5×9 Bathroom Layouts
A 5×9 bathroom is 45 sq ft (60″ × 108″). 4 of 4 standard layouts pass code clearances at this size. With a tub or a 30″-wide shower on the short wall, the widest vanity that keeps the toilet legal is 48″ (the plans default to 42″ for more elbow room).

Questions about 5×9 bathrooms
Is a 5×9 bathroom big enough for a walk-in shower?
Yes. A 30″ × 60″ walk-in shower fits on the 5′ wall in place of a tub (Plan B), and the toilet and a 42″ vanity still keep their clearances.
What's the largest vanity for a 5×9 bathroom?
48″ with a tub or 60″ shower on the short wall, and 42″ with a 36″ corner shower. At those widths the toilet sits at the 15″ code minimum on each side. Our plans show 42″ and 36″ by default, which leaves a more comfortable 18″ when the room allows it.
Can a 5×9 bathroom have a bathtub?
Yes. A standard tub fits across the 5′ 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 5×9 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.
