Best Tankless Toilet Buying Guides

Tankless toilets have increased in popularity in the past few years. Projecting a clean, contemporary appearance, they make any bathroom look classy and elegant. However, tankless toilets are not for everyone. Unlike most common toilets, these cost thousands of dollars and are usually found in higher-end homes, luxury apartments, condos, and commercial buildings.

If you are interested in buying this kind of toilet, the following best tankless toilet buying guide will be able to help you make a decision on which toilet to buy.

How does a tankless toilet work?

As the name implies, these toilets do not have an attached visible water tank, commonly found on a large number of toilets in use today. Instead of a water tank, tankless toilets use an integral electric pump that powers away waste material with the aid of a connection to a specialized water supply of the appropriate size hidden either inside the wall behind or through the floor.

When the tank is flushed, water is instantly replaced in the toilet bowl at a faster than average rate. Keep in mind that these toilets do not store water. Drainage of waste-water is removed from the bowl in the same fashion as the more traditional toilets with visible water tanks.

What are the different parts of a tankless toilet?

These toilets have fewer parts, which are a definite advantage. However, when repairs are needed, the required parts are expensive and hard to replace. It is advisable to have parts of a tankless toilet replaced by a qualified and licensed plumber should the need arise.

Attempting to replace parts on one of these toilets is difficult, and without the proper working knowledge of these toilets, it may cause irreversible damage. Integral parts of a tankless toilet require specialized tools to remove and install, which are expensive and traditionally not a part of the standard homeowner toolbox.

How to install a tankless toilet

Installing a tankless toilet is not for the average weekend do-it-yourselfer. It may be difficult to install and often require more than one person. As noted, these toilets are mounted directly to the wall, sitting on no base. These often use specialized mounting hardware that is enclosed in wall cavities. Depending on the manufacturer of your new tankless toilet, this mounting bracket often consists of steel plating of thicknesses of ½” or more.

In addition, these toilets operate on an incoming dedicated water supply line that is used to supply water to these toilets and no other bathroom fixtures. Sizing of this incoming water supply line is essential. Incorrect sizing will cause your new toilet not to work properly, leading to additional expense and possible replacement of the toilet that you just purchased.

Conserve energy, time, and a larger amount of frustrations and have your new tankless toilet installed by a licensed, professional plumber.

Common Problems With Tankless Toilets

These toilets have only a few parts, which is one of their most attractive features. The Flushometer, which controls the incoming water pressure, is an important part of these toilets. Designed and engineered to last a lifetime, the integral parts of these toilets seldom fail. It is the inadequate sizing of incoming and exiting water and drainage lines that appears to be the most common problems with these toilets.

Tankless toilet vs. tank toilet

There is no way to compare a tankless toilet to the more traditional toilet with a visible tank. Granted, there are toilets on the market today that appear to be tankless. However, they have the common water tank installed in wall cavities. These are not tankless toilets.

These toilets have only one major part, the toilet bowl itself, while the more common toilet has two major parts, the bowl, and the tank. If your new toilet has more than one major part, then it is indeed not a tankless toilet. Creative advertising and high-pitched marketing techniques often lead consumers into buying a toilet that is often less than expected.

With any product, regardless of where it is to be used in your home, there are advantages and disadvantages to consider. Such is the case with tankless toilets. One major advantage of a tankless toilet is the amount of water that is used per flush. Tankless toilets are environmentally friendly, streamlined, smaller with a zero-tolerance for continual running, after flushing.

Perhaps one of the major disadvantages of a tankless toilet is the electricity factor. Since these toilets operate on an electric pump, if your power goes out during a storm, your toilet will cease to operate as well.

Frequently Asked Questions (FAQs)

Purchasing a tankless toilet requires additional forethought and consideration. It costs significantly more than the traditional two-piece toilet, so questions are an ideal way to clarify and discover new information about your intended purchase. The following questions are provided to define some areas of concern addressed by prospective consumers clearly.

Q. We have many Kohler fixtures in our home and have come to rely on the quality of their products. Are their tankless toilets as reliable?

A. What can you say about a company that has not already been said or read? The Kohler K-5401-01 is a tankless toilet that is a symbol of all that this company stands for. If you are comfortable with their products, why change?

Q. Does any company make a tankless toilet in any other color besides white?

A. Since there are only a few companies that make these toilets, check their websites for other color selections. You may pay more for a different color, but the additional price may be more of what you are looking for.

Q. Are tankless toilets as hard to install as everyone is saying?

A. Yes, even harder. Unless you have many years of experience as a professional plumber, leave the installation of these to someone that can do the job right the first time.

Q. Why are tankless toilets so expensive?

A. Tankless toilets are designed like no other toilet on the market. With the latest in technology and design, these toilets are true marvels of engineering. Granted, they are expensive; however, as the demand for these toilets increases, you may see the price decrease.

Q. Where is the best place to buy a tankless toilet?

A. You can start by looking at the manufacturer’s website for the model that you are interested in. Some manufacturers offer discounts online. Amazon is also another good and reliable source to find the exact model you are looking for.


Tankless toilets add a touch of elegance to a bathroom in some of the most expensive properties throughout the world. These toilets are designed with features not found on the more traditional one- or two-piece toilets. Priced at more than three to four times the cost of the average installed toilet, these toilets are less affordable for those living on a limited building or remodeling budget.

From heated seats to automatic flushing, these space-saving toilets are thought to be the new trend in bathroom fixtures. Eliminating the often cumbersome and less attractive water tank, these toilets offer one-piece construction, providing a new, more contemporary look to a bathroom depicting the individual style of the homeowner.

Setting a new trend in bathroom fixtures, the tankless toilet is only the beginning of a new evolution in bathroom fixtures that will continue to change year after year.
