Deciding on a Sauna

These days, there are many decisions that a home owner has to make when deciding to install a sauna. For starters, you will need to decide on the specific size; most saunas can comfortably accommodate one to two people, but larger ones can be built. From there, you may want to have some extra amenities installed as well to enhance the experience. This can include anything from a special light package to a stereo system or anything in between. It is also wise to have a thermometer installed in the unit to monitor temperature safely.

Costs to Install a Sauna

The cost to install a sauna in your home can vary greatly depending on how large of a sauna you desire, what kinds of extras are to be installed, the location of the sauna and the specific materials being used. In general, however, you can have a sauna completely installed for around $3,000. 

In general, it is less expensive to install one outdoors, as this can save the home owners and contractors from having to deal with difficult space constraints. Durable woods such as redwood and cedarwood need to be used when installing a sauna outside. Depending on where you get the wood and what type you use, it may increase the cost of the overall installation but will save you a great amount of money in potential repair costs down the road.

All in all, having a sauna installed in your home can be a great investment that can increase your home's resale value while allowing you to reap the immediate health benefits.
