01 · Features

Built to run a community sauna.

Membership systems book nothing. Booking systems know nothing about membership. Bastu does both.

Membership sets the price

A guest pays full. A member pays theirs. Nobody works it out by hand.

Points that reward engagement

Members earn points on every booking, and volunteer hours turn into credits to bathe with. Your rules, your name for the points.

Rituals and events

Aufguss, a full-moon bathe, a guided evening. Put it up as an event with its own places and its own price.

And the rest of the surface

03 · Background

What is a community sauna?

A sauna open to the public, where people come together around the ritual of sauna and bathing — in shared sessions or private ones. Close to nature, and close to each other. The tradition is Scandinavian and very old, and it is coming back.

Bastu was built for Umeå Kallbadsförening, who needed something nobody sold: members and public in one calendar at different prices, with volunteer hours paying their way back. It did not exist on the market. So we built it — and it has run for real every week since.
