Run the numbers
Adjust the numbers to match your venue, see the payback beside them, then talk to us about your real site.
From our own operators. This is where we have by far the most data.
A rough guide, not a quote: after 20% VAT and typical running costs (sauna master or staffing, wood or power, cleaning, insurance).
An early estimate from industry conversations. We’re collecting more data, and we’ll work through your own numbers with you.
These numbers are a rough guide. Talk to us about your real site and we will work out the actual figures together.

Before you say yes
A sauna is not a cost centre once it is running. The segment numbers above are what our operators are billing today, from session sales and memberships built around it.
Our operators tell us the same thing again and again: a sauna gives people a reason to return more often, and stay longer once they do.
A sauna changes how a visit feels. It gives people somewhere to talk, recover and unwind, rather than just another piece of equipment on the floor.
Who doesn’t love a sauna? Once someone tries one, they come looking for the next one, and our operators see that pattern every single week.
Per the British Sauna Society, the number of public saunas in the UK has grown from 45 in 2023 to over 200 today. Wellbeing is where UK leisure spending is heading, and venues that move early get to lead it rather than follow.
