The American Standard Colony ADA compliant elongated complete toilet refers to specific configurations within American Standard’s Colony collection that combine a Right Height (chair-height) elongated bowl with a manufacturer-listed ADA-compliant design, sold as a complete package with the tank, bowl, and other core components included. American Standard offers multiple Colony configurations, so the exact height, flush rate, rough-in, and included parts depend on the specific model number — this guide focuses on the well-documented Colony model 751AA001.020, a two-piece, 1.6 GPF elongated toilet with a 12-inch rough-in.
Before buying or installing a Colony toilet, it helps to evaluate your bathroom’s accessibility needs, available floor space, existing rough-in measurement, water-use preferences, and which components you actually need included. Getting these details right up front prevents a mismatched purchase or a difficult installation day.
What Is the American Standard Colony ADA Compliant Elongated Complete Toilet?
The Colony collection is one of American Standard’s long-running toilet lines, offering practical, no-frills bathroom fixtures across several bowl shapes and heights. “Elongated” describes the bowl shape — an oval-front design that is longer front-to-back than a round-front bowl, generally offering more seating surface for adults.
“Complete toilet” means the product is sold as a full package rather than just a bowl or just a tank. For the verified 751AA001.020 model, American Standard lists the complete package as including the tank, bowl, a color-matched seat, a wax ring, and color-matched bolt caps.
“Right Height” is American Standard’s branding for a taller bowl design, intended to make sitting down and standing up easier — a feature that overlaps with, but is not automatically identical to, ADA compliance. This configuration can be a practical option for homeowners who want a taller seat, an elongated bowl shape, and fewer separate parts to buy, but the specific model still needs to match your bathroom’s existing rough-in and space.
What Does ADA Compliant Mean for the Colony Toilet?
ADA compliance, in the context of toilets, generally relates to seat height and other dimensional standards intended to make fixtures easier to use for people with mobility limitations. American Standard’s own product listing for the 751AA001.020 states that its Right Height bowl is ADA compliant.
It’s important to understand what that claim covers and what it doesn’t. A toilet being ADA compliant refers to the fixture itself — not the entire bathroom. Full ADA bathroom compliance, particularly in commercial or public settings, also depends on factors like clear floor space, grab bar placement, door width, and surrounding clearances, which are separate from the toilet model itself. For any project involving legal ADA compliance requirements — such as a rental property, public facility, or commercial space — check the applicable ADA standards and local building codes rather than relying on the toilet alone to satisfy the full requirement.
What Does Right Height or Chair Height Mean?
“Right Height” and “chair height” both describe a toilet bowl that sits taller than older standard-height toilets, generally intended to be closer to the height of a standard chair for easier sitting and standing. For the Colony 751AA001.020 model specifically, American Standard lists a 16-1/2-inch rim height.
It’s worth understanding the difference between a few related measurements:
- Bowl rim height — the height of the porcelain bowl itself, which is the 16-1/2 inches listed for this model
- Seat height — the final height once the seat is installed, which can add a small amount on top of the rim height depending on the seat design
- Overall toilet height — the total height including the tank, which is a separate measurement from seat height
If seat height is a critical factor for your household, it’s worth checking the assembled height with the seat installed rather than relying on the bowl rim measurement alone.
Why Choose an Elongated Bowl?
An elongated bowl shape offers more front-to-back seating area compared with a round-front bowl, which many adults find more comfortable. This shape has become common in modern U.S. bathrooms and is often paired with Right Height configurations like this Colony model.
That said, elongated bowls aren’t automatically the better fit for every bathroom:
- They require more front-to-back floor space than round-front bowls
- Very small or tightly laid out bathrooms may find a round-front bowl easier to fit around doors, vanities, or fixtures
- Door swing and cabinet clearance should be measured against the bowl’s total projection before purchasing
Elongated isn’t universally more comfortable for every user — it’s a trade-off between seating space and the extra room it needs in the bathroom.
