Recessed U-Channel for Glass Shower by A Cut Above Glass | Jun 24, 2015 | News Recessed U-Channel for Glass Shower This U-Channel is the ideal selection for recessing into the floor, wall, or ceiling, to provide the frameless “all-glass” appearance. The top lip of the U-Channel is angled to deflect the water away. A lip on the top of the U-Channel covers the edge of the tile. Glass is wet glazed into Channel. 98 inch (2.49 meter) stock lengths are available for 3/8″ or 1/2″ (10 or 12 mm), in a choice of brite anodized and brushed nickel finishes. Coordination with your tile setter will be imperative as the tolerance between tile has to be pre thought out. We have installed glass in between tile for years, and I think using this U channel will give an outstanding finished shower look.
