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.
Does it get slippery if it becomes too wet?
No - it’s made from pressed diatomaceous earth. It absorbs water instantly and it dries up fully in a matter of minutes. It’s really quite miraculous.
