Bathroom entry doorway
NKBA Bath 1Description
The clear opening of the entry doorway should be at least 32 inches. Minimum 30" if the bathroom is small, but 32" is the recommended floor for accessibility and furniture move-in.
Why this exists
32-inch clear is the threshold below which a wheelchair can't pass and a 30-inch vanity can't be carried in. Universal-design recommendations push for 36" but 32" is the workable minimum for a typical home.
