review of best compact toilets

Main Features and Factors

Here’s a list of seven important factors when choosing a compact toilet for a small bathroom.

✓ Space and Size Dimensions

compact small bathroom dimensions sizingSince you want to buy a small toilet, you probably don’t have a lot of space to spare. Before buying, it’s essential to measure the space for your toilet properly, or you might end up with a too-big unit that you can’t return. The most important measurement is a rough-in size, which is the length between the center of the toilet and the wall.

Additionally, you should consider the shape of the bowl. Oval and round bowls take up different amounts of space.   If your room is shallow, it may be a good idea to mark the toilet dimensions on the floor using tape so that your knees don’t end up pressing against the wall while using the toilet.

Read More: How to measure toilet dimensions

✓ Water Consumption

Wasting water is bad for both the environment and your wallet. Look for an efficient toilet. Old toilets consume around four times more water than more modern models. New models might be expensive, but they make an excellent long-term investment. Federal law requires toilets to meet EPA standards for water-saving.

Take a look at our 1.28 vs 1.6 GPF guide.

✓ Flush Efficiency

Flush efficiency refers to how much water the toilet requires to clean the bowl after use.

There are two types of toilets when it comes to flushing efficiency. Some units have traps to prevent clogging while others have valves that allow for a powerful flush. Choose carefully based on the size and needs of your household.

✓ Ease of Cleaning

When choosing a small toilet, go for the models that are easy to clean. Your main indicators should be the material and design of the tank and bowl.

You may be interested in our toilet bowl cleaner reviews.

✓ Toilet Height

Toilet height is an important factor that affects both comfort and accessibility for both adults and children. Most modern toilets have a convenient height that is similar to sitting in a chair.

✓ Consider The Environment (and Your Wallet)

Buying a water-efficient toilet will affect the environment, as well as your wallet. The best option is Dual Flush, which allows you to use a light flush for liquid waste and a solid flush for solid waste. Also, it’s good to consider using greywater for flushing. Some toilets come with a nice, long rubber hose, which allows you to do just that.

✓ Toilet Design

Toilets are something that we use every single day so it’s important to consider the design. If you have a traditional bathroom, a two-piece unit will do the job. However, for modern bathrooms, a single-piece unit would be the perfect fit.

American Standard H2Option
  • Sleek and compact design
  • Water efficient choice
  • Strong dual flush
  • Installation is a breeze
  • Seat is not included

The H2Option toilet is not your regular compact facility. It is one of the most consistently highly rated on consumer review platforms and one of the best-selling models currently. 

With a quiet dual-flush system actuated by silver-plated buttons on the top of the tank, this toilet is more space-efficient than toilets with side-flush systems.

It is also available in the round and elongated form; the round front bowl is your guy if you need space over comfort – not that the round isn’t comfortable. 

Still don’t see why this toilet is our Editor’s pick? Let’s help you with that. 

Although the H2Option is a two-piece, it has a triangular body design that allows you to squeeze it into corners and maximize every inch of your bathroom. 

However, it uses the standard 12-inch rough, which we believe they could have done better with a smaller size or a UniFit adapter. Still, there are many other reasons you’d love this toilet. Check out this comprehensive review of the American Standard H2Option toilet here.

TOTO CST243EF#01 Entrada dimensions
  • Easy to install
  • Good value for the quality
  • Meets EPA WaterSense and California’s CEC standards
  • Requires additional items for installation

The TOTO Entrada is a toilet series specifically designed for small homes. Available in both the round- and elongated front, you can decide to tilt further to its comfort side or the space-saving side. 

The Entrada toilets also use the 12-inch rough-in, making them relatively easy to install and replace and even widely compatible since most bathrooms use the 12-inch rough-in. However, something compact would have been more suitable for small-sized bathrooms. 

Another interesting thing about this toilet is its 15 1/4-inch wide, fast-filling tank, which supplements its low water use and holding capacity. 

According to customers, the Entrada series is possibly the best affordable toilet on the TOTO brand and would have been totally perfect if its scouring power reached all corners.

Summary of Recent Reviews

This is a powerful toilet according to customers.  The flush is reliable and powerful, leaving a clean bowl after use.  Several buyers mentioned that they replaced an older model with this toilet and noticed the water savings.  “Have used this model for six years and am very satisfied.”

Swiss Madison SM-1T257 Sublime II dimensions
  • Stylish, minimalist design
  • Water-efficient
  • Quick-release toilet seat
  • Install is challenging

The Swiss Madison SM-1T257, otherwise called the Sublime II, is one of the finest, most sought-after pieces in the Swiss Madison toilet series. It is a compact, one-piece that uses a top-mounted button-flush system.

We’d always pick a powerful, quiet flush anytime, so we appreciate the gravity dual-flush of this system, which allows you to save the noise, save the cost, and help the environment.

