Best Small Undercounter Ice Maker: Deciding Specs

The best small undercounter ice maker for most kitchens is the EUHOMY IM-02, a 15-inch stainless unit rated at 100 lbs per 24 h with a 33 lb bin and a 1-year manufacturer warranty. If your kitchen has no floor drain, the drainless COTLIN HXSeries at 33.8 x 18.4 x 14.8 in is the better call, because it skips the plumbing question the other four still ask you.

How I screened the field down to five

I started with the listings Amazon returns for 15-inch class undercounter units and cut anything that could not confirm a width figure, a daily output figure, and a drainage approach. That left five. Every pick here publishes at least a width, a depth and a height, a weight, and a stated daily production rate. Three publish an ETL certification claim on the listing.

The word small is doing heavy lifting in this category. Amazon treats a 15-inch built-in as small because a full undercounter refrigerator is 24 inches. If you were hoping for a countertop nugget machine at half the size, none of these five is that. They are the smallest built-in class, not the smallest ice makers you can buy.

• Every unit fits a 15-inch nominal opening
• Every unit is freestanding-capable
• Four use a drain line, one is drainless
• Daily output runs from 90 lb to 110 lb
• Weights run from 42.3 lb to 66.6 lb

Best small undercounter ice maker at a glance

1. EUHOMY IM-02 — Best overall

The EUHOMY IM-02 is the best small undercounter ice maker for a kitchen that already has a floor drain, because it pairs a 100 lbs / 24 h output claim with the largest published bin in the set at 33 lb.

Best for: a busy kitchen or home bar with a nearby floor drain Skip it if: you cannot run a gravity drain line

The IM-02 measures 31.3 x 17.5 x 16 in and weighs 66.6 lb, the heaviest unit here. EUHOMY says the compressor turns out 45 clear cubes per 11 to 15 minute cycle and lets you dial the thickness through an LCD panel, which is useful if you swap between smoothie-friendly thin cubes and slower-melting thick ones for spirits. It is ETL certified per the listing. The warranty is 1 year manufacturer, and it is the only pick in the set with a warranty term printed on the specification block. Where the IM-02 loses points is drainage: the listing explicitly says gravity drainage only, with no pump included. That means a floor drain or a lower drain outlet under the cabinet, and if you have neither, the COTLIN drainless pick makes more sense. Against the ICEPURE, the EUHOMY trades Wi-Fi for a larger bin and a stated warranty.

Pros:

• Largest stated bin capacity in the set at 33 lb
• 100 lbs / 24 h production claim from EUHOMY
• Adjustable cube thickness via LCD panel
• 1-year manufacturer warranty printed on the spec sheet
• ETL certification claim on the listing

Cons:

• Gravity drain only, no pump option
• Heaviest unit here at 66.6 lb
• Body width of 17.5 in is wider than a 15 in cabinet cutout

2. Mojgar CIM-360F — Best budget pick

The Mojgar CIM-360F is the cheapest of the five and the lightest at 42.3 lb, which matters when you are shoving a stainless box into a cabinet alone.

Best for: the tightest cabinet width in the set at 15.2 in body Skip it if: you need a published warranty in writing

At 29.9 x 15.2 x 15.8 in, this is the shortest and narrowest body of the five. Mojgar states 100 lbs of ice per day with the first batch in 10 to 18 minutes, and the listing describes a three-step setup with a 1/2-inch male threaded faucet fitting and a drain hose. There is a one-touch self-clean button on the panel, which handles the internal water system rinse. The compressor is described as R290, which the brand pairs with an energy-efficiency claim. What is missing matters: there is no warranty term in the specification block, and no ETL certification claim in the feature list. Against the EUHOMY, the Mojgar gives up the printed warranty and the bigger bin in exchange for less weight and a narrower body. Against the ICEPURE it gives up the Wi-Fi and the drain pump.

Pros:

• Lightest unit in the set at 42.3 lb
• Narrowest body at 15.2 in
• 100 lbs / 24 h production claim
• One-touch self-clean function

Cons:

• No warranty term listed on the specification block
• No ETL claim in the feature list
• Requires a drain hose connection

3. COTLIN HXSeries — Best premium

The COTLIN HXSeries is the only drainless pick here, which is what to buy when your kitchen has no floor drain and you are not running a new one.

Best for: a finished kitchen with no drain plumbing under the cabinet Skip it if: you want the highest stated daily output

At 33.8 x 18.4 x 14.8 in and 62 lb, this unit ships in brushed stainless and makes crescent-shape ice. COTLIN pitches the drainless design as the reason you can install it without a plumber, and the listing carries an ETL certification claim. A one-touch switch starts the cycle with no menus to walk through. The premium price position buys you the drainless plumbing story and a specific ice shape, not raw throughput: the daily output figure is not stated on the specification block, unlike the other four. That is the trade-off worth naming. Compared with the EUHOMY, you lose the 33 lb bin and the published warranty, and you gain the freedom to install anywhere. Compared with the ICEPURE at a similar price position, you swap the drain pump and Wi-Fi for the drainless architecture and a simpler control panel.

