Heartwood Saunas

Heartwood Saunas takes on commissioned sauna projects for private estates, retreats and commercial wellness spaces, working from a Welsh base in Machynlleth. Alongside the bespoke commission service there’s a made-to-order Signature Collection — a smaller set of design-led models for homeowners who want something close to off-the-shelf without losing the craft feel. The team also builds the Supra Shower as a complementary product, and treats materials and sustainability as a core part of the brief. Pitched at the high end of the market and best suited to projects where the sauna has to look as considered as the rest of the architecture.
