Sauna Building & Installation
The Sauna Company is London's most experienced bespoke sauna installer, with over 15 years and 100+ custom sauna installations completed across London and the surrounding counties of Surrey, Hertfordshire, Berkshire, Essex and Kent. Whether you are searching for a sauna installer near you in Notting Hill, a custom sauna builder in Surrey, or simply want to understand what a professional sauna installation involves, you've come to the right place. Every sauna we build is designed and constructed on-site, fitted precisely to your available space — not the other way around. We are not a catalogue company. We are sauna builders who treat every project as a bespoke commission, from the first design consultation to the moment you step inside for the first time.
As a full-service sauna installation company, we handle every stage of your project in-house — sauna design, ventilation engineering, timber selection, heater specification, electrical coordination and the build itself. Our sauna installation service covers the full range: indoor Finnish saunas, infrared saunas, hybrid saunas, outdoor garden saunas, Himalayan salt saunas, steam rooms and luxury climate-controlled wellness spaces. No space is too awkward. We have installed custom saunas in converted WCs, under stairs, inside garage conversions, garden sheds, loft rooms and pool houses across London and the Home Counties. If you have been told by another builder that a sauna "can't be done" in your space, call us — that is precisely the kind of challenge we specialise in.
What separates a great sauna installation from a costly disappointment is ventilation — and it is where most installers cut corners. At The Sauna Company, before we discuss timber finishes or heater brands, we calculate air volumes, model heat distribution and design a ventilation system engineered to your specific room dimensions. We use only Scandinavian-grade sauna timbers — Aspen, Alder, Thermo Aspen and Thermo Alder — and source our heaters exclusively from Finland's most trusted manufacturers: HUUM, Harvia and Saunum. We are proud members of the British Sauna Society, and every custom sauna installation we complete is backed by our aftercare service. When you search for a sauna installation near you in London, you want a sauna builder with a proven track record — not a general contractor with a brochure.
We install bespoke saunas throughout Greater London and the surrounding counties, covering areas including Kensington, Chelsea, Hampstead, Islington, Clapham, Notting Hill, Richmond, Wimbledon, Kingston, Bromley, Surrey (including Weybridge, Virginia Water, Oxshott, Guildford and Esher), as well as Hertfordshire, Berkshire and Essex. Our process begins with a free design consultation — we visit your space, take measurements, discuss your vision and produce a full 3D visualisation before a single board is laid. Whether you are a homeowner, an architect or an interior designer, we are the custom sauna builders London trusts for installations that perform as beautifully as they look. Get in touch today to book your free sauna installation consultation and take the first step towards your bespoke sauna.
