Commercial Saunas: Traditional, Barrel & Infrared Buyer's Guide (2026)
Buying a commercial sauna in 2026? Compare infrared vs barrel saunas on cost, capacity, heat and install, with indicative GBP pricing for operators.
A commercial sauna in 2026 typically costs £6,000 to £25,000 depending on type, size and finish. Traditional and barrel saunas reach 70°C – 90°C for the classic, high-heat experience; infrared cabins run cooler (around 45°C – 60°C) and install easily on standard power. Helix supplies traditional and barrel saunas — we cover infrared here for comparison, but it is not a format we stock. 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. The two Helix supplies — traditional cabins and barrel saunas — are shown in our heat therapy collection.
- Traditional indoor cabins use a heater and stones for the classic Löyly steam experience at the highest temperatures — the deepest evidence base and the ritual most guests recognise.
- Barrel saunas deliver that same traditional high-heat experience in a striking cylindrical form, ideal as an outdoor or destination feature.
- Infrared cabins heat the body directly with radiant panels at lower air temperatures and install on standard power. Efficient and gentle, though not a format Helix stocks.
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.
| Type | Indicative cost (GBP) | Typical temperature | Capacity |
|---|---|---|---|
| Traditional cabin (6–8 person) | £12,000 – £25,000 | 70°C – 90°C | 6 – 8 |
| Barrel sauna (4–6 person) | £8,000 – £18,000 | 70°C – 90°C | 4 – 6 |
| Infrared cabin (2–3 person) | £6,000 – £12,000 | 45°C – 60°C | 2 – 3 |
| Running cost (energy) | Varies by use | – | – |
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.
Traditional, barrel or infrared: which should you choose?
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. This is where Helix focuses, and where the strongest long-term evidence sits. Infrared cabins are the pragmatic alternative where power and space are limited: they warm quickly and run on standard supply, but you would source them elsewhere.
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.
FAQ
Does Helix sell infrared saunas?
No. Helix supplies traditional and barrel saunas. We include infrared in this guide for a fair comparison, but it is not part of our range.
Is infrared or traditional sauna better?
Neither is universally better. Traditional and barrel saunas deliver the authentic high-heat ritual and the deepest evidence base; infrared offers gentler heat and easy install. Choose by your space, power and the experience your members want.
How many people does a commercial sauna hold?
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.
What power supply do I need?
Larger traditional heaters may require three-phase, while many compact cabins run on standard single-phase power. Confirm with your electrician before ordering.
How long does installation take?
Barrel and modular cabins often assemble in a day or two; built-in traditional rooms take longer. Lead times vary with specification, so order early.
