Most codes require at least 15 inches (measured from the center of the toilet) from any side wall or obstruction and not closer than 30 inches center to center to any other sanitary fixture. (The NKBA actually recommends 32 inches.) There should be at least 24 inches of clear space in front of a toilet or bidet.
In addition to requiring clear floor space in front of the toilet, building code and accepted rules of bathroom design outlined by the National Kitchen and Bath Association also require space on each side of the toilet. To pass code, the toilet needs a minimum of 30 inches of space to sit in by itself. This means that if you drew a line down the center of the toilet, 15 inches out to each side from this line must be clear with no wall or other fixture entering the space. If you have the room in your small bathroom, however, NKBA guidelines recommend 36 inches of space for greater comfort for the user.
