Custom Pool Builder — Seguin, TX
Custom Pool Builder
Built to Last.
I'm Coy Turner. I build custom homes and custom pools for families in Seguin and the surrounding Hill Country. Every pool starts with your lot — not a catalog. And I build them in about 8 weeks, not 6 months.
Built to Order
Built for Your Lot,
Not a Catalog.
Every backyard I've ever worked with is different. Flat. Sloped. Full of limestone rock under the topsoil. Shaded by live oaks you’re not willing to cut. A drainage pattern that sends rainwater toward your foundation.
That's why I don't start with a pool template. I start with your ground.
Turner Custom Pools is a gunite pool builder grounded in 15+ years of custom home construction. That means your pool gets the same structural thinking I'd put into a house — thicker shells where the soil demands it, smarter plumbing layouts, rebar that crosses in two directions where load-bearing matters.
Pools aren't decorations. They're 30-year structural projects. I build them like one.
Your pool should outlast your mortgage.
Thicker shells, better steel, smarter plumbing, and materials chosen for decades, not a price point. This isn't a backyard accessory — it's a 30-year investment, and we build it like one.
“After 15 years building custom homes in Seguin, pools were a natural next step. Your backyard deserves the same engineering and craftsmanship as your kitchen or living room — I just couldn't see building it any other way.”
— Coy Turner
Real Timelines
The 8-Week Build (No, Really)
I don't say this to hype things up. Eight weeks from design lock to water in the pool is the real timeline, and it works because I plan the whole thing before I break ground.
Most pool companies start planning when they start digging. They figure out subs, materials, and permits as the project unfolds. That's why their builds drag into four, five, six months.
I've been building custom homes long enough to know that the building happens on paper first. Your pool design is locked, permits submitted, materials ordered, and crews scheduled before the first shovel touches your yard.

Hill Country Dirt Requires
Different Building.
Hill Country soil isn’t flat, it isn’t consistent, and it moves — drying out in August, swelling back in October. Limestone and caliche mean excavation isn’t just about digging a hole. It’s about navigating rock, managing drainage, and designing for a foundation that shifts.
Fiberglass pools snap under this stress. Concrete (gunite) flexes with the ground. I’ve spent 15 years building structures in this terrain. Your pool gets that know-how.

“You can't cookie-cutter a Hill Country backyard. Every pool starts with understanding your specific piece of Texas.”

Quick Answers
FAQ — Quick Answers
How long does it take to build a pool?+
About 8 weeks from the time your design is locked and permits are in. Not 4 or 6 months. Design-lock means we plan everything — permits, materials, crew schedules — before we dig. That's how we move fast without cutting corners.
Do you build outside of Seguin?+
Yes. Seguin is my home base, but I regularly build in McQueeney, Marion, La Vernia, and all of Guadalupe County. I know the permits and the soil in each of these areas.
Why do you only build gunite?+
Fiberglass pools crack under Hill Country soil stress — the limestone, caliche, seasonal swelling. Gunite (sprayed concrete over steel rebar) is custom and flexible. It moves with the ground instead of against it. I've seen fiberglass pools crack in this terrain. I won't put one in your backyard.
Can I reach you directly during my build?+
Yes. Coy is your builder, your project manager, and your phone call. You don't go through a sales department or leave a message for someone who started last month.
