At \u003cstrong\u003e21 m³\u003c\/strong\u003e the Tallin 385 XL is the largest sauna we list, and the point at which a garden sauna becomes a building you spend an evening in rather than twenty minutes.\u003c\/p\u003e\n\n\u003cp\u003eThe proportions are what make it work. It is only 2.31 m wide, so it reads as a long, low pavilion rather than a shed. The terrace is under the same roof, so the cooling-off part of a session happens in shelter. And the changing room between the heat and the outside means the hot room stays hot every time somebody comes and goes.\u003c\/p\u003e\n\n\u003ch3\u003eSpruce or thermowood — your choice\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eNordic spruce\u003c\/strong\u003e is the traditional sauna timber: pale, clean-grained and bright inside. It is the more affordable build, and outdoors it needs treating and re-treating to stay looking new.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThermowood\u003c\/strong\u003e is timber kiln-treated at 180–220°C in a low-oxygen chamber. That is not a surface coating. It changes the wood itself, closing the cells so it absorbs far less moisture — which is what stops outdoor timber cupping, twisting and splitting through a British winter. No chemical preservatives are involved. It arrives a deep honey-brown and weathers to a stable silver.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOn a cabin this size the thermowood upgrade is worth serious thought.\u003c\/strong\u003e There is simply more timber exposed to the weather than on anything else in the range, so there is more to gain from it — and more to maintain if you do not.\u003c\/p\u003e\n\u003cp\u003eChoose your timber above.
