A wall-hung toilet can free up visible floor space and give a bathroom a cleaner look, but choosing a square bowl takes extra care: not every wall-mounted model specifies a square shape. Of the options below, the Swiss Madison Bastille is the only one explicitly described as square. The other picks offer useful wall-hung or smart-toilet features, but check their bowl shape, measurements, and installation requirements before ordering.

Best Square Bowl: Swiss Madison Bastille Wall-Hung Toilet
The Swiss Madison Bastille is the clearest match for shoppers who specifically want a square wall-hung toilet. Its square bowl is described as having a wide seating area, and the durable ceramic bowl comes with a Slymm soft-close, quick-release seat. The quick-release design can make seat removal more convenient when you need to clean around the hinges.
This is a bowl package, not a complete wall-hung toilet system. The concealed tank, supply line, and wall actuator are sold separately, so you will need to select compatible parts and plan for the in-wall installation. Bolts and screws needed for installation are included, and the product has a one-year limited warranty.
Compared with the other options here, the Bastille is the most direct choice for a square shape and a simpler feature set. It does not include the smart bidet functions or tank carrier found with some alternatives. Before buying, confirm the bowl’s measurements and compatibility with your chosen concealed tank and carrier.
Pros:
- Explicitly described as a square bowl
- Wide seating area
- Soft-close, quick-release seat included
- Installation bolts and screws included
Cons:
- Concealed tank, supply line, and wall actuator are sold separately
- Check system compatibility and measurements before ordering
Verdict: Choose the Bastille if a square bowl is your priority and you are prepared to source the compatible concealed tank components separately.
Best Feature-Rich Option: DeerValley Wall-Hung Smart Bidet Toilet
The DeerValley is a wall-hung smart toilet with an integrated water tank and pump-assisted system. Its feature set includes an automatic lid, auto flush, rear and front wash settings, oscillating wash, adjustable water temperature and pressure, a heated seat, and warm-air drying. The listing also describes a foam shield intended to help reduce splashing and waste adhesion.
The built-in tank and reinforced wall-mounted bracket are presented as an alternative to a traditional in-wall tank. That may appeal if you want a wall-hung setup without choosing a separate concealed tank, but it is still important to check the installation requirements and available bathroom space with the seller or installer. The pump-assisted design is also described as suitable for homes with low water pressure.
This model offers more comfort and automation than the Bastille or Eridanus, but its bowl shape is not specified in the supplied product information. If a square silhouette is essential, confirm that detail before purchase rather than assuming it from the wall-hung design. Its many functions may also be more than you need if you mainly want a basic square bowl.
Pros:
- Built-in tank and pump-assisted system
- Includes bidet wash, heated seat, and warm-air drying features
- Automatic lid and flush functions
- Listing describes a foam shield and power-outage flushing
Cons:
- Square bowl shape is not specified
- Feature-rich design calls for careful installation planning
Verdict: Consider the DeerValley if smart bidet functions and a built-in tank matter more to you than a confirmed square bowl shape.
Best Complete Wall-Hung Kit: Eridanus Toilet with 2×6 Carrier
The Eridanus package combines a wall-hung toilet bowl with a 2×6 in-wall tank carrier system. It also includes the cover and seat, dual-flush plate, and mounting accessories. Compared with the Bastille, which requires you to buy key concealed-tank components separately, this package lists more of the wall-hung system in one purchase.
The bowl is rimless, and the listing describes a double-jet dual-flush system that creates a swirling flush. A soft-closing seat is included, while the carrier allows the seat height to be adjusted during installation. The wall-mounted design leaves the floor below the bowl open, which can make that area easier to clean.
The product information does not specify that the bowl is square, so confirm its shape if that is a must-have. Also check the carrier’s fit with your bathroom’s wall framing and planned plumbing before ordering. It is a more practical choice for someone seeking a conventional dual-flush setup than for someone looking for smart bidet features.
Pros:
- Includes the toilet, seat, carrier system, flush plate, and mounting accessories
- Rimless bowl and dual-flush design
- Adjustable seat height during installation
- Wall-hung design leaves the floor below open
Cons:
- Square bowl shape is not specified
- Requires a compatible 2×6 in-wall installation
Verdict: Pick the Eridanus if you want a wall-hung kit with a carrier and dual-flush setup, but verify the bowl shape and wall fit first.
Best Smart Features on Paper: MJEE Wall-Mounted Smart Bidet Toilet
The MJEE combines a wall-mounted bowl and in-wall carrier with smart bidet functions. The listed features include dual-user memory, automatic lid operation, a foot sensor, a self-cleaning nozzle, a heated seat, and a night light. Its built-in tank and dual-pump system are described as designed to support flushing in homes with low or unstable water pressure.
