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.
My wife and I shower together, someone is getting out sopping wet because either the other one is still going or there’s just not enough room to both dry in the shower. Heated floor dries the bath mat just as well as the towel rail anyway
