In other bath layouts, the tub may be opposite the sink and toilet, as shown here. The International Residential Code (IRC) requires a minimum of 21 inches (53 centimeters) of clear space in front of a toilet, so be sure to allow for this dimension — and more than the minimum if possible.
It is not uncommon to come across configurations that don’t meet minimum standards in older structures. But if you are remodeling, be certain to note the toilet dimensions in your project so you have adequate space.
There are standard-size toilets and elongated configurations. The elongated type will extend into the room by an additional 2 to 3 inches (5 to 8 centimeters).
