Checked the fuses and all seem to be okay. The thermostat does not do anything... Would you start by replacing that ?
Doesn't seem to be wet around the toilet but will check again like you said.
I think instead of replacing anything at this point you need to check some things. Can you check to see if you are getting 12v power at the heater, as ronfisherman mentioned?
You said the water was in the bathroom, is that not where the toilet is? In any case, turn on the water and see where the water is coming from in the area that was wet. If you have a helper you won't have to have the water running, and leaking, while you run back and forth between the faucet and the leak.
