How to Choose the Best Waterline Pool Tiles in 2025

Waterline pool tiles can be found where the water level meets the pool wall. They are installed around the upper edge of a swimming pool and serve both functional and aesthetic purposes. 

Functionally, waterline pool tiles help prevent the buildup of calcium deposits, algae, sunscreen, and other residues that typically form at the waterline, similar to how a bathtub ring forms. Removing buildup and maintaining cleanliness with waterline tiles is much easier than scrubbing it off plaster.

Aesthetically, waterline tiles frame the pool, creating a visually appealing boundary and add a finished look.

But if you’re new to the pool tile industry, selecting and buying waterline pool tiles might seem overwhelming. That’s where Oasis Tile can help. From advising you on the best tile for your pool waterline to the newest deck pool tile trends, we have the experience and the inventory to assist you in making the right decision for your needs. 

Why do I need waterline tile in my pool?

Technically, a pool needs waterline tiles, yet many suppliers argue differently, saying a pool without waterline tile is OK. 

Simply put, a swimming pool without waterline tiles may experience problems leading to expensive repairs or the need for a complete retilling. Not only do these pool tiles prevent the buildup of scum but they also keep the pool’s shell or liner sealed. Having an airtight liner or shell prevents problems like cracking, erosion or freezing of pool water, which can result in substantial damage to a pool.

What to Consider When Choosing Waterline Tiles?

Several factors must be considered when choosing waterline pool tiles, including color, material, design, and size. Understanding how to choose pool tile ensures you select the best option for durability, aesthetics, and maintenance. 

Material

The material of your waterline pool tiles affects their durability, appearance, and maintenance. The most common is porcelain pool tile, which has many benefits, including unrivaled durability. As a very dense material of clay fired at a very high temperature, porcelain is highly resistant to scratches and stains and constant water exposure. For example, our Florencial Torciano Maze Black 8x8 Matte Porcelain Tile embodies the Mediterranean pool tile trend while providing strength and style. This durability keeps them looking good for years and prevents them from cracking or falling off long after installation. 

Glass pool tile, such as the infinity pool trend of green tiles like our Elegant Swirl Deepsea Current Green 3x12 Glossy Glass Subway Tile, provides a luxurious and elegant feeling and is reflective. For saltwater pools, glass tile is the best choice because it is non-porous, highly resistant to corrosion, and unaffected by salt exposure, ensuring long-lasting beauty and durability. Glass tiles are eye-catching and available in vibrant colors, iridescent like our best selling, Mykonos Harbor Zeus Landing Grey 1x2 Iridescent Rippled Frosted Glass Pool Tile. 

Pebble or textured tiles such as our Liquid Rocks Abyss Black Glass and Stone Pebble Tile can create a natural, lagoon-style, or tropical look for your pool. This style of pool tile often offers better grip and slip resistance than smooth lines and blends well with natural pool surroundings.

Color

The best color for pool waterline tile complements the overall design of your pool and outdoor space. Picking the right tile color is essential, as lighter colors, such as our Watercraft Coral Reef Blue 1x2 Stacked Glossy blue tile, can make your water look bright and inviting. Darker colors such as our Evelon Drake Black 3x16 Glossy Porcelain Tile raise the level of sophistication and can create a high-end and dramatic look. Mosaic pool tiles like our Super Nova Brick 1x2 Glossy and Iridescent Glass Tile add visual appeal to your water and create unique patterns and reflections.

Durability and Maintenance

Durability is a tremendously important factor when researching pool waterline tile ideas. Your selection should resist chipping, fading, and cracking, ensuring long-lasting beauty and performance. As previously mentioned, non-porous materials, such as porcelain or glass, are ideal, as they help prevent algae and mold buildup and are easy to maintain. Also, double-check to ensure the pool tiles can withstand the harsh chemicals and UV rays and maintain their appearance over time. Choosing durable tiles like our White Glossy 1x1 Glass Tile, a popular choice in both luxury and white pool tile trends, can help you save money on repairs and replacements in the long run.

Size

The most common waterline pool tile size is 6x6, but it’s also available in smaller sizes of 3x3, 2x2, 1x2, 3x12, and even 1x1. Tile size significantly impacts the pool’s appearance, with smaller tiles (1x1 or mosaics) creating intricate patterns and a seamless look. In comparison, larger tiles like our 6x6 Serene Sea Blue Glossy Porcelain Tile—a popular pool tile trend, offer a more modern and clean aesthetic with fewer grout lines making maintenance easier.

When considering proportions, smaller pools look better using smaller tiles, including around the pool border. At the same time, larger pools can accommodate more oversized tiles for a bold, streamlined appearance.

For a more unconventional pool tile idea, why not try mixing different sizes, such as installing mosaic glass pool tile and combining it with smaller porcelain accents.

Cost

Whether investing in pool waterline tile replacement or buying for the first time, referring to our pool tile buying guide can help you choose the right tile material based on durability, aesthetics, and maintenance. The cost depends on tile material, pool size, and labor charges. In 2025, the average cost is about $25 per linear foot, with materials ranging from $1–$100 per square foot, porcelain, which is the most affordable, while glass and natural stone (granite, marble, travertine, and limestone) vary in price.

Labor costs usually range from $30 to $120 an hour or $4 to $32 per foot, depending on the complexity of the project and the location. For a 10x20-foot pool, installation can cost around $1,500. Additional expenses may arise due to intricate designs, tile removal, or regional labor rates, so it is recommended that you talk with a local contractor for an exact quote.
