Retrofit Sink for Coffee Bar
I have an awkward corner next to a staircase that I want to install cabinets on and make into a coffee bar.
I will be moving that outlet up and swapping to a GFCI if I get water there.
Right behind this wall is a toilet in the downstairs powder room and the PEX there runs cold water upstairs to a shower and tees to the toilet.
The drain pipe there is for the shower and an upstairs toilet, my gut feeling is that I can't use that drain pipe for reasons I don't understand fully.
The questions I have:
1. Can I just tee this water line with a PEX tee
2. How can I support the water stub-out in a retrofit like this and what products should I use to do the tee/stub-out
3. Can I use the drain line and should I saddle or use a Y
4. How can I support the drain pipe (if applicable)
5. Is a p-trap kit good enough (if applicable)