American Standard Colony Toilet Specifications
The specifications below are based on American Standard’s official listing for model 751AA001.020. Other Colony configurations (standard height, round-front, one-piece, or different rough-ins) will differ — always verify the specific model you’re considering.

Note: this specific model is listed as discontinued on American Standard’s site as of this writing, meaning it may only be available through remaining retailer stock. Confirm current availability before planning a purchase around it.
Is the American Standard Colony Toilet Really ADA Compliant?
For the specific 751AA001.020 configuration, American Standard’s own product page states that the Right Height bowl is ADA compliant. That is a manufacturer claim tied to this exact model and configuration — it does not automatically extend to every toilet sold under the broader “Colony” name, since the collection includes standard-height and other non-ADA configurations as well.
It’s also worth repeating: an ADA-compliant toilet does not by itself make a bathroom ADA compliant. Installation height, surrounding clearances, grab bar availability, door width, and other layout factors all play a role in overall bathroom accessibility. If ADA compliance is a legal requirement for your project, review the official ADA accessibility standards directly rather than relying on a single fixture’s marketing claim.
How Much Water Does the Colony Toilet Use?
The 751AA001.020 model is listed at 1.6 gallons per flush (6.0 liters per flush), often written as 1.6 GPF. This figure describes how much water the toilet uses per flush cycle — a meaningful number when comparing against older toilets, many of which used 3.5 gallons per flush or more before federal water-efficiency standards tightened.
This model is not identified in American Standard’s listing as WaterSense certified — some other Colony configurations use a lower 1.28 GPF rate, which is closer to the WaterSense-eligible range. If EPA WaterSense certification matters to your purchase decision, check the EPA WaterSense product search directly, since that certification applies to specific models rather than to the Colony line as a whole.
How Well Does the American Standard Colony Toilet Flush?
American Standard lists a MaP score of 800g for the 751AA001.020 model. MaP (Maximum Performance) testing is a standardized, third-party method for measuring how much solid waste a toilet can clear in a single flush, and it’s commonly used across the plumbing industry to compare flush performance between models. An 800g score reflects strong performance under standardized test conditions, but it’s a lab measurement — not a guarantee against every real-world clog, which can also depend on what’s flushed, water pressure, and drain-line condition.
This model’s 2-inch flush valve and 2-inch trapway are also cited by the manufacturer as contributing to its flush strength and clog resistance. Together with the 1.6 GPF flow rate, these are the components most directly tied to flushing performance on this configuration.
What Does “Complete Toilet” Include?
For the 751AA001.020 model, American Standard’s official listing states the complete package includes:
- Tank
- Bowl
- Wax ring
- Color-matched seat
- Color-matched bolt caps
Included components can vary meaningfully across different Colony models — some “less seat” configurations don’t include a seat at all, and not every listing includes a wax ring. Always check the exact product listing for your chosen model before assuming a specific part is in the box. A water supply line is not confirmed as included with this model, so plan to have one on hand separately.
What Rough-In Does the Colony Toilet Need?
Rough-in refers to the distance from the finished wall behind the toilet to the center of the floor bolts or waste outlet, and it’s one of the most important measurements to get right before buying a toilet. Twelve inches is the most common rough-in in U.S. homes, and it’s the measurement listed for the 751AA001.020 model.
Measure from the finished wall — meaning the wall surface itself, not the baseboard trim, which can throw off the measurement by an inch or more. Not every Colony toilet uses a 12-inch rough-in; some configurations are built for 10-inch rough-ins, so confirm the number on your specific model rather than assuming.
American Standard Colony Elongated Toilet Dimensions and Bathroom Fit
Beyond rough-in, several other measurements matter for a comfortable, functional fit:
- Bowl projection (front-to-back distance from the wall)
- Overall toilet height, including the tank
- Overall width
- Tank clearance from the wall
- Door swing clearance
- Cabinet or vanity clearance
- Side clearance from adjacent fixtures or walls
- Front clearance for standing and sitting space
- Supply-line location relative to the toilet’s connection point
These exact figures should come from the specification sheet for your chosen model rather than being assumed from a similar-looking toilet. Even small differences in bowl projection can affect door clearance in a tight bathroom.
