From 1st December 2025: Please bring your own bath towel!
Around two million bath and sauna towels are washed at sole uno every year - an effort that has a considerable impact on the environment and resources. By discontinuing the free hand-out, we are working with you to create a sustainable wellness experience.
Thank you for taking this step with us.

"Dear guests of the sole uno. |

It's time for a sustainable change - you can help with your own bath towel.
Questions? We answer them!
Around 2 million cloths are used at sole uno every year. At peak times, over 10,000 pieces have to be washed per day, which requires enormous amounts of water, energy and detergent, causes transportation routes and has a significant impact on the environment. The new regulation significantly reduces the consumption of resources - an important contribution to greater sustainability.
Unfortunately, the requirement to use a maximum of one bath towel and one sauna towel per person is often not adhered to. On average, 4 or more towels are used per stay, which has led to a massive increase in consumption.
Unfortunately, many towels are carelessly left lying around in the recreation and changing areas. The new regulation ensures more order and space - and therefore a more pleasant atmosphere.
From December 1, 2025, free bath and sauna towels will no longer be provided.
Yes, of course. For the sauna, it is important that the cloth is large enough so that all parts of the body that come into contact with the wood have room on it ("no sweat on the wood").
No problem: bath and sauna towels can be borrowed at any time for a fee of CHF 4.50.
