The Bobrick B-4390 Stainless Steel Recessed Heavy-Duty Soap Dish and Bar is intended for installation in showers and sink areas with stud walls that feature rough openings that are 6 inches in width by 4 inches in height by 4 inches in depth. Crafted from 19-gauge, type-304 stainless steel, the shell and flange are outfitted with two countersunk holes for mounting. The body of the unit is free of seams, thanks to its drawn, one-piece construction. A retaining lip is included in the design to prevent the soap from falling onto the floor of the shower or into the sink. This lip is fabricated from 18-gauge, type-304 stainless steel. To finish the design, a heavy-duty bar made of type-304 stainless steel that is 3/16 of an inch thick runs across the top of the soap dish. The matte polished finish featured in the soap dish has an attractive gleam that will enhance the decor of your commercial restroom.
