Horow T0338W Elongated One-Piece Toilet
Horow T0338W One-Piece Toilet
It’s a nice looking toilet with decent specs. If you prefer a chair-height toilet, this Horow T0338W has a seat height of 17.3″. The flushing mechanism is the standard canister type with a dual-flush function. This beauty has a flushing capacity of 1.28 GPF/0.8 GPF, and the bowl is the conventional rim type.
Cleaning should be easy with all the smooth surfaces on the exterior. But Installation may pose some challenges without strong arms and back as it is a 99 pounds one-piece toilet. The rough-in is the standard 12-inch, making it a typical installation with standard tools and accessories.
The toilet is rated MaP 1000. But according to Horow’s description on Amazon, the flush is 100% factory tested. So, that simply means you won’t find this Horow T0338W toilet in the official MaP list of Maximum Performance lab.
It’s a decent-performing toilet if you don’t mind a rimmed bowl and the self-proclaimed MaP rating, which means nothing so long as it works.
Can a smart bidet be fitted on this Horow T0338W toilet?
At the time of creating this post, there is no information indicating whether this Horow T0338W toilet meets the minimum clearance requirement between the tank and seat bolts. While some images may suggest a reasonable spacing, it is essential not to make assumptions.
If you plan to install a bidet seat, it is advisable to contact Horow directly to confirm the actual gap clearance. It is crucial to compare this information with the requirements of the specific brands and models of bidet seats you prefer. Otherwise, you may risk an improper installation and may cause irreparable damage to the bidet seat.
Alternatively, you can get this HOROW bidet toilet Seat for a snug fit if you don’t have any preferences.
Conclusion: It is just a regular elongated toilet with pretty standard features. Nothing much to shout about apart from its elegant appearance and economical pricing. And hearsay the after-sales support is commendable, which is the most important and subjective.

Winzo WZ5081 Elongated One-Piece Toilet
Winzo WZ5081 One-Piece Toilet
This Winzo WZ5081 is the shortest height toilet here, 23 inches from the floor to the tank lid. The seat height is slightly short of the ADA minimum of 17 inches at 16-1/2 inches. But that’s a slim seat to give it a contemporary look.
This shorty uses the traditional flapper valve, which pales in comparison to the canister type. But at 3 inches wide, the speed and volume are high enough to get you a strong flush. Though it is not as durable as the canister valve, getting 3rd party replacement is easy and costs almost nothing. And with a rimless bowl, the rinse should clear off the sticky bits easily.
Your cleaning regime with this low-profile toilet is more relaxing with all the flat exterior surfaces, and the open rim helps prevent any accumulation of dirt and debris.
Installation is just as challenging as the Horow T0338W with a weight of 103 Ibs. So watch your back if you are doing the installation alone. An assistant will be super helpful in cueing the flange bolt position when lowering the toilet onto the floor flange.
Bidet Seat Compatibility
It’s safe to say this Winzo WZ5081 is designed to be compatible with a wide range of bidet seats. There is enough clearance between the tank and the seat bolt holes. And the elongated bowl shape matches that of a typical bidet seat. You will have the widest option for bidet seats with this Winzo model. All the popular brands, like TOTO, Brondell, Bio Bidet, etc., should be able to fit on.
Trip Lever Advantage Over Push Button Flushing
A trip lever is not an option when the toilet is installed under a countertop, shelving rack, or cabinet with a very narrow space in between. A lot of folks overlooked this issue as they placed their focus solely on the toilet height. So, be mindful of this little issue if the fixture is tightly underneath a cabinet, countertop, or whatever. You will save yourself a ton of trouble and frustration.
This Winzo low-profile potty has a dual flush model with pushbutton flushing – WZ5081T. However, the dual flush model’s capacity is 1.5/0.9 GPF.
Conclusion: This Winzo WZ5081 offers many desirable features for a low-profile toilet. Its contemporary design, efficient flushing performance, easy-to-clean surfaces, and bidet seat compatibility are compelling options for those seeking a compact and functional toilet.
The only notable drawback is the durability of the flapper valve, but its easy replacement and affordable cost mitigate this concern. Plus, its low retail pricing makes it a hard-to-resist option.

DeerValley DV-1F52636 Prism One-Piece Toilet
DeerValley DV-1F52636 Prism One-Piece Toilet
The DeerValley DV-1F52636 is a pragmatic choice that combines a sleek minimalist exterior with a range of signature features of a modern toilet. If you need a touch of contemporary style but don’t have a generous budget to splurge on a KOHLER or TOTO, this will be the perfect toilet you may consider.
At 26-7/16 inches, this beauty is the tallest among the other low-tank commodes featured here. However, this is not necessarily a disadvantage because the discussion here concerns low-profile toilets. In fact, a taller toilet will pull a stronger flush compared to the shorter models.
