Sauna Repair
Basic sauna problems: If your sauna's heater unit isn't working at all, test it first, but if it is still malfunctioning, you'll probably need to have it replaced. When the water in your unit is too hot or too cold, it's probably a malfunctioning thermostat.
If the wood paneling in your unit is in need of repair, you might want to find out what caused the problem. If it's from a leak in your unit, make sure to get the leak (and the paneling) fixed. Kiln-dried wood works best in spas and saunas.
Faulty insulation, vapor barrier or door seal problems should be fixed by a professional. Not dealing with these in a timely manner will lead to more problems with your unit.
