If you want more ice than your freezer tray can keep up with, you have two very different machines to choose from: a portable countertop ice maker that sits on the counter and needs no plumbing, or a built-in (undercounter) ice maker that is plumbed in like an appliance. For a small home or a rental, the right answer is usually clear once you weigh installation, storage and cost. Here is the full comparison.
Countertop vs Built-In at a Glance
| Factor | Countertop ice maker | Built-in (undercounter) |
|---|---|---|
| Installation | None—plug in and fill the reservoir | Needs a water line and drainage |
| Ice storage | Insulated basket; ice slowly melts | Keeps ice frozen in a cold bin |
| Capacity | Small batches; refill the tank | Larger, continuous supply |
| Footprint | Sits on the counter; can be put away | Permanent cabinet space |
| Cost | Budget-friendly | Significantly more, plus install |
| Renter-friendly | Yes—moves with you | No—it is a fixture |
Countertop Ice Makers: The Small-Home Default
A countertop ice maker is the pragmatic pick for most apartments and small houses. You plug it in, pour water into the reservoir, and it produces the first batch of ice in well under ten minutes. There is no plumber, no permanent commitment, and you can store it in a cabinet when you do not need it—then bring it back out for guests or summer.
The one thing to understand is storage: most countertop units hold finished ice in an insulated basket, not a refrigerated bin, so the ice gradually melts (many recycle the meltwater into the next batch). That is fine for daily drinks and entertaining—you make ice as you need it—but it is not long-term frozen storage. We explain this fully in does a countertop ice maker keep ice frozen?

Built-In Ice Makers: Convenient, but a Commitment
A built-in or undercounter ice maker is what you picture in a home bar: it is plumbed to a water line, drains automatically, makes ice continuously, and stores it in a cold bin so it stays frozen and ready. For a household that goes through a lot of ice and has the space, it is genuinely convenient and looks seamless under the counter.
The catches are real for a small home. It requires a nearby water supply and drainage, permanent cabinet space, and professional installation, and both the unit and the install cost far more than a countertop model. For a renter, it is usually a non-starter—you cannot take it with you, and most landlords will not approve the plumbing.
Which Is Right for a Small Home?
Choose a countertop ice maker if you rent, have limited space, want to avoid plumbing and spend less, and are happy making ice on demand rather than storing it frozen. This fits the vast majority of apartments and small kitchens.
Choose a built-in ice maker if you own your home, have a spot with water and drainage, use a high volume of ice regularly, and want a permanent, always-stocked supply with a seamless look.
Questions to Answer Before You Buy
- Do you have plumbing and drainage where the machine would go? If not, countertop is the realistic option.
- Do you rent? A countertop unit moves with you; a built-in does not.
- How much ice do you actually use? Daily drinks suit countertop; constant high volume favors built-in.
- Which ice do you like? If you prefer soft, chewable nugget ice, compare it with standard bullet ice in nugget vs bullet ice makers.
Frequently Asked Questions
Is a countertop ice maker as good as a built-in?
For most small homes, yes—it makes ice quickly with no installation. The main difference is that a built-in keeps ice frozen in a cold bin, while a countertop basket lets ice slowly melt, so you make it on demand.
Do built-in ice makers need plumbing?
Yes. They connect to a water line and require drainage, which is why they need permanent placement and professional installation—and why they do not suit renters.
Why does my countertop ice maker’s ice melt?
Because the storage basket is insulated, not refrigerated. The machine keeps making ice as needed; transfer any surplus to your freezer if you want to store it.
Which is cheaper, countertop or built-in?
A countertop ice maker is far cheaper to buy and needs no installation. A built-in costs more up front and adds plumbing and installation costs.
