Kaggeholms Slott sits on an island in Lake Mälaren outside Ekerö. It's one of those places that's hard to describe — you understand it better when you're there, with Mälaren's still water all around and the castle in the background.
The sauna is placed directly by the water — less than ten metres to the cold bath in the lake. The sauna door opens towards the water. Step out, step in. Himalayan salt wall and smooth self-service. Book when you like, arrive, enjoy on your own terms.
Choose location, date and time directly on the website. Alone or with friends — you decide.
Pay by card. You get a confirmation and a personal access code for the sauna by email.
Arrive, enter your code and step in. The sauna is preheated and ready. Your recovery session starts now.
Specifications
Digital access
Entry via a personal one-time code. No key, no staff — you arrive and step in at your booked time.
Pre-heated on arrival
The sauna is heated and ready when you arrive. You never have to wait — the warmth is already there.
Leave it as you found it
A mop is on site — a quick sweep of the floor and take your rubbish with you. Takes two minutes and keeps it nice for the next person.
From our earlier guests in Stockholm
"An amazing sauna — a little oasis in the heart of the city. Super well priced given its location and it has a great vibe. The amenities were excellent. 10/10 — I would recommend it to anyone living in or visiting Stockholm!"
Victor H.
"Booked private sauna for six folks. The hour of hot and steamy time broken up by cold plunges was awesome. Rooftop is a good vibe and the showers were lux. Everybody left relaxed and happy."
David E.
"Very central and convenient. The sauna itself was great with an easy process for access. There are essential oils for you to use — a really nice touch."
