Every Detail
Considered
Bespoke Architectural Design
Every outdoor sauna is designed from scratch around your garden, property style, and brief. We produce full CAD drawings and 3D visualisations before a single piece of timber is cut.
Weather-Resistant Materials
We specify only timbers proven in the British climate — Western Red Cedar, Thermowood, and Larch — each chosen for their natural resistance to moisture, movement, and UV exposure.
Planning Guidance Included
Most garden saunas fall within permitted development rights. We advise on planning requirements as part of every consultation and can liaise with local authorities on your behalf.
Full Electrical & Plumbing Integration
We manage all services — power supply, lighting circuits, drainage, and water supply — coordinating with your existing contractors or providing our own trusted network.
Insulated for Year-Round Use
Our outdoor sauna structures are fully insulated to perform in all British weather conditions — reaching temperature quickly and holding heat efficiently, even in winter.
Heater Selection & Installation
We work with Harvia, Huum, and Narvi — the leading Finnish heater manufacturers. We recommend the optimal model for your sauna size, usage pattern, and aesthetic.
The Poolside
A standalone outdoor sauna pavilion integrated into a landscaped garden, featuring panoramic glazing and Western Red Cedar cladding.
The Retreat
A contemporary garden sauna building with floor-to-ceiling glass, a larch wraparound deck, and a wood-burning Harvia heater.
Garden Sauna FAQs
Do I need planning permission for a garden sauna in the UK?
In most cases, no. Garden saunas typically fall within permitted development rights, meaning no formal planning permission is required. However, this depends on your property type, size, and location — particularly if you are in a conservation area or listed building. We provide guidance on this as part of every consultation.
What is the best timber for an outdoor sauna in the UK?
Western Red Cedar is our most popular choice for outdoor saunas — it is naturally aromatic, highly resistant to moisture and decay, and weathers beautifully in the British climate. Thermowood and Larch are excellent alternatives, offering a darker aesthetic and outstanding durability.
How long does a garden sauna installation take?
Most standalone garden sauna installations take between 5 and 10 days on site, depending on the size and complexity of the structure. We provide a precise timeline at the quotation stage.
Can a garden sauna be installed near a pool?
Yes — poolside saunas are one of our most popular projects. We design the structure to complement the pool area, with appropriate drainage, non-slip decking, and glazing to frame the view.
