Best Low Flow Toilets

Toilets are important. Although we may not give them much thought, toilets are essential to our daily comfort and wellbeing. Toilets play an important role in establishing a more environmentally friendly society.

Some older toilets can use up to seven liters of water with each flush. That equates to billions of gallons of water that could be used elsewhere being wasted annually. Low-flow toilets, thankfully, are an easy answer to this issue.

Low-flow toilets use only 0.8 to 1.6 gallons of water per flush, which is better for the environment and your wallet. 

Additionally, several businesses have started producing these low-flow toilets because certain governments mandate them for new constructions. We have created a list of the best low flow toilets for you. So, let’s begin.

How Did We Make the List

Water conservation and functionality

The best low-flow toilets should work the same way as standard toilets while saving water. Unfortunately, not every low-flow toilet meets that requirement. Because of this, we searched for toilets that consumed less water and had the same flushing capabilities.

Quality materials

We looked for high-quality versions made to last because low-flow toilets can be a little more expensive than standard toilets. Every model on our list is constructed with high-quality components, most of which include warranties. All models on our list are excellent investments because of these attributes.

Ease of use

It might seem strange to choose toilets based on their “Ease of Use,” but we weren’t just considering everyday use. Additionally, we considered things like installation, upkeep, and cleaning.

The first low-flow toilet designs were not very good. Many lacked the flushing skills to clear the waste bowl and rinse it effectively. Because of this, we searched for contemporary designs that could continue to perform well throughout time.

Let’s begin with a traditional choice: the Kohler K-6669-0 Memoirs Toilet. This hybrid of the K-4434 tank and the K-5626 bowl resulted in one of the Memoirs Collections’ most popular models. It’s a charming piece that would look great in any modern home.

Details are one of the things that stand out most about the K-6669-0. Its molding-like details allow it to match the details of a modern home, allowing it to blend in nicely with most American homes. It was the perfect match for many homeowners’ home decor.

Despite its classic appearance, it does not appear to be out of date. Its concealed trap design adds a modern touch while making it very easy to clean. It also promises excellent results in terms of performance. It is outfitted with various technologies that make it powerful and effective when flushing.

It uses gravity to flush and an Aqua Piston canister for 360-degree water flow, which cleans the bowl’s walls and aids in flushing. Overall, this product is more than just a pretty toilet for your powder room. It’s also very functional and even pleasant to use.

Features

We feel something is missing when a toilet’s trapway is not skirted or concealed. They lose a few points for lack of style. The Memoirs provide a hidden trap by providing a smoother, more appealing surface. This style is known to be a little more expensive than standard traps, but we believe the extra cost is well worth it. After all, everyone wants a modern-looking bathroom.

The Kohler K-6669 receives a score of 1,000 g. This is powerful and at the top of the scale. So, this would be something to think about if you want a toilet that doesn’t get stuck up easily.

Perhaps more impressive than the above performance is its ability to use less, conservative amounts of water. With a 1.28 GPF rating, it complies with EPA WaterSense guidelines. Good news for people who want to save money on their water bills. You may also be eligible for rebates or vouchers in some states. Compared to the current 1.6-gallon toilet range, 1.28 gallons save an impressive 20%.

While it has all the functionality you would expect from a top toilet brand, you should be aware that it is slightly more expensive than average but still falls within the affordable mid-tier price range. However, at around $500, it may not be an option for those on a tight budget. And to them, we say keep an eye out for new reviews coming soon.

Pros
  • Trip lever with polished chrome on the left
  • Comfort height, two-piece, elongated, single-flush
  • From the collection of Memoirs
  • Simple to clean
  • Canister flushing avoids obstructions
Cons
  • Expensive
  • Single flush

Factors to Consider While Choosing the Best Low Flow Toilets

Factors to Consider While Choosing the Best Low Flow Toilets

Water use and certification

Make sure the low-flow toilet you’re buying has the WaterSense certification before you buy it. This indicates that it satisfies all criteria for becoming an environmentally friendly toilet. 

To determine whether a toilet satisfies its stringent requirements, WaterSense looks at how it flushes and how much water it uses each time. A toilet is sure to be a good option if it has the WaterSense seal of approval.

Toilet comfort and warranty

We probably spend longer than we would want to admit on the toilet. It just seems to reason that we would want it to be as comfortable as our favorite chair. Consider what height seems more comfortable for you. 

Taller toilets like the Kohler are preferable if you have problems standing up. They are ADA compliant and frequently referred to as comfort height toilets. A lower seat height is better if you have trouble with things going down.

This brings up the warranty, which is another thing. In terms of financial savings, a low-flow toilet takes a while to pay for itself. Therefore, it’s not something you typically intend to replace too frequently, just as you want your toilet to last for a long period when you get the best low flow toilet. A strong warranty offers you confidence that your goods are of high quality.

Noise level

Another thing to consider is noise, particularly if you plan to put the toilet next to your bedroom or the baby’s room. Fortunately, you can monitor the noise level using the unit’s flushing system. 

The best flushing toilets are typically gravity-flushed types since they flush quietly. Some units, however, have unique fill-valves that allow for a silent flush. Leaving that aside, you should think about flushing toilets that have a soft lid closure rather than one that slams shut.

