Ø of the bung hole made on demand

We can make on demand a hole for classic bung (60 mm) or for a bung with waste basket (90 mm).

Countersunk recess underneath to fix the tap
This recess (invisible) is made under the tap hole, below the sink. It allows mixers with built-in spray to be fixed, for example, or a fitting whose thread does not have to be lengthened (taps with tube).
