White Subway Tile Shower with Black Accent Border in Manchester Square
About This Project
This Manchester Square bungalow bathroom received a full shower conversion — the existing tub-shower combo was removed and replaced with a walk-in shower. The homeowner chose 4x8-inch white subway tile for the walls with two horizontal rows of matte black 1x4 accent tile running across all three shower walls at shoulder height. The black accent rows required precise layout planning: we snapped a level line at the correct height on all three walls simultaneously so the bands align at the corners without any visible step.
Before any tile went up, cement board was installed over the framed shower walls and Schluter Kerdi waterproofing membrane was applied to the full interior surface. The shower floor used 2x2-inch white mosaic tile set on a pre-sloped mortar bed. The black-framed glass enclosure, installed after the tile work was complete, matches the black accent tile in the wall pattern.
