Friends are having a new home built and are having a friendly disagreement about where to place the bathroom light switches. She wants them on the wall outside the door because she just likes it better turning the light on before entering so you dont have to feel around on the inside wall for the switch. Also house she grew up in had the switches outside so she is used to that. He wants all switches inside the bathroom because he doesn't think anyone should be able to control the lights from the outside (bad college experience lol). In my house all switches are on the inside. Just made me wonder, is there a right or wrong? What's more common? I would guess switch on inside is the default? What about you?
