Opening this autumn.

The sauna is being built right now. Rather than wait until it’s finished to start taking dates, we’ve opened pre-booking, so the first weekends and the first sessions are already up for grabs.

Be one of the first in.

Two ways to book, both open before we open. Your card is held, not charged, until we’ve confirmed the date.

Private hire

Your weekend. Your sauna.

We tow the sauna to you and set it up, so a garden, a field or a yard becomes the warmest place on the coast for a weekend.

The experience

Heat. Cold. Repeat.

  1. 01

    Get hot

    Fifteen minutes on the top bench. Long enough to stop thinking about your inbox.

  2. 02

    Get cold

    Straight into the plunge. It is a shock, and then it is the best part.

  3. 03

    Go again

    Sit outside. Talk nonsense. Warm up and do the whole thing twice more.

Inside the Bosham Sauna build: timber-lined walls and ceiling, a long window and the bench frame going in.

The build

Built in Bosham.

Timber is up, the benches are going in and the glass is fitted. What’s left is the slow, fussy part: the stove, the plunge, the water, the lights.

We’re doing it properly rather than quickly, and we’re posting the whole thing as it happens.

Pre-booking

Pre-booking, without the uncertainty.

You’re booking something that isn’t finished yet, so we’ve set it up to take as little on trust as possible.

  1. 01

    Choose your date

    Pick a date that suits you. We only show the ones that are still free.

  2. 02

    Authorise, don't pay

    We place a hold on your card for the reservation amount. Nothing leaves your account yet.

  3. 03

    We confirm within 48 hours

    If we can take it, the hold is charged and your date is yours. If we can't, it's released and you pay nothing.

Private hire is delivered to your address at weekends. Group hire is two hours at CrossFit Bosham. Either way, the remaining balance is taken automatically from the same card closer to the date, and we’ll tell you before it happens.

Bosham, West Sussex

Sauna feels better by the water.

Bosham is a tidal village where the road floods twice a day and the locals still park on it. There are worse places to sit in a hot room.

Our home is a short walk inland at CrossFit Bosham — not on the shore itself, but close enough that the walk down afterwards is part of it.

Why anyone sits in a hot room.

Switch off
No phone. Nowhere else to be for an hour.
Recover
After the water, the gym, or a long week.
Reconnect
The best conversations happen in the heat.
Reset
Walk out lighter than you walked in.

Opening Autumn 2026
