Use caution when installing a hot tub on top of pavers. Hot tubs require a level base that is able to support the weight of the hot tub when it is filled with water and bathers. You can use a concrete slab, gravel, a deck or patio pavers as options to support your hot tub.
What are pavers?
Pavers are used for outdoor flooring and usually are made from brick, clay, concrete, tile or paving stones. They are typically used as decorative walkways, walking paths or driveways and can come in a variety of different patterns, shapes, colours and textures.
Risks associated with placing a hot tub on pavers
One problem people may run into when using pavers is working with an uneven surface. If your hot tub is sitting on a surface that isn’t level, the weight of the hot tub will not be distributed evenly. This can lead to cracks, stretching and structural damage of the hot tub shell.
A second concern is the support that is required for supporting thousands of pounds of water. If the base isn’t strong enough to withstand the weight of a hot tub filled to capacity (water and bathers) it may sink unevenly which will cause damage to the shell of the hot tub.
Options to support the weight of your hot tub
Many hot tub owners elect to pour a concrete base to set up their hot tub. The base needs to be approximately 10 cm-15 cm thick (4”-6” in) and should be wider than the base of the tub. The slab should be pitched for runoff so water doesn’t pool and deteriorate the concrete prematurely.
Although it’s not considered the best looking of all options, gravel can provide an inexpensive but effective way to provide an adequate base for your hot tub.
Your base should be larger than the area of the tub and can be sectioned off with wood or brick to keep the gravel in place.
The gravel should be pressed and levelled off before setting the hot tub on tub of the base.
There are companies that specialize in setting up pavers as a base for your tub. Having a professional handle the base takes care of the major concerns you might encounter when installing the pavers yourself.
Should you decide to do it yourself, you’ll need to research the best material for a hot tub to site on. Having a permeable material is preferred in order for water to pass through allowing you to eliminate the possibility of a drainage issue.
You should also be aware of what is supporting your pavers to ensure that they will stand up to the weight of the hot tub. Consulting with a professional is always advisable before beginning your project. It may save you time and money from mistakes that can be avoided.
With all the talk of water weight, I may surprise you to know that a deck that’s built to code will support even the largest of hot tubs. Decks are built to support 100 lbs. per square foot, which is more than what you will need for a full hot tub.
