Common anti-slip features for shower tray mats include: textured slip-resistant surfaces, non-skid backing or feet, suction cups or suction arrays for secure attachment to smooth surfaces, and molded grips or raised patterns to improve footing.
Shower tray mats typically manage moisture in two ways: hard absorbent tiles (like diatomaceous earth) soak up standing water and air-dry quickly, while softer plastic, rubber, or vinyl mats rely on perforations or drain holes so water drains away to reduce pooling and mildew.
There are two main types: hard-surface mats (e.g., diatomaceous earth tiles) that are firm and quick-drying, and soft, cushioned mats (foam, rubber, TPR) that prioritize padding and comfort. Each type balances comfort, drying speed, and slip resistance differently.
Interlocking tiles connect edge-to-edge so you can build a custom-sized mat. They typically have grip backing or textured undersides for stability and simply snap or slot together to cover a larger area while remaining easy to add, remove, or reconfigure.
Sizes vary from small interlocking tiles (about 9.8 × 9.8 inches) up to larger rectangular mats roughly 28–36 inches long by about 13–17 inches wide. Many listings fall in the mid-20 to mid-30 inch length range.
Suction-style mats are intended for smooth, even tub or shower surfaces and are not recommended for textured or uneven surfaces. Product directions often advise cleaning the surface and wetting the mat base before placing it to improve suction.
