Hello,

Unfortunately the Alpha JX bidet seat will not fit the Kohler Rosario toilet. We're not aware of any bidet seats on the market that will fit this toilet due to the extreme French curves and short bowl. 

Thanks,

Hello,

The LED night light can be activated on the Novita BH-90 / BH-93 by pressing the top two buttons on the right side of the seat and holding for a few seconds (not remote control) . Instructions are located on page 26 of the user manual.

Thank you!

Hi Jeff,

If facing the toilet, the power cord of the Alpha JX Bidet Seat comes off the right hand side and is about 4ft long.  It should be able to reach the left side of the toilet, but if it's not, you can simple add a heavy duty extension cord (capable of handling 1500W) to the end of it.  You can simply wrap the excess cord behind the toilet so it's out of sight.

Thank you!

Hi Eiko,

The Alpha JX bidet toilet seat will have a .5 second of room temperature water before it rapidly heats up.  Unfortunately this is unavoidable with tankless heated bidet seats and is a tradeoff for being more energy efficient than the traditional tank or hybrid heating type seats.

Let us know if you have anymore questions!

Thanks,

Hi Russell,

The 90 degree hose comes included with the ALPHA JX bidet toilet seat as well as a 7/8" t-valve.  All installation parts will already be included for you.

Thank you,
