New ground floor toilet, shower

[Mikest]

I need some help please, hope someone can help.
Im building a ground floor shower/wet room with a toilet sink and a bath.
Currently im at the dpc level and ready to concrete, but i need advice re the pipeing for the bath + shower + sink.

I have a verticle 4inch pipe where the toilet will be.
Should i be plumbing the sink and shower and bath to this pipe? or do i have to dig to main drain line and bring another 4inch pipe to the room to with i should make the connection. Please advise. Should be starting on it in the morning.

A lot more info. reqd. Is this a new build, an extension or refurbishment?
If you post pics and a plan view of what you propose and whats existing, esp. the drainage arrangements, then perhaps we could help better.

It is possible to boss onto a 110mm stack though i would make sure the wet room waste is of the deep seal variety and is suitable for this type of connection, i.e. beneath the toilet outlet.
