Alpha Bidet

The ALPHA JX bidet toilet seat from is the culmination of over a decade of experience in the bidet industry.  Starting from scratch, we took all the most popular bidet seat features our customers ask for and stripped away the fluff to create the most complete premium bidet toilet seat yet: the ALPHA JX.

best bidet  Don't just take our word for it. In a rigorous 3 month test of 18 of the most popular bidet seats on the market, CNN Underscored named the Alpha JX the Best Bidet Seat of 2021. The JX beat out the competition from TOTO, Bio Bidet, Brondell and more.

"The Alpha JX bidet seat was the best overall bidet seat we tested, featuring the most desirable technologies at the lowest price." [read more]

Advanced Features

The ALPHA JX bidet seat is built around an energy efficient, tankless water heating system.  This instant heater provide endless, on demand warm water with little to no startup lag.  During the wash, an air pump mixes bubbles into the wash stream to provide a more soothing feeling, and uses up to 40% less water compared to tank type bidets.  Beyond that, we designed the ALPHA JX to be whisper quiet during operation—no more loud motor and pump noises.

The ALPHA JX features a photo sensitive light sensor that senses ambient lighting conditions in the bathroom.  When it’s dark, the seat’s LED night light will illuminate the bowl for easy night time bathroom trips.  The light sensor is also used with the JX’s SUPER power saving mode to reduce energy use when idle.   The seat is equipped with a strong warm air dryer w/ adjustable temperature that can fully dry a user in under 2 minutes. 

EASY WASH – We programmed the ALPHA JX remote control with an exclusive EASY WASH button that activates a full pressure rear wash with nozzle oscillation.  This button is perfect for folks who want the best possible clean without having to adjust any settings.  Just press EASY WASH and relax.

WASH & DRY – Again, we wanted to make the ALPHA JX both easy to use and accessible.  The special WASH & DRY button on the remote control will activate a full rear wash cycle, stop, and then a full drying cycle and then stop—all at the press of a single button.

Smart Design

Beyond its advanced functionality, the ALPHA JX sets itself apart with smart design cues.  No more big, bulky bidet seats with flimsy lids that you have to worry about around kids and guests.  The ALPHA JX has one of the slimmest profiles on the market making it easy to actually fit your bathroom décor.  Its body is made with a high grade, anti-bacterial polypropylene resin that’s vibration welded.  This creates a surface that is attractive, durable, and easy to clean.  The lid is specially contoured and extra thick, making it safe to sit on—supporting up to 300lbs.

Another important factor that the ALPHA JX addresses is its almost universal fitment.  Due to its slim, low profile design, the ALPHA JX can fit on virtually any residential toilet, even some 1 piece toilets with a French curve design. 

The ALPHA JX’s nozzle system is both sanitary and effective.  The self-cleaning aluminum nozzle has separate sections for the front and rear wash functions.  It is treated internally with an anti-bacterial nano silver compound for added sterility.  The nozzle tip is also removable for easy cleaning and maintenance.

Kohler San Raphael - The JX elongated will fit about 70% of the time very well.  The other 30% of the time, it won't fit at all. This is due to Kohler manufacturing this toilet to different specs over the 30 years it has been in production, unfortuntely we cannot guarantee fitment

Kohler Rialto - The JX round will be able to mount most of the time, but it is not an ideal fit. There will be 1" - 2" of overhang in the front of the bowl

Kohler Santa Rosa - The JX elongated wiill be able to fit pretty nicely. There will be a 3/4" overhang in front due to the Santa Rosa being a "compact elongated" toilet bowl shape, not a true elongated.

Glacier Bay N2420 - The JX elongated is a very good fit on this toilet.

Very happy with it.

Works simply and efficiently. Happy with remote.

Not 100% satisfied.

Does not clean completely. I still get soil Mark's on my briefs. No beep after dry & wash cycles.

Raymond Colby
First bidet, lives up to expectations.

Seat is nice and warm, water has a good pressure and is also warm. Haven't noticed the warm water run out and it almost instantly is up to temperature. The front nozzle is useful for women.

Everyone needs this!

This is amazing; heated everything, works without fail, every time. I may move my home office into the bathroom now. Seriously, wondering how I've gone the past 55 years of my life without this. Easy to install, have had no issues, works great! I have a digestive disorder which causes me a lot of trips to the bathroom throughout every single day. I hadn't ever considered a bidet, but a friend suggested it, sent me a YouTube video about them, and I still wasn't sold. (Even though the guy in the video was very convincing when he said, "If you got poop on your hand, would you just wipe it with a piece of toilet paper and move on with your day?".. um. No. I would wash my hand with water. OHhh.... yes... got it. But recently I took a trip, and the hotel room had a heated-seat, heated-water bidet and I had no choice but to use it, and... SOLD. I loved it. Love this one, no complaints, can't say enough great things.

Don't Knock It Until You Try IT

Ok, I was very skeptical that a bidet seat would be helpful. After all, my mom and dad never had one and as a matter a fact, I never knew of anyone that had one except those europeans that had them everywhere as a separate unit .Finally decided to try egged on by the supply chain crisis which led us to hoarding toilet paper regardless of price.

Much to my surprise, this bidet toilet seat (once I tried it) made me wonder why I didn't get one sooner! Here is why: 1. Reduces toilet paper use by 90% (I now have enough stored for three years) 2. Cleans efficiently and thoroughly and eliminating skin irritation caused by overwiping. 3. Heated water and seat are extremely comfortable. Sure, I had to install an outlet next to the toilet but it was sure worth it. 4. Fan dry works well for me.

What I would recommend as an improvement is even though I like the light to guide me to my frequent nightly visits, being able to adjust the intensity and/or the color would be helpful. A blue light would be better. (You know, blue water, right?)

I like it so much, I ordered a second one.
Last thing, I did have an issue and Bidet King solved it for me very efficiently.