At the time of this write-up, we did not find any complaints about its space-managing features. Check this comprehensive review of the Swiss Madison Sublime II for more features.

  • Water efficient
  • ADA compliant
  • Glaze finish
  • Very quiet
  • Can be hard to clean due to the many nooks, crevices, and corners
  • Replacement seat can be hard to find

We’ll start with this: Here is a one-piece toilet that allows you to choose between the 17.5-inches ADA-compliant height and the 15-inch natural seating height. 

Although it is no different from most toilets since it uses a 12-inch rough-in, it stands out from the rest by taking up just a little over 15-inches in width, making it suitable to squeeze into the little space between your wall and the bathtub. 

The American Standard Champion 4 has a very efficient yet quiet flush system that offers users a discrete, convenient toilet time. 

While we did not find any complaints about its space-managing features, we found several about its flush system.

Johnson Pumps compact unit

Johnson Pumps are one of the world’s leading manufacturers of toilets and pumps for marine use. Their Aqua Toilet is a non-electric toilet designed for convenient use at all times. 

This toilet saves space through its non-tank design and its variety of space-saving options, from aesthetic design to the standard elongated or round bowl options. 

Like the HocanFlo, the Aqua-T toilet has automatic backflow prevention for different onboard mounting positions and configurations: above or below the waterline.

This toilet also has a “whisper-quiet” flush which is actuated by a T-shaped hand pump at the side, an efficient feature but space-maximizing drawback. 

Again, like the HocanFlo, customers have complained about the pump being faulty with two pluses: the seat being very flimsy and the automatic backflow prevention not working as it should.[/su_expand]

  • Known, reliable brand
  • Strong flush
  • Water-efficient design
  • Available in several colors including black
  • The toilet finish is prone to water rings
  • Flush parts were reported to break after some time

The Kohler Santa Rosa is a one-piece toilet that offers the exceptional qualities of the Kohler toilets to smaller-sized bathrooms. With a modified elongated bowl, a beautiful design, and various other appealing features, it’s hard not to see why this toilet ranks as most reviewed. 

Although elongated bowl toilets are space-consuming, this one isn’t because of its all-round integrated system. Its elongated bowl has a round front instead of an oval one for more leg space, and as a one-piece toilet, its tank-bowl merge takes up even less space than a two-piece. 

But here is where it had a close call: the side-trip flush lever. It probably would have been kicked off the compact toilet society if not for its ergonomic design. The Santa Rosa also uses the standard 12-inch rough-in.

Yes, the toilet has some very compact features, but we can’t say it is that great with space efficiency. So, unless you see what we aren’t, you should read more about its features.

As you’d expect from our second-best compact toilet, the Galba toilet is one of the smallest toilets of all time. The size of this toilet will make you wonder, “exactly how small can a toilet be without compromising quality?” 

The answer? – Galba Small. Despite its pixie size, this toilet is a sturdy, one-piece, customer-centric toilet available in elongated form.

It also has a quiet dual-flush system operated by a chrome-flat button on the top of its slim-fitted tank and uses the standard 12-inch rough-in, which many customers have shared not-so-pleasant reviews about. 

The chrome lever button is also not all that, as there are also complaints about it oxidizing quickly and turning green. So, the team should probably also look into improving its quality and integrating a UniFit adapter like the TOTO Vespin II.

It’s never really the end of the road with the TOTO toilets. The TOTO Ultramax II toilet is another excellent compact toilet that can surprisingly make the most of the smallest bathrooms. 

We love that it does not compromise on quality either because, despite its relatively slim tank, it delivers a massive flush with its chrome trip lever. Check here for more information on its flush system. 

The TOTO Ultramax II is not your regularly-priced one-piece toilet; it costs a tad bit more than most. But for some customers, this might be a convenient sacrifice for a toilet that fits most bathroom configurations. As an elongated bowl measuring about 28.3 inches, this toilet might need more space than the round bowl types but is suitably classified as compact since it is relatively smaller than most.

HocanFlo 500W-MY_toilet
  • You can install it anywhere
  • Good for low-pressure areas
  • Low water consumption
  • Slightly expensive

The HocanFlo 500W-MY is probably not a brand or toilet you’ve ever heard of since macerating toilets are not all that common. These toilets are often very bulky due to their unique flush mechanism. However, the HocanFlo made it to the list. 

This toilet is most renowned for its high versatility. Due to its ability to pump effluents upwards and sideways, this toilet is suitable for the most unusual spaces, including areas below water levels – that includes your basement.

It also has a non-return valve design, an important add-on to supplement its unique flush system. But one feature that could easily pass as most surprising about this toilet is its quiet flush. 

Its flush system has a dual-automatic flush design activated manually through a control system at the top of the lid. 

