How Much Does An In-Ground Hot Tub Cost?

The cost of in-ground hot tubs is influenced by several factors. We're sharing a detailed guide on how much an in-ground hot tub costs.

An in-ground hot tub can be a great addition to your outdoor space. Installing an in-ground hot tub on your property can create a luxurious and relaxing environment, and can also increase its value. However, before you hit the market for an in-ground hot tub, you need to be aware of how much it will cost. Here is a detailed guide to in-ground hot tubs and how much you can expect to spend on them.

What Is an In-Ground Hot Tub?

An in-ground hot tub differs from the average hot tub because it's set in the ground. It is often seen as similar to an in-ground pool. They can be surrounded by decks, stone, concrete, or tile.

While a regular hot tub is normally portable, an in-ground hot tub is placed into the ground, and so, is permanent. That is why you should carefully plan before an in-ground hot tub installation.

What Is The Average Cost of An In-Ground Hot Tub?

An in-ground hot tub will generally cost more than an above-ground hot tub because it requires extra installation. The average price of an in-ground hot tub ranges from $7,000 to $20,000. However, installation costs need to be added to this estimate. The installation process also includes preparing the space in the backyard. This can often include excavation or building extra decking.

Factors in Calculating In-Ground Hot Tub Costs

Let's take a look at some of the factors that have to be taken into consideration while calculating in-ground hot tub costs:

Heating Systems

An in-ground hot tub will require a heating system. Most hot tub owners opt for an electrical source near the hot tub placement, but there is also the option of propane or natural gas heat.

Your in-ground hot tub will add to your electric bill whenever it's being used and might cost more in colder months. You can expect to spend $50-$100 on heating charges each month for your in-ground hot tub.


Most above-ground hot tubs do not require any permit for installation. However, since an in-ground is a permanent addition to a property it might require a building permit. Permits differ from state to state.

When you begin planning for your in-ground hot tub installation, make sure to check with your local town hall to inquire whether you'll need a permit. If needed, a permit can be anywhere from $20 to $100.

Concrete Pad

Any hot tub requires strong foundational support. For an in-ground spa, you will require a solid concrete pad before its installation. A concrete slab costs between $4.34 - $7.73 per square foot in North Carolina. Make sure you add these cost estimates to your final cost while planning.


As a hot tub owner, it is your choice what material you choose to set your hot tub in. Will you be building a deck around the hot tub? Would you rather set the hot tub in stone or brick? Is there a specific material you'd like for your patio? Whatever material you choose, your in-ground hot tub cost will vary accordingly.


One of the most important steps for in-ground spa installation is the electrical wiring. A hot tub is not a hot tub without heat. For the heating system to work properly you will require electrical installation.

When you've had your concrete pad built and are now sure where your in-ground hot tub is going to be installed, it's time to have the space wired. Electrical installation for an in-ground hot tub can range from $800 to $1600 in North Carolina.


In-ground hot tub installation can't go right without the expertise of a professional contractor. Some hot tub companies have a team of contractors who they can refer. Otherwise, you will have to find a reputable contractor to make sure the job gets done right.

On-Going Maintenance

It is imperative to understand that an in-ground hot tub is not a one-time cost. As with any other hot tub, you will require ongoing maintenance for as long as you own the hot tub. Monthly maintenance and servicing are essential to keep the hot tub in good condition and ensure it runs smoothly. Maintenance can add $100-$150 to your monthly costs.
