Garden saunas

Every garden sauna we build is bespoke. It’s designed and built entirely around you, your garden and how you’ll use it, rather than around what a pre-made kit can offer. The size, the shape, the glazing, the bench layout and how it sits in the garden all start with a conversation, not a catalogue.

It’s built using the same timber-frame methods as a new home, made for use all year round. That matters more for a sauna than almost any other garden room, because the building has to deal with real heat and moisture every time it’s used.

Two founders on every project. Josh and George, our two founders, are on every project, with twenty-plus years of combined experience in the trade between them. We work alongside trusted specialists where a job needs them.

Heat and electrics done properly. Electrics come as standard. For an electric sauna, our dedicated electrical team installs the heater supply and the rest of the electrics, signed off and connected to your house’s main board. For a wood-fired sauna, we design in the flue and clearances, with lighting and other electrics signed off the same way.

The right base for your garden. We build on a concrete slab or ground screws, chosen for the building, the ground and what goes inside it.

Plenty of people want more than the hot room alone. We can plan the whole space with you.

Cold plunge. We can supply and fit cold plunges. A plunge typically weighs well over 500kg when full, so we plan the base, the drainage and the power for it from the start — a concrete slab, or ground screws with decking above — along with a sensible spot to step out of the sauna and straight in.

Changing area, shower and WC. These are available on request. A shower typically needs an extract fan to clear the steam. Please bear in mind that a toilet or shower may mean the building needs planning permission, because of how the guidance treats bathrooms, so it’s worth checking with your council early. Water, waste and drainage connections also need to meet the Building Regulations.

Somewhere to sit afterwards. A bench, a small lounge or a covered spot outside the door can make a real difference to how the space feels. We’ll talk through what suits you and your garden.

Planning permission. Most garden rooms, including garden saunas, can be built as permitted development, as long as they meet every limit. The key ones are that the eaves can be no higher than 2.5 metres, and if any part is within 2 metres of a boundary, the whole building must be no higher than 2.5 metres. We design to the 2.5 metre limit as standard. A sauna for you and your household would normally count as incidental use of your home.

If permission is needed, we help. We help clients apply for planning permission or a Lawful Development Certificate, and we can arrange architects or planning consultants where needed.

Building regulations. These are a separate question. According to the Planning Portal, building regulations will not normally apply to a garden building under 15 square metres with no sleeping accommodation. Between 15 and 30 square metres, approval isn’t normally needed if the building is at least 1 metre from any boundary or built substantially of non-combustible materials. We handle building control sign-off on larger rooms.

Electrics. Even when the building itself is exempt, sauna electrics are notifiable under Part P and follow the wiring regulations for saunas (BS 7671 Section 703). Our dedicated electrical team signs the work off and connects it to your house’s main board.
