How Much Does It Cost to Redo a Gunite Pool? A Simple Cost Guide

If you’re asking, “How much does it cost to redo a gunite pool?”, your pool may need more than a quick touch-up. Rough plaster, dated tile, cracked decking, old equipment, or a layout that no longer works can all point to a bigger update.
That said, gunite pools are built for long-term use. A strong concrete shell gives homeowners plenty of room to refresh, repair, or redesign without starting from scratch.
A basic pool resurfacing project often costs $6,000 to $15,000. A larger redo with new tile, decking, equipment, covers, a heater, or added features can range from $15,000 to $75,000+. Major structural work or a full backyard renovation can reach $100,000+.
Here’s a clear homeowners' guide to what affects the price and how to plan the project wisely.
Key Takeaways
Redoing a gunite pool can mean anything from resurfacing the interior to updating the deck, equipment, covers, heater, or full pool area.
Most basic resurfacing projects cost $6,000 to $15,000, while larger renovations can reach $15,000 to $75,000+.
The final price depends on pool size, condition, finish materials, access, labor, and how much of the pool you want to update.
What Does It Mean to Redo a Gunite Pool?
Redoing a gunite pool can mean a few different things. It may be as simple as applying new pool plaster or as involved as updating the full pool area.
Common projects include:
Resurfacing the pool interior
Replacing pool tiles
Repairing cracks or worn areas
Updating the pool deck
Adding a pool heater
Installing pool covers
Replacing lights, pumps, or filters
Adding a spa, tanning ledge, water features, or automation
That is why the total cost varies so much. A surface-only job is very different from a full renovation.
Average Cost to Redo a Gunite Pool
The average cost depends on the scope of work. For most homeowners, the cost to resurface a gunite pool falls between $6,000 and $15,000. Broader renovations with tile, coping, decking, or equipment usually cost $15,000 to $75,000+.
A simple cosmetic update, like pool paint or minor tile repair, may cost less. A major redo with structural changes, glass tiles, new decking, and premium equipment can cost significantly more.
Online cost data, pricing data, labor statistics, market studies, and service pros resources can help with early planning, but they cannot price your exact pool. Your final quote depends on pool size, access, condition, materials, and local labor.
Redoing vs. Resurfacing vs. Rebuilding
These terms are often used together, but they are not the same.
Pool resurfacing renews the interior pool surface. This may include plaster, aggregate, pebble, tile, or paint.
A remodel goes further. It may include the surface, tile, coping, equipment, lighting, pool covers, heaters, or the surrounding deck.
A rebuild is the biggest project. It may involve changing the pool shape, depth, plumbing, shell, or full backyard layout.
The right choice depends on what your pool needs. If the shell is sound and the surface is worn, resurfacing may be enough. If the pool is outdated or inefficient, remodeling may make more sense.
What Affects the Cost Most?
Several other factors affect what homeowners pay.
Pool size: Larger pools need more materials, more labor, and more prep. Contractors often price resurfacing by the square foot, including the floor and pool walls.
Pool condition: Surface stains, cracks, hollow spots, leaks, or failing plaster can add repair costs. Minor repairs may be simple, but structural issues can increase costs quickly.
Material choice: Plaster is usually the most cost-effective true resurfacing option. Aggregate finishes, pebble, glass beads, glass tiles, and high-end tiles cost more but may offer better durability or style.
Access: Tight yards, slopes, fencing, or finished landscaping can make the job harder.
Upgrades: A pool heater, automation, lighting, pool covers, or new equipment will raise the overall cost.
Pool Finish Options
Your finish affects the look, feel, lifespan, and upfront cost of the project.
Pool plaster is the classic choice for a concrete pool. It is clean, smooth, and usually the most affordable true new surface.
Aggregate finishes mix plaster with an aggregate material like quartz, stone, pebble, or glass beads. They usually cost more than plaster but offer more texture and durability.
Pebble finishes are a durable option with a natural look. They are popular for custom pools, but the texture is not for everyone.
