Stone for a hot tub pad
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
Remove sod and roots, level the area and slope it slightly for drainage. Install edging so the stone stays inside the footprint.
Ordering and delivery
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
Use a long tape and measure each side twice. If the ground slopes, measure depth at the high and low ends and average them. Irregular outlines can be broken into simple rectangles, triangles and circles; add the pieces for the total square footage before converting to tons.
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.
