Provisional score: Basic
This is a baseline, not a full rating. We scored it with our usual method against the luxury saunas we list (every Sweaty Yeti model is over $20,000), and anything Sweaty Yeti doesn't publish scores zero. Its heater kW, maximum temperature, warranty terms and wall thickness aren't published, so the score can only go up once they are. Confidence: low. It appears in Find My Sauna and our luxury rankings, labeled provisional. See its full scorecard.
| Category | Score | Why |
|---|---|---|
| Construction & durability | Left out | Wall thickness not published; most luxury saunas don't publish it either, so it's left out |
| Value | 21 / 100 | Compared with luxury saunas (over $20,000) |
| Heating | 0 / 100 | Max temperature and heater kW not published, so it scores zero |
| Warranty & support | 0 / 100 | Warranty terms not published, so it scores zero |
| Installation | 100 / 100 | Hardwired, like every luxury sauna we list |
| Space & capacity | 80 / 100 | Seat count only (our scale tops out at 6); the footprint includes every room, so it isn't used for roominess |
