We had a bathroom reassembled in stages. The bathroom functioned when we moved in 17 years ago but fell apart over time. So we had the floor re-leveled then we had new plumbing and a stall shower installed. Then we had sink, new flooring and toilet installed. Everything worked for 3 days without issue. On day 4, I went to the bathroom and then got in the shower. The shower drain slowed to a crawl and the bottom of the shower filled with water which stayed after I got out. I flushed the toilet after getting which caused it to just fill up and not drain. The toilet does drain down slowly over time. Now the shower always fills up and the toilet only flushes if no one has done anything in there for at least 6 or 7 hours. Even then it rarely flushes down.
The venting for the piping is on the sink which is the first in line moving to the right. Toilet is next and shower is last. I have run the sink and heard the toilet bubble. I have flushed the toilet and watch water back up into the shower. The sink has never backed up from running it.
- Is it possible the shower sunk down from use after the first 3 days?
- Is it possible something is blocking the line somewhere?
- Would anything short of dismantling the whole new bathroom help?
- Could the venting be moved to the shower without destroying the new bathroom, if that is that solution?
We want to use this new bathroom so we can now renovate the old one and repaint and redo fixtures. Can any harm come from using it regularly until old bathroom is renovated (aside from the obvious toilet issues)?

I think the plumber will need to snake that drain (again), perhaps with a bigger snake. They should snake from the cleanout under the toilet towards the sewer or septic tank (whichever you have).
