For gyms and boxes

Why CrossFit boxes are adding saunas

There are 900+ CrossFit boxes in the UK, and most of them sell the same thing: the workout. Recovery culture is changing what members expect after it. Across 50 saunas built and 34 operators running, we have built saunas for gyms, venues and operators, and this is the case for putting one at your box: what it does for retention, what it earns, and what it costs each month.

Recovery culture is reshaping gym culture

Five years ago recovery meant a foam roller in the corner. Now your members track their sleep, take cold showers on purpose and talk about heat exposure the way they talk about programming. The demand side has already moved; the question is whether they do their recovery at your box or pay someone else for it.

A sauna on site answers that. It keeps the post-WOD hour inside your four walls, turns a training facility into somewhere members stay, and puts your box on the right side of a habit your community has already adopted.

What it does for a box

Three things, in the order owners tend to feel them:

  • Retention. Cancelling a membership is harder when it is also your sauna membership. The sauna gives members a reason to come on rest days, which is exactly when a box usually loses them.
  • A new revenue line. Sauna access sells as a membership tier, a per-session booking or a recovery add-on, through the booking system you already run.
  • Differentiation. Every box in your area sells coaching and community. Very few sell heat. It is a visible, photographable reason to choose yours.

The community effect matters as much as the money. The sauna bench does for rest days what the whiteboard does for training days: it gives people a reason to stay and talk.

What it costs each month

We build three saunas: the horsebox sauna, the 10ft container sauna and the 20ft container sauna. For a box, the containers are the usual fit: they sit in a car park, yard or outdoor space, arrive built, and are made for high-traffic commercial use.

Financed through Johnson Reed, a sauna starts from around £1,000 a month. Most owners set that against a recovery tier on the membership: the maths is a short conversation once you know how many members would pay a few pounds a week more for heat.

Buy or Partner

There are two routes to a sauna at your box:

  • Buy. From your own funds, or spread the cost from around £1,000 a month through our finance partner, Johnson Reed. You own the asset and keep everything it earns, from the month it arrives.
  • Partner. For select opportunities, the no-capital route. We place and maintain the sauna, you provide the site and the members, and we share what it earns.

This is one decision inside the bigger picture for venues: our complete guide to adding a sauna to your business covers it in full.

The proof: a box that did it

Eastgate CrossFit added one of our container saunas to their facility. The unit went into space they already had, and sauna access folded into the box they already ran.

And they are far from alone in adding heat: our operator map shows the businesses running our saunas across the UK right now.

Sauna Box understood what we needed immediately. The container sauna fits perfectly in our facility and the team were incredibly helpful throughout.

Frequently asked questions

How much does a sauna cost for a gym or CrossFit box?

Financed through Johnson Reed, a commercial sauna starts from around £1,000 a month. You can also buy outright, or partner with us: we place and maintain the sauna, you provide the site, and we share what it earns.

Where does a sauna go at a CrossFit box?

Our 10ft and 20ft container saunas are self-contained units that sit in a car park, yard or outdoor space. They arrive built, so installation is a delivery and a connection rather than a construction project.

How do gyms charge for sauna access?

Most boxes sell it as a recovery tier on the membership, per-session bookings, or both, through the booking system they already use. We work through the pricing with you before the build.
