Hello - new to forum. I’m trying to get some education on venting - which always confuses me a bit. I’m building a small detached sleeping room with a small bathroom. My plumbing plan is something like pictured here. My question is whether I need the vent lines at all since everything is so closely coupled or whether I can allow the other drain lines to function as the vents if I use 3” on everything. This isn’t a code issue for me (no permits or inspections required)but just a function issue. For scale - it is 13 feet across the whole plan making the toilet and shower drain about 5.5 and 4.5 feet from the main drain line leading to the vent stack.
Waste lines in red - possible vent lines in green. This will be under slab
thanks in advance for any help you can provide
