LionessHeart Posted January 9 Share Posted January 9 Hello - we want to install an electric outdoor sauna on a 3.5m x 3.5m level composite decking platform. The sauna will be 2m x 2m with a timber door and a single large (1500x1500mm) plate glass window. Please see attached hand-sketch and the finished look we'd like. Research on the net suggests a wide range of prices, but mostly £5K+. Our budget is closer to £3K. Would anyone know of an experienced local builder (near Langton Green/Tunbridge Wells/Kent) who might be able to build an outdoor sauna for us? We'll have equipped the sauna platform with single phase electricity and water source (for a cold, outdoor rustic shower). Any and all pointers will be most useful. Many thanks!

SteamyTea Posted January 9 Share Posted January 9 I used to make saunas, you are going to struggle at the price you are thinking of. Link to comment Share on other sites More sharing options...
LionessHeart Posted January 9 Author Share Posted January 9 Thanks for your prompt reply @SteamyTea. I should have mentioned the budget of £3K was without installation and the cost of utility connections.... What would be a reasonable budget for a 2x2m sauna? And, can you recommend an installer near TN3 (if we were to buy a modular/flat-packed one)? Link to comment Share on other sites More sharing options...
SteamyTea Posted January 9 Share Posted January 9 I can't recommend anyone these days. We used to make out own log saunas because of the high price of getting them imported. You can look at getting a log shed, and then modifying it. Probably your best bet. Link to comment Share on other sites More sharing options...

Any decent builder or diy'er could do it and it would be customised and probably sturdier. Link to comment Share on other sites More sharing options...
JamesP Posted January 9 Share Posted January 9 (edited) From my recent enquiries about building a sauna at home the internal material costs alone for a 2100 x 2100 are £2600.00 from here : https://www.saunashop.co.uk/product-range/details/2100-x-2100/377/ That price excludes all timber framing for walls , floor, roof, double glazing and any labour. I would expect a sauna in the above image to cost between 7.5 - 10K. Edited January 9 by JamesP Link to comment Share on other sites More sharing options...
SBMS Posted January 9 Share Posted January 9 What about one of these for 3900 https://www.fonteyn.co.uk/barrel-sauna-rustic-6-feet Link to comment Share on other sites More sharing options...
LionessHeart Posted January 9 Author Share Posted January 9 I understand the rounded ceiling of Barrel Saunas make them a less effective shape than a cube shape - @SteamyTea would you have an opinion on this given your experience? It also seems that the Polhus quote of £5.5K + installation for a 2x2m sauna might not be too much... Link to comment Share on other sites More sharing options...
LionessHeart Posted January 9 Author Share Posted January 9 thank you for this useful resource, @JamesP - I'll have a close look. Link to comment Share on other sites More sharing options...

A dome has less surface area than a cube. Link to comment Share on other sites More sharing options...

True, but I understand the shape of the barrel, because it doesn't allow for 2nd/high tier seating, reduces the efficient use of the hot air that accumulates near the ceiling. Seems like I need to read up on this! Thanks for your input. Link to comment Share on other sites More sharing options...
saveasteading Posted January 10 Share Posted January 10 I suggest first establish what geometry is best. There is no point in having an unpleasant space. Then we look at the best way to build it. Lots of insulation for sure, and draught free. Link to comment Share on other sites More sharing options...
SteamyTea Posted January 10 Share Posted January 10 16 minutes ago, saveasteading said: and draught free No. Saunas, because of the high temperatures , and associated convection, need proper ventilation. People worry about the off-gassing of foam insulation that is behind a VCL, but don't give too hoots for the VOCs coming off timber. Link to comment Share on other sites More sharing options...
saveasteading Posted January 10 Share Posted January 10 No. You know better than that. Controlled ventilation requires an absence of draughts. Airtight first, ventilation second. Unless the occupants are wearing warm clothing. Link to comment Share on other sites More sharing options...
SteamyTea Posted January 10 Share Posted January 10 3 hours ago, saveasteading said: You know better than that I do, but with a sauna, which is a relatively flimsy timber structure, that is thermally cycled, with ΔT of 80K, uncontrolled ventilation becomes a fact or life, so embrace it. Just make sure that there is a controllable vent on the roof. Link to comment Share on other sites More sharing options...
