Our Picks: Best Square One Piece Toilet reviews
1. Swiss Madison Concorde: Best for a 10-Inch Rough-In
The Swiss Madison Concorde is a useful option when your bathroom calls for a 10-inch rough-in. That measurement sets it apart from the other standard-flush models here, which are listed with 12-inch rough-ins. Confirm your existing plumbing measurement before ordering; a toilet that does not match your rough-in may not fit properly.
Its dual-flush buttons offer a 1.1-gallon light flush and a 1.6-gallon full flush. The square bowl gives the toilet a geometric look, while the one-piece ceramic body and skirted trapway keep the exterior lines clean. The product information also lists a fully glazed trapway, a soft-close seat, and a quick-release mechanism for removing the seat during cleaning.
This model is a good match if you want dual-flush operation and need a 10-inch rough-in. Its standard-height design is listed at 15–17 inches. One limitation is that the supplied listing data marks this configuration as unavailable, so confirm that it can be ordered before making it your choice. Its 10-inch rough-in also makes it a less direct replacement for a bathroom set up for a 12-inch model.
Pros:
- 10-inch rough-in option
- Dual flush with 1.1- and 1.6-GPF settings
- Skirted trapway and quick-release, soft-close seat
- Scratch-resistant, non-porous ceramic, according to the product description
Cons:
- Listing data indicates this configuration may not be available
- Requires a 10-inch rough-in, so it will not suit every bathroom layout
Verdict: Choose this Concorde if your plumbing has a 10-inch rough-in and you can confirm the model is available; otherwise, consider one of the 12-inch options below.
2. Swiss Madison Brusque: Best Dual-Flush 12-Inch Option
The Brusque is a straightforward choice if you want a square one-piece toilet with a standard 12-inch rough-in and dual-flush controls. You can choose between the listed 1.1-GPF light flush and 1.6-GPF full flush, rather than using the same flush setting every time.
The square bowl provides the angular look shared by the other Swiss Madison models in this list. Its skirted trapway hides the plumbing from view, and the product description specifies fully glazed ceramic and a soft-close, quick-release seat. The listed standard height is 15–17 inches.
Compared with the 10-inch Concorde, the Brusque is a more suitable fit for a 12-inch rough-in. Compared with the single-flush Concorde, it offers a choice of flush volumes. The trade-off is that this is not the right pick if you prefer a single control or need a different rough-in. Product dimensions beyond the rough-in are not provided here, so check the full listing and installation information against your bathroom before buying.
Pros:
- Dual-flush choice of 1.1 or 1.6 GPF
- Designed for a standard 12-inch rough-in
- Skirted trapway creates a smooth exterior for cleaning
- Soft-close seat detaches for cleaning
Cons:
- Not suitable for a 10-inch rough-in without confirming compatibility
- Its 1.6-GPF full-flush setting uses more water than the single-flush 1.28-GPF option in this roundup
Verdict: The Brusque is a strong fit for shoppers who want a 12-inch rough-in, a square profile, and the flexibility of dual flush.
3. Swiss Madison Concorde: Best Simple Single-Flush Pick
This Concorde uses a single-flush, right-side handle rather than the dual-flush buttons found on the Brusque and the brushed-gold Concorde. Its listed flush volume is 1.28 GPF, and the model is designed for a 12-inch rough-in. That makes it an option for shoppers who want a familiar handle instead of choosing between two flush buttons.
The square bowl and one-piece ceramic construction give it a modern, streamlined shape. Like the other Swiss Madison models here, it has a skirted trapway, a fully glazed passage, and a soft-close, quick-release seat. Its listed standard height is 15–17 inches.
The right-side handle is an important detail to check against your bathroom layout and preference before purchasing. This model also gives you less flush-setting flexibility than a dual-flush toilet. In return, it offers a simpler control layout and a lower listed flush volume than the dual-flush models’ full-flush setting.
Pros:
- Single 1.28-GPF flush with a right-side handle
- Designed for a 12-inch rough-in
- Skirted trapway and quick-release seat support easier exterior cleaning
- Square bowl and one-piece design
Cons:
- No choice between light and full flush settings
- Right-side handle placement may not suit every preference or layout
Verdict: Pick this Concorde if you want a 12-inch rough-in toilet with a simple handle and a listed 1.28-GPF flush rather than dual-flush controls.
4. BCANHOME Black Smart Toilet: Best for Integrated Bidet Features
The BCANHOME is the feature-focused option in this group. It combines a one-piece toilet with an integrated bidet system, heated seat, warm-water wash, and dryer. The description lists a 1.28-GPF flush, a 12-inch rough-in, and a matte-black square design.
Its hands-free features include an automatic lid, auto-flush when leaving, and a foot sensor; the description also lists knob and remote controls. Bidet functions include several wash modes, adjustable water temperature and pressure, a self-cleaning nozzle, and warm-air drying. These additions offer more options than the standard-flush Swiss Madison models, but also mean there is more to set up and operate.
This toilet requires a 110-volt plug-in power connection, as well as the listed 12-inch rough-in and NPT 1/2-inch angle valve. Plan for the electrical connection before installation, and confirm that the supplied accessories and installation instructions match your bathroom. Its black finish is a bold design choice, so it may be less versatile if you want a conventional white fixture.
Pros:
- Integrated bidet, heated seat, warm wash, and dryer
- Listed 1.28-GPF flush and standard 12-inch rough-in
- Multiple control methods and hands-free functions
- Distinctive matte-black square design
Cons:
- Requires a 110-volt power connection
- More functions and setup requirements than a standard toilet
Verdict: Choose the BCANHOME if you want an integrated bidet and comfort features and can accommodate the power and plumbing requirements.
