Our Picks: Best Wall Hung Toilet Supports reviews
1. BAR Industries SK1000U Buttress Retrofit Support: Best for a Compatible Retrofit
This part is described as a buttress retrofit support for the BAR Industries SK1000U system. It is not presented as a complete concealed tank carrier, so it makes the most sense when you already have a compatible installation and need the specific support part.
The supplied product details do not provide dimensions, load capacity, included hardware, or a compatibility list beyond the SK1000U reference. That makes careful model matching especially important. Confirm the part number and installation requirements with the seller or manufacturer before relying on it for a project.
Compared with the full carrier systems below, this is a narrower, retrofit-focused option. The listing data also marks it unavailable, so check whether it can be obtained before building your project plan around it.
Pros:
- Made for a BAR Industries SK1000U retrofit setup
- May suit repairs where a full carrier replacement is unnecessary
- Listed as a wall-mounted toilet support part
Cons:
- Product details do not state capacity, dimensions, or included components
- Compatibility appears limited to a specific system
Verdict: Consider this part only if you have confirmed that your existing BAR Industries setup uses the SK1000U-compatible support.
2. Swiss Madison SM-WC424: Best for a Concealed Dual-Flush Setup
The SM-WC424 is a concealed in-wall tank carrier designed for a wall-hung toilet. Its steel frame supports the bowl, while the tank sits inside the wall for a cleaner look around the bathroom. The listing describes a dual-flush system and a frame that allows a range of mounting heights.
Swiss Madison lists a weight capacity of 500 pounds and adjustable carrier legs for setting the desired height. The wall-hung bowl and faucet are sold separately, so this is a carrier system rather than a complete toilet package. Before ordering, verify that your chosen bowl and bathroom layout work with the carrier’s dimensions and mounting requirements.
Its stated capacity and adjustable height make it a straightforward option to compare with the Eridanus and MEJE systems. The supplied listing data marks it unavailable, so confirm availability before selecting it.
Pros:
- Concealed tank design for a streamlined appearance
- Steel frame with adjustable carrier legs
- Listed weight capacity of 500 pounds
- Dual-flush system
Cons:
- Wall-hung bowl and faucet are not included
- Listing data marks the product unavailable
Verdict: This is a useful option to investigate if you want a concealed dual-flush carrier and have confirmed compatibility with your bowl and wall layout.
3. Eridanus Dual-Flush Carrier: Best for a 2×4 Stud Wall
Eridanus combines a concealed tank carrier with a dual-flush system and flush plate. The listing specifies 0.8 and 1.6 GPF flush options, and describes an adjustable frame height from 0 to 200 mm. The wall-hung bowl is not included and must be purchased separately.
The system is listed for 2×4 stud walls, with the product description also stating that it fits stud and solid walls. Because those wall types need different anchoring approaches, confirm the correct mounting method and required framing for your specific installation rather than assuming the same hardware works for both.
Compared with the Swiss Madison SM-WC424, the Eridanus listing gives a specific flush volume and says a flush plate is included. It does not provide a stated weight capacity, so buyers who need that figure should confirm it before purchase.
Pros:
- Includes the carrier system and dual-flush plate
- Listed 0.8/1.6 GPF flush options
- Adjustable frame height
- Described as compatible with most wall-hung toilets
Cons:
- Wall-hung toilet bowl is sold separately
- Product details do not state a weight capacity
Verdict: Choose the Eridanus if its wall requirements match your project and you want a carrier with a specified dual-flush setup and included plate.
4. Swiss Madison SM-WC326: Best for a Back-to-Wall Toilet
This Swiss Madison carrier is included as a related support option, but its listed use is for a back-to-wall toilet—not a typical wall-hung bowl. The distinction matters: a back-to-wall toilet rests on the floor, while a wall-hung toilet is supported by its carrier and sits above the floor.
The SM-WC326 is specified for 2×6 commercial studs and has a steel frame with adjustable height. Swiss Madison lists its capacity as 500 pounds. The back-to-wall toilet is sold separately, and the supplied listing data marks this carrier unavailable.
For a true wall-hung installation, the Eridanus, SM-WC424, or MEJE carrier is a closer match based on the supplied product descriptions. Choose this model only if your toilet is the back-to-wall type and the framing matches its stated requirements.
Pros:
- Steel frame with adjustable height
- Listed 500-pound capacity
- Designed for 2×6 commercial studs
Cons:
- Made for a back-to-wall toilet, not a typical wall-hung bowl
- Toilet is sold separately, and listing data marks the carrier unavailable
Verdict: This is not the right pick for most wall-hung toilet projects; consider it only when your toilet and framing match the listed back-to-wall setup.
5. MEJE MZE014P Carrier: Best for a Higher Listed Weight Capacity
The MEJE MZE014P is a concealed carrier and tank system with a chrome dual-flush actuator plate. It is listed for installation in 2×6 wood or steel studs. The manufacturer describes compatibility with its MZE014P smart wall-hung toilet and says the carrier works with most wall-hung toilets, but it is still important to check the dimensions and connection requirements for your specific bowl.
