A space-saving toilet can make a small bathroom feel less crowded, but “back-to-wall” can describe different setups. Some toilets sit on the floor with the tank hidden or tucked against the wall; wall-hung models suspend the bowl and need an in-wall carrier. The picks below include both types, plus compact floor-mounted alternatives. Check the installation requirements before you buy, especially whether the tank and carrier are included.

Our Picks: Best Space Saving Back To Wall Toilet reviews
1. DeerValley Compact One-Piece Toilet: Best Complete Floor-Mounted Pick
This DeerValley is a compact, floor-mounted one-piece toilet rather than a traditional concealed-tank or wall-hung model. Its round bowl and roughly 24.6-inch depth make it a practical option when you want to save room without rebuilding the wall to fit an in-wall carrier.
The toilet has a dual-flush system rated at 1.1 and 1.6 gallons per flush, a skirted exterior, and a soft-close polypropylene seat. The package includes installation parts such as a wax ring, bolts, and a wrench. Side-access panels are intended to make plumbing access easier, though this is still a floor-mounted installation that needs to suit your bathroom’s existing layout.
Its main trade-off is the standard-height seat, which may feel lower than the nearly 17-inch seat on the other DeerValley model below. It also does not provide the open floor area or concealed tank associated with a wall-hung toilet. Choose it if you want a compact, all-in-one floor toilet and do not need a true wall-hung design.
Pros:
- Compact round-bowl design with a depth of about 24.6 inches
- Dual-flush options and a skirted exterior
- Soft-close seat and installation accessories are included
- One-piece construction avoids a separate visible tank-and-bowl connection
Cons:
- Floor-mounted, so it is not a true wall-hung or concealed-tank toilet
- Standard seat height may not suit shoppers who prefer a taller seat
Verdict: Pick this DeerValley if you want a compact, ready-to-install floor toilet rather than a wall-hung system.
2. Swiss Madison Ivy Wall-Hung Toilet: Best for Adjustable Installation Height
The Swiss Madison Ivy is an elongated wall-hung bowl designed to pair with an in-wall tank carrier and actuator flush button. Suspending the bowl can free up visible floor space and make the area beneath it easier to clean. The carrier and actuator are sold separately, so this is not a complete, ready-to-install toilet by itself.
Its dual-flush setup offers a 0.8-gallon light flush and a 1.6-gallon full flush. The carrier’s legs allow the installer to adjust the bowl height, and the listing gives a 500-pound weight capacity. The elongated ceramic bowl offers more room than the round bowls on the compact DeerValley floor models.
The biggest practical consideration is the extra planning and installation work. You’ll need a compatible carrier, in-wall tank, and flush actuator, as well as a wall structure designed for the system. Its listed bowl dimensions are about 20.65 inches deep by 14.75 inches wide, but the complete installation also depends on the carrier and finished wall.
Pros:
- Wall-hung design can open up floor space beneath the bowl
- Elongated shape and adjustable installed height
- Two flush choices, including a 0.8 GPF light flush
- Quick-release, soft-close seat is included
Cons:
- Requires a separate in-wall carrier system and actuator
- Installation is more involved than replacing a floor-mounted toilet
Verdict: Choose the Ivy when you are planning a wall-hung installation and want an adjustable-height bowl, but budget for the separate carrier and flush components.
3. Swiss Madison Cascade Back-to-Wall Bowl: Best Minimalist Wall-Mounted Option
The Cascade is listed as a back-to-wall elongated toilet bowl, while its product details specify wall-mounted installation. In practice, treat it as a bowl for a wall-hung system, not as a complete floor-mounted toilet with a concealed tank. The supplied information lists the bowl and seat, so confirm which carrier, tank, and flush components are needed before ordering.
Like the Ivy, it offers 0.8 and 1.6 GPF flush options and an elongated shape. The listing also describes a removable flush plate for plumbing access. That access can be helpful for servicing an in-wall system, but the plate and compatible system components need to be part of your installation plan.
