The Best Bidets for an American Standard Toilet 2023

Best Bidet for an American Standard Toilet

Today, we’re looking at the best bidets for American Standard toilets. Some toilets are more or less suited to certain bidets, and it’s best not to have to learn the hard way–the last thing you want is to go through an install only to have to send the bidet back. 

The best bidet for an American Standard toilet is the Brondell S300. It’s one of the best entry-level seats on the market and happens to be one of two Brondell bidets confirmed to fit most American Standard toilets. Other great options include the Bio Bidet Slim Edge and 270 Duo bidet attachments.

In writing this article, I poured through bidet fitment data available online from various bidet manufacturers.  

Best Electric Bidet Seats for an American Standard Toilet 

The bidets mentioned here fit most American Standard toilets, but a few of their toilets (probably <1%) have odd shapes and dimensions that can cause bidet installation problems.

Specifically, these toilets are not compatible with the Brondell bidets listed.

  • Champion 4 Normal Height Elongated Complete 1.6 GPF Toilet 
  • Champion 4 Round Front Complete 1.6 GPF Toilet 
  • Champion 4 Right Height Round Front Complete Toilet 
  • Champion 4 Tall Height Elongated Complete Toilet 
  • Fairfield Elongated One-piece Toilet
  • Mainstream Waterwarden Right Height Elongated Complete (elongated) Toilet
  • Portsmouth Champion 4 Right Height Elongated 1.6 GPF Toilet 
  • Portsmouth Champion 4 Right Height Round Front 1.6 GPF Toilet 

If you have any of the above toilets, you’ll want to go with the American Standard Spalet or one of the bidet attachments in the next section. 

The Best Overall: The Brondell Swash 300 

Brondell Inc. S300-RW Swash 300 Round Advanced Bidet Toilet Seat, White

The Swash 300 is one of my go-to recommendations for a good entry-level electric bidet seat. You can check out the latest prices here. It offers the most important features common to electric seats (warm water, self-cleaning nozzles) minus the air dryer which cuts the price almost in half.  

Pros of the Brondell Swash 300 

Guaranteed Fit with most American Standard Toilets 

Brondell lists the Swash 300 as one of two electric bidets (along with the Swash 1000) that are compatible with all but the most obscure American Standard toilets (source). 

Fits Round and Elongated Bowls 

Compatibility with round vs. elongated toilets is probably the most important feature when it comes to choosing a bidet seat (electric and non-electric). 

Elongated toilets are about an extra two inches longer. It may not seem like much, but the extra couple of inches make all the difference in the world when it comes to bidet fitment. Get the wrong kind you’ll be boxing the bidet up and sending it back. 

Unfortunately, toilets with round bowls are often neglected by bidet manufacturers. But Brondell is pretty good about making their seats available for both bowl designs.  

Installation-Friendly (Remote Control Instead of Side Panel) 

A lot of electric bidets have side panels that look like the kind found on bidet attachments. Remote controls are better because they don’t interfere with installation. This is important because American Standard makes a lot of fancy toilets with odd dimensions that can interfere with bidet installation. 

It’s not usually a deal-breaker, but some toilets don’t take to bidets that have side panels. When it happens, it’s often the fault of the side panel design—either it’s too bulky or it extends below the seat level—getting in the way of the back of the toilet rim during installation. 

But bidets with remote controls take the issue out of the equation altogether and present the fewest installation problems.  

Retractable Self-Cleaning Nozzles 

The cleaning wands are out of the way when you’re doing your business, so they’re less likely to get soiled with use. The nozzles are self-cleaning, rinsing themselves with each use. Hence, they’re automatically cleaned in case they do get dirty. 

Precision Aiming, Front and Rear Wash 

The Swash 300 allows the user to clean the front and rear regions. Being able to control the nozzle position makes aiming the bidet more accurate.

Precision Water Temp and Pressure Adjustment 

Unlike non-electric bidets, electric seats like the Swash 300 allow the user to adjust the water temperature and pressure.  

Precision control of the wand and water pressure makes for higher comfort and more accurate aiming. 


