The Mobile Hot Box is Sauna Del Soul’s fully self-contained, wood-fired sauna — designed to bring authentic sauna experiences to unique outdoor locations across Cornwall.

Built around simplicity and warmth, the Mobile Hot Box allows us to host guided sauna sessions in gardens, by the sea, at events, and alongside existing venues.

Everything is brought to site, set up, and run by us — creating a calm, contained sauna space wherever it’s placed.

Inspired by the mobile saunas of Finland, sessions inside the Mobile Hot Box are slow, intentional, and sensory. Heat is introduced gradually, and each session may include salt and botanical steam infusions, shaping the atmosphere and encouraging relaxation, connection, and presence.
The sauna comfortably hosts small groups of 10, making each session feel personal and unrushed.

 

Whether used for private bookings, pop-up events, or special collaborations, the Mobile Hot Box offers a flexible way to experience wood-fired sauna in nature.

All sessions are supervised, with safety briefings given before entry. The Mobile Hot Box is fully insured and operated with care for both guests and the surrounding environment.
