Make sure a 12 volt pump is rated for hot water use. If you were able to get to the piping, pipe insulation would help somewhat.
45-60 seconds is pitiful. Ours takes maybe 15 seconds or so. Could the hot water be mixing with cold somewhere? I think I read about someone having that problem with their kitchen faucet but can't remember what the cause was.
At the very top of my list. Hot water is a good hint.
I have the Atwood g16ext that gets water hotter than a cherynobyl reactor core if the mixing valve sticks.
The vanity is at the center of the full wall slide on the drivers side. The hot water heater is located right rear, a rather long run.
