New project. This time, we’re not building the pool from scratch. We’re giving the existing one a whole new look. 👊

We’re starting a new remodel where we’ll be adding a Baja shelf, installing new tile, and putting in a new fence around the pool.

That Baja shelf alone is going to change how the homeowners can use the pool, giving them a shallow area to relax, lounge, and enjoy the water without having to be completely in it.

Then the new tile and fencing will help bring the rest of the space together.

We’re just getting started. Can’t wait to show you how this one turns out.

Tile day started with a decision. 👀

Before installing everything, we needed to figure out exactly how we wanted the pattern to lay out across the pool.

It may seem like a small detail, but once all that tile is installed, you want the pattern to look intentional from one end to the other.

That’s why we take the time to lay things out, step back, look at it, and make adjustments before committing.

A lot of custom pool building comes down to decisions like this that the homeowner may never think about once they’re enjoying the finished backyard.

But we think about them now so they don’t have to later.

to laugh…
to build memories together…

Behind every beautiful home…
every birthday party…
every late-night swim…
every summer memory…

there’s usually a mom somewhere in the story.

The ones who hold everything together.
The ones who make a house feel like home.
The ones who create warmth, comfort, laughter, and moments families never forget.

Today we celebrate the real builders of memories.

Happy Mother’s Day from all of us at Custom Built Pools & Spas. ❤️

Construction rule #1:
the smallest things hurt the most 😭😂

Not the heavy equipment.
Not the concrete.
Not the long hours.

A tiny screw said:
“nah… today’s my turn.”

And just like that—
the piece of wood got permanently banned from the job site 💀

This isn’t your average backyard project. 👀

Take a behind-the-scenes look at one of the most exciting custom builds we’ve worked on — a lazy river project by Custom Built Pools & Spas.

From walking the job site and planning the details to meeting with the client and bringing the vision to life, this is just the beginning of something special.

Every project starts with an idea…
and this one is on a whole different level.

Stay connected as we document the full process from the ground up.

It’s a small detail… until it’s not.

Coping frames the entire pool. It defines the edge, the flow, the feel under your feet.

Get it right, and everything looks intentional. Get it wrong, and something always feels off.

Clean lines. Smooth transitions. That’s where the beauty is.
