Quick Answer: For a permanently plumbed wet bar, the EdgeStar IB450SSP (about $1,419-1,489) is the best built-in ice maker — a front-venting, 15-inch cabinet-ready unit with a built-in drain pump that makes up to 50 lbs of clear cubed ice a day, replacing EdgeStar’s now-discontinued IB250SS. If the bar isn’t plumbed, or you’re renting and can’t touch the cabinetry, the GE Profile Opal 2.0 (about $449) is the better fit — it sits on the bar top, needs only an outlet, and makes about 38 lbs a day of the chewable nugget ice that’s become the standard pour for muddled cocktails. The decision that matters most isn’t brand, it’s whether the bar has a water line: that single fact decides which class of machine you’re shopping.
A wet bar is a plumbing decision wearing a furniture question. The cabinet, the countertop material, the layout — all secondary to one fact: does this bar have a water line, and can it get a drain? Get that answer first, because it eliminates half the market before you compare a single spec sheet.

1. EdgeStar IB450SSP — Best Built-In Wet Bar Ice Maker
EdgeStar IB450SSP Built-In Ice Maker
- Front-venting build means it can go fully enclosed in a bar cabinet without overheating — most undercounter units can't say that.
- Up to 50 lbs of clear, restaurant-style cubed ice a day per EdgeStar's current spec sheet, with about 25 lbs of storage — nearly double the output of the discontinued IB250SS it replaces.
- Built-in drain pump handles its own drainage, so it doesn't need a separate condensate pump or gravity setup, though it still needs a drain point somewhere to pump to.
- Stainless finish reads as a built-in appliance rather than a countertop gadget bolted into cabinetry — the look most wet bar owners are actually paying for.
If the bar is getting a real water line during a remodel, this is the default. It replaces EdgeStar’s prior IB250SS, which has been discontinued and is now only findable through secondary sellers — the IB450SSP is the current production model, per EdgeStar’s own 2026 lineup. Its own built-in pump means you don’t need to separately plan for gravity drainage or add a condensate pump, one less install headache than older built-ins that ship without one.

