Penny tiles always seem to add an extra bit of "wow" to any design project. The size and shape give texture and add visual interest to a space. When used to tile an entire bathroom, the effect is absolutely stunning. Because they are installed in 12" x 12" sheets, they sometimes create an unintentional pattern of squares which can be a little off-putting. However, having the tiles installed on a mesh matte allow for easier installation and is beneficial when wrapping corners and crevices. What are your thoughts on penny tiles? Have you had any installation issues?
