Some toilet seat bolts are shorter than required to install the bidet attachment
1) Install longer toilet seat bolts that will accomodate the extra space of the bidet attachment
2) We strongly recommend you our cold bidet attachment X1, which is our New Design.
X1 is non-electric bidet attachment, which is our ORIGINAL new design. It has singel nozzle with water pressure adjustable. We use the 3M stickers to paste the bidet onto the toilet seat, so you don't need to unscrew the toilet seat. The installation is really easy and simple.
