Aspects of installing an indoor hot tub

Where to place a hot tub indoors

The first step is to choose a suitable place for the jacuzzi. If you are still not sure where to place the hot tub, you can read our step-by-step guide on How to Pick & Prepare a Place for a Hot Tub.

The main options for the location of the jacuzzi at home: 

Some conditions that apply when you wish to install a jacuzzi at home.

In addition to installing a jacuzzi, you need to ensure that your home is safe and sound — without mold, broken floors, balconies, or doorways.

Problems you can avoid:

1. Moisture in the room with a hot tub

Indoor Hot Tubs
Good ventilation will help to easily control the humidity in the room

Due to increased humidity, floor and wall coverings can deteriorate, and mold can develop. To prevent this from happening, install a jacuzzi in a room with a good ventilation fan. You can choose silent models or higher power models.

Their installation will take you no more than 20 minutes, the cost of these models is also low — from $ 15.

To regulate the microclimate, you may need a heater — if you raise the temperature in the room, there will be much less condensation. A dehumidifier will help to control and regulate the humidity level.

    If you are just doing repairs or want to put a jacuzzi in a separate room, then choose moisture-resistant materials for decoration. For example, they can be ordinary tiles (such as in your bathroom), moisture-resistant wood types, concrete coating, and moisture-resistant paints are also suitable.

If you have a spacious home, you can simply place the jacuzzi in your bathroom.

Choose waterproof materials for your jacuzzi room

2. The floor crashed under the weight of the jacuzzi.

The lightest inflatable hot tubs usually weigh from 50 pounds, filled with water they will weigh from 1,500 lbs. But your home relax station is not much more difficult to operate than a regular bathtub.

Crash in a house or apartment

According to U.S. residential building codes, the permissible floor load in a living room may be 40 Lb / ft².

To calculate the load for any bathtub, jacuzzi, or any indoor hot tub, you need to divide its area by weight.

For example, the 4-seater round Jacuzzi SaluSpa Miami has an area of ​​40 ft² and a weight (80% full of water) of 1,531.3 lbs. Its load is 1531.3 / 40 = 38.69 Lb / ft² which corresponds to the declared standards. However, if at least 1 person is in it, the load will be about 44 Lb / ft².

So if you are renting a home, you should talk to the landlord before installing the jacuzzi.

    Since the design of each house and balcony is unique, before installing a hot tub you must necessarily request information from the homeowner (if you are renting a home) – technical information must be provided in the contract – namely, the maximum load on the floors in the rooms of your house.

If you want to install a jacuzzi in your own home, then consult with a technical architect before starting work. 

There are some generally accepted load standards in residential premises (According to U.S. residential building codes):

Bedroom – 30 Lb/ft.
Living rooms – 40 Lb/ft.
Balcony – from 30 to 100 Lb/ft.

* In the bathroom, the floor structure is likely to be reinforced

In any case, we strongly recommend that you calculate this in advance, and not just google it on the Internet.

For the convenience of calculations, you can always use our calculator and understand where it’s better to place the jacuzzi. 

Here are the general statistics we will use to calculate floor support:

  • Weight of Empty Hot Tub = Varies depending on the chosen model
  • 1 Gallon of Water = 8.34 lbs
  • Average Weight of Person = 185 lbs
  • Square Feet of Hot Tub = Varies depending on the chosen model
    — 3,14*radius^2 [round hot tub]
    — Length*Width [other forms]
[Weight of Hot Tub + (Number of Gallons of Water x 8.34 lbs) + (Number of People Spa Can Seat x 185 lbs)] / # of Square Feet of Hot Tub = Pounds Per Square Foot

Crash on the balcony

If you have a balcony, then it’s most likely your relaxation spot. And why shouldn’t it be? To relax in the evening in the fresh air and with a beautiful view in front of you is always pleasant and healthy.

According to U.S. residential building codes, the permissible floor load on the balcony can be from 30 Lb/ft² or more. Before installation, ask technical specialists what kind of load the floors on your balcony can withstand otherwise get ready for an extraordinary dose of “adventure”.

The foundation of the house will perfectly support the weight of a medium and large jacuzzi. Remember that the finishing materials there need to be moisture-resistant. In such rooms, you also need sufficient ventilation to remove excess moisture.

With the help of their tips, and in just 5-10 minutes you will understand the installation, cleaning, and other maintenance requirements of the hot tub. Moreover, you will not lose money and waste time due to the improper installation of a new jacuzzi.