Cutting out the air dryer lowers the price big time without compromising the clean. The main reason most make the switch to a bidet is to get a clean that’s 10x better than what toilet paper offers. You don’t need a dryer, and some users find that they don’t work that well anyway. 

Heated Seats 

I didn’t really think I’d use this function, but I do, especially in the winter months. It’s more comfortable and really relaxes the pelvic muscles which a lot of people claim helps with constipation.

Cons of the Brondell Swash 300 

  • No warm air dryer. Air dryers are a pretty standard feature on electric bidets these days, but entry-level seats often lack this function. The main benefit of having a dryer is that you’re able to further reduce, or even eliminate, toilet paper use. Keeping TP use to a minimum is good for the environment and helps the user save a lot more money in the long term. But most users of electric bidets continue to use TP, whether their bidet has a dryer or not. Also, some find dryers to be ineffective at finishing the job and others don’t like having to sit there long enough.
  • Limited warm water flow. The Brondell Swash 300 has a tank-type water heater that puts out a limited stream of warm water. The warm temp lasts for about a minute before running cool, which is usually plenty of time. But, if you plan to use the front wash mode a lot, or will be sharing the bidet with multiple users, then you may want to go with the next model. 

Best Luxury Seat: The Brondell Swash 1000 

Brondell S1000-EW Swash 1000 Advanced Bidet Elongated Toilet Seat, White

If you’re looking for an advanced bidet seat that’s compatible with American Standard toilets, I recommend the Swash 1000 (alternative price check on Amazon.

Not all bidets in this article are Brondell. It’s just that Brondell happens to be one of the best brands out there (up there with TOTO) and they confirm which of their bidet models are compatible with American Standard Toilets.  

I often recommend seats in the Swash lineup anyway, so it worked out well that the 300 and 1000 are AS toilet-compatible. 

As you’d imagine, the Swash 1000 has more features than the 300 and costs a bit more. I wanted to recommend it because some will find the extra features to be worth the additional cost.

That’s not always the case, as some bidets have tons of bells and whistles that do little else but drive up the price.  

Pros of the Brondell Swash 1000 

Guaranteed Fit with Most American Standard Toilets 

Like with the 300, Brondell lists the Swash 1000 as compatible with most American Standard toilets (source). 

Fits American Standard Toilets w/Round and Elongated Bowls 

This one also fits both elongated and round toilet bowl designs.  

Higher Compatibility with Fancy American Standard Toilet Designs 

Like with the 300, the Swash 1000 has a remote control (no side panel). 

Having a remote, the bidet is more likely to be compatible with ultra-modern toilets with unconventional dimensions (one-piece toilets, low-profile tanks, French curves, etc.). 

Endless Warm Water 

All electric bidets provide heated water, but only fancier seats offer endless warm water, so this is probably the most impressive feature mentioned in this article. As mentioned, entry-level seats have a small tank that stays hot 24/7 so warm water will be available at a moment’s notice.  

The small tank provides about a minute of warm water before it empties, at which point it has to heat another batch of water before it can be used again, which takes a while.  

The Swash 1000 has an instantaneous water heater that heats water on the spot as needed. 

Lower Electrical Costs 

Keeping electrical costs low helps the user net even more savings with bidet use over the long-term. 

The tank-type heaters on less expensive bidets need to be powered around the clock to keep the water warm and ready for when needed.  

Not relying on keeping a reservoir heated, this model only draws power for water heating when the bidet is in use. 

Lower-Profile, More Aesthetic Design 

What’s considered aesthetic is a matter of opinion, but most agree that lower-profile bidets are more visually appealing.  

That’s not to say that a bidet needs to be unnoticeable for the bathroom to look good, but most prefer a sleeker less-bulky design. 

Not having a heated tank in the back of the seat, the Swash 1000 is far less bulky than most electric seats and doesn’t slope as much from back to front compared to bidets with tank-type heaters.

Also, by not sloping much from back to front, most find the sitting experience to be more comfortable, because the user isn’t forced to the front of the seat.   

Precision Spray Adjustment (Water Pressure and Spray Width) 

Luxury bidets like the Swash 1000 allow way more control of the water flow compared to entry-level seats. Electric bidets always beat out non-electric seats and attachments in this respect, but not all electric seats are created equal in letting the user control the water flow. 

