Let customers speak for us
from 141 reviewsI'd purchased a bidet from another company & started second-guessing my purchase. While reading online reviews I ran across a stellar review about Neal @ EverFlow Bidet. I gave Neal a call. He was magnificent. My husband has Parkinsons with balance issues, along with incontinence. We have support rails on all 3 of our toilets. Our concern - could we use our type of support rail on the new bidet? Neal asked me to send him a photo of our support rails so there was no confusion about the type we had. The answer was no. However, Neal researched on-line & found another portable, collapsible support rail that might work & e-mailed me options. In follow-up conversations, Neal worked with me to suggest different bidet styles & reviewed the pros & cons of each one. We finally made our purchase knowing we could have a bidet without giving up support rails. The bidet arrived. Neal had mentioned he pays extra for packaging to ensure the bidet arrives at our door safe & sound. That comment was not an exaggeration. It took our plumber 2 hours to remove old toilet & install new bidet toilet combo. The manual from ToTo was easy to read with clear graphics. The product is quality to match Neal's customer service.
Is a great product, easy install, ran into some shipping issues but folks at Everflow were great to work with, they ultimately got things resolved so that I received the product in a timely manner.
TOTO S2 Electronic Bidet Toilet Seat
If you’re looking for best-in-class customer service, this is your place. EverFlow has earned my business for life.
We ordered a high-end bidet from EverFlow about two weeks ago, and the product showed up within days, not weeks. Unfortunately, the courier damaged it during transit. I was pretty nervous about what dealing with customer service on an issue like this was going to look like.
Much to my surprise, when I called, I ended up speaking directly with the owner of the company. He was incredibly kind, apologetic, and genuinely concerned about making the situation right. There was no runaround and no arguing over whose fault it was. He simply took ownership of the problem and immediately got a replacement unit on the road.
From the original order to receiving the replacement, the entire process took barely over two weeks.
That is one of the most impressive customer service experiences I’ve had in a long time. Problems happen, especially when third-party freight companies are involved. What separates great companies is how they respond when something goes wrong.
EverFlow absolutely nailed it. They’ve earned a customer for life.
Neal, the owner of Everflow Bidets was a huge help picking out the best choice for me. He answered the phone personally on Saturday morning and we had several conversations to arrive at the best choice. Best customer service I have experienced in a very long time.
Replaced all 4 toilets in our home and all are performing identically after more than 6 months in service -- a testament to the product's overall quality control. Control panel is easy to navigate for daily use while "set & forget" functions (seat heat & energy savings settings, night light, etc.) require reference to the owner's manual. Neal was refreshingly informative and even passed some bulk shipment savings on to us for the palletized arrival. Couldn't be happier!
TOTO S5 Electronic Bidet Toilet Seat
Have really enjoyed my bidet ever since it was installed. Especially during the winter months.
Very good service provided by Mr. Niel. Highly recommend their products and services . I would definitely go back for future purchases.
I didn’t know a toilet could change my worldview, but then I met the TOTO S7A Washlet.
This is not merely a bidet. It is a tiny, porcelain-adjacent butler who appears to have been trained at a five-star Japanese spa. The seat warms itself. The lid opens like the arrival of royalty. A gentle pre-mist prepares the porcelain. And then, when the moment arrives, a perfectly aimed stream of warm water performs its exceedingly dignified work.
There are settings. So many settings. At this point, I am less concerned with “going to the bathroom” than I am with curating an experience.
The heated seat alone feels like a small act of civilization. The deodorizer quietly handles the evidence. The dryer offers a dignified conclusion. And the whole production happens with such technological confidence that you begin to wonder why the rest of your house isn’t also operated by a Japanese engineer with impeccable manners.
The S7A has ruined ordinary toilets for me. A conventional toilet now feels like a primitive ceramic bucket—an artifact from an era when humanity apparently believed wiping with dry paper was the pinnacle of sanitation.
Five stars.
Ten if the bathroom had them.
TOTO S7A: because once your throne has heated seating, a spa-quality wash, and an automatic lid, civilization has officially peaked.
A new shoulder on March 4 2026 and the first bidet installed three days prior. The second one two weeks after the surgery. Both work perfectly. Thinking about putting one in our second home in Calistoga. Highly recommend a bidet.
Bought 2 of these and love them! Couldn't be happier and love all the features they offer... especially love the personal settings!
So far so good. Neal was very helpful when we called with questions. Install went smoothly. Does this come with a remote?
Growing up i am used to use water to clean the tushy and moving to US was a challenge as there is now hand shower or wet wipes. Once i got to know this bidet exists, i bought them. I changed every bothroom and now my kids don’t want to use toilet anywhere else as the seats keeps you warm especially in cold new england winter nights and cleans you thoroughly. 6 years and still working as new!
After travelling to Japan for vacation a couple of years ago and seeing TOTO bidet toilets everywhere, we decided that we needed one of them in the home we were moving to last year. TOTO is a proven high-quality name and we chose to settle for nothing less for a product we'll be using daily for the foreseeable future. We were fortunate to find Everflow, which provided us with the model we wanted at a great price and delivery timing. We couldn't be happier with having chosen Everflow and TOTO.
