Buying Guide of dual flush toilet

After reading the dual flush toilet reviews, you can easily understand that these bathroom accessories are manufactured to conserve water. But apart from ensuring less water consumption, there are some other factors that you should consider.

WaterSense certification: Most of the 2 stage flush toilet consumes low amount of water. But, it’s only fruitful if these fixtures are flushing effectively. It is where the problem lies. Some of the variants use less water, but their flushing performance is poor.

So, search for a toilet that has WaterSense or EPA certification. This label means that the toilet consumes less water but never degrades its flushing strength. Keep in mind that it’s not about the size of the cistern. Instead, we are talking about the number of flushes.

Some of the dual flush toilets waste as low as 0.8 GPF, but you have to flush them twice or thrice to get rid of all the waste. Such a bathroom fixture cannot conserve water. So, find something with WaterSense.

Comfort: Most of the top rated dual flush toilets are at least 16 inches tall. ADA suggests a sitting height of 17 inches. For added comfort, some of the models are built with a height of 18 inches. It’s one of the most important factors to check, especially if you are a senior citizen or tall individual.

Apart from the sitting height, it’s better to look at the shape as well. In the dual flush toilet reviews, you might have noticed that these units are available in multiple forms, including round, elongated, and square. Round models work great for compact spaces, but elongated ones are high on comfort.

Sound levels: Some of the 2 stage flush toilets quietly remove the waste, but others make resonant sounds. It’s not big trouble if you live alone. But, things are different in some instances.

For example, such noises can be disturbing if your baby is trying to sleep. Or your partner or any other family member is a light sleeper. Hence, investing in a silent bathroom accessory could be beneficial in such situations.

Maintenance: While reading the dual flush toilet reviews, you might have noticed that some of these models are available with a protection glaze. Such a layer protects the toilet from stains and bacteria to keep your bathroom hygienic. Moreover, it also reduces the cleaning frequency.

Apart from that, one-piece toilets are easy to clean. So, try investing in such a variant if you don’t clean the bathroom every other day. In addition, try something with a powerful flush. A forceful water flow also helps you to keep the toilet clean.



Now you know nine top rated dual flush toilets. Based on all the factors we discussed in the buying guide, Woodbridge T-0019 is the best dual flush toilet because of its powerful performance and comfortable built.

This model has a single-piece design, which means it’s easy to clean. In addition, this recommendation is available at a reasonable price tag.
