I've been considering doing this.
1. Find circuit breaker for electric hot water heater. (turn off LOL)
2. Run hot wire from CB to new switch (120 volt, 15 amp) on control panel.
3. From the new switch use the return wire in the romex (3 wire and ground 14 guage) back to the circuit breaker and attach to wire to the hot water heater. or you can run back to the hot water heater itself.
This is the basic circuit to add a switch inside for electric hot mater heater. All you are doing is adding a single pole switch to turn on and off. If you have a switch with a light you will use the white wire (neutral) back to the electric panel and common neutral buss.
