American Standard Toilets: Features to Compare

Flush technologies

American Standard offers several flush systems, with VorMax being one of the most often discussed. VorMax is a type of flush that combines a siphonic action with a directed rim wash. The idea is to push waste through the trapway while also scrubbing the bowl surface during the flush. This is not a pressure-assisted system; it uses the water stored in the tank and the shape of the bowl to create a strong pull. You will see VorMax on both one-piece and two-piece models, and it is often paired with a chair height bowl for accessibility.

Another system you might encounter is the Champion 4, which uses a wider flush valve (typically 4 inches) to move water quickly. While we cannot verify specific performance numbers, the wider valve allows a larger volume of water to enter the bowl in a short time. Both VorMax and Champion 4 are single-flush designs. If you prefer a dual-flush option, American Standard also makes dual-flush models that let you select a reduced water volume for liquid waste, which can help save water. The EPA notes that dual-flush toilets can save even more water when the reduced mode is used, but the exact savings depend on your usage.

When comparing flush systems, consider how the toilet handles solid and liquid waste, how noisy it is, and how easy it is to maintain. A gravity-fed flush is the most common and uses the natural weight of water. Pressure-assisted systems use air to boost flushing power but are typically louder and need a different tank design. American Standard largely uses gravity-fed siphonic flushing, which is quiet and reliable for residential use.

EverClean surface and glaze

The EverClean surface is a protective glaze applied to the toilet's interior and exterior. It is designed to inhibit the growth of bacteria, mold, and mildew, which can cause stains and odors. This is not a replacement for regular cleaning, but it can make the surface easier to wipe and reduce how often you need to scrub. The glaze is applied during manufacturing and is permanent for the life of the fixture, though harsh cleaners can degrade any glaze, so it is best to use non-abrasive products.

When comparing American Standard models, check whether the toilet has a fully glazed trapway. A glazed trapway reduces friction inside the drain channel, which helps waste pass through more easily and lowers the chance of clogs. EverClean is often applied to the trapway as well, though some budget models might skip that step. To verify, look at the spec sheet or ask the manufacturer. A fully glazed trapway is a good indicator of build quality.

Also consider the rim design. Some American Standard toilets have a skirted design that hides the trapway and creates a smooth exterior, making cleaning easier. Others have a traditional exposed trapway, which can accumulate dust but is easier to access for repairs. Choose based on your cleaning priorities and the style of your bathroom.

Comfort height and ADA compliance

Many American Standard toilets are marketed as comfort height, which means the seat height is higher than a standard toilet. The ADA Standards for Accessible Design specify that the height of a toilet seat must be between 17 and 19 inches from the floor to the top of the seat for public accommodations. American Standard comfort height models typically fall within that range, making them easier to sit down on and stand up from, especially for taller individuals or people with mobility challenges.

If you are remodeling for accessibility or planning for aging in place, consider an American Standard toilet that is labeled ADA compliant. The label means the toilet meets the 2010 ADA Standards, which also include requirements for the location of the flush handle and clearance in front of the toilet. For a home bathroom, you may not need full ADA compliance, but a chair height toilet offers similar benefits. Measure your existing toilet or floor area to ensure the height works for everyone in the household.

Note that the ADA height measurement is taken with the seat installed. If you plan to use a thicker seat or a bidet seat, the total height will change. Always check the nominal height listed by the manufacturer and add the thickness of your chosen seat. For mixed-height families, a standard height toilet (around 15 inches) may be more comfortable for shorter users, while comfort height suits most adults.

Rough-in and installation

The rough-in distance is the measurement from the finished wall to the center of the floor flange. American Standard toilets come in common rough-ins of 10, 12, and 14 inches, with 12 inches being the most typical in American homes. Before buying, measure your rough-in carefully. If you are replacing an old toilet, the existing rough-in size determines which model you can install without moving the waste pipe.

American Standard also offers toilet styles that work with different floor types. Most are floor-mounted, but there are also wall-hung models that hide the tank in the wall, though these are less common in the US. For a wall-hung toilet, you need a manufacturer's in-wall carrier system, and the installation is more involved. If you are not sure about your rough-in, see our guide on how to measure rough-in or consider a 12-inch rough-in model, which covers the majority of installations.

