I used to toke in my bathroom before I moved to a different house. I'd wait till mum was in bed, then go in, have a hitter/bowl or whatever I wanted, but only after I turned on the shower. I made a practice of blowing smoke in the shower water, like a reverse bong i guess... and then I'd have the best shower in the world, spaced out and ripped off my can.

Now, I either rip a hitter in my room when no-one's home (and ghost it-don't do that too often) or I'll tell mom I'm going outside to smoke my pipe at night before bed and go on the porch and puff it up.
