Lilla Sauna Svinninge: How a Mobile Sauna Is Turning Into a Self-Service Success Story

In the quiet harbor of Svinninge Båtsällskap, just 25 minutes north of Stockholm, something new is warming up. Lilla Sauna, a small independent sauna business, has launched a self-service sauna rental concept, making it possible for anyone to enjoy a traditional Swedish sauna experience by simply booking online and unlocking it with their phone.

Their story begins with a partnership between BastuSpa.se (part of Eldsmedjan.se) and Rentalbuddy.io, combining high-quality mobile saunas with an all-in-one digital booking system.

From Idea to Launch: A Smooth Start

For founder Caoimhghin Schmidt, the idea was simple - bring the joy of sauna to more people without the hassle of staff, schedules, or complicated bookings.

“The process of purchase has been fantastic, and it has been so easy to get started,” says Caoimhghin.

“Rentalbuddy made everything simple — from the setup of digital locks to receiving the first booking notification on my phone.”

The sauna, purchased from Bastuspa.se (part of Eldsmedja), is placed beautifully by the waterfront at Svinninge Båtsällskap, offering visitors and locals a unique way to unwind after a day by the sea.

A Partnership That Opens New Doors

For BastuSpa, this collaboration marks a new chapter in how they sell and deliver their saunas.

“Our partnership with Rentalbuddy really opens up a new, untapped market of self-service sauna sales,” says Patrik Andersson at BastuSpa.

Together, BastuSpa and Rentalbuddy have created a ready-to-launch self-service sauna package - combining physical saunas, digital locks, and online booking - so that anyone can start a sauna rental business in days, not months.

“Many customers want to start small - to try renting out one sauna before building a larger concept. Now, with Rentalbuddy, that’s completely possible.”

About Lilla Sauna

Lilla Sauna is a mobile sauna placed at Svinninge harbor, open for anyone to book online. With Rentalbuddy’s booking system, customers can easily select a time, pay online, and receive a digital code to unlock the sauna.

The self-service setup means the sauna can operate 24/7, even without staff on site — giving the owner more flexibility and customers full freedom.
