FAQ
Does the sauna need professional installation, or can I build it myself?
Most of our thermowood saunas are designed for self-assembly and arrive with detailed instructions. Many customers choose to build the sauna themselves or with the help of a general contractor. However, the electrical connection for the sauna heater must be completed by a qualified electrician.
Do I need an electrician to install the heater?
Yes. Sauna heaters require a dedicated electrical connection and must be installed by a suitably qualified electrician in accordance with local electrical regulations and the manufacturer’s instructions.
Can the sauna be installed outdoors year-round in UK weather?
Yes. Thermowood is specifically designed for outdoor use and performs very well in changing weather conditions. Proper installation, ventilation, and routine maintenance will help maximise the lifespan of the sauna.
Does the thermowood need regular treatment or maintenance?
Thermowood is naturally durable and more stable than untreated timber. Exterior surfaces can be treated periodically to maintain the desired appearance, especially if you wish to reduce natural weathering or colour fading over time.
How long does it take for the sauna to heat up?
Most saunas typically reach operating temperature within approximately 20-30 minutes depending on the heater size, outdoor temperature, insulation, and desired heat level.
What base or surface does the sauna need to sit on?
The sauna should be installed on a stable, level, and well-drained base such as concrete, paving slabs, decking, or another suitable structural surface capable of supporting the weight of the sauna.
How is the sauna delivered, and will it fit through side access or gates?
Saunas are delivered via kerbside freight delivery in flat-pack form for assembly on site. Before ordering, customers should ensure there is suitable access for delivery vehicles and sufficient space to move the packaged components to the installation location.
What are the running costs?
A traditional home sauna usually uses a 3 to 9 kW electric heater and costs around £0.10 to £0.30 per kWh in the UK. This means running costs range from about £0.30 per hour for a 3 kW heater to £0.90 per hour for a 9 kW heater. Preheating typically takes 30 to 45 minutes, which adds to the overall cost depending on how often and how long the sauna is used.
Where are these saunas manufactured?
