Pool Remodel Cost
A pool remodel runs from about $8,500 for a straight replaster to well over $60,000 for a full renovation with new decking and equipment. Scope drives that spread far more than pool size does.
Typical national range
$14,000–$45,000
Typical full remodel on an average 15 × 30 ft pool: new interior finish, waterline tile, coping and some deck work. Simple replastering starts near $8,500; extensive projects exceed $60,000.
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
Pool perimeter (linear feet)
Tile and coping are priced by the linear foot around the pool edge.
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 deck area
Deck work is priced by square footage, and the condition of the existing slab changes the preparation cost.
Cost by scope
The most useful way to think about a remodel budget is by what is in scope, because that is what actually determines the number. These figures are for an average 15 × 30 ft pool.
| Scope | Typical cost | When it fits |
|---|---|---|
| Replaster only | $8,500–$13,700 | Finish is worn, everything else is sound |
| Pebble resurfacing only | $14,000–$22,000 | As above, but you want a finish that lasts |
| Resurface + waterline tile | $16,900–$27,000 | The most common remodel by a wide margin |
| Resurface + tile + coping | $21,000–$35,000 | Perimeter is failing along with the finish |
| Full remodel with deck | $24,000–$43,000 | Everything visible gets renewed |
| Full remodel + equipment | $30,000–$60,000+ | Pad is aging and the pool is down anyway |
Cost by pool size
Size matters, but less than people expect — because the fixed drain-and-prep cost does not scale, a pool twice the size does not cost twice as much.
| Pool size | Interior surface | Plaster | Pebble |
|---|---|---|---|
| 10 × 20 ft | ~470 sq ft | $5,000–$8,000 | $7,600–$13,000 |
| 15 × 30 ft | ~945 sq ft | $8,500–$13,700 | $14,000–$22,000 |
| 20 × 40 ft | ~1,460 sq ft | $12,700–$20,600 | $21,000–$33,000 |
| 25 × 45 ft | ~1,895 sq ft | $16,100–$26,200 | $27,000–$43,000 |
The decisions that move the number most
- Finish material — up to a 2× swing. White plaster against a polished aggregate is the single largest controllable variable on most projects.
- Whether the deck is in scope — up to $15,000. Deck work is often the largest square-footage item, and resurfacing against replacement is a two-to-three-fold difference.
- Tile and coping — $7,000–$14,000 together. Priced per linear foot, so pool shape matters as much as size.
- Equipment — $2,000–$12,000. A variable-speed pump, a heater and automation add up quickly, but never cheaper than during a remodel.
- Structural condition — $500–$3,500, unknowable in advance. The one line item no online estimate can predict.
- Where you live — up to 25%. San Diego against Phoenix is roughly a third of the difference between plaster and pebble, on labour alone.
What pushes a real proposal above the estimate
When a quote comes back higher than you expected, it is almost always one of these — and the first one on the list accounts for most cases.
- A different scope than you priced. Check this before anything else. Contractors bundle differently, and a proposal including coping and equipment is not comparable to an estimate that did not.
- Structural repair found at chip-out. Cracks, hollow spots and exposed rebar are invisible through water.
- Multiple existing finish layers. More material to remove and dispose of.
- Restricted access. Manual handling instead of machinery, across the whole demolition and material delivery.
- Permits and inspections. Especially where structural or electrical work is involved.
- Deck and drainage problems. Frequently discovered once coping comes off.
Where the money is well spent
Some upgrades pay back and some are purely preference. Worth separating the two before you commit.
A longer-lasting finish
The clearest case. Paying 60% more for a finish that lasts twice as long avoids repeating the entire fixed drain-and-prep cost.
Doing tile during resurfacing
The incremental cost is a fraction of the standalone cost, because the drain and mobilization are already paid for.
A variable-speed pump
Usually the fastest payback on the equipment pad, and in most of the US it is now the only legal replacement anyway.
Fixing drainage while the deck is open
Unglamorous, and the difference between a deck that lasts fifteen years and one that cracks again in three.
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

Frequently asked questions
- How much does it cost to remodel a pool?
- For an average 15 × 30 ft pool, roughly $14,000–$45,000 for a typical remodel including a new interior finish, tile, coping and some deck work. A replaster alone starts near $8,500; a full renovation with new decking and equipment can exceed $60,000.
- What is the cheapest way to update a pool?
- Replastering alone, at roughly $8,500–$13,700 on an average pool. If the finish is genuinely sound, replacing just the waterline tile ($3,200–$6,400) changes the appearance considerably for less.
- Is a pool remodel worth the money?
- As an investment, treat it cautiously — a failing pool is a liability to buyers and a sound one is an amenity, so remodeling protects value more than it creates it. As a use decision it is more straightforward: a rough, stained surface makes a pool unpleasant to swim in, and that is what you are actually buying back.
- Can I finance a pool remodel?
- Commonly, yes. Home equity products, contractor financing and unsecured home-improvement loans are all used. Compare the total interest cost against the difference between finish options — financing a pebble finish over plaster is often a smaller monthly difference than people assume.
- How much does a pool remodel cost per square foot?
- Interior finishes run $6.50–$28 per square foot of shell depending on material, and deck work $6–$26 per square foot. But per-square-foot figures mislead on their own, because tile and coping are priced per linear foot and the drain-and-prep cost is fixed.
