What Is The Best Base for a Hot Tub?

When you decide to buy or install a new hot tub, make sure that the site is prepared. This will help ensure that the tub will sit nicely.

A solid base is important to support the weight of a hot tub. In this guide, we will talk about the various considerations involved in making a hot tub base that's right for your home.


Hot Tub Base Options

Concrete Base

This is a common approach for hot tubs because it provides strong support and is easy to lay. Also, it keeps the area clean and looks good. If the concrete look is not an issue, then make the pad slightly bigger than the hot tub's footprint to hide the 'concrete look'. You can also trim the bottom of the pad to prevent the look of concrete.

The concrete pad should be at least 10 cm thick. We also recommend the pad to be sloped at 1.5cm for 3.5m to prevent pooling.


Patio, Block Paving and Other Existing Stone Surface

Most patio and block paving materials can withstand the weight of a hot tub. However, they may require some specialist advice to ensure their longevity.

Although it is economical to use an existing area, there are some factors to consider before going ahead with any work. One of these is ensuring that the drainage is adequate.



One of the main reasons why people love using decking is that it looks great and is very comfortable when wet. Another reason why people love using it is that it is very durable and can last a long time.

A lot of people don't realize that decks attached to their homes can increase the vibration from the spa pump. Fortunately, there are various solutions that can help reduce this issue.

If you are planning on installing a hot tub on a deck, then you will need to consider the strength of the supports underneath.


Other Bases

Some surfaces are better than others and some are not suitable for hot tubs.

Some of the factors that you should consider when choosing a surface are as follows: 1) The drainage is good 2) The surface is flat 3) It should take the weight of a full hot tub away from it 4) It should be absolutely fine.
