Rigg Saunas

Bespoke sauna design & build — London & UK

Saunas, designed as architecture.

A London studio designing and building custom saunas from first principles — proportioned to site, material and use. No kits, no catalogue.

Much of the sauna market is built on repetition.

We treat each commission as a design and fabrication problem — proportion, material behaviour, thermal performance and context resolved as one. Architecture and design first; saunas reconsidered without compromise.

Three ways to commission

01 ArchitecturalPermanent saunas integrated into buildings — resolved with the structure, not added to it. → 02 GardenFreestanding structures for outdoor settings, sited for orientation, groundworks and landscape. → 03 MobileEngineered for movement — proportion and thermal performance held, resolved as a complete structure. →

Material

Detailed for heat, moisture and a life of use.

Material selection and detailing are developed alongside the design, not after it — informed by heat retention, ventilation and the realities of regular use.

We build for longevity and performance over short-term visual impact. Every joint, bench and line is considered.

The studio position

No kits. No catalogue. Every project an original.

A design-and-fabrication studio — every sauna drawn and made in our own East London workshop, so material, detail and thermal performance answer as one.
