Smallest Possible Half Bath
Final minimum half bath size.
Smallest possible half bath. A larger half bath is unnecessary and it s not likely that you d find that much extra unused space in your house. With all these considerations in mind i also need to find a space in my house to add a half bath. That little spot under your stairs calling for you to turn it into a lovely little powder room. With the smallest non corner sink on toilet i think it would be 30 x 46.
I m going to say 34 x 34 with the smallest corner sink on toilet. Our little half bath is 17 square feet if measured on the floor and the wall that the toilet is on was 39 1 2 high and angled up. Diy had to build out the wall so that we would meet code for the 6 foot 8 inch ceiling height in front of the toilet. If it s any smaller it will be uncomfortable for people to access.
Minimal dimensions for a half bath. You will have enough space if you can find a spot in your house that s about 3 to 4 feet wide and 6 to 8 feet long. Here s our before photo of the space.
