What Is an 18" Undercounter Ice Maker?
An 18-inch undercounter ice maker is a commercial-grade ice machine that is approximately 18" wide and designed to fit beneath counters, bar tops, or service stations. Because of its space-saving size, it’s ideal for situations where a full-size ice machine won’t fit but you still need reliable ice production.
These units are commonly found in:
-
Restaurants and cafés
-
Bars and lounges
-
Hotel ice stations
-
Office break rooms
-
Small kitchens or prep areas
-
Home bars (commercial-quality)
Why Choose an 18" Undercounter Ice Maker?
✔ Space Efficiency
With an 18" width, it fits under most counters, maximizing kitchen or bar space.
✔ Quick Ice Access
Perfect for service stations where staff need ice within arm’s reach.
✔ Professional Output
Delivers consistent ice — typically more than portable or residential units.
✔ Flexible Placement
Can be installed under bars, counters, islands, or in small utility areas.
Typical Ice Production & Capacity
| Feature | Typical Range |
|---|---|
| Daily Ice Production | ~50–150 lbs/day (varies by model) |
| Storage Capacity | ~15–40 lbs |
| Ice Type | Cube, half-cube, or chewable (depends on model) |
???? Production numbers vary by brand, system design, and ambient temperature — always check the manufacturer’s specs.
Common Ice Types You May Get
-
Cube Ice – Great for drinks (slow-melting)
-
Half-Cube – Smaller, faster freezing
-
Chewable Ice – Softer ice for beverages with quick cooling
Key Features to Look For
1. Stainless Steel Construction
Strong, easy to clean, and suitable for commercial environments.
2. Efficient Compressor
Ensures dependable ice production even in busy service hours.
3. Water Filtration Compatibility
Improves ice taste and reduces scale buildup.
4. Auto Shut-Off
Stops production once the bin is full — saves energy and prevents overflow.
5. Easy Access Lid
Top-opening design makes scooping ice easy for staff or guests.
Installation Requirements
✔ Under-counter space with ~18" width clearance
✔ Water supply line with proper pressure
✔ Drain line for condensate
✔ Dedicated electrical outlet
✔ Ventilation space around the unit (check manufacturer recommendations)
Proper installation ensures optimal performance and longer life.
Maintenance Tips
???? Clean interior and ice bin regularly — every 3–6 months is ideal.
???? Replace water filters as recommended.
???? Check vents & condenser for dust buildup.
???? Sanitize water lines periodically.
???? Inspect seals & gaskets for wear or damage.
Regular care keeps ice quality high and prevents breakdowns.
Common Undercounter Ice Maker Issues & Fixes
Low Ice Output → Check water supply, filters, and condenser airflow.
Ice Clumping → Ensure proper temperature and clean ice bin.
Bad Taste → Replace filters and clean internal surfaces.
Noise or Vibration → Check installation level and airflow clearance.
Who Is It Best For?
An 18" undercounter ice maker is ideal if you:
✔ Need ice production near the point of service
