1. How do I determine my toilet type?

2. How do I know if my bowl is round or elongated?

Older or basic toilets are round.  The inside of the round toilet bowl is usually about 11 inches around.  More modern or deluxe toilets have an elongated bowl that is about 2 inches longer than it is wide, it's a noticeable difference you can see. 

If you're still wondering, you can measure from the front of the toilet tank, to the very front of the toilet bowl.  That measurement will be about 17+ to 19 inches if the bowl is round, and 19.5 to 20+ inches if your bowl is elongated.

The Swash line of high-tech toilet seats combines the latest innovation and design to bring you a new level of luxury and hygiene.  Better than a conventional toilet seat or bidet, the Swash features a heated seat and delivers a warm water wash with temperature, pressure, and pulsation adjustability.

Eco-friendly: The Swash reduces toilet paper consumption 50 - 100%

The United States uses over 3.2 million tons of toilet paper annually. 54 million trees per year are cut down to keep up with demand. In addition to deforestation, the production process itself is very destructive.

Each roll of toilet paper produced uses:

1.5 pounds of wood
37 gallons of water
1.3 KWH of electricity
Harmful chlorine, sulfur, and calcium carbonate

Having a Brondell Swash in your home will reduce toilet paper consumption by 50 - 100% via the effective cleansing of the warm water wash and optional warm air dryer. In addition, a Swash only uses an average 5-7 cents of electricity per day - even less when the power saving feature is activated.

What is a Swash?

A Swash is a high-tech toilet seat that utilizes two retractable water wands to provide men, women, and children a fresh and hygienic cleansing of posterior and feminine areas.

How does a Swash work?

The Swash replaces your existing toilet seat. Better than a conventional toilet seat, it has a heated seat and delivers a warm water wash with temperature, pressure, and pulsation adjustability. 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 push of a button through side-mounted controls (Swash 400, 450 & 550) or through a remote control (Swash 600, 700 & 800). The Swash 550, 600 & 800 also include a warm air dryer for a complete "hands-free" experience.

Where is the water stored that is used for the bidet wash?

The Swash 400 and Swash 600 water is stored in a reservoir located at the rear of the seat. The Swash 450, 550, 700 & 800 uses an instant heating coil that provides "endless" warm water washes.

What is the weight limit of the Swash?

The Swash 400 and Swash 600 will support users who weigh up to 270 pounds. The Swash 450, 550, 700 & 800 will support users who weigh up to 320 pounds.

What colors is the Swash available in?

The Swash 400, 450 are available only in white. The Swash 550, 600, 700 & 800 are available in white and biscuit.

Helping Women Stay Clean, Every Step of the Way

The Swash, with its dual wand system, leaves women feeling clean and rejuvenated. The warm water cleansing is especially helpful during the course of menstruation, and many women find its soothing properties can help alleviate the discomforts associated with constipation, yeast infections, and irritation. The Swash is particularly helpful during and after pregnancy to help soothe anal irritation, hemorrhoids and general discomfort. Many women also find the Swash to be a comfortable and hygienic way to clean themselves following intercourse.


The Swash provides an effective and natural way to eliminate vaginal odor throughout the month, and it is particularly useful during a period. Menstrual flow is not simply blood; it also contains cervical and vaginal mucus and degenerated endometrial particles. When this fluid comes in contact with bacteria in the air, it begins to decompose and can become odiferous The gentle cleansing of the feminine wash rinses the area clean, removes any odor and helps to make what can be an uncomfortable time of the month a little more pleasant. In addition, the Swash and its dual wand system also serve to keep the rectal area clean.

Yeast Infections:

Yeast infections can cause itching, discharge and unpleasant odor. While the Swash can't cure a yeast infection, it can provide soothing relief from the symptoms while treatment is being received from a gynecologist or over the counter medications.


The Swash is ideal for pregnant women for many reasons:

Hemorrhoids -- Due to increased weight gain during pregnancy, women often develop hemorrhoids. Hemorrhoids are veins that swell and protrude around the anus. The symptoms are a painful burning sensation, itching, swelling and bleeding. Toilet paper often exacerbates hemorrhoid symptoms. The Swash's warm water posterior wash and air dryer eliminate the need for abrasive toilet paper and keep the affected area clean and dry, providing comfort and relief from tenderness and irritation.

Lack of Mobility - The changing shape and increased weight gain during pregnancy can make it awkward and difficult for expecting mothers to thoroughly clean themselves. The Swash's dual wand system provides excellent cleansing in both the feminine and posterior area.

Cleanliness Before, During and after Delivery -- Women need extra help with cleanliness during pregnancy. Before the baby comes, women can experience the loss of the plug of mucus, water breaking and loss of amniotic fluid. The gentle cleansing of the Swash provides comfort and relief.

