A matte-black finish can turn a basic bathroom into a more considered space, but choosing a smart toilet involves matching plumbing, electrical access, and comfort features to your room. Some options add bidet functions and automatic sensors, while others focus on efficient flushing and one-piece styling.
Only a few choices combine dark finishes with true smart functions, so this roundup also flags important differences in fit and finish. You’ll find options for shared bathrooms, existing elongated toilets, compact powder rooms, and households that want extensive wash-setting control.
The Picks In Brief
KOHLER E835 White Bidet Seat
HOROW T37 Smart Toilet
Swiss Madison Sublime One-Piece Toilet
Swiss Madison St. Tropez Matte Black Toilet
EchosLife V02 Toilet
EchosLife V01MAX Toilet
The Picks, Examined More Closely
The KOHLER E835 turns a compatible elongated toilet into a more personalized washing setup without replacing the whole fixture. Its remote, heated seat, warm water, and adjustable spray controls make the most sense in a primary bath where regular use justifies a dedicated outlet and a more hands-on setup.
Unlike the integrated smart toilets that follow, this is a seat upgrade, which can make it more practical in a finished bathroom. Its white finish, however, won’t suit a design centered on matte-black fixtures.
Good Reasons To Consider
- Three spray modes, three nozzle positions, and adjustable water pressure make the washing routine easier to tailor.
- A hybrid heater supplies warm water continuously while five seat-temperature settings handle different preferences.
- Warm-air drying adds comfort and reduces the need to reach for a separate towel after washing.
- Three programmable remote presets save adjustments for household members who use the toilet regularly.
- The stainless-steel wand is rinsed before and after use, while electrolyzed water treats its surface.
Practical Considerations
- Installation requires a ground-fault circuit interrupter, or GFCI, electrical outlet and a compatible elongated bowl.
- The white finish differs clearly from the black finishes used in the Swiss Madison choices.
- Controls are more extensive than on a standard toilet, so wall placement for the remote deserves thought.
Key Specs
Built With In Mind
This seat suits someone with an elongated toilet who values heated comfort and detailed wash controls more than a matching black finish.
Where Another Pick Suits Better
The HOROW T37 Smart Toilet is the stronger match for a shared bathroom that needs a dark fixture, automatic lid movement, and sensor flushing.
Automatic lid movement gives the HOROW T37 a clear advantage in a busy shared bathroom, especially when several people use the same toilet throughout the day. The off-seat and foot sensors add another layer of hands-free operation, so contact with the flush control isn’t always necessary.
Rough-in refers to the distance from the wall to the toilet’s centerline, and this model uses a 10-inch configuration. That narrower measurement can help in older bathrooms, though you should compare it with the exact bowl footprint before replacing an existing unit.
Real Benefits
- Approach and departure sensors open and close the lid automatically, reducing repeated contact.
- Off-seat and foot flushing make the toilet practical for shared or high-traffic spaces.
- Warm water, adjustable pressure, and selectable washing modes support a more comfortable routine.
- A heated seat, warm-air drying, and a built-in night light improve comfort around the fixture.
The Fine Print
- The 10-inch rough-in must align with your existing drain and room layout.
- Confirm the exterior finish before ordering, since a “Blackout Flush” feature does not by itself establish the bowl color.
Feature Snapshot
Who It Suits Best
The T37 fits shared households that value automatic operation and have a 10-inch rough-in bathroom layout.
Another Choice May Suit
The EchosLife V01MAX Toilet is a closer fit for shared rooms seeking a broader collection of integrated wash and sensor functions.
The Sublime brings matte-black styling and two separate flush volumes to a straightforward one-piece toilet. It lacks the washing, heating, and automatic controls found in the smart models, making it a more focused choice for bathrooms where efficient flushing matters most.
Its low flush uses 1.1 gallons per flush, or gpf, while the full flush uses 1.6 gpf. You can choose between the two buttons according to the job, rather than relying on a single fixed volume every time.
The Helpful Details
- Separate 1.1 and 1.6 gpf buttons let you match water use to different needs.
- The one-piece profile and skirted trapway reduce exposed seams and simplify routine cleaning.
- Non-porous, scratch-resistant ceramic is practical for a heavily used family bathroom.
- The quick-release seat detaches for cleaning and returns with a gentle, quiet closing action.
Trade-Offs To Consider
- It has no integrated bidet washing, heated seat, warm-air drying, or automatic flushing.
- The 12-inch rough-in requires more clearance from the wall than the HOROW T37.
Made For
This toilet suits a design-conscious household that wants a matte-black fixture and selectable flushing without electronic bidet functions.
Look Elsewhere When
The KOHLER E835 White Bidet Seat fits better when warm-water washing and remote-controlled comfort matter more than fixture color.
The St. Tropez takes a quieter approach than the Sublime, using one 1.28 gpf flush instead of separate light and full buttons. That simplicity can make it easier for household members to operate, especially in a powder room where a quick, familiar control matters.
Its elongated bowl and one-piece matte-black form suit a modern bathroom, while the 14-inch rough-in calls for more space behind the fixture. For a narrow room, you may find the installation footprint less forgiving than the HOROW T37.
Notable Gains
- The matte-black finish gives dark bathrooms a coordinated focal point.
- A single 1.28 gpf flush keeps operation direct and uncomplicated.
- Non-porous, scratch-resistant ceramic supports straightforward everyday care.
Details To Watch
- The 14-inch rough-in must match the available space and existing plumbing location.
Technical Highlights
Right Fit For
This model is a practical match for a minimalist powder room with adequate rear clearance and no need for electronic washing features.
Reach For A Different Pick When
The Swiss Madison Sublime One-Piece Toilet is the better choice for separate flush-volume controls in a standard 12-inch rough-in space.
