A home sauna may be considered a luxury item by some homebuyers, which can provide a good return on investment. However, whether it increases your home's value ultimately depends on the buyer, as some may not want to take on the extra costs and maintenance associated with heating and upkeep.

Most people will opt to put their home sauna outside near a pool or on a screened-in porch so the heat doesn’t move into the rest of the house. If your house has enough room, you may choose to put it in a bathroom so you can shower right after.

No, you should only choose high-quality wood to build your sauna. Not all types of woods can withstand the pressure from heat or moisture. Only use softwoods, such as cedar and aspen, that are known for absorbing heat and resisting water.

It will take several hours or more to build a sauna. A prefab kit will take anywhere from three to 20 hours to install, depending on complexity and your skill level. If you’re doing a custom build, it can take more than 50 hours—especially if you need to add ventilation, ductwork, and other renovations.
