You wouldn’t build a house and skip the walls. So why finish a pool without thinking seriously about the plaster?

Pool plaster is more than just a pretty finish. It’s your pool’s skin. It seals the structure, gives it color and texture, and most importantly—protects everything underneath. And if it fails? You could be looking at a whole lot more than just cosmetic repairs.

Let’s break down what you’re really paying for, what your options are, and how to avoid the biggest mistakes homeowners make.

What Is Pool Plaster (Really)?

Technically, plaster is a mix of cement, sand, and sometimes crushed stone or quartz. But to a pool owner, it’s the barrier between your beautiful backyard oasis and an expensive structural issue.

The plaster is what makes your pool feel smooth or a little texture to the touch, gives it color, and keeps the water where it belongs. Over time, it will age—sometimes gracefully, sometimes not. That’s why choosing the right plaster and getting it installed properly matters more than most people realize.

Types of Pool Plaster (and How They Stack Up)

• Standard White Plaster ($6–$8/sq ft): Clean, smooth, classic. Most affordable. But prone to staining and etching if not cared for.
• Quartz Finish ($7–$9/sq ft): Adds durability and sparkle. Tougher than standard plaster and holds color better over time.
• Pebble Finish ($14–$18+/sq ft): The luxury choice. Textured, natural look with the longest lifespan. You’ll feel it on your feet—some love it, some don’t.

Ballpark Plastering Costs by Pool Size:

• Small pool: $3,000 – $4,500
• Medium pool: $5,000 – $6,000
• Large pool: $6,000 – $10,000+

But keep this in mind: two pools the same size can have wildly different costs depending on what lies beneath. Here are 6 that will add cost.

6 Things That Jack Up the Price (That No One Tells You)

1. Pool Shape & Size: Curves, angles, deep ends—more surface means more materials, and tricky geometry means more time.
2. Steps, Benches & Bar Stools: These require finesse and time. Not to mention if they have tile targets or stem trim. Expect added labor costs.
3. Color Choice: Deep blues and blacks? Gorgeous, but higher maintenance and cost.

1. In-Floor Systems: These nozzles in the floor, steps, and benches will need to be worked around which causes extra time and labor.
2. White Goods: Every return jet, skimmer, or spa jet that has to be touched adds parts and labor.
3. Plaster Mess: If a company or crew is not clean with their work, they can cause a real mess everywhere and therefore will need to be cleaned up by someone else who will charge for the cleanup.

Why It Matters (and What Can Go Wrong)

Done right, plaster gives you a decade or more of trouble-free swimming. Done wrong? You might see cracks, rough surfaces, or even leaks in just a couple of years.

We recently had a homeowner call us after just three years with another contractor’s job. The surface was rough, the color was blotchy, and they had leaks they couldn’t trace. Turns out the original crew skipped a bonding coat and didn’t prep the shell correctly. We had to strip everything back to the gunite shell and start over. It wasn’t cheap—but it was the only way to do it right.

The takeaway? A cheaper plaster job is rarely a cheaper pool.

Our Take

We believe in doing it once and doing it right. That’s why we use trained crews, time-tested materials, and walk you through every step—from shell to swim. Because once that water goes in, we want you thinking about summer memories, not surface problems.

Let’s build something strong, beautiful, and built to last.
