Shower Valve Rough-In Extensions

If your shower valve was installed too deep, you may need to purchase a shower valve extension. Signature Hardware carries valve extensions for some rough-ins, but not all. Professional installation should factor in the correct depth behind the wall, with any exterior wall covering included. However, if an extension is not available, it will be necessary to remove and reinstall the valve at the correct depth. 

Valve extensions and available concave trim plates are not covered under warranty, and concave trim plates cannot be ordered through our website. If assistance is needed, please contact our Customer Relations team via live chat at or send us an email at
