Buyer’s Guide: How to Choose the Right Built-In Ice Maker

Choosing the perfect built-in ice maker involves balancing your ice preferences, daily usage needs, and installation constraints. This guide will walk you through the most important factors to consider, empowering you to match a machine to your home and lifestyle.

• Drain Type: Pump vs. Gravity vs. Drainless
  This is the most critical technical decision you’ll make. A gravity drain is the simplest mechanically but requires a floor drain to be located directly below the unit’s drain outlet. A drain pump offers maximum installation flexibility, as it actively pushes meltwater up and away, allowing you to connect the drain line to a nearby sink. Drainless models are the easiest to install because they function like freezers and produce no meltwater, but they make ice more slowly and the ice is opaque.

• Ice Type & Quality: Clear vs. Crescent
  The type of ice you want dictates the type of machine you need. Clear ice (cubes or bullets) is dense, pure, and melts slowly, making it the ideal choice for high-end cocktails and spirits as it won’t water down your drink. Crescent ice is a versatile, cloudy ice shape common in drainless and refrigerator models. It cools drinks effectively and its shape prevents it from clumping, but it melts faster than clear ice.

• Daily Ice Production
  Be realistic about how much ice you’ll actually use. A smaller 12 lb/day model like the Whynter is perfectly sufficient for a couple or for casual use. A mid-range 50 lb/day machine is great for a family or for moderate entertaining. A high-capacity 90 lb/day machine like the EUHOMY models is best for large families, avid entertainers, or for regularly filling coolers.

• Storage Bin Capacity
  Daily production doesn’t matter if the storage bin is always full and the machine has shut off. A small 6 lb bin is fine for light use but will empty quickly during a party. A larger 24-26 lb bin acts as a generous reservoir, ensuring you have a large quantity of ice on hand at a moment’s notice. Remember that in clear ice makers, this ice is slowly melting and being replenished.

• Installation Space & Ventilation
  Always measure your cabinet cutout’s width, depth, and height before you buy. Most undercounter models are designed for a 15-inch wide opening, but depths can vary. Crucially, you must choose a front-venting model for any true built-in application. This allows the machine to be installed flush with your cabinetry because it pulls in and pushes out air from the front, requiring no side or rear clearance.

• Maintenance & Cleaning
  To ensure your ice always tastes fresh and your machine runs for years, look for models with a self-cleaning cycle. This invaluable feature automates the descaling process, which is necessary to remove mineral buildup from your water supply. It’s a huge time-saver. Models that also include an integrated water filter provide an extra layer of protection against scale and impurities.

FAQs About Built-In Ice Makers

Do built-in ice makers need a drain?

Yes, most clear ice makers require a drain, but drainless options exist. Clear ice makers work by constantly circulating water over a freezing plate, and this process requires them to purge mineral-heavy water. This wastewater must go somewhere, requiring either a gravity drain (to a floor drain) or a drain pump (to a sink drain). However, “drainless” models like the COTLIN and Whynter are essentially freezers that keep ice frozen solid, so they produce no meltwater and do not need a drain.

Do built-in ice makers keep ice frozen?

It depends on the type. Clear ice makers, like the EUHOMY and spray-tech COTLIN models, have insulated but not sub-freezing storage bins. The ice is meant to slowly melt, which gets drained away, and the machine replenishes it with fresh ice. This keeps the ice from clumping. In contrast, drainless models like the Whynter UIM-155 are true freezers that maintain sub-freezing temperatures to keep the ice solid indefinitely.

What is the difference between clear ice and crescent ice?

Clear ice is dense and slow-melting, while crescent ice is cloudy and melts faster. Clear ice is made by flowing water over a super-chilled plate, a process that freezes the water in layers and pushes out trapped air and impurities. This results in a nearly pure, dense cube or bullet. Crescent ice is made in a tray mold, similar to a refrigerator’s ice maker. This method traps air, which makes the ice cloudy and less dense.

How much ice does a built-in ice maker make?

Production capacity varies widely, from 12 lbs to over 90 lbs per day. Compact models designed for light use, like the Whynter UIM-155, may produce only 12 lbs in a 24-hour period. Standard home models for families and entertainers typically produce around 50-60 lbs per day. High-capacity and commercial-style units, like the EUHOMY models, can produce 90 lbs or more, making them suitable for very high-demand situations.

How do I clean a built-in ice maker?

Use the self-cleaning cycle if available; otherwise, clean it manually. For modern units with a one-touch self-cleaning function, you simply add a bottle of approved ice machine cleaning solution to the water reservoir and activate the cycle. The machine does the rest. For models without this feature, you will need to manually scrub the interior with a soft cloth and a solution of water and vinegar or a nickel-safe cleaner, following the manufacturer’s instructions.

Can I adjust the ice cube size?

Yes, some advanced models allow for adjustable ice thickness. Premium ice makers, like the EUHOMY units I reviewed, feature a smart control panel that lets you increase or decrease the ice-making cycle time. A longer cycle allows more water to freeze, resulting in a thicker, larger ice cube. A shorter cycle produces smaller, thinner cubes. This is a high-end feature not found on basic or drainless models.

What is a panel-ready ice maker?

A panel-ready ice maker is designed to accept a custom cabinet panel. This allows the appliance to blend in seamlessly with your kitchen’s cabinetry for a fully integrated, high-end look. You provide a panel and handle that match your cabinets, which is then mounted to the front of the ice maker. The models I reviewed all feature stainless steel doors and are not panel-ready.

Is a built-in ice maker noisy?

You can expect some operational noise, similar to a refrigerator. You will hear the gentle hum of the compressor and fan, the sound of water circulating, and the clatter of ice dropping into the bin during the harvest cycle. Drainless models tend to be quieter as they operate more like a standard freezer. High-capacity clear ice makers can be louder, especially when the compressor is running and ice is being produced.

What is a drain pump and do I need one?

A drain pump is an electric pump that actively pushes meltwater out, and you need one if you don’t have a floor drain. If your ice maker is not located directly above a floor drain, a standard gravity drain won’t work. The drain pump gives you the flexibility to install the unit almost anywhere (like a kitchen island) and connect its drain line to a more distant or higher drain, such as a sink’s garbage disposal.

How often should I clean my ice maker?

It’s best to clean your ice maker every 3 to 6 months. Regular cleaning prevents the buildup of scale and minerals from your water supply, which can affect performance, damage components, and make your ice taste bad. If you live in an area with hard water, you may need to clean it more frequently. Always follow the manufacturer’s cleaning instructions and use an approved nickel-safe cleaning solution.

My Final Verdict on the Best Built-In Ice Maker

After weeks of analysis and comparing every feature, it’s clear that the best built-in ice maker is the one that best balances your desire for high-quality ice against the practical realities of your home’s installation options. While every model on this list is a strong performer in its category, one stands out for its ability to meet the needs of the widest range of users without compromise.

My final recommendation is the EUHOMY Under Counter Ice Maker with Drain Pump. It is the best overall choice due to its powerful combination of massive ice production, high-quality clear ice, and, most importantly, the unmatched installation flexibility provided by its built-in drain pump. This single feature is a game-changer, solving the most common and expensive installation headache.

This ice maker is perfect for you if…
