Hi,
I am currently in the process of converting an old bedroom in to our new bathroom. The job has been quite the challenge. Our house was built with concrete block exterior walls. The bedroom was added on to the home after it was built, so all four walls are block. To make matters worse, there is no basement under the addition, and the floor joists are 2x8. They run in the most inconvenient direction for running drain plumbing.
This all has caused many challenges for this particular job. Especially when it comes to running drain vents. I had to add a soffit to run some of the vent pipes, as well as fur out a section of one wall behind the shower and tub to run the main vent stack.
Where I am getting stuck is on the bathtub vent. It is a deck mounted whirlpool type tub. The way the bathroom is being laid out is making it near impossible to put in a drain vent without boxing out a section of the wall near the tub. It will be real unsightly to do this. That wall is concrete block, and has 3/4 furring strips with 1/2 drywall attached. There is no room to run a vent behind the drywall.
So. Can I run an island vent for a bathtub? MN does not allow an AAV. I have included these images so I don’t have to describe the current layout, or what I am intending to do. My only other option is to run the vent up at a 45 until it hits the nearest wall, and have it meet up with the vent inside the soffit. If I do that, it will have to be boxed out right there.
