Tub-to-Shower Conversions

Removing an unused tub and replacing it with a walk-in shower opens up floor space, improves accessibility, and modernizes the bathroom. We handle the demolition, drain reconfiguration, and new plumbing rough-in, then coordinate with your tile installer.

Shower Valve Replacement

Old shower valves are a leading cause of temperature scalding and hidden leaks. We replace failing valves with modern thermostatic or pressure-balanced models that keep temperature steady when other fixtures run.
