The David Hockney 1978 art piece Swimming Pool with Reflection inspired this California-cool bathroom. Watery-blue glass mosaic tile spills down the shower wall and out onto the concrete-gray tile floor in puddles. The custom back-painted glass vanity floats on the blue walls and is anchored by a chrome Kohler faucet, adding a modern sophistication to this fun space perfect for a young boy.
