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.
Cons:
- 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.
