Eco-friendly Features

A water conservation toilet is an important aspect to consider when buying tankless toilets. While most of them use water sparingly, there are models that you can regulate and choose the amount of water you prefer to use.

They are not only eco-friendly but also save you money in the long run in the form of monthly water bills. Eco-friendly tankless toilets also curb the wastage of water due to the amounts used when flushed.

Wall or Floor Mounted Unit?

The decision for either a wall or floor mounted toilet varies in different individuals. A floor-mounted toilet is ideal for a bathroom with high traffic as it provides stability and can cater to a larger amount of people ranging from the elderly, physically challenged, potty-training kids and overweight individuals.

On the other hand, wall-mounted toilets allow you to have an aesthetic feel to your bathroom and an easier time cleaning your floor.

Manual Operation Options

If you live in an area that suffers from bouts of erratic power supply, ensure to purchase a tankless toilet that offers manual options, especially a flush button. This will save you from bathroom disasters that may occur if the power supply is interrupted.

Flushing System

A quality tankless toilet gets rid of waste in one flash. This features a powerful and efficient flushing system. It also means that you will use less water to keep your toilet clean. Always go for a toilet that uses the cyclone system preferably equipped with a siphon jet.


Sitting comfort should also be a top priority. The elongated bowl design offers more space and supports the right posture. You can also check out heat regulated bowls as an extra comfort feature and bowl lights that can illuminate the bowl even in the dark.

Beware of Replica

This is one of the most important factors to be on the lookout for when buying tankless toilets. Due to their popularity, there are a lot of replicas mainly from China. They are cheap, which is what attracts potential buyers, but they are made of sub-standard material which makes their quality poor.

As the saying goes, cheap is expensive and you will find that you will have to replace these cheap replicas frequently. Assure that you buy from a trusted seller, and a tried and tested brand. A reliable brand will have sufficient information on the product and an excellent after-sales support system.



1. How do tankless toilets operate without tanks?

Instead of a tank, the toilet receives its supply of water directly from a high-pressure pipe. The pressure is usually sufficient to flush waste in one swoop.

2. Can tankless toilets work with low water pressure?

As stated above, tankless toilets require high-pressure water flow to function well. If you experience low water pressure, you can still install a tankless toilet, but you will need to consult a professional plumber on ways to boost the existing low water pressure.

3. Are tankless toilets costly?

Like every product on the market, there is a tankless toilet to match every budget.

4. Do tankless toilets conserve water?

Compared to conventional toilets, yes, they do. An average tankless toilet flush dispenses 0.8-1.6 gallons per flush, while other toilets can use up 3 gallons per flush.


Tankless toilets are the future as they are now in tandem with technology, which is a major driving force for products today. In addition, they are less bulky hence do not take up a lot of space, they conserve water and are more hygienic than the tanked toilets. Some models are self-cleaning and require little to no maintenance.

The reviewed models offer excellent performance, are durable and come from reliable manufacturers. The units consist of the best tankless toilets, and chances are, you will find a suitable toilet to cater for your needs in the above list.