2. Whynter UIM-155 — Best Drainless Built-In
Whynter UIM-155 Built-In Ice Maker
- Only built-in on this list that skips the drain question entirely — a water line and an outlet is the whole install.
- About 12 lbs of bullet ice a day and roughly 6 lbs of storage, sized for a bar that sees weekend use, not nightly volume.
- Compact footprint suits a smaller wet bar cabinet where the EdgeStar's dimensions won't fit.
- Roughly half the EdgeStar's price for a genuinely simpler remodel — the trade is output, not build quality.
Choose this over the EdgeStar when the bar can get a water line but adding a drain isn’t realistic — a finished basement wet bar with no floor drain nearby is the classic case. The 12 lbs/day ceiling is real, so it fits occasional entertaining better than a bar that runs every night.
3. NewAir ClearIce40 — Best Output-Per-Dollar
NewAir ClearIce40 Undercounter Ice Maker
- About 40 lbs a day of clear cube ice — more than triple the Whynter's output at roughly half the EdgeStar's price.
- Needs both a water line and a drain (gravity or pump), so it only makes sense when the remodel already has plumbing access planned.
- Clear cubes melt slower than bullet or crescent ice, which matters for a bar pouring spirit-forward drinks that shouldn't dilute fast.
- Same 15-inch built-in width as the EdgeStar, so it's a drop-in swap if the cabinet is already sized for that footprint.
If the contractor is already running a drain line for a bar sink, adding one more line for this machine is a rounding error — and the output-per-dollar here beats every other built-in on this list. Skip it only if a floor drain genuinely isn’t in the plan.
4. GE Profile Opal 2.0 — Best for an Unplumbed Bar Top
GE Profile Opal 2.0 Nugget Ice Maker
- Sits on the bar top instead of inside cabinetry, so there's zero plumbing question — it just needs an outlet.
- Nugget ice is the format bartenders reach for in muddled cocktails and mint juleps, per common bar-industry practice, because the soft pellets pack a glass fast without watering down a pour as quickly as cube ice does.
- About 38 lbs a day per GE's specs, with app scheduling so a batch is ready before guests arrive.
- Drainless side tank needs manual topping up, the one ongoing chore against a plumbed built-in.
Rented condo, finished basement with no water access, or just not ready to remodel a cabinet — the Opal solves the wet bar’s cocktail-ice problem without touching plumbing at all. Full ownership details are in our GE Opal 2.0 review.
5. Silonn SLIM21 — Best Budget Bar-Top Pick
Silonn SLIM21 Countertop Ice Maker
- About 26 lbs of bullet ice a day for well under $100 — the entry point if the Opal's price is the blocker, not the plumbing.
- Slim profile fits a narrow bar top without crowding glassware and bottles.
- Bullet ice is a reasonable stand-in for nugget in most mixed drinks, just less soft and chewable.
- Drainless and hand-filled, identical install simplicity to the Opal at a fraction of the cost.
For a casual home bar that just needs cold drinks rather than a specific ice texture, this is the value pick — the same unplumbed simplicity as the Opal at roughly a fifth of the price.
Built-in vs. bar-top: the one question that decides it
| Your bar has... | Go with | Why |
|---|---|---|
| Water line + drain already planned | NewAir ClearIce40 | Highest output-per-dollar once plumbing is a sunk cost |
| Water line, no drain access | Whynter UIM-155 | Drainless freezer-style design skips the drain requirement entirely |
| No plumbing, permanent bar-top spot | GE Opal 2.0 | Best cocktail-specific ice, no remodel needed |
| No plumbing, tight budget | Silonn SLIM21 | Same drainless simplicity for a fraction of the Opal's price |
Only a built-in-rated, front-venting unit is safe to enclose in cabinetry — a countertop machine boxed into a cabinet will overheat, because it’s designed to vent from the sides and back into open air. That’s the single most common wet bar install mistake: buying a countertop unit for the ice type, then having a cabinetmaker box it in anyway.
Wet bar ice makers by the numbers
| Metric | Figure | Why it matters |
|---|---|---|
| Built-in cabinet width | 15 inches | The standard undercounter footprint (EdgeStar IB450SSP, NewAir ClearIce40) most bar cabinetry is designed around. |
| Fully drainless output | ~12 lbs/day | What the Whynter UIM-155, the only truly drainless built-in here, produces without needing any drain line during the remodel. |
| Plumbed + drain output | 40-50 lbs/day | What the NewAir ClearIce40 and EdgeStar IB450SSP add once a drain (external or self-pumped) is part of the plan — over 3x the drainless Whynter's output. |
| Bagged-ice cost, regular entertaining | $15-25/month | Typical spend for a household hosting weekly gatherings, per common $2-4 per 10-lb bag retail pricing — a built-in machine pays that back within a season. |
| Bar-top output | 26-38 lbs/day | What unplumbed countertop machines (Silonn, GE Opal) deliver for a bar with no water access. |
The bottom line
If the wet bar is getting real plumbing during a build, the EdgeStar IB450SSP (about $1,419-1,489) is the built-in to buy — front-venting, cabinet-ready, with its own built-in drain pump and up to 50 lbs/day of output. Already running a drain line for a bar sink and want to spend less? The NewAir ClearIce40 (about $300) gets close to the same output for a fifth of the price, without the self-pumping convenience. No water access at all, or renting and can’t touch the cabinetry? The GE Profile Opal 2.0 (about $449) delivers the nugget ice a home bar actually wants without a single plumbing decision, or step down to the Silonn SLIM21 (about $69-90) if budget matters more than ice texture. Whichever you pick, never box an unrated countertop machine into cabinetry — check for “built-in” or “front-venting” on the spec sheet before the cabinetmaker measures anything.

Last updated: August 30, 2026 — corrected a discontinued-model error: EdgeStar’s IB250SS has been discontinued and is no longer sold new, replaced across this guide with the current-production EdgeStar IB450SSP (up to 50 lbs/day, built-in drain pump, about $1,419-1,489, per 2026 Home Depot pricing) — a real spec and price change, not just a naming swap. The IB450SSP is not fully drainless like the Whynter UIM-155; it handles its own drainage with a built-in pump rather than needing a separate one.