Pros:

• Only drainless pick in the set
• Crescent ice shape suited to cocktails
• Brushed stainless finish
• ETL certification claim from COTLIN
• One-touch start with no menus

Cons:

• No daily output figure on the specification block
• Highest price position with no output figure to justify it
• Not the smallest footprint despite the premium tag

4. ICEPURE YD-QZ001 — Best for heavy use

The ICEPURE YD-QZ001 is the pick for a home bar that runs on a schedule, because it is the only unit here with a drain pump and Wi-Fi app control built in.

Best for: a home bar you want to schedule from your phone Skip it if: your Wi-Fi does not reach the cabinet

Dimensions land at 33.9 x 18.7 x 15 in and 62 lb. ICEPURE claims 90 lb per day with 40 cubes per 10 to 18 minute cycle and a 26 lb storage bin. The drain pump matters: with a pump on board, the drain line can travel up to a sink cabinet rather than needing gravity to a floor drain, which is what makes this the pick for a retrofit into a kitchen island or a basement bar. The Wi-Fi app handles ice-thickness settings, start-stop and a 24-hour timer, and the listing describes ice-full and low-water alerts. A built-in activated carbon filter is mentioned for chlorine, sediment and off-tastes. The trade-off is a smaller bin than the EUHOMY (26 lb versus 33 lb) and no published warranty term on the specification block.

Pros:

• Only pick with a drain pump included
• Wi-Fi app control with 24-hour timer
• Built-in activated carbon water filter
• Ice-full and low-water alerts
• Auto-clean function

Cons:

• 26 lb bin, smaller than the EUHOMY's 33 lb
• No warranty term on the specification block
• 90 lb / day production is the lowest quoted here

5. COSTWAY EP25962US — Best for beginners

The COSTWAY EP25962US is the friendliest first-time buy in the set, thanks to a reversible door hinge that adapts to almost any cabinet layout.

Best for: a first-time buyer who is not sure which side the door should open Skip it if: your rough opening is under 15 in wide

The COSTWAY measures 33.5 x 20.3 x 15 in and weighs 56.8 lb. The daily output claim is the highest in the set at 110 lbs / 24 h, with 40 cubes every 12 to 15 minutes. Three thickness modes on the panel run from 12 minutes for a thin cube up to 15 minutes for a thicker one. What sets this pick apart is the reversible-door hinge: left-side or right-side, whichever the cabinet demands, which is a genuine kindness on a first install. The automatic cleaning function walks the pump through three intermittent rinses when you hold the button for two seconds. Against the EUHOMY, the COSTWAY gives up the printed warranty term and the 33 lb bin. Against the Mojgar, it adds the reversible door and the higher output claim, but adds weight and depth as well.

Pros:

• Highest daily output claim at 110 lbs / 24 h
• Reversible door hinge for left or right install
• Three adjustable ice-thickness modes
• Automatic cleaning cycle with one-button start

Cons:

• Deepest body in the set at 20.3 in
• No warranty term on the specification block
• Slowest seller of the five here

The one spec most buyers miss: drainage

Most guides to the best small undercounter ice maker compare daily output, and daily output is the wrong place to start. Every unit in this set claims between 90 and 110 lb per day, and the differences among them get lost against a household's actual usage of maybe 5 to 15 lb a day. What actually decides the buy is drainage, because the plumbing under your cabinet decides whether a unit can be installed at all.

Three approaches show up in the five picks:

1. Gravity drain, as on the EUHOMY IM-02. Needs a floor drain or a drain outlet below the ice maker. Cheapest to build, but restrictive if you are retrofitting.
2. Drain line with a hose, as on the Mojgar CIM-360F and the COSTWAY EP25962US. Better than gravity because the line can travel a short distance, but still needs somewhere for the water to go without an internal pump.
3. Drain pump, as on the ICEPURE YD-QZ001. The pump lifts wastewater up and out to a sink drain, which is what makes an island install or a basement bar practical.
4. Drainless, as on the COTLIN HXSeries. No drain line at all. The ice melts back into the reservoir and is recycled, which trades some efficiency for the ability to install anywhere with just a water inlet.

Decide drainage first, then compare output figures.

Will it actually fit your cabinet opening?

A 15-inch cutout is not the same as a 15-inch cabinet opening, and the specification lists here mix width figures across the body and the door. Measure the rough opening at three heights, front to back and side to side, before you commit.

