February 27th excerpt:

A loud guitar riff cut through the room, startling Sam in his seat and nearly causing him to scribble across his current page. They rarely got any phone calls, so it was a shock to hear. Sam turned towards the bathroom, where Dean was brushing his teeth (or so Sam assumed from the noises he could hear). “Hey, Dean!” he hollered, working hard to project his soft voice across the gap between them. “Phone!”

After a muffled reply from Dean, Sam got up and wandered over to the phone, one of those new smartphones with a touch screen that made it easy for him to use at his size. He smiled when he saw it was Jacob, but before he could hit the button to answer, Dean was stomping noisily over, trying to wipe his face off with a towel. Sam made a face. His experience with motel cleaning crews didn’t make him eager to use any of the towels in the room.

Dean’s hand swept down, scooping up the phone while Sam was offered his other hand in a far more careful motion.

( This has indeed come up before so I copied the answer from this post to save myself the extra work )

Before Sam hit the road with Dean, their family lived with an outhouse. It was placed under the motel, as deep as they could go to where they were able to dig holes. This was also used by Walt to dispose of the remains of the rats he would kill and skin. When full they would cover up the hole and find a different place to dig.

Afterwards, it became easier. Sam can simply use the sink in the bathroom. He’s able to get himself around the entire motel room without any help, and he doesn’t have to worry about being grabbed if he’s out in the open. For his teeth he can snitch some toothpaste from Dean while he’s up there. There’s only been one time Dean almost walked in on Sam while he was using the sink, and the scolding Dean got sent him almost running.

I’m probably not going to go any deeper in depth on this subject. Size and location have never been seen as a detriment on living for me. People will find a way.