But despite all its amazing features, this toilet is not very popular amongst its customers, with many complaining about its pump system not working as it should.  

It is also a two-piece, elongated bowl toilet -two of the most common non-space-saving toilet qualities.

Kohler San Souci toilet reviewedThe Kohler San Souci is a compact-sized toilet that is great for smaller bathroom spaces and offers seamless installation. This toilet is available in two-bowl designs: the round- and the elongated structure, which are both great, but for space management, the round type is best. 

This San Souci is also a one-piece toilet which makes it again space-efficient. Its shorter tank also takes up less space to make your bathroom feel larger. 

The San Souci uses the relatively silent gravity flush system, making it extra-perfect for small-sized homes. Also, thanks to the entire toilet being just about 24.25 inches tall, you can maximize your bathroom area with over-the-toilet storage facilities for your bathroom essentials.

Now for it’s not so exceptional qualities. First, because it uses the standard 12-inch rough-in, it is convenient for regular bathrooms but might not be so suitable for small-sized bathrooms.

HOROW toilet installedThe Horow HWMT-8733U is not your basic compact toilet. Although it is an elongated bowl, its seat height is about 16″, which is 2″ shorter than the standard elongated bowls, making it more suitable for small-spaced bathrooms.

The HWMT-8733U is also a one-piece, an added feather to its space-efficient hat, and uses the water-efficient, quiet siphon jet dual flush system. 

A top-mounted chrome button operates its flush system, and the toilet is barely a foot wide, two more features that make it a great toilet for small bathrooms. 

The Horow HWMT-8733U is available in 2 rough-in options: the standard 12-inch and the smaller 10-inch size that allows it to be set a bit further back than most toilets. 

While the Horow HWMT-8733U could be your perfect compact toilet, you might want to re-check its seat quality to make sure it fits your needs, as several customers have complained about it.

HOROW compact unit installedA quick look at the Horow HWMT-8733S, and you’d notice it is a clear upgrade from the 8733U. The 8733S is much smaller than the 8733U and has a modified seat to ensure its size does not cramp on comfort. 

The 8733S goes over and beyond with its U-shaped seat instead of the regular round or elongated front. Thus, this toilet promises the space managing quality of the round bowl and the comfort of the elongated bowl. 

It also has a top-mounted button flush instead of the side lever, which allows it cuts back on space in that aspect as well. With a quiet flush system, the Horow HWMT-8733S is designed to offer discrete, convenient usage, especially in small-sized homes.

However, many customers have claimed the U-shaped seat is not so comfortable, and the flush isn’t as powerful as hoped.

DeerValley compact toilet

Like the Galba Small toilet, the DeerValley DV-1F52813 is a small, EPA-certified, one-piece toilet that is small enough to fit smaller-sized bathrooms and small spaces but wide enough to accommodate larger persons and allow convenient seating. 

Besides its one-piece design, this toilet is great for small homes and bathrooms because its tank protrudes only 6 ¼ inches from the wall, providing more leg space, and its flush system is quiet. 

The DeerValley DV-1F52813 is one of the many toilets with a 12-inch rough-in, which means you might not get any special perks in this aspect but would probably not have to make any major adjustments during installation or have any trouble with maintenance.

The WZ5079 is usually about 22 ¾” long, but in some cases, you might get a 23 ⅛” long piece, an engineering flaw. But, we appreciate that WinZo doesn’t let its customers go in blindly. There is a clear warning on their spec sheet, “Dimensions may vary by up to ⅜ inch.”

Of the WinZo mini-series, the WZ5079 is the shortest and is even smaller than the best-selling mini-Carus toilet by ¼”. It is actuated by a top-mounted button which saves more space and has a quiet, dual-flush that saves you the reverberating noise of some flush systems and some cost off your water bill. 

Although its space-maximizing capabilities are what we are going for, the width of its seat is almost too small, and if you enjoy spending long minutes on the toilet, your legs might go to sleep sooner than you’d expect.

Compact Toilets For Small Bathrooms: Buying Guide

As you can see, there are a lot of compact toilets designed specifically for smaller bathrooms. However, in order to choose the ideal one for you, we’ve listed some top factors to take into consideration:

Dimensions

First off, you’ll want to start by figuring out how compact you need the toilet to be. Not all compact toilets have the same size. Although a lot of them have similar dimensions, you’ll want to measure your bathroom and find out exactly how much space you have. One way to measure the necessary space is by marking out the dimensions of the toilet you are planning to buy using tape on the floor.

However, keep in mind that you shouldn’t try to squeeze the toilet in. Instead, be sure to leave a little bit of free space around the toilet. Finally, don’t forget to measure the rough-in. Although the standard in most cases is 12 inches, make sure to confirm the right size for your bathroom so you don’t buy a toilet that won’t fit.

