Frequently Asked Questions

How much does it cost to run a sauna?
The cost depends on the sauna’s wattage and duration of use. For traditional steam saunas like this 4500W unit, usage typically costs between £0.50 and £2.50 per hour. Please consult an Electricity Cost Calculator for precise estimates based on your energy tariff.

What warranties do you offer?
All saunas come with a 1-year warranty on electrical parts and a 2-year warranty on the wooden structure.

Are the saunas easy to assemble and install?
Yes. All units are delivered flat-packed with clear instructions and optional video support. The structure is secured with clamps and screws.

Note: This sauna requires electrical connection to the mains by a certified electrician.

How hot does the sauna get?
This traditional sauna offers an adjustable range from 18°C to 99°C, with timer control from 1 to 99 minutes.

When should I add water to the sauna stones?
Only add water once the stones are fully heated. Adding water too early may reduce steam quality or damage the heating elements.

How can I tell when the stones are hot enough?
Stones should feel intensely hot—without touching. Most heaters include a temperature gauge. Wait until it reaches at least 300°F (approx. 150°C) before adding water.

What type of water should I use?
Use distilled or clean tap water. Avoid hard water with high mineral content, as it may cause build-up on stones or damage the heater over time.

Do I need to worry about mould or moisture?
In very humid environments, keep the sauna interior dry between uses. Otherwise, no special anti-mould treatment is required.

What cable size is needed for power supply?

• For 3000W saunas: 2.5mm² cable

• For 4500W saunas (this model): 4mm² cable
  Always consult a qualified electrician for installation.

Do I need an RCD for this sauna?
Yes. An RCD (Residual Current Device) is recommended for safety. Installation should be done by a licensed electrician.

Is the sauna delivered pre-assembled?
No. It arrives flat-packed for easy transport and assembly. Detailed manuals and optional setup videos are provided.

How long does it take to heat up?
From an ambient temperature of 10°C:

• ~15 minutes to reach 50°C

• ~30 minutes to reach 70°C

Is the exterior timber hot to the touch?
No. The Canadian Hemlock exterior remains warm but safe for contact, even for children.

Can I paint the outside of the sauna?
Yes. The outer surface can be painted using natural wood-safe paints, although it’s typically finished in its natural colour.

What type of wood is used?
This sauna is made from Canadian Hemlock, a durable, low-resin, and aromatic wood ideal for sauna use.

What is the oxygen ionizer and what does it do?
The built-in oxygen ionizer purifies the air inside the sauna by generating negative ions, which may help reduce allergens and enhance comfort.

Are sauna stones included?
Yes. The heater comes with sauna stones—please rinse them thoroughly before first use.

Is the mobile app included or extra?
The mobile app control feature is built-in and included at no additional cost.
