What is the amount of room needed for a toilet
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. Recommended: Plan a clear floor space of at least 30 inches from the front edge of all fixtures (lavatory, toilet, bidet, tub, and shower) to any opposite bath fixture, wall, or obstacle. Code Requirement: 1  A minimum space of 21 inches must be planned in front of lavatory, toilet, bidet, and tub. This means that if the door width is 32 inches, you must have a passage of 32 inches wide and 32 inches long of clear space leading into the bathroom. Once inside the bathroom, you will need a minimum of 21 inches of space in front of the toilet, sink, tub or bidet and 24 inches of clear space in front of a shower. (The NKBA actually recommends 32 inches.) There should be at least 24 inches of clear space in front of a toilet or bidet. Bathtubs. While there are no code requirements for tub size, minimum clear floor space alongside a bathtub should be at least 60 inches long (the length of a standard tub) and 30 inches wide. So the bathroom's narrowest dimension is 30 inches. IRC also requires at least 21 inches of clearance in front of the toilet bowl. There are bowls that stick out only 20 inches from the wall, which means you need a minimum footprint of 8 ½ square feet just for the toilet. Showers require a minimum of 30 inches of space into which a 30 inch diameter circle could be drawn. Because this is a very tight fit for most people, the recommended space for a shower is 36 inches. The ceiling in your bathroom must be at least 80 inches at the front of the sink or toilet and inside the shower. The National Kitchen & Bath Association requires at least 24 inches clearance in front of a toilet. Moreover, the NKBA recommends 32 inches from the center of the toilet waste line to the center of that of any other sanitary fixture, although local codes may require only 30 inches. Toilet clearances are an important consideration when planning a bathroom remodel or a new bathroom. These include not only the distances between the toilet and the back and side walls but also the clearance in front of it and the distance to other sanitary fixtures. While there are no code requirements for tub size, minimum clear floor space alongside a bathtub should be at least 60 inches long (the length of a standard tub) and 30 inches wide. Always allow clear space for access to plumbing and/or whirlpool motors. Sinks require a minimum of 20 inches of space to sit in, if they are the only sink in the room. Showers require a minimum of 30 inches of space into which a 30 inch diameter circle could be drawn. Because this is a very tight fit for most people, the recommended space for a shower is 36 inches.
