Pride Plumbing came out and provided a cost estimate to replace a bathtub/shower faucet valve with a new Delta single function valve, add a Delta chrome trim kit (replacing the shower head, valve cover and handle, overflow cover, and downspout push button diverter) and convert the valve's copper above-floor hot and cold water supply lines to PEX piping and fittings; tying them into the home's existing copper main water lines.