There are also massive physical changes that occur during the first few weeks after giving birth which can be comforted by the Swash and its gentle warm water wash:

Lochia -- The term "lochia" is the bleeding that occurs as the uterus sheds its lining after the birth. This occurs whether the birth is vaginal or cesarean. While women have traditionally been told to expect their lochia to last for 10 to 14 days, recent studies have indicated that most women experience lochia for at least a month after the delivery, and many for as long as six weeks. This means exceptional feminine cleaning is needed during this time, and Swash delivers that even when you're sleep deprived or holding a baby with one arm.

Perineum - The perineum may have swelling, bruising, or other complications that can be soothed by the Swash.

Urinary tract - The doctor will want to ensure that there aren't any delivery-related bladder problems caused by trauma to the area during the delivery, the effects of certain anesthetics, and so on. The Swash delivers unparalled hygiene for urinary clean-up.

 Helping Men Stay Clean, Every Step of the Way

The soothing warm water of the Swash's posterior wash helps relieve discomfort associated with constipation and hemorrhoids and provides men with a means for improving their anal hygiene. The warm air dryer and comfy, heated seat make time spent on the "throne" all the more enjoyable!

Medical Needs

Loss of mobility, both temporary and permanent, can be painful, frustrating and often times make it difficult to perform everyday functions that were once very easy, such as going to the bathroom. Partial or total mobility loss may result from conditions such as arthritis, broken bones, Dupuytren's disease and hernia and rectal surgery. Over 70 million Americans have some form of arthritis or joint inflammation, often translating to a serious debility. In addition, Dupuytren's disease, an abnormal thickening of tissue beneath the skin in the palm of the hand, may eventually limit movement.

The Swash allows people suffering from conditions such as these to regain the comfort and dignity of using the toilet by themselves.

Benefits for Hemorrhoid Sufferers

Hemorrhoids are veins that swell and protrude around the anus. The symptoms may include a painful burning sensation, itching, swelling and even bleeding. As many as 10 million Americans suffer from hemorrhoids; most of them between the ages of 45 and 65, but over half the population will experience them at some point in their lives. The good news is you can now find hemorrhoid relief without resorting to surgery!

The Swash eliminates the need for abrasive toilet paper when using the toilet. The warm water jet and warm air dryer clean and dry the user, providing great relief from symptoms such as tenderness and irritation. Whereas sufferers with traditional toilets often dread going to the bathroom and try to wait as long as possible (causing further complications), Swash owners may actually look forward to using the toilet because it is a pleasant, soothing experience.

Relief for Irritable Bowel Syndrome and Incontinence

Skin care is very important for incontinent patients and those with IBS; however, cleaning with toilet paper or soap can dry and irritate anal tissue. The Swash allows multiple washings without the increased skin abrasion and irritation caused by other methods.

Help for the Discomfort of Crohn's Disease

Crohn's disease causes inflammation and irritation in various parts on the gastrointestinal tract. With this condition can come a frequent need to use the toilet. The Brondell Swash allows complete and gentle cleansing after each bowel movement without harsh, abrasive toilet paper.


Rocky, Paula, Wendy, Ryan, Austin, Carson and Hunter Raynor Half Moon Bay, CA "My wife and I ordered a Swash for our masterbath. We didn't tell our six-year old twins about it but in no time we were waiting in line for our own bathroom! The boys loved it so much we ordered one for them. My wife loves the Swash because it makes doing the boys' laundry much easier and cleaner!"

Dr. Marcus Laux, Naturally Well Today "The Brondell Swash is a wonder of ergonomics and hygiene enhancement. Plus, its for use by men as well as women."

J. Meyer "In the wintertime, I can't even TELL you how good it feels to sit on a warm toilet seat. AND I don't feel NEARLY as clean when I use a toilet anywhere else besides my own 'Swash-equipped' bathroom!"

Byron & Virginia B "The Swash is an excellent product and is effective in both concept and design. We like it and highly recommend it!"

Anthony LoGrande, Designer, New York "With clean styling and luxurious features, the Brondell Swash provides a great solution for designers and home remodelers alike."

Deborah Lyn Levich, MD, MBA "I have the Swash installed in the new bathroom of my gynecological practice. My patients love it. They find it comfortable, easy to use, and "fun". Washing with water is a much more hygienic way to clean feminine areas following urination, during menstruation, and after intercourse. And, because water is less irritating than dry toilet paper, it is ideal for post operation care and during and after pregnancy."

Joni L., Coldwater, Michigan "Being a handicapped senior who recently had shoulder replacement surgery, I have found it challenging to get around the bathroom. The Brondell Swash is a God-send in my particular situation. But it's not just beneficial to me. I think all seniors and handicapped people will benefit from the Swash's easy-to-use and hygienic features."

