I’ve used a towel style bath mat for decades, I think it’s the most hygenic. It goes on the floor to shower, then gets hung to dry between showers.
I lay floors and hadn’t seen a “permanent” bath mat in years but ran into one today. It was that typical shag rug style, bright pink. This was a clean house but it was strange to me, I didn’t think anyone used those anymore.
We have those bathmats that are just mats without a rubber backing. The rubber backed ones tend to get really ratty and messed up in a dryer.
The pure cloth ones tend to last longer, imo. And they don’t make your clothes smell like rubber. White ones work best, as they can be bleached as needed.
