U-Line Outdoor Ice Maker Guide: Crescent, Clear, or Nugget (2026)
Short answer: U-Line makes three outdoor ice types across four models. Crescent (OCR115) is the highest-production and lowest-maintenance pick. Clear cube (OCL115 gravity drain, OCP115 pump drain) is the cocktail-quality choice for premium bar zones. Nugget (ONP115) is the soft-chewable pick for iced tea, mixed drinks, and snacking. All four fit the standard 15-inch outdoor slot; the pump-drain models install without a floor drain.
U-Line's outdoor ice makers are the category leader — 60-90 lb/day production, 30-lb bin, marine-grade construction. But the model numbers are confusing and the pump-vs-gravity choice affects whether the unit fits your kitchen at all. Here's exactly what each does and how to pick.
The four current models
OCR115 — Crescent Ice (gravity drain) — $2,899. 90 lb/day production, 30-lb bin, half-moon crescent cubes ~5 grams each. Highest-production slot, hard-water tolerant, best general-purpose pick.
OCL115 — Clear Cube Ice (gravity drain) — $3,299. 60 lb/day production, 30-lb bin, 1x1x1-inch restaurant-quality clear cubes. Cocktail bar zones, whiskey rocks, premium presentation.
OCP115 — Clear Cube Ice (pump drain) — $3,599. Same ice type and production as OCL115 but with an internal condensate pump — installs anywhere, no floor drain needed. Retrofit and patio installs.
ONP115 — Nugget Ice (pump drain) — $3,999. 85 lb/day, 25-lb bin, chewable soft nugget (Sonic-style) ice. Iced tea, mixed drinks, families with kids, hospitality.
Ice type explained: which one is right?
Crescent (OCR115). Traditional half-moon ice, ~5 grams per piece. Most tolerant of hard water (mineral content shows less on the curved surface). Fastest production per hour, longest melt time in a glass. The default pick if you don't have a specific reason to go clear or nugget. Trade-off: not aesthetically premium — reads as standard freezer ice, not craft-bar ice.
Clear cube (OCL115 and OCP115). Restaurant-quality cube, 1x1x1 inch, near-perfect clarity. Made by directional freezing so trapped air escapes before the cube fully forms. Melts slowly (25-30% slower than crescent), doesn't dilute cocktails as fast. Trade-off: 30% lower production than crescent, shows mineral deposits if your water is hard (soften or filter recommended).
Nugget (ONP115). Soft, chewable, pellet-shaped ice — same style as Sonic Drive-In. Made by compacting flake ice into small nuggets. Absorbs drink flavors, extends drink volume, kids and iced-tea drinkers prefer it strongly. Trade-off: melts faster than any other ice type (10-15 minutes in a room-temp glass). Best for high-turnover pours, not for whiskey rocks.
Pump drain vs gravity drain — the install-critical choice
Gravity drain (OCR115 and OCL115). Ice maker sits above a floor drain within 8 feet, condensate water flows out by gravity through a 3/4-inch drain line sloped at least 1/4-inch per foot. Traditional install, no pump to maintain, quieter operation. Required: floor drain within reach. Most outdoor kitchens designed from scratch include one; retrofit patios usually don't. If your slab doesn't have a drain, gravity models can't install without cutting the slab.
Pump drain (OCP115 and ONP115). Ice maker has an internal condensate pump that lifts drain water up to 15 feet and away through a smaller-diameter line. Installs anywhere with just an electrical circuit and a water supply — no floor drain needed. Trade-off: pump adds $300-400 to the model price and a small maintenance point (pump can clog with mineral scale on hard water; annual descaling recommended). Worth it for any retrofit or slab-without-drain install.
Water supply requirements
Every U-Line outdoor ice maker needs a cold water line:
- Line size: 1/4-inch copper or PEX, standard refrigerator-style connection
- Water pressure: 20-100 psi (typical residential is 40-80, no booster needed)
- Water quality: standard tap water works; hard water (over 10 grains) benefits from an inline sediment + carbon filter
- Install a shutoff valve at the water supply for winterization and maintenance access
If your outdoor kitchen plans included plumbing, the ice maker line is easy to add. If not, running a new 1/4-inch line from an interior wall through the slab or foundation is a one-hour plumbing job.
Sizing: how much ice do you actually need?
Household (2-4 people, casual use): 15-lb daily consumption typical. Any of the four models is over-spec. Pick by ice type preference; production capacity doesn't matter.
Entertainers (weekend hosting, 8-12 guests): 30-45 lb daily during entertaining. OCR115 (90 lb/day) or ONP115 (85 lb/day) with 30-lb bin cycles empty-to-full in about 8 hours. Bin size is the constraint, not production rate.
Heavy entertainers (parties of 15+, weekly): 60-90 lb daily. Only OCR115 keeps up sustainably. If clear cube is essential, spec a second OCL115 or OCP115 to run in parallel — total 120 lb/day production with 60 lb bin.
Full-service bar zone: spec two ice makers side by side — one OCR115 for volume/rocks + one OCL115 for cocktails. Both fit standard 15-inch outdoor cabinet bays.
Filtration and water quality
U-Line recommends a sediment + carbon filter on every install:
- Sediment stage: removes rust, sand, and particles that clog the water solenoid
- Carbon stage: removes chlorine (makes ice taste better) and reduces mineral scale in the ice mold
- Filter housing: install between the water supply shutoff and the ice maker (~$60 for a good residential setup)
Skip the filter if your water is already softened + carbon-filtered at the whole-house level. Otherwise the $60 filter housing plus $30/year cartridge extends the ice maker's service life by years and dramatically improves ice taste.
Warranty and service
U-Line outdoor ice maker warranty: sealed system (compressor, evaporator, condenser) 3 years parts + labor, cabinet + components 1 year, ice mold + water valve 3 years, marine-grade hinges + fasteners 5 years. Warranty service through U-Line's national dealer network with parts shipped from their Wisconsin factory. Sealed-system claims average 3-4 week turnaround; water valve or mold replacements are 1-2 weeks.
Real-world spec by scenario
Default outdoor kitchen: OCR115 crescent. Highest production, most durable, lowest maintenance. $2,899. Covers 95% of use cases and never runs dry.
Design-forward or cocktail-focused bar: OCL115 (or OCP115 if no floor drain) clear cube. The presentation matters and 60 lb/day is plenty for a bar-scale operation. $3,299-3,599.
Kids in the household, iced-tea drinkers: ONP115 nugget. The ice they'll actually eat straight from the bin. $3,999.
Full-service entertaining: two units side by side — OCR115 for volume + OCL115 for cocktails. Combined ~$6,200, handles parties of 30+ without running out.
Retrofit or slab without floor drain: only the pump-drain models (OCP115 clear or ONP115 nugget) work. Don't spec a gravity model — the plumbing rework costs more than the pump upgrade.
