Choosing the right sauna size

Sauna capacity is generally stated as a maximum seating guide, not a maximum comfort guide. Use the points below to specify what will work best for your needs.

Practical sizing rules

Factor Allowance
Seated adult bench space Around 600mm width per person
More comfortable seating 700mm+ width per person
Bucket and ladle space Allow 200–300mm width
Lying down Around 1800–2000mm bench length
Heater, door and access space Don’t count this as usable seating space
L-shaped or opposing benches Better for families, guests and more social use
Commercial use Size for comfort, flow and turnover, not just headcount

Typical sizing scenarios

Use case What to allow for
Single regular user A compact sauna can work well, but choose enough bench length if you want to stretch out.
Couple A 2 person sauna may be enough, but a 3 person layout usually feels more comfortable.
Family use Prioritise movement, access and a layout that lets people sit without crowding the door or heater.
Occasional guests Size around normal use first. A 4 person sauna may feel better for 2–3 regular users.
Social use Consider L-shaped or opposing benches so users can face each other rather than sit in a single row.
Relaxed home sauna Allow more width per person, space for towels, accessories and easier movement.
Commercial sauna Consider peak demand, session turnover, safe movement, cleaning access and customer comfort.

Not sure what size is right for you? Send us your room dimensions and intended use, and we’ll help you narrow it down.

Calculate the heater kW needed for your sauna

Enter the details of your sauna size below to output the recommended sauna heater kW. Cold areas such as full glass front or door should be added for a better match.

Sauna room size
Construction
Your effective sauna volume is:
Recommended sauna heater kW:
Browse heaters

Rule of thumb: Allow around 1kW per 1m³ of effective sauna volume. Extra glass, tile, stone, and log construction can push the requirement higher.

Getting your new sauna up and running

Harvia and Tylö sauna kits are well made and typically straightforward to assemble, with clear, model-specific instructions. If you’re comfortable with flat-pack furniture, you’ll be fine.

Pre-installation: Plan the location, and a solid, level base. For traditional saunas, book a qualified electrician for the heater connection.

  • Home: Check your clearances and ventilation, and have a level base ready. If you’re genuinely stuck, call us for expert advice.
  • Commercial: Same basics as home. Have your electrician verify the building supply early. Some larger heaters may need 3-phase power. Speak to us about your installation if you need advice.
  • Infrared: Cabins with a UK 3-pin plug are plug-and-play into a standard wall socket. Avoid extension leads. Hybrid models with separate sauna heater will need a qualified electrician for the connection.
