Hard to discern from the photos, but there looks to be a number of plumbing code violations. You do not post where this is, so note that there are slightly different plumbing codes and interpretations.
1. You do not show vents on the floor drains.
2. The shower drain appears to neck down into the floor drain.
3. You need water seals.
4. There needs to be an air gap on the condensate drain.
5. It appears you are using electrical grade PVC (gray color), that would be a code violation as all materials have to be certified for the application.
6. All plumbing components should be of the same material. What are those orange fittings?
7. It looks like you have the incorrect pipe diameters. All of the fixture drains lines except the toilet should typically be 1.5-Inch. You have some of them changing diameters.
8. You need a cleanout at the end of the stack.
9. The fixtures should have vents to the roof, you don't show this.
10. Why is there a condensate drain in the bathroom?
11. The bathroom floor drain is optional for residential bathrooms. The floor drain should be 2-Inch size and vented. The floor drain has to have a trap.
12. You should not have the fixture drains going into the floor drain.
13. Slopes are not shown, but the drains should be vented within 3-4 feet of the fixtures. Allowed distance between fixture trap and vent.
Don't know where you are located but there appears to be numerous problems.
