so day 4 of my lovely home reno project... my buddy questioned where i wanted the shower head and plumbing located. seeing as i had confirmed time frame [multiple times], work scope, plans i'd drawn up both on paper and drafting software [in person and via email], walked through the potential layout [over lunch], and showed him all the components i'd bought... i was pretty pissed when he said, oh i didn't know you wanted that there. i guess were ripping out this wall too, since we need 6" for a wet wall and the existing studs are only 4".
