To fix two switches that don't work in your bathroom, you will need to first identify the source of the problem. Here are some steps you can take:

1.Check the circuit breaker or fuse box to see if the circuit has tripped or blown. If it has, reset the circuit or replace the fuse.

2.If the circuit is not the problem, remove the switch plate and inspect the wiring. Make sure all the wires are securely connected to the switch and that there is no visible damage to the wiring.

3.If the wiring appears to be in good condition, the switch itself may be faulty. Test the switch with a multimeter to see if it is working properly.

4.If the switch is faulty, it will need to be replaced. Turn off the power to the circuit before replacing the switch.

5.Once you have identified and fixed the problem, turn the power back on and test the switches to make sure they are working properly.

It's always a good idea to hire an electrician if you're uncomfortable working with electrical wiring.
