I have a couple questions for you regarding my roughed in basement bathroom, but here's a photo first:
Obviously, the 4" pipe (closest in image) is for the toilet, but the two 2" pipes on the right I'm unclear as to their intended purpose. I assume one is for the sink, and the other is ........? Maybe a shower, but they're way to close together to be meant
to be sink and shower in my opinion.
Here's are my goals:
#1 Install toilet
#2 Install sink
#3 Install shower
#4 Plumb wet bar
#5 Build a raised "platform" for the toilet, sink, shower to sit on.
Here's a few notes to give you a visual of my goals, ideas and to explain my home's particular construction in regard to sewer.
- I'd like to build a raised 'platform' with 2" X 6" and double layer 3/4" plywood. I'm doing this for two reasons. One for 'fancy' effect and the other to provide under-floor routing of the shower waste pipe. When complete, it will be ceramic tiled like the concrete floor shown in the photo.
- The wall on the right is the concrete foundation wall.
- The studded and insulated wall on the left is an interior wall. On the other side of it is a wet bar, the sink is located just about center point in the studded wall.
- The 3" black pipe on the left carries waste from the kitchen and utility closet and one bathroom. The 3" black pipe on the right, goes towards the foundation wall, turns to the left and travels about 25' to carry waste from one bathroom.
of the sinks in the main floor have those "check valve" type vents. Nothing travels to the roof. Unknown how the showers and toilets area vented.
- The sewer is septic, not public. The basement floor drain and the main waste stack flow naturally to the first septic tank, so no pumps are needed.
- I bought a pedistal type sink. I'd like to install it at a 45 degree angle in the corner directly across the room based on viewing angle. I'm standing in the doorway of the room when I took the photo, so the sink would be the main focal point when you walk in the room. The toilet (of course) would be to the left, and the shower would be located out of frame to the right.
- The room is 7' X 7'.
Ok, that's everything I can think of. Here's my specific questions:
#1 Can I install drains for the wet bar sink, toilet, bath sink, and shower to the existing pipes shown in the photo?
If so, then "what goes where". That's my main question.
#2 How do I vent things? There's no main vent stack to the roof to tie into. Can the check valve type vent be used for everything I've got?
Plumbing is an area I have 'moderate' experience with, but new construction is fairly new to me.
Thanks in advance,
