Reader Question: I need to replace my toilet. What should I consider?

Today’s residential toilets are federally mandated to use no more than 1.6 gallons of water per flush. There are two flushing systems to choose from: pressure-assisted and gravity-fed.

The pressure-assist toilets use compressed air to move water from the tank to the bowl. The toilets are noisy and more expensive but their extra muscle can prevent clogging in especially long or older, narrow drains.

The gravity-fed toilets use the water weight to generate flushing pressure. These toilets are quieter and require less maintenance. Gravity-fed toilets are available with a dual-flush system. Dual-flush toilets give users the choice of a .9 gallon flush for liquid waste or the standard 1.6 gallon flush depending on the need.

You’ll need to decide between one-piece and two-piece toilets. The standard toilet is a two piece model consisting of a tank and bowl. The two pieces are joined during installation. One piece toilets are cast as a single unit. The streamlined appearance is preferred by most designers and is growing in popularity.

Next you will want to consider bowl shape. Most people consider the elongated bowl more comfortable than the round bowl because the longer shape offers a larger seating area and more leg support. Unless the bathroom is extremely tiny with a clearance problem, select the elongated bowl.

Another comfort consideration is the height of the toilet. The Americans with Disabilities Act (ADA) of 1990 required that toilets stand 17” to 19” high. Though these toilets are typically 1½”- 2” higher than standard models, they are more comfortable for everyone to use. Retailers are now referring to these toilets as “Comfort” height toilets.

While toilets come in many styles and colors, most do not come with a seat. Remember to select one so you will not have to make a return trip.