The product description states that its steel carrier supports more than 500 pounds and that its flush uses 1.25 gallons per flush. It also lists a backup battery box for flushing during power outages and identifies the product as DOE and CEC certified. These are manufacturer-provided specifications; confirm the details and installation requirements with the seller before making a decision.
The key drawback is availability: the supplied listing data marks this model unavailable. Its bowl shape is also not specified, so it is not a confirmed square-toilet choice. If it becomes available, compare its installation needs and smart features with the DeerValley before choosing between them.
Pros:
- Dual-user memory for selected bidet and comfort settings
- Built-in tank and dual-pump flush system
- Backup battery box is listed for flushing during power outages
- Product description lists DOE and CEC certification
Cons:
- Listing data marks the product unavailable
- Square bowl shape is not specified
Verdict: Keep the MJEE on your shortlist only if its smart features suit your needs and the listing becomes available; it is not the safest immediate pick for a square bowl.
How to Choose a Square Wall-Hung Toilet
Confirm the bowl is actually square
Wall-hung describes how a toilet is mounted, not the shape of its bowl. Check product photos, measurements, and the seller’s specifications for a clearly stated square profile. In this selection, only the Swiss Madison Bastille is explicitly described as square. The other models may suit your wall-hung plans, but their listed details do not confirm a square bowl.
Check the full system, not just the bowl
A wall-hung toilet needs a secure support system and a compatible tank and flush setup. Some products include a carrier or integrated tank, while others sell important components separately. For example, the Bastille requires a separately purchased concealed tank, supply line, and wall actuator. Make sure you know exactly what is included before comparing packages.
Match the carrier to your wall and plumbing
In-wall carriers need to fit the bathroom’s framing and planned plumbing. The Eridanus listing specifies a 2×6 in-wall tank carrier, while the MJEE description names an in-wall carrier and the DeerValley describes a reinforced bracket with a built-in tank. Have an installer confirm the system fits your wall and that the waste outlet and water connections align with the product.
Measure the bowl and plan the seat height
Compare the bowl’s dimensions with your available room, nearby fixtures, and the space needed for comfortable use. For wall-hung models, seat height is set during installation, and some products describe adjustable height. Confirm the manufacturer’s measurements and the installer’s recommended finished height before the wall is closed.
Choose the features you will use
A basic bowl and soft-close seat may be enough if you mainly want a clean, floating look. Rimless designs and dual flush may appeal if easier bowl cleaning or flush options are priorities. Smart models add functions such as bidet washing, heated seats, automatic lids, and drying, but they also call for more careful planning. Confirm power and service requirements for any electronic model with the manufacturer or installer.
Consider maintenance and replacement parts
Think about how you will reach the tank and other concealed components if service is needed. Check what access the system provides, whether replacement parts are available, and which seat or flush components are compatible. For a smart toilet, also consider whether you are comfortable maintaining electronic and wash functions as well as the bowl itself.
Review what is included and the warranty
Package contents can vary. Check whether the seat, carrier, tank, flush plate, mounting hardware, and actuator are included or sold separately. The Bastille listing specifies a one-year limited warranty; warranty details for the other picks are not provided here, so confirm them before buying.
Frequently Asked Questions
Which option here is confirmed to have a square bowl?
The Swiss Madison Bastille is the only product in this selection explicitly described as a square toilet bowl. The other listings do not specify their bowl shape, so verify with the seller if you are considering one of them.
Does the Swiss Madison Bastille include the concealed tank?
No. Its description says the concealed tank, supply line, and wall actuator are sold separately. The listed package includes the bowl, seat, and installation bolts and screws.
Is a wall-hung toilet harder to install than a floor-mounted toilet?
Installation involves a support system and concealed tank or integrated tank arrangement, so planning is important. The exact work depends on the model and your bathroom’s wall framing and plumbing. Have a qualified installer confirm the setup before purchase.
Which option includes a carrier system?
The Eridanus listing includes a 2×6 in-wall tank carrier system, dual-flush plate, and mounting accessories. The MJEE listing also describes an in-wall carrier, but its supplied listing status is unavailable.
Which models have smart bidet functions?
The DeerValley and MJEE descriptions list bidet wash and other smart features. The DeerValley listing includes functions such as adjustable wash settings, a heated seat, and warm-air drying. The MJEE description lists bidet settings and dual-user memory, but its listing is marked unavailable.
Can I adjust the seat height on a wall-hung toilet?
Seat height is set during installation. The Eridanus and DeerValley descriptions mention adjustable height. Confirm the allowed range and your preferred finished height with the product details and installer.
Final Recommendation
For a toilet that is specifically confirmed to have a square bowl, the Swiss Madison Bastille is the clearest choice in this group. Its main trade-off is that you must source the concealed tank, supply line, and wall actuator separately. If an included carrier and dual flush matter more than a confirmed square shape, consider the Eridanus. For smart bidet features, compare the DeerValley with your installation needs, and treat the MJEE as an option to revisit only if it becomes available.
