The tool
What information does it use?
- Surface area: Interior area (from the plaster tool).
- Current surface: What you're replacing.
- New surface: Plaster, quartz, pebble, etc.
- Region: Regional cost multiplier.

The relationship
The formula in plain English
Cost = surface area × finish cost/sq ft × regional multiplier + prep
White plaster ~$6.50/sq ft, quartz ~$10, pebble ~$13. Add ~$800 drain & acid-wash prep.05
Worked through
A worked example: 900 sq ft pool, pebble finish, southwest
- Base = 900 × $13 = $11,700
- Southwest ×1.05 = $12,285
- + $800 prep = $13,085 total
| Finish | Cost/sq ft | Material+labor | Total +prep | Lifespan |
|---|---|---|---|---|
| White plaster | $6.50 | $5,850 | $6,650 | ~10 yr |
| Quartz | $10 | $9,000 | $9,800 | ~15 yr |
| Pebble | $13 | $11,700 | $12,500 | 20+ yr |

Good inputs
Improve the estimate before relying on it
- Pebble and quartz cost more but last far longer than white plaster.
- Resurfacing includes a drain, acid wash, and refill — budget the prep.
- Aggressive water shortens any finish's life — balance it after refilling.
- Re-tile and new coping are often done at the same time to save on mobilization.
- Get the finish you'll keep for 10+ years, not just the cheapest option.

Common questions
Frequently asked questions
How much does it cost to resurface a pool?
It depends on surface area, finish, and region. White plaster runs about $6.50 per square foot, quartz around $10, and pebble about $13, plus roughly $800 for draining and acid-wash prep. A 900-square-foot pool in quartz lands near $9,800 before regional adjustment.
How long does each pool finish last?
Standard white plaster lasts roughly 10 years, quartz finishes around 15, and pebble finishes 20 years or more. Because resurfacing is disruptive and costly, paying more for a longer-lived finish often works out cheaper per year. Water balance strongly affects how long any finish lasts.
Does resurfacing include draining the pool?
Yes. Resurfacing requires draining the pool, prepping the old surface — typically an acid wash or chip-out — applying the new finish, and refilling. The drain-and-prep step adds several hundred dollars and is included in a proper estimate, along with the refill water cost afterward.
When does a pool need resurfacing?
When the surface becomes rough, stained, hollow-sounding, or starts leaking through cracks and craze lines. Rough plaster also harbors algae and is hard to clean. The interval ranges from about 10 years for white plaster to 20-plus for pebble, depending heavily on how well the water was balanced.
Is pebble worth more than plaster?
For many owners, yes. Pebble costs roughly double white plaster per square foot but lasts about twice as long and resists staining and etching better, so the cost per year can be comparable or better — with a more durable, natural-looking surface. It's a longevity-versus-upfront-cost decision.
How much to replaster a pool?
About $6.50/sq ft for white plaster up to $13 for pebble, plus ~$800 prep; a 900 sq ft pool is roughly $6,650–$12,500.
How often should a pool be resurfaced?
Every ~10 years for plaster, 15 for quartz, 20+ for pebble, depending on water balance.
What is the longest-lasting pool finish?
Pebble finishes last longest — 20 years or more.
