Bathroom is 5'7 x 9.

This is looking into the bathroom from the office. The left wall butts up to a closet. Rear wall butts up to the kitchen area with sink. Right wall is the exterior.

Looking at right wall. Shower would be on the right and toilet on the left. 437355e6b4fbbd824b59bfb93f55e4da.jpg

Left wall. To the left will be the washer/dryer (rv style unit) to the right will be the bathroom sinkcb45d8fca002024c33e23a22f58b60a7.jpg

Close up of toilet/shower and what I have to deal with as far as water input to the building. I stubbed up both per and 3/4" pvc as I was unsure what to go with. 1840ae4be0ebc8cc1888ce13d07f28e4.jpg

Close up of the left and rear wall drains stubbed up front concrete.


I have 2" pvc stubbed up for the drains.

I did all this myself but I am no plumber obviously.

Questions

1. My plan is to stub out for the bathroom sink on the left wall, y off it to the washing machine. Continue up to the ceiling from the sink and 90 back to the right wall and then straight up out the roof for a vent.

Is this adequate venting for washing machine, bathroom sink, shower, toilet and kitchen sink. All within 10' of the vertical vent through the roof?

2. The plan is to run the 3/4" pvc stubbed up from the concrete to the hot water heater that will be directly above the shower upstairs. Also teeing off to catch all the cold water fixtures but reducing to 1/2". Is there some reason I should not put the hot water heater upstairs?

3. Plan is to come off the hot water heater in cpvc 1/2" and catch all the hot water fixtures. Is there a reason rather than going in the walls rather than in the ceiling for both hot and cold water lines? It will be much easier for me to run the lines in the ceiling (made a mistake framing)

4. Shower. I was hoping to get a 32"x32" 2 piece shower unit from HD and frame another wall between the shower and toilet. As you can see in the picture it looks like the 6x6 is where the shower fixture would need to be. Ideas?

At this time all I have is the water and sewer line stubbed out of the footprint of the building with caps inside a box that I buried so the bathroom still won't be functional at this time but I really need to get the bathroom insulated, drywalled and painted so I can move on to other areas of the shop.

Also, I have a 12/2 wire running from breaker box to where the hot water heater will be. I have thought about running a switch that would be near the toilet so I could turn it off when not in the shop for long periods of time rather than hitting the breaker. Good idea? Bad?

Washing machine also has to have a trap. It can share the Y-waste line with the sink but unless it drains into the sink it can't be "open pipe".

I think upstairs water heater is just fine. Very common in industrial/factory restrooms. I would just try to make it easily serviceable/replaceable as that day will eventually come.

The waterlines do not care where they are run, ceiling or wall, however its always good to plan for those cold snaps when it could dip below freezing.
