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. 

BOWL MIST *NEW* – With the touch of a button, the ALPHA JX will spray a fine mist all around your toilet bowl to create a slick surface. This prevents fecal matter from sticking to the bowl, keeping it cleaner with no effort. 

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 stainless steel 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.

The ALPHA JX fits all 2 piece toilets and most 1 piece toilets, including some with French curve design.

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.  

To determine what type of toilet you have, please consult the Bidet Toilet Seat Fitment Guide.

Easy assembly, great function

This would’ve been a full 5 stars except for a small fit issue where the bidet seat is longer than the toilet bowl. Doesn’t impair function just a minor annoyance.


I love it, it’s great❤️

What are you waiting for?

I put off getting this bidet. As a woman, I was worried about installing it myself. I finally pulled the trigger and it sat for a couple of weeks while I gathered the courage to open the box. On a rainy Saturday, I gave myself the whole day to deal with it. I opened the box, the instructions were easy to follow, the whole project was uncomplicated..I was done in a hour. Don't wait, this is so much better than the "bum guns" in Europe. I LOVE it!!


Love the simple and comfortable function. Don’t know how I lived without one.

A final solution to my French Curved toilet

I have a Horow HR-0080 which is one piece with French curve, the hole center to tank is around 2 inch but the clearance of the edge is only less than 1 inch, see pic. I purchased a Brondell 2200 from Costco but seat it way over the edges to install, so I returned it. Contacted both bio-bidet and Brondell customer support to see if any of their product may fit, the answer is clearly no, they said none of their product can fit french curved toilet even though on their advertisement picture is one of such. Finally I found this ALPHA JX from a thread in Reddit, it saved my toilet. The bracket is perfectly shaped towards the contour (see in the pic), after installing the bidet with some alignment, there is even some spaces left (see pic).

For the bidet seat itself, Pros:
- Very comfortable to sit on.
- Warm water, warm seat and warm air dry are all heated quickly, better than what I had before (own two biobidet and one brondell)
- Nozzle Oscillation is easy to set up by pressing twice and even come with wash/dry one button function.
- Self nozzle clean before and after use is a plus.
- The base bracket has no rachet on the metal plate, so it is not stable purely by the pressure of screws.
- Lack of user customization for multiple users and no deodorizer at this price tag.
- No quick release function for uninstallation, lift up at an angel takes some practice and is not secure.

Overall, this is the only one I can find on the market, definitely recommend it. And I am very thankful for the customer support from BidetKing, very helpful for me, directly recommended the right product and saved me a bunch of trial-and-return purchases.
