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.
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.
