Just built in Southern Oaks, the water heaters are placed at the front corner of the garage.
It takes 2-3 minutes to get hot water to the shower. Temperature drop is more than 10 degrees over that distance
If I had a do over, I'd ask if possible to place it closer to the center of the house.
Otherwise I'd talk to a plumber about installing a small water heater near the master bath sized to cover the time to get hot water from the main unit.
