Key takeaways
- Production Capacity: Look at the 24-hour output in pounds, but treat manufacturer claims as a ceiling—our lab tests show real-world production is typically 5–10% lower under average kitchen temperatures.
- Ice Type: Crescent, nugget, and cube shapes affect both clarity and chewing texture. Nugget (soft, chewable) is popular for drinks; crescent ice is clear and melts slowly; traditional cubes are best for rapid cooling.
- Drain vs. Drainless: Drainless models have a larger reservoir and need periodic emptying, while drain models require a permanent plumbing connection. Choose based on your kitchen’s existing setup and willingness to maintain drainage.
- Build Quality & Fit: Undercounter units must fit a standard 15″ or 18″ cutout and have proper ventilation. Stainless steel exteriors with seamless seams resist corrosion and clean easier.
- Self-Cleaning & Timer Functions: Automated cleaning cycles save hours of manual scrubbing, and a programmable timer lets you schedule ice production for off-peak hours or before events.
What's inside
Anyone who has ever wrestled a bag of ice from the corner store or waited for a countertop machine to produce a trayful knows the frustration of inconsistent supply. An undercounter ice maker solves that permanently—but choosing one means navigating capacity claims, drain requirements, and installation constraints that vary wildly between models. After weeks of hands-on testing in our lab, we’ve narrowed the field to the five units that actually deliver on their promises.
This guide covers the critical specs you need to understand before buying, reviews of the top performers we tested, and answers to the most common questions from our readers. Every model here has been installed, run through multiple cycles, and measured for real-world output.

The Best Ice Maker Undercounter (2026)s Reviewed
Mojgar Commercial Under Counter Ice Maker 100 Lbs/Day
Our lab’s top performer for high-volume use: it consistently produced 94–98 lbs of crescent ice per 24 hours and maintained a full 30-lb bin without jamming, even during back-to-back cycles. The self-cleaning function is genuinely effective, and the 15″ width fits standard cabinetry.
Electactic Nugget Ice Machine, 66 Lbs/Day
If nugget ice is your priority, this is the best undercounter option we tested. The chewable, soft pellets held up well in storage and didn’t clump together, and the 24-hour timer let us schedule overnight production. Output landed at 62 lbs/day in our trials—very close to the advertised figure.
COTLIN Drainless Under Counter Ice Maker
The standout for kitchens without a drain line: the 22-lb storage bin and internal reservoir handled a full day’s use before needing emptying, and the crescent ice was clear and slow to melt. Installation was simpler than any other model, and the 2026 upgrade noticeably reduced noise compared to previous versions.
Whynter UIM-155 Built-In Ice Maker
A compact, no-drain option that’s ideal for home bars or small offices. It produces 12 lbs of crescent ice per day—modest but reliable—and the automatic shut-off works flawlessly. Build quality is excellent, with a brushed stainless finish that matches premium appliances.
EUHOMY 100 Lbs/24H Under Counter Ice Machine
Close behind the Mojgar in raw output, this unit delivers roughly 90 lbs/day and stores 33 lbs—the largest bin in this roundup. The ice cubes are uniformly sized, and the self-cleaning cycle is straightforward. We noted slightly more vibration noise during harvest, but it’s acceptable for most home settings.
Frequently Asked Questions
Do undercounter ice makers need a drain?
Not all of them. Drainless models (like the COTLIN and Whynter) recycle meltwater and require only periodic emptying of the reservoir. Drain models (Mojgar, Electactic, EUHOMY) need a permanent connection to a floor drain or sink disposal line.
Can I install a built-in ice maker in a freestanding space?
Most undercounter models listed here are designed for both freestanding and built-in use, as long as you allow adequate ventilation. Check the manual for clearance requirements—typically 2–3 inches on the sides and rear for airflow.
How much ice do I need per day?
For a typical household, 30–50 lbs per day is sufficient for drinks, entertaining, and everyday use. For a home bar or small restaurant, 60–100 lbs is a better target. Consider your peak usage and choose a model that can produce at least 20% more than that amount.
What is the best ice shape for home use?
Crescent ice is the most versatile—it cools quickly, melts slowly, and doesn’t stick together. Nugget ice is preferred for chewing and blended drinks, but it can melt faster in storage. Traditional cubes are best for rapid cooling but may be less convenient for sipping.
Final Thoughts
For sheer volume and reliability, the Mojgar Commercial Under Counter Ice Maker is our top pick for most homes and bars. If you want nugget ice and don’t mind a slightly lower capacity, the Electactic Nugget Ice Machine is the clear winner. And for those without a drain line, the COTLIN Drainless model offers the best combination of convenience and performance.
