How to Install a Linear Shower Drain

Before you begin, read instructions below carefully. Observe all local plumbing and building codes when installing the shower drain.

For the following instructions it is assumed that the shower pan and drain flange coupling are already in place. Your application and conditions may call for variations to these procedures. Signature Hardware accepts no liability for any damage to floor, walls, plumbing, etc., or for personal injury during installation. We recommend consulting a professional if you are unfamiliar with installing bathroom fixtures and plumbing.

Unpack and inspect the drain and parts for damage. If damage is found, please Live Chat or contact Customer Service. If you need further assistance while installing your shower drain, contact a professional.
