Features Comparison: American Standard VS Kohler Toilets 2020

We’ve decided to compare the two brands and help you to come up with an informed choice.

  1. Flushing system

American Standard toilet has a very powerful dual flushing system that clears all the contents in the bowl in just one flush. But then, Kohler tends to use very little water during flushing. So, Kohler is very efficient in water usage while the American Standard provides a very powerful flush. The good thing with the American standard is that it clears all the waste in just one flush, while Kohler has been reported not to be very efficient in clearing waste at once. As a result, using the American standard toilet lets you save water in the long run.

For a silent flushing system, the American standard still tops Kohler. American standard toilets flush silently and not even your neighbor will hear a sound. This is not the case with Kohler as they produce a low sound, but it is not as loud as some other toilet brands on the market.

  1. Cleaning

I don’t have much to say about cleaning the American standard or the Kohler toilets as they are both very easy to clean. First of all, it all depends on the model and type of toilet. One-piece toilets are very easy to clean when compared to two-piece toilets. On top of that, Kohler toilets have an excellent finish which makes cleaning to be easy as they don’t stick. Alternatively, the powerful flushing system found in American standard clears all the waste and dust in the bowl leaving it sparkling clean after every use.

  1. Installation

Both of these toilet brands offer easy to install toilet models. Since they are made in the USA, they meet all the plumbing requirements and can be installed with much ease. The bolts are not tricky, and you just need to follow the installation instructions. One-piece toilets are easier to install than two-piece toilets. Take measurements of your bathroom before buying a toilet. You don’t want a large toilet taking out most of the space. Rounded toilets normally take up more space than elongated toilets.

  1. Maintenance

This is one area where Kohler faces some challenges. Many Kohler users have had different issues with their toilets such as clogging. On the other hand, American Standard users highly recommend their toilets and most of them haven’t had any challenges like leakages or clogging. So, American standard toilets are very easy to maintain when compared to Kohler toilets.

  1. Price

The American standard toilet brand offers some of the cheapest but quality toilets on the market. When compared to Kohler, American standard toilets are cheaper but still very effective in performance. So, it is just a matter of preference, but they differ in price slightly. American standard toilets are very durable and are offered at a lower price when compared to Kohler. But if you want a slightly comfortable toilet at a higher price, then you can choose one from Kohler.

  1. Design

Depending on your needs, you can go for the Kohler or American standard toilet. Kohler is known to have an elongated bowl and a comfortable height. While American standard offers different toilet designs with both round and elongated toilets being offered. American standard is also comfortable, but it needs more installation space. Kohler is great for compact areas and where the bathroom space is small. Also, Kohler toilets are more comfortable when compared to American standard toilets. Therefore, if you are looking for an elegant toilet to add to your modern bathroom, I would suggest you select Kohler.

American standard or Kohler? Which is a better toilet?

So, what is the conclusion of American standard vs Kohler toilets post? The Kohler and American standard toilet brands are efficient, powerful, durable, and very easy to clean. The final decision will depend on their price, efficiency in flushing, and comfort. American standard toilet is slightly cheaper and comes with a very efficient and silent flushing system. While Kohler is very comfortable and uses very little water per flush. When you compare these two toilet brands, it is evident that the American standard is a better toilet due to its ease of use and efficiency in performance. But Kohler is not far off as it has similar features and brings comfort to your bathroom.

All-in-all, you should pick a toilet that meets your demands and budget. After all, they are all durable and high-quality toilets. I hope this Kohler vs American standard toilets article was helpful. Still, have a question? Comment below.


  • Very helpful. I have a Kohler in two of my 3 bathrooms. We are getting ready to upgrade and renovate our ensuite bathroom and the plans from the contractor are calling for American Standard. I think you blew away some of my prejudices. Pricier is not always best.

  • I had my mind set on the Kohler aqua piston technology until I began to read it doesn’t take any waste that has splattered to the sides down in on flush. Did some other reading and then I found your article which sealed the deal for an American Standard or not the piston technology. I need to measure the space available and then I’ll make my decision. Thanks

  • I still need clarification: Is the Kohler AquaPiston assembly “Pressure-Assisted” vs. Gravity-Feed” ? I understood the pressure-assisted types to be significantly noisier.

  • I have installed 5 Kohler toilets in the last 5 years 4 in my house and one at daughters house … all of them are made in USA and have been flawless.
    Very powerful flush with no assist mechanism … not one clog or problem. The 3” flush valve works great .. very simple design.
    I would have no problem buying Kohler.

    • I am not saying Kohler is a bad toilet brand. Lots of people(like you) have a good experience with them. But, If I compare with American Standard, then Kohler isn’t a clear winner here.

  • If you are considering cost of maintenance in the long run and the fact that if you buy a Kohler your supporting a American company … Kohler is a clear winner. Kohler is a American company based in the US. Because of unfair trade … American Standard is now a Japanese company.

    • just bought Kohler Highline Curve, I believe they are made in China. Most of them now are made in China. No problem so far

  • Replaced 4 toilets because originals installed in home had a ceramic flaw (other brand), so dangerous to keep in place.

    Replaced two with Kohler and two with American Standard.
    The American Standard ones have had nothing but problems from the outset…ghost flushing etc. That kept happening even after supposed fix.

    Just over a year after being installed by a well qualified pumber, the ceramic tank on one of the American Standard toilets cracked with no warning. This was not a toilet that had excessive usage and wasn’t subject to damage…so can’t blame that.

