May be needed if you have a stall shower with a center mounted single lever water control knob (as pictured below) which the ShowerStick may hang down in front of. The ShowerStick when installed, will hang 36″ down from the tip of your shower pipe to the bottom of the shower hose loop (20″ to the bottom of the ShowerStick body (41″ and 25″ with KDF filter installed). The Offset Connector will allow you to offset the ShowStick to either side of your water control knob. (You don’t need this in a tub shower because they have faucet controls mounted low enough to not interfere with the ShowerStick being able to hang unobstructed.) Includes a large suction cup to position the body of the ShowerStick to keep it hanging straight. Note: The suction cup that’s included with the Offset Connector is only used to help keep the ShowerStick hanging vertically and is not used to support the weight of the ShowerStick.
