2. Install the Bath

CAUTION: Risk of property damage. Make sure the factory-installed drain connections have not
become loose during shipping. Tighten as needed to prevent leakage.

CAUTION: Risk of personal injury. This bath is extremely heavy. Obtain sufficient help and use
lifting straps to carefully lift or move the bath.

Stack together two 6’ (1.8 m) lengths of 2x4 lumber. Secure each set of stacked 2x4’s together with
nails or screws.

Position the stacked 2x4’s on each side of the drain pipe to temporarily support the bath.

With help, use lifting straps to carefully lift the bath into position on the 2x4’s so the bath drain is
over the drain pipe.

Carefully reposition the bath as needed so the bath drain is directly over the drain pipe.

Use lifting straps and get additional assistance to remove the 2x4 supports and carefully set the bath
on the floor. Adjust the bath position as needed to ensure that the drain pipe is in the center of the
bath drain hole.

Verify that the bath is level and that all support feet are in contact with the finished floor. Carefully
install shims under the support feet as needed.

NOTE: The drain cover and gaskets are included in a small box located within the carton.

Choose the thin drain gasket for PVC drain pipes or the thick gasket for brass pipes.

Apply silicone sealant to the inside and outside surfaces of the drain gasket to act as a lubricant.

Use a rubber mallet and short section of 1-1/2″ PVC tubing to install the drain gasket onto the drain
pipe.

Line up the tabs on the drain cover with the slots in the drain body, and insert the drain cover
assembly into the flange.

Press the drain cover several times to make sure the drain opens and closes properly.

Apply sealant.

Apply Sealant - Optional

If desired, apply a thin, continuous bead of clear or color-matched silicone sealant to the seam
between the bath and the finished floor.

4. Clean-Up

Clean-Up

CAUTION: Risk of product damage. Do not allow cleaners containing petroleum distillates to
remain in contact with the surface for long periods of time.

CAUTION: Risk of product damage. Do not use abrasive cleaners, as they may scratch and dull
the bath surface. Use warm water and a liquid, non-abrasive detergent to clean the surface.

CAUTION: Risk of product damage. Do not use metal scrapers, wire brushes, or other metal tools
to remove stains, paint, plaster, or tar. Use turpentine or paint thinner to remove stains, paint, or
tar. Use a powder-type detergent on a damp cloth to provide mild abrasive action to any residual
plaster.
