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? This 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 instead supplied with water under high pressure sufficient to flush the toilet.

The reason toilets are sold with a toilet tank is because 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. 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 700K 0.8/1 High
2. Kohler Veil 0.8/1.28 High

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 which acts like normal bleach.

Apart from disinfecting the bowl and the bidet seat nozzle, this water 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 the of the water spray to suit personal preference. Alternatively, you can go ahead and 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 afterwards 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 either choose to 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 is compliant with the requirements of major bodies like EPA’s WaterSense and CalGreen. It can hence be sold everywhere in the United States including California and Texas.

It’s toilet seat is at a comfortable 17.25 inches which makes it ADA-compliant. Sitting and standing from the Toto Neorest 750H is therefore very easy.

Pros

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

Cons

  • It is expensive

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 cleans the toilet especially when it has not been in use for a while. The difference in price is however too big and that function is already taken care of by the Ewater+ .

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

Its curvaceous body combines up so nicely with a comfort height with the top of the seat being more than 17 inches from the floor. It is therefore very easy to sit and stand from 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 so as to to clean over a wider area. You will hence 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. You 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 therefore you are sharing this facility, you can be guaranteed of top hygiene standards.

You can choose to use the 0.8 gallons per flush half flush option or the full 1.28 gallons per flush option, depending on the load. 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 from a small bathroom.

Pros

  • Water efficient
  • Beautiful design
  • Comfort height
  • Compact size
  • self-sterilizing nozzle

Cons

  • Hard to self-install
  • Expensive

The Saniflo 023 Sanicompact Self-Contained Tankless Toilet is a compact but very effective toilet. It 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 upflush/macerating toilet.

A rear outlet toilet which is also know 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 system hugely depend on gravity to push water from the tank to the bowl for the siphoning action to take place. The Saniflo Sanicompact depends on a electrical-powered pump.

Most upflush toilets have the pump separate from the toilet but the Sanicompact is fully integated 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 a 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 seat. The toilet bowl is also elongated to offer more surface area to sit.

Saniflo Sanicompact boasts of 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. You will however be needed to vent other appliances in your house in line with your local authority codes.

Pros

  • Competitively priced
  • Ideal for tight spots
  • Comfort height

Cons

  • Not easy to install
  • Hands-free features lacking
  • Toilet seat not heated

So what is the difference between the Toto Neorest 550H and Toto Neorest 700H? These 2 toilets are actually 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 the 700H. It also has a standard height while the 700H has a comfort/universal height.

The Toto Neorest 550H comes with the Ewater+ disinfection system. After every flush, the 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 waster 80% better than a dry bowl.

This new technology also helps in the avoidance of using harsh chemicals while cleaning the toilet. Common chemicals in tap water are transformed into hypochlorous acid. This has the same properties as a household bleach but 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 leaves 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 that is included when you buy this toilet.

Its skirted design ensures there are 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 maybe forced to buy the Neorest 700H or 750H.

Pros

  • Ewater+ disinfection system
  • Cheaper than Toto Neorest 700H
  • Hands-free experience

Cons

  • Standard height toilet

For anyone looking to buy a toilet and a bidet but out of space for both fixtures this is their solution. It is an amazingly integrated product and people with small bathrooms will find it especially a much needed welcome to their lives.

When it comes to anything bidet you can trust Bio Bidet to deliver. Thy are the manufacturer of the Bio Bidet BB 2000 Bliss, probably the best bidet toilet seat in the market.

The Bio Bidet IB835 features a 2-in-1 nozzle which provides a posterior and a feminine cleanse functions use warm bubble-infused water. The nozzle washes over a wide area, thanks to the oscillating wash function so that you don’t need to move even an inch.

The wireless remote control gives you the liberty to adjust the water temperature and pressure among other functions easily. This touchscreen remote control is nicely illustrated making it very easy to use.

Toilet paper will be a thing of the past in 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 winters. 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 rather easy to install. You actually 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 customer care at Bio Bidet is great. If there is a detail that you are not sure of they are more than happy to listen and explain whatever that you need to know.

Pros

  • Wide cleaning

The Niara tankless toilet is a modern and fully automated toilet. It has integrated the functions of a toilet and a bidet into one amazing product.

By the press of a button, you get to choose the water pressure, nozzle position as well as the temperature of the water and the toilet seat. You are therefore assured of a spa-like treatment for the entire duration you are on the toilet.

The kick button at the bottom of the toilet ensures a completely hands-free operation. You just have to kick it and the lid will open. When you are done using the toilet you will again give it a kick to close the lid and flush. Don’t worry about the kicking. It’s a gentle kick using your leg. Not kicking to hurt it.

In the event you want to use the facility at 2 in the morning 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 into a very turbulent and powerful flush. The Niara uses only 1.18 gallons per flush.  It initially 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

Pros

  • Kick-button for lid opening/closing
  • Heated seat and nightlight
  • Powerful flushing
  • Water-efficient
  • Sleek

Cons

  • It is expensive
  • Not easy to install

For most people, going to the toilet poses several unpleasant/uncomfortable situations. Bending over to lift the toilet lid, turning to access toilet paper, putting the lid down among other movements are not only tedious for people with limited mobility, but are also unhygienic.

If you are a couple sharing this toilet, you can adjust and save settings for the heated seat, water temperature and air dryer so that you don’t have to do it all the time. A hand-held or wall mounted remote comes in handy if you have guests who will want to use their own settings for maximum comfort and relaxation

Review

This is another great product from Toto.  A dual flush tankless toilet integrated with a Toto washlet/bidet seat while utilizing the Tornado flushing technology.

If you do not have enough money to buy the Toto Neorest toilet models then this is a good alternative. It offers most of the features that are also offered by the Toto Neorest.

The main difference between the Toto G400 and Toto Neorest is that Toto Neorest toilets uses an instant water heating system while the Toto G400 depends on a hot water reservoir at the back of the seat.

You are therefore always guaranteed endless supply of hot water with the Toto Neorest but the hot water in the Toto G400 is limited

Its surface is coated with the Toto’s C glaze which combines really well with the premist function of this toilet. This combination leaves the toilet bowl with a most surface and therefore inhibiting waste from adhering on it.

For your added comfort, the lid will automatically open and close every time you use this toilet. After doing your usual on the toilet, a self-cleansing wand will appear to thoroughly wash your nether region.

You will be spoilt for choice as you choose the best cleanse function that suits your body. From a front cleanse, soft rear cleanse, rear cleanse, oscillating and pulsating cleanse, you are guaranteed to leave the bathroom feeling absolutely relaxed.

The Toto G00’s bidet seat is elongated and heated for extra comfort especially on cold days and nights. And that is not all. The toilet seat is at a comfort height hence sitting and standing is really easy.

Pros

  • Automatic opening/closing of the toilet lid
  • Washlet works amazingly well
  • Comfort height

Cons

  • The dryer is not as powerful as would be needed
  • Limited hot water

Ove Decors is not as big brand as the others but it will do some serious justice to your bathroom. It has smart bidet toilet seat incorporated with a powerful flush unit scoring a MaP score of 800g.

The one thing that most people complain about in this toilet is the installations instructions not being clear. You get a feeling they were written by someone who is not a native English speaker.

Cons

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 than others. 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 really 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 where 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 really 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 leave 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 thing 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 and 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 in as far us comfort is concerned.

5. Toilet Dimensions

Tankless toilets looks 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 ecommerce 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 meagre 0.8 gallons per flush. The difference in the amount of water saved over a period of time is is huge.

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

8. Legal requirements

You may like a certain tankless toilets 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 each flush. Also, toilets to be installed in public areas must comply with the Americans with Disability act (ADA) which have 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 which 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 actually have tanks only that they are either concealed in the wall and hence invisible.

The tank is supported by a frame known as carrier, where also 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 toilets 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.
