Ensure that the floor and stud walls are square and plumb on a
level floor as shown in Figure A. Provide a 5" x 5" (127 x127mm)
opening in the floor for the drain and refer to the product rough-in
for actual drain location. Draw a line 3-1/2" (89mm) [model
A8003L-LHO/A8003L-RHO draw a line 4" (102mm)] above the
level subfloor on the wall studs at each side of the opening.

All of the shower bases require purchasing a round shower strainer type
drain for use with a standard 2" (51mm) plastic schedule 40 waste pipe.
Figure B shows the typical drain assembly. Before installing drain into
the shower base, remove strainer (Fig B). This will be installed after
shower base is in its final position. Cut the waste pipe height so that the
drain body will fit snug in the shower base. Apply silicone sealant
between the drain body and shower base.

NOTE: Drain not included and must be purchased separately.

After the bedding material has been poured and before it sets,

lower the shower base into position with the drain assembly sliding
over the waste pipe (Fig. C). It will be necessary to "rock" the shower
base until the top of the tile flange aligns with the lines drawn on the
stud walls from Step 1. Make sure the apron is contacting the rough
floor along the entire length of the shower base and ensure that the
base is level in two directions as shown in Figure D.

and prevent construction debris from entering the drain. Finish
the shower base installation. Any finish material such as tile or
wallboard must be self-supporting if it contacts the deck of the
shower base as shown in Figure E.

Install the water resistant drywall while keeping approximately
1/4" (6mm) to 1/2" (13mm) of clearance between the shower
base and drywall to prevent any possible water from wicking.

POST INSTALLATION CLEAN-UP

Remove all construction debris. Tile grout can be removed with a wooden popsicle stick or tongue depressor. Do not use wire brushes or any other
metal implement on surface.

Post installation clean-up generally can be completed using warm water and liquid dishwashing detergent. Stubborn dirt or stains may be removed
using granular Spic and Span® mixed with water.

Painter's naphtha can be used to remove excess adhesives and/or wet oil-base paint.

AFTERCARE and CLEANING

!

WARNING:

• Excessively hot water may cause surface damage.

• HARSH CHEMICALS SHOULD NEVER BE USED ON SHOWER BASE SURFACE. Clean after use with a mild liquid household detergent cleaner.
Do not use Lestoil, Lysol Disinfectant (spray or concentrate), or Lysol Basin, Tub and Tile Cleaner, Windex, Mr. Clean, Dow Disinfectant Bathroom
Cleaner, or cleaning products in aerosol cans.

• Do not use wire brushes, knives or sharp objects to remove stains, cigarette tar deposits, or other surface blemishes.

• Abrasive cleaners or powders must not be used, since they will dull the surface. If the glossy surface loses its sheen, dulled areas or light scratches
can be restored by rubbing with a white "automotive type" polishing compound and waxing with a "liquid wax."

• Do not wax areas where you walk or stand.

• Do not allow nail polish remover, acetone, dry cleaning fluid, paint remover or other solvents to come into contact with the surface.

• Clean the surrounding surface immediately after using caustic drain cleaners.

• Burning cigarettes will damage the surface.

• Should damage to the fixture occur, repairs can be made quickly and easily.

Your distributor or builder can provide details.
