Hot Tub Pad tips
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
Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. Crusher run mixes stone and stone dust, so it packs nearly solid when compacted in layers. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
Measuring the area
Measure length and width in feet at a few points and use the largest figures, since real sites are rarely square. For odd shapes, split the area into rectangles and circles, work out each one and add them together. Depth is the number most people underestimate: drive a stake, run a level string and measure down to the dug-out surface in several spots.
Planning the cost
Stone is usually priced per ton or per cubic yard, and delivery is often a separate charge based on distance. A full truckload can cost less per ton than a partial one, so it can pay to combine projects. Ask whether the quote includes tax, delivery and any small-load fee before you compare yards.