The system offers listed flush options of 1.7 GPF and 0.9 GPF and an adjustable height of up to an additional 7¾ inches. MEJE states a maximum supported weight of 880 pounds. That figure is a product specification, not a substitute for following the installation instructions or confirming that your wall framing and mounting method are suitable.
Unlike the Eridanus, which is listed for 2×4 studs, this system calls for 2×6 framing. Its included actuator plate and higher stated capacity may suit some projects, but its stud requirement can rule it out if the wall is already framed differently.
Pros:
- Includes the concealed carrier and dual-flush actuator plate
- Listed capacity of 880 pounds
- Adjustable height of up to an additional 7¾ inches
- Front actuator plate provides access to the tank and valves
Cons:
- Specified for 2×6 wood or steel studs
- Toilet bowl is not included; compatibility should be confirmed
Verdict: The MEJE is worth considering when your project has compatible 2×6 framing and you want an included dual-flush plate with a high stated capacity.
How to Choose a Wall-Hung Toilet Support
Match the Carrier to Your Toilet Bowl
Start with the exact toilet model you plan to install. A carrier may be described as compatible with most wall-hung toilets, but that does not confirm that every bowl will fit. Check the manufacturer’s specifications for connection points, mounting dimensions, and any required carrier model. Do not confuse a wall-hung toilet with a back-to-wall toilet, which rests on the floor.
Check Your Wall Framing
Confirm the required wall construction before buying. The Eridanus listing specifies 2×4 stud walls, while the MEJE and Swiss Madison SM-WC326 listings call for 2×6 framing. A retrofit support part may have its own system-specific requirements. If you have a solid wall or existing framing, get clear instructions for the correct mounting method rather than assuming a carrier will fit.
Understand What Is Included
Some products are carrier systems with a tank and flush plate; others are individual support parts. The Eridanus listing includes a dual-flush plate, and the MEJE listing includes a carrier system and actuator plate. The Swiss Madison SM-WC424 listing says the bowl and faucet are sold separately. Check the package contents so you can plan for any separate bowl, flush plate, or other components your installation needs.
Compare Capacity and Follow Installation Requirements
Some listings state a maximum supported weight, such as 500 pounds for the Swiss Madison carriers or 880 pounds for the MEJE system. The Eridanus and BAR Industries product details do not provide a capacity. Compare only stated specifications, and follow the manufacturer’s installation instructions; a capacity figure alone does not confirm that your wall or installation is suitable.
Consider Flush Options and Maintenance Access
Dual-flush systems offer two flush settings, but the listed amounts vary. Eridanus specifies 0.8/1.6 GPF, while MEJE specifies 0.9/1.7 GPF. Check which system fits your needs and whether the actuator plate provides access to the tank components. For concealed systems, access through the flush opening can be important when maintenance is needed.
Verify Availability and Replacement-Part Support
Availability can change, and the supplied product data marks several options unavailable. Check the listing before committing to a purchase. For a retrofit component like the BAR Industries part, confirm the exact model match and whether it is the correct replacement for your existing setup.
Frequently Asked Questions
What is a wall-hung toilet carrier?
A wall-hung toilet carrier is a frame-and-tank system installed behind the wall. It supports a wall-hung bowl and holds the concealed tank. The specific frame, bowl, and wall requirements depend on the product.
Are wall-hung and back-to-wall toilets the same?
No. A wall-hung toilet is supported off the floor by a carrier. A back-to-wall toilet rests on the floor, even if its tank or plumbing is concealed. The Swiss Madison SM-WC326 listing is for a back-to-wall toilet, so check the toilet type before choosing it.
Do these support systems include the toilet bowl?
Not all of them do. The Swiss Madison SM-WC424 and Eridanus listings say the bowl is not included. The MEJE listing describes the carrier package and its compatibility, but you should confirm the bowl and package contents for your exact order.
Can I use a 2×4 carrier with a 2×6 wall?
Do not assume that a carrier listed for one wall setup will fit another. Check the manufacturer’s installation requirements and confirm how the carrier is meant to attach to your framing before purchase.
Which option has the highest stated weight capacity?
The MEJE listing states a maximum supported weight of 880 pounds. The Swiss Madison SM-WC424 and SM-WC326 listings each state 500 pounds. The other supplied product details do not provide a capacity.
Is the BAR Industries part a complete carrier system?
The listing describes it as a buttress retrofit support part for the BAR Industries SK1000U. It does not provide details showing that it includes a tank or a complete carrier frame, so confirm exactly what is included before ordering.
Final Recommendation
For a complete concealed system, start by matching your toilet and framing to the Eridanus, Swiss Madison SM-WC424, or MEJE carrier specifications. The Eridanus is listed for 2×4 stud walls and includes a dual-flush plate; the MEJE is specified for 2×6 framing and has the highest stated capacity in this selection. Treat the BAR Industries part as a system-specific retrofit component, and avoid choosing the Swiss Madison SM-WC326 for a wall-hung bowl because it is listed for a back-to-wall toilet.
