How is Pool Resurfacing Cost Calculated?
Pool resurfacing is priced per square foot of interior surface. The finish sets the base rate — from ~$4/sq ft for white plaster to ~$10/sq ft for a glass-bead finish — plus surface prep (crack repair or a full chip-out) and add-ons like new tile, coping, and draining the pool. A typical 600-800 sq ft pool runs $4,000-$9,000 depending on finish and scope.

Key Factors Influencing Pool Resurfacing Cost
Finish & Surface Area
The finish is the biggest cost and durability factor. White and colored plaster are the affordable, traditional choices but have the shortest lifespan. Quartz aggregate adds durability and stain resistance. Pebble finishes are the popular premium option — natural-looking and long-lasting. Glass-bead finishes are the top tier. Cost scales directly with the pool's interior surface area (floor + walls), so larger pools cost proportionally more.
Prep & Add-Ons
- Surface Prep: Minor crack/hollow-spot repair or a full chip-out to the bare shell adds $1.50-$2.50/sq ft and drives long-term durability.
- Tile & Coping: Replacing waterline tile and coping during resurfacing avoids a second mobilization and refreshes the pool's most visible areas.
- Draining & Refill: The pool must be fully drained and carefully refilled and balanced for the new finish to cure.
Average Pool Resurfacing Cost by Finish
| Finish | Installed / Sq Ft | 700 Sq Ft Pool | Lifespan |
|---|---|---|---|
| White Plaster | $4 - $5.50 | $2,800 - $3,850 | 7-12 years |
| Colored Plaster | $5 - $6.50 | $3,500 - $4,550 | 7-12 years |
| Quartz Aggregate | $6 - $8 | $4,200 - $5,600 | 10-15 years |
| Pebble Aggregate | $8 - $11 | $5,600 - $7,700 | 15-20+ years |
| Glass Bead | $10 - $14 | $7,000 - $9,800 | 20+ years |
Common Add-Ons
| Add-On | Cost | Notes |
|---|---|---|
| Full Chip-Out | $2.50/sq ft | Remove old layers to bare shell for best bond. |
| Waterline Tile | $3/sq ft | New tile band at the waterline. |
| Coping Replacement | ~$2,000 | Replace the edge stones around the pool. |
| Drain & Refill | ~$350 | Drain old water and refill for curing. |

How to Estimate Pool Resurfacing Cost Manually
Pool resurfacing (re-plastering) is priced per square foot of interior surface. The finish sets the base rate, then the pool type and surface prep adjust it. Here's how to estimate it.
Step 1: Measure Interior Surface Area
This is the floor and walls that receive the finish, not the water surface. A typical residential pool has 500-900 sq ft of interior surface. A rough estimate for a rectangular pool: (length × width) + (perimeter × average depth).
Step 2: Pick the Finish
Installed rates per sq ft by finish:
- White Plaster: ~$4/sq ft — standard, 7-12 year life
- Colored Plaster: ~$5/sq ft — tinted finish
- Quartz Aggregate: ~$6.50/sq ft — more durable, 10-15 years
- Pebble Aggregate: ~$8.50/sq ft — premium, 15-20+ years
- Glass Bead: ~$10/sq ft — top-tier finish and look
Step 3: Add Pool Type & Prep
Gunite/concrete is the standard re-plaster substrate; fiberglass and vinyl pools adjust the rate slightly. Then add prep: minor crack and hollow-spot repair (~$1.50/sq ft) or a full chip-out to the bare shell (~$2.50/sq ft). Draining/refilling, new waterline tile, and coping are common add-ons.
Step 4: Apply the Formula
(Surface Sq Ft × Finish Rate × Type Factor) + Prep + Add-ons = Total
Example: 800 sq ft gunite pool, pebble finish ($8.50/sq ft), full chip-out (+$2.50/sq ft), drain & refill (+$350): 800 × $8.50 + 800 × $2.50 + $350 = $6,800 + $2,000 + $350 = $9,150.
