Indoor Hot Tubs

Hire a Professional. It Will Save You Money in the Long Run.

There are many things to consider when thinking of adding an indoor hot tub to your home. The benefits of an indoor version are you do not have to bank on the weather, there are no leaves and bird droppings which get into it and of course there is the privacy. An indoor hot tub party will be quite different than an outdoor hot tub party, where the neighbors may be close by. That said, the key to a successful indoor hot tub installation is based on many considerations:

Professional Advice:

If you are seriously considering an indoor hot tub you need a professional to come in who knows: design, building requirements, ventilation and has experience with different hot tub models and their pros and cons. Without question this step is not an option it is a must.


A hot tub without water weighs on average 800 pounds without water and over 2,000 pounds with water. These are huge strains on your home's structure.

Humidity & Evaporation:

An indoor hot tub contractor should be able to tell you the best way to keep your home healthy and resistant to mold and mildew. There are five factors to consider when figuring out the best or feasible location:

  • Air Temperature
  • Water Temperature
  • Surface Area of the Water
  • Humidity of the Room
  • Splashing Water Features

After accessing these things the hot tub installer will create a plan for the indoor hot tub by using dehumidifiers, air-exchange ventilation and insulated covers. He will also plan for structural vapor barriers to protect walls, ceilings and to discourage the freezing and thawing of outside walls.

Spa Drainage & Indoor Hot Tub Flooring:

The proper flooring can make all the difference in the world. Remember the commercials of bacteria in carpet fibers, well, imagine the bacteria of flooring that is not bacteria resistant and gets wet. Also, think of drainage. Let's say for example, you put down some fantastic, Italian handmade tile. Everyone is in awe of its beauty and you think you've done the right thing to ensure bacteria are kept to a minimum. You can sit back and enjoy the masterpiece...except, the water may absorb into the tile over time and then the floor will crack and underneath the floor (if not correctly installed) will be a breeding ground for bacteria.


Think about what else you want in the room. Is it conducive to humid conditions? Esthetically, couches would look great, but they absorb moisture and do you want wet bodies on it? What about a sauna? What about rock gardens? Plants? A dining area? Plan in advance, every single aspect and ask your professional for advice. It could play a huge role in ventilation, etc. You really don't want to find out after the work is done that building an indoor hot tub was a bad idea. One other thing to consider: will the hot tub fit through the door?
