Where to Put a Home Sauna: Every Realistic Spot in a UK Home

Updated July 2026. "Where would it even go?" stops more sauna purchases than price does. The honest answer: more places than you think. Here's every realistic location in a UK home, with the practical requirements and the pitfalls for each.

What Any Location Needs

Four things: a hard, level floor (tile, concrete, laminate, solid wood — carpet is workable but a hard base board is better); ceiling height of around 1.9–2.1m depending on the cabin; a power supply (standard 13A socket for most 1–2 person cabins — see our electrics guide); and a small air gap of 5–10cm around the cabin. Infrared cabins need no plumbing, no flue, and no dedicated ventilation — which is what opens up so many locations.

Spare Bedroom or Box Room

The most popular choice. A compact 1-person cabin at 900mm square takes less floor than a wardrobe, and a 2-person cabin fits comfortably in a standard double room. Check the ceiling height upstairs in older properties and measure the stair access — cabins arrive as flat panels, so tight turns are rarely a problem, but check the longest panel dimension against your stairwell.

Home Gym or Garage

The natural pairing — post-workout infrared sessions are the main reason many buyers purchase. Garages work well provided the space is dry; a damp, unheated garage will age the timber and electronics. If your garage has a single spurred socket, have an electrician confirm it's happy with a continuous 2 kW load. Insulated garage conversions are ideal.

Bathroom or En-suite

Fine for infrared — the cabin itself is dry heat — but placement matters: outside splash zones, on a ventilated wall, in a bathroom big enough to keep the air gap. Compact 900mm cabins occupy the same footprint as a shower enclosure, which is exactly how many owners use them.

Basement or Cellar

Excellent if dry — stable temperature, out of the way, and the concrete floor is ideal. Test humidity first; a dehumidified, tanked basement is perfect, an untreated damp cellar is not.

Garden Room or Conservatory

A garden office or insulated garden room takes an indoor cabin happily and makes a genuine wellness annex — run the electrics properly (an armoured outdoor supply to the building, installed by an electrician). Conservatories work but summer heat and winter cold swings are hard on timber; an insulated garden room is the better version of this idea. For a cabin that lives fully outside, choose a weather-rated outdoor infrared sauna instead — indoor cabins are not weatherproof.

Landing, Alcove or Under the Stairs?

Occasionally — the constraint is ceiling height and the air gap. Measure honestly. A cabin crammed into an alcove with no clearance runs hotter around the electronics than it should.

Where Not to Put One

Uninsulated outbuildings and damp sheds (moisture kills timber and electronics), directly on thick carpet without a base board, anywhere the cabin blocks a fire escape route, and outdoors — unless it's a purpose-built outdoor model.

Sizing It

Measure floor space, ceiling, and access route, then match to capacity: 1 person from 900mm square, 2 person from around 1m, 3 person around 1.5m, 4 person around 1.8–2m. Exact dimensions are on every product page, and our team will sanity-check your space over the phone: 0330 133 6617.

FAQs

Where is the best place to put a sauna in a house?

A spare bedroom, home gym or dry garage are the most popular locations — hard level floor, 1.9–2.1m ceiling, a standard socket, and a small air gap are all most cabins need.

Can you put an infrared sauna in a bedroom?

Yes — compact cabins take less floor space than a wardrobe, run on a standard socket, and produce dry heat with no steam or humidity issues.

Can you put an infrared sauna in a garage?

Yes, provided the garage is dry. Damp, unheated garages age the timber and electronics — insulated or converted garages are ideal.

Can an indoor sauna go outside?

No — indoor cabins are not weatherproof. For garden installation choose a purpose-built outdoor infrared sauna with weather-rated construction.

Do infrared saunas need ventilation?

No dedicated ventilation — just a 5–10cm air gap around the cabin and normal room airflow. There's no steam, flue or plumbing involved.
