Well, I have 49 inches of space and I need to fit a 27 inch 1-18, a 4 inch drain pipe, and a 19.25 inch Duratub sink... 27+4+19.25=50.25... That's the issue, how to fit 50.25 inches into a 49 inch space.... I suppose I could make the plumbing 2 inches wide instead of 4... I'll have to run that past dad first but I think I can make this work... I hope so at least...
