Ikea Yddingen tall cabinet - What are the dimensions?

I would be interested to know how wide the sink actually is. On the Ikea page it says

Width: 74 cm
Washbasin width: 70 cm

How deep (opposite of wide) is the actual washing area?
How deep (shallow) is the basin?

Can the sink be used without a cabinet underneath, or does it look unattractive like, for example, with Odensik?

With Waschtisch the cabinet underneath is meant, so the basin is 74 cm wide.

I can only estimate the other dimensions as well. Depth of the basin approx. 30 cm, height 11 cm.

It doesn't work without a base. How do you want to attach it then?

Thank you very much for the information. I meant of course base cabinet, not signature. I had hoped it could be mounted on the wall. I am looking for an affordable 80 cm wide sink of this kind. And all those that are considered start at a minimum of 150 euros.

A sink "of this kind" is a rather vague description. Is it enough for it to be rectangular with a certain width, or do aspects like aspect ratio, height, etc. also matter?
You should best pick a few sanitary online shops that have a decent search filter (e.g. Emero, Reuter or any other). There you can experiment with parameters like size and shape and see what is available on the market and what prices are asked for ... the Laufen Pro series might be within your price range.

Yes, you're right, that was probably a bit vague. But you already recognized it correctly, I really like these square ones. Ideally, they should be 80 cm wide, but yddingen with a width of 74 is also fine. I will then take a look at the online shops you recommended. But in the end, I have to ask one more time for dummies: Yddingen doesn't have holes from the factory to attach it to the wall? Although you could surely manage with brackets and stuff...