Frequently Asked Questions
In 2026, pool resurfacing typically costs $4-$10 per square foot of interior surface, so a standard 600-800 sq ft in-ground pool runs about $4,000-$9,000 with a plaster or quartz finish. A basic white-plaster re-do on a smaller pool can be $3,500-$5,500, while a premium pebble or glass-bead finish on a large pool with a full chip-out and new tile can exceed $12,000. The biggest cost drivers are the pool's surface area, the finish you choose, how much old material must be chipped out, and add-ons like new waterline tile, coping, and draining/refilling the water.
It depends on the finish. Standard white plaster (marcite) lasts about 7-12 years before it stains, etches, or gets rough and needs resurfacing. Quartz aggregate finishes last about 10-15 years, and pebble finishes (PebbleTec-style) can last 15-20+ years with good water chemistry. Fiberglass gelcoat surfaces last 10-15 years before refinishing. Signs you're due include rough or chalky surfaces, persistent staining, plaster flaking or 'spalling,' visible cracks, exposed gunite, and rising chemical/water loss. Good water balance and maintenance significantly extend the life of any finish.
It's a trade-off between cost, appearance, and longevity. Plaster (white or colored) is the most affordable and traditional, but has the shortest lifespan and is most prone to staining and etching. Quartz finishes blend plaster with quartz aggregate for better durability, color, and stain resistance at a moderate price. Pebble finishes (exposed natural pebbles) are the most popular premium choice — extremely durable, natural-looking, and long-lasting (15-20+ years). Glass-bead finishes are top-tier for appearance and smoothness but cost the most. For most owners, quartz or pebble offers the best long-term value despite the higher upfront cost.
The terms overlap. 'Replastering' specifically means applying a new plaster (or aggregate) coat over the pool's interior, and is the most common form of resurfacing for gunite/concrete pools. 'Resurfacing' is the broader term for renewing any pool's interior surface — which for a fiberglass pool means refinishing the gelcoat, and for a vinyl-liner pool means replacing the liner. In all cases the goal is the same: restore a smooth, watertight, attractive interior. This calculator covers re-plastering/aggregate finishes for gunite pools and refinishing for fiberglass and vinyl-liner pools.
Not always. If the existing surface is sound and only one or two coats deep, a contractor can sometimes bond a new finish over a properly prepped surface. However, a full chip-out — removing the old plaster down to the gunite shell — is recommended (and often necessary) when the pool has multiple old layers, delamination, hollow spots, or extensive damage, because new finish won't bond reliably over failing material. A chip-out adds labor and disposal cost (~$2.50/sq ft here) but produces the most durable, longest-lasting result and is standard for older pools with several previous re-plasters.
A typical pool resurfacing project takes about 5-10 days from start to refill. The process includes draining the pool, chipping out or prepping the old surface, repairing cracks and hollow spots, replacing tile or coping if included, applying the new finish (plaster, quartz, or pebble), and then a careful refill and start-up. The new finish then needs a 'curing' and brushing/water-balancing process over the following weeks. Weather, pool size, the finish type, and the amount of repair and tile work all affect the timeline. The pool is unusable while drained and curing.
Often yes — it's the most cost-effective time to do it. The pool is already drained and crews are on-site, so adding new waterline tile and coping avoids paying for a second mobilization and drain/refill later. The waterline tile and coping are also the most visible parts of the pool, so refreshing them along with the interior finish gives a complete, cohesive renovation. If your existing tile and coping are still in good condition and match your taste, you can keep them; but cracked, dated, or loose tile and coping are best addressed during resurfacing rather than as a separate project.
Resurfacing requires a completely dry, clean shell so the new plaster or finish can bond and cure properly, so the pool must be fully drained. Draining an in-ground pool should be done carefully — and sometimes with a hydrostatic relief valve opened — because an empty pool can 'float' or crack if groundwater pressure is high, especially after heavy rain or in high water-table areas. That's why draining and refilling is treated as a distinct service. A professional manages the drain, protects the empty shell, and handles a proper refill and chemical start-up to cure the new finish correctly.
