    Solvent waste pipe has an outside diameter of 43mm whereas polythene waste is 40, maybe 41mm.
    A compression fitting will accept both.

    Nope you're trying to mix Push Fit and Solvent Weld waste if those are the actual items you have bought. The 2 types are not compatible, you will need to use one or the other, or join with compression waste fittings, not ideal if under a floor, use solvent weld).

    43mm is the outside diameter of the pipe, it is 40mm internal diameter.

    I would also be cautious about connecting a bath and shower on the same run, seen it before when the pipe has blocked up, a full bath has been let go and erupted in the shower. The bathroom was flooded and water was coming through the ceiling below by the time the occupier had realised. Best run them separately if you can.

    Its on the ground floor and I can always get access to it via under bath.

    So with the T fitting I bought whats the pipe I need? Any links for the pipe please?

    Will this push into my push fittings?

    The shower waste has a 40mm outlet too

    Yes, the push fit pipe will fit into the push fit tee.

    I would also recommend that you avoid using push fit and at worst use compression fittings, if you don't want to use solvent weld.
