Before you begin to shop for a new toilet, you must measure the ‘rough-in’ size of your bathroom. This refers to the distance from the wall behind the toilet to the middle of the waste or drain line.
Round toilet bowls feature a circular shape and a compact design. These toilet bowls typically extend out approximately 28 inches from the wall. The smaller size allows them to fit into tight spaces and makes them a better option for households with small children. Round toilet bowls also tend to be less expensive than elongated toilet bowls.
Elongated toilet bowls feature an oval shape and typically extend out 30 inches from the wall. Many people find the elongated seat more comfortable because of the larger seat. The elongated shape allows for more sitting space and accessibility. This makes it a comfortable and useful option in your toilet remodel.
The flush volume of your toilet refers to the amount of water your toilet uses for flushing. Because your toilet is flushed multiple times a day, it can use large amounts of water. Most toilets will have a flush volume of 1.6 gallons per flush (gpf) in order to comply with the national standard. A high-efficiency toilet uses only 1.28 gpf or less, allowing you to conserve water and save money.
