When choosing marble bathroom floor tiles, it is often most practical to choose a type of marble or limestone with a water absorption rate below 0.5% and anti-slip properties, such as a rough-textured limestone or grooved marble. Commonly used dimensions are 300 × 300 mm or 600 × 600 mm, with a 2-3 mm gap filled with mildew-proof volumetric grout to allow water vapor discharge. To avoid cracking of stone due to temperature differences, it is recommended to implement a heating system (maintaining a floor temperature of 40℃ or lower) in the bathroom.
