Available in four styles-square, narrow combo, soap and wide combo, the niches’ overall design protects them from leaking, rotting or degrading. In addition to shower and bathroom applications, Bonsal niches can also be used as recessed shelving, providing a decorative look. Circle 170 on the Reader Inquiry Card.
