hot tub installation price

Installing a hot tub may be more complex than you imagine. Find out exactly what to expect.

Although there are a number of videos online covering DIY hot tub installation, industry experts and manufacturers recommend that you don’t go it alone. The primary reason is because hot tub installation can pose a potential danger when lifting heavy equipment and dealing with electrical configurations.

Unless you have such experience or the help of a friend that happens to be an electrician, it’s best to pay for installation upon purchase or hire a contractor to do the job for you.

What does basic hot tub installation entail?

Standard hot tub installation requires:

  • Electrical circuit
  • Gas line
  • Hot tub pad

In order for a hot tub to sit on a solid foundation, it must be assembled on a concrete pad with a supporting hot tub pad layered on top. This type of foundation is critical because uneven settling under a hot tub can cause leakage and damage to the spa over time.

Depending on the model, a hot tub will also require connection to a 20 amp/240 V circuit with a green insulated ground wire and white neutral wire to meet code requirements. National electric codes dictate that hot tub wiring is encased in a metal conduit with a disconnection switch a visible distance from the hot tub pump.

A hot tub will connect to a gas line with a 100 K BTU heater; if a larger heater is used to heat a bigger spa, a larger gas line will be required. A gas line always calls for professional sizing and installation.

What makes up hot tub installation cost?

Clearly, hot tub installation is an expert task that shouldn’t be left in the hands of amateurs for safety purposes.
