Bad redesign - sanitary equipment from which manufacturer?

A completely normal connection fitting fits there. 110mm is standard and the Venticello has 102mm which is also standard. For the inlet, however, it should be 45mm. Measure there again carefully because 45mm is standard at Geberit.

Perfect, you have helped me a lot. I have one last point.

There are 2 different washbasins from the Subway series, one comes with a template and the other does not? (Article number 711360 and 71136G)

We want to mount the washbasin on the wall and combine it with an Ikea vanity unit. Do you know what the differences are between the two?

Do you know where the differences between the two lie?

This is the difference. One sink can be used as a countertop sink because of the ground (and therefore flat) underside. The other is for classic wall mounting.

Every manufacturer and every series has different actuator plates.

Oops. Yes, that's what I mean, I have read that as a problem more often :)

Okay thanks and if I install the washbasin into such a base cabinet I don't necessarily need a ground surface underneath, right? It rests at most on the edges, in the middle it is hollow.
