You could, if the extract fan is downstream of the junction of the two vent pipes, and if it has sufficient capacity. But in general, this would not be considered a good idea, as the possibility of 'cross contamination' may be present.
If the fan is upstream of the pipe junction, then it is a bad idea.
You need at least a 3 in. pipe -- shower is 2 in. pipe
2"
You Can but typically the pipe for the shower head that is coming out of the wall is just a short piece of pipe that you should be able to remove easily enough by unscrewing it. Then you can just replace that piece with a new one. == Answer== Do the same as above but make sure your shower arm is not floppy, if it is you could tear up the riser coming to the arm. Be very carefull.
Absolutely NOT you 2" minimum
If you are talking about a roof water drain pipe to sewer it is illegal. If you are talking about a sink drain pipe well that is where they all connect to so yea.

Yes.
Shower pipe is gray

30 cm cheers broA kitchen WASTE pipe is 11/2" in many codes which is utter stupidity as the kitchen WASTE line does become reduced with grease and soap scum depositsIf the WASTE piping is going under ground to connect to the SOIL line (sewer piping) then 2" is strongly recommended as snaking an 11/2 line can be very challenging as the fittings are very short radius
Water won't drain from shower. Either trap or shower drain line is clogged.
It will connect to the PVC pipe into the wall which ultimately will connect into the main sewer line outside.
Normally 2"
No. Australian pipe threads are metric and the US is not.
the shower and bath water comes from two different places so their is two different pipes. Get the shower pipe checked out by a plummer and they cause fix the pipe.
