A different angle you could look at is non abrasive anti slip, this page I was looking at earlier explains about how non abrasive anti slip is perfect is showers and baths. it is also very easy to clean as the material is water proof and has a pvc layer, so dirt doesn't stick.

Hope this helps

My showering mat has little sticker pads all over the bottom, very safe to stand on.

I am not sure what quality is a great showering mat because i bought plastic mat and i slip/fall but they claimed non slip. it is silly. some ppl say that mat with "grass look like" is better but how do i go around that? can you post any mat that you think is gtrat from slip because i use conditioner , bath gel, etc.

please share yo personal experience too. tell me why plastic vs rubber vs "grass-looking like"

thanks
