The 10 Best Tankless Toilets – Sleek, Comfortable, Efficient

Last Updated on July 28, 2023 by toilethaven

What is the best tankless toilet to buy? Are tankless toilets worth the money? How does a tankless toilet work? What are the pros and cons of a tankless toilet? These are some of the questions would-be buyers of tankless toilets often ask themselves before buying one.

A tankless toilet is a flush toilet without a tank on top of the bowl but is supplied with water under high pressure sufficient to flush the toilet.

The reason toilets are sold with a toilet tank is that most homes’ water supply does not have enough pressure to flush a toilet. A toilet tank, therefore, provides a ready water supply which, with the help of gravity, is enough to clear the bowl.

Tankless toilets are both stylish and modern. The majority of them are what are commonly known as bidet toilet combos, meaning the toilet also acts as a bidet.

The 10 best Tankless Toilets are:

Toilet Flush Rate (GPF) Price Range
1. Toto Neorest 700H 0.8/1 High
2. Kohler Veil 0.8/1.28 High
3. Woodbridge B-0960S 1/1.6 Low
4. Saniflo Sanicompact 1/1.28 Low
5. Toto Neorest 550H 0.8/1 Mid-range
6. Bio Bidet IB 835 1.6 Mid-range
7. Dyconn Faucet Niara 1.18 Low
8. Kohler Karing 1.28 High
9. Toto G400 0.98/1.28 Mid-range
10. Ove Decors 1.28 Low

The following is a detailed review of the 10 best tankless toilets.

The Toto Neorest 700 H is probably the best tankless toilet anyone could ever buy. There is nothing in this toilet that will not leave you breathless. The surest thing about this toilet is that you will take longer in the bathroom than you would with another toilet.

Toto combined the 0.8/1 GPF dual-flush functionality with their revolutionary Ewater+ disinfection technology in the design of this toilet. This technology uses the natural properties of normal tap water to turn it into a harmless acidic solution that acts like normal bleach.

Apart from disinfecting the bowl and the bidet seat nozzle, this water also pre-mists the bowl before use so that waste does not stick. It, therefore, eliminates the need to use harsh chemicals while cleaning.

The culmination of comfort and luxury greets you the moment you enter the bathroom. If it is during the night, the blue LED nightlight seat illuminates the bowl, and you have the option of not switching the bright bathroom lights, especially if you are straight from bed.

And no, you don’t need to open or close the toilet lid. It will notice your presence and automatically open, ushering you to the heated toilet seat. Cold winters will always find you warm on the throne.

You are going to be spoilt for choice between the rear, front, soft, oscillating, and pulsating cleanse options that are all on offer. You can even go ahead and adjust the temperature and pressure of the water spray to suit your personal preference. Alternatively, you can choose between one of the user memory (user presets) to automatically give you your daily “dose.”

A stream of warm air will then be blown all over your rear to make sure you are completely dry. An air deodorizer that will leave the bathroom feeling fresh all day will afterward automatically kick in.

The hands-free experience extends to the automatic flushing capability. Toto’s Tornado flushing system does the job in one round utilizing minimal water.

Since this is a dual flush toilet, you can use only 0.8 gallons per flush or the 1-gallon option depending on the waste you need to flush. And you will never need to flush twice.

Due to its low water consumption, it complies with the requirements of significant bodies like EPA’s WaterSense and CalGreen. It can be sold everywhere in the United States, including California and Texas.

Its toilet seat is at a comfortable 17.25 inches, which makes it ADA-compliant. Sitting and standing from the Toto Neorest 700H is very easy.


  • Hands-free everything
  • Heated toilet seat
  • Nightlight
  • Comfort height
  • Dual flush
  • Bidet functions


  • It is expensive

You are wondering why I ranked the Toto Neorest 700H and not the Toto Neorest 750H. The difference between these 2 is the UV cleaning light present in the 750H but absent in the 700H.

The UV lights periodically clean the toilet, especially when it has not been used. The price difference is, however, too big, and that function is already taken care of by the Ewater+; for more on this, check out this post.

2. Kohler Veil – Best Kohler Tankless Toilet

The Kohler Veil is a sleek and beautiful toilet. As hard as it is to use beauty and toilet in the same sentence, this is exactly what the Veil is.

Its curvy body combines so nicely with a comfortable height, with the top of the seat being more than 17 inches from the floor. It is therefore very easy to sit and stand on this toilet for old and tall people.

For maximum comfort, the toilet bowl is elongated, thereby offering a bigger surface area for the user to sit on. Cold toilet seats will be a thing of the past with this toilet in your bathroom.

The heated toilet seat ensures your body is kept warm for the entire time you are using this toilet. And you don’t need to touch the seat lid to open or close it. You will only need to adjust the distance you are comfortable with, and it will automatically close or open as you approach or leave.

Once your business is done, 78 fine nozzles with air-infused water will gently cleanse you. Ladies will absolutely fall in love with its gentle feminine cleansing function.

The nozzle, with the help of its oscillating function, moves back and forth in quick succession to clean over a wider area. You will not be required to adjust your body to reach the nozzle.

As if that is not enough, a pulsating wash will cleanse and massage you, using alternating streams of strong and soft water streams. It also comes with a spiral cleanse that washes over a broad area.

Warm air will then be blown over to keep your body dry and relaxed. Your bathroom will also be ever-fresh due to an automatic release of a deodorant to deal with any lingering odors.

Hygiene-wise, this toilet is top-notch. Sterilized water disinfects the nozzle after every wash. An automatic UV light will also sanitize the nozzle after every 24 hours. If you are sharing this facility, you can be guaranteed top hygiene standards.

Depending on the load, you can choose to use the 0.8 gallons per flush half flush option or the full 1.28 gallons per flush option. You do this from the wireless remote control mounted on the sidewall.

The Kohler Veil is also a compact toilet. With a depth of only 26.125 inches, it is quite space-efficient, which makes it a great tankless toilet for a small bathroom.

The Saniflo 023 Sanicompact Self-Contained Tankless Toilet is a compact but very effective toilet. It is one of the best tankless toilets for people with a small bathroom.

The Sanicompact is not just a tankless toilet. It is also a rear outlet as well as an upflush/macerating toilet.

A rear outlet toilet which is also known as a back outlet or rear discharge toilet, is a toilet that discharges its waste from its back and through the bathroom wall as opposed to floor/bottom outlet toilets.

An upflush/macerating toilet is a toilet that grinds waste into a slurry before pumping it out. They are mostly installed in basements or bathrooms far from the sewer line.

Most toilets flushing systems hugely depend on gravity to push water from the tank to the bowl for the siphoning action. The Saniflo Sanicompact depends on an electrical-powered pump.

Most up-flush toilets have the pump separate from the toilet, but the Sanicompact is fully integrated, which makes it a great choice.

It can be installed 9 feet below the sewer and up to 120 feet away from a soil stack. If you have a tiny bathroom in your basement that needs a small but modern toilet, look no further.

It comes with a dual-flush functionality that gives you the option of either using 1.28 or 1 gallon per flush. While at it, it gives you the option of connecting a sink. The gray water from the sink will be channeled to the toilet system and pumped out as soon as it enters.

The Sanicompact is designed to also offer comfort to its users in more than one way. It has a soft close toilet seat to eliminate the irritating sound of slamming seats. The toilet bowl is also elongated to offer more surface area to sit.

Saniflo Sanicompact boasts an 18.25-inch comfort height from the ground to the top of the seat. People with limited mobility or generally tall people will find this toilet very helpful in that regard.

Its self-venting system means that this toilet does not need a vent pipe. However, you will need to vent other appliances in your house in line with your local authority codes.


  • Competitively priced
  • Ideal for tight spots
  • Comfort height


  • Not easy to install
  • Hands-free features lacking
  • The toilet seat is not heated

So what is the difference between the Toto Neorest 550H and Toto Neorest 700H? These 2 toilets are very similar, especially in their cleanse functions.

The main difference between Toto Neorest 550H and Toto Neorest 700H is the dimensions. Toto Neorest 550H is more compact than 700H. It also has a standard height, while the 700H has a comfort/universal height.

The Toto Neorest 550H comes with an Ewater+ disinfection system. After every flush, Toto’s Ewater+ mists the bowl with electrolyzed water. This is the regular water found in tap water. A wet bowl aids in the elimination of water 80% better than a dry bowl.

This new technology also helps avoid using harsh chemicals while cleaning the toilet. Common chemicals in tap water are transformed into hypochlorous acid. This has the same properties as household bleach but is kind on the surface of the toilet.

The Cefiontect glaze makes it very easy to clean and maintain the natural glow of the toilet. It also makes it impossible for molds to grow or thrive.

The Neorest 550 is a hands-free automatic toilet in so many ways. As you approach the toilet, the lid will automatically lift off, and as soon as you are finished, it will automatically close as you move away from the toilet.

The elongated toilet seat has adjustable temperature settings for maximum comfort. The oscillating and pulsating washer leave you thoroughly cleaned, followed by a warm air drying experience.

Its automatic flush mechanism will notice when you are done, so you will not need to use your hands. All those features can be adjusted and controlled by a wireless remote when buying this toilet.

Its skirted design ensures no nooks and crannies for dirt to hide. Cleaning this toilet is, therefore, quick and easy. This, combined with other attributes, ensures your hygiene is never compromised.

The standard height may, however, be a little of an issue for people with mobility problems, the old, and generally tall people. With the emergence of comfort height toilets, some people may be forced to buy the Neorest 700H or 750H.

  • Cheaper than Toto Neorest 700H

Toilet paper will be a thing of the past as far as this toilet is concerned. After getting thoroughly cleaned, warm air will dry you out completely.

The toilet seat of the Bio Bidet Tankless toilet is heated so that you don’t freeze on the toilet, especially during winter. Although it is not the tallest toilet, it still has a decent seat height. Heavy folks have also been thought of! The maximum weight capacity of this toilet is 330 pounds.

Unlike many smart and tankless toilets, the Bio Bidet IB835 is easy to install. You don’t need a plumber to help you install it. If you can get a Philips screwdriver, a drill with a 3/8 inch bit, and an adjustable wrench, you will be home and dry.

The kick button at the bottom of the toilet ensures a completely hands-free operation. You have to kick it, and the lid will open.

If you want to use the facility at 2 or on a cold winter morning, you will not need to worry about freezing on the toilet. An LED nightlight heated toilet seat will be there waiting for you. The 93, 98, and 104 degrees temperature settings are available for you to choose the most convenient level.

During flushing, water is released from two sides of the bowl at very high pressure resulting in a very turbulent and powerful flush. The Niara uses only 1.18 gallons per flush. 

It first releases 0.7 gallons to create a vortex to sort of scrub the bowl, then release the remaining 0.48 gallons out of a small jet at the bottom to rinse and clear anything that might have been left behind.

Tankless Toilet Buying Guide


Just like many things in life, all tankless toilets are not made equal. Some will perform better than others, while others will look better. Some will even last longer than others. Without a doubt, some will cost more than others.

So, what factors should you consider before buying a tankless toilet? Here are some of them:

1. Cost


Tankless toilets generally cost more than tank toilets, but even amongst themselves, some cost way more than others. Before settling down on one choice over the others, you must consider how much it costs and how much you are willing to spend.

You should also consider the cost of repairs and maintenance. Expensive toilets will also have expensive replacement parts.

2. Color


Let’s face it; most toilets are white. White works better, especially when hygiene is something you cannot overlook. While we don’t discourage people from venturing out of white, as far as tankless toilets are concerned, you will never go wrong with white.

Black toilets are becoming popular, but in this instance, I would stick with white.

3. Power Reliability

Tankless toilets depend on electricity to run all their functions. Without electricity, a tankless toilet is useless. If you live in an area prone to chronic power outages, you might not enjoy the tankless toilets experience that much.

4. Comfort


Comfort means a lot of things when talking about toilets and tankless toilets, to be specific. From heated toilet seats, elongated bowls and seats, comfort/chair seat height, nightlight, automatic flush auto lid opening, closing, etc. This is the primary reason why tankless toilets are expensive.

Although some are less comfortable than others, tankless toilets are generally comfortable, and you will be spoilt for choice as far as comfort is concerned.

5. Toilet Dimensions


Tankless toilets look great whether you have a big bathroom or a tiny bathroom. Having said that, if you have a small bathroom where every inch counts, please take your time to consider all the toilets and their dimensions.

And don’t just take the dimensions you see on e-commerce websites. Those are most likely shipping dimensions. Visit the manufacturer’s website and download the toilet’s specification sheet.

6. The Toilet Rough-in


The rough-in is the distance between the rear wall of a toilet and the center of the toilet’s drainpipe. The standard rough-in of toilets is 12 inches. Other rough-ins like 10 and 14 also exist. Measure your toilet rough in before buying your tankless toilet of choice.

Tankless toilets being modern toilets have a standard rough-in of 12 inches. If you have a 10 or 14-inch rough-in in your bathroom and need to install a tankless toilet, consider buying an offset toilet flange.

An offset toilet flange helps to convert either 14 0r 10-inch rough-in toilets to 12-inch standard rough-in toilets. Read more about offset closet flanges here.

7. Water efficiency


Some toilets use up to 3 or more gallons per flush. Others use a meager 0.8 gallons per flush. The difference in the amount of water saved over a period of time is huge.

Make an effort to buy a toilet that uses less water which will be good for your pocket and the environment.

8. Legal requirements

You may like a certain tankless toilet, but you might be unable to buy it in certain states due to legal requirements.

For instance, any toilets sold in California must not use more than 1.28 gallons per flush. Also, toilets to be installed in public areas must comply with the Americans with Disability Act (ADA), which a requirement of comfort seat height (17-19 inches).

Tankless Toilets Vs. Wall-Hung Toilets

Wall-hung, also known as wall-mounted toilets, as their name suggests, are toilets that are mounted on the wall of the bathroom. Some people tend to confuse tankless toilets with wall-hung toilets.

Unlike tankless toilets, wall-hung toilets like the Toto Aqua wall-hung toilet have tanks only that are either concealed in the wall and hence invisible.

The tank is supported by a frame known as a carrier, where the bowl is mounted using long bolts. A secondary wall is then erected to conceal the tank and carrier.

I have written a detailed article on everything to do with wall-mounted toilets. Read it here.

Tankless Toilets Vs. Tank Toilets

Tank toilets are either one-piece toilets or two-piece toilets. Two-piece toilet tanks are connected to the bowl using bolts. Old two-piece toilets had the tank so high up the wall to give the water more force as it entered the bowl.

The tank-in-tank toilets are connected to the house water supply so that there is always water to flush the toilet at all times. The water pressure in the lines is not enough to flush the toilet, and that’s why the tanks are critical.

It is good to remember that in order for flushing to happen, a large quantity of water has to be dumped inside the toilet bowl within a very short time. This is why tankless toilets use water under high pressure.

In a tank toilet, when you flush, the water leaves the tank into the bowl through a flush valve. Tankless toilets use a flushometer. A flushometer is a device that releases a metered amount of water each time into the toilet bowl.

They are mostly found in public restrooms, mostly in urinals. Modern tankless toilets for residential applications have automatic flushing systems.

The Pros and Cons of Tankless Toilets

So, what are the benefits of tankless toilets? Let us look at the advantages and disadvantages of tankless toilets.

The Pros

These are the reasons why you should consider installing a tankless toilet over a tank toilet:

1. Space Efficient

A tankless toilet can make an otherwise small bathroom look big. The absence of the tank makes sure they take up less space, and hence the bathroom does not look stuffy.

2. Sleek design

Tankless toilets are sleek and beautiful. Having it in your home leaves your guests in awe. Apart from that, they help to complement your overall bathroom décor.

3. Fast flushing

With a tank toilet, you have to wait for it to refill after every flush. A tankless toilet is ever ready to be used. And you hardly ever have to flush twice.

4. No Leaks

You will hardly hear an owner of a tankless toilet complaining of a leaking toilet. The scenario is different, though, for people with a tank toilet. If it is not the flapper, it’s the fill valve or the tank-to-bowl gasket.

5. Easy to Clean

The smooth surface coupled with no crevices means that washing these toilets is easy. They also stay clean for longer.

The Cons

What are the disadvantages of tankless toilets over tank toilets?

1. They are Expensive

Tankless toilets are way more expensive than tank toilets. The reason for this is due to all the extra components that come. Comfort and luxury in life generally cost money.

2. They are Noisy

Due to the forceful power of the pressurized water, tankless toilets can be noisier compared to tank toilets.



From simple urinals and public toilets to the modern toilets they have become, tankless toilets are, without a doubt, the toilets of the future. It might take longer to edge out tank toilets completely, but it will get there. Do your due diligence, buy yourself the best tankless toilet, and start living the modern way.
