What is a Tankless Toilet?

A toilet with no tank is one that receives its water supply directly from a water pipe that provides enough pressure to give it that special flushing power, unlike toilets that do have tanks, which usually don’t have that extra oomph of water pressure.

By eliminating the tank, this gives the opportunity to save up on plenty of water, cutting your water bills down considerably.

Next to tankless toilets there are a lot of other types of toilets. Dont worry. we got you covered

​How do Tankless Toilets work?

The easiest way to relate to and understand how a tankless toilet works is to refer to your sink or bathtub- do either of them have tanks? Nope. Do they need a means of getting water by certain pressure? Yup! And this is how tankless toilets work too. The only difference is, the toilets use a bit more pressure in order to successfully flush down your business, no matter what the volume or mass is!

In most situations, the pressure coming from the direct pipeline connected to the toilet is enough to flush down the waste. But in some situations, like if you’re living on the 20th floor of a building, the pressure may not be strong enough. In this case, most people just get a pump to give the water that extra boost to get through the pipe and do what it needs to do without any issues.

​Floor Mounted Vs. Wall Mounted

So what is the difference between the two, and is one better than the other?

The names themselves are self-explanatory: Floor mounted toilets at attached to the floor of your bathroom while wall mounted ones are attached to the wall, not touching the floor at all.

Wall mounted tankless toilets tend to give more space and are especially ideal for small spaces, because they take up less space, and give the bathroom a feel of being more spacious as it doesn’t touch the floor. They give a minimalist edge to the design of the bathroom[1]. They are especially useful because they give you the freedom to adjust the height of the toilet, which is actually very important, given the person or people who will be using it.

The only issue with wall mounted tankless toilets is that they can be quite costly to install.

Floor mounted tankless toilets are extremely affordable and much easier to repair in comparison the wall mount.

They do, however, take up more space and can prove to be more difficult to clean because of the hard to reach crevices. 

Our #1 Recommendation?

It’s safe to say that you have a hell of a lot of information down about the tankless toilet by now. All in all, they’re all good choices, you just have to see which one suits your space and taste the most, and of course what features would be more to your liking.

However, if we were to recommend one ourselves, then it’s really a no brainer. The most appealing and practical tankless toilet would have to be the Toto Neorest. The only drawback you may have with investing in the Toto is that it is quite heavy on the wallet. The good news about that is that it is actually worth every penny! The features are insanely amazing, and really give the toilet experience a whole new meaning of luxury.

Just because you’re going to use the bathroom, doesn’t mean you don’t have the right to pamper yourself to something that is aesthetically pleasing as well as technologically advanced enough to give you maximum comfort!
