If you are shopping for an indoor hot tub, you likely have several questions about where it can be located in your home. One of the more common places that hot tubs are installed indoors is in basements or sunrooms attached to a home.

Often, people will ask if a hot tub can be installed in a bathroom as that can be an ideal room to transform into a spa-like personal oasis.

While, yes, a hot tub can certainly be used in a bathroom there are a number of important factors that you need to review first to ensure that your bathroom will be properly equipped to handle a hot tub as well as support its weight.

In the article below, we will review what you need to consider for installing a hot tub in your bathroom.




In addition to ensuring that your bathroom floor is strong enough to support the weight of your hot tub, what type of flooring you use is incredibly important as well. It may seem surprising, but up to a gallon of water comes out with you when you exit your hot tub. Where does most of this water end up? On your floor.

So it is essential to have a quality flooring material that not only isn’t slippery but also has good drainage when wet. Carpet, wood, and astroturf are not recommended as they will rot from the water spillage. The best flooring option for an indoor hot tub is non-slip tile with a matte finish. Even better is also installing a flooring drain so that any splashed water will not pool on the floor.

Moisture and Ventilation

When the cover is off your hot tub and it is running, your bathroom will become very steamy. It is very important that the walls can handle the moisture without rotting. Concrete and glass are great choices and there are some types of rot-resistant wood and water-resistant drywall that is available.

Another must is having a powerful fan (that isn’t noisy) that is able to suck the humidity out of the bathroom quickly. This will spare your walls from moisture damage or mold and mildew forming. If possible, it also helps if you can crack a window open while soaking in your hot tub to help allow the moisture and humidity to escape.

As bathrooms are typically smaller spaces, a hot tub can cause the room to heat up quickly. Installing a ceiling fan is ideal for improving the air circulation and helping to keep bathers from feeling overheated.


Make sure you consider how you will be able to get your hot tub into your bathroom. You will need to factor in the entire delivery path through your home and ensure that staircases and hallways are wide enough to allow the hot tub to pass through. If you have an existing bathroom it is probably likely that you may need to remove the door or even expand it in order to bring the hot tub into the room. If you are building a new bathroom, make sure that you do not put on the door until after your hot tub has been delivered.


If you have any other questions about putting a hot tub in your bathroom, just ask your local hot tub dealer. They will be able to help guide you every step of the way.
