with out a clearer picture it is hard to say.

I've put a photo on my website.

You can see where the taps are going to be connected using the flexible hose (the two vertical copper pipes). The bottom of the sink will be about here (maybe a little higher and to the right). The bottle trap will sit about here.

On the right of the picture, you can see the waste pipe. It's got the waste hose for the washing machine on a non-return valve coming out of the top.

The short tube with the plastic bags stuffed into it is just to cap the waste pipe until I've connected it to the sink.

The blue and red hoses coming off the uprights are going to the washing machine (out of shot on the right).

Underneath the pipes on the right is the gas meter, which is one of the things making this kitchen so tricky to fit.