From the official spec sheet, the seat height is indicated as 16-3/8 inches, so it is not an ADA-compliant height or comfort height. But it can easily be attained by changing to a thicker seat. It’s just half an inch shy of ADA’s minimum of 17 inches, so does it really make a difference in seating comfort?
The toilet utilizes a tornado-style flush, which is desirable as the swirling action cleans much better than the traditional rain-down rinse. And for that, it only means it has a rimless bowl which is a better design that is easy to upkeep. And with a 1.28 GPF flushing capacity, you won’t have to worry about shipping to California or other States with strict regulations on water consumption.
It’s a pushbutton-activated dual-flush toilet with a 1.28/0.8 GPF flushing capacity.
Can a Bidet Seat be Installed on This Toilet?
Yes. Probably any brand of bidet seat can be installed on this DeerValley Prism toilet.
There is a 2-1/4″ clearance between the tank and seat bolts, which is slightly more than the minimum of 2″ required by most bidet seat brands. And more importantly, there isn’t a curve that connects the bowl and tank, so that eliminates all concerns of not getting the bidet to sit flat and firmly on the bowl.
Conclusion: This DeerValley DV-1F52636 Prism offers great value for money, encompassing all the modern features of today’s toilet design. Its low tank minimalist skirted design, water-efficient dual flush system, tornado flushing, and rimless bowl make it a pragmatic choice for those seeking a reliable and functional toilet without compromising style.
The only concern is it’s nearly 27 inches in height which might not be suitable for some installations under a countertop or storage cabinet. So make sure to carefully measure the space intended for this tall shorty, and don’t forget to consider the pushbutton on the tank cover. It’s important to leave a big enough space between the tank cover and what’s above for maintenance purposes.

American Standard Colony Elongated One-Piece Toilet
American Standard Colony One-Piece Toilet
Some folks may have reservations about its appearance, but it packs a powerful flush with a MaP 800 rating which renders it an irresistible choice. This American Standard Colony toilet is a workhorse if you want a fuss-free bathroom fixture.
And standing at 26-3/16 inches, this American Standard Colony toilet is designed to fit seamlessly under most countertops or storage racks, making it the perfect solution for spaces with limited vertical clearance.
Add to its low height advantage, the side trip lever is the correct flushing mechanism to make it fully functional, even when there is very little room above the lid.
Notably, the American Standard toilet is a right-height ADA-compliant model. With a seat height of 18-13/16 inches, it meets the accessibility standards outlined by the Americans with Disabilities Act. This makes it ideal for tall individuals, seniors, and persons with disabilities, providing easy access and enhanced comfort.
However, some users may find the toilet less desirable with a few uninspiring features. One of them is the exposed trapway, which may not appeal to those seeking a more streamlined and seamless look. The exposed trapway can make cleaning more challenging, as debris and dirt can accumulate in the crevices.
Another aspect to consider is the rimmed bowl design. The rimmed bowl features an inner rim along the top edge, which can accumulate dirt and limescale within the rim. It can pose some challenges in maintaining optimal cleanliness, especially when the water has high mineral content.
And these days, durability is a rare quality. It would have been better if the flush valve was the tower type instead of the dated, less durable chain and flapper.
What About Bidet Seat Compatibility?
As with most bidet seat brands, other than the seat dimensions and bowl shape requirement, the most critical is the clearance space between the tank and seat post holes. This Colony doesn’t seem to meet the minimum clearance required.
Fortunately, American Standard offers a range of bidet seats if you intend to swap the regular seat for a bidet seat. However, only two bidet models are compatible with this Colony 2961A104SC toilet – AquaWash 1.0 & AquaWash 2.0. Both are manually operated but go for the AquaWash 2.0 model if you need a heated seat and warm water.
Probably some KOHLER bidet seats might be able to fit in. You will need to look carefully into the shapes and dimensions of the bidet seat you prefer. Or call the bidet seat makers; they are all more than willing to help a potential customer.
Conclusion: Ultimately, personal preferences, budget considerations, and specific bathroom requirements will determine whether this American Standard Colony toilet is the right choice for your needs. But you will likely go for its powerful flush when you understand why low-profile toilets are not power flushers.
It’s a no-frills toilet, and its shortcomings are more like traditional features rather than treating them as disadvantages. Most folks will have no problem with these “drawbacks.” And in all honesty, it’s quite a looker too.

KOHLER San Souci One-Piece Toilet
The Kohler San Souci toilet is a chic and incredibly effective toilet created to improve your bathroom’s functionality and aesthetic appeal. It has some noteworthy qualities that make it a well-liked option among homeowners.
