Indoor Hot Tub Installation Ideas

There may be many reasons for choosing to install a hot tub indoors.  You may like the idea of the extra privacy offered by an indoor hot tub.  You may live in an area that gets so much cold weather that you couldn’t see yourself walking outside even if it meant sitting in warm and soothing waters upon arrival.  Or you might have a house with a design that facilitates an indoor hot tub much better than an outdoor one.  Whatever your reasons for choosing an indoor hot tub, there are some special considerations you’ll need to keep in mind when it comes to its installation.

Will the Tub Fit?

You may be surprised to know that it’s quite a common occurrence for indoor hot tub buyers to not check if their hot tub will fit comfortably inside their room of choice or if it will even be able to get through the door in the first place.  For those who are in the process of building their home, this might not be a problem as the hot tub can be installed before the walls are even finished, but for those who are planning to install a hot tub in an existing home, measuring carefully should be the first order of business.

Flooring and Drainage

No matter how careful you are, there will always be spillage when it comes to a hot tub.  Even if you don’t plan on splashing around or having water fights, you will carry a significant amount of water with you each time you get out of the tub.  It’s therefore imperative that your flooring can handle getting soaked.  You don’t want to have carpet or wood that cannot withstand the effects of pooling water.  Having a drain in the floor with proper grading is incredibly helpful.  You’ll also need to ensure your floor can handle the weight of a full hot tub.  Prevent any future surprises by studying the room’s flooring carefully before installation.

Water Source

If you’re installing a portable hot tub, once your tub is full, it will function without the need for any external plumbing.  However you need to get the tub filled with water in the first place.  Having easy access to a water source will be important.  You won’t want to be filling your hot tub by transporting buckets from your kitchen or bathroom the whole day.  If you can, install a spigot beforehand or choose a room that already has one.


Moisture and humidity are facts of life with indoor hot tubs.  You’ll need a method (or few) for dealing with this.  Ensure the room is able to deal with humidity by installing vapour barriers to protect your wall framing from rotting.  Use materials such as glass, concrete or cedar that are resistant to rot.  And make sure you have an exhaust fan that can effectively deal with excess humidity.  You might also want to consider a ceiling fan to help with temperature and humidity control.
