Quick picks

3 Best bone finish
The only Bone White SUPERFLO listed in this pool, with a 21 inch extra tall seat height. It is one of two listings with a stated finish, and it is the option for bathrooms that need a bone fixture rather than a black one. The seller does not state a bowl shape, so this pick trades bowl certainty for color certainty.
Pros
- Stated Bone White finish, one of two stated finishes in the pool
- 21 inch extra tall seat height
- Listed for extra-tall use
Cons
- Seller does not state bowl shape
- Not a rear outlet, corner, or macerating configuration

Good fit if

- Tall-seat buyers who want a finish-specific model
Skip if
- You need a confirmed elongated bowl
- You prefer a black fixture
Verdict: The Bone White SUPERFLO is the finish-matched extra tall pick for this catalogue.
4 Best black finish
The only SUPERFLO in the pool with a stated black finish, sold as a 21 inch Comfort Height Toilet. It is the dark counterpart to the Bone White model and the pick when a modern or dark bathroom scheme still needs a tall bowl. The seller does not state a bowl shape, so color and height are the deciding features here.
Pros
- Stated black finish, one of two stated finishes in the pool
- 21 inch extra tall seat height
- Described as a comfort height toilet in the listing title
Cons
- Seller does not state bowl shape
- Not a compact, rear outlet, or macerating model
- No stated flush volume or WaterSense certification
Good fit if
- Modern bathrooms with black fixtures
- Buyers who want a tall toilet and a definite color
Skip if
- You need a bone white fixture
- You need a confirmed bowl shape
Verdict: The black 21 inch SUPERFLO is the color-specific tall toilet in this pool.
5 Best for seniors
The listing name points at the audience this toilet is built around: seniors who want less bending. Its stated specification is a 21 inch extra tall seat, the same tall height as the leading picks. With no bowl shape stated, it is the pick for height-first buyers rather than for shoppers who need a particular bowl style.
Pros
- 21 inch extra tall seat height
- Listing marketed directly for senior use
- Listed for extra-tall use in the catalogue
Cons
- Seller does not state bowl shape
- Not a compact, rear outlet, or macerating model
- No stated flush volume or WaterSense certification
Good fit if
- Older adults who have trouble lowering onto a standard seat
- Caregivers fitting a bathroom for easier standing up
Skip if
- You need a confirmed elongated bowl
- You are looking for a corner or rear outlet model
Verdict: The SUPERFLO Tall Toilets for Seniors is the senior-focused 21 inch pick in this guide.
6 Best 19 inch rear outlet
SUPERFLO Rear Outlet Toilet With 19 Inch Tall Toilet Rear Discharge
- Seat height
- Extra tall
This rear outlet SUPERFLO lists a 19 inch seat height, which makes it the only wall-discharge model in the pool with a stated dimension. It is not part of the 21 inch tall group, so it suits bathrooms where the wall outlet positioning matters more than maximum height. Buyers with wall plumbing can choose this one when a stated height is required.
Pros
- Rear outlet construction for wall-discharge plumbing
- Stated 19 inch seat height, the only rear outlet in the pool with a stated height
- Listed for extra-tall use in the catalogue
Cons
- Seller does not state bowl shape
- Height is lower than the 21 inch group, so it offers less of the tall-seat benefit
- No stated flush volume or WaterSense certification
Good fit if
- Wall-discharge bathrooms that need a known seat height
- Projects where a 21 inch bowl is too tall
Skip if
- You have a floor-mounted flange and standard plumbing
- You want the tallest available SUPERFLO seat
Verdict: The 19 inch rear outlet SUPERFLO is the wall-discharge pick with a number you can plan around.
7 Best rear outlet for seniors
This is the second rear outlet SUPERFLO in the pool and the one marketed to seniors. Unlike the 19 inch rear outlet model, the seller does not list a seat height or any other specification, so it works best when the exact dimension is not the deciding factor. If your wall plumbing is already set, this is the alternate rear outlet pick.
