Installation Instructions

  1. Tub or shower unit should be on the job site during the early stage of framing. Studs may be temporarily omitted to allow unit to be moved into place.
  2. Rough-in drains should be located according to the line drawings for that particular unit. When measuring the tub or shower unit to obtain these measurements, be sure to use the top of the unit for the overall depth and width of the unit. Please note that most units have slanted backs and sides, but the front of the unit should always be installed vertically plumb.
  3. Prior to installation, check to be sure the framed-in area is proper size, square, and plumb.
  4. If a one hour fire wall is required, contact the factory for recommended method of installation. A one hour fire wall can normally be obtained by placing 5/8" dry wall on the studs prior to the installation of the unit.
  5. A code approved drain outlet should be used. Be sure to use silicone or plumber's putty between the chrome flange and the finished side of the tub/shower.
  6. On the back of the unit, lay out accurately the location of the holes for supply and mixing valves. Shower head may be located either through wall of unit or in wall above. From the back of the unit, drill a pilot hole (1/4" or less) at location markings for fittings (Figure 2). From the face of the unit, drill or cut these holes to required size. Use a hole saw of the proper size (Figure 3). For shower units, move the unit into framed area by tipping the unit toward the installer and push until the waste pipe is directly under the drain outlet, then tip the shower upright into the framed area.
  7. After unit is positioned into framed area, check level of shower or tub/shower and be sure apron is down tight to the floor.
  8. Spot secure the flanges, top and bottom, while continuously checking to see that the unit is level and that the side walls are plumb.
  9. Using No. 8 screws, fasten the top flanges to each stud and then fasten the side flanges approximately 8" on center.
  10. Install plumbing hardware in keeping with good plumbing practice and in compliance to local code requirements.
  11. If a dry wall finish is to be used, place dry wall over fastening flange, screw dry wall and tub flange into studs, mud tape and finish. If plaster is used, screw lath over fastening flange and finish plaster to bead (Figure 4).
  12. Towel bars and special grab bars may be bolted or screwed into the tub unit, with the use of a wood strip or block on the back side of the unit prior to installation. Care should be taken when installing grab bars so that all applicable codes and requirements are followed.
  13. Upon finishing construction, the unit can be cleaned with warm water and detergents. Roofing tar and paints can be easily removed without damage to the unit by the use of turpentine, paint thinner, or acetone.
