This and I'm no plumber, but I'd imagine this would unnecessarily complicate the piping setup.

Edit: My notifications are full of so many conflicting answers lmao

I finally have some insight! I'm a commercial plumbing estimator. This layout features manifolds for waste, vent and cold water on 3 of the 4 walls. Each of these walls would need some larger chases to account for the size of the plumbing and carriers needed for each wall. Cost goes up.

Along with chases, the lengths of pipe are longer and more diverse making it difficult to prefab offsite and assemble in field. Think if every toilet needs 4 inch waste while urinals can get away with 2 or 3 inch pipe, spreading it out like this would make everything 4 inch.

When I say more expensive, we are talking my best guess. I'd say 30% more labor and 20% more material than a traditional back to back core restroom layout of equal size. Typed on my phone from work while looking at some restroom plans.

Not necessarily. Urinals require different carriers and different fixture units and drainage fixture units which is why they are normally put together, to make labor easier and the plubming more consolidated.

If the women's restroom or washroom has the same layout but with water closets only, it would still be more expensive with plumbing in 3 of the 4 walls needing chases. With normal core restroom layouts, you try to keep the chases consolidated I.E. shared chases and plumbing consolidated on at most 2 of the 4 walls.

I feel like men never get a break from being put down by other men. Either directly or implicitly with scenarios like the washrooms, they have to use from childhood onward.
