: We are trying to put in a new bathroom, tub, sink and toilet. Here's what we were thinking; : Starting at shower;2"drain to sink area where the sink 1.5" ties in then continuing with 2" to 3" drain after toilet elbow. : Venting;2" going up from tub over to sink hooking up with sink then going over to 3" vent stack . : Sound OK? Did I loose ya? : Oh one more ? The inspector says that if we are ever going to put in a second floor bathroom he wants 4" vent stack all the way. Any comments? : Thanks No, this doesn't sound like the toilet is being vented. It also sounds like the tub and sink drainage are being connected to the toilet trap arm--a no-no. You cannot use 1-1/2 under concrete. Deb The Pipewench
