Estimating the cost to renovate your pool can be complex. This pool resurfacing cost calculator helps you determine the total investment needed based on your pool’s dimensions and preferred finish materials, from standard plaster to premium pebble-tec.
Pool Resurfacing Cost Calculator
Pool Resurfacing Cost Calculator Formula
Surface Area (Rectangular) ≈ (L × W) + [2 × D × (L + W)]

Variables Explained
- Pool Dimensions: The length, width, and average depth determine the total square footage of the interior shell.
- Material Rate: The cost per square foot for the specific finish (Plaster is cheapest, Tile is most expensive).
- Labor & Prep: Includes stripping old finish, acid washing, and bond coating (factored into our average rates).

What is Pool Resurfacing Cost?
Pool resurfacing involves removing the old, worn-out top layer of your pool’s interior and applying a new waterproof finish. This is essential maintenance that prevents leaks, improves aesthetics, and ensures a smooth surface for swimmers.
Most concrete (gunite) pools require resurfacing every 10 to 15 years. Costs fluctuate based on regional labor rates and the choice of premium materials like quartz or pebble, which offer longer lifespans than traditional white plaster.
How to Calculate Pool Resurfacing Cost (Example)
- Measure Dimensions: A 15’x30′ pool with a 5′ average depth.
- Calculate Surface Area: (15×30) + [2×5×(15+30)] = 450 + 450 = 900 sq ft.
- Apply Material Cost: If using Quartz at $9/sq ft, the cost is 900 × $9 = $8,100.
- Add Buffer: Always add 10-15% for unexpected repairs to the shell.
Frequently Asked Questions (FAQ)
Is it cheaper to resurface or replace a pool? Resurfacing is significantly cheaper than a full replacement, costing a fraction of a new installation while extending the life of the structure.
What is the longest-lasting resurfacing material? Pebble-tec and high-quality aggregate finishes can last 20+ years, nearly double the lifespan of basic plaster.
Can I resurface a pool myself? DIY resurfacing is not recommended for gunite pools due to the specialized equipment and chemicals required to ensure a watertight bond.
Does pool resurfacing include tile repair? Usually, waterline tile is priced separately, though many contractors offer a package deal during a full resurface.
