If your Atherton pool needs resurfacing, you have three main finish options to choose from. Each has a different cost, lifespan, and look. This guide breaks down exactly what each option delivers so you can make the right call for your property.
Peninsula note: San Mateo County's water chemistry tends to be aggressive on pool surfaces. This makes finish durability more important here than in many other parts of California.
The Three Main Finish Options
White Plaster
The traditional pool finish. White cement mixed with marble dust creates a smooth, clean surface that gives pools their classic bright blue appearance. It's the most affordable option and works perfectly well — it just requires more maintenance attention and won't last as long as aggregate finishes.
- Lowest upfront cost
- Classic, timeless look
- Widely available contractors
Pros
- Shorter lifespan
- More susceptible to staining
- Needs more chemical attention
- Can feel rough as it ages
Cons
Quartz Aggregate
Quartz crystals are blended into the plaster mix, creating a surface that's dramatically more durable and stain-resistant than plain plaster. The quartz particles make the surface harder and less porous, which means less algae growth, fewer stains, and much better performance against Peninsula water chemistry. Available in a wide range of colors and blends.
- Twice the lifespan of plaster
- Superior stain and algae resistance
- Handles hard water better
- Rich color options
Pros
- Higher upfront cost than plaster
- Slight texture (not rough, just not glassy smooth)
Cons
Pebble Finish
Natural river pebbles are embedded into the plaster to create a stunning, textured surface that looks like a natural lagoon. Pebble finishes are the most durable option available and age beautifully — actually improving in appearance over time as the pebbles polish. This is the finish you see in high-end resort pools, and it's a popular choice for Atherton estate properties where the outdoor space is a focal point.
- Longest lifespan (25+ years)
- Most visually impressive
- Extremely durable and stain-resistant
- Improves with age
Pros
- Highest upfront cost
- Textured surface (some prefer smoother)
- Takes longer to install
Cons
Which Finish Makes the Most Financial Sense?
If you run the numbers on cost per year:
- White plaster at $6,000 over 11 years = ~$545/year
- Quartz at $9,000 over 20 years = ~$450/year
- Pebble at $13,000 over 25 years = ~$520/year
Quartz wins on cost efficiency while also delivering a better product. Pebble costs slightly more per year but gives you a visually superior result that adds to property value. Plain plaster is the most expensive per year of the three and provides the least durability.
What Do Atherton Homeowners Typically Choose?
The majority of Peninsula homeowners we work with choose quartz aggregate. The combination of long lifespan, strong resistance to our local water conditions, and the wide range of color options makes it the practical and aesthetic sweet spot. Pebble is popular on larger, more elaborate pools where the outdoor living area is a major part of the property.
What About Glass Bead or Other Finishes?
Some contractors offer glass bead finishes and other premium options. These are variations on the aggregate concept and can be excellent choices. If you're interested in these, ask your contractor specifically about how they perform in Peninsula water and what kind of warranty they offer — quality varies significantly by product and applicator.