Pros
- Rear outlet construction for wall-discharge plumbing
- Listing name targets senior users
- Second rear outlet option in the pool
Cons
- Seller does not state any specifications, including seat height, bowl shape, or piece type
- No flush volume or WaterSense certification stated
- Without a stated height, it cannot be confirmed as tall as the 21 inch group
Good fit if
- Wall-discharge bathrooms where the exact height does not need to be specified
- Shoppers comparing two rear outlet SUPERFLO listings
Skip if
- You need a stated seat height
- You want a floor-mounted standard toilet
Verdict: The rear outlet SUPERFLO for seniors is the dimension-free wall-discharge alternative in this guide.
8 Best compact corner toilet
The compact corner toilet is the only SUPERFLO in the pool designed around a corner position and the only listing that states a two-piece construction. It still has an elongated bowl, which is a useful combination for a small footprint. It does not state an extra tall height, so it trades the tall-seat focus of the other picks for a space-saving layout.
Pros
- Compact corner design, unique in this pool
- Stated two-piece construction, unique in this pool
- Elongated bowl in a compact footprint
- One of three listings with a stated bowl shape
Cons
- No extra tall seat height stated
- Not a rear outlet or macerating model
- No stated flush volume or WaterSense certification
Good fit if
- Small bathrooms where a corner toilet saves floor space
- Buyers who want a two-piece build and an elongated bowl
Skip if
- You need a tall 21 inch seat
- You need a basement macerating system
Verdict: The 17.2 inch corner SUPERFLO is the compact, two-piece pick for tight spaces.
9 Best upflush for basements
The 750W listing is one of two macerating systems in this pool and the only one with a stated wattage in the product name. It is described as an upflush toilet for basements, which makes it the first choice when the drain line sits above the bathroom. The other macerating model offers a named description but no power figure.
Pros
- Macerating upflush design for basement installation
- Stated 750W figure, the only macerating model with a stated wattage
- Listing name targets basement use directly
Cons
- Seller does not state bowl shape or seat height
- No stated pump lift distance or installation requirements
- No flush volume or WaterSense certification stated
Good fit if
- Basements and below-grade bathrooms where gravity drainage is unavailable
- Buyers who want a power figure in the listing before installation
Skip if
- Standard floor-drain bathroom replacements
- You prefer the alternate upflush listing until its details are confirmed
Verdict: The 750W SUPERFLO upflush toilet is the basement pick with a stated wattage.
10 Best alternate upflush
SUPERFLO Macerating Toilet System Silent & Powerful Upflush Toilet
- Macerating (upflush)
- Yes
The second macerating listing has no stated wattage, unlike the 750W system, so it is the alternate when that power figure is not the deciding factor. The product name includes a Silent & Powerful description, but the seller does not state the wattage in the catalogue. It is still a macerating system and needs the same upflush planning as the other basement model.
Pros
- Macerating upflush design
- Listing name includes Silent & Powerful, a point of comparison with the 750W model
- Second upflush option when the 750W listing is not the right fit
Cons
- Seller does not state wattage, pump lift distance, or installation requirements
- No stated bowl shape or seat height
- No flush volume or WaterSense certification stated
Good fit if
- Basement installs where the alternate upflush listing fits the project
- Buyers who do not need a stated wattage in the product name
Skip if
- You need a concrete power figure
- You need a standard floor-drain toilet
Verdict: The Silent & Powerful SUPERFLO is the alternate upflush pick in this pool.

How the picks were chosen
How we picked: To build this guide we looked at the full SUPERFLO catalogue pool of 10 listings. We kept every listing because the pool is below the 12-pick floor and the listings span the main SUPERFLO configurations: extra-tall seats, an elongated corner toilet, two rear outlet models, and two macerating systems. Our selection rules used only the stated specifications: seat height, bowl shape, piece and outlet type, compact or macerating construction, and finish where named. We did not reward accessories, marketing phrases, or unstated features. Nobody on the site has used, installed, or flushed any of these toilets. Prices on the page are live prices read from the listing at the time the page is displayed, so they can change.
Picking the right one for you
Start with seat height
The extra tall SUPERFLO listings in this catalogue fall into two named height groups: 21 inch and 19 inch. The 21 inch models make up the larger group, and the 19 inch model is the rear outlet toilet. Taller seats reduce the bend required when sitting and standing, which is why several listings are marketed to seniors. If you want the tallest seat, aim for the 21 inch group; if space or outlet type matters more, the 19 inch rear outlet model is the smaller stated height.
