4. Install the Plumbing
NOTE: Provide access to all plumbing connections to simplify future maintenance.
Locate rough plumbing for the drain according to the correct model's roughing-in dimensions.
Position the plumbing according to the roughing-in information. Cap the supplies and check for
leaks.
Install a 2" (5cm) drain pipe to extend 3/8" (1cm) above the subfloor or slab. A pocket is required in
a slab construction to accommodate the drain fitting.
If possible, provide an access at the back of the plumbing wall for servicing the supply and waste
piping.
Install the shower valving according to the manufacturer's instructions. Do not install the trim at
this time.
