Key Specifications

• Dimensions: Typically, 244 mm x 119 mm.

• Thickness: Generally, 9 mm is the standard for this format.

• Material: Usually porcelain stoneware or high-density ceramic, chosen for its low water absorption rate (typically $<0.5\%$), which ensures durability against submersion.

• Surface Finishes:

  • Semi-Gloss/Smooth: Primarily used for the interior pool walls and floor.

  • Antiskid ('C' Finish): Essential for pool edges, steps, and surrounding deck areas. These often meet high slip-resistance standards (such as Class C under DIN 51097) to prevent accidents in wet conditions.

Essential Characteristics

• Chemical Resistance: Highly resistant to pool sanitizing chemicals (chlorine, ozone, etc.) and aggressive cleaning agents.

• Durability: High resistance to wear, frost, and extreme temperature fluctuations, which is critical for both indoor and outdoor installations.

• Hygiene: The non-porous nature of these materials makes them resistant to mold, bacteria, and algae buildup.

• System Components: This size is often part of a "complete system" that includes matching specialized pieces such as:

  • Fingergrip tiles: For safety along the waterline/gutter.

  • Radial/Cove tiles: For internal and external corners to facilitate easier cleaning and prevent debris accumulation.

  • Nosing pieces: Specifically designed for pool edge finishes.
