Swash 100 EcoSeat Toilet Fit Information

Swash Ecoseat Toilet Fit Guide

The Swash Ecoseat S100 is designed to fit Elongated toilets only, however this model will fit select Round fixtures. Please reference the diagram above for size verification. The Ecoseat S100 will not fit French Curve fixtures.

Swash 100 Ecoseat Plumbing Requirements

The Swash is compatible with over 98% of residential fixtures in the United States. All that is required to hook your Swash up to water is a toilet fixture with a tank. Wall-mounted toilets require a separate water connection to be added in the bathroom in order to provide water for the Swash.

The Swash includes everything that you need to plumb it into the water supply of your current toilet fixture. In the rare case that your water supply line is inflexible you will have to purchase a flexible water line to complete the installation. A T-valve (shown) provides the Swash with a continuous flow of clean water to use for washing.

Brondell Swash Advanced Bidet Seat FAQs




What is a Swash?

A Swash is an advanced toilet seat that offers men, women, and children a fresh and hygienic cleansing using two retractable wash wands for posterior and feminine areas.


How does a Swash work?

The Swash replaces your existing toilet seat.  Two self-cleaning, retractable wands are used, one for the posterior wash and another for the feminine wash. All functions are easily operated at the turn of a dial.


What are the differences between the Swash models?

A model comparison chart detailing the differences between models can be found HERE.


Where is the Swash manufactured and serviced?

The Swash is manufactured in Korea. All of Brondell’s products are serviced in San Francisco, CA, USA.


What is your Return and Warranty policy?

Our Warranty policy can be found HERE, and our Returns policy can be found HERE.


When will I receive my order?

  • Orders typically ship the next business day
  • US orders ship from our warehouse in Effingham, IL and typically ship via UPS Ground unless otherwise specified
  • Delivery times vary, but usually are between 1-6 business days depending on distance from the warehouse
  • Brondell ships orders directly from our warehouse in Toronto, ON to destinations within Canada

Will the Swash bidet fit my toilet?

Toilet Fit information can be found HERE.  Please note this model only comes in the Elongated size. 


What installation is required?

Standard installation is quick and easy. It involves a few simple steps: shutting off the water valve at your toilet, removing your existing toilet seat, installing the Swash mounting bracket, and attaching the Swash to the bracket and connections. The included T-valve is installed directly below the toilet tank to direct filtered household water to the Swash. 


What are the plumbing requirements of the Swash?

Plumbing Requirements can be found on the "INSTALLATION" tab on each product page.


Do I need an electrical outlet?

No, the EcoSeat operates without electricity.  


What are the interior hole dimensions of the bidet seat?

The interior hole of the elongated-size Swash is 11.5”L x 8”W. 


Is your Swash compatible with seat elevators or toilet seat risers?

The Swash is compatible with some Carex brand risers, found HERE.


For the Swash 100, can the control arm be moved to the left side, and does this model come in the Round size?

No, the control arm cannot be adjusted. The Swash 100 EcoSeat only comes in one size, elongated. However, if you have a toilet with a length of at least 20.4” from the front of the tank to the front edge of the toilet bowl, the bidet should fit on your toilet. More information on EcoSeat Toilet Fit can be found HERE.


What colors are available for the Swash?

The Swash 100 is only available in white.  If you are looking to match your new Swash with an existing toilet, our color recommendations for American Standard, Kohler, and Toto toilets are as follows:


  • American Standard: White
  • Kohler: White
  • Toto: Between Colonial White and Cotton (not a perfect match)


back to top



How do you operate the Swash?

The Swash 100 is operated by simply turning a dial.


Can a Swash be used by children, elderly, and handicapped?

Absolutely! Children love using a Swash, and they are wonderful for parents with children who are potty-trained but not yet able to clean themselves. Those who are elderly, or who have limited mobility or other limitations, can especially benefit from using the Swash.


How long does the warm water last?

The Swash 100 pulls room temperature water from your existing water line and does not heat the water.  The wash can run as long as you prefer. 


What is the difference between the front and rear wash?

The front wash offers a feminine cleanse while the rear wash offers a posterior wash for both men and women.


Do the wands ever "get in the way"?

No, the wash wands are only extended during the cleaning cycle. At all other times they are housed inside the unit to avoid being contaminated. 


Is a Swash safe and reliable?

Brondell warrants its products for one year from the date of purchase. With proper usage, Brondell products will provide years of reliable use. Owners should read and follow all safety precautions in the literature provided with the product.


What is the weight limit of the Swash?

The Swash Lid has a weight limit of 270 pounds. The seat part has a weight limit of 330 pounds.

What maintenance is required?

Swash seats are made of germ-resistant plastic. They can be cleaned with a soft, wet cloth and a mild detergent.  Although Swash wands are self-cleaning, Brondell recommends they be cleaned with a soft brush monthly or as needed. Brondell recommends that the removable mesh filter is cleaned on a regular basis as needed.


What are bidet filters? How often should they be replaced?

The Swash EcoSeat 100 must be used with a filter.  The bidet comes included with a filter but if your home uses hard water, well water, or softened water, you may need to change your filter every six months.   Purchase information can be found HERE.

Is the Swash covered by Medicare or Medicaid?

You may be able to get coverage particularly with the state-level Medicaid, but you should check with your doctor and/or insurance provider for more information. If you have a medical condition that a hygienic bidet toilet seat can help, then your doctor may be able to prescribe a Swash bidet for you and you may be eligible to receive insurance coverage for it.

Rated 5 out of 5 by from works well! installs easily I've been using this for a while now and it works very well, no issues. It was very easy to install. I'm very happy with it. Note, it only supports cold water, so make sure you live in a place that is warm enough year-round.

Rated 5 out of 5 by from Good Value First time customer. Product is well manufactured and a bonus for those who require them. Will recommend to my Asian/European friend/family who are used to water instead of paper.

Does the swash 100 require a filter. Why do you show a filter as related products. What is the minimum supply pressure repaired for the system to operate properly.  Thank you,

Asked by: Elias
Thanks for your questions! Yes, the Swash 100 does require a filter. However, when you purchase your Swash 100 EcoSeat, the required MF Filter is included. You'll find that in the Styrofoam that surrounds the bidet during shipping. The filter usually doesn't need to be replaced often, only when you feel a decrease in pressure. The supplied water pressure should be above 14 psi.

I am really interested in not using toilet paper, so I am wondering if there really is enough water pressure with the Swash100 to thoroughly clean after going number two? And will I have to still use toilet paper in combination with the bidet?

Asked by: phoenixlisa
I have had the Easy Bidet Attachment version of this for many years (it is basically this without the seat, but I believe the mechanics are basically the same) and I can attest to the water pressure being great. I was surprised how much water pressure it has when I got it. In fact, it blows away the Toto $700 seat that my parents have in terms of water pressure. If your house has good water pressure, you will not be disappointed.
