Popup Sauna Cham

Behind Popup Sauna is Popup Sauna GmbH from Zug: Ville Heimgartner, who has known sauna culture since childhood through his Finnish roots, founded it with Tobias Müller and Marco Späni. It started in autumn 2023 with two barrel saunas at the Strandbad Seeweg lido in Cham — Popup Saunas now stand on seven lakes in Central Switzerland. In Cham, two saunas of the new, in-house developed model with underfloor heating and wider benches have been in use since the 2026/27 season.

You don’t book a spot but the whole sauna: during the booked time it belongs exclusively to your group. The panoramic window offers views of the Zugerberg, the Rigi and the Central Swiss Alps, and for cooling off your own bathing jetty leads straight into Lake Zug. In winter the lido is accessible only to sauna guests — there is no staff, and the gate opens via PIN code exactly within the booked time slot.

At least two hours are recommended. Bring swimwear, two bath towels, a bathrobe, bathing slippers and something to drink; the showers at the lido are not heated in winter, and the public toilets are by the main entrance. For the Aufguss session, lake water from the bucket provided is used — swimming in the lake is unsupervised and at your own risk.
