Kitchen sink modelling I am planning of a renovation, specifically my kitchen and I thought in doing it in Blender and UE4 since that would be a great opportunity to learn the programs as well.

I have managed to model the house (walls, windows, cabinets etc) and now I am in the process of modelling the appliances and stuff. I managed to do a fridge and now I am trying to model the kitchen sink in the photo:


I began with a simple plane and I managed to do the two bowls of the sink, but soon I ran into a problem because I noticed that this sink has three layers/planes or at least that's what I think.

So my question is this: Should I try and create more loop cuts in the specific plane and try to extrude/move/delete etc the edges or vertices? Or should I create the three layers separately in planes and join them together afterwards?

If I create those three planes, how could I "bend" the edges of my plane so I could get the shape of e.g. the second plane?

Is there perhaps an easier approach in this? Or a resource (e.g. article or tutorial) explaining something similar?

Please don't get me wrong I merely ask for a suggestion, not for someone to write a tutorial! :)

Thank you in advance and please excuse my English, it's not my native language!
First use the picture as a background, draw all the lines, use shift ctrl B on vertices to create round corners, then join the vertices to fill the whole shape, then you can begin to extrude down. Afterwards, create some bevel to sharp the edges before you put a Subsurf.
