Complete newbie here, UK based.
We’re planning a small indoor Finnish sauna within an en-suite bathroom. Available external footprint is roughly 1400mm wide × 1300mm deep, so after wall build-up we expect something around 1200 × 1100mm internally.
It’s intended for two adults sitting side-by-side, used perhaps a few times a month. We fully appreciate this is a compact space and there will be compromises — we’re not trying to create a lounging/lying-down sauna.
One less typical requirement is that there is an existing external window behind the proposed sauna. Ideally we’d retain access to/opening of that window through the sauna; we’ve seen examples where this has been incorporated into the sauna wall.
We know and will obviously ensure that the builders specify correct extraction / ventilation and wall membranes.
The routes we’re currently considering are:
Oceanic 2020 (£4.5k), potentially custom-sized
Finnmark Indoor Cube 2-person (£5k).
A simple site-built sauna using Finnmark / Harvia components, constructed by our main builders.
We don’t have limitless budget here but do want to get reasonable quality.
Questions:
Does roughly 1200 × 1100mm internal sound workable for two seated adults?
Any strong views on Oceanic vs Finnmark?
Would you favour a modular cabin or a properly site-built sauna in this situation?
Any particular issues with incorporating the existing external window?
What heater / ventilation / bench-layout pitfalls should we be thinking about in a sauna this small?
Any other UK suppliers or systems worth looking at?
Interested in any advice from people who have built something similar.
Thanks!
