Often one corner of a shower is the key starting point. You can see how the designer of this tile layout started with half tiles in the corner, then worked out from there. At the entry to the shower, the eye is drawn to this corner with the bench, making the corner itself the shower's feature wall. Tip: Not every shower needs a feature wall, but in most showers one wall or one corner is the primary viewpoint. Take care to ensure this main focal point does not look unbalanced.
