Much Needed Bathroom Remodel - Please Share!!!!

My cousin recently got married!   Now a bathroom that was just big enough for one person is required to hold TWO people! There is only one vanity, a toilet and a tub.  There is also a plumbing problem - the stack needs to be replaced and when you flush the toilet, gases come up through the tub.  You have to run water in the tub to stop the smell.  I can come up with half of the money $5,000....but they received 3 bids and they were all around $10,000.  They really need a new bathroom!!!!!  I figured asking here couldn't hurt.  I really want to surprise her for their 1 year anniversary in June!  Please help fund a new bathroom for a loving and giving couple!!!!!  $1, $2, $5.  Every cent counts!!!!  Or...please share the link below on your page!!!  That helps too!

Thank you for your help!!!!!
