What is the right way to plumb bathroom

[Tite-Tie]

Hi all, I have a toilet beside my bathroom and all the bathroom pipes plumb straight into the toilet sewer just below the bathroom. Is that the correct way to plumb it, or should the bathroom have its own pipes. Any advice would be much appreciated thanks

Your plumber will know.

Depends on how long ago it was done.
Rules and Procedures change over the years.

the reno was done 4 years ago, so does that effect things?

Sound like they've run a line straight in to the toilet, which is good practice and branched off before the WC to pick up the bathroom fixtures, which there is nothing wrong with, unless you mean that the floor waste in the toilet is charged by a fixture in another room, in which case is illegal.
