Bespoke Sauna Installation in Kensington & Chelsea
We design and build bespoke saunas for homes across Kensington & Chelsea, from Holland Park and Notting Hill to Chelsea and South Kensington. Every sauna is measured and built on site to fit the space you have, and fully installed prices start from £9,995, depending on size and design.
Many homes in the borough are already fully extended, so the sauna usually has to fit somewhere unexpected: a spare WC, a garden shed, a basement room or a corner of a bathroom. That is the kind of brief we work on most.
Saunas we’ve built in Kensington & Chelsea
Garden shed sauna, Holland Park
The townhouse had no spare room left, so the sauna went into an existing garden shed that had been used for storage. We kept the shed roof, reclad the outside in pre-painted black cladding and fitted a new door and window. Inside, the sauna is lined in horizontal Thermo Aspen, with a glass front and door opening onto a cold water shower. A HUUM CLIFF heater with Wi-Fi control and colour-changing ambient lighting complete it.
Spare WC converted to a sauna, Notting Hill
A disused spare WC became a two-person sauna. The room is lined in horizontal Thermo Aspen to make the narrow space feel wider, with a ventilation layout designed for the small volume and warm, low-level lighting. A wall-mounted Harvia heater with built-in controls saves floor space and needs no separate control panel.
What to plan for in a Kensington & Chelsea home
-
Listed buildings and conservation areas. Much of the borough is in conservation areas, and some houses are listed. Internal work in a listed building may need listed building consent, and a new garden structure may need planning permission. We will tell you early whether your design is likely to need either, so you can check with the council before work starts.
-
Flats and mansion blocks. If you own a leasehold flat, you will usually need the freeholder’s consent for building work. We can provide drawings and specifications to support that request.
-
Access. Every sauna is built on site from timber brought in by hand, so narrow stairs and lifts are not a problem in the way they are for prefabricated cabins.
-
Power. The two saunas above run on single-phase heaters. We size the heater to the room and tell you what the electrical supply needs before you commit.

We build traditional Finnish, infrared, hybrid, Himalayan salt and outdoor saunas, as well as steam rooms.

Frequently asked questions
How much does a sauna cost in Kensington & Chelsea?
Our bespoke saunas start from £9,995 fully installed. The final price depends on size, sauna type, timber and how much building work the space needs. Prices are the same across London and Surrey.
Can you fit a sauna in a small room or a WC?
Yes. Our Notting Hill project turned a spare WC into a two-person sauna. Compact wall-mounted heaters and floating benches make small rooms workable.
Do I need planning permission for a sauna in a conservation area?
An indoor sauna in a house that is not listed does not usually need planning permission. Listed buildings and new garden structures may need consent. We will flag this at design stage, and you should confirm with the council.
Can a garden shed be turned into a sauna?
Often, yes. In Holland Park we built a sauna inside an existing storage shed, keeping the roof and recladding the outside. We check the structure, insulation and power supply first.
How long does installation take?
A traditional or infrared sauna typically takes 3–5 days on site. Hybrid and Himalayan salt saunas take 2–3 weeks. We confirm timings in your quotation.
