Introduction
Please read these instructions carefully to familiarize yourself with the required tools, materials, and
installation sequences. Follow the sections that pertain to your particular installation. This will help you
avoid costly mistakes. In addition to proper installation, read all operating and safety instructions.
All information in this manual is based upon the latest product information available at the time of
publication. At Kohler, we constantly strive to improve the quality of our products; we therefore reserve the
right to make changes in product characteristics, packaging, or availability at any time without notice.
Before You Begin
This product is designed for drop-in island installation. Undermount and alcove installations are also
possible.
You must install the bath onto an adequately supported, level subfloor.
Provide properly dimensioned framing.
Choose a fill spout which will provide adequate reach and a minimum 2” (5.1cm) air gap above the
bathing well rim of the unit. You may need to build up the deck material to obtain adequate air space
because the outer rim may be lower than the bathing well rim depending on the specific area of the bath.
Follow local plumbing codes.
The unit must be filled with water through the bathing well, not the overflow channel.
If you plan to install a deck-mounted, hand-held shower, the diverter vacuum breaker must maintain a
minimum 1” (2.5cm) air gap above the outer rim.
When using the K-922 or K-923 Laminar Bath Spout with drip tray K-924, the distance from the finished
wall to the outside wall of overflow channel should not exceed 2” (5.1cm).
