Are you looking for a compact, fashionable, and economical toilet seat that doesn’t take up so much space and is easy to install? Then you need a tankless toilet.
A tankless toilet does not use a tank of water for flushing. Instead, they are a one-piece unit, connected directly to a water supply line that provides a measured high-pressure flow of water for every flush. Most models are a hybrid washlet (bidet) and toilet unit, the washlet utilizes the constant high-pressure water flow for effective cleansing. Since they are one piece and do not have a tank, they are easier to install and maintain.
Most of the tankless toilet models only use the force of water to flush, however, in high rises or when connected to a low force water supply, pumps are added to increase their effectivity. Since standard toilets use as low as 10psi per flush and are tank based, they cannot be combined with a washlet (bidet).

Price, Location, Space, and Comfort
While you might expect tankless toilets to be installed inexpensive homes due to their price, you will find many models installed in small homes and high rises. Commercial tankless toilets are one of the main features in the city of New York, where the city buildings were designed with “flushometers,” a commercial jargon for tankless units that connect directly to the main water source without mechanical pumping aids. Commercial tankless toilets were used because they were easy to install and required less maintenance. They also took up less space since they did not use a tank.
Due to the nature of the water source, tankless toilets can provide a compact solution for both male and female hygiene requirements. This raises the price, to include the special washing features a “bidet” or “washlet” integrates for female use. In recent years, a great design change has become fashionable, making these tankless hybrids the desire of every household.
Flushometers
You will find many tankless toilets in commercial buildings since they require a high-pressure water source to be effective, most commercial building and some residential units have access to high-pressure water sources (15-20psi) and this type of model is called a Flushometer.
When the water pressure is lower than the 15psi limit, then the building must integrate a pumping mechanism to increase the water pressure.
The flushing control mechanism is basically a water valve built into the unit and can be either a simple system that meters out the amount of water per flow or a complex electronic one that can adjust both flow pressure and amount of water per flush.
Cheap Chinese versus Expensive American
When we researched tankless toilet models, we came across Chinese replica’s that are offered at 20% of the real model. We strongly suggest you resist the urge to buy cheap. Cheap is too expensive! The Chinese models use poor grade ceramics, no modern finishes and the mechanisms are usually fake and in many cases, don’t work at all. If you fall for the cheap Chinese models, you will end up having to replace it immediately, or in the best case, within three months.
The American and European models use modern technologies, conform to regulations and international standards, and will flush from the day you install them. They will also retain their sheen, maintain their ceramic shine, and come with a guarantee.

Eco-Friendly
One interesting fact about tankless units is the control they have over water usage. While the flush rate can be similar between tankless to standard models, the control of how much water you want in a flush can be regulated in some of the latest models. Water conservation is a major issue in this industry and technology is advancing fast; tankless units use the best water conservation technologies since they are directly linked to the water main and can take advantage of the pressure as well as control the flow.
Floor or Wall Mount?
The decision to place a tankless unit is dependent on two factors, the weight factor you have and the design you want to reach. If you are a heavy person, you should consider a floor mounted unit. If you prefer an aesthetic design and want a clean and clear floor, then a wall mounted unit is better.
One interesting factor is floor cleaning; if you have the floor mounted unit, there is more chance of “grunge” accumulating around the base of the unit. That is why wall mounted units offer a cleaner aesthetic and easier floor cleaning option. Having stated this, cleaning the wall unit replaces cleaning the floor.
Pros & Cons
Pros:
- Tankless technology connects a toilet to a water main that reduces the possibility of malfunctioning tank flushing units.
- The direct water mains connection uses less water through electronically controlled mechanisms.
- Tankless models are easier to install.
- Most models include a washlet (bidet) utilizing the high-pressure water source
Cons:
- The washlet (bidet) hybrids are more expensive than basic toilet models
- When there is a water outage, there is no tank to back up for that extra flush
- If there is a power outage, technology-based features will not work
Tankless Toilet Installation Guide
Installing a tankless toilet is generally easier than a two-piece toilet. As with any toilet system, there are only two types of installation to consider; either floor-mount or wall-mount. Installation requires matching up the toilet to the water source and fixing the toilet to the floor or wall that will both secure the unit as well as make it accessible to all users.
Unlike floor mounted units, wall hung toilets require special care for weight considerations. You must remember that the toilet seat will be used by various weighted individuals, ranging from lightweights such as kids to people that suffer from obesity. When planning the attachment of a wall mounted toilet unit, you must consider the structural forces of the wall and the bolts holding the toilet as well as the manufacturer’s specifications (weight limits).
The stages of installing a toilet are quite simple; we consider that you are replacing an old unit with a new one. Consider that you do not need to install a water tank, you just need to position your tankless toilet unit over the drainage pipes and make sure you have access to a water supply. The basic steps are:
- Turn of the water supply.
- Remove the old unit.
- Clean the area it was fixed in.
- Ready the supply and waste plumbing
- Connect the supply and waste plumbing
- Mount the toilet, install the seat
- For electronic units, attach the seat to a power supply

Frequently Asked Questions About Tankless Toilets
Since most toilets models come with specific installation guides and user manuals, we limit out FAQ to general questions that are appropriate for all tankless toilets.
- How does a Tankless toilet work? Tankless toilets use a regulated flushing system that is directly connected to the water mains.
- Can I install a tankless toilet in a penthouse of a skyscraper? Yes, however, you will need to consider water pressure. Most modern high-rise buildings have pumps installed in the architecture.
- How sensitive are motion detectors that raise toilet seats? Very sensitive, the more advanced modes allow for sensitivity settings. If you don’t have a programmable setting, some seats will open and close every time you are around 10 feet from the unit. In some instances, dogs and cats can cause the more sensitive sensors to operate as well.
- I have low-pressure water, can I connect a tankless toilet? Yes, but you should consider checking to see if you will need a pump to increase the water pressure.
- My toilet has automatic flushing, what happens in a power outage? Any electronic device will cease to function in a power outage, including a tankless toilet. However, some models have a backup power source, a small battery that keeps the basic operations working for a short while.
- Do tankless toilets conserve water waste? Yes, tankless toilets provide control over the amount of water that flows through the system. The more technological ones provide full adjustable control.
- Is it easy to install a tankless unit? Yes, tankless toilets are single piece items that require a standard connection to a waste outlet and a water source connection that can connect to the main water pipe or in some cases to a sink.
- Why are some tankless models so expensive? As with any technology and fashion, tankless units can be very expensive when incorporating other technologies such as a “washlet,” remote control for seat heating, automatic flushing and set opening control.
- What are the main problems with a tankless toilet? This all depends on the level of technology you invest in. The more complicated a system, the more chances you have of issues arising. For instance, a regulated flush unit can be either mechanical or electronic. If the mechanism is electronic, then power sources and programming issues can arise. If the control is mechanical, then wear and tear issues can arise.

Bottom Line
We reviewed quite a number of models including the best tankless toilets in the market and found that they require less space, and can be in the most confined or awkward spaces. In some instances, they can be situated far from a water source. Due to their high-water pressure feature, they provide added comfort when using a hybrid. The downside is that prices can be extremely high, well over $1,000 a unit.
Very confused. What are the best flushometer toilets? I cant find any list of flushometer toilets and these appear to be not the same as tankless toilets.
For example Kohler sells flushometers but apparently not the toilets. Thanks!
