Jack of all trades
Hey everyone. I am in the process of remodeling the basement bathroom in our house in Cheyenne, Wyoming. It was origanlly very small and we are making it about 3 times the size. A 43" X 6'5" shower with double heads, A whirlpool tub, and a 7' counter with double sink. I am attaching some pictures of the room. My question is I need to move the shower drain about 2' (which I don't think is a problem) (the shower is were the ladder is in the picture). My problem is the sinks and tub drains. To the right of the toilet is a loop of pipe where the original sink was. I need to move drains to the wall at the right for the double sink and tub. I am presuming the loop was the vent for the sink. I am thinking I jack hammer the floor at that loop to the right going to the wall and then trench it along the wall for the 2 sinks and the tub. So how do I vent for the new location of the sinks and the tub? The tub will be at the end of the sink counter so there will be 3 drains on that line. There is a bedroom above so I can't take a vent up to the roof. Do I run a line up to the floor joists and outside then up along the outside of the house to the roof? Are there other options that are allowed by code? What size pipe would I use? Is the line that is there for the original sink big enough for the 2 sinks and the tub?
