Windows occupy the wall where mirrors are required in this Bathroom Floor Plan, but this design allows for the best of both worlds, along with sliding mirrors hung on barn door hardware. The door behind this free-standing tub serves as an attic access hatch. Understanding these rules of thumb and then building or expanding on them to create something great is an exercise in design with this Bathroom Floor Plan. Push the boundaries of what your bathroom can be, and make it better than the vast majority of other bathrooms! The design will not be perfect the first time you lay it out. Or, at the very least, the first ten times. You have many options to fine-tune everything when it comes down to inches.
