Grohe Blue Installation: Professional Recommended

Grohe Blue installation requires more skill than a standard faucet installation due to the integrated CO2 line, filter cartridge connection, and cooling unit (Blue Chiller, sold separately). A professional plumber familiar with premium kitchen fixtures is recommended. Installation requires: a 35mm sink deck hole (standard for most kitchen sinks), under-sink space for the filter housing and CO2 cylinder holder, and an electrical outlet for the optional Blue Chiller. Grohe provides detailed installation instructions and a Grohe USA support line (1-877-476-4374). Grohe-authorized installers can be found through the Grohe dealer locator at grohe.com.
