Abstract: An injection molded shower stall assembly or bathtub assembly particularly for use in a recreational vehicle includes an injection molded tub or shower base, which includes an integrally formed drainpipe which is externally threaded and adapted to easily and permanently be connected to plumbing for the recreational vehicle. Injection molded walls are formed to surround either the shower stall or tub. The injection molded walls have lower edges that interfit with edges of the tub or shower stall in a way which prevents water from flowing behind the preformed walls and holds the lower edges of the preformed walls in position, eliminating the need for any type of penetrating fastener along the base of the walls. The walls are formed in multiple sections that fit one on top of the other, with interfitting lower and upper edges, again to reduce the need for penetrating fasteners and to hold the sections in position.

Abstract: A custom shutter includes a central body portion and first and second end caps. The central body portion includes two stiles and a central portion all of which are formed integrally as one piece. The top and bottom end caps include first and second legs and a central connecting body portion. The legs are designed to be inserted within the hollow interior of the stiles with the top edges of the stiles resting against the stepped portions of said end cap and wherein an inner surface of said end cap covers any exposed edge of the central portion of the shutter body.
