How Much Does a Gunite Pool Cost to Build and Own?

Look Closely at What a Base Pool Package Actually Covers

A starting quote from a pool builder rarely covers a swim-ready backyard. Gunite is a mixture of cement, sand, and water sprayed at high speed through a hose over a woven steel frame. Because builders sculpt this wet concrete directly in your yard, they can build nearly any shape or depth you want. That design freedom also means baseline quotes often outline only the bare structural shell and the most basic mechanical equipment.

A standard builder package usually includes digging the hole, tying the steel rebar cage, spraying the gunite shell, and laying the plumbing lines underneath the structure. The quote also typically provides a basic circulation pump, a standard filter, and standard white plaster (the smooth waterproof coating applied over the concrete). Most base contracts include standard coping (the stone or cap edge along the pool rim) made from poured concrete or precast stones.

What gets left out often catches buyers off guard. Standard bids almost never include decking (the paved walkway around the water). Without decking added to your contract, your pool will be surrounded by bare mud and dirt trenches when the water fills. Basic quotes also leave out the electrical hookups that connect the equipment pad to your home electrical panel, requiring you to hire an independent electrician.

Pool dimensions and depth also change the starting price. A simple rectangular basin measuring twelve by twenty-four feet requires far less concrete, steel, and labor than a large custom freeform pool. Every foot of depth or width adds more soil that workers must excavate and haul away, and more surface area that requires interior plaster.

Anticipate Site Surprises Before the Excavators Dig Up Your Lawn

A contractor prices your project based on what they can see above ground. Once heavy excavation machinery starts digging, unexpected yard conditions can quickly increase your final bill. Review this checklist of common site barriers before you sign an excavation contract:

• Rocky soil or buried bedrock: Standard digging assumes soft soil. If the backhoe hits solid rock, hard shale, or large boulders, the crew must bring in hydraulic jackhammers. You will pay separate hourly equipment fees for this difficult work.
• High underground water tables: If groundwater pools in the excavated basin, water pressure can collapse dirt walls before crews spray the concrete. Builders must install dewatering pumps and gravel drainage beds to keep the hole dry during construction.
• Yard access barriers: Heavy machinery needs a wide path into your backyard. If your side yard is narrow, you may need to pay to take down and rebuild fences, move air conditioning units, or lay heavy ground mats to protect your driveway from cracking.
• Dirt removal and disposal fees: Digging out a pool basin displaces tons of dirt. If you cannot use that soil to level other areas of your yard, you must pay dump truck fees to haul it away.
• Permits and engineering plans: Local building departments require structural engineering stamps and safety permits before construction begins. These fees depend on your municipality and rarely appear in a builder's base pool price.
• Mandatory safety fences: Building codes require a four-foot or five-foot safety fence with self-closing and self-latching gates around the water. Adding this fence is an out-of-pocket expense that pool builders rarely include in their pool package.

Weigh Your Interior Finishes and Extra Features Carefully

The interior finish you pick determines how your pool looks, how rough it feels under your feet, and how often you will need to refinish the surface. Standard white plaster remains the most affordable option. It provides a bright, classic blue tint and feels smooth to the touch, but it stains easily and wears down in five to ten years if water chemistry fluctuates.

Pebble surfaces blend small river pebbles or glass beads into colored plaster. A pebble surface costs significantly more upfront than basic plaster, but it resists chemical damage far better and often lasts fifteen to twenty years before needing replacement. For an upscale look, glass waterline tile (the band of tile installed along the top edge of the pool where the water surface sits) adds color and resists mineral scale, though tiling an entire pool interior demands extensive manual labor that drives costs past standard budgets.

Mechanical upgrades and water features also raise your final tally. Adding an attached spillover spa requires extra plumbing lines, automatic valves, a separate air blower, and a dedicated pool heater. If you want a deep end for recreation, check how deep a pool needs to be to dive safely before finalizing your layout. Deeper pools require extra excavation hours, thicker gunite walls, and larger quantities of steel rebar.

Waterfalls, deck jets, and shallow tanning ledges create a resort atmosphere in your yard. But every extra water feature requires its own plumbing runs and control valves. These additions increase the initial contract price and give you more mechanical parts to service, winterize, and repair down the road.

