Today's national water conservation code mandates that toilets are restricted to flush a maximum of 1.6 gallons. The rough-in dimension is the distance from the center of the waste, or drain, to the wall. Elongated bowls are more supportive of your legs, and their larger oval design is more comfortable. Since only the major plumbing manufacturers offer a few toilets that will accommodate your installation, there aren't any stylized or European design-oriented options available. Standard two-piece toilets in rounded and elongated bowl profiles are available in a choice of colors.
Types of Toilets Consider the room size, toilet area, and design.
These are fixtures that should match, as the legs or bases are usually stylized. A compact, wall-mounted European model with a concealed tank allows for a contemporary, open floor plan and it allows you to determine the seating height. The required in-wall tank and carrier must be planned for on interior walls. They can be found with both round and elongated bowl profiles. These models are generally more contemporary looking, but there are a few traditionally styled products available.
