Waterline pool tile has an important role in keeping your swimming pool looking great.

That’s because, over time, calcium deposits and mineral buildup can form around the perimeter of your pool, due to hard water, which detracts from your pool’s overall appearance. This permanent white ring is much easier to remove from tile than cement-based rendered surfaces.

Additionally, waterline pool tile helps prevent pollen, sunscreen, body oils, and other substances that enter the water from creating a yellow, scummy line at the pool’s waterline. 

The Something Extra of Glass Pool Tile

Glass pool tiles not only do all the aesthetic things correctly, they also provide a WOW factor not found in other types of tile used for waterlines. In recent years, glass mosaic tile has become a popular choice for waterline tile because of the way it captures sunlight and mirrors the water’s movement.

It’s not unusual for designers to report that homeowners often feel a strong emotional response to their glass tiles. The impact of mosaic tile waterlines has been compared to looking at cut diamonds. When you look at a cut diamond there’s a complex optical system where light enters the structure and then reflects back out through the facets. Glass tile works much the same way optically and can create a similar emotional uplifting.

Additionally, with glass mosaic tile, that visual complexity often shifts depending on the angle of the sun or other lighting source and the depth of the water. This gives the pool or spa an ever-changing appearance which, in turn, can provide continually refreshed visual interest.

Mosaic tile has also been compared to pointillism used by impressionist painters. Each glass tile in the waterline is a single dot, but when combined with others, it creates a new blended color submerged in water and seen even from a short distance.

Glass Tile’s Amazing Selection

Glass pool tile’s popularity as a waterline tile is also due to the large selection of colors and transparencies available. There’s also a variety of effects such as pearl, crystal and gold.  Mosaic glass tile’s shimmer and sparkle goes a long way to bringing a pool to life.

AquaBlu Mosaics also offers a substantial line of mosaic glass tiles suitable for waterlines. Take Aquatica’s Aegean glass pool tile in the Garden Wall collection. This blended blue glass tile makes the pool bluer by using a dark blue waterline tile with a light-colored interior. This perfect waterline tile also helps prevent a dry, washed out look between the coping and the water that you can get with render finishes.

For an especially pleasing visual effect, choose a lifelike mosaic tile centerpiece like a dolphin or tile medallion with the same complimentary colors as the Aegean blue glass tile. There’s nothing like it from a design standpoint. 

Installing Glass Pool Tile Waterlines

The installation process of glass tile is more labor intensive, but the results are unique and not found with any other type of tile. 

When installed properly, most types of glass tile represent the most durable of all swimming pool and spa surfaces; they offer sturdy resistance to chemical corrosion and other types of damage. Compared to other interior swimming pool and spa surface materials -- such as plaster, exposed aggregate or fiberglass finishes, which typically last anywhere from five to 25 years -- glass tile surfaces can retain their appearance and surface integrity almost indefinitely.

Cleaning Glass Mosaic Tile

On a practical level, glass tiles are easier to clean than cement-based rendered surfaces such as pebblecrete used in concrete pools. Waterline tiles greatly increase the ease of cleaning the dirt that deposits on the walls of the pool at the waterline.

In cases where your dirt and grime is only minimal, you can use homemade cleaners as such vinegar with water, baking soda and vinegar, toothpaste or even dish soap to remove the deposits.

Also, when pool water naturally evaporates, calcium deposits can attach to the sides. This calcium scaling will appear as a white-gray colored scum. Generally speaking, there are two types of scaling you may find on your waterline pool tiles:


Using a stiff brush, clean away the calcium carbonate working quickly in circular movements. If the buildup is minimal and you are working in smaller areas, you can also try a toothbrush which is gentle on glass tiles.


Calcium silicate is the more difficult types of scaling scum. For tough stains or calcium silicate scaling, you’ll need to clean the area using a pumice stone. To prevent scratching, it is important to work gently and keep the tiles and the pumice stone wet while you are scrubbing.