Pool tiles and glass tiles create a polished, high-end look. They can be used at the waterline, on steps, in a spa, or across the full interior.
Pool paint is often the lowest-cost choice, but it is usually temporary. It can refresh the look, but it will not fix a failing surface.
Pool Deck, Covers, Heaters, and Add-Ons
A gunite pool redo often includes more than the interior finish.
A damaged pool deck can make the whole space feel worn, even if the water looks great. Deck repair, resurfacing, pavers, natural stone, drainage improvements, or expansion can all add to the project.
Pool covers help with safety, debris control, heat retention, and seasonal maintenance. Manual covers are usually less expensive, while automatic covers cost more.
A pool heater can extend the swim season, especially in New England. If equipment work is already part of the project, it may be a practical time to price one.
Popular additional features include LED lighting, bubblers, waterfalls, automation, benches, spas, and tanning ledges. A diving board may also be possible, but depth and safety requirements must be checked first.
Gunite Pools vs. Fiberglass and Vinyl Liner Pools
Redo costs vary by pool types.
A gunite swimming pool has a concrete shell with a separate interior finish. It offers the most design flexibility and can be resurfaced with plaster, aggregate, pebble, tile, and other materials.
Fiberglass pools use a gel coat surface and come in pre-made shapes. They can be lower maintenance but offer less design flexibility.
Vinyl liner pools are usually redone by replacing the liner, not resurfacing plaster. They can cost less upfront, but the finish options are more limited.
For many homeowners, gunite is worth updating because the shell can last for decades with proper care.
Additional Costs to Plan For
Some associated costs are easy to miss. These may include draining, cleaning, refilling, permits, inspections, landscaping repair, electrical work, plumbing, coping, fittings, and startup service.
Hidden damage can also appear after the pool is drained. Cracks, leaks, rust stains, hollow plaster, or exposed steel can change the project scope.
That is why free quotes' normal range numbers are only a starting point. Ask licensed contractors for detailed estimates that separate materials, labor, prep, repairs, deck work, equipment, permits, and cleanup.
How to Keep Costs Under Control
Start by deciding what is necessary now and what can wait. A clear priority list helps you avoid paying for upgrades that do not fit your budget or goals.
Keep the existing shape when possible: Changing the pool depth, layout, or structure can add major cost.
Use premium materials strategically: Glass tile at the waterline, steps, or spa can create a custom look without tiling the entire pool.
Bundle smart upgrades: If the pool is already drained, it may be easier to handle lights, fittings, tile, and minor repairs before the refill.
Choose value over the lowest bid: Spending more money on the right finish or efficient equipment can reduce maintenance headaches later.
Get professional help before work begins: A qualified pool resurfacing pro can help you choose the right scope and avoid paying for the wrong solution.

Frequently Asked Questions
What is the lifespan of a gunite pool?
A well-built gunite pool can last for decades, and the concrete shell can often last 50 years or more with proper care. The interior finish wears faster, so homeowners find resurfacing is usually needed every 7 to 15 years.
Finish choice matters, too. Plaster is often the more affordable option, while pebble, aggregate, and tile cost more per square foot but may last longer.
What are the disadvantages of a gunite pool?
Gunite pools are durable and customizable, but they do come with tradeoffs:
Higher upfront cost
More maintenance than some pool types
Periodic resurfacing costs
Longer construction or renovation timelines
Rough or stained surfaces if the finish wears down
Higher average price for major repairs or custom upgrades
Do gunite pools need to be resurfaced?
Yes. The gunite shell is strong, but the interior finish wears down over time. Plaster, aggregate, pebble, or tile can fade, stain, roughen, or chip.
Can you gunite an existing pool?
Sometimes, but it depends on the existing structure. Adding gunite to an old pool is not a simple resurfacing step.
Converting a fiberglass or vinyl liner pool may require demolition, excavation, plumbing updates, structural work, and a new finish. In many cases, a full rebuild or a different renovation path makes more sense.
