WATERLINE TILES
Handcrafted glazed tile designed to bring lasting color and character to the pool waterline. Made from natural clay, each tile carries subtle variation that gives the finished installation depth, movement, and a distinctly handmade feel.
Each tile is individually made, resulting in natural variation in color, tone, size, flatness, texture, and glaze coverage. Differences may be noticeable from piece to piece and within the same batch, creating the layered character of authentic handmade tile.
Natural surface marks, irregular edges, minor chips, pinholes, and subtle glaze irregularities may also occur. These characteristics are expected and are not considered defects.
For the most balanced installation, blend tiles from multiple boxes before installation.
The beauty of glazed waterline tile comes from the relationship between natural clay, glaze, and kiln firing. Subtle differences in glaze depth, sheen, pooling, and color are expected, particularly around handmade edges and surface irregularities.
Depending on the glaze, crazing may also naturally occur as fine hairline lines within the glazed surface. These characteristics contribute to the depth and individuality of the finished installation rather than creating a perfectly uniform appearance.
Our waterline tiles are selected for use in pool environments, where the kiln-fired glazed surface provides a durable, easy-to-maintain finish designed for regular exposure to pool water.
Proper installation, setting materials, grout, and ongoing water chemistry are essential to long-term performance. Always follow our pool installation recommendations and consult a qualified pool tile professional for your specific project.

FAQ
Yes. Our Pool Waterline tiles are made from a specialty dense clay body, high-fired at 1200°C and finished with a durable ceramic glaze.
POOL WATERLINE APPROVED
Our Pool Waterline tile body has been independently lab-tested under ASTM C373 / ANSI A137.1, with an average water absorption of 0.68%.
This places the tile within the Vitreous category:
- Impervious: ≤ 0.5%
- Vitreous: Our tile at 0.68%: 0.5%–3.0%
- Semi-Vitreous / Non-Vitreous: > 3.0%
This rating makes our tile suitable for chlorinated and saltwater pool waterline applications when properly sealed and installed.
Proper sealing, waterproofing, and installation are essential for long-term performance.
Pool Waterline tile uses a specialty dense clay body that is high-fired for significantly lower water absorption than our standard clay tile.
Our Pool Waterline body has an average tested water absorption of 0.68%, placing it within the vitreous category and making it suitable for pool waterline applications when properly sealed and installed.
Standard clay tile is more absorbent and is not recommended for pool waterline applications.
No. Pool Waterline tiles are designed and tested specifically for the pool waterline, where the tile experiences both water and above-water exposure.
They are not recommended for continuously submerged applications such as pool floors, steps, benches, or full pool interiors.
For fully submerged installations, we recommend a tile specifically rated for continuous submersion.
Yes. Pool Waterline tiles are rated for use in saltwater pools when properly installed.
Yes, Pool Waterline tiles can be used at the waterline of spas and hot tubs. They are not intended for fully submerged spa or hot tub applications.
Yes, for fountain waterline or splash-zone applications.
For continuously submerged fountain surfaces, we recommend a tile specifically rated for full submersion.
As with pool installations, proper sealing, waterproofing, setting materials, and professional installation are important for long-term performance.
Yes. Pool Waterline tiles can also be used above the waterline for pool surrounds, raised walls, fountains, and other decorative applications.
Yes. Before installation, we recommend sealing each tile with a penetrating sealer, ideally, Clay Imports Penetrating Sealer. For best results:
- Dip each tile into the sealer for 2 seconds (making sure that the entire surface is adequately coated)
- Wipe away excess from the glazed surface with a clean, lint-free cloth
- Let the tiles dry face-up on a stable, flat surface for at least 1 hour minimum
This drying period is crucial as it ensures that the sealer penetrates the tile effectively, providing the best possible protection.
No. Pool Waterline tiles are not freeze-proof and are not recommended for exterior installations in freeze-thaw climates.
For projects where occasional freezing may occur, proper waterproofing, drainage, expansion joints, and professional installation are especially important. Review our installation guide before specifying the tile for your project..
When properly installed, Pool Waterline tiles are designed for long-term use at the waterline. Proper substrate preparation, waterproofing, setting materials, and installation are essential to help prevent cracking.
Minor crazing, fine surface lines within the glaze, may develop over time. This is an aesthetic characteristic of glazed clay tile and is different from structural cracking.
Clean regularly with a pH-neutral cleaner and a soft cloth, sponge, or brush. Avoid harsh chemicals or abrasive cleaners that may damage the tile surface. Routine cleaning will help prevent buildup along the waterline and keep the tile looking its best.
With proper installation and maintenance, Pool Waterline tile is designed for long-term use.
Regular cleaning, periodic inspection, and resealing as needed help maintain the tile and installation over time.
Clay Imports provides installation guidelines, but we do not warranty installation workmanship or outcomes.
Because installation conditions vary by project, we recommend working with a qualified pool tile professional and reviewing our installation guide before beginning.
Always inspect your tile upon delivery and contact us promptly if anything appears incorrect.
