What replastering YOUR pool really costs — plaster, quartz & pebble price range by size.
Pool dimensions
All in feet. Interior surface area = floor + all walls, using the average of the two depths for the long walls. For a flat-bottom pool, set both depths equal. Non-rectangular pools have less surface than their bounding box, so a shape factor trims the estimate.
Finish & condition
Finish is the dominant cost driver per sq ft. Condition sets the prep labor: Good = clean, no cracks, minimal staining; Fair = hairline cracks or light staining, surface still intact; Poor = major cracks, hollow/delaminating areas, or rebar showing — adds chip-out and crack-repair labor.
Add-ons & region
Priced per linear foot of perimeter (~$30/ft installed). Most replaster jobs replace the tile band at the same time.
National baseline = 1.00. High-cost coastal CA / Northeast ~1.20–1.35; lower-cost areas ~0.85–0.95. Clamped to 0.85–1.35.
This estimator gives you a realistic cost range to resurface (replaster) an in-ground pool before you call contractors — so you can budget honestly and tell whether a bid is fair. It first computes your pool's interior surface area (floor plus all four walls) from your dimensions, applies a shape factor for non-rectangular pools, then prices the chosen finish (white plaster, quartz, or pebble) per square foot, scaled by surface condition. It adds a flat drain / acid-wash / refill allowance, an optional waterline tile add-on, and a regional cost index. The output is always a low–high range — never a single firm number — because real bids vary with access, repairs, and local labor. Everything is calculated privately in your browser, free.
A 16 x 32 ft rectangular pool, 3.5 ft shallow and 8 ft deep, quartz finish, fair condition, no tile, national region (1.00):
So you'd budget roughly $8,700–$12,300 for this pool — then get 3 written, itemized bids to confirm.
avg_depth = (shallow + deep) / 2
floor = length × width
long_walls = length × avg_depth × 2
end_walls = width × shallow + width × deep
rect_area = floor + long_walls + end_walls
shape = rect 1.00 | oval 0.90 | freeform 0.85
area = round(rect_area × shape)
finish $/sqft = plaster 6.50 | quartz 8.50 | pebble 11.00
prep = good 1.00 | fair 1.08 | poor 1.20
finish_sub = area × finish_rate × prep
drain/refill= $450 (flat)
tile = include ? round(perimeter × shape) × $30 : 0
subtotal = finish_sub + 450 + tile
total = round(subtotal × region_index) region clamped 0.85..1.35
range = low = round(total × 0.85) ... high = round(total × 1.20)
$/sqft = round(total / area, 2) (only if area > 0)
Finish $/sq ft are 2025 US national mid-ranges (white plaster ~$4–8, quartz ~$7–10, pebble ~$8–15); the tool uses representative midpoints and applies a −15% / +20% band — the band, not the point estimate, is the deliverable. The drain/acid-wash/refill flat $450 is sized for a typical 15k–25k-gallon pool.

The default height=1240 fits a typical pool. For very large pools or all options enabled, bump it to ~1400–1600 so nothing scrolls inside the frame.

Most residential jobs run ~$6,500–$15,000 (national average ~$11,000). Price tracks interior surface area (sq ft of plaster, not gallons) and finish: white plaster ~$6.50/sq ft, quartz ~$8.50/sq ft, pebble ~$11/sq ft. A 16x32 pool has ~1,088 sq ft of surface. This is a planning estimate, not a quote.
It's priced on SURFACE area (floor + all walls), not gallons. Use (L×W) for the floor, plus (L×avg depth×2) for the long walls, plus (W×shallow) + (W×deep) for the end walls. A 16x32 pool, 3.5 ft to 8 ft deep, is about 1,088 sq ft. This tool runs that formula for you.
White plaster (~$6.50/sq ft) is cheapest but shortest-lived (7–12 yrs). Quartz (~$8.50/sq ft) adds durability and stain resistance (10–15 yrs). Pebble (~$11/sq ft) is toughest and longest-lasting (15–20+ yrs) — priciest upfront but often cheapest per year. The tool shows a cost-per-year figure to compare.
Real bids swing with access, equipment, structural/crack repair, plumbing and light work, and local labor. Finish alone can swing the total 60–70%. A range is honest; budget toward the midpoint-to-high end and get 3 itemized bids.
Yes for a flat $450 drain / acid-wash / clean / refill allowance (typical 15k–25k-gal pool). Waterline tile is an optional add-on (~$30/linear ft). It does NOT include coping, decking, new equipment, structural repairs, or plumbing changes.
