Hello - I am putting in a ceramic tile floor in a bathroom and plan on cutting the tiles and using them for a baseboard. Is there a correct size that this baseboard should be? And should I put anything on the top edge of the tile to finish it off? Any information would be appreciated. Thanks!

What I remember seeing is tile with a finished, rounded edge or sort of a tile quarter round to finish it. As for the height, I would go with something easy that appeal to your eye. Maybe at least 4'' high to protect the base of the wall.
