Hot Tub Foundations: Concrete Alternatives

In part one of this two-part blog series, we looked at some of the basic factors to be considering when choosing a hot tub foundation, plus why concrete is the most common material utilized for this need. A foundation helps with everything from hot tub convenience to efficiency, longevity and more, and choosing the right material and other variables will be important here.

At Packman’s Pools, we’re here to offer a wide range of swimming pool and hot tub products and services for clients around Salt Lake City and other parts of Utah, including fiberglass hot tubs, gunite options and more. While part one of our series went over some basics and the advantages of concrete as a foundation material, today’s part two will look into certain concrete alternatives that may also be ideal for your hot tub foundation.

Wood Deck

Likely the most common concrete alternative regularly used for hot tub foundations is the wooden deck, which can provide a rustic aesthetic that many homeowners love. Wooden decks are also highly versatile in terms of being able to match various backyard themes – and if you’re considering adding a gazebo or other structures around your hot tub area, this may be an ideal choice.

If you decide to go with a deck, be sure to choose a high-quality, durable wood that can withstand harsh weather conditions. You may also want to consider adding a sealant or other protective coating to ensure the wood stays in good condition for years to come.

Paving Stones

Another popular choice for hot tub foundations is paving stones, which can offer both durability and visual appeal. Paving stones are available in a variety of colors, shapes and sizes, allowing you to create a unique design for your hot tub area. Plus, they are relatively easy to install and can be replaced individually if needed.

However, it’s important to note that while paving stones may seem like an affordable option at first glance, the cost can add up quickly depending on the size of your hot tub and the area you need to cover.


For a low-cost option that still offers decent drainage, consider using gravel as your hot tub foundation. It’s relatively simple and inexpensive to install, plus it can easily be replaced if needed. However, gravel may not be the most comfortable surface for bare feet, so keep this in mind when making your decision.

Non-Recommended Materials

On the flip side, there are also certain materials that we do not recommend using for hot tub foundations. These include dirt, sand, and grass – while they may be cheap or readily available, they offer poor drainage and can easily shift over time, causing unevenness and potential damage to your hot tub.
