not this one. Its an old 3 handle valve that I have to cut out and solder in the new one. Done it plenty of times at work, just not very motivated to do it at home lol. Still probably 1 1/2 tops for me.
i'll help - wings. call one of your subs and tell them "if you still want to get work from me, you're going to come change out my shower tub valve one evening this week" ... no reason you can't be like EVERY OTHER contractor, occasionally.
