It looks like you're describing a bath shower mat with non-slip features. These mats are designed to provide a safer and more comfortable showering experience by preventing slips and falls in the bathroom. Here's a breakdown of the features you mentioned:

Material: PVC (Polyvinyl Chloride) is commonly used for bath mats due to its durability and resistance to moisture. It's a popular choice for bathroom accessories because it can withstand water and is easy to clean.

Non-Slip: The primary function of this mat is to prevent slipping. It likely has a textured surface or some form of pattern that provides traction for your feet while in the shower or bathtub.

Rubber: Some bath mats have a rubberized backing or additional rubberized features to enhance grip on wet surfaces. Rubber is known for its non-slip properties.

Anti-Slip Suction: Suction cups or suction-like features on the bottom of the mat help it adhere securely to the bathtub or shower floor. This prevents the mat from shifting or sliding around when you step on it.

Size: The dimensions you mentioned (75cm x 34cm) indicate the size of the mat. It's important to choose a size that fits comfortably in your shower or bathtub space.

When using a bath shower mat like this, make sure to clean it regularly to prevent mold or mildew buildup, as bathrooms can be humid environments. Additionally, always place the mat on a clean, dry surface for the best anti-slip performance.
