Thermowood Production is a full-cycle manufacturer. We don't resell, aggregate, or assemble existing products. We create saunas from scratch: we dry the wood, thermally modify it at 215°C, design, manufacture, test, and ship.
This guide will help you choose the perfect sauna from 6 formats, understand thermally modified wood technology, calculate the ROI, and make an informed decision.
This is a process of treating wood at 215 C in an oxygen-free environment. Result:
