best tankless toilets

If you’re thinking of investing in one of the toilets mentioned above, we believe that the benefits we are about to outline will convince you.

  • Compact Size

To start with, tankless toilets are much smaller than standard toilets. So, if you have a small bathroom, getting a tankless toilet is the way to go. Plus, thanks to this, you can install the toilet almost anywhere.

  • Water Conservation

Moving on, another characteristic of tankless toilets is that these toilets use less water in comparison with other models on the market. Why is that?

This is because many products have the dual flush feature, utilizing the right amount of water time after time; thus, they reduce waste. Plus, since the water enters the bowl at high pressure, less water is necessary for an effective cleanse. In fact, you can save up to 40,000 liters of water by replacing your current toilet with a dual flush toilet.

  • Modern Style

If you’re into minimalism, choosing a tankless toilet will definitely be down your alley. Most manufacturers create units that look impeccable and modern, meaning that such a product will definitely improve the aesthetics of your bathroom.

  • User-Friendly

What is more, another great thing about tankless toilets is that they are user-friendly, in the sense that they come with a wide range of advanced features. Additionally, cleaning them is really easy and time-efficient, thanks to the minimalist design.

What about Tankless Toilet Problems?

Since tankless toilets work differently, you should note that the installation process differs, as well. So, while there are many advantages that come with the territory, a disadvantage worth noting is that the installation process could be cumbersome. Plus, keep in mind that most models are electrically powered. So, if there’s no power, this means that the toilet won’t flush.

The main thing you expect of a high-quality toilet is to facilitate unmatched flushing performance. And this is the case for most tankless toilets. The top products, at the very least. For example, many of the models we presented to you are equipped with a dual flushing system.

Additionally, other toilets incorporate a flushing control mechanism. This is, usually, a water valve that regulates the amount of water per flow.

  • Floor vs. Wall Mount

Tankless toilets can either be wall-mounted or floor mounted. When choosing between these two types of products, you should consider the weight and the design of the toilet.

Additionally, it is highly recommended to restrict your use of chemical cleaners in this case. On a different note, make sure you factor in the shape of the bowl for use of cleaning, as well.

  • Does It Come with a Washlet?

Some tankless toilets are equipped with washlets, which aim at reducing the utilization of toilet paper. At the same time, in terms of efficiency, using water is much more efficient when it comes to removing waste, in comparison with toilet paper. Plus, if the toilet you choose features a washlet, you can regulate the temperature and pressure of the water, for a fully customized experience.

On a different note, the water jet can be significantly more soothing to people coping with hemorrhoids, rashes, or other skin conditions that can be worsened due to excess wiping.
