The Complete Buyer's Guide to Choosing an Outdoor Sauna
Size, timber, heater, glazing and installation. Everything worth deciding before you order.

Begin with capacity. A two to three person cabin suits couples and small gardens, four person models are the most popular by some distance, and six or eight person saunas suit families who entertain.
Then the timber. We build exclusively in Thermowood, so the decision is made for you, but if you are comparing elsewhere it is the single specification that most affects how a cabin ages outdoors.
Heating is the next choice: an electric heater is included and is the easier option, while a wood fired stove brings a softer heat and needs no electrical connection.
Glazing changes the character of the cabin more than anything else. A standard front is private and warm, half panoramic opens up the view while keeping privacy below, and a full panoramic front turns the sauna into a garden pavilion.
Finally, installation. Professional assembly is £990, self assembly is free, and bases and electrics can be quoted alongside so that one company handles the entire project.
