Pvc Hygienic Material: Anti slip bath mat made of PVC and feels more secure and stable in shower. Strongly Adhesive: Pebble bath mat with 200 SUCTION CUPS sticks securely to the bottom of the tub, that help hold in place on smooth, clean surfaces and will not shift down towards the drain. Custom Cutting: Its width and length are 16" and 35". You can cut easily the bath mat to any shape, but carefully decide on the end-look ahead of time. Draining Design: There are spaces between the ‘faux rocks’ that allow center drain to manage, and it is also fine to cut bigger holes to drain. Easy to Clean: Just washing with some towels and then placing in the shower or tub after the spin cycle is okay, not need machine to wash.