The EchosLife V02 focuses on a broad set of washing choices rather than emphasizing automatic lid movement. In a primary bathroom, you may appreciate the ability to shift among rear, feminine, moving, and softer water-and-air spray patterns throughout the day.
On-demand heating provides warm water without the need to wait for a tank, while adjustable temperature, pressure, and spray position make the system adaptable to different preferences. Compared with the KOHLER E835, the attraction here is the wider spray selection rather than remote presets.
Real-World Strengths
- Four spray patterns cover a broader range of washing preferences.
- On-demand warm water supports a more comfortable start to each use.
- Adjustable temperature, pressure, and spray position let multiple household members tailor the setup.
- The integrated one-piece format avoids the separate bidet-seat arrangement used by the KOHLER option.
Some Limits To Know
- Confirm the rough-in, water connection, and electrical requirements before this full fixture enters your renovation plan.
- Verify the exterior color on the product page because a dark finish is central to this category.
- The V02 does not foreground the automatic lid and seat sensors presented in the V01MAX.
Who Will Love This
The V02 suits someone who wants integrated bidet functions and several wash patterns in a primary or guest bathroom.
A Better Fit Elsewhere
The EchosLife V01MAX Toilet is the better fit for a shared room where automatic lid movement and sensor operation carry more weight than the number of wash patterns.
The EchosLife V01MAX is built around automation, with the lid and seat opening and closing as someone approaches or leaves. In a busy shared bathroom, you may find those responses more convenient than reaching for a handle, particularly at night.
It also brings the all-in-one format and quiet-flush positioning of the V01MAX together with a broad feature set. Unlike the V02, this model puts automatic movement at the center of the experience, so it makes the most sense when several people share the fixture.
Everyday Wins
- Automatic lid and seat movement reduces repeated contact with the fixture.
- Smart sensing supports a smoother transition into and out of the bathroom.
- The integrated design keeps the bidet and toilet functions in one unit.
- Quiet-flush positioning suits shared rooms where background noise matters.
- All-in-one construction can simplify the feature set you need to operate.
Where It May Fall Short
- Check the room dimensions and rough-in carefully because the integrated fixture requires a full replacement setup.
- Confirm the exterior finish, plumbing connection, and power requirements before ordering.
Quick Facts
The Right Fit
The V01MAX fits shared households seeking automatic lid movement, sensor responses, and an integrated bidet-toilet format.
Consider Something Else When
The HOROW T37 Smart Toilet is the more practical option when a 10-inch rough-in and compact layout matter more than the V01MAX’s broader automation focus.
What to Check Before Replacing a Toilet
Measure the Rough-In First
Rough-in is the distance from the finished wall to the toilet’s centerline. The HOROW T37 uses a 10-inch rough-in, the Swiss Madison Sublime uses 12 inches, and the St. Tropez uses 14 inches. Measure the available floor space and compare it with the replacement fixture before removing anything.
Decide Between a Seat and a Full Fixture
The KOHLER E835 is a bidet seat that fits over a compatible elongated toilet. The HOROW T37 and both EchosLife choices are complete smart toilets, which means the plumbing, power, and installation plan need to cover the entire unit. A seat upgrade can be less disruptive in a finished bathroom.
Check Power and Water Access
Bidet functions require a suitable water supply and electrical connection. The KOHLER seat specifically calls for a GFCI outlet, while integrated models need their own installation requirements checked. Position the fixture where plumbing and power can reach it without awkward extension cords or visible hoses.
Prioritize the Right Kind of Comfort
Heated seats, warm water, air drying, remote presets, automatic lids, and multiple spray patterns serve different preferences. A bathroom with frequent shared use may benefit more from sensor operation, while a personal suite may prioritize wash settings and temperature controls.
Avoiding Common Installation Surprises
Common Shopping Slip Ups
A dark fixture color is only one part of the decision. Confirm the actual bowl finish, seat shape, rough-in, and connection requirements, especially for a full replacement. A black-looking smart toilet that doesn’t fit the room’s footprint can become an expensive remodel.
What Separates Premium From Basic
Higher-tier models tend to concentrate more controls into the fixture, including heated seating, warm-air drying, programmable settings, and automatic movement. Those extras help in frequent-use bathrooms, while a basic one-piece toilet remains sensible when flushing control and simple styling are the priorities.
Frequently Asked Questions
Are all six options finished in black?
No. The Swiss Madison Sublime and St. Tropez have specified matte-black finishes, while the KOHLER E835 is white. Confirm the exterior finish for the other choices before ordering.
What does rough-in mean when replacing a toilet?
Rough-in measures the distance from the wall to the toilet’s centerline. Your existing measurement determines which of the 10-inch, 12-inch, and 14-inch configurations may fit.
Is a bidet toilet seat different from a smart toilet?
A bidet seat adds washing functions to a compatible existing toilet. A smart toilet combines the bowl, seat, flushing, and electronic functions as one complete fixture.
Does a black smart toilet need a nearby outlet?
Most electronic models need both water and electrical connections. The KOHLER E835 requires a GFCI outlet, and complete smart toilets also need their electrical requirements verified.
Which option works best in a shared bathroom?
The HOROW T37 and EchosLife V01MAX emphasize automatic lid movement and sensor-based operation. Their actual fit still depends on rough-in, plumbing, power, and room dimensions.
Final Verdict
The best fit depends on what your bathroom truly needs. A matte-black finish comes naturally from the Swiss Madison toilets, while sensor operation makes the HOROW T37 and EchosLife V01MAX more engaging for shared spaces. The KOHLER E835 wins on refined wash and heat controls, provided its white finish suits the room. Start with measurements, then choose the features that will matter after the novelty fades.
