Best Tankless Toilets

The best tankless toilet saves not only your space but your money, and sometimes mental health. It does not contain a flushing tank or cistern behind it. All you see is a bowl when you look at it. Sometimes the bowl is shaped differently, and you simply don’t notice the tank that comes attached to the toilet.

These toilets are usually not tankless at all. They just have the tank somewhere inside the model or attached separately. The bowl itself won’t flush. This is why you need to learn the subject before buying anything. Follow my recommendations on the most popular options.

Tankless Toilets Guide

WOODBRIDGE B-0960S Toilet

People who search for tankless toilets usually want to save space in the bathroom. However, there is a wide range of models that answer this demand and offer even more. So, how to pick only one of them?

How to choose the best tankless toilet?

You have already learned how do tankless toilets work; now you have to focus on the features it offers. There are several of the most important things to consider:

  • Measurements. You can’t squeeze the toilet bigger than the empty space you have. Pay attention to the length and height of the product. The widespread lengths of the bowl are 16-18 inches. The most popular shape is either elongated or round. The market always offers bigger or smaller options. Comfort height is 16-17 inches.
  • Level of disturbance. If you don’t want to get disturbed by loud noises of water flushing in the toilet, you have to find the noiseless model. Besides, some models have a slow closing lid. Forget about loud slamming or flushing.
  • Position. One of the most popular types of tankless toilets has the tank hidden behind the wall. The other one contains the cistern at the back of the bowl. Both of them can be either floor or wall mounted. Pick the one that is the most beneficial for your bathroom.
  • Power of flush. Almost all the models on the list are water-saving. High-efficiency toilets use 0.8 gpf at the minimum and 1.6 gpf at the average mode.

How to install a tankless toilet?

Depending on the model you pick, you need to take measures, pick the right instruments, and even call a professional if you are not sure about your skills. I recommend calling a professional if you have never done it before.

Most of the toilets on the list are sold with all the bolts and screws. You still have to attach the bowl to the pipe. Besides, if the toilet requires electricity, you need to install it somewhere near the electric outage.

FAQ on Tankless Toilets

Toilet WOODBRIDGE B-0960S B0960S

If you still have questions about these toilets, you may find your answers here. I have gathered the most popular questions for you. Hopingly, my answers will help you.

How does a tankless toilet work?

This toilet works almost the same as the classic one. It is united with the water pipe, and it flushes the wastes whenever you press the button or turn on automatic flushing. The main difference is that the tank is hidden either behind the wall or behind the bowl.

It is more compact and consumes less water than the classic model. The flushing system can be joined directly to the line of the water supply. Learn everything about it, even how to fix the toilet.

Can I put a tankless toilet in my home?

You can put a tankless toilet even on the highest floor of a skyscraper. Take into consideration the space you can provide, the water pressure that can be supplied, and the electric outage location. You can install the modern flush toilet without a tank either by yourself or with the help of an experienced plumber.

How much space do tankless toilets save?

It depends on the model. The most compact can save up to 14-16 inches of space compared to the classic one with tanks. Wall-mounted bowls can save 9-12 inches of space compared to the floor-mounted options.