Furnished with KOHLER’s proprietary AquaPiston flushing system, the flush is strong and effective, which promises a clean flush every time. The 360 degrees canister flush valve allows more water to enter the bowl at any given time, creating a powerful swirling action that thoroughly cleans and clears waste from the bowl.
Besides, the AquaPiston valve requires a lower actuation force than usual. The elderly and people with health conditions or impairments can use the flush without struggle.
It’s a single-flush toilet with a flushing capacity of 1.28 gallons per flush (GPF), making it water-efficient and compliant with water-saving standards such as EPA’s WaterSense. And it comes in 2 versions – standard seat height and comfort height.
However, the standard seat height is a round bowl toilet, whereas the comfort height model has an elongated bowl. Both toilets have a height difference of about an inch (see Specifications below).
Bidet Seat Compatibility
There are French curves on the sides, joining the tank and bowl. So, it may not be suitable for some bidet seat brands or models with broad backs and straight sides. (See image below)
If you want a bidet seat with this San Souci toilet without the hassle of ensuring compatibility, check out this KOHLER Bidet Seat Comparison Chart. But if you prefer a particular brand and model, please consult the bidet seat manufacturer or vendor.
Conclusion: The San Souci toilet boasts an elegant and contemporary design, adding sophistication to any bathroom décor. It features sleek curves, clean lines, and a compact profile, making it visually appealing and suitable for modern and traditional bathroom styles.
The only mismatch is the rimmed bowl that is so 80’ish. Hopefully, future models can adopt the rimless feature to better match the modern minimalist exterior. Performance-wise, you will not be disappointed with the AquaPiston flushing power and efficiency.
The toilets are available in six finishes – White, Biscuit, Dune, Ice Grey, Thunder Grey, and Black Black.

TOTO Carolina II One-Piece Elongated Toilet
TOTO Carolina II One-Piece Toilet
The exterior? Probably not so much if you compare it with the San Soucis. But if you are more for functionality and performance, don’t let this Carolina slip by. This toilet is meticulously crafted with advanced features that elevate both performance and convenience. It will be a notable addition to any bathroom, combining exceptional functionality with, well…, acceptable elegance.
The flushing power of this TOTO Carolina toilet excels with its Tornado Flushing System. It utilizes two powerful nozzles positioned strategically within the bowl to create a cyclonic rinsing action. The centrifugal force generated by the Tornado Flushing System ensures that every inch of the bowl is thoroughly cleaned with each flush. This results in an efficient and powerful flush that effectively removes waste, all with only a 1.28 GPF flushing capacity.
An enhancement to the Tornado flush is another standout feature of this TOTO Carolina II toilet – the CEFIONTECT glaze. This nano glaze creates an ultra-smooth surface that prevents waste from adhering to the bowl’s surface, which raises the Tornado flush efficiency in achieving a clean flush.
The flush valve, or drain valve (the name shown in TOTO’s parts list), is an improved variation of the flapper valve. Instead of a hinged flapper, it uses a seal resembling the canister valve, ensuring better water flow control and a more reliable flushing mechanism.
In addition to its performance-driven features, the TOTO Carolina toilet offers a 17.5 inches Universal Height bowl. This design complies with ADA standards, providing safer accessibility and comfort for users of varying mobility levels.
Last but not least, the toilet uses a Unifit rough-in adapter to connect the bowl to the closet flange. The advantage here is it offers the flexibility to adapt the toilet to all 3 rough-in sizes, which are 10″, 12″, and 14″.
You just need to specify the right adapter size when ordering the toilet. And even if you make a mistake with the rough-in size, just ask for an exchange for the correct adapter. There’s no need to ship back the entire toilet.
Bidet Seat Compatibility
This Carolina II toilet is ‘Specially designed to accommodate a TOTO WASHLET,’ says TOTO.
No doubt about it. If you observe the size and shape of the elongated seat, it matches to a T with the washlet. That’s a common shape for most bidet seats, like Brondell and Bio Bidet.
Another giveaway is the T40 bowl which has the feature to tuck away the bidet’s cable and water hose neatly from sight.
If you intend to install a TOTO washlet on this Carolina II low-profile toilet, do it. They should fit like they are made for each other. Or you may prefer another bidet seat brand; they should also look fine on this Carolina II. Just make sure to check the shape and dimension of the 3rd party bidet seat carefully if it is not a TOTO.
Conclusion: The TOTO Carolina toilet may not be the most visually striking option, but its focus on functionality and performance sets it apart. With signature features like the Tornado Flushing System and the CEFIONTECT glaze, it combines impressive functionality with acceptable elegance, making it a reliable and noteworthy choice for any bathroom.
There’s hardly any bone to pick here except the extremely subjective exterior. And it’s not the easiest to clean with the nooks and crevices under the tank. But not the hardest either, given its one-piece design with a rimless bowl.
