Best Dual Flush Toilet 2020 Review & Guide

Compared to a single flush toilet where you flush a set amount of water every time, a dual flush toilet gives you the option to use only the appropriate amount of water.

Since the toilet is usually the biggest consumer of water in a household, it is a wise decision to get one where you can control the flush volume. In this article, you will see the 10 best dual flush toilets with outstanding reviews from users.

What Are Dual Flush Toilets and Why Should You Get One?

Dual flush toilets have two flush options you can press (usually on one big flush button). One of those flushes a huge volume of water, while the other releases a small amount. It gives you control of how much water to flush after using the toilet.

The half-flush mechanism is used for liquid waste, while the full-flush is for solid waste. Dual-flush toilets let you flush a smaller amount of water when possible; that way, you save water throughout the day.

A partial flush uses fifty percent less water than a full flush. An average dual flush toilet uses about 1.28 gallons per flush (GPF), the minimum standard for a WaterSense certification (EPA). Some toilet brands even make 0.9 GPF possible! Compared to a single-flush toilet, which uses 3.5 gallons of water per flush, a dual-flush toilet uses way less than that.

Dual-flush toilets are water-efficient, and with them, you can save up to 4,000 gallons of water per year (for one person).

Types of Dual Flush Toilets

One-piece toilets

Exactly as the name suggests, a one-piece toilet is a singular unit containing all working parts. If you want a simpler, smaller toilet, go for a one-piece. The fact that it’s only one piece eliminates the chances of dirt buildup on deep hideaways and recesses.

Two-piece toilets

Two-piece toilets are more common. These are toilets with a separate bowl and tank linked into one functioning toilet.

Wall-mount toilets

A wall mounted toilet has its water tank installed in the bathroom wall. To successfully get one of these working, you first need to readjust your plumbing system.

How to Pick the Right Dual Flush Toilet

Here are some tips on how to choose the perfect dual flush toilet. Every toilet is different, and there is one that will suit your needs! Consider these when sorting through a long list of potential dual flush toilet picks.

Appearance

A toilet needs to be attractive, but it also needs to match your bathroom interior. You have the option of an elongated vs. rounded toilet bowl and take into consideration angular vs. curved lines of your bathroom decor. Round toilet bowls are ideal for smaller spaces since they’re more compact, while elongated toilet bowls give you a more comfortable seating experience.

Dimensions

Aside from the dual-flush toilet’s shape, you have to consider the seat height too. ADA-compliance is always a welcome feature because it’s generally comfortable even for the elderly and people with disabilities.

Water consumption

The flow rate is also an important consideration. For solid waste, most dual-flush models use a 1.6 GPM flow rate. It’s always better if you can find a toilet that uses even less than that – it would let you increase your water savings even more.

Flushing mechanism

Old toilets use the flap valve as the flushing mechanism. However, if you want a toilet that conserves water, it’s best to look for one with a siphon system.

Typically, there are two flushing structures: gravity flush and pressure-assisted system. A pressure-assisted flush system utilizes pressurized air to force the water into the bowl. This flush system is more expensive (and results in a louder flush too) since it requires more sucking power, but it is more resourceful since it uses less water.

Gravity flush is quieter and more common in home bathrooms. A flush valve relies on gravity by producing flushing pressure from water weight. The waste travels through an S-shaped trap way, and then the siphoning system completely flushes it.

The appearance of the flush actuator in a dual-flush toilet can be traditional or modern. The toilet can have knobs, buttons, or levers for the flushing control, and it’s up to you which one is the most comfortable to use. Most people prefer handles or knobs over buttons because they like using free space on top of the tank to store things.

Features to Consider When Buying a Dual Flush Toilet

Toilet construction and material

Toilets do not always have to be plain white oval seats. There are lots of attractive options out there for style, color, and finish! You can opt for a modern, sleek look or a more interesting color. Toilet seats can vary in construction: wood, plastic, polypropylene, or vinyl. They can be cushioned, be made slam-free, or slow-closing. You can add a seat warmer, water stream warmer, and deodorizer to your toilet too.

Ease of use

Dual flush buttons on toilets are as easy as controls can get. Anyone can use them properly as long as they’re informed of the dual flush toilet’s water-saving capabilities.

To keep your dual flush toilet’s flushing technology working well for long term use, always make sure to maintain an adequate water level, prevent congestion, and check the flapper and valves regularly. To get rid of mineral deposits on your toilet, you need a simple vinegar soak.

Warranty

Dual flush toilets are a relatively recent innovation, which means that they’re well-researched and are guaranteed high-quality performance. Many companies offer at least one year of limited warranty for their products. Some provide more than that, but at an additional cost.

The warranty is a mark of quality. It’s best to buy from reputable brands, such as the ones we’ve listed below!