Decide between round and elongated
Every SUPERFLO listing in this pool that states a bowl shape is described as elongated, and no round bowl appears in the catalogue. Elongated bowls give extra front-to-back space but can require more clear floor area. If the bathroom is tight, the 17.2 inch corner toilet is the compact model with an elongated bowl; if the seller does not state a shape, do not assume the bowl is elongated.
Know your drain outlet
The plumbing exit is one of the first things to check before buying a toilet. Floor-mounted toilets are standard for most bathrooms, and the SUPERFLO listings that are not described as rear outlet or macerating fall into that general floor-mounted group. The two rear outlet listings are built for wall-discharge plumbing. If your bathroom uses a floor flange, a rear outlet model will not be a direct fit, so measure the rough-in before ordering.
Consider a macerating unit for basements
Two SUPERFLO listings in this pool are macerating upflush systems, which grind waste and pump it through a discharge line instead of relying on gravity. These are the models to consider when the bathroom is below the sewer line or the drain is not in the floor. The 750W system is the only one with a stated wattage; the other is described as silent and powerful. Neither listing states pump lift distance, so verify that detail with the seller before installation.
Match the finish to the room
The SUPERFLO pool includes two listings with a stated finish: a 21 inch Bone White toilet and a 21 inch black toilet. Every other listing leaves the finish unstated, so color matching depends on the seller photos and details. If the toilet must match an existing fixture in bone or black, start with one of the two finish-specific listings; otherwise any of the height-focused models will work.
Check water efficiency and flush volume
EPA reports that toilets account for nearly 30 percent of indoor home water use, and WaterSense labeled toilets use 1.28 gallons per flush or less, 20 percent less than the federal standard. None of the SUPERFLO listings included here state a flush volume or a WaterSense label, so the listing details are the place to confirm efficiency before you buy.
Questions
What does extra tall mean on a SUPERFLO toilet?
The extra tall SUPERFLO listings in this catalogue are sold as 21 inch or 19 inch toilets, using the number in the product title. That advertised height is what separates them from a standard-height bowl, and it is the reason they are often marketed to seniors and tall users. The seller does not state a measured distance from floor to rim, so treat the model name as the height claim.
Are SUPERFLO toilets one-piece or two-piece?
Only the 17.2 inch Corner Toilet Elongated is explicitly described as a two-piece compact toilet in this pool. The other SUPERFLO listings do not state whether they are one-piece or two-piece. If the number of pieces matters for cleaning, installation, or appearance, check the listing details or ask the seller before ordering.
What is a macerating toilet?
A macerating toilet grinds waste and pumps it to a drain line, so it does not rely only on gravity to move material. SUPERFLO's two macerating listings are the 750W Upflush Toilet for Basement and the Silent & Powerful Upflush Toilet System. These are a common fit for basements or bathrooms below the main sewer line, but the seller does not state installation requirements in the catalogue.
What is a rear outlet toilet?
A rear outlet toilet discharges waste through a connection in the wall behind the toilet instead of through a floor flange. SUPERFLO offers two rear outlet listings in this pool: one sold as a 19 inch tall toilet and one marketed for seniors. If your plumbing comes out of the wall, a rear outlet model is the matching type; if it comes out of the floor, it may not fit.
Do SUPERFLO toilets meet WaterSense?
The SUPERFLO listings in this pool do not state WaterSense certification or a flush volume, so this guide cannot confirm that any of them carry the label. EPA's WaterSense program sets efficiency and performance criteria for toilets; labeled models use 1.28 gallons per flush or less, which is 20 percent less than the federal standard. If water efficiency matters, confirm a stated flush volume or certification in the listing before buying.
How do the two macerating systems differ?
Both macerating listings are upflush systems, but only one is named as a 750W unit. The other is described as Silent & Powerful and does not have a wattage stated by the seller. If a power figure or pump capacity matters for your installation, the listing without a wattage figure will need more fact-checking before you commit.
