How much sand do I need for a 15 ft above-ground pool?

Short answer

A 15 ft round above-ground pool needs about 1.09 cubic yards of mason sand for a 2-inch bed, roughly 1.47 tons, or 59 bags of 50 lb, before any sand cove (which some makers forbid).

How to work it out

  1. Area: 3.1416 × (15 ft ÷ 2)² = 177 sq ft
  2. Bed: 176.7 sq ft × 2 in ÷ 12 = 29.5 cu ft
  3. Total: 29.5 cu ft ÷ 27 = 1.09 cu yd × 100 lb per cu ft = 2,945 lb = 1.47 tons
  4. Bags: 2,945 lb ÷ 50 lb = 59 bags

A 15 ft round pool has a base of about 177 sq ft, and its sand is a job most people do with bags: under two tons, delivered on a pallet or picked up over a couple of trips.

  • Use mason (masonry) sand: Swimline’s instructions say not to use beach or play sand. Rake it level and tamp it before the liner goes in.
Follow your pool’s manualPool makers disagree on the base. Most call for a 2 in sand bed inside the bottom track, with the track itself on solid, level ground, not sand. Some want a sand cove; Doughboy forbids sand in the cove. Your pool’s installation manual wins over this page.

Pre-formed foam pool coveWith no sand cove, a pre-formed foam cove fills the corner between floor and wall so the liner can’t slip under the wall.

Sand for a small round pool

On a 15 ft pool the cove is a bigger share of the sand than on larger pools, because the wall is long relative to the floor: a sand cove would add about 6 cubic feet to the bed’s 29. That makes the cove decision matter more. If your pool’s manual asks for a foam cove or packed earth instead of sand, the count drops to about 59 bags.

  • Bed: about 29 cubic feet at 2 in, raked level inside the bottom track.
  • Clear a margin: Swimline’s instructions say to clear grass and roots for 1 ft beyond the pool, so plan the cleared circle at about 17 ft.
  • Frame and easy-set pools. Many 15 ft pools are one of these, and their manuals give their own base instructions; read yours first and buy sand only if it asks for it.
  • Spare bags: a couple of extra bags covers spills and lets you top up low spots after you tamp.
