When it comes to designing your dream pool, every detail matters. One crucial aspect that often gets overlooked is the selection of the waterline tile. The waterline tile not only enhances the visual appeal of your pool but also serves a practical purpose of protecting the pool walls from water damage. In this comprehensive guide, we will explore the key factors to consider when choosing the waterline tile for your pool, ensuring that your pool stands out and captures attention.

What is the Pool Waterline?

Understanding the Importance of Waterline Tile Selection

The waterline tile plays a vital role in both the aesthetics and functionality of your pool. It acts as a transition between the water and the pool’s interior, creating a visually appealing boundary. Additionally, the tile serves as a protective barrier, preventing water from seeping into the pool walls and causing potential damage. Choosing the right waterline tile will not only elevate the overall design but also contribute to the durability and longevity of your pool.

What is a Waterline Pool Tile & Why Do I Need it?

Waterline tile is the tile installed near the top of the pool wall, right beneath the coping. The standard size for a waterline pool tile is 6” (the band can be wider as well), and it runs around the entire perimeter of the pool. When making decisions about a new pool and selecting various materials and options, the waterline tile tends to get overlooked at times. When the time to pick one finally comes, it ends up being a hurried decision. Our suggestion, talk to your contractor/designer and make lists of things you need to decide on. That would ensure ample time for research of available materials, and minimize regret.

The waterline pool tile helps you protect the pool wall against certain deposits and stains. Think of shower walls and backsplash tiles. Waterline tiles are easy-to-claim and require low maintenance, making it the perfect prevention for an unsightly potential problem.

What is that gunk anyway?

A variety of substances floating on the surface of pool water can cause residues and stains along the waterline. Following are some of the most common ones:

  • Organic and Natural Material (dirt, leaves, pollen, fatty substances, debris, pollen)
  • Chemicals (pool cleaning chemicals, chlorine, sun screen)
  • Hard-water Deposits (minerals found in hard water; also known as calcium scaling)

A couple of months back we shared a pool cleaning guide on our blog, head over to that piece for a more detailed description of the materials that cause deposits and stains around man-made water bodies.

Factors to Consider when Choosing Waterline Tile

1. Material Durability and Resistance

When selecting a waterline tile, it is essential to consider the durability and resistance of the materials. Pool environments can be harsh, with constant exposure to chemicals, UV rays, and varying temperatures. Opt for materials that are specifically designed for pool use and can withstand these conditions. Some popular choices include porcelain, glass, and natural stone tiles.

Since the main purpose of the waterline pool tile is to protect the sides or the pool and maintain hygiene it is essential that they are:

  • Non-porous/non-permeable
  • Thermal shock resistant
  • Frost proof
  • Chemical Resistant
  • Tested for outdoor and water submerged usage
  • Resistant to mildew, mold and bacteria (preferable)

2. Visual Appeal and Design

The waterline tile you choose should harmonize with the overall aesthetic of your pool. Consider the design theme, color palette, and architectural style of your surroundings. Whether you desire a modern, sleek look or a more rustic and natural ambiance, there are a plethora of options available to suit your preferences. Experiment with various tile patterns, colors, and textures to find the perfect fit for your pool.

3. Safety

When selecting waterline tiles, safety is paramount, with a primary concern being potential sharp edges, especially in cut tiles. Glass tiles offer the advantage of being softened or sanded, but this process can be trickier with porcelain. Emphasize a smooth, edge-free installation to minimize any risk of cuts.

Additionally, prioritize a quality, waterproof grout to protect against sharp edges. Proper grouting not only enhances aesthetics but also ensures safety by minimizing exposed edges. Regular inspections for cracks or wear, particularly in high-use areas, will contribute to maintaining a secure and visually appealing pool space.

4. Maintenance and Cleanliness

Waterline pool tiles ideally add durability to the swimming pool and are easy-to-clean. The most popular waterline tile materials that check all the characteristics listed above are ceramic, porcelain and glass. When paired with the right grout they will serve you for decades – maybe even a lifetime. Ceramic and porcelain tiles come in a wide variety of colors, sizes, finishes and textures. You can even mix and match some smaller ceramic tiles to create your own unique blend. While all three of the tile materials mentioned can be suitable for your swimming pool, we shall mainly be focusing on custom glass mosaic waterline tiles today – because that is where MEC’s expertise and passion lies.

5. Budget and Long-Term Investment

Budget considerations are an important aspect of any home improvement project. Determine your budget range for the waterline tile and explore options that align with your financial plan. Remember that the quality and durability of the tile should not be compromised, as investing in a high-quality product will save you money in the long run, reducing the need for frequent repairs or replacements.

Pattern & Color Options – Choosing the Design Theme for the Waterline Tile

You can choose from hundreds of ready-made tile designs and mosaic blends. There are so many options available in the market. Be sure to go with a brand you trust, you can also ask your tile dealer for technical specifications of the tiles you are considering. You could also get some samples to match the color with your space and aesthetic before finalizing one. Following are some amazing options in terms of color palette and design:

Natural or Neutral Colors & Textures

If you are mainly interested in the functional aspect of the waterline pool tile and do not want it to stand out separately – try a more neutral color. You could also go for something that matches the coping and desk and blends nicely into the swimming pool surrounding. Porcelain tiles that mimic the look of natural stone can be great as well. Another way you can incorporate a subtle waterline pool tile is to choose a blue or aqua glass mosaic waterline that matches the rest of the pool color and features.

Adding a Pop of Color to the Pool

Think of the pool waterline tile as an accent for your swimming pool wall. You  can take this opportunity to introduce a dash of color to it! Pick a color or a mix of complimentary colors that goes best with your personal taste and the design style of your backyard. Express yourself with brilliantly colored waterline tiles. Add an element of fun to your backyard oasis.

Waterline Tile Materials – Ceramic, Porcelain, Stone or Glass?

In the quest for the perfect waterline tile for your pool, the choice between ceramic, porcelain, stone, and glass involves a nuanced evaluation of various attributes.

Glass tiles, known for their versatility and visually stunning design options. While their customization and professional installation may incur a slightly higher cost, the benefits lie in low water absorption, easy cleaning, and resistance to stains. Before ordering glass mosaic water line pool tile ask the supplier if they are thermal shock resistant, UV resistant, and frost-proof. Occasional maintenance is recommended to preserve their aesthetic appeal. Pair them up with epoxy grout and you have a zero-porosity, hygienic, and highly durable solution for waterline pool tile.

On the durability front, porcelain tiles emerge as high performers, coupled with resistance to water absorption. Though design options may be more limited compared to glass, their moderate cost and low-maintenance nature contribute to their practical appeal. The only potential hurdle comes during installation due to their heavier weight.

For those seeking an enduring and natural aesthetic, stone tiles beckon with their timeless appeal. However, the variable cost and maintenance considerations, including periodic sealing, should be weighed carefully. Notably, unsealed stone may absorb water, potentially housing microbes, bacteria, and mold, necessitating specific cleaning methods based on the chosen stone type.

On the cost-effective end, ceramic tiles bring forth an extensive array of designs, balanced with a moderate level of durability. Despite being susceptible to chipping, their easy installation and maintenance, along with moderate water absorption, make them a popular choice. Cleaning is straightforward, requiring only a mild detergent. However, ceramic tile colors might fade over time from long periods of exposure to sun’s UV rays.
