What Is The Best Slab For a Hot Tub?
A new hot tub is a great way to unwind and relax after a long day. But having a suitable slab is essential for ensuring your hot tub is safe and secure. There are various materials that can be used as a hot tub foundation surface, and each has its pros and cons. In this article, we’ll discuss the different types of hot tub foundations, the pros and cons of each, and the best base for a spa pad and hot tub.
If you are looking for the best base for a hot tub, there are several factors to consider, such as budget, location, and personal preference. Concrete, gravel, pavers, and synthetic hot tub foundation pads are all viable deck options.
A concrete base is one of the most popular choices, as it is strong, durable, and low maintenance. The base should be at least four inches thick to ensure maximum strength, although six inches is recommended. However, concrete is permanent and cannot be moved.
A gravel base is also a good option as it is cost-effective, easy to install, and great for drainage. However, make sure to use 3/4 inch crushed stone for gravel, not pea gravel or river stone, as actual gravel is more suitable for a hot tub foundation base.
Pavers can add a decorative touch to your hot tub deck area. However, this option requires more work during installation, requiring six inches of gravel, one inch of sand, and the pavers.
Finally, synthetic hot tub pads are easier to install than a concrete base and can be formed over bare dirt. They are also lightweight and portable, making them ideal for those who want to relocate their hot tub. However, they are less durable than the other options.
The Best Hot Tub Foundation: Is Concrete For Your Swim Spa Deck
Here is the proper steps to install a concrete hot tub pad and swim spa base:
- Dig out the area for 4-inches of crushed stone gravel hot tub base and 6 inches for concrete.
- Install 4 inches of 3/4 inch crushed stone and compact it thoroughly.
- Place your forms leveled using 2×6’s with no pitch and two half inch course screws to drill together for support.
- Install #5 rebar one foot on center in horizontal and vertical directions.
- Use a 5000 psi concrete mix and pour it 6 inches thick.
- Finish the surface with a rough texture broom finish
- Use a cure-n-seal concrete sealer and wait 28 days for the concrete to fully cure before placing hot tub on it.
Cost Of Using Concrete & Gravel & Pavers As a Hot Tub Base
Using concrete as a foundation for a spa is a viable option that can cost between $400 and $500 for an 8’x8′ spa base, or approximately $5 to $10 per square foot. However, there are other options available that may be more cost effective, such as gravel, which can cost between $250 and $450 for an 8’x8′ spa base, or patio pavers at $8 to $24 per sq. ft. with an average of $16 per square foot, which would be $1,024 for 8×8. Pavers require more work to install. Ultimately, the cost of using concrete as a support system for a spa will depend on the size of the hot tub spa and the area of the concrete foundation needed.
