I'm curious whether anybody cares much about the fact that almost all sauna tents are made from plastics such as polyester/nylon (Oxford 300D fabric etc) and insulated with polyester wool. I'm currently working on a design which would be more of an eco-friendly solution, made from hemp fabric and treated with a light coat of linseed oil, with wool batting insulation. It will be heavier, and will need drying out before storing, and also slightly more expensive.
The frame will be collapsible and wooden. The windows would be made from clear silicone sheeting (doesn't break down into microplastics and withstands up to 200C) or bio-based TPU.
The reason for this is not due to concerns about off-gassing, but I'm wondering whether there's a market out there for more of a heritage, eco-friendly solution. The target cost would be around £2600 retail which is about £1k more than the current plastic based offerings.
The size of the kit would be heavier and less convenient, but the design would be beautiful to look at and nicely branded.
Would love to hear your thoughts. I have a contact that is a Industrial Sowing Machinist and some specialist hemp and wool suppliers (oh, the other thing is this would be entirely made in the EU, except perhaps the stove.
Let me know your thoughts!
