Tankless toilets are so popular today because of their compact, fashionable, and high-tech design. As the name implies, tankless toilets come without a tank. Unlike regular ones that have water in the tanks, no-tank toilets connect directly to the water supply pipes. They use small electric pumps to draw water from the pipes into the bowl.
Their most significant advantage is that they create more space in the bathroom to accommodate other fixtures like tables, shelves, and cabinets. Since they have no tanks, you can install them at any location in the house provided there is a suitable plumbing connection.

Tankless Toilets - A Comprehensive Buying Guide
You should not pay for any product without taking the time to check its build-quality. This is because the quality will affect the durability and performance of the toilet. So, we recommend you find a model with the best quality though it might come at a price.
2. Power Supply
If you do not have regular power supply in your home, you should avoid buying an electrically operated tankless toilet. However, some models use a battery and can flush when there is a power outage manually.
Tankless toilets are either floor-mounted or wall-mounted. You should consider the toilet’s design and your wall’s ability to support its weight before choosing any of these types.
- Floor-mounted – If you have adequate bathroom space, you can select a floor mount model. It is fixed to the floor, making it easier to install than the wall hung types. However, once it is installed, you cannot easily adjust its height.
- Wall-mounted –These toilets hang on the walls of the bathroom. They are ideal for homes with limited space. Notably, they have a sleek design and are easy to clean.
The fact that these toilets are without tanks means you can install them in tight places. However, they also come in different sizes and shapes, so take your time to compare them, then pick a model that will fit in your bathroom’s space.
5. Flushing Mechanism
You should be mindful that the toilet’s flushing system is powerful enough to clear the solid waste in a single flush. Some models might look appealing but will take around three to four times of flush; as a rule of thumb, avoid them. Of course, everyone wants a unit that works even as it looks good.
6. Water Consumption
If you want to save money on energy bills, then it is crucial to select a unit with high water savings. Be sure to get a model that conserves water but also has enough pressure to remove the waste quickly.
7. Seat Height
Different tankless toilets have heights ranging from 15 to 20 inches. If you are sharing the bathroom with others, especially with people with mobility issues, you should consider buying the comfort height types.
8. Bowl Shape
Tankless toilet shapes are categorized into three, namely, round, elongated, and compact elongated types.
- Round shape – No-tank toilets with round shapes have a bowl’s measurement of up to 28 to 31 inches. They are known to save more space but not quite comfortable to use.
- Elongated shape – These are suitable for people of all ages and offers the highest comfort. The bowl is between 28 to 31-5/8 inches, measured from the nose to the back.

Most no-tank toilets are more accessible to clean than others, depending on their shape, design, and finish. Besides, Sanagloss finish prevents the sticking of dirt on the bowl’s surface, reducing the rate of cleaning and restricts the use of harsh chemicals.
11. Advanced features
