Our Picks: Best In The Wall Toilet reviews
1. Eridanus Wall Hung Toilet: A Complete 2×6 Carrier System
The Eridanus is a wall-hung toilet system that comes with a bowl, seat, in-wall tank carrier, dual-flush plate, and mounting accessories. Its carrier is designed for a 2×6 wall, so confirm that your planned installation can accommodate that configuration before ordering.
The rimless bowl and floating design are practical features as well as style choices. With the bowl off the floor, you can clean beneath it, while the rimless shape is intended to reduce hard-to-reach areas inside the bowl. A double-jet flush is designed to create a swirling action, and the included soft-close seat helps avoid a loud slam.
This is a strong option if you want a coordinated bowl-and-carrier package rather than sourcing those parts separately. The trade-off is that you’ll need to plan carefully around the wall structure and service access. The listing does not state a gallons-per-flush figure, so compare the flush system with your water-use priorities before choosing.
Pros:
- Includes the bowl, seat, carrier, flush plate, and mounting accessories
- 2×6 in-wall tank carrier is specified
- Rimless bowl and floating design can make cleaning easier
- Dual flush and soft-close seat are included
Cons:
- Confirm wall framing and installation requirements before purchase
- The supplied details do not list flush volumes
Verdict: Choose the Eridanus if you want a rimless wall-hung toilet with its carrier system included and your wall is suited to a 2×6 installation.
2. Los Flexi Comfort & Elongated Wall Hung Toilet: Adjustable Height
The Los Flexi combines an elongated ceramic bowl with an adjustable tank carrier. Its listed height adjustment range is 0 to 7⅞ inches, giving you room to set the bowl position to suit the installation and the people who use it. Check the product instructions and finished-floor measurements to understand the final seat height you can achieve.
Its dual-flush system is specified at 0.8 and 1.6 gallons per flush. The soft-close seat has a quick-release feature, which can make removing the seat for cleaning or maintenance more convenient. The glossy white finish and elongated shape keep the design familiar, despite the wall-mounted installation.
This system stands out if bowl height and seat access are important in your decision. It also lists a two-year warranty. As with any in-wall system, you’ll need to plan for a suitable carrier installation and future access to the concealed components. The supplied product details do not specify all installation measurements, so verify them before committing.
Pros:
- Elongated ceramic bowl
- Carrier adjustment range of 0 to 7⅞ inches
- Dual-flush settings of 0.8 and 1.6 GPF
- Quick-release, soft-close seat and a stated two-year warranty
Cons:
- Confirm final bowl height and rough-in details with the installation instructions
- Concealed carrier components require a maintenance-access plan
Verdict: The Los Flexi is a good fit if you want an elongated bowl, adjustable mounting height, and clearly stated dual-flush volumes.
3. MEJE Wall Hung Smart Toilet Combo: Bidet and Automatic Features
The MEJE is more than a basic wall-hung toilet. The package includes a built-in water tank and in-wall carrier frame, along with a bidet seat and remote controls. Its wash functions include rear, feminine, and child modes, with adjustable nozzle position, water temperature, and pressure.
Comfort and convenience features include a heated seat, warm-air drying, and a nozzle that self-cleans before and after use. The toilet also lists automatic lid and flush functions, a foot sensor, and ambient lighting. Some automatic settings can be turned on or off, and sensor distance can be adjusted according to the product description.
Those features make this the most specialized option in the group. Before buying, check the full installation instructions and confirm that the setup works for your bathroom, including any power requirements and the space needed for controls. The supplied details do not provide a flush-volume figure, so shoppers focused on water use should ask the seller or check the complete listing specifications.
Pros:
- Includes a built-in tank and in-wall carrier frame
- Bidet functions offer adjustable position, temperature, and pressure
- Heated seat, warm-air drying, and self-cleaning nozzle
- Automatic lid and flush functions, with settings that can be adjusted
Cons:
- Has more functions and controls to set up than a standard toilet
- The supplied details do not state flush volume or all installation requirements
Verdict: Pick the MEJE if bidet washing and smart conveniences matter more to you than keeping the system simple.
