The 7 Best One Piece Toilets Reviews in 2020

Toilets are an essential part of your home; some houses have one toilet while others have more. It is undoubtedly a major aspect of your house and needs your attention. Toilets last for years, but when they do start to have problems, it’s best to address them right away. After all, it’s easier now more than ever to buy a toilet. You don’t need to check out one home improvement store after another. Just go online, read reviews, and buy the toilet that’s best for your needs.

If you have ordered toilets online, you would know that there are a lot of factors to consider when choosing your toilet. You would want a nice-looking toilet that is easy to install and fits perfectly in your bathrooms. You would also want the toilet to be comfortable to use and easy to clean. It should be an excellent water-saver, too, so you won’t get hit by huge water bills every month. Getting all these features in a single toilet may prove difficult especially if you are ordering the older two-piece toilet models.

You can save yourself the trouble of a prolonged search by buying a one-piece toilet. They are more compact, making them easier to transport and clean. One major drawback to ordering a two-piece toilet is the fact that the two parts sometimes arrive separately, which can be up to a week. This affects your installation plans, as it is difficult to plan for the installation when the two pieces are not together. However, you will not have this problem with a toilet.

We have put together a list of the 7 best one-piece toilets on the market today to make your choice an easier one.

Best One-Piece Toilets Buying Guide

Picking a toilet (or two) for your home is one decision that you would have to make at some point. It is crucial that you get this decision right the first time, so as to make every visit to the bathroom a relaxing and comfortable one. Here are some things you should consider before choosing a one-piece toilet for your bathroom:


The size of your bathroom determines the size of the toilet you should buy. If you have a very spacious bathroom, the size of the toilet is of little consequence. When space is at a premium, however, it is very important to put the toilet size first. Aside from its fit, the size of the toilet also affects its portability and to a degree, how easy it is to clean.


Whichever toilet you decide to get, always remember that you will be stuck with it for several years. You should make sure, therefore, that the toilet you choose will be easy and comfortable to use. Different features affect how comfortable a toilet is. The height of the seat, how easy it is to use and clean, and the ease of installation are some of the things to consider.

Apart from the comfort offered by the toilet, one other essential thing to look at is the overall comfort in the bathroom. A toilet that fits perfectly into your bathroom increases the total comfort you get from using it.

Flushing System

There are many flushing system options on the market, so selecting the right one may prove to be a little tricky. It is reasonable to expect that some of these flushing systems are not as good as others. The minimum requirement though is that the toilet should be able to handle any waste.

The flushing system used by a toilet sometimes determines how efficient it is in disposing of waste. The G-Max, Double Cyclone, and the Siphonic Dual Flush systems are some of the most effective technologies on the market. Make sure you confirm the flushing ability of the toilet before purchasing it.


Your budget is one of the biggest determining factors if you want to purchase a one-piece toilet or not. No matter how good a fit a toilet is if the price is beyond your budget, there is no way to get it. Most people believe that its cost defines the quality of a product. While this may hold true sometimes, you can still get the perfect toilet at a reasonable price.

Many low-cost toilets are efficient and durable, so no matter what your budget is, you can get a toilet that fits right into your bathroom. Of course, this is not an issue if you plan to spare no cost, in which case you have to consider other factors first before making your decision.

Frequently Asked Questions

They are becoming more popular nowadays. They fit even in small bathrooms, are easy to clean, and look great. Check out these frequently asked questions about this type of toilet:

1. What are the advantages of one-piece toilets over two-piece toilets?

Some of the benefits you will get from using a one-piece over a two-piece toilet include:

  • Installation – One-piece toilets are generally easier to install than two-piece toilets. This is mainly because they have fewer parts to install.
  • Size – Most toilets are a bit smaller than two-piece toilets because of the compact nature of the single unit. This makes them excellent choices for small bathrooms.
  • Cleaning – The skirted bowl that is featured in toilets covers many gaps that are found in standard toilets. These gaps are usually home to dirt, bacteria, and dust but the smooth surface of the one-piece toilet prevents their buildup.
  • Durability – It is generally believed that the fewer the parts equipment has, the easier it is to maintain, and the higher the durability. One-piece toilets are one piece of ceramic, which means they have fewer elements exposed to moisture and other factors that may cause damage. This makes them generally more durable than two-piece toilets.

2. Is there any disadvantage in using a one-piece toilet?

One-piece toilets are preferred to two-piece toilets because of a number of reasons. However, there is one significant disadvantage that one-piece toilets have over two-piece toilets, and that is the price. One-piece toilets generally cost more than two-piece toilets because of their more robust construction. The durability and look of one-piece toilets also make them more expensive.

3. How can I properly take care of my one-piece toilet?

It is not enough to buy a toilet with the best available specifications, as without proper maintenance, it may not perform as well as expected. A toilet that is properly maintained will last longer than one that is not adequately maintained. Proper maintenance procedures must be carried so that your toilet will remain in good condition for a long time. Some of the ways you can take care of your one-piece toilet include:

  • Disinfect the toilet – It is vital that you disinfect your toilet regularly to stop any growth of bacteria. Many products can be used for disinfecting the toilet, and most of them are readily available.
  • Prevent stains caused by hard water – Hard water is known to cause a stain on the surface of the toilet, so you should deal with the stain promptly. You can use vinegar to remove the stains.
  • The buildup of calcium and lime – It is common to find an accumulation of lime and calcium on your toilet over time. This can affect the longevity of your toilet as it starts to affect the finish of the toilet. Get a cleaning product that will help remove this buildup of lime and calcium.


Selecting a toilet is not a decision you should rush into because the type of toilet you choose will define your long-term bathroom experience. You should put enough effort into getting the toilet that is most comfortable and fits best into your bathroom.

They are an excellent choice for several reasons. They are compact and small, making them suitable for small bathrooms. They are also easy to install and maintain.

  1. My home is quite old, and some of the features reflect its age. One of those features is the toilet in my guest bathroom, and I think that it’s finally time I get an upgrade. Thanks for pointing out that if you get a water efficient one then you can use only 1.28 gallons per flush as opposed to the typical 1.6 gallons. I’ll have to try to get an efficient one as I look for a toilet replacement.
