We cost less. Here's exactly why.

Not thinner walls. Not a smaller heater. Not a shorter warranty. We own the crating, the freight, and the last mile, the three handoffs where every other brand pays a margin and passes it to you. Removing them took us four years. It took nothing out of the sauna.

Best thing we've added to the house

Genuinely the best purchase we've made this year. Assembly took an afternoon and the build quality is way better than I expected for the price. Two months in and we're using it almost every evening.

Nervous online, glad I did it

I was hesitant buying something like this online but it's exactly as described. Heats up fast, holds temperature really well, and it looks even better in person than in the photos.

Olivia M. Verified buyer · 1 month ago

Feels far more premium than the price

Solid frame, clean finish, and the wood smells incredible when it warms up. Delivery was on time and the setup instructions were actually clear for once. Highly recommend.

Colder months are sorted

Bought it dreading winter and now I kind of look forward to it. Easy to run, cheap to heat compared to what I feared, and the kids think it's the coolest thing we own. No regrets.
