Questions about 6×12 bathrooms
Is a 6×12 bathroom big enough for a walk-in shower?
Yes. A 30″ × 72″ walk-in shower fits on the 6′ wall in place of a tub (Plan B), and the toilet and a 60″ vanity still keep their clearances.
What's the largest vanity for a 6×12 bathroom?
60″ with a tub or 60″ shower on the short wall, and 48″ with a 36″ corner shower. At those widths the toilet sits at the 15″ code minimum on each side. Our plans show 60″ and 48″ by default, which leaves a more comfortable 18″ when the room allows it.
Can a 6×12 bathroom have a bathtub?
Yes. A standard tub fits across the 6′ wall with the toilet and vanity beside it on one plumbing wall (Plan A), and a tub along the long wall works too (Plan D).
Which door works best in a 6×12 bathroom?
An in-swing door works in Plan A, Plan B, Plan C, Plan D at this size. A pocket door frees the swing area and needs about 30″ of plain wall beside the opening; an out-swing door needs the same clearance in the hallway.
