Can a Hot Tub Be Used in a Bathroom?

If you have always dreamed about having an indoor hot tub, you probably have a number of questions about where the best place is to install one in your home. Basements are often used or attached sunrooms, but what about bathrooms? Can a hot tub be used in a bathroom? While it most certainly can, there are a number of really important factors that you need to consider first before making your decision on where to install your indoor hot tub.

Keep reading below to learn about what you need to consider for installing a hot tub in your bathroom in order to create the perfect spa-oasis you have always wanted.

Moisture and Ventilation

Once your hot tub is running and the cover is removed, your bathroom will become very steamy quite quickly. Therefore, you need to make sure that your walls are designed to handle moisture and will not start rotting after repeated exposure from the steam and humidity. The best choices for wall material are concrete, glass, water resistant drywall or rot-resistant wood.

Having a powerful fan and vent that can quickly suck the humidity out of your bathroom is also a must. This will help spare your walls from mold and mildew formation as well as moisture damage. It also helps to have windows in your bathroom that you can open a crack to help allow the humidity to escape. When choosing your fan, make sure that it is a silent one as nothing will ruin your hot tub experience quicker than a noisy, rattly ceiling fan. Having one or two ceiling fans installed will also help circulate the air and help bathers from feeling overheated.


Before you install a hot tub in your bathroom, you need to make sure that your floor is strong enough to support the weight of the hot tub once it is filled with water and bathers.

Another important factor with flooring is what type of flooring is being used. No matter how careful you are, when you step out of your hot tub some water will be coming with you and that water will end up on your floor.

It is necessary to have a quality, slip-resistant flooring that also has good drainage. Carpet, wood, and astroturf are not recommended as they will rot from the water spillage. The recommended option for an indoor hot tub is non-slip tile with a matte finish. As an extra precaution, install a flooring drain so that any splashed water will not pool on the floor.


Another important consideration is how you will get your hot tub from your driveway to your bathroom. You will need to visualize the entire delivery path from the street, to your home and through your house, making sure that all staircases and hallways are wide enough to allow the hot tub to pass through. There is a chance that you may need to remove your bathroom door or even expand it in order to carry the hot tub into the bathroom. For those building a new bathroom, make sure that you do not install the door until after your hot tub has been delivered.

If you have any other questions about installing an indoor hot tub, just ask your local hot tub dealer. They will be able to give you plenty of helpful advice.
