Cold room vs. refrigerator
for the commercial kitchen
From what volume is a walk-in cold room more economical than individual professional refrigerators? Concrete cost comparison, energy analysis and tipping point by venue type.

Tipping point
Under 80 covers per day: professional refrigerators (Hoshizaki Premier or Snowflake). From 80–100 covers: walk-in cold room. In practice often the combination: cold room for stock plus refrigerated counters for daily operation.
When to choose individual refrigerators
For small and mid-sized kitchens (up to 80 covers per day), 2–4 professional refrigerators are generally cheaper, more flexible and better integrated into the work area. Hoshizaki Premier or Snowflake is the standard.
Advantages of individual refrigerators: lower purchase cost for small volumes, no refurbishment needed, directly integrated into workflow (no walking), simpler HACCP zoning (meat, fish, vegetables, dessert separate). Also: if one unit fails, the others keep running.
When to choose a walk-in cold room
From 80 covers per day or with higher stock requirements (catering company, hotel, production kitchen) a walk-in cold room wins on cost per litre, energy efficiency and organisation of bulk deliveries.
Advantages of the cold room: lower cost per litre of capacity, 30–45 per cent more efficient per litre, better organisation of bulk deliveries (crates can be rolled straight in), less floor space for the total volume. Also: easier to extend with modular systems.
Cost comparison: 10,000 litres capacity
For a total cooling capacity of 10,000 litres (approx. 80–100 covers per day) the following cost comparison over 10 years. Including purchase, energy and maintenance. The cold room becomes cheaper after 5–7 years.
| Cost item | 5 refrigerators | 10 m³ cold room |
|---|---|---|
| Purchase | €12,500 | €11,000 |
| Electricity/year | €1,800 | €1,100 |
| Maintenance/year | €450 | €350 |
| Total 10 years | €34,000 | €25,500 |
| Floor space | 6 m² | 10 m² (separate) |
Calculation 2026, average electricity price €0.30 per kWh. Actual savings vary by situation.
The best solution: often a combination
In practice, mid-sized and large kitchens frequently work with a combination: 1 walk-in cold room for stock and bulk deliveries, plus 1–3 refrigerated counters for operational use near the cooking zone. This gives the best of both worlds.
Example for a restaurant with 120 covers: 1 walk-in cold room of 8 m³ (stock + bulk purchasing) plus 2 Hoshizaki refrigerated counters (operational use). Plus a separate freezer room for frozen products. Investment approx. €18,000–25,000.
Frequently asked questions
From what point is a cold room more economical than refrigerators?
The tipping point is around 80–100 covers per day or more than 1,500 litres of required cooling capacity. Below this volume, 2–3 professional refrigerators (Hoshizaki Premier or Snowflake) are cheaper. Above this volume a walk-in cold room wins on kWh per litre and storage efficiency.
What is cheaper to buy: a cold room or a refrigerator?
Per litre of storage volume a walk-in cold room is cheaper. A 10 m³ cold room (approx. €8,000–15,000) provides 10,000 litres of capacity. For the same 10,000 litres you would buy 5–6 Hoshizaki Premier refrigerators (each 1,400 litres, approx. €12,000–18,000 combined). A cold room also saves floor space.
Does a cold room use more or less energy than refrigerators?
Per litre of cooling capacity a well-insulated walk-in cold room uses 30–45 per cent less energy than individual refrigerators. Better insulation ratio and a larger compressor running more efficiently. Without good door discipline this advantage can be lost to cold loss on every pass.
Can a cold room be extended later?
Modular cold rooms can be extended by adding panels. Plan the dimensions and unit capacity in advance. A built-in cold room is much harder to adapt. We recommend modular solutions for growing operations.
Which combination works best in practice?
For mid-sized restaurants and catering: 1 walk-in cold room (stock, 6–12 m³) plus 1–2 refrigerated counters (operational daily use). For care facilities: 1 large cold room for meal regeneration plus a separate freezer room for frozen products.
How involved is the installation of a walk-in cold room?
A walk-in cold room requires: load-bearing floor (with vapour barrier for freezer room), 3-phase power supply, ventilation around the unit, sloped floor for drainage. Installation time 1–2 days. With JMGT this is standard included in the quote.
