To remind us it someday will be a reality, we picked the tile in December, and here it sits on our existing patio. Much as we have enjoyed the cement patio with tile accents, it's difficult to keep clean, and we're replacing it with this blue tile .... soon, we hope! Each blue tile is 50cm by 50cm. We chose the blue tile carefully. It's rough surface will make it less slippery when wet, and it's double-thickness makes it durable enough for the driveway and parking area.
