How to build a Hot Tub Base

I think we can all agree that building a perfect garden for the summer must include a Hot Tub?

A lot of owners tend to place their hot tub on their decking, but the water could quickly damage the wood. One of the most important things to think about with placing a hot tub is somewhere where it can have a solid and stable base. Hot tubs are extremely heavy and if it’s simply placed on the ground, it may shift and settle over time. The easiest way to resolve these potential issues is to form a Concrete base.

Learn how to build a hot tub base in these 6 steps…

Step 1: Measurements – To start with, measure the area you’ll need for the hot tub. The best way to do this is to measure the diameter of the hot tub and add several feet around it. For example, if your tub is 5 feet across, you may want to plan on a base that’s 7 by 7 feet. This isn’t a fixed rule, so you can certainly go larger if you want some extra space around the hot tub.

Step 2: Location – Next, decide where you want the hot tub base to be placed in your garden. You want the location to be relatively level, and the tub base swill need to be relatively close to water and power connections. When you’ve finally decided, measure out the area and mark it with string or marking paint.

Step 3: Digging – Dig out the area where the base will be to a depth of 18 inches. If the area is extremely large, you may want to consider renting a small backhoe. Otherwise, some shovels and willing hands is all you’ll need. Don’t forget to order a Skip ready for this part!

Step 4: Gravel – Fill the first 12 inches of the excavation with medium-grade gravel. Then top that off with 4 inches of sand. Level the top of the sand so you have a flat surface. A good way to do this is to lay a long board across sections of the sand and lay your level on top of that. You can also support a taut string 1 inch above the surface and check that with a level as well. Tamp down the sand so the surface is firm.

Step 5: Perimeter – Edge the perimeter of the base with pavers. By doing the perimeter first with a consistent size of pavers, you’ll give the base a finished look. Check to make sure that they’re level as you install them.

Step 6: Pavers – Fill the interior of the base with pavers. Some pavers come in different sizes, so you can vary the look by including multiple different sizes. If the pavers are of the same shape, you can change the direction to give your base an interesting and unique dimension. Check out our paving range to get some inspiration.
