Benefits of Tankless Toilet

Benefits of Tankless Toilet


The size of a tankless toilet is considerably smaller than that of a conventional toilet with a cistern or tank. Imagine it without the tank to visualize how cool it would appear. Because there is no tank, a tankless toilet can be installed practically anywhere.

Of course, the fixture would need to be connected to the plumbing system, and you wouldn’t just put a toilet anywhere. However, the fact that you do not need to account for a certain location for the tank allows you to experiment with the design and layout of the bathroom.


The tankless toilet is unquestionably more attractive and trendy than a standard toilet. If not the aesthetics of the whole house, at the very least, it will improve the look of your bathroom.

Even while it may be too soon to tell whether or not installing a tankless toilet would have a direct effect on the price of your home, there is no question that it will make an impression on potential buyers if you ever decide to put your house up for sale.

Helps in water conservation

The majority of homeowners are seeking strategies to conserve water in their homes. This is because the majority of them have been paying large water bills at the end of each month. The good news is that, in the long run, this toilet can help you save more water. This is because these toilets do not keep excess water in storage.

The tanks can contain up to three gallons of water if you have a regular toilet. You can bet that if there are more toilets like this, more water will be saved. If you have more people in your house, this water is more likely to be used. As a result, purchasing a tankless toilet is recommended.

Fewer issues

It’s natural for a toilet to have issues every now and again. Traditional toilets, on the other hand, have a lot of disadvantages as compared to tankless toilets. Occasionally, the valves will fail, and so on.

It’s possible that the inlets will need to be serviced from time to time. You may end up causing additional damage if you attempt to repair these parts on your own. Consequently, you should select the tankless toilet, as these issues will be rare. This may provide you with some relief.

No leaks

Tankless toilets don’t leak much. As a result, they are more eco-friendly. In most versions, the water supply pipes are usually located under the flow or within the wall. Compared to the traditional ones, they are a superior choice.

Cleaner toilets

Because of the high water pressure, this toilet can flush more effectively than a tank toilet. As a result, your toilet will remain cleaner for a longer period. While a tankless system has its drawbacks, it is not altogether a bad solution.

More efficient

It doesn’t take long for the bowl to fill up because these toilets often use an electric pump. If you have a lot of people in your house, this toilet can be quite useful because it can serve a lot of people in a short amount of time.

What is a Tankless Toilet

Factors to Consider While Buying Tankless Toilet

Physical measurements

Length and height are the two primary factors to consider when purchasing a tankless toilet. A toilet seat’s length is normally around 16 inches, which is considered ideal by most industry standards. However, if the toilet is elongated, you should seek a model with an 18-inch-long seat, which is usually more comfortable but slightly more expensive.

Comfortable units normally have a height of at least 17 inches from the floor to the rim. These are ideal for seniors or people who have back problems. The standard units are slightly shorter, standing 15-16 inches tall.

You should also check whether the dimensions supplied are with or without the seat. You don’t want to purchase a toilet that looks to be on the taller side only to find out later that you need a seat riser, which could involve additional time and money to install.

Mounting position

There are mainly two types of tankless toilets. A cistern or a pressurized tank can be installed behind the wall. You can mount either version on the wall or the floor, depending on your bathroom. Wall-mounted units give the illusion of more space in the bathroom, but they need to be reinforced with brackets.

Floor-mounted toilets can sometimes cause problems, such as debris accumulating between the commode and the wall that you can’t reach. Furthermore, some toilets have visible plumbing, which might detract from the overall bathroom appearance.

Power supply

Once a valve has been opened after the lever has been pressed to flush, tank toilets rely on gravity. A tankless toilet, on the other hand, flushes the water using an electric pump rather than gravity and air pressure.

Electric wires are used to build tankless toilets. If you don’t have a toilet that can flush both with and without power, you won’t be able to flush it when the power goes out. These toilets require a constant source of energy from the house. Also, unless you’re handy, hiding the electric pump and connecting to the home’s power source could be a challenging task.

Bowl shape

Bowls are generally divided into two types: round and elongated. Bowls with a round form are smaller than those with an extended shape. So, if you have a limited amount of space or need to save space, a round-shaped bowl is preferred, but an elongated form bowl is considered as more comfortable.

Water supply

A tankless toilet is one that does not have a tank of water waiting to spill into the toilet bowl. When a flushometer is engaged, a tankless toilet is directly connected to a water supply and receives its flushing water. 

To clean the waste in the bowl, tankless toilets require considerable water pressure. Many private residences lack sufficient water pressure to flush effectively, necessitating the use of an electric pump to provide additional power.

Flushing power

Many tankless toilets have a tank that has been modified to make them look like they don’t have one. Macerator pumps are normally hidden behind a wall. However, they are also used in some toilets. Depending on the design of its tank, your toilet’s flushing may utilize more or less water, resulting in increased efficiency but possibly diminished flushing force.

If the intake is large, it will let more water enter through, resulting in faster flushing. For added power, you might want to select toilets with pressured rims. These sorts of commodes have specific markings that indicate their GPF rating. If it has Gmax, for example, it signifies 1.6 GPF regardless of the model.

Difference Between Tank and Tankless Toilet

Difference Between Tank and Tankless Toilet

Flushing systems

The flushing system is arguably the most noticeable distinction between tankless and tank toilets. Gravity powers the flushing of tank toilets. The water is pumped into a bowl, where a siphon is engaged to suck the water, solid waste, and liquid waste from the bowl into your home’s plumbing system. Thanks to gravity, a tank toilet’s flushing system can operate with a low water pressure of 10 PSI. 

On the other hand, tankless toilets use high-pressured water to drain waste from your toilet quickly and effectively. An electric pump creates high pressure by rapidly emptying the waste from the bowl, leaving a sparkling clean bowl behind. 

Electric pumps are only useful when the water pressure is low. You may not require an electric pump or other mechanical assistance if you already have adequate water pressure.

Water consumption rate

Traditional tank-style toilets from the 1980s consumed approximately 3.5 gallons per flush, which is more than twice the permitted 1.6 GPF water consumption rate. For the early toilet users, that was a complete waste of water.

While both conventional and tankless toilets are required by law to use less than 1.6 GPF, tankless toilets have utilized less. Some tank-style toilets require you to flush twice before the waste is completely gone due to their ineffectiveness. This results in a higher water bill at the end of each month.

On the other hand, tankless toilets can use as little as 1.0 gallons per flush. And, with their strong flush, you can always rely on just one flush to do the job.


Tank toilets must be installed on the floor since there is no other option. It also has a predetermined height. Tankless toilets can be mounted on the floor or on the wall. Tankless tanks can be adjusted in height when mounted in a mall.

Pipe installation

Tankless toilet pipes are located inside the wall, whereas tank toilet pipes are installed beneath the floor. As a result, tankless toilets are extremely unlikely to produce leaks.
