Measure the space before you look at models
Undercounters must fit an existing counter run or create one. Measure the height to the underside of the counter, the depth available, and the width between legs, walls or other units. Standard counter heights are usually 850 to 900 mm, and common cabinet depths are around 600 mm or 700 mm; deeper units take full-size gastronorm pans front to back. Note where the socket is and whether there is room for air to move behind or in front of the unit.
Doors or drawers
Drawers suit hot lines where cooks open a unit dozens of times an hour. Doors suit bars, cafés and prep areas where items are taller and openings are fewer. Many kitchens mix both in one counter run.
| Doors | Drawers | |
|---|---|---|
| Access | Need to bend and reach to the back | Pull out; everything visible from above |
| Cold air loss | Whole section loses air when opened | Only the open drawer loses air |
| Storage shape | Shelves; good for tall bottles and tubs | GN pans; good for portioned mise en place |
| Aisle needed | Door swing | Drawer extension plus the person standing |
| Cost | Lower | Higher; runners and slides add cost |
Front-breathing versus rear-breathing
Every refrigerator has to get rid of heat. Rear-breathing units push it out of the back and need open space behind them. Front-breathing units draw in and exhaust air through a grille at the front, so they can be built into a counter with little or no gap. If the undercounter will be enclosed by other cabinets or a wall, ask specifically whether it is front-breathing; an enclosed rear-breathing unit recirculates its own hot air and loses capacity quickly.
Living next to the fryer
- Keep the condenser grille away from fryer, oven and dishwasher exhaust.
- Ask for the rated ambient temperature, and expect a hot line to exceed 40 °C at knee height.
- Plan to clean the condenser every two to four weeks; grease and flour clog it fast.
- Prefer drawers or half-height doors where staff open the unit constantly.
Using the top as a work surface
Some undercounters are designed to slide beneath your own counter; others come with their own worktop and can stand alone. If staff will chop, roll or plate on the top, ask for stainless steel of a suitable grade (304 resists salt and acids better than lower-nickel grades), a raised rear upstand to stop spills running behind the unit, and a top strong enough for the equipment you plan to put on it. Never put a hot griddle or grill on an ordinary undercounter; that needs a chef base built for the heat.
Hygiene and cleaning
FSSAI hygiene expectations include keeping equipment and the floor beneath it clean. Choose legs high enough to clean under, or castors with brakes so the unit can be rolled out. Inside, rounded corners, removable shelves or drawer liners and push-in gaskets that pull out for washing make the weekly clean faster and more thorough. Drawer units collect crumbs and spills in their runners, so check that the drawer frames lift out without tools. Outside, a smooth stainless front without deep seams wipes down quickly between services and does not hide residue.
How many sections?
Undercounters are usually sold as two, three or four sections wide. Count the GN pans or containers each station needs for one service plus a buffer, then pick the narrowest unit that holds them with room for airflow. A longer unit is not automatically better: it may push the cook's other equipment out of reach, and more doors mean more gaskets to maintain.
Questions to ask before you order
- What are the exact external dimensions, including handles, and the depth with a door or drawer fully open?
- Is it front-breathing, and what clearance does it need on each side?
- Which GN pan sizes and depths fit each drawer or shelf, and how many?
- What room temperature is it rated to hold +2 to +8 °C at, and how quickly does it recover after opening?
- What voltage range does it run on, and does the controller delay restart after a power cut?
- Are drawer runners, gaskets and fans stocked locally as spares?
Frequently asked questions
- Can I get an undercounter freezer?
- Yes, undercounter freezers exist, but they work harder than refrigerators in a hot line. Use them for small quantities of frozen items needed at the station and keep bulk frozen stock elsewhere.
- What temperature should an undercounter hold?
- Most are designed for +2 to +8 °C. For food-safety purposes, many kitchens aim to keep chilled food at 5 °C or below and log it at opening and closing.
