Different types of indoor saunas?

There are many different types of saunas out there but here are some of the most popular ones:

1. Infrared sauna

Infrared saunas are becoming really popular due to their health benefits. Infrared saunas use infrared heaters that produce infrared rays.

These rays penetrate your skin and promote blood circulation. In addition, they help to remove toxins from your body, improve your immune system, and relieve pain.

The only downside is being expensive compared to other types of saunas. But if you are looking for a sauna with lots of health benefits, an infrared sauna is the way to go.

Wood-burning saunas are considered traditional saunas because they use traditional methods to produce heat. A traditional sauna uses wood-burning stoves to heat up the rocks. The steam is then circulated throughout the room using a fan.

The main advantage of wood-burning saunas is that they are very efficient in heating up the room. However, they require more maintenance than other types of saunas and take longer to heat up.

3. Electric saunas

An electric sauna is a dry sauna that produces dry heat through its electrical heating element. Electric saunas are very popular because they are easy to install and use. They are also more affordable than other types of saunas.

The main disadvantage of electric saunas is that they use electricity to generate heat so your electric bills might be higher. Other than that, electric saunas are a great choice if you are looking for an easy-to-install sauna.

Lastly, we have portable saunas. As the name suggests, portable saunas are easy to move around and can be used both indoors and outdoors. They are usually made of fabric or plastic and have a small heating element inside.

These are basically pre-built saunas that are made for people who want an easy and convenient way to enjoy a sauna without having to build one from scratch.
