I'm planning to use WZ Otto 3x6 tiles in matte white for a fireplace surround, floor to ceiling, in a modern, white apartment. Since we need 50sf plus 25 linear feet of trim, I'd love to find a less costly alternative. A little visual interest but subtle. Something readily available as we'll be ready for tile in 3-4 weeks. Also, has anyone used WZ tile with Schluter strips, if I want to eliminate the trim pieces?
