✓ Space and Size Dimensions
Since you are looking to purchase a space saving toilet, you probably don’t have a lot of space to spare.
Before looking for a new toilet, it’s essential to measure your bathroom space properly. You want to measure the total bathroom space, rough-in size and the toilet location.
A very important measurement is the rough-in size, which is the distance between the center of the toilet drain hole and the wall. Remember, only shop for toilets that fit this measurement.
Additionally, you should consider the shape of the bowl. Elongated and round bowls take up different amounts of space. Round bowls will save more space than elongated bowls.
If your room is tiny, it may be a good idea to mark the toilet dimensions on the floor using tape to ensure the door opens without hitting the toilet and sitting will be comfortable.

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 for smaller bathrooms.
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.

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.

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.”

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 makes it a great compact toilet to fit your bathroom.
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.

This toilet performs well with its water-efficient, powerful flush that consistently cleans the bowl. The design is perfect for a modern bathroom, especially if you’re limited on space. Multiple buyers even ordered this again for their additional bathrooms.
4. Kohler Santa Rosa – Most Reviewed

- Flush Score:
- Water Consumption: 1.28

- – 2.12″
- – 17.25″
- 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.

According to reviewers, the Kohler name lives up to its reputation with this toilet. Several mentioned that installation is straightforward, but be sure to purchase the wax ring separately. The height is comfortable for users, as is the included toilet seat.

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.

- White
Our Final Take
Buyers are happy with this compact toilet! Several shared that this option saves water, and still has an efficient flush. Beyond the reliable functionality, customers love the modern design of this affordable option. One buyer shared that they had theirs for over two years and have yet to have a clog!
6. TOTO UltraMax II Toilet
- ✓ Compact Highlights
- Total Length: (wall to edge) – 29.35″
- Bowl Shape:
- Flush Score:
- Water Consumption: 1.28
- Flushing System:
- Flush Type: Single
- Style: One-Piece
- Dimensions:
- Toilet – 28.37″ x 16.5″ x 28.75″
- – 12″
- – 2.12″
- – 17.25″
- ADA certified
- Available in grey and black finish
- Chrome lever
- Uses minimal amount of water to flush
- Bottom drain is not symmetrical, potentially leading to clogs
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.
Color Options:
- Cotton (01)
- Bone (03)
- Colonial White (11)
- Sedona Beige (12)
- Ebony (51) (not available in CeFiONtect)

Our Final Take
This compact toilet is easy for buyers to install. Several shared that the flush is powerful, even with its water-saving design. Many reported no clogging issues over time. There was some mention of delivery issues but that’s not the fault of the toilet design!
7. HocanFlo 500W-MY Toilet
- Water Consumption: 1.6
- Pumping Distance: 328ft horizontally or 29.5 ft vertically
- Bowl Shape:
- Flush Type: Single
- Style: Two-Piece
- Dimensions:
- Toilet – 25.4″ X 14.8″ X 29.3″
- 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.
8. Kohler San Souci Toilet
- ✓ Compact Highlights
- Total Length: (wall to edge) – 28.87″
- Bowl Shape:
- Flush Score:
- Water Consumption: 1.28
- Flushing System:
- Flush Type: Single
- Style: One-Piece
- Dimensions:
- Toilet – 27.87″ x 16.37″ x 25.31″
- – 12″
- (2.12″), Seat Height – 17.25″
- Quiet Close and grip tight seat
- Comfortable experience with elongated seat
- Low water consumption
- Modern design
- Slightly complicated to install
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.

Our Final Take
A sign of a good product is when buyers purchase multiple, which is the case with this toilet. Reviewers came back and bought this again for their additional bathrooms. This has a modern design, adding to the decor of your bathroom, and of course, it’s functional. The flush is powerful with no reports of regular clogging.

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.

After reading the reviews, it is no surprise that this is one of the higher-rated toilets on our list. “Looks nice super easy install and operation.” The size is perfect for a smaller bathroom, but it still packs a powerful, reliable flush.

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.

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.

12. WinZo WZ5079 Toilet – Most Compact
- ✓ Compact Highlights
- Total Length: (wall to edge) – 23.8″
- Bowl Shape:
- Water Consumption: 0.8/1.6
- Flushing System:
- Flush Type:
- Style: One-Piece
- Dimensions:
- Toilet – 22.8″ x 14.5″ x 29.13″
- – 12″
- – 16″
- Easy to keep clean
- Extremely large trapway
- Dual flush system
- Not ADA-compliant
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.

Buying Guide – Compact Toilets for Small Bathrooms
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.
Installation
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.
• Cut off the water supply to the existing toilet and do a final measurement before beginning the installation.
• Note differences between single-piece and two-piece models, 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.
Frequently Asked Questions
The best compact toilet on the market is the American Standard H2Option. This toilet does not compromise comfort in any way, while still saving you space in the bathroom. The toilet’s dual flush mechanism, easy installation, and sleek look make it an all-around winner.
The smallest toilets tend to have a depth of around 23 inches.
Yes, compact toilets are a common product on the market. The best compact toilets on the market right now are: the American Standard H2Option, TOTO Entrada, Swiss Madison SM-1T257, American Standard Champion 4, Johnson Pumps Aqua, and Kohler Santa Rosa.
When selecting a small toilet, first look at toilet size to make sure its compatible with your space. Once narrowed down, look at flush efficiency and water consumption as well as toilet height and cleaning ease to ensure maximum comfort.
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.
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.
