Basco Shower Door Co. has added three new glass patterns to its line of Celesta luxury glass enclosures. Cobblestone is reminiscent of the stone roads and walkways of historic towns such as Colonial Williamsburg and Charleston. Arctic Frost offers an obscure glass pattern similar to a frosted windowpane on a cold winter morning. Venetian is a vertical glass pattern that surrounds the bather with soft light. The company now offers six different glass styles, each available in 1/2-inch and 3/8-inch thickness.