With this model, several settings allow the user to control the wand position, spray width, and pressure to get a customized wash. 

For example, a stronger narrower stream is great for thorough cleaning (for messy bowel movements) and some find it useful for DIY “enemas”.

Softer water pressure and wider spray widths provide a soothing cleanse. Also, wider spray patterns are great for older adults and those with limited mobility because less body positioning is needed to get water to the right place.  

Other Great Features Unique to Electric Bidets 
  • Precision aiming, front and rear wash capabilities. Electric seats like the Swash 1000 are more accurate because the user has more control over wand positioning.  Front wash mode is great for female hygiene and for general frontal cleansing.  
  • Heated seats. Again, not needed, but super comfortable. 

Cons of the Brondell Swash 1000 

The main drawback of this model is the cost. Prices vary, but it’ll usually run you about twice the cost of the Swash 300. 

But the amount you’ll save on toilet paper (by having an air dryer) will quickly make up for the price difference. It may not eliminate manual drying altogether, but It’ll help you cut way down on TP use. Then there are the savings in electrical costs from not using a tank-type water heater. 

But to be clear, none of the extra features in the Swash 1000 are necessary.  

Best American Standard Pick: The AC 1.0 Spalet Elongated Bidet Seat

American Standard 8013A80GPC-020 Advanced Clean AC 1.0 Spa let Bidet Seat With Side Panel Operation

One safe bet is to go with a bidet put out by the same company. For that, I’d go with their entry-level electric bidet called the Advanced Clean 1.0 Spalet. Most who are aware of bidets know that American Standard still makes European-style standalone units.  

But fewer seem to know that the brand has entered the modern bidet market with both electric seats and non-electric bidets. 

This one is not suitable for round toilet bowls. If your bowl is round, I’d go with one of the above two. 


  • High compatibility with AS toilets.  Being manufactured by American Standard, this model should fit a wide range of AS toilets. AS doesn’t have much bidet/toilet fitment data online, so if you have a really obscure toilet design (French curves as with the Fairfield), you may want to reach out to them directly to ensure compatibility with your toilet. 
  • Price. American Standard puts out several electric bidet seats, and this model is the most affordable. I’ve compared them side-by-side and the basic Spalet has most of the features offered by the other models but at a much cheaper price. 
  • Heated seats. Three presets (factory temp settings) and two custom levels. 
  • Five spray patterns. Again, having several spray patterns to choose from is useful for several reasons. It ensures there’s something suited to different preferences (for comfort, etc.) and some spray modes are useful for specific situations (e.g., limited mobility, strong vs soft cleanse). 
  • Five water pressure settings. Like with spray patterns, it’s nice to have several pressure settings to choose from for different applications and to find the right comfort level. 


  • No warm air dryer. Like the Swash 300, this one lacks an air dryer.  
  • Side panel (potential installation problems). In theory, it’s more likely you’ll run into installation issues on AS toilets with odd dimensions. However, the side panel doesn’t seem to extend below the bidet which means an extra-wide space at the back of the toilet shouldn’t be an issue. 
  • Limited warm water. Also, like the Brondell Swash 300, this model provides a limited flow of warm water. 

Best Attachments for an American Standard Toilet 

In case you’re new to the subject, bidet attachments are fixed to your current toilet but don’t replace any parts.

Bio Bidet makes high-quality bidet attachments and is one of the only brands that specify which models are incompatible with American Standard toilets. 

The following American Standard toilets are compatible with Bio Bidet attachments (source): 

  • Antiquity, Astute  
  • Cadet1-4, Clean, Colony 
  • Dual 
  • Edgemere 
  • Mainstream 
  • Portsmouth 
  • Reliant, Repertoire, Retrospect  
  • Saver, Studio 
  • Titan, Tropic 
  • Vormax  
  • Yorkville 

These toilets are incompatible

  • Fairfield 
  • Tofino 

These toilets might be incompatible with the warm water attachment:

  • Town Square
  • Boulevard

If your toilet isn’t listed here, then it should be good to go.

