No room for an extra bathroom? It’s a rare home where this is really the case. A bathroom can be squeezed into an amazingly small space. An area 3 feet by 5 feet handles a sink and toilet; 3 feet by 8 feet is enough for a shower too.
Architects maintain that a second or third bathroom can be squeezed into almost any house. Bath fixtures fit into less space than most people think. Into 25 square feet, you can squeeze a complete – if cramped – shower bathroom which would keep the cost to add an extra bathroom low.

Where to Find Space
Look for the space in places like:
Hallway: The untraveled end of a hallway, sometimes with a window, may contain as much as 30 or 40 square feet – sufficient space for a bathroom.
Closets Back-to-Back: Opened up, adjoining closets sometimes measure as much as 4 feet by 4 feet.
First-Floor Laundry: Streamline the laundry room with modern stackable washer/dryer appliances that take up less room - then reclaim the space to add a half bath.
Existing bath: An average sink, toilet and tub need a minimum of 5 feet by 6 feet. Some large bathrooms can be split into two by relocating the fixtures.
Under a staircase: A sink and toilet usually will fit under the stairs. Just remember to check the headroom before you begin the project.
Part of a Bedroom: Take a 3 foot slice from one side of a large bedroom. Put a toilet at one end of the new room, a shower stall at the other and a sink opposite a door in the partition.
Walk-in-Closet: An oversized walk-in bedroom closet or hall linen closet could easily become a half-bath with few structural changes.
Other Tips
Have the door swing out, or install a sliding pocket door.
Ventilate windowless rooms with a ducted fan or pre-fab skylight window.
Place new fixtures near existing water and waste lines for a lower plumbing bill.
Check floor joists: Conventional fixtures weigh up to 20 pounds per square foot; tile in mortar up to 30 pounds. On spans over 11 feet, better double 2x8 joists on 16 inch centers.
