Extension Deep Roughing-In Kits for Faucets
Kohler offers Deep Roughing-In Kits for installation situations where the mounting surface is too "deep" or "thick" for standard faucet installation. Deep Roughing-In Kits are considered part of a custom installation, as the product Specification Sheet indicates the standard roughing-in dimensions.
Current Deep Roughing-In Kit part numbers can be found on the Installation Guide and/or Specification Sheet for the faucet or valve.
The kit numbers can also be found in the current price book, located at any Kohler distributor or retailer. All kit numbers are available for purchase on us.kohler.com.
Note: Thermostatic Valve Trims do not offer Deep Roughing-In Kits. Instead, short, medium and long stem-extensions, called K-joints, are included with the trim. There is not a longer stem-extension option.
