Pool resurfacing cost per square foot: what the numbers mean in Phoenix
Pool resurfacing runs roughly $4 to $6 per square foot for plaster and $8 to $12 for a pebble style finish in a 2026 Arizona guide. A national 2026 guide lists replastering at about $5,500 per 1,000 sq ft. Per pool, Arizona plaster runs $6,000 to $10,000. Per square foot rates compare finishes, and per pool totals set a budget. Here are the figures, why the two differ and plain steps to estimate your pool's surface area.

What is the pool resurfacing cost per square foot?
Two 2026 guides give rates per square foot. The Arizona one puts plaster at roughly $4 to $6 and a pebble style finish at $8 to $12, and the national one lists replastering at about $5,500 per 1,000 sq ft, which is $5.50 per square foot.
| Finish | 2026 Arizona pool cost guide | National 2026 cost guide |
|---|---|---|
| Plaster | roughly $4 to $6 per sq ft | about $5,500 per 1,000 sq ft (replastering) |
| Pebble style | $8 to $12 per sq ft | about $6,500 (resurfacing with aggregate) |
National 2026 cost data puts basic resurfacing at around $6.50 per square foot, or roughly $6,500 per 1,000 sq ft for a concrete pool, with repainting at about $1,500 per 1,000 sq ft and tile refinishing at about $30,000. Quartz has no published price in the sources used here, and it is usually described as landing between plaster and pebble style. The Arizona guide does not say whether its rates include labor.
Good to know
Why do per square foot figures and per pool totals differ?
A per square foot rate prices a unit of surface, and a per pool total prices a job. In the same Arizona guide, $4 to $6 per sq ft sits beside $6,000 to $10,000 per pool for a plaster resurface, and the sources do not reconcile the two.
Parts of a job that a rate per square foot does not show:
- Labor. $45 to $65 per hour in national 2026 cost data, on top of the material.
- Drain, clean and refill. An added $425 to $475 before work begins.
- Prep. A full chip-out down to the shell adds cost over light prep.
- Added scope. Waterline tile and coping raise the total.
The figures used here give an hourly labor rate but no hours per pool, so a rate per square foot cannot become a total without a guess.
The national size table shows a second gap: about $320 for a 6 by 8 ft pool up to about $5,200 for a 20 by 40 ft pool. Those figures work out to about $6.50 per square foot of length times width (800 sq ft x $6.50 is $5,200), which sits below the Arizona plaster range of $6,000 to $10,000 per pool.
A pool's finish also covers its walls, not only its floor, so the surface is larger than length times width. Use per square foot rates to compare finishes and per pool ranges to budget.
Good to know
How do you estimate your pool's surface area?
Add the floor outline to the walls, and treat the result as a rough number. These steps work for a rectangular pool:
- Measure the length and width in feet at the water line.
- Multiply length by width for the outline area. For a round pool, multiply radius by radius by 3.14.
- Add the shallow-end and deep-end depths and divide by 2 for an average depth.
- Add length and width, double it, and multiply by the average depth for the wall area.
- Add the outline area and the wall area.
The outline math matches the volume formulas on the formulas page of an LA County Public Health pool study guide (opens in a new tab), which use length x width and radius x radius x 3.14.
| Example pool | Outline | Walls | Rough surface |
|---|---|---|---|
| 12 x 24 ft, 4.5 ft average depth | 288 sq ft | 72 x 4.5 = 324 sq ft | 612 sq ft |
| 14 x 28 ft, 5 ft average depth | 392 sq ft | 84 x 5 = 420 sq ft | 812 sq ft |
| 16 x 32 ft, 5 ft average depth | 512 sq ft | 96 x 5 = 480 sq ft | 992 sq ft |
| 20 x 40 ft, 5.5 ft average depth | 800 sq ft | 120 x 5.5 = 660 sq ft | 1,460 sq ft |
The depths are examples. Steps, benches, curves and a sloped floor change the real number.
Take the 14 by 28 ft pool, about 812 sq ft. At the Arizona guide's $4 to $6 per sq ft for plaster, that is $3,248 to $4,872, set beside $6,000 to $10,000 per pool in the same guide. This is arithmetic on published rates, not a quote.
Costs
Which cost number should you budget with?
Budget with the per pool ranges, then adjust for your own pool. The Phoenix pool resurfacing cost tables carry the full set, and these are the headline ones:
Plaster
$6,000 to $10,000 per pool in Arizona, with a life of 10 to 15 years.
Pebble style
$9,000 to $16,000 per pool in Arizona, with a life of 15 to 25 years.
National average
$11,000, with most homeowners paying $6,000 to $15,000.
Add the $425 to $475 for draining, refilling and cleaning, and any tile or coping. Over 20 years, 2 plaster resurfaces at $6,000 to $10,000 each add up to $12,000 to $20,000, against $9,000 to $16,000 for 1 pebble style job.
The pool cost estimator asks 3 questions about size, finish and condition and returns a low to high range. It is an estimate, not a quote, and the price is set in writing after an in-person look at your pool. Tell us about your pool, and someone from our team will call you back to go over the finish and the budget.

What is the average cost per square foot to resurface a pool in Arizona?
A 2026 Arizona pool cost guide puts plaster at roughly $4 to $6 per square foot and a pebble style finish at $8 to $12. A national 2026 guide lists replastering at about $5,500 per 1,000 sq ft. Quartz has no published per square foot figure.
Is pebble style double the price of plaster per square foot?
In the Arizona guide, pebble style runs $8 to $12 per square foot against $4 to $6 for plaster, about double. It also lasts 15 to 25 years against 10 to 15, and over 20 years that guide says 2 plaster resurfaces usually cost as much as or more than 1 pebble style finish.
Does the price per square foot include draining and refilling?
The sources do not say whether the Arizona rates include it. National 2026 cost data says to budget an added $425 to $475 for draining, refilling and cleaning before work begins, and published ranges list it as an additional cost.
