Shower stall lighting in a newer house has to be protected by a Ground Fault Circuit Interrupt device. Check the outlet in the bathroom to see if there is any power to the outlet, or, if the reset button needs to be pushed.

If reseting the outlet restores power to the shower stall light fixture and there was power to the receptacles in the GFCI outlet even though it needed to be reset, the outlet itself is wired incorrectly. Power from the panel has to pass through the GFCI circuitry in the receptacle before going to the outlet. If connected backwards, the outlet can have power even though anything downstream from the outlet is turned off when the GFCI circuit is tripped.

If your outlet in the bathroom is off and not a GFCI receptacle with the "push to test" and "reset" buttons, look for a GFCI receptacle in another bathroom to reset. If all bathroom outlets are off and none are GFCI receptacles, check the GFCI outlet in your garage. If none there, look for a GFCI breaker in your panel.

If you house is old enough to not have GFCI protection for the bathroom outlets, the problem with your light could be a bad switch in the wall. Try wiring the light direct without the switch to see if it works. Make sure you turn off power to the circuit before you start unhooking live wires from the switch and connecting them directly to the light fixture. If you wire past the switch and have no power at the bulb, the problem may be in the junction box in the ceiling beside the fixture. The wiring box usually has a removable plate that can be accessed from the opening for the fixture.
