I have a deep drive 11mm somewhere bought for just this. . Couldn’t find it without going into far greater search than I wanted to yesterday. Luckily once the drawer was out of the base unit, I could get on the mounting nut with a std ring spanner. Other option would have been to cut the screw which goes into the tap base much shorter and use std socket.

easy to change using long box spanner from toolstation . a tenner for 3 diffrent sizes
