Mosaic tiles are found in many different sizes, materials, colors and textures.
In this NYC bathroom, the mosaic used here is a beautiful ocean hued matte stone finish. What impressed me was the notion to keep it SIMPLE, people!

When designing a smaller space, try to keep the color palette monochromatic or use colors that harmonize well together, as pictured. The blues, greens, greys and whites of this tile, installed floor-to-ceiling, create a calm guest bathroom that is timeless.
