Best Dual Flush Toilets – Buying Guide

There are several points to consider when choosing a 2 flush toilet. We cannot say that there’s a single best dual flush toilet for everyone, instead, you’ll have to find the one for you by looking at the features that match your individual requirements. Know that we relied heavily on field-testing and original user experience data plus information shared at the manufacturer’s site to trace out the pros and cons of duo flush systems.

So, before we get to the detailed analysis, let’s get to know the terms used and the common aspects of dual flush toilets.

1. Type

Most toilets come in two majo categories: one-piece toilet and two-piece toilet

The two-piece has been around for a long time. The bowl and the tank come separately in this type and so they have to be joined together. Most people prefer them because it is a cheaper option.

The one-piece dual flush system design comes in different designs. It is a whole unit together, that is the bowl and the tank. So you don’t have to attach anything. What most people like about it is that there is no seam between the tank and the bowl, therefore fewer bacteria and it is much easier to clean.

You may have of some few misconceptions about the single toilet. Some say that when one part malfunctions, then it means the whole system is useless. But isn’t that the same thing that will happen to the two-piece? When going for any of the above types, consider who will use the toilet, based on that choose the size.

Another thing is that single piece is good for shipping since it comes in one box while the other one may incur a few complications as different parts are shipped differently. Also, they can be transported in different time intervals.

And even though the single piece is modern and preferred the most, it can never beat the two-piece when it comes to price.

2. Configuration

As seen above, the two-piece toilet comes with separate pieces but the one-piece comes as a whole unit. So installing a two-piece can be a bit complicated. It can be simple to move this one, but you need to have it unbolted then bolted.

3. Size & shape

Generally, toilet bowls come in two shapes, elongated and round. Elongated are rectangular or oval in shape while the round ones are circular. Elongated bowls are two inches longer than the circular bowls. For the size, elongated ones measure 18 to 19 inches long while the circular is 16 to 17 inches.

Round bowls are a space saver and perfect for a small bathroom since they require a limited amount of space. They are also cheaper than the elongated. The latter is the most comfortable and a bit expensive. You may also find hybrid bowls which are a combination of the above shapes. They offer the most comfort.

4. Flushing system

One part of the entire household that uses the most gallons of water is a flush toilet – not the kitchen nor the shower. And when you are living with a couple of people in the house, then what is the results? Waste of water and a crazy high water bill. However, that can be reduced to a significant degree by using a dual flush pressure assist toilet.

The flushing system will depend on personal interest and the options are many. A button is more hygienic than one with a knob. Up flush toilets come with top buttons. But a knob will be better if you store things on top of your tank.

You may also consider the toilet’s trap way and the valve flapper. The larger these are the easier it will be to clean and the fewer the clogs. You can keep a toilet repair kit to fix any problem happening to the flushing mechanism.

5. Design & style

The customization of your toilet will also depend on your preference. There are so many different designs and it is up to you to find the one that suits you most. For instance, you can go for a tankless toilet. This will require a bit of expertise to install it near an outlet and plumbing. You can decide to fit it in near a wall or let the water pipes be underneath the toilet.

You can also find a flush on top designs that flaunt modern sleek or a classic porcelain design. A better way to go about this is by looking at your bathroom décor. You can then look at the size and space, angles and lines, color, among many more.

Is your bathroom a traditional look, contemporary or transitional, or is it modern? For a traditional style, there are options for that. You’ll find that a two-piece work well with this look.

Whether you want the toilet to be at the corner, near the sink, center or just by the door, it is all up to you. What about color? Well, many toilets are still in white but there other options like peach and glacier blue. Remember to pick a color that is likely to stay in style and one that suits you.

6. Comfort & durability

You probably are going to spend a couple of minutes for number two, so you want a toilet that has the maximum comfort. And since we know most people nowadays play mobile games while sitting on the toilet, it’s wise to get a comfortable dual commode. Some prefer a taller toilet which is about 15 inches from the floor with a seat ring of a half or one.

Choose a shorter model if you have just completed potty training on a toddler or if you are planning to teach them on the toilet. So when getting a toilet, make sure to check with the people living in the household.

A one piece toilet has high durability since it doesn’t have a separate part and does not allow modular attachments. It also has no out-leaking problems. But since a two-piece comes with separate parts, its durability lessens a little bit. The lesser the connecting parts, the more the reliability. Moreover, the very reason it’s called ‘dual’ flush system is it offers two different options for flushing– half flush and full flush. Get to know which button to push based on your requirement.

7. Warranty coverage

Most of these toilets are really expensive though you have to ensure that they have a warranty. And no matter what you spend, it is wiser to get a model that is covered for a long time. Even though some of these manufacturers offer generous coverage, be a clever buyer and check on the warrant first so you don’t have to worry about replacements.

8. Price

How much are you willing to spend on the flush toilet? Are you going to install it on your own or will you require an expert? These are just some of the few things you’ll need to look at. We’ve already seen that the one-piece designs are a bit expensive than the two-piece due to its many advantages.

Other than that, the two-piece, though highly competing with the single unit is not going anywhere soon as it wins most consumers. Depending on what you have, remember to calculate all the costs including buying, shipping, and installation. Another thing, the higher the comfort, durability, and quality feature, the higher the price.

Why switch to a dual flush toilet?

We’ve all been in that awkward situation, and to make matters worse, you don’t want the owner of the house to know the kind of mess you left. I’ve even heard of people saying that they cannot go to someone else’s toilet.

If everyone switches to a dual flush system, we may not be doing the environment a favor. So, why are people falling in love with this toilet?

First, you can help reduce the climate change footprints without affecting your household hygiene buy installing this system. This is a better alternative to composting toilets that don’t need water at all, but most people don’t like the cleaning part. Don’t worry about flushing multiple times. In fact, you have complete control over the amount of water the toilet requires, the mechanism is water-efficient in operation. You can also adjust the flushing mechanism if you want.

Second, some are a bit costly, but the good part is you get to reduce your water bill since you are already saving water.

No home can afford to miss out on this important opportunity. And with the ever-changing trends in lifestyle and fashion, these water closets (WC) are also bought for their low water consumption and aesthetic value.