• The COTLIN HXSeries lists 14.8 in as body width, the narrowest of the five
• The ICEPURE YD-QZ001 lists 15 in
• The COSTWAY EP25962US lists 15 in
• The Mojgar CIM-360F lists 15.2 in
• The EUHOMY IM-02 lists 17.5 in in the body specification, which is wider than a 15 in nominal opening

Height is also worth checking. The COTLIN, COSTWAY, ICEPURE and Mojgar all sit close to 34 inches tall, which slots under a standard 36 inch counter with clearance for the water line at the back. The EUHOMY is 31.3 in tall.

How much ice does a household really need?

Here is the trick with output claims: 100 lbs of ice per 24 hours is the machine's ceiling under ideal conditions, and a real household nowhere near hits it. A big dinner party might use 20 lb of ice. A daily cocktail hour for two people uses 2 to 4 lb. The stated ceiling matters as headroom, not as a target.

That reshapes the comparison. The ICEPURE at 90 lb / day and the EUHOMY at 100 lbs / 24 h are, for most households, equivalent on capacity, and the decision shifts to bin size and drainage. Bin capacity is what constrains a party: once the bin is full, the machine stops until you empty it. The EUHOMY's 33 lb bin buys a longer runway than the ICEPURE's 26 lb bin, which is why the EUHOMY holds the overall pick despite the lower headline output claim from the COSTWAY.

What about the word small in the keyword?

The word small in the search does not narrow this category as tightly as it looks. Every pick here is a 15-inch class built-in, which is small compared with a full undercounter refrigerator but not small compared with a countertop portable ice maker. If your budget or your space rules out a built-in entirely, none of these five is the right buy for you. In practice, the best small undercounter ice maker is defined by fitting a 15-inch cabinet opening, weighing under 70 lb, and standing under 34 inches tall, and each of these five clears the bar.

The verdict

If you have a floor drain or a drain outlet under the cabinet, the EUHOMY IM-02 is the best small undercounter ice maker in this set. It gives you the 33 lb bin, the 100 lbs / 24 h production claim, an ETL certification claim, and the only 1-year manufacturer warranty printed on the specification block. That last point matters more than it looks, because a warranty term you can read is a warranty term you can enforce.

If you are retrofitting into a kitchen that has no drain plumbing under the cabinet, the winner flips. The COTLIN HXSeries is the drainless pick, and the drainless design is what makes the install possible without a plumber. The cutoff is simple: drain outlet nearby, buy the EUHOMY; no drain outlet, buy the COTLIN.

The ICEPURE takes third if you want a drain pump so the wastewater can travel uphill to a sink, and the Wi-Fi app is the runner-up's exact advantage. The Mojgar is the budget-first choice for the tightest cabinet, and the COSTWAY is the friendliest first install because of the reversible door.

FAQ

What size counts as a small undercounter ice maker?

What size counts as small is a 15-inch class built-in, which fits a 15 in nominal cabinet cutout, stands under 34 inches tall, and weighs under 70 lb. Every pick in this guide sits inside that envelope. Countertop portable units are smaller still but do not install under a counter, so they fall outside the category the keyword names.

Is a drainless ice maker worth the premium?

A drainless ice maker is worth the premium when your kitchen has no floor drain and no drain line reaching the cabinet, because the alternative is hiring a plumber. The COTLIN HXSeries is the drainless pick here. It gives up a stated daily output figure and sits in the premium price position, so the value is entirely about installation freedom.

How much ice per day does a home bar really need?

How much ice per day a home bar really needs is 5 to 15 lb for daily use and 20 to 30 lb for a party of a dozen guests. Every unit here claims 90 lb or more per 24 hours, so the ceiling is not the constraint. Bin capacity is: the EUHOMY holds 33 lb, the ICEPURE holds 26 lb, and that gap decides how long a party runs before you refill.

EUHOMY IM-02 vs COTLIN HXSeries: which should I buy?

EUHOMY IM-02 vs COTLIN HXSeries comes down to drainage. Buy the EUHOMY if you have a floor drain or a gravity outlet under the cabinet, because it adds a 33 lb bin, a printed 1-year warranty, and a 100 lbs / 24 h output claim. Buy the COTLIN if you have no drain plumbing at all, because it is the only drainless pick in the set.

What is the biggest mistake buyers make in this category?

The biggest mistake buyers make in this category is comparing daily output figures first and drainage last. Output claims cluster between 90 and 110 lb per 24 hours across every pick here, so the difference is small. Drainage decides whether the unit installs at all: gravity, drain line, drain pump or drainless. Sort your picks by drainage before you read any output figure.

Start with the tape measure and a flashlight under the sink cabinet. Note the opening width at floor level, the height to the underside of the counter, and where the nearest drain outlet sits, if there is one. Those three answers point you to one of the five picks without much argument left. The EUHOMY IM-02 is the right default for a kitchen that already has the plumbing, because it pairs the biggest bin in the set with the only printed warranty, and those are the two things you cannot add later. Everything else on the specification block, you can work around.