Cold Water Option: The Bio Bidet SlimEdge Bidet Attachment 

Bio Bidet SlimEdge Simple Bidet Toilet Attachment in White with Dual Nozzle, Fresh Water Spray, Non Electric, Easy to Install, Brass Inlet and Internal Valve

Bio Bidet has some great non-electric bidets, of which I’d recommend the Slim Edge bidet attachment as it is the most compatible with American Standard toilets.

Bio Bidet SlimEdge Simple Bidet Toilet Attachment in White with Dual Nozzle, Fresh Water Spray, Non Electric, Easy to Install, Brass Inlet and Internal Valve 

Bidet attachments offer fewer features, but they get the job done and still provide a hygienic experience far superior to what you get with toilet paper.  


  • Highest compatibility with American Standard Toilets. The only two American Standard toilets that don’t fit the SlimEdge are the Fairfield and the Tofino. The Slim Edge should fit about any other AS toilet, even those with low-profile tanks and French curves.
  • Least expensive option. Price-wise, the SlimEdge is about middle-of-the-road for bidet attachments. Attachments, as a category, are much cheaper than electric bidets. 
  • Dual nozzles. You don’t get the control offered by electric bidets, but the Slim Edge does have dual nozzles for front and rear cleansing, a feature sometimes missing with bidet attachments. 
  • Easy installation. Most bidets are easy to install, but non-electric units can be up and running in as little as 10-15 minutes, compared to the hour often needed to install electric seats. 


  • No self-cleaning nozzles. Most bidet attachments have self-cleaning nozzles these days, so this was surprising. If you go with this model, I’d manually clean the nozzles more often. 
  • No warm water. This is the only bidet mentioned that doesn’t offer warm water. It’s more of a comfort issue, as warm water isn’t needed to get a great clean. 
  • Few features compared to the electric options. This always applies, but I wanted to mention it for those who are new to the subject.  

Best Warm Attachment: The Bio Bidet 270 Duo 

Bio Bidet BB-270 Duo Dual Nozzle Hot & Cold Fresh Water Spray Non-Electric Bidet Toilet Seat Attachment, Posterior & Feminine Wash, Certified Check Valve, Brass Inlet, DIY Easy Install

The BB 270 Duo is a step up from the SlimEdge in several ways, but the main benefit is that it offers warm water. You can check out the current prices here and here.


  • High compatibility with American Standard Toilets. You’ll be able to install the 270 on most American Standard toilets. See the cons for exceptions. 
  • Warm water. As mentioned, the main difference with this model is that it provides warm water. There is a catch: you’ll need to be able to access the hot water shutoff valve underneath the bathroom sink for the warm water to work. See below for more detail. 
  • Self-cleaning wands. Unlike the SlimEdge, the BB 270 Duo has self-cleaning wands, providing a more sanitary experience. 
  • Inexpensive option. The Duo is a bit more than the SlimEdge because it’s a nicer model overall, but it still costs much less than electric seats. 
  • Dual nozzles. The BB 270 Duo is great for front and rear cleansing. 


  • Potentially incompatible with certain one-piece toilets. As for American Standard toilets, the Boulevard and the Town Square are one-piece. Sure enough, Bio Bidet does mention that some of their attachments, including the 270 Duo, might pose installation issues with the two toilets. Apparently, the side panel position gets in the way of the back of the toilet rim (where the bowl meets the tank), an area that’s often extra-wide on one-piece toilets. You can always send it back if it doesn’t fit, but it may be less hassle to go with another model. 
  • You’ll need a compatible bathroom setup. With non-electric warm water bidets, you have to consider the bathroom as much as the toilet. First, the toilet and sink need to be on the same wall. A 90-degree angle might work, but opposite walls are out of the question because the warm water hose would have to remain draped across the floor. Secondly, the toilet and sink will need to be close enough (no more than ~8-9 feet apart) for the warm water hose to reach. Finally, any cabinetry around the sink (for those who have a vanity) will have to be drilled into, which some renters may not be willing to do.  
  • Other issues. Getting warm water from a non-electric bidet has its benefits and drawbacks. The warm water supply is endless, but it can take a minute or two to heat up (because it’s sourced from the same plumbing as the bathroom sink) and some users find they’re done cleaning by the time the water starts to kick in. 
  • Few features compared to the electric options.
