I just was talking to a guy at work the other day about this. He said his dad recently plumbed in a faucet with a ~40ft run from the water heater. He ended up using 1/4" copper to get the hot water there, and the speed with which you get hot water was obsurdly fast he said. You can't run too much off 1/4" copper, but even 3/8" would be good for a bathroom I bet.
