Good kitchen sink for a slattern?

[Pannacotta]

Am planning a new kitchen and would like a sink which will disguise the fact I am a domestic slattern.

There are always dirty pans waiting to be washed next to our sink and clean post/pans piled up on the drainer (I won't mention the used tea bags and empty cat food tins...)

Would a double undermounted sink be worth getting? Are drainer cut outs easy to keep clean?

It would be nice to be able to have a sink big enough to wash baking trays/fridge shelves in, though I fear a white belfast sink is at odds with my housekeeping.

Any tips/recommendations please?

You can go to a Howdens warehouse and have a look at the doors & a couple of basic set-ups. We had a quote last year when the kitchen was going to be in a different room and it was very cheap, but the builder did do a LOT of business with them.

No nearer a decision! I just wish I hadn't seen the Martin Moore brochure...

Re the sink, we were persuaded to buy a black composite one, which resists scratching. I am also a slattern, my sink usually full of tea leaves. Mine is a double (well one and a half) sink, which is a good thing. However, the colour was a bad idea. Stainless steel, in my view, is the best choice: you can throw bleach down it and it will contrast with your work surface.
I would also never have a sink in an island. We have a hob on our island, which is a much better idea.
