HolzerSauna HotBox — Mietsauna beim Kurhaus am Sarnersee

The HotBox 1.0 from 2024 is the newest and smallest sauna of the HolzerSauna association from Sachseln, which rents out wood-fired saunas privately around the Sarnersee. It stands on a small bathing area behind the «Seehaus» of the Hotel Kurhaus am Sarnersee in Wilen, right on the water.

As with all HolzerSaunas, it is just sauna and lake — no electricity, no running water, no shower. Guests light the wood stove themselves; the roughly 30 minutes of heating time are not charged. The HotBox window looks out over the lake, and cooling off is done via the bathing ladder directly into the Sarnersee; two outdoor cabins are available at the bathing area for changing.

Until the evening, access is through the hotel’s main entrance, by lift to the lake level and through the bistro onto the terrace, from where a staircase leads down to the lake; later in the evening via an outdoor staircase about 40 metres from the hotel and the lakeside path. In summer, hotel guests also use the bathing area — at those times, only jump into the lake wearing swimwear and leave the area after the booked slot. Bring along: bath towels, bathrobe, flip-flops, drinks and a small lamp.
