The best built in ice maker for most homes is the GE Profile Opal 2.0 Nugget Ice Maker because it produces soft, chewable nugget ice and fits under a standard counter.

Built In Ice Maker Buying Guide
Ice Type: Nugget vs Clear Cube vs Flake
Nugget ice (Sonic-style) is soft and chewable, ideal for soft drinks and smoothies. Clear cubes are dense and slow-melting, perfect for cocktails and whiskey. Flake ice is soft and molds easily, often used in healthcare or seafood displays. Most home users prefer nugget or clear cube. Nugget machines tend to be smaller and more affordable, while clear cube machines require more power and a drain.
Production Rate and Storage
Production is measured in pounds per day (24-120 lbs/day is typical). Storage capacity (2-28 lbs) matters for how often you need to empty the bin. For a family, aim for at least 50 lbs/day production and 20+ lbs storage. Note that production rate depends on ambient temperature and water temperature; warmer conditions reduce output.
Installation: Water Line and Drain
Most built in ice makers require a cold water line (1/4 inch copper or plastic tubing) and a drain line. Some models are self-contained and use a built-in reservoir that needs manual filling, but those are not truly built-in. Clear cube machines typically need a drain to remove melt water. Nugget machines often have a self-contained bin that recirculates melt water, reducing plumbing needs. Check if a drain pump is required if the drain is above the unit.
Safety Notes
- Always follow manufacturer’s instructions for water line connection to prevent leaks.
- Use a water filter to reduce mineral buildup and improve ice quality.
- Ensure proper ventilation (usually 3-5 inches clearance behind unit) to prevent overheating.
- Unplug before cleaning to avoid electrical shock.
What to Avoid
- HomeHaven Built In Ice Maker: unreliable compressor, ice clumps, and poor customer service.
- Cuisinart ICE-100: not truly built-in, requires manual fill and drains into a bucket.
- KitchenAid KUIC10: expensive for the production rate; owners report noisy operation.
- Whynter UIM-155SS: ice tends to be cloudy and melts fast; drain line prone to clogging.
FAQ
Do I need a drain for a built in ice maker?
Most clear cube machines require a drain line. Nugget ice makers often have a self-contained bin that recirculates melt water, but some still recommend a drain. Always check the manual.
How much space do I need under the counter?
Standard undercounter width is 15 inches, but some models are 17 or 18 inches. Depth is typically 22-24 inches. Measure your space and allow for ventilation.
How often should I clean my ice maker?
Every 6 months for most models. Use a manufacturer-approved cleaner or a vinegar solution to remove mineral scale and mold.
Final Verdict
The GE Profile Opal 2.0 Nugget Ice Maker is the best built in ice maker for most people, offering soft nugget ice and easy undercounter installation. For clear cube enthusiasts, the Scotsman Prodigy Elite delivers restaurant-quality ice with a large storage capacity.
