Abstract
A pre-fabricated shower pan provides the features of a custom on-site constructed shower pan. The pre-fabricated shower pan comprises a wood frame, a drain, a sloped floor, and a hot-mopped tar covering. A box is constructed from a four by six dam on one or two sides, one by six lumber on the remaining sides, and a plywood floor. A drain is mounted in the center of the plywood floor. The sloped floor is created by layers of composition shingles or similar material. Tar is mopped over the shingles and on the inside of the box to provide a watertight seal. The tar may further be mopped over part or all of the outside of the box.
Description
- The present invention relates to shower construction and in particular to a pre-fabricated shower pan.
- Many homes, offices, and businesses include bathrooms or restrooms with showers. While pre-fabricated single piece shower liners are available, many prefer a more custom built tile shower interior. Generally, such custom shower interiors are built by first framing the shower, then building a shower pan in the base of the shower, and then completing the shower. The step of building the shower pan includes constructing an enclosed base, laying a felt-like material inside the enclosed base, and mopping hot tar over the felt. The sloped floor may be formed later using concrete, and tile is laid over the concrete. While very good results are provided by these steps, the method is tedious and unpleasant. The tar is heated to over 400 degrees Fahrenheit for mopping and produces fumes and heat, generally in an enclosed working area.
- The present invention addresses the above and other needs by providing a pre-fabricated shower pan which provides the features of a custom on-site constructed shower pan. The pre-fabricated shower pan comprises a wood frame, a drain, a sloped floor, and a tar covering. A box is constructed comprising a four by six dam on one or two sides, one by six lumber on the remaining sides, and a plywood floor. A drain is mounted in the center of the plywood floor. The sloped floor is created by layers of composition shingles or similar material. Tar is mopped over the shingles and on the inside of the box to provide a watertight seal. The tar may further be mopped over part or all of the outside surface of the box.
- In accordance with one aspect of the invention, there is provided a prefabricated shower pan. The shower pan includes a box having a plywood floor, at least one solid wood dam attached to the floor, at least one solid wood side wall attached to the floor, and a solid wood rear wall attached to the floor. A shower pan interior defined by a top surface of the floor and inside surfaces of the walls and the dam. A drain is attached to the floor approximately centered on the floor. Composite roofing or similar material is laid on the floor creating a slope from the dam and walls downward to the drain and composite shingle material over the material. Hot mopped tar is applied over the composite shingle material to provide a water tight surface
- In accordance with another aspect of the invention, there is provided a method for constructing a pre-fabricated shower pan. The method comprises providing a floor, cutting a drain hole in the floor, attaching a dam to a front edge of the floor, side walls to the dam and to side edges of the floor, and a rear wall to the side walls and to a rear edge of the floor. A drain is attached to the floor, residing in the drain hole. A sloped layer of a filler material is laid on the floor between the dam and walls and the drain to create a sloped floor sloping downward towards the drain. The interior surfaces on the floor, dam, and walls are hot mopped with tar.
- The above and other aspects, features and advantages of the present invention will be more apparent from the following more particular description thereof, presented in conjunction with the following drawings wherein:
