Typically, a clean, easy to operate and germ-free toilet is everyone’s wish. A touchless toilet affords you all this luxury. An automatic flush toilet comes with an inbuilt mechanism that allow you to flush it without necessarily making contact with the flush trip lever or button.

As Paul Horowitz, Medical Director at Legacy Health System says, the toilets flush lever is among a few other high-touch surfaces that might lead to spread of germs around the house. Therefore, an alternative to the traditional lever flushing mechanism is a huge welcome.

This guide has some of the best touchless toilets that we think might save you from the lengthy search.

1. Kohler K-6418-0 Cimarron – Editor’s Choice

AquiaPiston Flushing Technology

One of the best touchless units from this brand, the Kohler K-6418-0 comes in a wide range of colors to cater for different homeowners’ needs. The available options are: black, dune, ice gray, dune, sandbar, and white.

This toilet features Kohler’s Aquiapiston Flushing technology. Unlike the typical flapper that is mounted on a hinge to open partially when the button is pressed, the aquiapiston system lifts off the valve completely resulting to a 360-degree waterfall.

The manufacturer states that this is its most powerful gravity-fed flushing system that aims at eliminating plugging while offering a thoroughly cleaned and rinsed bowl.

4-AA Battery Operated No-Touch Sensor

This toilet uses a 4-AA battery operated no-touch sensor that has been mounted inside the cistern. Several reviewers report that the toilet sensor is quite strong. You only need to pass your hand once.

Other impressive features about this toilet include an elongated bowl and a comfort height. This combo makes an ideal option for special groups including tall people, senior citizens, and people with bad backs or arthritis.

WaterSense Certified

For those who care so much about the environment (I bet we all should), this toilet is WaterSense certified thanks to its 1.28 GPF flush rate. This low flush rate will also save you chunks of money on your water bills each year.

From the customer’s reviews, we have stumbled on some flaws regarding this commode. For instance, the batteries tend to run out quickly.

Secondly, some report that it flushes randomly after some period of use. Luckily, Kohler tends to have a fix for this problem and the latest models might have been redesigned.

2. Kohler K-8687-0 San Souci – Premium Pick

Easy To Maintain

The next model here integrates the tank and the bowl to offer you a seamless model that not only boosts your bathroom’s design but its hygiene levels too.

One piece toilets have several benefits over their 2 piece counterparts. First, they may be easy to maintain since they don’t have a crevice between the tank and the bowl that tends to form leaks in 2 piece models.

This crevice also makes cleaning the 2-piece units a little bit hard especially for germophobes. Lastly, there is a guarantee that your toilet will arrive on the same day, rather than have each part shipped on different dates.

Compact Elongated Bowl

The Kohler K-8687-0 features a compact elongated bowl. The benefit here is that you get a bowl that supports you better without protruding so much into your small bathroom.

To top up to its comfort levels, you also get a model with chair-height seating. This makes life easier for most adults when standing and sitting.

This toilet is quite similar to its sibling, the K-6418-0 regarding performance. It utilizes a 4-battery powered sensor that automatically triggers Aquapiston flushing mechanism. This sensor unit beeps to alert you when it’s time to replace the batteries.

1.28 GPF Flush Rate

The manufacturer states that the tank, bowl, and trapway have been precision-engineered to increase the effectiveness of each flush. Its WaterSense-certified flush system consumes 1.28 GPF and has a durable canister to curb leaks and to help keep your bills at manageable levels.

3. Kohler K-6419-0 Cimarron – Budget Buy

Ideal For Small Bathrooms

Last on our list is the Kohler k-6419-0 toilet. This model combines the K-4347 bowl and the K-5693 tank. Although its 2 piece makes it an underdog when compared to the K-8687-0, it makes up for that at other fronts including ease of replacement and installation.

6 Color Options

Whatever your bathroom’s design, it’s very likely that you’ll get a model with the right color to match it from the 6 options at your disposal: ice gray, almond, white, biscuit, sandbar, and dune.

Its round bowl suggests that it will fit quite well in most compact bathrooms and powder rooms. Its fully glazed exterior helps to maintain cleanliness and does not demand complicated cleaning procedures.

Just like its siblings above, this system features a touchless module that senses your hand to actuate a flush after usage.

Aquapiston Flushing Technology

This toilet brings together the Aquapiston flushing technology, the power of gravity, and a siphon action to offer successful flushes. Of noteworthy is that the system uses 1.28 gallons per flush and may, therefore, qualify you for the rebate program.

The issue of phantom flushes still makes an appearance on this toilet’s negative reviews. However, some homeowners report that the manufacturer fixed the problem and their fixtures work better now.

Which Is The Best Touchless Toilet?

Editor’s Choice

Overall, I wouldn’t say that there is an ace touchless flusher from the list above. Most of them tend to break after some time or result in phantom flushes.

However, assuming that Kohler has since rectified the major hitch plaguing these models, the Kohler K-6418-0 Cimarron would be our number one recommendation. This bad boy brings everything you might look for in a good toilet: a great design, elongated bowl, and comfort height.

Best Touchless Toilet Buying Guide

Brand

Touchless toilets are still new on the market and manufacturers have not yet perfected the sensor’s odds and ends. That being said, you want to go with a brand that will stand by its model in case of a failure. Think of Toto, Kohler, and American Standard here.

Water Efficiency

Of course, technology is meant to improve our lives. Consider a toilet that will save you water and money besides making life fun. Most of the models today use utmost 1.6 GPF (gallons per flush).

Some models also have sensors with dual flushing systems that use varying amount of water depending on the type of waste. Although you have to pay for this advantage, dual flush toilets go a long way in conserving the environment.

Bowl Shape

An elongated bowl is said to be more spacious and comfortable than a round bowl. If you are of this opinion and your bathroom is large enough, then this should be your go-to bowl shape.

On the other hand, round bowl toilets are known for their ability to fit in tight areas. If you want a commode for a super small powder room, then you may want to try out these.

Extremely compact bathrooms, however, may require a new approach such as a wall hung commode or a corner toilet.

Seat Height

A suitable height should be equivalent to a chair’s height. Roughly 17 to 19 inches, these will guarantee you comfort, since sitting and standing will be easy.

Don’t want to buy a new toilet? No Problem

Mind you, you don’t have to purchase a new toilet to enjoy the non-touch convenience. You could retrofit your standard toilet to a non-touch model simply by installing the automatic toilet flusher such as the Kohler K-1954-0. These are affordable sensor kits that install in utmost 20 minutes without any special tools.

Benefits Of Installing A Hands-Free Toilet Flusher

Conclusion

Touchless flushing toilets have not yet gained a foothold in most households. But they may be the way to go thanks to the advancement in toilet technology and the increased awareness on hygiene.

As you’ve just seen, you don’t actually need to buy the entire toilet system if you are skeptical about the way these models work. You could buy the sensor alone and change your current toilet to a no-touch in 20 minutes.
