Direct answer: When a shower handle turns but no water comes out, the most common causes are a blocked shower head, closed service stops at the shower valve, or a failed shower cartridge that is no longer opening the water path.
Most likely: If every other fixture in the house still has normal water, treat this as a shower-side problem first, not a main supply problem.
First figure out whether the problem is only at this shower or part of a bigger water issue. Then separate no flow at the shower head from no flow at the valve itself. Reality check: a handle that turns freely does not prove the valve inside is actually opening. Common wrong move: replacing the trim handle because it feels loose when the real failure is behind it.
Don’t start with: Do not start by cutting into the wall or buying a whole shower valve body. Most no-water calls get solved at the trim, stops, or cartridge.
Bathroom sink, toilet, or another tub still works, but this shower gives nothing at all.
Start here: Check whether water comes out with the shower head removed. That quickly separates a blocked outlet from a valve problem.
The handle moves through its normal range, but there is no trickle, no sputter, and no temperature change.
Start here: Look for closed service stops behind the trim or a cartridge stem that turns without moving the valve.
The shower was normal, then one day the handle turned and nothing happened.
Start here: Think recent work first: trim removal, cartridge replacement, house shutoff work, or a freeze event.
You may hear a hiss or get a brief spit of water, then dead flow.
Start here: Check for a clogged shower head or debris jammed in the cartridge after supply work.
Mineral buildup can choke the outlet enough that the valve opens but almost nothing gets through. This is especially common if flow got weaker before it quit.
Quick check: Remove the shower head and briefly turn the shower on. If water comes out of the shower arm, the blockage is at the shower head.
Many shower valves have small hot and cold shutoffs behind the trim plate. After repair work, they sometimes get left closed or partly closed.
Quick check: Shut off the water, remove the handle and trim as needed, and look for screwdriver-style stops on each side of the valve body.
The handle can still turn even when the cartridge stem is stripped, jammed, or no longer opening the ports inside the valve.
Quick check: With trim removed, watch whether the cartridge stem actually moves the way it should and whether it feels loose, gritty, or seized.
If the problem started after a hard freeze or after plumbing work, the shower branch may be frozen or packed with debris. This is less common than a head or cartridge issue, but it happens.
Quick check: See whether nearby fixtures on the same bathroom wall have reduced flow too, and whether the shower is on an exterior wall that recently got very cold.
You do not want to tear into the shower when the real issue is a shutoff, pressure loss, or frozen plumbing affecting more than one fixture.
Next move: If other fixtures work normally, stay focused on the shower assembly. If other fixtures also have no water or very weak flow, this page is no longer the right starting point.
What to conclude: A shower-only failure usually points to the shower head, valve stops, cartridge, or the branch feeding this valve.
This is the fastest clean split between an outlet blockage and a valve-side problem, and it does not disturb the valve in the wall.
Next move: If water flows with the shower head removed, clean or replace the shower head and retest. If no water comes out of the open shower arm, the problem is farther back at the valve, stops, or supply branch.
What to conclude: Good flow at the arm means the valve is opening and the blockage is at the shower head. No flow at the arm means the shower head is not the main problem.
A shower can act completely dead if one or both built-in stops were closed during past work. This is common after cartridge service.
Next move: If the shower comes back after opening the stops, finish reassembly and check for leaks around the trim. If the stops were already open or opening them changes nothing, move on to the cartridge check.
A stripped handle adapter or failed cartridge can let the handle turn without actually opening the valve. This is one of the most common true no-water failures.
Next move: If a new properly seated cartridge restores flow, run hot and cold through the shower and check operation through the full handle range. If the cartridge is intact and correctly installed but the valve still passes no water, the problem is likely debris in the valve body, closed upstream supply, or a frozen/blocked branch that needs more involved service.
By this point you have separated the easy fixes from the deeper in-wall problems. The next move should be decisive, not guesswork.
A good result: If the shower now has steady flow and normal temperature control, the repair is complete.
If not: If the shower is still dead, the remaining causes are usually inside the valve body or the branch piping feeding it.
What to conclude: Once the simple external causes are ruled out, deeper valve or supply issues need a more invasive diagnosis than most homeowners should push through blindly.

Usually the handle is no longer opening the valve, or water cannot get past the shower head, service stops, or cartridge. A loose-feeling handle often points to a stripped adapter or cartridge stem, but a clogged shower head is still worth ruling out first because it is easy and common.
Yes. Heavy mineral buildup or debris at the inlet screen can choke flow enough that the shower seems dead. Remove the shower head and test briefly at the shower arm. If water comes out there, the shower head is the problem.
A bad shower cartridge may feel gritty, bind, spin too freely, or fail to move water even though the handle turns. If the service stops are open and no water comes out with the shower head removed, the cartridge becomes a strong suspect.
Not as a first move. A whole valve body replacement is much more invasive and usually means opening the wall. Rule out the shower head, service stops, and cartridge first. Those are far more common and much easier to fix.
Treat that differently. If the shower is on an exterior wall and the problem started right after very cold weather, the branch may be frozen or damaged. Do not force the valve or keep testing if you suspect hidden freeze damage. That is a good time to call a plumber.
Yes. If one or both built-in stops behind the trim are closed, the shower may have no flow at all. This often happens after cartridge work or other service when the stops were shut and never reopened.
