A Brief History of American Standard

The company traces its lineage to 1875, starting as the Standard Sanitary Manufacturing Company. By 1929, it had become the world’s largest producer of sanitary ware.

The brand has evolved significantly since then. Following a merger in 2008 and an acquisition by the Lixil Group in 2015, American Standard now operates with massive global resources. Today, they combine American design heritage with Japanese engineering precision.

Is American Standard a Good Brand?

Yes, American Standard remains a top-tier choice for homeowners. Their toilets are known for balancing affordability with commercial-grade durability.

The brand consistently ranks high for parts availability; you can find a flapper or seal for an American Standard toilet at almost any hardware store. In 2015, Builder magazine even ranked them number one for brand familiarity in bathroom accessories.

Who Makes American Standard Toilets?

American Standard is owned by the Lixil Group, a global housing and building materials leader. While the headquarters are in the US, manufacturing takes place in various locations globally, including Mexico, China, and the United States.

What to Look For

The catalog is huge, so picking the right model requires focusing on a few specific specs. Here is what you need to know before buying.

Single Flush vs. Dual Flush

Federal law changed in 1992, mandating that toilets use no more than 1.6 gallons per flush (GPF). This killed off the old 3 to 6-gallon water guzzlers. Today, you have two primary options for managing water usage.

Single Flush

These models use a consistent amount of water every time you press the lever, usually 1.28 or 1.6 GPF.

  • Simplicity: Fewer moving parts usually mean fewer repairs down the road.
  • Ease of use: You pull the handle, and it works; there is no guesswork for guests.

Dual Flush

Dual flush toilets feature two buttons or a two-stage lever. They typically offer 0.8 to 1.0 GPF for liquids and 1.28 to 1.6 GPF for solids.

  • Efficiency: You can save thousands of gallons of water a year.
  • Maintenance: The flush mechanism is slightly more complex to replace than a standard flapper.

Flushing Systems

American Standard is famous for its proprietary flush technologies. Here is the breakdown of their main systems:

  • VorMax: This system eliminates standard rim holes. Instead, it injects water into the bowl to create a whirlpool effect that scrubs the surface clean.
  • Champion: Known as the “clog stopper,” this system features a massive 4-inch flush valve (the industry standard is 2 to 3 inches) to move water faster.
  • Cadet: A reliable mid-range system with a 3-inch flush valve and a 2.125-inch trapway.
  • LXP: Often found on luxury models, this offers a standard 3-inch valve but is tuned for specific one-piece designs.

Look for a MaP (Maximum Performance) rating when shopping. A score of 1,000g means the toilet can flush 1,000 grams of solid waste in a single go.

One-Piece vs. Two-Piece Toilets

The mechanics are usually identical, so this decision comes down to aesthetics and cleaning.

One-Piece

The tank and bowl are fused into a single unit.

  • Hygiene: There is no gap between the tank and bowl for urine or dust to collect.
  • Style: They generally look sleeker and more modern.
  • Installation: They are heavier to lift because you cannot separate the parts.

Two-Piece

The tank bolts onto the bowl separately.

  • Cost: These are almost always cheaper to manufacture and ship.
  • Maintenance: If the tank cracks, you can replace just the tank rather than the whole toilet.

Rough-In Distance

The “rough-in” is the distance from the wall behind the toilet to the center of the floor bolts.

  • Standard: 12 inches is the standard for 90% of modern homes.
  • Older Homes: You might encounter 10-inch or 14-inch rough-ins.

Important: Measure from the finished wall, not the baseboard. If you buy the wrong size, the toilet will not fit.

Bowl Shape

Your bathroom layout often dictates the shape you need.

  • Elongated: Oval-shaped and extends about 2 inches further into the room. It is generally more comfortable for adults.
  • Round-Front: A circular bowl that saves space. It is the best choice for tiny powder rooms or tight clearances where a door might hit the toilet.

Toilet Height

Seat height significantly impacts comfort and accessibility.

  • Standard Height: The rim is about 15 inches off the floor. This is better for children or shorter adults.
  • Right Height / Chair Height: The rim is 16.5 to 17 inches high (plus the seat). This meets ADA guidelines and makes sitting down and standing up easier for taller people and seniors.

