The SL Gray 6×6 Pool Tile Series is a purpose-engineered aquatic tile designed for both beauty and extreme durability in permanently wet and submerged environments. Its cool, neutral gray tone brings a polished, contemporary character to pools, spas, water walls, and fountain basins of any scale.

Each 6×6 tile features a smooth, low-variation surface with a semi-gloss or glazed finish that enhances water reflection and resists staining from pool chemicals, algae, and mineral deposits. The square format installs quickly in a straight-set pattern with consistent grout joints, making it practical for large pool projects without sacrificing design refinement.

SL Gray is ideal for pool waterline tile bands, submerged pool floors, spa interiors, and outdoor fountain surfaces — and is rated for freeze-thaw climates when properly installed. Because pool tile must be ordered in complete lot quantities to ensure color consistency, we strongly recommend requesting a sample and calculating full project quantities before ordering.

Free Shipping: This product ships at standard freight rates calculated at checkout based on your location and order size.

Processing & Delivery: Orders are processed within 2–3 business days. Large orders ship via LTL freight — curbside delivery only. An adult must be present to sign for delivery. Estimated transit: 2–10 business days after shipment.

30-Day Returns: Uninstalled tile may be returned within 30 days of delivery. Inspect all tile carefully before installation — installed tile cannot be returned or exchanged. Samples are final sale.

Exclusions: Free shipping does not apply to Hawaii, Alaska, U.S. territories, or international addresses. Additional charges may apply for remote delivery areas.

Sealing: Porcelain pool tile is inherently low-porosity and does not require sealing under normal circumstances. If grout joints are used in submerged areas, use a pool-rated epoxy grout rather than traditional cement grout — epoxy grout requires no sealing and resists chemicals and algae growth.

Cleaning: Clean with a pH-neutral tile cleaner or a diluted pool-safe tile cleaner. Avoid acid-based cleaners (including vinegar or muriatic acid at full strength) which can dull the glaze and damage grout over time. For calcium or mineral deposits at the waterline, use a non-abrasive calcium remover formulated for pool tile surfaces.

Installation: Use a white polymer-modified thinset rated for wet and submerged applications — verify the thinset is pool-rated and meets ANSI A118.4 or equivalent. For waterline applications, back-butter each tile and press firmly to eliminate air pockets. Use epoxy grout for submerged joints; standard sanded grout is acceptable for above-waterline areas. Allow full cure time before filling the pool.

Important: Inspect all tile before installation. Variations in color, veining, and texture between pieces are natural characteristics of genuine stone — not defects. Order 10% overage for cuts, waste, and future repairs. Tile & Mosaic Depot specialists are available M–F 8:30AM–5PM PST at 855-797-8453.

Product & Installation Guidance

Natural stone is a product of the earth — every piece is one of a kind. A little planning ensures your finished installation looks its best and lasts for decades.

Natural Variation
Color, veining, texture, shade, movement, finish, and sizing vary from piece to piece. Product photos and samples are a general reference and may not match the exact material you receive. These variations are inherent characteristics of natural stone — they are part of its beauty, not defects.

Before You Install

  • Order roughly 10% extra to allow for cuts, waste, and future repairs.
  • Blend tiles from multiple boxes as you work to achieve the most natural, balanced appearance.
  • Dry-lay and inspect the full layout before setting a single tile.
  • Installation constitutes full acceptance of the product, so review everything carefully first.

Sealing & Care
Natural stone should be sealed with a quality penetrating sealer before and after installation, and re-sealed periodically in wet or high-traffic areas. Clean only with a pH-neutral stone cleaner; avoid acidic products, bleach, vinegar, and ammonia, which can permanently etch the surface. Outdoor installations may weather or change tone over time with exposure.

Responsibility
Tile & Mosaic Depot is not responsible for improper installation, labor costs, substrate conditions, product misuse, or damage from improper handling, sealing, maintenance, or harsh chemicals. No claims, returns, or replacements can be accepted on installed material.

California Proposition 65: Some natural stone products contain substances known to the State of California to cause cancer or reproductive harm. For more information, visit www.P65Warnings.ca.gov.

Order a Sample First

Seeing real stone in your own space — under your own light, beside your own finishes — is the best way to buy with confidence. We make it easy and affordable.

How It Works
Samples are just $7.99 each with free shipping, and they ship in 1–3 business days. Sizes vary by material and availability, typically ranging from 3"×3" up to 8"×8". Exact dimensions aren't guaranteed, but every sample is cut from the same material you'll receive in a full order.

What a Sample Shows
Samples help you evaluate the general color, texture, finish, and overall character of a product before committing to a full order. Because natural stone varies from piece to piece, your sample is representative — it may not capture the complete range of variation across an entire lot. For current lot photos, just ask our team.

Good to Know

  • Samples are final sale — non-returnable and non-refundable.
  • Ordering a sample before a full purchase is always recommended, especially for natural stone.
  • Planning a larger or custom quantity? Contact us for a tailored quote.
