One of the best features of ceramic tile is the variety of shapes, colors, and finishes available. This truly unique shower is a great example of just what we mean. The subway tiles in earthy tones is the backbone of the shower, with much smaller rectangle tiles in greenish blue on the ceiling. The window is the detail that makes this shower a standout, though. The porthole-like window, secured with sturdy cast iron, is encircled with rings of opalescent mosaic tile in blues, purples, yellows, and greens that give you the fantastical feeling of being under the sea. Your imagination is the limit with all the possibilities that ceramic tile offers.
