cubes drops in 10 minutes, making it one of the fastest-starting machines in this comparison. The bullet ice drops into a removable bin, and the three-layer insulated housing keeps the ice from melting too quickly between servings.
The LCD panel includes a 24-hour timer and adjustable ice thickness, but the interface layout is not as intuitive as the touch-screen designs found on higher-tier models. The unit measures 17 inches deep and 19 inches wide — wider than the standard 15-inch format — so verify your cabinet opening before buying. Some owners report that the door hinge is not as robust as the stainless steel body suggests, and a few have experienced the door loosening after several months of use.
The ice quality is good for bullet-style — clear and uniform — and the 750-watt compressor is noticeably more powerful than the 200-watt units in this list, which translates to faster recovery after the bin is emptied. The RAPSUAR is a strong choice if bin capacity and cycle speed are your top priorities.
Why it’s great
- 35 lb bin is one of the largest in the mid-range tier.
- First batch of ice drops in approximately 10 minutes.
- 750-watt compressor provides rapid recovery after heavy use.
Good to know
- 19-inch width is wider than the standard 15-inch undercounter format.
- Door hinge durability has been questioned in longer-term user reports.
10. Joy Pebble Undercounter Nugget Ice Maker 66 lbs/Day
The Joy Pebble is a drainless nugget ice maker that produces 66 lbs of chewable pebble ice per day. Because it uses a recirculating reservoir instead of a drain line, it is one of the few undercounter nugget machines that can be installed in an RV, boat, or rental property where plumbing modifications are limited. The unit measures 15 inches wide and 33.1 inches tall, and it produces its first batch of nuggets in 10–15 minutes.
The triple-layer insulation keeps the nuggets from melting quickly, and the LCD panel includes a self-cleaning function and a 24-hour timer. The nugget ice is compressed and holds its shape in soda and cocktails for about an hour before dissolving, which is typical for this style. Some owners report that the machine produces excessive noise during the initial freeze cycle, and a few experienced a loud screeching sound after several months of use, suggesting the auger mechanism may be prone to wear.
The drainless design is the Joy Pebble’s strongest feature, but the 17.6 lb storage bin is small for a 66 lb/day machine, meaning the unit will cycle on and off frequently during high-demand periods.
Why it’s great
- Drainless design allows installation in RVs, boats, and rental properties without drain plumbing.
- Produces true nugget ice that is soft and chewable.
- Triple-layer insulation keeps ice fresh for longer.
Good to know
- 17.6 lb bin is small relative to the daily production rate.
- Some units develop loud screeching noises after several months of operation.
11. Electactic Commercial Nugget Ice Machine 66 lbs/Day
The Electactic is a 15-inch-wide undercounter nugget ice maker that produces 66 lbs of chewable ice per day with a dual-bin design that separates fresh ice from stored ice. The first batch drops in under 10 minutes, and the enhanced insulation keeps 80% of the ice unmelted for 12 hours. The LCD panel displays ambient temperature and provides alerts for low water and full ice conditions, plus a 12-hour timer for scheduling production around peak demand.
The gravity-drain design requires a drain line, and some owners note that the instructions are vague about the required air gap. The unit is 33.1 inches tall, so measure your undercounter clearance carefully. The removable ice basket makes it easy to transfer ice to a freezer for longer storage. The self-cleaning function simplifies maintenance, but the panel buttons feel slightly cheap compared to the otherwise solid stainless steel exterior.
Nugget ice enthusiasts will appreciate the soft texture and fast production, but the 66 lb daily output is modest for commercial use — this is best suited for a home kitchen or a small coffee shop that serves iced drinks moderately.
Why it’s great
- Dual-bin design separates fresh nugget ice from stored ice for consistent texture.
- 12-hour insulation retention keeps ice from melting quickly in the bin.
- First nugget batch in under 10 minutes.
Good to know
- Gravity-drain only, with vague instructions regarding the required air gap.
- 66 lbs/day output is modest for heavy commercial use.