Are Compact Toilets Comfortable?

Another very important factor to consider when buying a compact toilet is comfort. Compact toilets can often lack comfort as they are smaller than traditional toilets. Therefore, if comfort is an important factor for you, there are a few details to consider. First, look for toilets that have a right height seat, which is usually a little taller. Secondly, any toilet that has a compact elongated bowl instead of a round bowl will also be more comfortable.

Which Rough-In Is Ideal For Smaller Bathrooms?

In order to understand which rough-in is ideal for a smaller bathroom, you need to know exactly what rough-in means. Most toilets will work on either 12 or 10-inch rough-in. Those numbers represent the distance between the wall and the center of the toilet. If you are looking to fit a toilet in a smaller bathroom, a 10-inch rough-in would be ideal. This way, you save up to 2 inches of space. Therefore, if you have a 12-inch rough-in, buying a compact toilet is a much better option than trying to fit a regular toilet in the bathroom.

What Is A Half Bathroom?

As the name suggests, a half bathroom is a bathroom that doesn’t contain all the bathroom fixtures. This type of bathroom contains only a sink and a toilet, but not a shower or bathtub. Half bathrooms are usually quite small and thus, they are ideal for compact toilets. They are also generally located on the main level of the house and are mostly used by guests.

Can A Toilet Be Positioned In The Corner?

A lot of people who are trying to save up some space in the bathroom are wondering whether it is possible to position a toilet in the corner. Yes, it is possible to fit a toilet in the corner and what’s more, some toilets are even designed with a more of a triangular shape that fits in the corner. However, that doesn’t mean that it will save up some space.

But, if you have a toilet positioned in the corner, you don’t have to worry about “knee space” between the toilet and the wall. Don’t forget that most codes require that you have at least 30 inches of free space between the toilet and any sanitary fixture. Not only that but you must also have at least 15 inches of free space between the toilet and the sidewall.

Benefits of a Compact Toilet

Some people avoid buying a small toilet, thinking that it may lack features. However, these toilets are an excellent choice, especially for small spaces. They are easy to keep clean. Plus, they come in standard height which is great for adults and kids, while still taking up less space.

Installation Tips

Installing a compact toilet is usually simple. However, installation varies between models so always follow the user manual. Although some units might be more difficult than others, in general, it’s an easy process.

• Make sure to cut off the water supply to the existing toilet and do a final measurement before beginning the installation.

• Note that there are differences between single-piece and two-piece models so some parts of the process will require checking the user manual.

• Once the toilet is installed, you can reattach the water line and turn it on but before using the toilet, flush it a few times. There could be some leaks, and it’s better to notice them before use.

• Consider hiring a professional. Improper installation can lead to unit damage over time. As a result, you may spend more cash on servicing.

• Most compact toilets can be installed the same way as standard units. If you’ve already installed a larger toilet, installing a compact version won’t be a problem.

Cleaning

Cleaning a compact toilet is as important as cleaning any type of toilet. However, some toilets have features that allow them to stay cleaner for longer. You should aim to clean it once a week. If you clean the unit frequently, you won’t have to remove potential build-up, making your life simpler overall.

One-Piece vs. Two-Piece Toilets

Most toilets, regardless of their size, are made in either 1-piece or 2-piece designs. Two-piece toilets are a bit more affordable but more difficult to keep clean due to crevices, bolts, and hooks in the design. Single-piece toilets are virtually seamless making them easy to clean but they are more expensive and are also heavier, which can be an issue when installing.

Frequently Asked Questions

What Is Considered Small for a Bathroom?

Typically, if a bathroom is somewhere between 30 and 40 square feet, it is considered small. However, the actual dimensions of a small bathroom will vary depending on the size of the apartment or the home itself. Ultimately, a bathroom that has just enough room for a sink, toilet, and maybe a shower and/or tub would be considered a small space where a compact toilet might make the most sense.

Where Should I Position the Toilet?

Every fixture, including the toilet, must have at least 21 inches of floor space in front of it. Aside from that, you’ll want to leave at least 30 inches of free space to use for the toilet itself. Basically, 15 inches from the center out on each side of the toilet must be clear. Finally, the swing of the bathroom door and any bathroom cabinet doors must not interfere with the person using the toilet. Overall, we recommend leaving a little extra space if possible to ensure the toilet is easily accessible and comfortable to use.

Final Verdict

Compact toilets are specifically designed for smaller bathrooms and thus, can sometimes be a bit more expensive. However, there are a number of toilets that offer a great quality-price ratio, such as the Horow HWMT-8733U and the Horow HWMT-8733 from our recommendations. Ultimately, keep in mind that there are a number of great options out there. Whichever you select, be sure to measure the space in your bathroom to ensure a great fit, and don’t forget to use our tips to pick the perfect compact toilet for your small space.
