Instructions / Assembly
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. If required by local code, use a competent and licensed plumber for 
all plumbing installation. 
1.  Be sure to read these installation instructions carefully before starting to install the 
FlexStone Shower Base. 
2.  Before  installing  your  FlexStone  Shower  Base, check  all  boxes  and  packaging  for 
shipping damage. If unit has been damaged during shipping or has a defect, please 
contact FlexStone Customer Support immediately at 1-877-941-3662. 
3.  Be sure that the installation surface is flat, level and solid and will be able to support 
the total weight of the  shower base. Also, make sure that all framing around the 
base is square. Please note that irregular installation surface level or improper angle 
of side walls will result in serious problems for your installation. 
4.  This shower base does not include a drain assembly. The drain opening is 3 ¼” in 
diameter and accepts a standard 2” compression fitted “receptor base” drain.
