I visited Thermos last Sunday and I noticed it was very clean, and I am a clean-freak :) Perfect cabines, it is a huge place and they have got it all; hairdresser/ restaurant, masseur et cetera. I have seen a lot of sauna's because I travel a lot and have to say Thermos is defenitely worth it. See you soon guys!
Thermos is the oldest and largest gay sauna of Amsterdam. Thermos is open every day from midday till early in the morning. It features 4 floors of gay fun.
The sauna has a swimming pool, whirllpool, steam room, dry sauna, bar and restaurant, smoking lounge and many cabins.
