How to install a hot tub base using pea gravel

Updated February 21, 2017

Using pea gravel as a base for your hot tub has some distinct advantages. From an aesthetic standpoint, gravel can complement a variety of types of landscaping. From a practical standpoint, a pea gravel base offers the advantage of easy drainage, unlike a solid brick, concrete or wood base. A secure and lasting pea gravel base can be made with simple tools and materials.

Measure the dimensions of the base of the hot tub. You want a base that's about 60 cm (2 feet) wider than the dimensions of the tub to allow for spilling and splashing.

Mark the area on your lawn where you will be installing the tub with a can of marking paint.

Dig out the area you've marked to a depth of `15 cm (6 inches) with a shovel. Remove the excess dirt with a wheelbarrow.

Line the bottom of the excavated area with landscape cloth, cutting it to size with scissors. If you need more than one piece of cloth, overlap the edges of the pieces by 7.5 to 10 cm (3 to 4 inches).

Place 10 cm (4 inches) of medium-grade construction gravel on top of the landscape cloth, and rake it so that the top is relatively smooth and level.

Add pea gravel on top of the medium-grade gravel to match the top of the excavated area. Smooth the gravel with a rake and make sure that it's level with the surrounding ground.
