Our Story
PortaSauna began in Portsmouth with two friends, Jordan and Harry, and a mission to make saunas accessible to everyone.
What started as an early prototype in a back garden has grown into a community of thousands, all united by the same love of heat, cold and the outdoors.

🔹 Formaldehyde (HCHO) – Confirming no off-gassing from materials.
🔹 AQI (Air Quality Index) Particles – Measuring overall air purity.
Why is this important? These tests guarantee that the air inside the sauna remains safe to breathe at high temperatures, making PortaSauna HEX a chemical-free, safe, and health-conscious sauna option for regular use.

Absolutely love our PortaSauna. It has exceeded all of my expectations in terms of quality and the experience of using a sauna tent. I wasn’t totally sure about using a tent but it heats up quickly and we’ve managed to hold it at 80+ degrees without any bother....
SO MUCH BETTER THAN A STANDARD SAUNA! I am a founding member of beach babes Weymouth, a women’s sea swimming group. We had our first porta sauna experience this morning and I can honestly say it was amazing! It was set up on the beach so you have the view and it the window as well as having the stones under your feet...
Amazing Amazing. The sauna looks great. Materials are very high quality and sauna feels sturdy. Very easy to put up and down as needed. I personally really love that is wood-fired. Amazing purchase!
Amazing Sauna Highly recommend Soo good to meet Harry and Sam yesterday , so impressed with the Sauna , it was hotter than the electric one we have at home . Fabulous experience getting out of the hot Sauna straight into the sea .Would highly recommend....
Game changer!! The PortaSauna could be a game changer. As a wellness practitioner, the ease with which this can be set up and taken down has broadened the scope of my own therapeutic practice significantly - contrast therapy on the go!! The product is of exceptionally high quality - the materials of the tent very strong, the stove is superb. I’ve had mine up to 80C in less than half an hour. It takes about 10 minutes to be fully set up...
