Sauna type

Electric saunas

An electric sauna heater warms a basket of stones and is controlled by a thermostat and timer. It's simple to use and needs no fuel store or flue.

Most need a dedicated supply from your consumer unit, and in England that work falls under Part P of the Building Regulations. Use a qualified electrician and ask the builder what supply their heater needs.
