Options for your hot tub base

There are a couple of different options for your hot tub base. 

Hot tubs and swim spas need a solid, level and flat base to allow even distribution of the weight. An uneven weight distribution may cause shell or structural damage. It’s not possible to self-level the hot tub once it’s in place (eg. put planks of wood under the hot tub). So it is essential that the ground is level before hot tub or swim spa delivery and installation.

The base needs to be able to take the weight of the hot tub or swim spa including water and people (especially if it is in any way raised or suspended). This can be upwards of 1 tonne for a standard hot tub model. And much more for a swim spa. Your supplier should be able to give you the full water weight before you prepare the base. 

The bases that will work for a hot tub are:

  1. Concrete slab (ideally between 4-6inches thick).
  2. Existing stones/slabs.
  3. Patio.
  4. Hot tub base/pad.
The hot tub base is a plastic base that jigsaws together to the size required. It creates a base without any construction work, which is good for people who don’t have the time or inclination to build a base. 

What base is unsuitable for a hot tub?

While there are a few different options for a hot tub base. There are some things that will not work. 

Grass is not a suitable base. This is because it will not evenly distribute the weight. And may result in the hot tub or swim spa sitting off level. This will ensure that the water remains in the hot tub (which is useful) and will help keep the hot tub structurally sound. 

 

In conclusion

There are a few options for suitable hot tub base. Any can be used to help extend the lifetime of your hot tub.