4. TOTO RP Wall-Hung Toilet: Dual-Max Flush and CEFIONTECT Glaze
This TOTO package pairs a D-shaped wall-hung bowl with a DuoFit in-wall tank system and copper supply. Its Dual-Max flush offers 0.9- and 1.28-GPF options, while the mounting height adjusts from 15 to 19 inches. The listing also states that the wall-mounted design saves up to 9 inches of floor space compared with a standard floor-mounted toilet.
The bowl uses TOTO’s CEFIONTECT glaze, which is described as an exceptionally smooth surface intended to help reduce waste sticking to the ceramic. A D-shaped SoftClose seat is included. Together, these features make the system a straightforward choice for shoppers who want a wall-hung design with defined flush volumes and adjustable mounting height.
The supplied product data marks this option as unavailable, so confirm availability before planning a purchase. It is also important to verify that the tank system and bowl dimensions suit your project. Compared with the MEJE, this TOTO setup is less focused on smart features; compared with the Eridanus, it provides specific flush volumes and a stated mounting-height range.
Pros:
- Dual flush with 0.9- and 1.28-GPF options
- Adjustable mounting height from 15 to 19 inches
- Includes a D-shaped SoftClose seat
- CEFIONTECT glaze is designed to help limit waste sticking to the ceramic
Cons:
- The supplied product data marks it as unavailable
- Confirm system compatibility and availability before planning an installation
Verdict: Consider the TOTO if its flush settings, adjustable height, and glaze appeal to you, but verify that the complete system is available before choosing it.
5. Fine Fixtures In-Wall Toilet Combo Set: A Bundled Dual-Flush Option
The Fine Fixtures combo set includes a toilet bowl, soft-close seat, wall-hung tank and carrier system, and push buttons. Its mounting height has up to 3.5 inches of additional adjustment, according to the supplied product details. The bowl is fully glazed and has a wide trap-way opening.
The dual-flush system is listed at 1.1 gallons for a partial flush and 1.6 gallons for a full flush. The product description also highlights its StormOn washdown jets and says the set includes mounting hardware and step-by-step installation instructions. Those details make this a useful package to compare if you want the main system components in one set.
One point to weigh is that its stated flush volumes differ from the lower figures listed for the Los Flexi and TOTO options. Its adjustable range is also described differently, so compare the actual bowl-height measurements in the installation guide rather than relying on the adjustment figure alone. Even with instructions included, a wall-hung system needs careful planning for the carrier and concealed tank.
Pros:
- Includes the bowl, seat, tank, carrier, push buttons, and mounting hardware
- Dual-flush settings of 1.1 and 1.6 GPF
- Up to 3.5 inches of additional mounting-height adjustment is specified
- Soft-close seat and step-by-step installation instructions are included
Cons:
- Flush volumes are higher than the listed settings for the Los Flexi and TOTO options
- Confirm the final mounting height and installation fit before purchase
Verdict: The Fine Fixtures set is worth considering if you want a bundled carrier-and-bowl package with stated flush volumes and installation instructions.
How to Choose an In-Wall Toilet
Check the carrier and wall construction
A wall-hung toilet relies on a carrier frame to support the bowl and hold the concealed tank. Check whether the product includes the carrier, which wall construction it is designed for, and what the installation guide requires. For example, the Eridanus listing specifies a 2×6 carrier. Have your installer confirm that the framing and wall cavity can accommodate the system before you order.
Plan for access to the concealed tank
The tank and plumbing sit inside the wall, so maintenance access matters. Review how the flush plate or service opening provides access to internal parts, and make sure that arrangement suits your bathroom design. A neat finished wall should not leave you without a practical way to reach components that may need adjustment or repair.
