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.
I remember reading something a while ago that said the rubber backed mats should never go in the dryer, and while I forget the exact reason, it wasn’t just because the dryer damages the mat. Searching online, it looks like the rubber can also damage the dryer and poses an increased fire risk.
