—Comparing the options
Tile or plaster for a pool interior
Tile and plaster are the two most common pool interiors. They differ in look, feel and how long they last before renovation.
Tiled interiors — ceramic, porcelain or glass mosaic — offer wide colour and pattern choice and, with sound grout and waterproofing, a long life. They are smooth and easy to clean, and individual tiles can be replaced. Initial cost is generally higher, particularly for mosaic.
Comparison guides set out how two pool options differ and when an owner might prefer one over the other.
Plaster interiors are smooth, seamless and classic, often white or tinted, giving pale blue water. They usually cost less initially but wear through chemistry and cleaning, eventually needing resurfacing. New plaster needs careful water balance while it cures. Many pools combine a tiled waterline with a plaster interior.

Comparing
Durability
Glazed tile with sound grout and waterproofing generally outlasts plaster, which wears gradually through water chemistry and cleaning.
Appearance
Tile offers colours, patterns and mosaics; plaster gives an even, seamless colour that makes the water look soft and pale.
Feel
Both smooth when new; plaster roughens with age.
Repairs
Single tiles can be replaced; plaster is patched or resurfaced.
Cost
Plaster usually lower initially.

—In practice
How to use this
Compare the two on initial cost, appearance, feel underfoot and how often each typically needs renovating. Consider how long you plan to keep the pool and how much maintenance you are willing to accept. View samples under water, and ask how repairs are handled for each, since individual tiles can be replaced while plaster is usually redone in areas.
Mistakes worth avoiding
- Choosing on initial cost only
- Renovation cycles affect the long-term cost of a finish. A cheaper start can mean an earlier and larger bill.
- Forgetting how it feels
- Finish texture matters for bare feet, children and anyone sitting on steps. Feel samples as well as looking at them.
04FAQ
Common questions about this
- Which lasts longer?
- Well-installed tile usually lasts longer.
- Is plaster rough?
- Smooth when new; it roughens as it wears.
- Can I switch later?
- Yes, at renovation time.
- Does plaster stain?
- It can, more readily than glazed tile.
- Which finish is easier to clean?
- Glazed tile is generally easier, since dirt and scale sit on a smooth, non-porous surface.
