Pool Resurfacing Cost Calculator: Finish & Total Cost
Estimate replaster or refinish cost, split into finish cost and total, from your pool's interior surface area and finish — plaster, quartz, pebble, or tile.
How it works
Resurfacing is priced on the **interior surface** you refinish — the floor plus the walls — not the water volume. The calculator computes that wetted area from your pool's length, width, and average depth: the floor is roughly the plan area, and the walls are the perimeter times the average depth. It then multiplies by a per-square-foot finish rate and adds your extras.
The starting finish rates are typical figures: plaster or marcite around $5 per square foot, quartz aggregate around $6.50, pebble around $10, and full tile far higher. A 32 × 16 ft pool averaging 5 ft deep has about 992 square feet of interior surface, so a replaster lands near $5,000 in material before drain-and-fill, chip-out, and tile-band work.
Use it to compare finishes and sanity-check a quote. Actual jobs add labor for draining, chipping out the old surface, acid washing, and refilling, plus any tile or coping repair — all entered as extras. Finishes and regional labor vary widely, so confirm with local bids.
interior = floor 512 ft² + walls (96 ft perimeter × 5 ft) = 992 ft²
total = 992 × 5 + 1,500 = $6,460
