Preparing the site for your hot tub

Before the hot tub is delivered to your home, ensure that the chosen site in your back yard, or on the deck, is prepared in advance:

Size & intimacy of the hot tub

First of all, check to see if you have an area large enough to accommodate a hot tub. You have to plan the location not just for the hot tub itself, but must also have enough space around the tub to accommodate a shelter or gazebo, steps to access the tub, and any hot tub equipment that you may wish to add.

If there are neighbours close by, or if you build a hot tub in a communal area, choose a space isolated enough to install the hot tub. First, this will allow privacy for hot tub users, and secondly, it will maintain your relationship with the neighbourhood as a hot tub is relatively noisy when in use. Think about it!

Weight and Humidity

Ensure that the ground can support the weight, vibration and humidity of the hot tub. On average, a hot tub weighs between 250 and 500 kg, empty, and this weight can exceed 2 tons when filled with water. This is considerable, especially if you plan on building the hot tub on a patio or an elevated deck.

Also note that a hot tub consists of several pumps with 2 to 3 hp each, to allow the water to circulate and supply a sufficient amount of force to power the jets. This causes vibrations in the ground and should be anticipated.

Finally, be aware that the hot tub will release a lot of humidity which may cause damage if you place the tub under, or too close to a surface that is sensitive to humidity, for example, wood.

Installing the hot tub

Once you have prepared the ground, you will need to install the hot tub in two stages:

Electrical Connections

All hot tubs need electricity to operate. Note that Swim Spas need a more powerful electrical supply; however, your SIMA hot tub store recommends that you consult an expert for this precise purpose.

In any case, always remember to turn off the electrical current when working, to avoid accidents while installing the hot tub. You must also follow the safety standards exactly; consult these standards in more detail on the page by Hydro-Québec.


Once the hot tub has been delivered, installed on the site and connected, it is time for the start-up. According to the model of hot tub you have selected, the instructions for starting the hot tub may vary; therefore, read the instruction manual carefully before starting.

In general, when starting your hot tub, you will need to follow these steps:

  • Make sure the hot tub filters are not wrapped in plastic protectors, and then fill the hot tub with water.
  • The first water treatment can take between 12 and 24 hours with specified products that you need to purchase (ask the vendor for advice); next, drain the hot tub.
  • Fill the hot tub once more and take a water quality control according to the standards indicated under “Use”.