Choose a mounting height that works for you
Seat height depends on the carrier setting and the finished floor, not just the bowl alone. Some product listings provide an adjustment range, but that number does not replace checking the installation dimensions. Compare the manufacturer’s mounting instructions with the height you want, and account for flooring that has not yet been installed.
Compare flush volumes and flush type
Dual-flush systems let you choose between two flush settings. The Los Flexi lists 0.8 and 1.6 GPF, the TOTO lists 0.9 and 1.28 GPF, and the Fine Fixtures set lists 1.1 and 1.6 GPF. Other options in this group do not state flush volumes in the supplied details. Compare the numbers and confirm the complete specifications if water use is a priority.
Decide which bowl and cleaning features matter
An elongated bowl, a D-shaped bowl, and a rimless bowl each offer a different design. Consider the available bathroom space and the shape you prefer. Features such as a quick-release seat, smooth glaze, or rimless design may also affect how you clean the toilet, but they do not replace checking the bowl’s dimensions and care instructions.
Consider smart features and power needs
A basic dual-flush system is simpler than a toilet with automatic opening, sensors, a heated seat, and bidet functions. If you choose a smart model like the MEJE, check the full specifications and installation instructions for any electrical and control requirements. Think about whether you will use the extra functions and whether you want the added setup and maintenance considerations.
Confirm what comes in the box
Included parts vary. Some listings specify a bowl, seat, carrier, tank, flush plate, or mounting hardware, while other systems may bundle several of those items together. Make a list of what your installation requires, then compare it with the product’s complete included-components list to avoid missing a required part.
Frequently Asked Questions
Do wall-hung toilets save bathroom space?
They can free up visible floor space because the bowl is mounted to the wall and the tank is concealed. The amount of space saved depends on the specific system and bathroom layout. The TOTO listing, for example, states savings of up to 9 inches compared with a standard floor-mounted toilet.
Does a wall-hung toilet include its in-wall carrier?
It depends on the product. The Eridanus, MEJE, TOTO, and Fine Fixtures descriptions specify a carrier or carrier system. The Los Flexi description refers to an adjustable tank carrier. Check the exact package contents before ordering, and confirm that the carrier fits your planned installation.
Can you adjust the height of a wall-hung toilet?
Some systems allow the carrier to be set at different mounting heights. The Los Flexi lists an adjustment range of 0 to 7⅞ inches, while the TOTO lists a mounting height range of 15 to 19 inches. These figures describe different measurements, so consult each installation guide to determine the finished seat height.
Are wall-hung toilets harder to install?
They require careful planning because the carrier and tank are concealed in the wall, and the carrier must be installed correctly before the wall is finished. The Fine Fixtures listing includes step-by-step instructions, but an installer should still confirm framing, plumbing, measurements, and access requirements for the specific model.
Which option has the lowest stated flush volume?
Of the products with flush volumes listed in the supplied details, the Los Flexi has the lowest stated partial-flush setting at 0.8 GPF. The TOTO lists 0.9 GPF for its lower setting, and Fine Fixtures lists 1.1 GPF. Check the complete product specifications before making a final choice.
What is the difference between a standard wall-hung toilet and a smart model?
A standard system focuses on the bowl, concealed tank, carrier, and flush controls. The MEJE adds bidet washing, a heated seat, warm-air drying, automatic lid and flush functions, and other controls. Those features may be useful if you want more convenience, but they also make setup more involved.
Final Recommendation
For a straightforward wall-hung system with a 2×6 carrier, rimless bowl, and included components, the Eridanus is a well-rounded place to start. Choose the Los Flexi if adjustable mounting height and stated dual-flush volumes are key priorities. The MEJE is the feature-rich pick for shoppers who want integrated bidet functions, while the TOTO is worth checking for its specific flush settings and glaze if it is available. Before buying any option, confirm the carrier fit, final bowl height, package contents, and access for maintenance.
