Pool Finish Guide: PebbleTec vs Plaster Explained

Choosing the right pool finish is one of the most important decisions you’ll make when building or renovating a swimming pool. The finish determines not only how your pool looks, but also how long it lasts, how much maintenance it requires, and how comfortable it feels underfoot. Two of the most common options homeowners consider are PebbleTec and traditional plaster. Both have their strengths, but they offer very different experiences in terms of durability, aesthetics, and long‑term value.

If you’re planning a custom pool in New Braunfels, Boerne, San Antonio, or the surrounding Texas Hill Country, this guide breaks down everything you need to know to make the right choice.

What Is Plaster?

Plaster—often called marcite—is the classic pool finish. It’s made from a mixture of white cement, marble dust, and water. When applied correctly, plaster creates a smooth, bright surface that gives pools that clean, traditional blue‑water look.

Benefits of Plaster

• Smooth texture that feels comfortable on feet and hands
• Lower upfront cost compared to premium finishes
• Classic aesthetic that many homeowners love
• Wide availability and quick installation

Drawbacks of Plaster

• Shorter lifespan — typically 5–10 years
• More prone to staining from minerals and chemicals
• Can etch or discolor if water chemistry isn’t perfectly maintained
• Requires more frequent resurfacing

Plaster is a good option for homeowners who want a clean, simple look and are working within a tighter budget. However, it does require more maintenance and doesn’t hold up as well to Texas heat and hard water.

What Is PebbleTec?

PebbleTec is a premium pool finish made from natural river pebbles blended with cement. It’s known for its durability, texture, and upscale appearance. As a certified PebbleTec installer, J. Oliver Custom Pools & Design uses this finish in many of our luxury pool builds.

Benefits of PebbleTec

• Exceptional durability — often lasting 20+ years
• Natural, upscale appearance with rich color options
• Highly stain‑resistant and less affected by chemical imbalance
• Slip‑resistant texture ideal for tanning ledges and shallow areas
• Low maintenance compared to plaster

Drawbacks of PebbleTec

• Higher upfront cost than plaster
• Slightly textured feel that may be noticeable to sensitive swimmers
• Requires certified installers to ensure proper application

PebbleTec is designed for homeowners who want a long‑lasting, luxury finish with minimal upkeep.

Durability: PebbleTec Wins by a Wide Margin

When it comes to longevity, PebbleTec is the clear leader. Plaster finishes typically last 5–10 years, depending on water chemistry and usage. In contrast, PebbleTec finishes often last 20 years or more with proper care.

Why PebbleTec Lasts Longer

• Natural pebbles don’t degrade the way marble dust does
• Less vulnerable to chemical imbalance
• Resists etching and pitting
• Holds color better over time

Texas pools face intense UV exposure, high temperatures, and mineral‑heavy water. PebbleTec stands up to these conditions far better than plaster.

Aesthetics: Classic vs. Custom Luxury

Both finishes offer beautiful results, but they create very different visual styles.

Plaster Aesthetic

• Bright, smooth, classic look
• Limited color options
• Water appears light blue

PebbleTec Aesthetic

• Natural, organic appearance
• Dozens of color blends from light to dramatic dark tones
• Reflective pebbles create shimmering water
• Customizable textures and finishes

If you want a resort‑style pool with depth, dimension, and a high‑end feel, PebbleTec offers far more design flexibility.

Comfort: Smooth vs. Textured

Plaster is known for its smooth feel, which many swimmers enjoy. PebbleTec has a naturally textured surface due to the pebbles, though modern application techniques have made it much more comfortable than older pebble finishes.

Comfort Comparison

• Plaster: Very smooth but becomes rough as it ages
• PebbleTec: Lightly textured but stays consistent for decades

For families with young children, both finishes are suitable, but PebbleTec’s slip‑resistant surface can be an advantage on steps and shallow areas.

Maintenance: PebbleTec Saves Time and Money Long‑Term

Plaster requires more frequent brushing, chemical balancing, and resurfacing. It’s more sensitive to pH swings and mineral buildup, which can cause discoloration or rough patches.

PebbleTec, on the other hand, is extremely low‑maintenance.

Maintenance Comparison

• Plaster:
• Frequent brushing to prevent algae
• More chemical adjustments
• Higher long‑term cost due to resurfacing
• PebbleTec:
• Minimal brushing
• Resists staining
• Lower lifetime cost

If you want a finish that stays beautiful with less effort, PebbleTec is the better choice.

Cost: Upfront vs. Lifetime Value

Plaster is less expensive initially, making it appealing for budget‑conscious projects. PebbleTec costs more upfront but pays off over time due to its longevity and reduced maintenance.

Cost Breakdown

• Plaster:
• Lower initial cost
• Higher long‑term cost due to resurfacing every 5–10 years
• PebbleTec:
• Higher initial investment
• Lower lifetime cost thanks to durability

For homeowners planning to stay in their home long‑term, PebbleTec often ends up being the more economical choice.

Which Finish Is Best for Your Pool?

Both finishes have their place, but the right choice depends on your priorities.

Choose Plaster If You Want:

• Lower upfront cost
• A smooth, classic look
• A simple finish for a budget‑friendly build

Choose PebbleTec If You Want:

• A luxury, resort‑style appearance
• A finish that lasts 20+ years
• Low maintenance and high durability
• Rich color options and natural texture

Final Thoughts

For most Texas homeowners—especially those investing in a custom luxury pool—PebbleTec offers the best long‑term value, durability, and aesthetic appeal. While plaster remains a solid budget option, it simply can’t match the lifespan, beauty, and performance of a PebbleTec finish.
