Hi there,

I enjoy a lot this website. I have used your recommendations on small projects and they have saved money and time.

Next week I will start with my first bathroom project. To be honest I am excited and a little worried of the outcome. I have attached a drawing of my bathroom plan. Blues are existing, reds are proposed.

As you see I need to start from scratch. I have an outlet drain that I am using for my washer wastewater. I would like to build a toilet, a sink and a shower in between the existing drain and the drop down sewer lines from upstairs. I am planning on using the existing drain (washer) as the shower. I am worried to have all these connected together. I would like to know if that is OK. Anything I should consider? I would also like to know if I need separate vents for each one (toilet, shower, sink, etc) or can I attach it to the existing one?

I am concerned about the floor. I am anticipating rebar in the area. Any tips?

I also have a drain opening in another area of the basement. Here come a dumb question but I have to ask, I feel like you guys would lead me in a good direction: Can I install a urinal using this drain? The urinal will be elevated about a foot over the drain so I can come up with a trap vent. I don't have no more drains in the basement, that one is it.

Thanks in advance for the help.

Coupla problems. Code says you can't flush a motorized drain [washer, dishwasher, or disposer or sump pump] past a toilet or tub or shower. The washing machine can have a 2" trap but the first connecting pipe to another line must be 3". Bring 2 3" pipes in the ditch. one for the washing machine and one for the other. if the pipe for the washing machine is less than 10' from where it connects to the main, use a 3" trap underground with no vent. Use 2" for the shower trap and line to the vented line and the shower line must be under 8' long. Watch out for footers. I always hated breaking footers. I was afraid the foundation may settle. Ask an engineer to be safe on how much footer to remove.
Where you going to tie a vent in?

I'm not sure exactly if this would help you or not but have you considered a macerating pump. Google Saniflo they have a pretty good website explaining when and why you would use their pump. I know pumps aren't the most ideal thing to be relying on but it would save you from having to demo you concrete floor.(which is why the pump cost about 700 bucks)
I'll be using one in my basement because my drain is about 2' above the floor. Hope this helps.

Oh and one more thing. Even if you use the pump each appliance needs to still be properly vented. How you would do that in your system I haven't a clue?

Thanks for the answer it was sure helpful. I will connect new vents with existing vents. I'll have to work around a lot of wood to create new vents. Is this OK?

Thanks for the answer. I should not have problems with the footer, hopefully. But I will keep it in mind if I encounter it. I will tie vents with existing vents from the uptair bathrooms and kitchen. Should I create a new vent, or can I connect to existing ones?

I meant to hit the agree button, but it was to late, apologies. Your answer was very accurate. Very informative.
