Three Best Dual Flush Toilets

Best Dual Flush Toilets

When it comes to dual flush toilets, there are several options available depending on the model and manufacturer. An elongated toilet offers more sitting space. Other toilets with this flushing technology offer different sizes to accommodate height differences in people. Toilets also come in a variety of shapes, enabling homeowners to get the best one for their bathroom area.

Best Quality: Swiss Madison Concorde

Swiss Madison is known for its clean, minimalistic design, durability, and distinctive style. The Concorde offers a sleek one-piece curvy design that is easy to keep clean but still maintains a square shape and rounded edges for a very linear appearance.

To make this dual flush system toilet even easier to sanitize, the seat unlatches using a quick snap accompanied by a push-button removal. There is no need to unscrew or pry the seat off to clean it. The seat consists of a durable ceramic, slow-closing lid, preventing it from slamming, causing injuries, or cracking.

The Concorde flushes 1.28 gallons (powerful flush) and 0.8 gallons (little flush). The smaller flush is ideal for liquid waste while the powerful flush is for solid waste. The buttons are white with chrome trim and at the top of a narrow toilet tank. The trap on this toilet is concealed, and the design has a small footprint.

The challenge with this toilet may be the toilet seat. It is often difficult to find replacements for customized seats. The one on this toilet looks great, but the square shape may not be very comfortable for narrower hips. This toilet is ideal for secondary bathrooms with less traffic or if you can ensure that it wont get easily damaged.

Things to Consider

If water conservation is important, find a toilet with a dual flush system that is EPA-certified. This designation means the toilet uses 80% or less of the EPA’s standard of 1.6 gallons. The measurement is not based on cistern size but on the number of flushes.

Furthermore, while some use only 0.8 gallons to flush, some require more than a single flush to remove solid waste. If you can, find a store that will allow you to test it before purchasing the toilet. A dual flush toilet isn’t worth the additional cost if extra flushes cancel out any savings.

Find a toilet that is the right height for your body. The standard is 17″, but they may go up to 18″. The shape is additionally a concern. Round toilets are great for a small bathroom, while an elongated bowl is more comfortable in terms of seating. D-shaped, square, and rectangular toilets provide wonderful aesthetics, but all come with their drawbacks.


When it comes to the best dual flush toilet, make sure that it can effectively remove solid waste. Otherwise, you may not save any more money on your water bill than you would with a traditional toilet. Make sure it fits your space and contains all the features you require in a dual flush toilet. These are wonderful cost-saving devices provided you do your homework beforehand.
