The scale you use is a PITA and I never want to count the squares on graph paper so do the drawing where 1 square is 6" that help . we need to see where the plubing is since moving toilets are a big issue for sure. Some pics posted here in a comment and allthmwasurements clearly marked this seems like a huge space for a bathroom so maybe a list of things you want in thta space . Where is the bedroom that this is attached to and where is the closet.Do you bathe on a regular basis? I really dislke FS tubs I find they a re pretty to look at and honestly a PITA to get in and out of and the space needed to be able to clean around them is a big deal.You have the space but we need some idea of exctly what you need in this spac e.
