Combining all 3 on a 2" is probably going too far. Since you're
putting this in concrete I'd err on the conservative side. If you
have a toilet in that location it's not like you have far to go to get
to the 3". You don't have space to make the bath separate from the
laundry? From a resale perspective a lot of buyers like a 1/2 bath in
the downstairs more towards the front entrance. That's why when you
look on many plans it is very common to see them off halls near the
front door.
