Testimonials

I’ve been dreaming of a home spa for years, and this store made it happen. I purchased a 2-person infrared sauna, and the build quality is exceptional. The wood smells amazing, and it heats up so much faster than I expected. The customer service team was incredibly patient with all my technical questions during setup!

Sarah J.

Finding a high-quality electric heater for my DIY outdoor sauna was proving difficult until I found these guys. I went with a HUUM Hive model and its great.

Marcus T.

As a marathon runner, recovery is everything. I invested in one of their smaller saunalife outdoor units and It’s been a total game-changer for my muscle soreness.

David M.

I knew nothing about saunas before walking into this process. The Sauna Pro team guided me through the differences between infrared and traditional, helping me find what worked for my budget and space. I ended up with a Leil Como 120. It’s now my favorite place to unplug and de-stress after work.

Jessica W.

We decided to go with the GL6 for our lakeside cabin, and it’s become the centerpiece of the property. The exterior is gorgeous and the craftsmanship is evident in every joint. It looks like a high-end resort feature - truly a five-star experience.

Greg H.

I manage a boutique hotel gym and needed a reliable supplier for our high-traffic sauna. We replaced our old heating unit with a Harvia Virta 20kw. The durability is outstanding, and the temperature control is precise. It’s rare to find a supplier that understands the needs of a commercial facility like they do.