The product information provides little detail about its overall dimensions, so measure your intended space and compare the bowl and carrier specifications with your installer’s plan. Unlike the complete DeerValley toilets, this option is best considered during a remodel where the wall and plumbing can be set up for a wall-mounted bowl.
Pros:
- Elongated wall-mounted bowl for a streamlined look
- Dual-flush options of 0.8 and 1.6 GPF
- Removable flush plate is described as providing plumbing access
- Seat is included in the listed package contents
Cons:
- Product information does not establish that the in-wall tank and carrier are included
- Dimension details are limited, so confirm fit before purchase
Verdict: The Cascade is a good candidate for a planned wall-hung setup, provided you verify the required system parts and installation dimensions first.
4. DeerValley Compact 0.8/1.28 GPF Toilet: Best for a Higher Seat
This compact DeerValley is another floor-mounted, one-piece option rather than a true back-to-wall or wall-hung toilet. It projects about 24.6 inches from the wall and has a round bowl, making it a useful choice for a tight bathroom that already uses a floor-mounted toilet connection.
Its dual-flush system is rated at 0.8 and 1.28 GPF. The seat height is listed at nearly 17 inches, which may be more comfortable than a standard-height bowl for people who find lower toilets difficult to use. A soft-close, removable seat, skirted trapway, and glazed ceramic surface are intended to make regular cleaning and seat maintenance easier.
The 12-inch rough-in is an important fit detail: check your existing measurement before ordering. The listed package includes a seat, water fitting, wax ring, floor bolts, and instructions. It is a stronger match than the wall-hung choices for a straightforward floor-toilet replacement, but it will not create the open floor underneath a suspended bowl.
Pros:
- Compact projection of about 24.6 inches
- Higher seat and round bowl in a small-footprint design
- 0.8/1.28 GPF dual flush
- Removable soft-close seat and skirted trapway
Cons:
- Floor-mounted rather than wall-hung or concealed-tank
- Requires a compatible 12-inch rough-in
Verdict: Choose this model if you want a compact floor toilet with a higher seat and your bathroom has the required rough-in.
5. Swiss Madison St. Tropez Concealed-Tank Bowl: Best for a Black Hardware Accent
The St. Tropez is a wall-hung toilet bowl intended for a concealed-tank look, with black hardware as its visual accent. Its listed dimensions are about 22.25 inches deep by 14.35 inches wide. The supplied product details identify a bowl and hardware, so check whether the compatible tank, carrier, and other components are included or must be purchased separately.
The elongated ceramic bowl has dual-flush options of 0.8 and 1.6 GPF, and the listing describes a 500-pound weight capacity. The wall-mounted format can leave the floor clear below the toilet, but it requires the right in-wall setup. That makes it less suitable as a simple replacement for a conventional floor-mounted toilet.
Compared with the Ivy and Cascade, the St. Tropez stands out for its black hardware and stated dimensions. The trade-off is that the available details do not confirm a complete installation package. Confirm the exact hardware and system compatibility with the seller or installer before committing.
Pros:
- Wall-hung design with an elongated bowl
- Black hardware adds a distinct finish detail
- Dual flush with 0.8 and 1.6 GPF options
- Listed dimensions help with early layout planning
Cons:
- Tank and carrier inclusion is not established in the supplied details
- Requires a compatible in-wall installation rather than a basic floor-toilet hookup
Verdict: Consider the St. Tropez if its black hardware suits your design and you have confirmed the complete concealed-tank system requirements.
How to Choose a Space-Saving Back-to-Wall Toilet
Know the difference between floor-mounted and wall-hung
A compact floor-mounted toilet keeps the bowl and tank in the room but uses a shorter footprint. A wall-hung toilet attaches to a carrier inside the wall, leaving open floor below the bowl. A concealed-tank design hides the tank behind the wall or a finished panel. Product names can use “back-to-wall” loosely, so check the listed installation method and included components rather than relying on the name alone.
Measure the rough-in and available depth
Measure from the finished wall to the center of the existing floor drain for a floor-mounted toilet. Compare that measurement with the model’s required rough-in; the compact DeerValley model in this list specifies 12 inches. For any toilet, check the bowl’s projection, width, and clearance around the sides and front. For wall-hung models, include the carrier and finished wall in your space plan.
