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.
Glad that you asked! I weave rag rugs from dead clothing and sheets. It goes Sheet > Rag for spills > Cleaning rag > Teared into strips for weaving. When I have a full bag, I weave a new rug, having fun with the colors on hand. I get 60cm*1m absorbent rugs for the bathroom or the mudroom. Some are so cute my kid preempts them for her bedroom. They’re resistant, thick, easy to wash, easy to discard when they get ratty.