Budget Expectations

You do not need to spend a fortune to get a reliable flush.

  • $150 – $250: Solid two-piece toilets like the Cadet or Colony lines. Excellent performance, basic looks.
  • $300 – $500: One-piece designs, skirted trapways (easier cleaning), and advanced flushing systems like the Champion.
  • $600+: Designer aesthetics, tankless electric models, and integrated bidet features.

Product Reviews

Finding the right hardware is tough when the product names all sound the same. We scoured the catalog to select our favorite 7 models, rating them on flushing power, ease of cleaning, and overall value.

American Standard Right Height Studio S Low Profile Toilet

Best American Standard Low Profile Toilet

The Studio S is for homeowners who want their bathroom to look like a modern spa. It features a skirted trapway, meaning the sides are completely smooth, eliminating those annoying dust-catching curves found on standard toilets.

The “tankless” design is the real standout here. It connects directly to your supply line and uses a PowerFlo system to purge the bowl quietly and efficiently using just 1.0 gallon per flush. Because there is no bulky tank, it saves vertical space, making it perfect for placing under windows or shelving.

It features a “Right Height” bowl (16.5 inches) and an elongated shape, so it is comfortable for most adults. Just keep in mind that the high-end aesthetic comes with a high-end price tag.

Pros

  • Tankless design saves vertical space.
  • PowerFlo technology is quiet and efficient.
  • Skirted sides make cleaning incredibly easy.
  • ADA-compliant seat height.

Cons

  • Significantly more expensive than standard models.
  • Electric mechanism requires more complex maintenance.

American Standard Champion 4 Elongated One-Piece Toilet

Best American Standard Elongated Toilet

The Champion 4 is widely regarded as the muscle car of toilets. Its claim to fame is the massive 4-inch flush valve, which is roughly double the size of a standard valve. This allows water to rush into the bowl with tremendous force, virtually eliminating clogs.

In fact, American Standard claims it can flush a bucket of golf balls. While you probably won’t be testing that, it gives you peace of mind for daily use. It is a one-piece unit, so you don’t have to worry about a tank-to-bowl gasket leaking.

It uses 1.6 GPF, so it isn’t the most water-frugal option on the list, but it gets the job done in one go. The surface features the EverClean glaze, which inhibits the growth of stain and odor-causing bacteria.

Pros

  • Huge 4-inch flush valve prevents clogs.
  • One-piece design prevents leaks between tank and bowl.
  • Slow-close seat included.
  • 10-year warranty is excellent for the industry.

Cons

  • Uses 1.6 GPF (not WaterSense certified).
  • Heavy unit to move during installation.

American Standard Compact Cadet 3-Flowise Toilet

Best American Standard One-Piece Toilet

The Cadet 3 strikes a smart balance between size, power, and price. This “Compact” version offers an elongated bowl for comfort but fits it into the footprint of a round-front toilet. If you have a small bathroom but hate small toilet seats, this is the solution.

It uses an oversized 3-inch flush valve, which provides a faster, stronger flush than the standard 2-inch valves found on basic models. It sips just 1.28 gallons per flush, making it WaterSense certified and eligible for rebates in some municipalities.

It is a one-piece unit, which usually commands a higher price, yet the Cadet 3 remains surprisingly affordable. The trade-off is often the seat quality; many users opt to replace the included plastic seat with a sturdier third-party option.

Pros

  • Compact design fits elongated comfort in small spaces.
  • WaterSense certified (1.28 GPF).
  • Oversized 3-inch flush valve for strong performance.
  • EverClean antimicrobial surface.

Cons

  • Included seat feels a bit flimsy.
  • Accessing the bolts for installation can be tight.

American Standard Right Height Elongated Toilet

Best American Standard ADA Compliant Toilet

If accessibility is your priority, the Colony Right Height is a strong contender. The rim sits 16.5 inches off the floor, meeting ADA requirements. This extra height makes a world of difference for seniors or anyone with knee or back issues.

Despite being a budget-friendly option, it comes as a one-piece unit. This gives it a cleaner look and simplifies the cleaning process since there are fewer crevices for grime to hide in. The low-profile tank is also a nice touch, making the room feel slightly larger.

