Installation only requires a screwdriver and takes just 10-20 minutes.<br><br> The sliding block of the toilet bidet’s panel can slide within a toilet seat hole distance range of 136 mm and 200 mm from left to right. <br><br><b>Tips:</b><br> please measure the distance between the two toilet seat holes before purchasing. A distance between 5.35” or 7.87” is suitable for installation.<br><br> <b>All the required accessories contained in our toilet bidet packaging are suitable for installation in 90% of households in the United States.</b><br><br><b>In case of special old-style valves that may require T-type adapters of other sizes, please let us know your requirements and we will help you to solve the problem.</b> <br><br><b>FOOFOO customer service will guarantee your satisfaction</b>.
