Most Houston and Katy Pools Cost $65,000 to $175,000
In 2026, most custom gunite pools from Houston and Katy pool builders cost $65,000 to $175,000. A small plunge or cocktail pool starts around $20,000, and estate builds with vanishing edges and full outdoor living pass $300,000. Remodeling an existing pool is a different budget: resurfacing alone runs $6,000 to $15,000.

| Build Type | Typical 2026 Range | What Moves the Number |
|---|---|---|

What Houston Custom Pools Cost in 2026
The widest swing in pool pricing comes from size, finish, and features — not from the builder’s zip code. These tiers reflect 2026 Texas and Greater Houston market ranges for custom gunite construction, so you can anchor on realistic numbers before your first design meeting.
| Tier | Typical Range | What’s Included |
|---|---|---|
| Entry-level custom gunite | $65,000 – $100,000 | Standard shell, basic plaster finish, standard equipment, basic decking |
| Mid-range with features | $100,000 – $175,000 | Larger shell, spa, water features, upgraded tile/finish, expanded decking |
| High-end / estate | $175,000 – $300,000+ | Vanishing edges, premium finishes (pebble, glass tile, natural stone decking), full outdoor living integration |
$100–$280 per Square Foot for Custom Gunite
Custom gunite pools in the Houston market generally price between $100 and $280 per square foot depending on the finish tier and feature set. A word of caution on the numbers you’ll see elsewhere online: the broader “in-ground pool” averages of $50–$125 per square foot reflect basic vinyl and fiberglass shells — not custom gunite construction.
Anchoring on the wrong benchmark is the most common way homeowners end up surprised at quote time. If you’re pricing a fully custom, engineered gunite pool with premium finishes, use the gunite range — that’s the product you’re actually buying.
- Size and depth — more water, gunite, and excavation move the number most directly
- Shell material — custom gunite prices differently than fiberglass or vinyl-liner shells
- Finish tier — plaster vs. pebble vs. glass tile, and premium decking at $18–$28+ per square foot
- Water features, spas, and automation — each adds equipment, plumbing, and electrical scope
- Site conditions — tree removal, drainage, and backyard access for excavation equipment
- Combining the pool with a patio, outdoor kitchen, or lighting in one build — usually more cost-efficient than adding them later
What Common Pool Sizes Cost in Houston.
Homeowners usually start with a size in mind. This table applies the $100 to $280 per square foot range to the sizes we are asked about most, with the entry-level floor that applies to any custom gunite pool.
| Pool Size | Surface Area | Typical Custom Gunite Range |
|---|---|---|
| 12 x 24 ft | 288 sq ft | $65,000 – $80,000 |
| 15 x 30 ft | 450 sq ft | $65,000 – $126,000 |
| 16 x 32 ft | 512 sq ft | $65,000 – $143,000 |
| 20 x 40 ft | 800 sq ft | $80,000 – $224,000 |
Ranges are planning figures, not a quote. Finish tier, a spa, water features, decking area, and site access decide where a pool lands within its range.
Why a Smaller Pool Is Not Proportionally Cheaper
Excavation equipment, the equipment pad, permits, plumbing, electrical, and startup cost about the same whether the shell is 288 square feet or 500. That is why small custom gunite pools cluster near the entry tier instead of scaling down with size.
For tight lots, a purpose-designed plunge pool or cocktail pool is the format built around a small footprint. Our guide to plunge pool cost factors and sizes covers how to tell whether one fits your yard.
What $30,000 and $100,000 Buy
At $30,000, the Houston market offers small fiberglass or vinyl-liner pools and basic plunge pools, not full-size custom gunite. Across Texas, gunite pools average about $71,000, fiberglass about $54,000, and vinyl-liner about $43,000 before features and decking.
At $100,000, most homeowners get a mid-size gunite pool with a tanning ledge or spa, upgraded tile and finish, LED lighting, and automation. When you compare custom gunite pool builders in Houston, ask each one to itemize the shell, finish, equipment, and decking so the quotes line up against these tiers.
Soil, HOA Review, and Permits in Katy and Houston
The pool itself prices the same on either side of the metro. What changes between a Katy master-planned community and a lot inside Houston city limits is the paperwork, the approval path, and the site work around the shell.
Soil and Site Work
Katy and Houston both build on Gulf Coast clay soils and take hard summer rains, so steel, drainage, and how the deck sheds water are engineered into every quote. Tight inner-loop access or mature trees cost more than an open suburban backyard.
HOA Design Review
Katy communities such as Cinco Ranch, Cross Creek Ranch, Firethorne, and Seven Meadows typically add architectural review before the permit is filed. It mostly adds time, not cost; we prepare and submit the package.
Who Issues the Permit
Much of the greater Katy area is unincorporated, so a Katy pool is permitted by the City of Katy or the county depending on the address. Houston addresses go through the city or Harris County, as broken down below. See our Katy pool builder page for more on building there.
Permit Costs Vary by Jurisdiction
Action Custom Pools builds in incorporated Houston, unincorporated Harris County, and suburbs that run their own building departments — and each prices permits differently. We handle all permitting as part of every project, regardless of jurisdiction.
City of Houston
Plan review plus permit fees total around $275 — a $94.00 residential plan review and a $181.28 pre-operational inspection fee per the City of Houston fee schedule.
Unincorporated Harris County
$131.25 per pool/spa permit per Harris County Public Health. Most master-planned suburbs — Katy, Cypress, and similar — also layer HOA design review on top.
Cities With Their Own Building Departments
Cities like West University Place run a more detailed — and higher-cost — permit packet, including surveys and neighbor notices. See our West University Place page for specifics.