Confirm what comes in the box
A bowl-only listing may not include the tank, carrier, actuator, or flush plate needed for a working installation. The Swiss Madison wall-hung options require particular attention to these components. By contrast, the DeerValley models list more floor-installation parts, such as a wax ring and floor bolts. Confirm the full bill of materials before you order to avoid delays or mismatched parts.
Choose a bowl shape and seat height
Round bowls generally take up less front-to-back space than elongated bowls, which can help in a very tight room. Elongated bowls provide more seating room but may need more clearance. Seat height also affects comfort: one DeerValley model is described as standard height, while the other is listed at nearly 17 inches. Consider who will use the bathroom and how much room you have.
Compare flush options and water use
Dual-flush toilets let you choose between a lower-volume flush and a fuller flush. The products here list different combinations, including 0.8/1.28, 0.8/1.6, and 1.1/1.6 GPF. Compare the exact figures for the model you select, and remember that flush performance also depends on correct installation and the connected system.
Plan for cleaning and future access
A skirted floor toilet has fewer exposed contours around its base, which can simplify wiping. Wall-hung bowls leave the floor beneath them accessible, but in-wall components still need a way to be reached for service. Some listed models describe removable flush plates or side-access panels. Check how the plumbing will be accessed before the wall is closed.
Consider installation scope before choosing a style
Replacing a floor-mounted toilet is usually a different project from installing a wall-hung unit with an in-wall carrier. A wall-hung setup may require changes to the wall structure, plumbing, and finished surfaces. If you are not already remodeling, compare the full installation plan—not just the bowl’s dimensions—against a compact one-piece toilet.
Frequently Asked Questions
What is the difference between a back-to-wall toilet and a wall-hung toilet?
A back-to-wall toilet usually sits on the floor with its rear close to the wall, often with the tank concealed or positioned behind a panel. A wall-hung toilet suspends the bowl from a carrier inside the wall. Check each product’s installation method because product titles may use these terms differently.
Do wall-hung toilets come with the tank and carrier?
Not always. The Swiss Madison Ivy listing says the in-wall carrier system and actuator are sold separately. For the Cascade and St. Tropez, the supplied details identify the bowl and some accessories but do not establish that the full in-wall system is included. Verify the package contents before ordering.
Which option is easiest to fit in a small bathroom?
The compact DeerValley floor models are listed at about 24.6 inches deep and do not require a wall-hung carrier. A wall-hung toilet can free up floor area, but it needs a compatible in-wall installation. The best fit depends on your room measurements, plumbing, and willingness to remodel.
Are elongated toilets too large for small bathrooms?
Not necessarily, but they often take up more front-to-back room than round bowls. Measure the available depth and check the product dimensions along with required clearance. The round DeerValley models may be easier to fit in a particularly tight space.
What rough-in does the compact DeerValley toilet require?
The compact DeerValley model with the 0.8/1.28 GPF flush is listed with a 12-inch rough-in. Measure from the finished wall to the center of the floor drain and confirm that your bathroom matches before buying.
Which pick is best if I want a higher seat?
The DeerValley compact model with the 0.8/1.28 GPF flush is described as having a seat height of nearly 17 inches. Compare that with the standard-height DeerValley option and the installation height options available for the Swiss Madison Ivy carrier system.
Can I replace a regular floor toilet with a wall-hung model?
It may be possible, but a wall-hung model needs a compatible carrier, tank, plumbing, and suitable wall installation. It is not usually a direct swap for a standard floor toilet. Ask a qualified installer to assess the room before purchasing the bowl.
Final Recommendation
For a straightforward small-bathroom replacement, the DeerValley compact 0.8/1.28 GPF model is the strongest fit if your rough-in is 12 inches and you want a higher seat. If your renovation is already planned around an in-wall carrier, the Swiss Madison Ivy offers adjustable height and an elongated bowl, while the Cascade and St. Tropez provide other wall-hung design options. In every case, confirm measurements and complete system components before ordering.
