1. Prepare the Site

NOTICE: Unless otherwise specified, floor support under the bath must provide for a minimum of 80 lbs./square
foot (390 Kg./square meter) loading.
CAUTION: Risk of property damage. Do not support the bath by the rim. Provide support under the legs.
- Make sure the flooring offers adequate support for your bath and verify that the subfloor is flat and level.
- When replacing an existing bath, disconnect the drain at the trap. Slip boards under the feet of the old bath to
protect the floor as you slip the old bath out.
- The bath should be installed in a drop in installation. Construct 2x4 or 2x6 stud framing designed for your
particular installation. Provide a 1/16" (2mm) gap between the bath rim and the stud framing. Frame the floor, or
construct a frame for a raised installation in accordance with the roughing in information packed with the bath.
- Use the roughing in cut out information to carefully lay out and cut the rough deck material.
- Position the plumbing according to the rough in information packed. Cap the supplies, and check for leaks.
2. Prepare the Bath
- Install the drain to the bath according to the drain instructions. Do not connect the trap at this time.
- Position a clean drop cloth or similar material in the bottom of the bath. Be careful not to scratch the surface of the
bath.
3. Install the Bath
WARNING: Risk of personal injury. Your cast iron bath is extremely heavy. Obtain sufficient help to carefully lift
or move the bath.
CAUTION: Risk of product damage. Do not support the bath by the rim. Provide support under the legs.
- Carefully move the bath into position.
- Insert the drain tailpiece into the trap.
CAUTION: Risk of property damage. Ensure a watertight seal on the bath drain.
- Level the bath by fitting metal shims under the bath feet as needed. The bath must be resting on all four feet.
Ensure bath is level along the top and across the drain side. If the feet are not accessible from the back or side,
move the bath in and out of position to shim it properly.
- In sunken installations, make sure there are supports placed under the bath.