When installing, pay attention to the toilet's weight, especially for one-piece models that are heavier. A heavier toilet may require two people to lift and place. Also check the toilet bolt spacing and the distance between the tank and wall to ensure a comfortable fit. American Standard typically uses standard 7-inch spacing, but always confirm with the spec sheet.

Water efficiency and WaterSense

The EPA's WaterSense program certifies toilets that use no more than 1.28 gallons per flush (gpf) and meet strict performance criteria. Many American Standard models carry the WaterSense label, meaning they are at least 20 percent more efficient than the federal standard of 1.6 gpf. By choosing a WaterSense labeled toilet, you are helping conserve water without sacrificing flushing power.

When comparing American Standard models, look for the WaterSense logo. It indicates the toilet has been independently certified to clear waste, clean the bowl, and transport waste down the drainline. The EPA's residential toilets page explains that WaterSense labeled toilets perform as well as or better than standard 1.6 gpf models. If you want the most water-efficient option, look for a dual-flush model, which uses a reduced flush for liquid waste, though the actual water savings depend on how you use it.

You might also see models that use more than 1.6 gpf for certain applications, such as pressure-assisted toilets, but these are rare for home use. For typical residential use, a 1.28 gpf single-flush or dual-flush toilet is a safe and effective choice. Check the best 1.28 gpf toilets guide for comparisons.

Bowl shape and cleaning

American Standard offers both round and elongated bowls. Elongated bowls provide more seating area and are generally preferred for comfort, but they require more clearance in front. Round bowls are more compact and fit better in tight bathrooms. Consider the dimensions of your bathroom and the available space. The round vs elongated guide can help you decide.

Beyond shape, look at the bowl's interior design. Some American Standard toilets have a rimless design that makes cleaning easier because there is no rim to collect grime. Others use a standard rim with holes for water distribution. VorMax's directed rim wash is designed to clean the bowl surface during flushing, but it still requires periodic manual cleaning. The EverClean surface helps reduce staining, but no toilet is truly self-cleaning.

If you are interested in a toilet with a built-in bidet, American Standard has some models that include bidet functionality, though the selection is smaller than dedicated bidet brands. For add-on options, see our guide on bidet toilets vs bidet seats.

What to pick for your use

Questions

What is the VorMax flush system in American Standard toilets?

VorMax is a siphonic flush system that uses a directed rim wash to clean the bowl while flushing. It combines a strong pull with a thorough surface rinse designed to reduce the need for manual scrubbing. It is available on many American Standard models, typically paired with a chair height bowl.

Does the EverClean surface eliminate the need to clean the toilet?

No. EverClean is a protective glaze that helps inhibit the growth of mold, mildew, and bacteria on the surface, making it easier to clean and reducing stains. You still need to brush the bowl periodically, but the surface resists buildup better than standard glazes.

Are all American Standard toilets WaterSense certified?

Not all, but many are. WaterSense certification means the toilet uses no more than 1.28 gallons per flush and meets EPA performance criteria. Check the product's spec sheet for the WaterSense label. Some models may use more water for specific features, but those are rare in residential lines.

What is the difference between a 12-inch and 14-inch rough-in toilet?

The rough-in is the distance from the finished wall to the center of the floor drain flange. A 12-inch rough-in is the most common in American homes, while 14-inch is found in older or custom installations. You must match the rough-in to your existing drain unless you are moving the pipe.

Are American Standard toilets ADA compliant?

Many American Standard toilet models are labeled as ADA compliant, meaning they meet the height and clear floor space requirements from the 2010 ADA Standards. Typically, these are comfort height models with a seat height of 17 to 19 inches. Always verify with the manufacturer's specifications.

Which American Standard toilet is best for a small bathroom?

A round bowl model with a 12-inch rough-in and a compact one-piece design is a good choice for tight spaces. Measure your floor clearance and rough-in first. See our compact toilet guide for tips on maximizing space.
