Materials
Our barrel saunas are crafted from continuous lengths of thermally treated traditional Finnish spruce — a timber renowned for its strength, durability, and natural resistance to decay.
Thermal treatment not only enhances the wood’s longevity but also improves performance — offering 25–30% better insulation than cedar. This helps your sauna retain heat more efficiently, resulting in faster heat-up times and lower energy use.
At Bayther, we never use glues or splicing techniques in the construction of our saunas—just solid timber, crafted with care. Our thermally treated Finnish spruce is naturally durable and requires no fumigation with harmful or carcinogenic chemicals during import, ensuring a clean, non-toxic sauna experience.
All of our fixings are stainless steel designed to endure New Zealand's toughest weather conditions.
We use clear 8mm heat resistant tempered glass for all of our Sauna doors.
