How Much Does It Cost to Install a Hot Tub?

During your search for a new hot tub to add to your backyard, one of the first questions to pop up will be, “How much does it cost to install a hot tub?” This is a great question to ask. It’s important to be prepared to budget the cost of hot tub installation. And while some installations are pricier than others, there are certainly ways that you can save money and still have a great hot tub.

Here are some costs to consider when planning your hot tub installation.

Type of hot tub

The first cost to consider is the type of hot tub you’d like to have installed.

HomeAdvisor.com reports that “The national cost to install an above-ground hot tub average is $315, with most homeowners spending between $157 and $490. The approximate cost to install a built-in hot tub varies from $15,000 to $20,000.”

If you are on a budget, installing an above-ground hot tub, like a Hot Spring or Freeflow hot tub, you’ll save a considerable amount of money. If you already have a cement patio or sturdy deck, you can save even more money with your hot tub installation!


One of the biggest factors in hot tub installation is the foundation. It is incredibly important that your new hot tub is installed on a level, sturdy foundation that can easily bear the weight of the tub.

Here are some hot tub foundation ideas:

  • Prefabricated Spa Pad – $100-$200. Combines strength with convenience, saving you time and money. They are easy to assemble and there is no need for a large amount of prep-time before installation.
  • Gravel Base – $100-$250. Also one of the more affordable options. It costs about the same as a prefabricated spa pad, but it requires more time and effort. If your yard is not level, however, it may be worth the time and expense of leveling out the spot, rather than just laying a spa pad down on uneven ground.
  • Concrete Slab – $2,500. While it’s a little more expensive, a concrete slab is a much more stable foundation for your hot tub, compared to a spa pad or gravel base. If you don’t already have a concrete patio, the best slab to build is at least 4-inches thick. Make sure you allow plenty of time for it to dry and cure.
  • Deck – $4,000 to $10,000, including a building permit (check your local building department to confirm cost). Unless you already have a durable deck previously built, this is definitely the most expensive foundation to build for your hot tub. However, it can be a great long-term investment for your home.

Electricity and Plumbing

If your home isn’t already set up with the proper connections, you’re going to have to factor in the cost of plumbing and electricity to your hot tub. Although our Freeflow plug-n-play hot tubs only need a standard 110v outlet for power, they heat up faster if plugged into a 220v system. If you want to upgrade, you will need an electrician to install the electrical and GFCI breaker.

While costs vary from plumber to plumber and electrician to electrician, you can expect to pay at least $600 to $5,000 in plumbing and $200 or more for electricity. Contact a few of your local plumbers and electricians to get some quotes and compare.


For delivery and transportation of your new hot tub, it may cost around $100 to $300. If you would like to know how much it will cost for SpaExpo to transport and deliver, feel free to ask us!


Landscaping after your new hot tub is installed can truly finish your backyard’s transformation into a luxury retreat. Between landscaping supplies and plants, it may cost $500-$750.

While the installation cost can add up pretty quickly, spending every evening soaking in your hot tub is priceless. And with SpaExpo, you get the very best products for the very best prices. Contact SpaExpo in Austin today to schedule a test soak!
