Imagine taking a sauna on a floating deck in the middle of Lake Vänern - surrounded by open water, sky, and silence. In Mariestad, Sweden, that dream has become a reality.


Bastuflotten Mariestad is a perfect example of how local creativity and smart digitalization can combine to create something sustainable, accessible, and profitable.

Anchored near Mariestad’s guest harbor, the sauna raft offers visitors - locals, winter bathers, and tourists alike - the chance to relax, take a dip, and enjoy the peaceful views over Vänern all year round.

From Vision to Reality with Rentalbuddy

Behind Bastuflotten Mariestad are local entrepreneurs with a clear goal:

“We wanted to create something beautiful and accessible for everyone — without having to be there in person to handle every booking.”

To make that possible, they needed a sauna booking system that could automate everything — from online bookings and payments to digital access control.

They chose Rentalbuddy, the all-in-one booking system that made it easy to launch a self-service sauna rental without technical complexity. By using Rentalbuddy, the team could focus on delivering the perfect sauna experience — while the system handled all the logistics.




How Rentalbuddy’s Sauna Booking System Works

Rentalbuddy automates every step of the rental process, enabling Bastuflotten Mariestad to stay open 24/7 — without staff on site:

  1. Book online – customers select a date and time at bastuflottenmariestad.com

  2. Pay instantly – secure payments are processed through Stripe

  3. Receive digital access code – a time-limited code is automatically sent to unlock the sauna

  4. Enjoy the experience – everything happens seamlessly, without manual administration


With this setup, Bastuflotten Mariestad runs efficiently, providing full flexibility for guests and minimal workload for the owners — the perfect example of a modern, self-service sauna business.

“We’re super happy with Rentalbuddy!”

“We want to thank Emil for all his help and support — he’s been amazing! We’re extremely satisfied with Rentalbuddy and also grateful for the support from our local municipality that helped make this idea a reality.” - Bastuflotten Mariestad


From Sketch to Sauna

Before construction began, the team built a mini model to test different plank types and design details — the foundation for what would become their self-service sauna in Mariestad.


Step by step, the floating sauna on Lake Vänern took shape. Every joint, beam, and board was crafted locally, combining traditional handiwork with modern thinking.


Today, the finished sauna stands as proof that great ideas — supported by the right digital tools like Rentalbuddy’s sauna booking system for self-service rentals — can move from model to masterpiece.
