How to Pick the Right Dual Flush Toilet – Buying Guide

The whole focus of reading our best dual flush toilet reviews is to end up with the right one. But even if you read our reviews entirely, you may get a bit confused.

In this section, we want to help you get rid of that confusion. You’ll learn everything there’s to learn about dual-flush toilets and a bit more. So take a look at the array of factors you should look for when buying:

Flushing Power

Sure, the toilet comes with a dual-flush system. But how many gallons per flush are you using? Here, we recommend choosing wisely. That often means getting a rinsing flush that offers anywhere from 0.6 to 1.0 GPF. This amount of water should be enough to get rid of liquid residues.

But if you want to drain solid and substantial residues, then you’ll want no less than 1.0 GPF and up to 2.0 GPF. Anything within that range should remove solid remains with little effort.

Flushing Systems

Apart from the overall flushing power, you’ll want to consider the type of flush used. Here, you will often need to consider between gravity-powered or pressure-assisted flushes.

Sure enough, gravity-powered toilets are less common nowadays and less effective. Yet, they often make the toilet a lot more affordable than a pressure-assisted model.

But no matter what type of flush, you’ll want high-end flushing technology on the toilet. That’s why 360-degree tornado flushes and similar systems can also be super-helpful.

Flush Type

What type of flush mechanism does the toilet use? Here we recommend buttons over levers. Buttons are more straightforward to push and clean than levers. However, levers tend to be a bit more reliable and way cheaper.

Also, where is the flush button/lever located? The right position will help you flush more easily and hygienically. So be sure to have something that doesn’t make it harder or dirtier to do. A top-mounted flush is ideal for that.

Shape & Size

A toilet can be round or elongated. Some models are semi-elongated. The difference is that round models are usually smaller than elongated ones. While round bowls are between 16 and 17 inches, elongated ones are between 18 and 19 inches. A hybrid or semi-elongated toilet is typically 17.5 inches.

This difference in size also changes the price of the toilet. Round models are usually more affordable than elongated as well.

So if you have a small budget and a small bathroom, a round model may be your best bet. But if you prefer a more comfortable toilet and don’t care about spending a few extra bucks, then an elongated model will suffice.

One-Piece or Two-Piece

Apart from the size and shape, you need to consider whether the toilet is a one-piece model or at two-piece. Obviously, one-piece means you will have an easier time cleaning it and installing it. Yet, two-piece toilets are way more affordable and have bigger water tanks.

Styles & Designs

The design and color of the toilet will also tell you whether it matches well with your bathroom or not. Some toilets boast a modern design that looks awesome but will probably not match an old traditional bathroom. In contrast, you may find standard-looking models that fit anywhere with ease.

Don’t overlook the skirt design of the toilet, though. A fully-skirted trapway (bottom part of the toilet), will be easier to clean than a naked trapway.

Comfort Level & Toilet Height

Once you’ve figured out the flushing and design of the toilet, then consider the level of comfort it offers. Here, you will mostly need to look at the seat height. This is often between 15 and 20 inches. We highly recommend 16.5-inch Comfort Height toilets as the go-to choice.

Lid Design & Features

Lastly, consider whether the lid is standard, comes with extra features like heating or padding, or eventually offers a soft-closing system. The right seat can have a significant impact on how well you feel when using the toilet.

And if you want an even better product, make sure the toilet comes with a lid and seat. Some toilets do not, and that’s okay. But if you can get one with a seat, then you’ll save a few bucks as well as some time.

Frequently Asked Questions (FAQs)

Once you’re done going through our reviews and learning with our buying guide, then you’re ready to tackle this section. Here, we want to answer some common questions users have. This could be either doubts you have about dual-flush toilets or general questions that we didn’t answer before.

Here we answer them all:

What is a dual flush toilet exactly?

Most toilets use a single-flush system, meaning you push a button or pull a lever, and the water drains through the trapway. A dual-flush system does the same, but instead of draining at once, you can decide whether you want a smaller delivery. This will help you save a lot of water over time.

How does a dual flush toilet work?

The process is simple. You push a button or pull a lever that activates the flush valve. Then the tank opens up according to what flush you activated. The water goes from the tank to the bowl, and the siphoning system makes sure everything goes down the train.

Are dual flush better than single flush toilets?

It depends on your demands. But we can safely say that a dual-flush toilet may prevent a lot of water wastage. At the same time, they make it easier to flush everything more effectively. A single-flush toilet may not offer the chance to regulate water use or flush effectively when needed.

Are dual flush toilets worth it?

Yes, they totally are. Dual-flush toilets will save you a lot of money over the long term, will make you feel better about your water use, and eventually get rid of residues effectively.

What happens if you push both buttons on a dual flush toilet?

The toilet will flush as it would typically do when you push the large one. This happens because the large button or lever will immediately open the whole tank flush valve. So it doesn’t matter if you push the large button alone or with the small one. Either way, the toilet will flush at its highest rate.

Conclusion

So, are you ready to get a new toilet? Then don’t hesitate and pick the best dual flush toilet for your needs.

There are fantastic models on this list to pick from, so it is time for you to choose. Remember to use our buying guide for help. It will tell you everything you need to consider.

And if you’re still doubtful, revisit our FAQ section. It will remove your confusions.

So, what else do you need? The ideal dual-flush toilet is waiting for you.
