Custom Pool Builder in Katy, TX

Pool Builder Serving Katy, TX

Aquascapes Pools is a family-owned custom gunite pool builder serving Katy, Texas from our display center in Tomball, roughly 35 miles north of town. We design and build inground pools, spas, water features, and complete outdoor living spaces for homeowners across Cinco Ranch, Cross Creek Ranch, Katy Lakes, Firethorne, and the surrounding Katy area — and every phase, from 3D design through gunite, decking, and startup, is handled by our own crews rather than subcontracted out.

Two things separate a Katy pool build from a build anywhere else in greater Houston: the ground it sits in, and the county that permits it. Katy sits on the eastern edge of the Katy Prairie, where the soil is heavy, expansive clay and the land is close to flat. Katy also straddles three counties. Get either of those wrong and you inherit problems that surface years later. We plan for both before a shovel touches the yard.

Building on Katy Prairie Clay

The Katy Prairie is old coastal grassland and former rice farmland, and the soils under it are dense, slow-draining clays that swell when they take on water and shrink back when they dry out. That seasonal movement is what cracks pool shells, separates coping, and heaves decking on pools that were not engineered for it.

Our answer is not a heavier plaster coat, it is structure. Katy-area builds get soil-appropriate steel reinforcement schedules, shell thickness specified for the site rather than a default, and a drainage plan drawn for a lot that does not shed water quickly on its own. Because Katy grades are flat and the clay underneath holds water, deck drainage, area drains, and where runoff actually goes matter as much as the pool itself. A beautiful pool sitting in a yard that ponds after every storm is a problem we would rather design out at the start.

Katy Permitting: Harris, Fort Bend, and Waller County

A Katy mailing address does not tell you who issues your pool permit. Properties inside the Katy city limits permit through the City of Katy. Everything else falls to the county, and Katy addresses spread across all three: unincorporated Harris County on the east and north, Fort Bend County to the south, and Waller County to the west and northwest.

Broadly, Cinco Ranch sits largely on the Fort Bend County side, Cross Creek Ranch falls in Fort Bend County out toward Fulshear, Firethorne straddles the Waller and Fort Bend line, and newer sections like Katy Lakes sit in Waller County. Each jurisdiction has its own submittal package, review timeline, inspection sequence, and barrier and enclosure requirements. We confirm which authority governs your specific address before design is finalized and handle the permitting in-house, so you are not the one chasing three different county offices.

Some Katy lots carry an extra layer. Parts of the area sit inside FEMA-mapped floodplain or within the Addicks and Barker reservoir flood pools east of town, and building there can require additional drainage review, elevation documentation, and detention considerations. If your lot falls into that category, we will tell you early and work it through with the applicable county rather than discovering it mid-build.

MUD Districts and HOA Approval

Most Katy-area neighborhoods are served by Municipal Utility Districts rather than a city utility, and nearly all of them sit under an HOA with an architectural control committee. Practically, that means two things for your project: your water source and any drainage tie-in follow MUD rules, and your pool design, decking, fencing, and equipment screening typically need ACC approval before construction starts.

We build the HOA submittal into the schedule instead of treating it as an afterthought. Our 3D design package is generally what the committee wants to see anyway, so the same renderings you use to make decisions are the ones that go to your ACC.

What We Build in Katy

Every Katy pool we build is gunite — steel-reinforced concrete sprayed in place. We do not install fiberglass shells. Gunite means the shape, depth, and features are genuinely yours rather than chosen from a catalog of pre-formed molds, and it is the construction method that holds up best in expansive Texas clay.

• Custom pools and spas — freeform and geometric designs, spillover and raised spas, tanning ledges, and lap-friendly layouts
• Custom features — waterfalls, grottos, fire bowls, bubblers, deck jets, and color-changing LED lighting
• Outdoor living — outdoor kitchens, covered patios, pergolas, fire pits, and decking designed alongside the pool
• Pool renovations — resurfacing, retiling, new decking, and equipment upgrades for older Katy pools

What a Custom Pool Costs in Katy

Across the Katy and greater Houston area, custom gunite pools generally run from about $50,000 to $150,000 or more. Larger builds with extensive decking, an outdoor kitchen, multiple water features, and full automation can run past that range. Where your project lands depends on:

• Pool size, shape, and depth
• Spa type, whether attached, spillover, or raised
• Interior finish, from plaster to pebble to glass tile
• Decking material and total square footage
• Site conditions, including clay soil, drainage work, and access for equipment
• Water features, lighting, heating, and automation
• Which jurisdiction permits the work and whether the lot needs added drainage review

Access is worth calling out in Katy specifically. Many newer Katy subdivisions are built on tight lots with narrow side yards and close setbacks, which affects how excavation equipment and gunite hose reach the backyard. We assess that on the walkthrough, because it is a real cost variable and not one you want discovered later.

The only way to get an accurate figure for your yard is a no-obligation consultation. We walk the property, talk through budget honestly, and put together a detailed proposal.
