Toilet stub(center) should be 12 1/2" from studs--12 from finished wall surface
Shower ----pan is mounted to the studs---get the specs from the manufacturer---
leave a 10x10 boxed in opening for the shower stub to give you some adjustment---
most times I will leave that area open and add the P-trap at the time of the pan installation--then pack with gravel and add a
thin skin of wet concrete as I install the pan---
