Kohler vs American Standard Toilets – In-Depth Comparison & Top Picks

With more than 100 years of experience in the toilet industry, Kohler and American Standard toilets have been known to provide the best flushing technologies, superior durability, and advanced features.

Kohler & American Standard

The real question is, though, which brand is best? Some people swear by American Standard toilets because of their increased efficiency, while some prefer Kohler toilets for the added comfort.

We’re here to answer that question with a thorough comparative review of Kohler vs American standard Toilets to help you choose the toilet brand that works best for you!

Let’s first dig into both companies and look at whether their toilets are made in the USA or not.

Kohler toilets are made in three U.S. plants in Kohler, Wisconsin; Brownsville, Texas; and Spartanburg, South Carolina, and one big plant in Monterrey, Mexico. American Standard toilets are made in Piscataway, New Jersey, which also houses the company headquarters.

Kohler and American Standard Toilets Features Comparison

Below we have an in-depth guide about each brand that will help you choose between Kohler or American Standard.

Material and Durability

When it comes to durability and maintenance, Kohler toilets are a bit difficult to maintain. Consumers have noted that Kohler toilets tend to clog and leak a lot, which causes a lot of inconvenience throughout the years.

Kohler toilets are manufactured with materials like china, vitreous china, porcelain, and ceramic. Vitreous china is very sturdy and durable as it is coated ceramic, which lasts years without causing damages.

American Standard is very popular due to its highly efficient toilets that don’t clog or leak, lessening the need for a plunger. American Standard uses vitreous china and porcelain to construct their toilets, making these toilets easy to clean.

Both of these brands are American companies, which makes ordering spare parts very easy.

Clearly, American Standard proves to be the better toilet brand in the durability department.

Flushing System

Flushing power should always be the main focus when you’re looking for a new toilet. It can not only allow you to save on your water bill, but it also ensures that all the waste contents in the toilet bowl are rinsed off with a single flush.

While American Standard offers advanced VorMax flushing technology, Kohler provides water efficiency with its Class Five and Ingenium flushing systems, saving up to 16,500 gallons of water every year (if the flush is 1.28 GPF).

Let’s take the Kohler Highline and American Standard Champion 4 into consideration. 

We’ve found that the Highline is unable to flush away solid waste without causing clogs or flushing twice.

On the other hand, the Champion 4 rinses off the waste with one powerful flush because it has a 4-inch tank flapper rather than the standard 3-inch.

In this department, American Standard wins because of its highly efficient flushing mechanisms, even though they make a little noise.


Both toilets are very easy to clean and maintain. Kohler utilizes an outstanding surface finish, while American Standard offers the EverClean finish along with a powerful flush that leaves the toilet bowl very clean after every flush. 

Remember that Kohler asks you to use soft abrasive cleaners to clean the toilet instead of strong abrasives to ensure that the vitreous china doesn’t get damaged.

However, it all comes down to the choice of toilet design. One-piece toilets are much easier to clean than two-piece toilets because the lack of gaps between the tank and bowl prevents dirt particles from sticking to the corners.

Toilet and Bowl Types 

Both American Standard and Kohler provide a wide variety of toilet type selections in the marketplace along with different types of toilet bowl designs.

Kohler offers one-piece toilets, two-piece toilets, urinals, and wall-hung toilets with round-fronted or elongated bowl designs. Elongated bowl designs are very comfortable since they evenly distribute the weight on the bowl.

American Standard provides a selection of one-piece toilets, two-piece toilets, wall-hung toilets, floor-mounted toilets, and WC close-coupled toilets equipped with elongated or round-fronted bowl designs.

Design and Colors 

Whether to go for a Kohler or American Standard toilet all depends on you and your design needs.

Kohler toilets are extremely popular for their sleek, computerized design that often comes with an elongated bowl and Right Height feature. These features make Kohler toilets very comfortable to operate and accessible to everyone in the house. 

Kohler toilets are also ADA-certified when the height is more than or equal to 16 ½ inches while still being compact. They are very suitable for en-suites, powder rooms, and bathrooms with limited space.

American Standard focuses its functionality more on efficiency than design. So, if you want to buy a toilet that looks amazing, we’d always suggest a Kohler toilet.

American Standard offers color selections that include linen, white, and bone, while Kohler offers white, biscuit, dune, black, and almond.

Price Difference 

American Standard produces the most affordably-priced, quality toilets on the market. They are slightly less expensive than Kohler toilets while providing high-performance, easy maintenance, and superior features.

Clearly, American Standard provides much more efficient products with the added advantage of an affordable price.


American Standard and Kohler exceed industry standards due to their exceptional performance. These companies are affiliated with a lot of certifications.

American Standard toilet is certified with CEC, EPA WaterSense, CalGreen, and ADA (Americans with Disabilities Act)

Kohler is also affiliated with all the above certifications along with Declare and Universal Height.

These certifications ensure that the toilets are water efficient and are being manufactured without polluting the environment.


American Standard provides a warranty of 5 to 10 years with every purchase. On the other hand, Kohler provides a 1-year limited warranty.

Advanced Features
