Overview
The I-Thera-U SAUNA-R is a fold-flat steam sauna tent that builds a 660nm and 850nm red light panel into the same enclosure as the steamer, aimed at anyone who wants a sweat-and-light session at home without plumbing a room for it.
It pairs a 1200W steam generator with a red light grid mounted inside the tent, so light exposure happens during the same session as the steam rather than as a separate step. The pentagonal shape is the seller's answer to the cramped feel of round pop-up sauna tents, and the 450D oxford fabric with thickened steel piping is pitched as a durability upgrade over lighter tents.
- 108 x 660nm and 216 x 850nm LEDs
- 450D oxford fabric with stainless steel piping
- Foldable chair and remote control included
- Interior and exterior storage pockets
Who it's for
It suits renters and small homes since it folds down and needs no built-in plumbing. It is not for anyone who wants exact interior measurements or reviewed reliability before buying.
Pros and cons
- Red light panel built into the tent
- 1200W steamer with 15 heat levels
- Folds flat for storage between uses
- Boil-dry and leak protection included
- No interior dimensions listed for sizing
- Manual water refill for the steamer
Performance notes
The steamer is a 304 stainless steel 1200W unit with a 3L tank, 15 heat levels and a timer up to 90 minutes, with boil-dry and leak protection built in per the listing. The red light grid sits inside the tent so it runs during the same session as the steam, rather than needing the tent opened partway through. The pentagonal shape is meant to add usable interior space over a round tent of the same footprint, though no exact interior measurements are listed.