K. Noel, Naperville, IL "It is great. It's like, once you try business class, it is really hard to go back to coach!"

Mark Carroll, Atlanta "I do not think you realize what a niche you have, nor the pain the elderly have with bathroom requirements, both men and women. Your product is a blessing in times of need. Every toilet in every nursing home in the U.S. should have a Swash. I am not only a care giver, I am an architect. I have designed care giving facilities, and have met the people living there."

Swash User "Having IBS has been a monkey on my back(side). The Swash has given me a new take on my post-movement lifestyle. The toilet is often an excruciating exercise for me, but the Swash provides a nice refreshing finish."

Don F., Santa Rosa, California "Equal benefit for male and female users. The improvement is the obvious improvement over standard TP use, not to be too graphic, but TP seems kinda dirty now, and we hate using the facilities at work, preferring to use them at home!"

P. Fink, Truckee, CA "It's a great solution if you like bidets but don't have room or plumbing for one."

Kevin C. "My mother-in-law, has had multiple intestinal cancer surgeries and needs to use the toilet more often than most. The Swash makes it more comfortable for her so that she does not need to use rough toilet paper."

Melanie B., San Francisco "Clean feeling, low maintenance, well made overall. I mentioned the clean feeling, right? That's really reason enough..."

Scott Epstein, Denver, CO "My entire family agrees that the Swash is the only thing in our house we could never live without again!"

Installation and Fitment


Will a Swash fit my toilet?

The Swash fits over 98% of residential toilets. Swash will even fit highly contoured one-piece toilets. Unless you have a toilet with a square bowl or one that is wall-mounted, the Swash should fit your toilet. Just check your toilet type, round or elongated, and choose the appropriate Swash.

Please refer to our toilet fit chart for specific fit information. If you don't see your toilet model listed, please email us or call 1-888-542-3355.

What installation is required?

Standard installation is easy and takes less than an hour. The high-level steps include: 1) turning off the water valve at your toilet; 2) removing your existing toilet seat,; 3) installing the mounting bracket; 4) attaching the Swash to the bracket and connections. The Swash includes a T-valve installed directly below the toilet water tank to direct filtered household water to a small reservoir within the unit. The Swash operates on standard 120 volts AC and is equipped with a four foot cord. Click here for detailed installation instructions.

Do you offer professional installation services?

For customers who wish to have their Swash professionally installed, Brondell's preferred installation partner Handyman Connection is offering standard installation for as low as $59 and up to $50 off GFCI outlet installation. Please see offer in shipping box  for more details.

Do I need an electrical outlet?

Yes. You will need a three prong GFCI grounded outlet (e.g., outlet that has a safety breaker in it -- same as those found in kitchens). If your outlet is more than four feet from the toilet, a grounded extension cord is necessary. For those customers interested in installing a new outlet specifically for the Swash, the optimum location when facing your toilet fixture is to the left side of the fixture underneath the toilet tank. Brondell's installation partner, Handyman Connection offers up to $50 off GFCI outlet installation.

Using and Maintaining the Swash

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. For complete cleaning, the Swash can be easily detached from its mounting bracket. Although Swash wands are self-cleaning, Brondell recommends they be cleaned with a soft brush monthly or as needed. Brondell recommends water filters be cleaned occasionally, which will vary depending on your water source.

Is a Swash safe and reliable?

The Brondell Swash is UL certified and Brondell warrants its products for one year from 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.

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. Elderly and handicap people can use a Swash because they are so easy to use and so effective in their ability to provide complete cleanliness.

Does the seat stay heated at all times?

This is controlled by the user. The seat can be set as follows:
a. Off (no heat)
b. Heated to one of three temperature settings, remaining on at the prescribed setting.
c. To Energy Save mode, which sets the seat to off (no heat) for a specific time period.

How long does the wash cycle take?

Effective cleansing is generally accomplished in 15 to 25 seconds.

How long does the warm water last?

The water reservoir on the Swash 400 and Swash 600 is good for about 25 - 30 seconds of warm water at full spray pressure. After this time the spray temperature transitions to ambient or room temperature. The Swash 450, 550, 700 & 800 uses an instant coil heating system and provides "endless" warm water washes.

What is the difference between the "for him" and "for her" posterior washes on the Swash 600 remote?

The "for him" and "for her" buttons allow two people to save their own unique spray pressure settings. However, there is no difference in functionality between the two.

Do the wash wands ever "get in the way"?

No, the wash wands are only extended during the cleaning cycle. At all other times they are housed in the unit to avoid being contaminated. As a further safeguard, the wands clean themselves with a high pressure spray of water before and after each use.

Medicare and Accessibility

Is the Swash covered by Medicare?

Not at this time.

Does the Swash work with toilet risers or platforms?

Yes, the Swash is compatible with the Carex Toilet Seat Elevator by Rubbermaid and the Hinged Elevated Toilet Seat from Ableware Independent Living.
