My shower is original to our house and the bottom of the tub is very slippery having been made before they put safety footing on the bottom so we need shower mats. I tried several safety mats in the last few years but none of them hold up well. They always slip while getting in and out of the tub. When I saw this one on Wayfair I decided to take a chance. So far so good- no slippage and the mat itself is thick and sturdy.
