Pool Replastering Cost
Replastering an average 15 × 30 ft pool costs roughly $8,500–$13,700 including the drain, chip-out, refill and start-up. It is the cheapest way to renew an interior surface and the shortest-lived.
Typical national range

Average 15 × 30 ft pool (about 945 sq ft of interior surface) in standard white plaster, including drain, chip-out, refill and chemical start-up.
What this project needs measured
Measurements are only requested when they change the price of the work you selected. Everything below is collected inside the estimator — you can enter dimensions you already know or measure as you go.
Required
Pool interior surface area
Resurfacing and finish work are priced by the square footage of the interior shell.
Only if it applies
Attached spa
An attached spa is a separate surface and is usually quoted as its own line item.
Only if it applies
Pool perimeter (linear feet)
Tile and coping are priced by the linear foot around the pool edge.
Cost by pool size
| Pool size | Interior surface | Plaster and labour | Total with prep |
|---|---|---|---|
| 10 × 20 ft | ~470 sq ft | $3,100–$4,500 | $5,000–$8,000 |
| 15 × 30 ft | ~945 sq ft | $6,100–$9,000 | $8,500–$13,700 |
| 20 × 40 ft | ~1,460 sq ft | $9,500–$13,900 | $12,700–$20,600 |
| 25 × 45 ft | ~1,895 sq ft | $12,300–$18,000 | $16,100–$26,200 |
Plaster grades
Not all plaster is the same product. The differences are modest in price and meaningful in appearance and durability.
| Type | Rate | Notes |
|---|---|---|
| Standard white marcite | $6.50–$8 / sq ft | The traditional finish. Brightest water, softest surface. |
| Coloured plaster | $7–$9.50 / sq ft | Pigmented; darker colours can fade unevenly with aggressive chemistry. |
| Additive-modified plaster | $8–$9.50 / sq ft | Polymer or pozzolan additives improving durability and stain resistance. |
What makes a quote come in higher
- Multiple existing layers. A pool replastered several times carries more material to chip out and dispose of.
- Structural repair at chip-out. $500–$3,500, and only discoverable once the shell is exposed.
- Tile and coping added. Most homeowners add tile, which is $3,200–$6,400 on an average pool.
- Restricted access. Manual demolition and material handling across the entire job.
- Water delivery. Where hose filling is impractical or restricted.
- Regional labour rates. Up to a 25% swing between the markets PoolSavr models.
Plaster against the alternatives
Over a twenty-year horizon the finishes converge, because plaster requires paying the fixed drain-and-prep cost roughly twice as often.
| Finish | Job cost | Times resurfaced in 20 years | 20-year total |
|---|---|---|---|
| White plaster | $8,500–$13,700 | ~2 | $17,000–$27,400 |
| Quartz aggregate | $10,900–$17,000 | ~1.5 | $16,400–$25,500 |
| Pebble aggregate | $14,000–$22,000 | ~1.2 | $16,800–$26,400 |
How to read a PoolSavr estimate
- Step 1
Instant estimate
Based on your project selections and general pricing assumptions. Useful for deciding whether a project is realistic.
- Step 2
Measured estimate
Uses your pool, spa, or deck dimensions to price the work against the areas actually being resurfaced, tiled, or replaced.
- Step 3
Contractor proposal
Prepared by a licensed professional after inspecting the site. This is the only number that becomes a contract.
PoolSavr is an estimating and matching platform. We do not perform pool work ourselves — licensed local professionals do. Contractors pay PoolSavr for qualified project leads, which is how the estimating tools stay free for homeowners.

Frequently asked questions
- How much does it cost to replaster a pool?
- Roughly $8,500–$13,700 for an average 15 × 30 ft pool, including the drain, chip-out, refill and chemical start-up. Small pools start near $5,000, and large pools run $16,000–$26,000.
- How much is replastering per square foot?
- Standard white plaster runs $6.50–$9.50 per square foot of interior surface installed. Bear in mind that interior surface means floor plus walls, so it is considerably more than the pool footprint — an average 15 × 30 ft pool has around 945 square feet.
- Is replastering cheaper than resurfacing with pebble?
- Upfront, yes — typically 40% less. Over twenty years the two are close to equal, because plaster needs replacing roughly twice as often and each replacement repeats the same fixed drain-and-prep cost.
- How often will I need to do this again?
- Typically every 7–12 years. Water chemistry is the dominant factor: consistently balanced water can push plaster past a decade, while aggressive water can leave a finish rough within five years.
- Can I get a cheaper quote by supplying my own materials?
- Not usually, and it is generally a bad idea. Plaster is mixed on site and applied in a single continuous pour by a specialist crew; contractors buy materials at trade rates and will not warranty work using materials they did not supply.
