When a shower has no water coming out, the culprit is usually a closed shutoff valve, a broken tub spout diverter, heavy mineral clogging, or a faulty valve cartridge.
To start fixing it:
Most often, it's caused by a clogged shower head, a diverter that's failing to redirect water, a partially closed shutoff, or a worn-out cartridge. Mineral buildup or debris can quickly block the tiny passages in your shower head, which makes the flow weak or stops it entirely.
When your sinks work perfectly but the shower has no water, the issue is isolated to the shower's plumbing. It is usually caused by a bad valve cartridge, a broken tub diverter, a closed internal shut-off valve, or a clogged shower head.

To quickly unclog a cold water line, turn off the water main, disconnect the supply line from the fixture (like a faucet or toilet), and turn the valve on briefly to check for blockages. Clear any visible sediment by soaking in white vinegar, or replace the supply line entirely.
5 Signs It's Time to Replace Your Shower Valve
To unclog a showerhead, fill a plastic bag halfway with white vinegar, secure it around the showerhead with a rubber band or twist tie, and let it soak for one to three hours (or overnight). Afterward, remove the bag, scrub the jets with a toothbrush, and run the water to flush out the debris.

It's a good idea to bring in a plumber, especially if you are learning how to replace a shower valve for the first time. Once your new valve is in place, restore water flow and check for any leaks around the connections. If it is all good, go ahead and reinstall the trim plate and handle.
