Hi there! Apologies if my question is stupid. I have read the IPC but I’m still unsure. I’m redoing my bathroom and trying to figure out the right way to plumb it. I found this picture online and that’s exactly the configuration of my bathroom. My question is, does the tub not need an individual vent? Can it use the main stack as a wet vent? For info, distance from tub drain to main stack is 30”, and main stack to sink drain is 24” (small bathroom). Thanks in advance!
