Building the hot tub pad base
A filled hot tub can weigh several tons, so the pad must be level and compacted solid. Many manufacturers accept a compacted stone base for some models, while others require concrete; follow your tub’s install guide, since that affects the warranty.

Before the stone goes in
Clear vegetation, rake the soil level and compact it. Lay fabric overlapped at the seams and set edging before spreading the stone.
Buying the stone
If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Crusher run mixes stone and stone dust, so it packs nearly solid when compacted in layers. The scale ticket is the real weight; tons per yard here is a planning figure.
Tools for the job
For anything bigger than a small path, rent a plate compactor; hand tampers cannot match it. A wheelbarrow, shovels, a hard rake and stakes with string are the rest of the kit. Wet the stone lightly before compacting so it binds.
Planning the cost
Quarries and landscape suppliers set their own prices, and they change by region and season. Get the price per ton, the delivery fee and the minimum order. If two products will both work, compare cost per square foot at your depth rather than cost per ton.
