Connecting shower drain to toilet drain
Yes, I worded that a little wrong, I did mean slotting a trench. I'm not sure what you mean by venting. I know we have a vent pipe in the bathroom that I'm assuming was used by the old shower before. We have to vent the shower separately from the toilet, correct? This the the only photo I have on me at the time, but I'm assuming we'll probably need to get a plumber out here to answer the other questions. We plan to build the shower along the back wall, the toilet room is to the left just inside the door, and the sinks run along the wall on the right. Thanks for your help!
