Buying Guide: Factors to Consider When Going for a Tankless Floor Mounted Toilet

Whether you are trying to save space or incorporate modern toilets with a minimalistic design into your building, there are some crucial factors to consider when going for a tankless floor-mounted toilet. These toilets come in various styles, sizes, and weights, and there is no one-size-fits-all toilet type. You have to consider which one would work excellently in your bathroom. Let’s look at some factors to consider when buying one of these models.


It is no gainsaying that tankless toilets are usually more expensive than conventional toilets. Well, that may be true when you’re paying upfront, but if you consider it as a long-term investment, you discover it pays off long-term. Families with many members will benefit from using a floor-mounted toilet model, as it considerably reduces the amount spent on water bills.

Installation Requirements

Tankless toilets come with demanding installation requirements, unlike plumbing-less toilets. As they require concentrated water pressure to function effectively, these toilets are mostly used in large public and commercial buildings which have the capacity to support them. A lot of residential buildings simply do not meet the right plumbing requirements to have one installed. 

Getting tankless toilets without the appropriate plumbing requirements can leave you and your house with leaks, damaged pipes, or even worse. 

Make sure to check with a professional plumber before attempting to buy the tankless models. Also, to avoid complications in the future, the installment of a tankless toilet should only be done by a professional.

Power Outages

Suppose you live in an area that experiences storms or other natural events that might cause power outages, you should weigh your options carefully before opting for a tankless floor-mounted toilet.

Since these toilets rely heavily on electric pumps to function, it could spell real trouble for you if there is a power outage for an extended period.


Before buying a tankless model, one question you should answer is—what do I need this toilet for? You can use it to save space in a tight bathroom or for a camping trip in recreational vehicles

Still, many people appreciate the model for its minimalistic design and aesthetic appeal, and others point to the toilet’s design to be ideal for physically challenged individuals. Whatever your reasons are, there is sure to be one model that suits your preference in the picks above.

Floor Mounted Toilet Vs. Wall Hung Toilets

Toilets are usually not the first thing that comes to your mind when thinking about a house, but the truth is that no home or bathroom is complete without a toilet. With the growing popularity of tankless toilets, whether to go for floor-mounted or wall-hung models depends on many factors. There are a couple of factors to look at before deciding which to go for. Here, we take a look at some of them.

Wall-hung toilet design

One of the first things you are looking at when going for one of these tankless toilet models is to save space. In this area, the wall-hung model slightly edges it out. Technically, the difference in size between floor and wall toilets is usually insignificant, but because the wall-hung models have their tanks installed in the wall, they save that extra space.

In particular tight spaces, it is usually challenging to meet building requirements when installing a floor-mounted toilet. But this hurdle is eliminated with the wall models, as when compared to their floor counterparts, they can save an average of 10 inches. 

Additionally, since the bowl of wall-hung toilets can be positioned several inches off the ground, more space can be created, and cleaning the toilet area generally becomes more straightforward.


One vital factor to consider when installing toilets, in general, is the installation part. Incorrect installations have the potential to cause significant problems in the future. In the case of tankless toilets, the floor-mounted toilet is generally easier to install. 

Wall-hung models require more time, equipment, expertise, and advanced plumbing. Also, wall hung toilets cost more money to install since the wall would have to be removed and reinforced after installation. Whether you are going for a wall-hung model or the floor-mounted version, it is ideal to hire only professional plumbers for the installation.


In terms of cleaning, wall-hung toilets come out on top. They are easier to clean due to two factors. First, since the base of wall-hung models does not touch the ground, space underneath is easy to reach and clean. Also, as the tank is installed in the wall, there are no crevices or tight corners to clean, and dirt or dust has nowhere to pile up. There is a greater area to clean with floor-mounted models, and dust can accumulate around the toilet’s base.


Both the wall-hung and floor-mounted toilet models have modern and minimalistic designs, and it is only a matter of personal aesthetics and style when making a choice. Different manufacturers have introduced innovative designs that are pleasing to the eyes and serve particular purposes. 


Floor mounted toilets come with a fixed height, and they cannot be adjusted and must conform to the existing shape of the bathroom. On the other hand, the models that can be mounted on the wall are more flexible and can be adjusted up to 19 inches off the ground. The standard installation height is 15 inches, but disabled and physically challenged individuals might favor a higher seat to ease the process of sitting and standing up.


Even the best of toilets will need repairs after some time, and if you end up getting a good toilet, that may not be too often. While you might think that floor-mounted toilets are generally more accessible to fix than wall-hung models, that is not always the case. However, some models allow easy access to the tanks without a lot of tearing down and reinforcement.

Tips for Getting the Best Out of Your Tankless Floor Mounted Toilet

While floor-mounted toilets with no tanks do not have as many problems as many conventional toilets, it is still essential to take proper care of your toilet. Follow these tips to get the best out of your tankless models.

Dispose Properly 

An obvious maintenance tip to follow is correct disposal. Flush only toilet paper and human waste down the toilet drain. Diapers, paper towels, cotton swabs, and feminine products clog toilets faster, so avoid passing them down the drain.

No Harsh Chemical Cleaners

Avoid using harsh chemicals to unclog or clean your toilet. Even though they unclog the toilets, they are harmful to pipes and could damage the pipes if used frequently.

Maintenance Checks

It is vital to schedule periodic checks to ensure your toilet is in good condition. Even though there is no problem visible to the naked eyes, toilets need to undergo routine checks to forestall potential problems. It is necessary to check your toilet at least once a year. Professional plumbers can detect minor issues or even help improve the functions of the toilet. 


How Does A Tankless Toilet Work?

A tankless toilet does not utilize water tanks like conventional toilets. Instead, it relies on a pump that has enough pressure to push waste down the drainage system.

Can I Put a Tankless Toilet in My Home?

Yes, tankless toilets can fit into almost any space, and they would look great in your home.

How Much Gallons of Water Do Tankless Toilets Use?

Most tankless toilets use as little as 1.6 gallons of water per flush, and newer models have reduced that to 1 gallon per flush.

Wrapping Up

By now, you should know more about tankless floor-mounted toilets and able to make informed decisions about which one best suits your style and space. Overall, all the toilets listed here are excellent options, and your choice boils down to personal choice and budget.

If we had to recommend just one of these toilets to you, our pick would be the Toto Neorest 700h. If money is not an issue and you are willing to dole out the cash for a quality experience, this toilet is the ideal option since the features and performance are top-notch. However, if that model is beyond your budget, then the Saniflo Sanicompact is an excellent alternative.