    I will personally never buy American Standard again. That should not happen to ceramic..especially when not used excessively.

    In contrast, the two Kohler toilets have not had any issues to date.

    Given the damage that can he caused by water damage, all manufacturers should have higher standards for their production/parts. Faults like this should not be happening!

  • in my opinion NO ONE should buy the American Standard VorMax model toilet. Any toilet mfg. that sells a toilet that needs “instructions” on how to flush has lost touch with the consumer. To prevent the toilet from getting out of “prime” you need to flush it this certain way, and if you don’t it may take up to 5 flushes to get back in “prime”. Their own manual requires you to flush the toilet 5 times before use. The sad thing is I have 3 of the VorMax toileets in my home, and I flushed it 5 times to “prime” each one and thought I was done, that ain’t so I’m afraid

  • I have two complaints with the American Standard, the lid does not fit in one place, it slides all over the place. My old toilet lid did not move, it had a definite grove to set in. The flushing arm comes out of the handle and the wire pin keeps falling out of the chain pin.

    • Are you certain it is a dark line and not a shadow caused by the bowl shape and lighting in your bathroom?
      If it is, in fact, a dark line please try the following cleaning procedure:

      Please use CLR along with a blue non-scratch pad(the all blue pad you would use to wash your dishes).
      It should say non-scratch right on the packaging.
      You will add the CLR to the bowl and let it soak for 15 to 20 mins then use the blue pad to scrub away the build-up.

  • Hi Robert,

    I’m trying to decide between the below 3 toilets:
    Kohler Cimarron
    American Standard Cadet
    American Standard Vormax

    What I’m looking for is something that is easy to clean and cleans in one flush.

    Any suggestions on which would be better?

  • American Standard Vormax is a way better flush than a Kohler gravity flush toilet in my opinion. I have been a professional plumber for 37 years. I install on average 60 toilets a month and most of the toilets I need to unclog are the Kohler toilets. If someone was to pay me money to have a Kohler toilet in my house I would rather buy a American Standard Vormax toilet. Plus all Vormax toilets come with a 10 year warranty on parts no one else can match that. I see almost no return calls ever on Vormax toilets. To say Kohler is a better toilet is wrong and almost a joke.

  • A few questions:
    1. Do the American Standard and Kohler ceramics have scrathable surfaces that — over time — darken and look like there are “solids” still in the tank, especially in the bottom exit area? If so, does this apply to all models in both brands?

    2. Do both brands have water outlets along the rim to help flush anything that is affixed to the side of the bowl? A plumber just installed an American Standard Cadet Pro in the house, and I cannot flush the toilet any amount of times to get even a piece of grass of the side of the bowl without having to get the toilet brush out and clean it manually.

  • I had the exact same three American Standard Toilets installed in my home from Lowe’s; one in June 2019 and two installed in May 2020.
    $199.00 each American Standard Model 2514101S.020, Two piece Elongated Standard Toilet. 345 Reviews 5 Stars. I am grateful and I am VERY satisfied. Thank you for your well written article!

  • I am posting this piece on Sunday, June 28,2020. It’s my understanding that the American Standard 2862056.020 Fairfield 1 Piece Toilet in White is nolonger in production and that, its been discontinued. The company customer rep even confirm this to me via facebook chat. I am concerned, this model is still in stock both on amazon and Home Depot stores. May someone here help to know as to why this model was discontinued? Will I get unknown issues later if I but this model? To my knowledge, this is the only model in line up with the lowest height from floor to the bowl.

  • I just installed two American Standard Vormax toilets in my house. They were pricey, but the flush is great and the bowl stays clean. The design of the toilet is different from the regular gravity toilet. It’s actually real innovation compared to just a bigger flush valve in the tank and a “piston” which it’s just a plastic cylinder. The Vormax has two flush valves separating both the siphon and bowl rinse and reverses the water usage ratios between the two. There is a This Old House clip of how it works on YouTube.

    These two Vormaxs are replacing two pressure assist Kohler toilets I bought about five years ago, they both came with quality control problems and have been a hassle to maintain.

  • My son is 6’2 and growing is it better to buy a high toilet and if so what the best one? I see Kohler is ok then it says American trending is better. Please help. My son is uncomfortable in our low toilet. He’ll i am sometimes and I’m 5’5. Lol ty

  • After 2 houses with Kohler I would never buy anything else, beyond look, choices, performance, the Customer Support and Warranty Support is off the charts great. Our current house was gutted and rebuilt with all Kohler. After 13 years I still have to contact them given we have so many BAs, 2 kitchen sinks/faucets, a “car wash” shower, Kohler sink basins and tubs. EVERYTHING plumbing is Kohler. They STILL send replacement parts for FREE. Free parts, free shipping, all fully covered lifetime and the customer support is as knowledgeable as any technical service I’ve ever spoken with. The plumbing company that did the install loved their products. My current plumber loves them and talks about how other brands make customers send pictures and original invoices for support. All I do, on the occasion I have to every few years, is say what I have. Nothing against American Standard in any way, buy mileage significantly varies on those items. I’ve built homes, remodeled them, and bought numerous new construction, culminating with buying the worst house on the block and gutting it to the studs, adding to it, repiping, reconductering, everything, and I have never once regretted my decision to go all in on Kohler, including towel holders, etc. Everything is Kohler. My dad was so impressed with our Kohler Memoirs Comfort Height Elongated Class 5 flush toilet, he bought one. That, from a guy, who is a remodel-phobe. Hope that helps.
