DIY Home Sauna

A home sauna can be a great way to enjoy a relaxing moment after work or just to help increase your skin’s health. No matter what you use a sauna for, creating your own sauna is easier than you think. Use these simple tips and techniques for creating a DIY sauna and create your own relaxing day spa at home!

Step One: Installing the Plumbing

This part of the project is the most important part of a DIY sauna. No matter what size, location or style of sauna you plan on building, you’ll need a drain and a hot water supply installed by a professional plumber. You also might need to have your plumber and an electrician install the sauna heater as well, depending upon the style and design you purchase.

Step Two: Flooring Membrane

This is the easy part. A simple plastic shower pan membrane can be used to cover the drain and flooring of the sauna. Spread the liner onto the floor so that each side of the membrane covers the walls at least 6″ or more. Cut a hole around the drain tight enough so that the drain cover can seal tightly around the membrane. Use only galvanized fasteners to secure the shower pan to prevent corrosion later on down the road.

Step Three: Concrete

Adding a concrete floor over the membrane is simple. Mix a bag of ready-mix concrete in a wheelbarrow and use a bucket to transport the goods to the sauna floor. Spread the mix onto the flooring using a concrete trowel. You’ll need to pour a pad at least 3 ½” thick. Use a 2×4 to screed the mix flat. Raise the sides of the concrete higher than the drain so water flows towards the drain and doesn’t leave any puddles. Use a push broom to create a textured non-slip finish just before the concrete hardens for good.

Step Four: Insulation

Insulate the room’s walls using a mold resistant insulation. Seal the exterior of the insulation with a plastic vapor barrier. Be sure to use galvanized fasteners to prevent any rusting later on. Seal the vapor barriers gaps with a silicone caulk.

Step Five: Cedar Wall Planks

Lining the walls and ceiling with tongue and groove cedar planks is easy and fun. Simply measure between the two walls and make a few cuts using a miter saw. Leave a small ¼” gap in the corners to allow for expansion and contraction. Use a 1×2 or 1×4 trim piece of cedar to close the corners up. Add a small cedar bench in each corner for the perfect seating area. Be sure to use galvanized or zinc plated fasteners to prevent rusting from the heavy moisture and add a non-toxic finish. Now you’re ready to enjoy your new sauna!
