Mini-Cube Sauna - 2 Person

The sauna itself was easy to build. The screws were cheap and break easily. Definitely need a fan inside to keep the air evenly hot. It’s cold from knee level and down to feet. I really wish there was some sort of drip tray that goes underneath the sauna to catch the sweat. If the sauna is outside no need for a drip tray. My sauna is inside and my floor gets sweat all over it. I had to have someone make me a sheet metal tray to go underneath and collect the sweat. Other than that the sauna is very good quality and the heater works great. It keeps the heat inside the sauna and doesn’t really leak out at all unless you leave the door open.

I have had my Mini-cube for a few months and have been impressed with the quality and effect it’s had on my health. Using it post workout has been a wonderful addition to my daily routine. I love the remote aspect of warm up. It’s perfect to activate it during my post workout stretching. I can get home, grab my water and towel and head outside to the sauna. I can’t recommend it enough.

Mini-Cube Sauna - 2 Person

We purchased our mini cube sauna in October for our backyard in Denver and haven’t looked back. We’ve used it every single night. Once the sauna is out of the crate, the build goes by pretty quickly. With 3-4 people to help, it took about 8 hours including installing the shingles - the shingles were honestly the toughest part. The instructions were pretty straight forward but we did install some pieces incorrectly and couldn’t go back and change it resulting in some improvising later on. A couple things we wish were clearer, the back wall (a sticker labeling front vs back), the venting pieces (bottom or right side and number of exact placement), and pre drilled holes for where exactly the heater should be mounted. Some nice to haves would have been some extra screws and I wish we were able to pick our own accessories - we’ll never use the mat or hat and would have opted for an additional hook or palm oil. Something to think about when considering any of the saunas, the electrical installation cost. We thought at the most it would cost $2k, it ended up costing $4k. We also ended up painting the outside of ours black including the step and it’s absolutely stunning! We’d 100% purchase another sauna from Redwood again.

Mini-Cube Sauna - 2 Person

Received my Outdoor, 2 Person Mini Cube Sauna on Thursday, built it on Saturday. It took me & a friend around 7 hours to complete, including the optional shingles and heater guard. Directions were easy to follow and the build went pretty smoothly. Had one question, reached out to Redwood customer service. Their response was quick and they resolved my issue. Now waiting on the electrician to complete the hookup. It is a beautiful addition to my yard and I can't wait to experience sauna life. I would recommend Redwood Outdoors to anyone considering a sauna. Next up is the cold plunge.
