The floor is not slippery, we are mature people with balance issues, wow one of the best mats I have ever used, after a shower it sets well, absorbent of shampoo / soap / personal care products. Without staining, I personally thought the large would be to large for the inside of the shower, believing I had to put it on the outside, no, perfect size for inside the shower on slippery tiles, MAGIC, oh yeah 👍 that is why it is called magic ✨✨✨✨✨
