Looking for some help with a major bathroom remodel we're in the planning stages for.
Background:
We're in NJ, so following NSPC 2021. We're DIY'ers getting some help from family with more experience but want to make sure we have a good solid plan before we apply for the permit.
The plan is to divide a large 2nd floor bathroom into two full baths. The current bathroom has a toilet, double sink, bathtub and separate shower. The joists run in direction indicated on drawing. We're basically going to divide the space with a wall and add a toilet and double sink (moving the existing toilet and bathtub).
The top drawing is the current layout. The bottom drawing is the proposed layout (changes are shown in orange). Drawing is not to scale; doors, windows, closets not shown (we already figured out clearances and have enough space). We also haven't started demo yet so are having a tough time figuring things out.
Some basic questions first:
1. For the new toilet on the left, can we move it as shown on the drawing on the bottom- approx 10 ft down, parallel to the joists? The NSPC seems to indicate it can be 10ft away if a 3" drain pipe is used with a 1/8" slope (is that right?). Does it matter what size the stack is? (I'm pretty sure mine is 3")
2. For the new toilet on the right, we're planning on going below the joists and making a soffit on the 1st floor to connect to the stack since we can't cut the joists that large. That would mean an approx 5ft run parallel to joists and then a 5ft run below the joists. Is that ok?
3. Any advice on how to create a riser diagram for the proposed drawing on the bottom? My uncle who's helping me says how to connect the pipes will be obvious to him once we demo but I have to submit the plan to the town for the permit ahead of time. I've been studying the NSPC 2021 and trying to see which of their diagrams match most closely to use as a guide but I'm just not sure and and I want to make sure my permit is approved and make sure this plan is possible before we demo anything.
4. Only the existing double sink on the left and the shower/tub on the right will be remaining in about the same location, everything else will be moving or being added. So if anyone has advice for the BEST way to plumb this I would love to hear it. We'll have most walls and the floor open so can remove existing plumbing and lay it out any way that works best. I'd rather take our time and do it right and not have trouble down the line, even if it is overkill for code.
Thanks so much for any help!!
