Commercial Saunas: Infrared & Barrel Buyer's Guide (2026)

A commercial sauna in 2026 typically costs £6,000 to £25,000 depending on type, size and finish. Infrared cabins run cooler (around 45°C – 60°C) and install easily on standard power; traditional and barrel saunas reach 70°C – 90°C for a classic, high-heat experience. The right choice depends on your space, power supply and the experience your members expect.

What types of commercial sauna are there?

Operators generally choose between three formats. Each suits a different space, budget and member expectation. Explore the full range in our heat therapy collection.

• Infrared cabins heat the body directly with radiant panels, operating at lower air temperatures and installing on standard power.
• Barrel saunas deliver a traditional high-heat experience in a striking cylindrical form, ideal as an outdoor or destination feature.
• Traditional indoor cabins use a heater and stones for the classic Löyly steam experience at the highest temperatures.

How much does a commercial sauna cost?

Pricing turns on type, capacity, materials and whether the unit sits indoors or out. The figures below are indicative, typical ranges for planning only; final pricing depends on specification and site.

The striking Eldur barrel sauna sits in the destination category – a high-heat, visually arresting feature that doubles as a marketing asset for spas, hotels and recovery studios.

Infrared or barrel: which should you choose?

Infrared cabins are the pragmatic choice where power and space are limited. They warm quickly, run on standard supply and suit indoor wellness floors. Barrel and traditional saunas deliver the authentic, high-heat ritual many members seek – the steam, the heat, the social bench – and make compelling outdoor or feature installations.

Which works best outdoors?

Barrel saunas excel outdoors. Their shape sheds rain, heats efficiently and creates an eye-catching garden or courtyard feature for hotels and spas. Infrared cabins are generally best kept indoors.

Which heats up fastest?

Infrared cabins reach operating warmth quickly because they heat the body rather than a large air volume. Traditional and barrel saunas take longer to reach their higher temperatures but reward the wait with that classic enveloping heat.

What should operators check before buying?

Before committing, confirm power supply (some traditional heaters need three-phase), ventilation, drainage for any wet area, floor loading and access for delivery and assembly. Factor in member throughput too: heat sessions are longer than cold, so capacity planning matters for busy sites. Sauna heat is associated with relaxation and post-exercise comfort, and individual results vary; keep messaging at the modality level, as this is wellness equipment rather than a medical device.

Capacity ranges from two or three in a compact infrared cabin to six or eight in a larger traditional cabin. Match capacity to expected peak demand.
