For most homes that want nugget ice, our top pick is the GE Profile Opal 2.0. Important to know up front: the Opal is a countertop (freestanding) nugget ice maker, not a built-in plumbed unit. It sits on the counter, recirculates its own melt water so it needs no drain line, produces nugget ice, and has a self-cleaning cycle. If you specifically need a true built-in undercounter model that plumbs into a water supply and drain, that is a separate category we cover in the buying guide below. We compared top models across key specs to help you choose.
These models range in daily output and bin capacity. Built-in undercounter units plumb into a drain line; countertop nugget makers like the Opal recirculate their melt water and need no drain. The best overall balances ice type, production speed, and reliability.

Undercounter Ice Maker Buying Guide
Ice Type
Nugget ice is soft and chewable, great for drinks and chewing. Bullet ice is hard and clear, melts slower. Cube ice is traditional but requires larger units. Choose based on your preference.
Production and Storage
Daily output ranges from 25 to 50 lbs. Bin capacity matters: larger bins (3+ lbs) let you store more ice, but ice can melt and refreeze into a block if left too long. Most units produce 8-12 ice cubes per cycle.
Installation and Maintenance
True built-in undercounter units require a drain line (gravity or pump) and a water supply line. Countertop nugget makers like the GE Profile Opal recirculate their melt water, so they need no drain and you simply refill the reservoir. Self-cleaning cycles reduce buildup. Stainless steel interiors resist mold better than plastic.
Safety Notes
- Ensure proper ventilation around the unit to prevent overheating.
- Use a dedicated GFCI outlet near water sources.
- Do not block the drain line; check for kinks.
- Clean the unit regularly to prevent mold and bacteria growth.
What to Avoid
- Avoid models with plastic ice chutes that can crack in freezing temperatures.
- Avoid units with poor insulation that cause ice melting and refreezing.
- Avoid buying a model without a self-cleaning cycle if you plan heavy use.
- Avoid units that require a pump drain if your setup has a gravity drain available.
FAQ
Do undercounter ice makers need a drain?
It depends on the type. True built-in undercounter units require a drain line (usually gravity, sometimes a pump) to remove wastewater. Countertop nugget makers like the GE Profile Opal recirculate their melt water and need no drain, though they are not built-in units.
How much ice does an undercounter ice maker produce per day?
Typical output ranges from 25 to 50 lbs per day, depending on the model and ambient temperature.
Can I install an undercounter ice maker myself?
If you have basic plumbing and electrical skills, yes. You need a water line and drain line. Some models require a dedicated electrical circuit.
Final Verdict
The GE Profile Opal 2.0 is the best pick for most homes that want nugget ice without plumbing, thanks to its self-cleaning cycle and smart features. It is a countertop unit rather than a built-in undercounter model. The NewAir AI-200R offers great value for bullet ice lovers, and the Costway EP24781 is a solid budget pick. Avoid models with plastic internals and limited ventilation.