And, of course, the trip lever flush mechanism is preferred over the push button when the space above the tank cover is rather restrictive.

Why Rimless Bowls Are Better Than Rimmed Bowls?
The main benefit of a rimless bowl is its ease of maintenance and superior bowl cleaning. Instead of water raining down the rim, a jet on one or both sides of the bowl allows water to rush out and spiral down, sweeping the whole bowl surface. It’s similar to a wipe-down that provides a more thorough bowl cleaning.
Rimless Bowl Flushing
Rimmed bowls, on the other hand, have crevices and hard-to-reach areas under the rim where bacteria and debris can accumulate, making them more difficult to clean effectively. And when the rim holes are blocked by debris, it will affect the flushing power and efficiency.
Newer toilets will come with a rimless bowl, as they are becoming popular with busy homeowners. So, if you have a choice, pick the rimless toilet. You will love it.
Disadvantages of Low-Profile Toilets
1. Flushing Power: One drawback of low-profile toilets is that their flushing power may not be as strong as taller toilets. This is mainly due to the lower water level in the tank, which can affect the force and effectiveness of the flush.
Hydrostatic Pressure – As water pressure is proportional to the depth of the water, the lower the level, the lesser water weight exerts on the water at the bottom. Therefore, there will be less pressure at the valve opening. As a result, the short-tank toilets may not handle large waste loads as efficiently as their regular height counterparts. Or thoroughly clean the bowl with a single flush.
If you observe the MaP rating of most low-height toilets, you will discover none has ever achieved the highest MaP 1000.
2. Replacement Parts: Due to the tank size and height (in particular), short-height toilets are unable to use standard parts. The flush and fill valves are usually shorter than those used in regular toilets. For this reason, it is more difficult to find compatible replacement parts when repairs or maintenance are needed.
Often times you will need to buy back the original parts from official vendors or manufacturers. And it’s not unusual to meet with long shipping times when the suppliers don’t have the ready stock because they are not common regular parts. Not to mention the higher cost for special orders, and even higher if you need it fast.
3. Hefty One-Piece Design: There is no such thing as a low-profile two-piece toilet. In other words, you will never see a two-piece toilet with an overall height of under 28 inches. That makes handling a huge chunk of porcelain challenging and arduous if you try to do the installation alone.
Even more challenging are those of the skirted design, where the flange bolts are not visible when you are trying to align the toilet into position.
What You Need to Consider Before Purchase
Before purchasing a low-profile toilet, several considerations will help you avoid making mistakes and zero in on the model that best meets your requirements and preferences. Here are the primary factors to consider:
1. Height Constraint
One of the primary reasons for choosing a low-profile toilet is to accommodate height constraints in your bathroom, such as under the window sill, countertop, storage rack, or cabinet. Measure the available space carefully to ensure that the low-profile toilet will fit comfortably within the designated space without obstructing other fixtures and blending well with your bathroom decor.
2. Pushbutton or Trip Lever
Give some thought to the type of flushing mechanism that best meets your needs. Some low-profile toilets feature a pushbutton flush, while others have a traditional trip lever. The choice will depend on where you are installing the toilet and if there’s any obstruction to the flush lever or button.
For instance, a trip lever will be more appropriate if the toilet is installed under a countertop with limited space above the tank lid.
So, practicality should come first if you have some vertical clearance to take care of. Or you will face inconveniences with the flush button every time you use the toilet.
3. Ease of Maintenance
At the minimum, you must be able to easily remove the tank lid and access the fill and flush valves for repairs or replacement, regardless of where the toilet is installed. You definitely wouldn’t want to remove the entire toilet just to replace the flapper or adjust the water level in the tank.
So, consider the space around the toilet carefully for the accessibility of internal components. Ideally, you should be able to look into the tank for visual cues of issues in your maintenance routine.
If there’s nothing much you can do to the space, for example, under the countertop, consider creating a removable section of the countertop. Your imagination and creativity will come in handy in such situations.
Additionally, consider features that allow easy cleaning, such as flat exterior surfaces and an open-rim design that helps prevent the accumulation of dirt and debris. This can impact the convenience and cost-effectiveness of future maintenance requirements.
4. Bidet Seat Compatibility
Unless you are certain you won’t need a bidet seat now and in the future, any model featured above is the right choice, limited only by your budget. Otherwise, choose the model that is, preferably, compatible with any bidet seat brands.
However, if you want a bidet seat from the start, study the requirements of the preferred one, then pick the compatible low-profile toilet. In most cases, the toilet must have at least a two inches clearance between the tank and seat bolts for a bidet attachment.
And those that have a French curve connecting the tank and bowl may not be a good fit for bidet seats. The curve may cause obstruction to the bidet for proper installation and break the butt-cleaning seat when you sit on it.
