Yes, you still need to vent the shower separately. And as GReynolds929 said, the kitchen sink needs a separate vent as well. The wet vent from the lavatory is only sufficient for venting the toilet in your current layout.Thanks for the reply MicEd69. I had another look at the framing and determined I could move the shower connection to the wet vent side of the wye fitting. In this configuration do I still need another vent on the shower line?View attachment 43106