How to Install an American Standard Colony Toilet
This is a general overview. Always follow the manufacturer’s specific installation instructions for your exact model.
Step 1: Verify the rough-in. Confirm the toilet’s rough-in matches your bathroom’s existing waste outlet measurement before beginning.
Step 2: Shut off the water. Close the toilet’s supply valve, usually located on the wall behind the toilet.
Step 3: Remove the existing toilet, if replacing one. Drain the tank and bowl, then disconnect the supply line.
Step 4: Prepare the flange. Inspect the closet flange and surrounding floor for damage before proceeding.
Step 5: Install the new wax ring or approved sealing system. If you’re replacing an old toilet, you’ll first need to remove the old seal — see how to remove a toilet wax ring for that process. Then follow the manufacturer’s specific guidance for placing the new one.
Step 6: Position the toilet bowl. Carefully align the bowl over the mounting bolts and lower it into place.
Step 7: Secure the bowl. Tighten the mounting hardware evenly and carefully — porcelain can crack under excessive force.
Step 8: Install the tank, if two-piece. Follow the manufacturer’s tank-to-bowl assembly instructions.
Step 9: Install the seat. Use the included seat if the model comes with one.
Step 10: Connect the water supply. Reattach the supply line to the fill valve.
Step 11: Test the toilet. Check for leaks, confirm proper tank fill, test flush performance, and make sure the bowl sits stable on the floor.
This overview is not a substitute for the official American Standard installation manual for your specific model.
Common Installation Mistakes to Avoid
- Measuring the rough-in incorrectly, or measuring from the baseboard instead of the finished wall
- Installing over a cracked or damaged closet flange
- Reusing an old, compressed wax ring
- Overtightening porcelain mounting bolts
- Failing to check that the toilet sits level on the floor
- Dealing with a loose or spinning mounting bolt — see why do Oatey flange bolts spin freely if you run into this during installation
- Skipping the post-installation leak check
- Assuming every component is included without checking the listing
- Installing without reviewing the model-specific manual
- Ignoring door, cabinet, or side clearance requirements
- Using replacement parts not intended for this specific model

Common Colony Toilet Problems and Troubleshooting
Toilet Keeps Running
Often caused by a worn flapper or flush valve seal, a faulty fill valve, or a water level set too high in the tank. If you’re comparing flush valve replacement procedures across brands, Kohler’s K3489 flush valve replacement instructions offers a useful reference for the general process, though always follow American Standard’s own parts and instructions for this toilet.
Weak Flush
Can result from a low tank water level, a partially clogged trapway, a worn internal flush valve, or reduced water supply pressure.
Toilet Rocks
Usually points to an uneven bathroom floor, an improperly seated installation, or an issue with the closet flange height.
Toilet Leaks at the Base
Commonly caused by a failed wax ring seal, a damaged or misaligned flange, or an installation issue that didn’t create a proper seal.
Tank or Bowl Is Cracked
Cracked porcelain generally can’t be reliably repaired and typically needs replacement of the affected component. Don’t attempt to diagnose the cause or extent of a crack without a physical inspection.
When Should You Call a Plumber?
Consider professional help when:
- The closet flange is damaged or needs replacement
- The subfloor around the toilet shows damage
- The toilet still rocks after a careful, level installation
- There’s a persistent leak at the base that reinstallation doesn’t fix
- The installation requires unusual plumbing modifications
- The supply line or shutoff valve is damaged
- Your existing rough-in doesn’t match the toilet you’ve purchased
- You’re not comfortable removing or installing the toilet yourself
- You suspect a broader sewer or drain-line issue
Frequently Asked Questions
Is the American Standard Colony toilet ADA compliant?