Factor in Ongoing Maintenance and Resurfacing Down the Road

Writing the final check to your builder does not end your pool expenses. Gunite pools cost more to maintain over time than fiberglass or vinyl liner pools because concrete is naturally porous. Algae can take root in microscopic crevices on plaster surfaces, requiring diligent brushing, frequent water circulation, and steady chemical treatment.

Your monthly electric bill will climb because the pool pump must run eight to twelve hours each day to filter the water. Choosing a variable-speed pump cuts this electrical draw, but running pool heaters and water features still adds noticeable recurring utility costs. Chemical costs also add up month after month. You need liquid chlorine, pH balancers, and algaecides to keep the water clear. Checking your water balance weekly and understanding how long chlorine lasts in a pool in hot weather prevents you from wasting expensive sanitizers while protecting your plaster from acidic water.

Routine filter maintenance also requires attention and budget. Whether your equipment pad uses a cartridge filter or a sand filter, the system needs regular upkeep to capture fine dirt. If your equipment uses a sand tank, knowing how to clean pool filter sand keeps water moving freely through your plumbing without putting dangerous backpressure on the pump motor.

The largest ongoing cost for any gunite pool owner is eventual interior resurfacing. Pool chemicals slowly strip minerals from the plaster over time, creating rough patches and stubborn stains. Every seven to fifteen years, you must pay a professional crew to drain the pool, chip away the damaged plaster layer, and apply fresh plaster or pebble aggregate. Skipping this major maintenance allows water to seep directly into the concrete shell, which can rust the internal steel rebar and cause serious structural cracks.

Follow These Steps to Compare Contractor Bids Accurately

Getting reliable prices requires comparing identical project scopes across several builders. Use these steps to review bids and protect your budget from surprise add-on charges:

1. Create an exact design wish list before calling builders: Write down your target pool dimensions, preferred depth, interior finish, coping material, and patio decking size. Providing the same specifications to every builder ensures you receive quotes based on the exact same project rather than each contractor's guesses.
2. Ask for an itemized bid instead of a single total price: A clear proposal breaks out separate costs for excavation, steel rebar reinforcement, gunite spraying, plumbing, equipment, electrical work, coping, and plaster. If a contractor offers only a lump sum total, ask them to separate the line items so you can see where your money goes.
3. Verify soil allowances and hard-dig clauses in writing: Ask each contractor how their contract handles rocky ground, buried boulders, and high water tables. Ensure the agreement lists the exact hourly rate for hydraulic rock hammers so an underground rock shelf does not cause an unexpected billing dispute.
4. Check licenses, insurance, and lien release policies: Confirm that the pool builder holds an active contractor license and carries general liability insurance and worker's compensation. Make sure the contract includes mechanic's lien waivers, which protect your home if the builder fails to pay their subcontractors or material suppliers.
5. Tie payment milestones directly to completed city inspections: Never pay large sums before work begins. A standard payment structure starts with a modest deposit, followed by progress payments released only after your local building inspector approves major construction stages, such as the steel cage inspection and the gunite shell cure.

FAQs

Can I save money by acting as my own pool builder?

Acting as your own general contractor can eliminate builder markups, but it carries substantial financial risks. You must hire and manage excavation, steel, plumbing, and gunite crews while pulling your own municipal permits. If an uninsured subcontractor makes an error or cracks an underground sewer line, you are entirely responsible for paying for the repairs.

Why is a gunite pool more expensive than vinyl or fiberglass?

Gunite pools are built entirely on site using raw steel cages, poured concrete, and custom masonry. Fiberglass pools arrive as pre-formed factory shells, and vinyl pools use lightweight wall panels with factory liners that install quickly. The heavy materials, specialized spray machinery, and weeks of skilled hand labor make gunite far more labor-intensive to construct.

Does a gunite pool increase property taxes and home value?

A permanent inground pool counts as a permanent capital improvement, which usually raises your home assessed value and your local property taxes. While a well-maintained gunite pool adds buyer appeal in warm climates, it rarely returns its full construction cost during a resale. Build a gunite pool for your family's lifestyle rather than treating it as a financial investment.

How long does it take from excavation to swimming in a gunite pool?

A standard gunite installation takes between two and four months from the start of excavation. The sprayed gunite shell needs at least twenty-eight days to cure with daily water spraying before crews can install tile, apply plaster, and fill the pool. Bad weather, permit delays, and complex decking projects can stretch that timeline even longer.
