Puget Sound Plumbing and Heating provides repair services to Grohe faucet owners in the Seattle area. In addition, Grohe has a limited lifetime warranty program that sometimes covers defective faucets or faulty professional installation. It does not cover normal wear.
Customers who think that their Grohe shower faucet problems are due to a manufacturing or professional installation defect can fill out a warranty claim on Grohe's website. Grohe takes one to two weeks to process warranty claims.
Puget Sound Plumbing also offers installation services for new faucets, in addition to their repair services. As companies that advertise Grohe shower faucet repair services are rare, there are several other companies that, while not offering repair service, have a selection of Grohe shower replacement parts, as in the case of the Chicago Faucet Shoppe.
