What To Consider While Choosing A Dual Flush Toilet?

Dual Flush toilets are gaining popularity for their eco-friendly and cost-effective design among people. These toilets offer two options for liquid and solid waste and help you use only the needed water. But this is not enough; to find the best dual flush toilet, make sure that the toilet has the following features so it is optimal for you and your family.

Shape (Elongated or Round)

The shape of the toilet is a crucial feature that should be considered when buying a dual flush toilet. Before making your final decision on which shape you should get, consider the space in your bathroom.

Elongated Bowls

Featuring an oval shape, elongated toilet bowls provide extra seating space for enhanced comfort. These modern designs can easily fit into various bathroom styles. However, they require more room than round toilets, making them less suitable for compact spaces.

Round Bowls

If you have a smaller bathroom or limited space, round toilets are the ideal choice. While they might not be as comfortable as elongated bowls, they’re generally more affordable and can fit better into tight corners.

Before purchasing the dual flush toilet of your choice, you must consider the seat height and see if it is compatible with your height. There are two types of toilet seats regarding their height; standard height and comfort height.

Standard Height

With a seat height of around 14 to 15 inches from the floor, standard toilets are perfect for shorter individuals and children. They are easily accessible and convenient for daily use.

Comfort Height

Also known as ADA-compliant toilets, comfort height toilets have a seat height between 17 and 19 inches. They are ideal for people with mobility issues, the elderly, and taller individuals. While more comfortable for some users, these toilets may not be appropriate for everyone, especially kids.

Flushing System

Since you are buying a dual flush toilet, you must consider its flush system because they are designed to conserve water and the toilet you need should be both efficient and water conserving. Also, you need to make sure whether the flush system is strong or not. In the market, dual flush toilets have two types of flushing systems, gravity flush and pressure assisted flush.

Gravity Flush

A gravity flush system depends entirely on water pressure and gravity for a powerful flush. These systems are more widely available, reasonably priced, and comparatively simple to maintain. They are quieter than pressure assisted flush toilets.

Pressure assisted Flush

Pressure assisted flushing systems deliver a powerful clog-free flush using compressed air to boost water pressure. While they excel at waste removal, they can be noisier and more expensive than gravity fed systems. 

GPF (Water Use)

Another feature that must be considered when selecting a dual flush toilet is the gallons per flush (GPF). Toilets with lower GPF ratings are more water-efficient, helping you save money on your bills and conserve a vital resource. Generally, dual flush toilets use less water for liquid waste (around 0.8-1.1 GPF) and more for solid waste (1.6 GPF).

Many do not prefer higher GPF toilets as they use more water and are not certified by EPA. However, they can give a strong flush.
