Hi- we are going to lay self laying sheet vinyl over an old tile floor in our bathroom, 5x6ft. We keep hearing that you'll see the underlying tile pattern. Is that going to be an issue with such a small area? The vanity will cover 2x2.5 of the area. If so any recommendations on how to fill in the grout lines?

We were also thinking of using the self adhesive vinyl tiles but are concerned they won't stick to the smooth tiles-if you have any experience with that it would be helpful too as that would be by far the easiest way for us to go.

Thanks!!
