Pool Resurfacing Cost Calculator
Estimate the cost to resurface an in-ground pool's interior from its surface area and your material and labor rates per square foot.
How this calculator works
Resurfacing cost scales with how much interior surface the pool has and the rates your material and labor charge per square foot. This calculator finds your pool’s surface area from its length and width, then applies your material rate and labor rate to that area and adds the two together.
Formula: Total cost = pool surface area (length × width) × material rate per sq ft + same area × labor rate per sq ft.
Worked example
A 30 ft × 15 ft pool, $5/sq ft material, $6/sq ft labor:
- Surface area: 30 × 15 = 450 sq ft
- Material: 450 × $5 = $2,250
- Labor: 450 × $6 = $2,700
- Total cost: $4,950
Notes
Plaster resurfacing is the cheapest common option. Pebble or quartz aggregate finishes cost more per square foot but last longer and resist staining better, so they can be worth the higher rate if you plan to keep the pool for many years.
A pool typically needs resurfacing every 10-20 years, depending on the original finish and how well the water chemistry has been maintained. Poor chemistry maintenance can wear a surface out sooner than its typical lifespan.
How to use
Enter your pool’s length and width to get its surface area, then set a material rate and a labor rate per square foot that match the finish you’re considering, such as plaster or pebble aggregate. Get contractor quotes for your specific finish and region to refine the estimate.
Pool chemistry estimates only. Always test your water and follow your specific product’s label — actual dose depends on the product’s exact strength and your test results.
Frequently asked questions
How much does it cost to resurface a pool?
It depends on your pool's surface area and the material and labor rates for the finish you choose. This calculator multiplies your pool's length by width to get surface area, then applies your material rate and labor rate per square foot and adds the two together for a total estimate.
What's the cheapest pool resurfacing option?
Plaster is the cheapest common resurfacing option. Pebble or quartz aggregate finishes cost more per square foot up front, but they last longer and resist staining better, which can make them a better value depending on how long you plan to keep the pool.
How often does a pool need to be resurfaced?
A pool typically needs resurfacing every 10 to 20 years, depending on the original finish and how well the water chemistry has been maintained over that time. Plaster tends to wear sooner than pebble or quartz aggregate finishes.
Does this resurfacing estimate include anything besides the pool interior?
No, this estimate covers just the material and labor to resurface the pool's interior surface area. It doesn't include tile work, coping repair, drainage, or other related projects that sometimes get done at the same time as resurfacing.
