Hybrid Sauna Running Costs UK
What You'll Actually Pay
Real electricity costs per session for Finnish, infrared, and combined modes. Plus monthly estimates based on different usage patterns.
How Much Does a Sauna Cost to Run?
Running cost is one of the most common questions we get from buyers. The good news is that a hybrid sauna is genuinely affordable to run, and significantly cheaper than most people expect. The electricity cost per session depends on which heating mode you use, how long you run it, and your current electricity tariff.
We have calculated all costs below using the current UK average electricity rate of approximately 24.5p per kWh (as of early 2026, based on the Ofgem price cap). Your actual costs will vary slightly depending on your tariff and supplier.

| Infrared only | 1.3 to 2.0kW | 30 to 45 min | £0.50 to £0.80 |
| Finnish stove only (2 person) | 4.5kW | 30 to 45 min (inc. heat up) | £1.50 to £2.00 |

How Hybrid Compares to Other Wellness Running Costs
To put sauna running costs in perspective, here is how they compare to other home wellness equipment:
| Equipment | Typical Monthly Running Cost |
|---|---|
| Hot tub (heated 24/7) | £40 to £80 |
| Swim spa (heated 24/7) | £60 to £120 |
| Hybrid sauna (3x weekly) | £12 to £24 |
| Ice bath (chiller unit running) | £15 to £30 |
| Gym membership | £30 to £60 |
A sauna is one of the cheapest wellness products to run because it only uses electricity during active sessions. Unlike a hot tub or swim spa that must maintain temperature 24/7, a sauna heats from cold each time you use it and draws zero power when not in use.
Tips to Reduce Running Costs
Use infrared mode for weekday sessions. Infrared heats up in 10 to 15 minutes and costs under £1 per session. Save the Finnish stove for weekend sessions when you have more time for the full ritual.
Keep the door closed. Every time you open the door, you lose cabin heat and the stove works harder to recover. Get in, close the door, and stay in for the full session.
Insulate your base. Place the sauna on bearers or insulating mats to prevent heat loss through the floor into the ground.
Switch to a time of use tariff. If your energy supplier offers cheaper overnight or off peak rates, schedule your sauna sessions during those windows. Some smart tariffs offer rates as low as 10p per kWh during off peak hours, which would roughly halve the costs shown above.
