Hot Bain Marie

Q: Can a bain marie cook food, or only hold it?

Bain maries are holding equipment — they keep already-cooked food at safe service temperature (above 60°C). They are not designed to cook raw or refrigerated food up to temperature; that's what a combi oven or stove does.

Commercial bain marie food warmers for restaurants, cafés, pubs, buffets and catering — keep cooked food at safe service temperature without drying it out. Our range covers wet bain marie, dry bain marie and combination wet-and-dry units in countertop, bench and floor formats from Thermaster, Bonvue, FED and other commercial brands. Browse all commercial cooking equipment or jump straight to chip warmers for fried-food holding.

Wet bain marie or dry bain marie? Wet units (water-bath) hold delicate items like sauces, pasta, vegetables and soups without drying — best for items already in their own moisture. Dry units use direct heat for items that hold heat naturally (rice, fried items, baked dishes). Most operators end up with a wet-and-dry combination unit so the same setup covers both. For a deeper comparison, read our wet vs dry bain maries guide.

Popular picks in this range include the Thermaster Wet & Dry Bain Marie Display – 5×1/1 GN Pans (PG180FEXG) for buffet and cafeteria service, and the Bonvue Square Countertop Wet & Dry Bain Marie (BM17SC) when bench space is tight.

Frequently asked questions

What is a bain marie?

A bain marie (also spelled "baymarie", "bane marie" or "bay maree" — they all refer to the same thing) is a commercial food warmer that holds cooked food at safe service temperature for extended periods. The name comes from the French bain-marie meaning "Mary's bath" — a water-bath cooking and holding method.

What's the difference between a wet bain marie and a dry bain marie?

A wet bain marie holds water (or steam) in a heated chamber and uses that moisture to keep food warm without drying it out. A dry bain marie uses dry heat. Wet units suit sauces, soups, pasta and vegetables; dry units suit fried items, rice and baked dishes. Combination wet-and-dry units cover both.

What size bain marie do I need?

Sizing is usually expressed in 1/1 GN (Gastronorm) pan slots — a 4×1/1 unit holds four full-size GN pans, a 5×1/1 holds five, and so on. For a 50–100 cover restaurant, a 4–5 GN bench unit is typical; high-volume buffets and catering operations run 6–8 GN floor units or multiple bench units in line.

Electric or gas bain marie?

Most commercial bain maries in Australia are electric — they're easier to install (standard 10A or 15A power), don't need a gas connection, and are safer for indoor service areas. Gas bain maries are usually back-of-house only and need a licensed gasfitter for installation.

Do bain maries need a Gastronorm pan to work?

Yes — bain maries are designed to hold standard 1/1, 1/2, 1/3 etc. GN pans. Pans are sold separately. Some commercial bain marie sets come with pans included; check the product spec table.

Can a bain marie cook food, or only hold it?

Bain maries are holding equipment — they keep already-cooked food at safe service temperature (above 60°C). They are not designed to cook raw or refrigerated food up to temperature; that's what a combi oven or stove does.

What's the warranty on commercial bain maries?
