Important Tips You Didn’t Know About Best Low-Flow Toilets

Buying a toilet has never been easy. With many designs and brands in the market today, it requires a really deep knowledge to get the effective toilet for your home use. But don't be a worry. Whether it is a two-piece toilet, one piece, or a low toilet, this guide will definitely let you have a perfect toilet to go with. Here is what you should always remember.

Know the Top Toilet Height for Your Needs

The ideal toilet height for your home use depends on your height, physical needs, and how you transfer on and off the toilet. Generally, a great toilet height should allow you to easily sit down, stand up, and of course, comfortably rest both your feet flat on the floor while using the toilet. To get the best height to think the following.

Best Height for Tall People

Taller people find standard-height toilets. This is a toilet with a toilet seat height of 15-16 inches high. This means that tall guys should go for a floor-mounted toilet that is labeled as “Comfort Height” as these usually have higher-than-average toilet seat heights (17 inches - 19 inches) when measured from floor to the toilet seat.

The ADA Height Toilets

The Americans with Disabilities Act Accessibility Guidelines (ADA) has recommendations on what height toilets should be installed for the general public. These include the toilet seat height ranges and also how many gallons of water per flush they should use. ADA designed toilets are often the middle edge for all heights.

Best Height for Shorter People

Anyone whose height is approximately 5 feet 4 inches tall or even less prefer standard-height toilets with a height of 15-16 inches high or less. Such a toilet allows them to rest their feet flat on the floor. Dangling feet are un-comfy and leave pain too.

Understand what to Consider When Buying a New Low-Flow Toilet?

From the top-rated low-flow toilet to the most exceptional flushing toilets, there are a number of tips that you must keep in mind when purchasing a toilet. These will give you chance to pick the right toilet for your use. They include :


Check out whether the toilet is worth to praise. At times I came across toilets that all they have is a water sense label, but in the real sense, they do not give the efficiency that I need for it to qualify as a right low-flow toilet. Toilets that come with warranty will give you some time to ascertain that they are water sense.


Performance is the real deal. High performing toilet is the one that gets all the waste down the drain and leaves the bowl clean. Clogging is the worst nightmare for any household. Simply it is very disgusting so make the right choice.


You need to check out for the price of the toilet too. The price can be deceptive. You might think that the highest price will guarantee you the top toilet. With my many years of experience in the field of toilets, I know without a doubt that is not always the case.


Usually, the determinant for the size of the toilet will be the available floor space. The installation should not tend to take all the space in the washroom. Size and height correlate and a height that feels comfortable are the best.

Keep a Keen Eye on User Reviews

You aren’t the first person to use these toilets. And even you will not be the last. So, it is always advisable to ask for a little lead whenever you feel lost. A five minutes browsing will give you enough toilet reviews to give guarantee you the best experience with your toilet. Therefore always take your time to look through what other users say for a first-hand experience.

Get the Right Design

You have a personal lifestyle, home design, décor, and style. It is only realistic that you get a design that compliments all these. You can always choose a number of designs including two-piece or one piece toilets. Better still you go for your favorite color and finally look out for the right shape (oval, round, or oblong) type of toilet too.

Availability of Replaceable Parts

It may not look like much but believe it or not your toilet could break down when you list expect it. Without the right accessory, you may have to live through that annoying unfixable problem. It could be a broken handle, damaged valve, cracked bowl, and many more. Having a toilet that you can find its accessories easily is always a wise decision. It will save you so much pain having to look through numerous shops.

Choose Great Brands

Yes. Brands do matter; and the best brands are determined by more specifically the user reviews, expert reviews, recommendations, and overall specific factors. Great brands come in term of design, quality, or sometimes pricing. It is very important that you know what you need and gives a well-known brand for the same a top spot when shopping around.

The Size of Your Room

Many people don't usually talk about this. But the truth is that some toilets require more space to install while others won't. So, the size of your toilet room should get a key consideration when buying a toilet. For a limited space you can always choose a round seat toilet. Oblong and oval toilets require more space and thus should have exactly that.

Other Factors

  • Wash down
  • Reliability
  • Warranty

Know the Right Toilet Water Conservations Tips

You don’t want so many bills bogging you down because of a toilet – sometimes it happens. High water bills are the one thing many toilet users cry for. Therefore it is important that you understand how to get the how to conserve the water. Here are a few tips to help.

Look at the Basic Construction/ Design

Toilets have two main basic constructions/ design namely one piece and two piece toilet. But it is how you set the design that helps you to conserve the water. Always measure a good "rough-in." This is the distance from the center of the toilet flange to the wall whose standard measurement is 12 inches (10 and 14 inches exist). This is the secret to low water bills always.

Get the High-Quality Toilet Flushing Options

There are four flushing options. They include eco-toilets flush, dual flush, pressure assisted flush, and single flush. Single flush is required to work at 1.6 gallons per flush. The dual flush should work at 1.28 gallons per flush (they need water sense technology). The pressure-assisted flush should be designed to use compressed air to aid in the flush. Keep an eye for these details if buying.

Understand the Standard Ratings

Standard ratings will easily let you determine a toilet that uses less water and one that doesn't. It borrows its concept from the simple fact that cheaper toilets may still need much more than just a single flush to get the job done. Maximum Performance Ratings take in all details including reviews to ensure a great toilet for maximum customer satisfaction always.

Frequently Asked Questions About Low-Flow Toilets

Like any other product, toilet consumers often ask a number of questions when buying their low-flow toilets. Here are some that you should keep in mind at the time of purchasing a low-flow toilet.

Does a Low-Flow Toilet work as Good as a Normal Toilet?

Here height and size of a toilet do matter. However, the performance of the toilet depends more on the design and the technologies used. Basically, height is simply meant for comfort and the size too. But a toilet with water sensor technology, whether normal/ standard or low will perform exactly the same as a low-flow toilet with the same technology.

Are Pricey Toilets Good Toilets for Use?

Not really. The price of a toilet is determined by a number of factors including design and structure. Two-piece toilets will cost less than a one-piece toilet. The type of hue a toilet has also played a key role. But in overall fact, there are some other low-cost toilets that would still perform as good as their pricey counterparts. It is always vital to keep this in mind.

Can a Low-Flow Toilet Last Longer than a Standard One?

Yes and No! How long your toilet will last depends on how well you take care of it. If you clean your toilet with a brush with metallic bristles, the truth is that your toilet will get scratched all over the place and in fact have a very poor face as opposed to one cleaned with a hard bristled brush. So always follow the proper care for your toilet.

Can I Install My Toilet Alone or Must I get Experts?

Toilets are not your everyday cup of coffee – they are not easy to install. In fact, one piece toilets are really hard to install and often very heavy too. If you don’t have the expertise to install a toilet, it is better you stay out of it and call in an expert to help. However, if you are professionally trained you can go ahead and do it with minimal help.

Why Is Water Sense Technology Very Important?

Water sense technology helps you to use minimal water to flush off both liquid and solid waste. This is very important as it helps you to keep your water bills pretty low. This technology helps toilets to use up to 20% water efficiency during flushes with the same high performance. This one equates to about 1.28 gallons of water per flush.

How Often Should I Clean My Low-Flow Toilet?

Cleaning your toilet depends on you. If you feel your toilet is dirty, then you should clean it immediately. However, you can always clean it after three days or even weekly. Better still you can make use of the modern automatic toilet cleaners that allow your toilet to remain clean with every flush that you take. This allows you to keep bacteria/ germs out.
