Reconnect, recharge, unwind & breathe.
Crafted in Lithuania, this sauna draws on generations of Baltic sauna tradition, where quality timber, careful workmanship, and respect for heat and steam are central to the experience. Using time-honoured techniques and carefully selected materials, it was built to deliver a softer, more authentic heat — the way sauna has been experienced for generations.
We also offer high quality professional ice baths with temperature controls so you can be in charge of your ice bath experience, letting go of ‘cold plunge ego’ and immersing yourself in a relaxing and soothing experience.

I used the sauna after a heavy weight session and it was absolutely fantastic, exactly what I needed. The heat was perfect, the environment super clean, and I came out feeling completely refreshed. Can’t recommend Sauna Flo enough if you’re looking for a proper recovery boost.
