Before Starting
Consult your local building codes with questions on installation compliance
standards. Building and plumbing codes may vary by location, and FlexStone Bath
Systems is not responsible for code compliance standards for your project.
1. The FlexStone wall system is designed to be installed over a solid substrate such as green board,
cement board, or other water resistant backers. Substrate should be clean, dry, and free of dust
or loose paint. Unless using our Remodel Trim Kit, any existing surround material should be
removed.
2. The Remodel Trim Kit (sold separately) allows FlexStone to be used over existing tile. Tile should
be in good shape, and wall surfaces should be flat (i.e. remove any accessories that would
interfere with the FlexStone panels.) The 4 pieces of 96” length would replace Items C, D, E, F,
and G. Follow instructions included with Remodel Trim Kit.
3. If installing a new bathtub or shower base prior to FlexStone installation, follow the
manufacturer’s instructions, and install the tub or base level and square to walls.
4. Turn off the water supply and complete any plumbing modifications prior to installing your
FlexStone surround. Leave plumbing handles off until surround is installed. Plan the placement
of the shower head such that it is either above the height of the wall panels or at least 2” below
the top of the wall panels. This will keep the trim moldings from interfering with the pipe and
escutcheon plate.
5. Review Section 7 and decide how the vertical trim moldings will be installed, either outside the
shower base, or on top of the base threshold. This will impact the width of the side wall panels
in Section 3.
