Installation Guide

2. Prepare the Site
NOTICE: Measure your product for site preparation. Note the model number on the back side of the
bath, then visit the product page at www.kohler.com for additional information.
NOTICE: Do not support the load weight of the bath by the rim.
Framing
Ensure the floor offers adequate support for the bath and verify the subfloor is level. Install
additional support and adjust for level as needed.
NOTE: This bath is designed for drop-in or island installation. If a deck-mount faucet will be installed,
plan a space on the deck to accommodate the faucet.
NOTE: Use wood or concrete framing. Wood framing will provide the best vibracoustic quality.
Construct the framing, taking into account the thickness of the finished materials.
Provide a 1/16 (2 mm) gap between the framing and the underside of the bath rim to ensure the
bath is not supported by the rim.
IMPORTANT! Several of the included bath components will be powered by the control amplifier via 25’
(7.6 m) cables. Plan the location of the control amplifier so the cables will reach without tension.
NOTE: If installing the control amplifier between studs, stud spacing should be 16 (406 mm).
Construct stud framing or a pocket for the control amplifier.
Provide a means to route the user interface cable through the wall to the control amplifier.
Plumbing
NOTE: For through-the-floor drain installation: cut a hole in the subfloor to accommodate the drain
connections.
Install the rough plumbing. Cap the supplies and check for leaks.
Attach the drain to the bath according to the instructions packed with the drain. Do not connect the
trap at this time.
