TLDR
Standard plaster ($5,000-$8,000) lasts 10-15 years and offers smooth, classic appearance. Pebble finishes ($8,000-$12,000) last 15-20 years with superior durability and texture. Aggregate finishes ($10,000-$15,000) provide the longest lifespan with premium aesthetics but highest cost.
Traditional Plaster: The Classic Choice
White or colored plaster remains the most popular pool finish due to its smooth texture and lower cost. The installation process applies a layer of cement mixed with marble dust or limestone, creating that classic pool look everyone recognizes. White plaster gives water a bright, traditional blue appearance, while colored plasters (grays, blues, greens) create different water hues and can hide minor staining better than white.
The smooth surface feels great on skin and looks elegant, but it's the most fragile option. Plaster requires meticulous water chemistry maintenance—improper pH levels etch and erode the surface prematurely. Expect 10-15 years of life with excellent care, potentially less with poor maintenance or aggressive water conditions. The lower upfront cost appeals to budget-conscious homeowners, but more frequent replacement means higher lifetime costs.
Pebble and Aggregate: Premium Durability
Pebble finishes incorporate small stones into the plaster mixture, creating a textured, natural appearance. The tiny pebbles (or "aggregates") create a harder, more durable surface that resists etching, staining, and wear significantly better than standard plaster. Lifespans of 15-20 years are typical, and the finish maintains its appearance throughout. The textured surface provides excellent traction, reducing slip hazards on steps and ledges.
Pebble finishes offer extensive color and size options. Small pebbles create a more refined look and smoother feel, while larger aggregates make bolder statements. Colors range from whites and creams to blacks, blues, and mixed tones. The reflective qualities of the stones create depth and shimmer in the water that flat plaster can't match.
The trade-offs are cost and texture. Pebble finishes cost $8,000-$12,000 or more, roughly double standard plaster. The textured surface feels rougher than smooth plaster—not uncomfortable, but noticeably different. Some swimmers with sensitive skin or young children may find extended contact less comfortable than smooth finishes.
Glass Bead and Quartz: The Premium Tier
Glass bead and quartz finishes represent the top tier of pool surfaces. These finishes incorporate crushed quartz crystals or tiny glass beads, creating incredibly smooth, reflective surfaces that sparkle underwater. They're nearly as smooth as traditional plaster but with durability approaching pebble finishes. The appearance is stunning—light reflects off thousands of tiny surfaces, creating a jewel-like effect.
Expect to pay $10,000-$15,000 or more, making these finishes the most expensive option. However, the longevity (20+ years potential) and low maintenance requirements offset the higher initial cost over the pool's lifetime. These finishes resist staining and algae growth better than any other option and maintain their appearance with minimal effort.
