If a mortar cement bed was not installed, align the drain hole in the felt pad with the drain hole in
the subfloor. Secure the felt pad into place with fasteners (such as staples or nails).
Install the drain and overflow assembly to the bath according to the drain manufacturer's
instructions.
Dry fit the bath.
Verify that the bath is level. If the subfloor is not level, insert shims under the bath to adjust for
level.
Mark the height of the bath flange on each stud wall. Set the bath aside.
Measure and mark 1-9/16" (40 mm) down from the first mark.
Cut two ledger strips from 1x4 material to the length specified in dimension "G." Cut a third ledger
strip to fit the remaining width of the stud pocket.
Install the ledger strips.
Dry fit the bath again to make sure the bath is not being supported by the rim. If needed, remove
the ledger strips, slightly lower them, then reinstall.
Remove the bath.
