Basement built thread. Getting city permit with my awesome drawing :-)

Sinks have to vented in a certain way, I'm not a plumber but I'm pretty sure you can't just tie sinks in together especially since I believe the toilet and the shower are actually using the sink vent. Be sure to verify exactly how that all needs to be connected with a plumber before getting too far.

Personally I think I'd move the bathroom rough ins a little, reposition everything so the bathroom runs the other way and eats up some of that mechanical room space. Make the bar a u-shape and push that into the mechanical room as well, then put the tank in wall behind the bar so the fish room can go in the mechanical room. Fish rooms that eat up floor space will kill your resale.