5. Swiss Madison Concorde with Brushed Gold Hardware: Best Decorative Detail
This Concorde has the same core dual-flush setup as the Brusque, with a 1.1-GPF light flush and a 1.6-GPF full flush. It uses a standard 12-inch rough-in and adds brushed-gold hardware for a more decorative look. If you are coordinating fixtures or accents in a contemporary bathroom, that finish is the main reason to consider it over the standard-looking options.
The product description lists a square bowl, a skirted trapway, scratch-resistant non-porous ceramic, and a soft-close seat that detaches for cleaning. The listed standard height is 15–17 inches. These practical details match the other dual-flush Swiss Madison models, so the gold hardware—not a different flush system—is the key distinction.
Consider the color and finish alongside the rest of your bathroom fittings before choosing this model. It is also worth checking the full product listing for dimensions and included components, since those details are not specified in the supplied product information. If you do not need the decorative hardware, the Brusque offers a similar dual-flush feature set without that stated finish.
Pros:
- Brushed-gold hardware adds a distinctive design detail
- Dual flush with 1.1- and 1.6-GPF settings
- Designed for a standard 12-inch rough-in
- Skirted trapway and quick-release, soft-close seat
Cons:
- The gold finish may not coordinate with every bathroom
- Offers the same listed flush volumes as the Brusque, so the finish is the main differentiator
Verdict: Choose this Concorde if you want dual-flush operation in a square one-piece toilet and the brushed-gold hardware fits your bathroom design.
How to Choose a Square One-Piece Toilet
Match the Rough-In to Your Plumbing
Rough-in is the distance from the finished wall behind the toilet to the center of the floor drain. The models here include both 10-inch and 12-inch options, so do not assume they are interchangeable. Measure carefully and compare that measurement with the product listing and installation instructions before ordering. If you are unsure, ask a plumber to verify it.
Choose the Flush Style That Fits Your Routine
Dual-flush models let you select between a lower-volume light flush and a higher-volume full flush. In this group, the Swiss Madison dual-flush toilets list 1.1 and 1.6 GPF settings. The single-flush Concorde and BCANHOME are listed at 1.28 GPF. Think about whether you value having two flush choices or would rather use one straightforward control.
Check the Toilet’s Full Dimensions and Clearances
A rough-in measurement does not tell you the toilet’s overall width, depth, or height. Look up the full dimensions and compare them with the space available in your bathroom, including clearance around the bowl and room to open the door. A square shape can look different from a rounded bowl, so check the bowl and seat details as well as the overall footprint.
Consider Height and Seat Details
The Swiss Madison models in this list are described as standard height, between 15 and 17 inches. Check the listing for the exact height and whether the measurement refers to the bowl or seat. A soft-close seat can reduce closing noise, and a quick-release design makes it easier to remove the seat for cleaning. Confirm which components are included before purchase.
Think About Cleaning and Installation
A skirted trapway hides the exterior plumbing and gives the sides a smoother profile to wipe down. The Swiss Madison descriptions also specify a fully glazed trapway. These design details may make routine cleaning more convenient, but they do not replace checking the installation requirements. Review access-hole and hardware details, and consider professional installation if the plumbing or floor connection is unfamiliar.
Plan for Smart-Toilet Power Needs
The BCANHOME smart model includes powered features such as a heated seat, warm-water wash, dryer, and automatic functions. Its description specifies a 110-volt plug-in connection, along with a 12-inch rough-in and NPT 1/2-inch angle valve. Check that your bathroom can support the required connection before choosing it; a conventional toilet does not have the same electrical requirement.
Pick a Finish That Works with Your Bathroom
The Swiss Madison models have a clean, modern square profile, while the brushed-gold Concorde adds a specific hardware finish. The BCANHOME stands out with its matte-black look. Consider the finishes of your other bathroom fixtures and whether you want the toilet to blend in or serve as a prominent design feature.
Frequently Asked Questions
What is a square one-piece toilet?
It is a toilet with a square-style bowl and an integrated one-piece body. The models here combine that shape with features such as skirted trapways, dual-flush controls, or smart bidet functions, depending on the model.
How do I know whether I need a 10-inch or 12-inch rough-in?
Measure from the finished wall behind the toilet to the center of the floor drain, then compare the result with the product’s rough-in requirement. The first Concorde listed here is designed for a 10-inch rough-in; the other models specify 12 inches. Verify the measurement before ordering.
Is dual flush better than single flush?
It depends on your preference. Dual flush gives you a choice between the listed 1.1-GPF light flush and 1.6-GPF full flush on the Swiss Madison models. The single-flush Concorde uses a 1.28-GPF flush and has a simpler handle operation.
Which model has a heated seat and bidet?
The BCANHOME smart toilet includes a heated seat, bidet wash functions, warm-air drying, and other powered features. It requires a 110-volt plug-in connection, so account for that before installation.
Are the seats included with the Swiss Madison toilets?
The supplied product descriptions list soft-close seats with quick-release features for the Swiss Madison models. Check the current product listing to confirm what is included with the configuration you plan to buy.
Which option is best if I want the simplest controls?
The Swiss Madison Concorde with the right-side handle uses a single 1.28-GPF flush. It may suit you if you prefer a handle over dual-flush buttons, provided the handle location and 12-inch rough-in work for your bathroom.
Final Recommendation
For a standard 12-inch rough-in and flexible flush choices, the Swiss Madison Brusque is the most balanced option in this group. The single-flush Concorde is a better fit if you want a simple handle, while the BCANHOME is the clear choice for integrated bidet and heated-seat features—provided you have the required power connection. If your bathroom has a 10-inch rough-in, consider the 10-inch Concorde only after confirming that the configuration is available and matches your installation needs.
