I've worked with Jayson (the owner) on about a half dozen builds now, he has always been extremely responsive, professional as well as fair and reasonable. I could not recommend BW more strongly.

BW Custom Sauna Builders | Outdoor, Backyard & Mobile Saunas

Simply Unbeatable Quality Craftsmanship

Our saunas start with a sturdy 2×4 frame, exterior OSBTyvek, and all-weather metal siding. On the inside, we use insulation on all walls, including the floor if elevated. This is followed by an interior metal heat shield, cedar or pine spacers to prevent moisture traps, and the finished cedar. Together this brings the highest in professional sauna design that will look good and last a lifetime.
