So this is what I am "trying" to accomplish. I am thinking about renting another warehouse building for my volleyball club and I need to add restrooms; 3 men's urinals, 3 men's stalls and 9 women's stalls w/a handicap stall in each one along with lavatories, 3 in each and 2 water fountains. I have no idea how much, especially having to cut into concrete for the sewer part. Please call me at your convenience, 210-789-7366. Thanks for all the suggestions, I will follow up tomorrow.