Bowl appearance and material

Everyone naturally has unique tastes, preferences, and fashion sense, especially regarding something as straightforward as a toilet. Different materials and shapes are used to make toilets. 

Some toilets are fixed on the wall rather than sitting on the floor. All of these criteria should be considered when choosing the best low-flow toilet.

Type of toilet: one-piece vs. a two-piece

One-piece and two-piece toilets are the two types of toilets that are available. The primary distinction is rather obvious, but what does it mean (given that there are more than two parts to a toilet)? The tank is where there is a difference.

The tank and base of a one-piece toilet are one complete component. As the name suggests, a two-piece toilet has a separate tank and base as its two primary parts. It occasionally has a bigger tank than one-piece toilets, but they typically cost less.

Color options

Having a variety of color options is helpful when choosing the greatest low-flow toilet, even though this shouldn’t be a deal-breaker among the other toilet functions. While having a functional toilet is important, having a nice-looking bathroom is also important. 

There isn’t typically a flushing toilet that is best rated for its aesthetic, but it is preferable to get one that matches the design of your bathroom. You should consider the interior design of your bathrooms and the color possibilities. 

The top flushing toilets come in a variety of designs and decorations. Choose one that will fit your bathroom as a result. A modern piece, for example, won’t go well in an outdated, rustic bathroom. There are various styles to pick from, and your bathroom needs a toilet with a strong flush system that looks excellent.

Finding a quality toilet

Look for companies with a stellar track record and glowing customer testimonials. You should also look for a toilet with the best power-to-water ratio. In other words, using the least quantity of water while producing the maximum energy. These low-flow toilets can be identified by how their flushing systems are constructed. 

Check for features like pressured rims, wider flush valves, and jet siphons to improve power. Additionally, keep in mind that more power occasionally necessitates more water. If you prioritize flushing performance, you can wind up with a low-flow toilet that consumes more water than average, although still just 1.6 gallons.

Benefits of Low-Flow Toilet

Saves you money

Imagine having hundreds of additional dollars in your pocket annually. One of the main advantages of selecting the most recent low-flow toilets is that. Compared to conventional toilets, low-flow toilets are built with a smaller tank and a higher level of water efficiency.

The leading low-flow toilets consume just 1.6 gallons per flush as opposed to the 3.4 gallons used by conventional versions, saving you nearly two gallons of water per flush. This can result in hundreds of dollars in annual savings for homeowners with a large family residing in the house.

Use less water

Low-flow toilets utilize a quarter of the water that standard toilets do. Some high-efficiency toilets can use as little as 20% of the water flushed by a standard toilet, or even less when using the half flush option. Most low-flow versions use less than a quarter of this amount.

Since water conservation is one of the largest environmental problems of our time and is predicted to get worse in the years to come, this is extremely important. Each can make a difference by adopting more water-saving appliances at home, starting with our toilets.

Compact designs

Low flush toilets are now available in a variety of amazing designs. Various colors, bowl forms, seat shapes, and general styles will be available to select. Low flow toilets typically have smaller tanks than standard toilets, making them smaller overall. 

As a result, they may fit in small areas, free up room in larger bathrooms, and generally have a more contemporary, slimmer appearance.

Frequently Asked Questions

Why should I use a low-flow toilet?

Low-flow toilets use the least amount of water while providing a strong flush. As a result, they lower your water bill while also assisting in environmental preservation. Additionally, most low-flow toilets have contemporary designs that will give your bathroom a chic look.

Are low-flow toilets more prone to clogging?

It’s one of the main issues preventing manufacturers from reducing water use. Still, given that this norm has been in place for nearly 30 years, outdated prejudices no longer apply. Most of them develop innovative flushing techniques that increase the flow’s strength.

Some also create new surface types that are stain- and debris-resistant, which improve flow and reduce clogging. But that happens very infrequently with the models we looked at above. 

Should I choose a dual flush toilet or a single flush toilet?

These two flushing technologies are very efficient and make waste removal simple. But, if conserving water is your priority, a dual flush toilet is a superior option. 

The dual flush toilet allows you to choose between a partial or full flush, which ultimately helps you save water. With a single flush, this is not the case.

Do low-flush toilets cost a lot?

The price varies depending on the mechanism; gravity-assisted toilets cost almost twice as much as pressure-assisted versions.

Numerous local councils are providing refunds and incentives if you purchase a low-flow toilet as they work to cut water usage. Check with your local council, as this could make purchasing a low flush toilet much more affordable.

Is it possible to install a low-flow toilet yourself?

You might consider removing your old toilet and installing the new one yourself if you want to replace it with a low-flow one. Although it may seem straightforward, upgrading a toilet is time-consuming and deceptively complex.

Toilet removal and installation necessitate specialized tools and skills. So it’s best to leave it to the experts unless you’re an expert in this field and have your tools.

Conclusion

We think you now better understand the best low flow toilet and how to pick the ideal model for your house. You should be able to conserve water and lower your water bill with a decent low flow toilet. You should also consider other elements when choosing a low-flow toilet, including performance, comfort, ease of cleaning, and rough-in size. 

Because you will use the low flow toilet for a very long time, ensure it fulfills your needs. Don’t compromise because doing so will make you regret it later. 

We sincerely hope that you may now choose your next low flow toilet with confidence.