It uses 1.28 GPF to save on water bills. The main drawback here is the warranty; at just 2 years, it is significantly shorter than the coverage provided on the Champion or Cadet lines.

Pros

  • ADA-compliant chair height for easy access.
  • Water-efficient 1.28 GPF.
  • Low-profile tank looks modern.
  • One-piece construction is easy to clean.

Cons

  • Short 2-year warranty.
  • Flush is decent but not as powerful as the Champion line.

American Standard H2Option Dual Flush Toilet

Best American Standard Dual Flush Toilet

The H2Option is all about flexibility. It puts you in control of your water usage with a chrome-plated actuator button on top of the tank. You can choose a light 0.92-gallon flush for liquids or a standard 1.28-gallon flush for solids.

This toilet uses a siphonic jet system to maintain a clean bowl even with low water volume. The jet-fed rim power-washes the sides every time you flush. It holds the highest possible MaP rating, capable of moving 1,000 grams of waste, which is impressive for a high-efficiency model.

This is a two-piece model, so installation involves bolting the tank to the bowl. Note that this specific model is “Normal Height” (15 inches), so it is not considered ADA compliant.

Pros

  • Dual flush saves maximum water.
  • MaP Score of 1,000g ensures strong performance.
  • EverClean surface inhibits bacteria growth.

Cons

  • Standard height (15 inches) isn’t for everyone.
  • Two-piece design has a seam that catches dust.

American Standard H2Option Normal Height Round Toilet

Best American Standard Chair Height Toilet

This variation of the H2Option features a round-front bowl. Why choose round? It saves about 2 inches of depth compared to an elongated bowl. That might not sound like much, but in a cramped powder room or a bathroom where a door swings inward, those inches are critical.

Like its sibling, it features dual-flush technology (0.92/1.28 GPF) and the PowerWash rim to keep the bowl hygienic. It is a fantastic utility toilet for guest baths or smaller apartments.

The catch with this model is that the seat is often sold separately. You will need to budget an extra $30 to $50 for a high-quality round seat to complete the installation.

Pros

  • Round front is ideal for small bathrooms.
  • Ultra-high efficiency saves on utility bills.
  • PowerWash rim cleans effectively with less water.

Cons

  • Seat is usually not included.
  • Round bowl is generally less comfortable for men.

American Standard Colony Elongated Toilet

Best Budget American Standard Toilet

The Colony series is the entry-level line, but it doesn’t feel “cheap.” This is the perfect choice for a rental property, a basement bathroom, or a flip house where you need reliability without blowing the budget.

It features a “Tall Height” rim for accessibility and an elongated bowl for comfort. It uses a standard 2-inch flush valve and trapway. While it lacks the tornado-like power of the Champion 4, it flushes consistently and meets WaterSense criteria at 1.28 GPF.

Because it is a two-piece unit, it is lighter and easier to move into position if you are working alone. Just remember to check if the seat is included in your specific package, as some retailers sell the bowl and tank separately from the seat.

Pros

  • Excellent price point.
  • Comfort height and elongated bowl.
  • WaterSense certified.
  • Easy to find replacement parts.

Cons

  • Two-piece installation takes longer.
  • Basic aesthetic lacks modern flair.

How Long Do American Standard Toilets Last?

The porcelain itself can last a lifetime (50+ years) as long as it doesn’t crack from impact. The internal components, like the flush valve, fill valve, and flapper, are wear items. You should expect to replace the rubber flapper every 3 to 5 years and the fill valve every 7 to 10 years.

FAQs

Where is the model number on an American Standard toilet?

You can usually find the model number printed on the inside back wall of the water tank. Carefully lift the porcelain lid and look for a four-digit number starting with a “2” or “4” stamped near the water level line.

What is the warranty on American Standard toilets?

The warranty varies significantly by model. The budget-friendly Colony line typically carries a 2-year warranty, while the premium Champion 4 line offers an industry-leading 10-year warranty. Always check the specific documentation for your model.

Can I install an American Standard toilet myself?

Yes, most handy homeowners can install these toilets in about two hours. You will need a wrench, a putty knife (to remove the old wax ring), and a new wax ring or rubber seal. Two-piece models are lighter and easier for one person to handle than heavy one-piece units.
