Combing shower & sink waste (can you)

[5oysterman2]

Morning guys, in the planning stages of doing our bathroom up. Getting rid of bath etc & replacing with a shower.

I have put 3 photos up & what I was hoping to do is to lower sink waste to behind soil pipe, so it can be boxed in.

The waste from the bath is staying at the same height when shower is installed on a raised platform. What's the best/easiest way to connect lowered sink pipe. The soil stack or existing bath waste. Hope i have explained it properly, if not just ask. Cheers Doug

I personally don't have a preference , can't say I have noticed any real difference whichever I have used.
