How to Build a Sauna Door How to Build a Sauna Door
A sauna door is a very important part of any sauna. Just as the door to a home is inviting, attractive and most of all functional, so should a sauna door. Because of the heat and humidity inside a sauna, your sauna door must be constructed in a manner to withstand these conditions and not be subject to warp. A sauna door can be all wood with insulated core or built with insulated glass. Building a sauna door is not extremely difficult with the right tools and instruction. Follow these steps to build your own sauna door.
Step 1 - Measure and Cut Plywood
A sauna door is smaller than traditional doors because of the fact that the smaller the door, the more effective the sauna will be when maintaining temperature. Measure the plywood to the dimensions of 24 inches x 72 inches. Once you have marked the dimensions on your plywood, use your saw to skillfully cut the door.
Step 2 - Cut In Glass Space
Although a sauna door can be complete wood, you can also add an opening in your plywood for tempered glass so that you may allow more natural light into your sauna. Cut a section in your door to the dimensions of the size glass you want to havein your door.
Step 3 - Measure and Cut Cedar
Cedar is a high quality wood that can withstand the pressure of extreme heat. Measure and cut the cedar to the dimensions of your plywood door. Use your router saw to create tongue and groove ends on your cedar. This will enable your door to be solidly constructed and prevent warp.
Step 4 - Apply Insulation
On the side of the door that you will consider facing inside your sauna, you will want to place a heavy weight aluminum foil on the surface and cut to the dimension of the door ensuring you compensate for the glass window space. The shiny side of the aluminum foil should be facing upwards to reflect the heat from the door and back into the sauna. Once you have the foil in place, use the wood glue sparingly on the opposite side and place against the wood. Allow the glue to dry.
Step 5 - Apply Cedar Panels
Once the insulation is dry, you can now place your cedar panels over the top of the plywood. Using the tongue and groove method, dry fit the panels on the plywood to check for a perfect fit. Once you have determined the fit, apply wood glue to the groove of the panels and place them on the plywood. Once this is done, secure the panels to the plywood. Repeat the action on the opposite side of the door. Your sauna door is pretty heavy at this point.
Step 6 - Apply Hardware
You are now ready to add hardware to your door. For safety reasons, sauna doors open to the outside and not to the inside. Apply your hinges and handles appropriately.
