Would this be acceptable with respect to IRC 2018? The furnace and humidifier already drain to the floor drain. I'm wondering if I can add a bar sink on the other side of the wall and drain it to the floor drain in a similar manner:
Drain bar sink to mechanical room floor drain?

It would be no different than if you sloped the floor to allow liquids to run across the room into a distant floor drain. In reality it works to drain, but because of the hygienic issue, it is not an approved method.

Thanks. The liquid would not run across the room, but would be in a pipe right up to the drain. What if it used an air gap kit like this? https://www.plumbingsupply.com/airgap-fixture.html

You can do that with condensate but not waste from a sink.
How funny that you wrote this. I was thinking something similar about showers I see in parts of Seattle. There is s floor drain, and in a corner far away they want a shower head. The homeowner figures the water from showering will make it's way to the floor drain across the basement floor.
Now granted, this one is a pipe, but as plumbers we know how that turns out too. The inside of the pipe gets gooey and smelly, Yuck.
That's why we're plumbing enclosed systems that vent through the roof with p-traps to contain smells and only small vertical sections above the p-trap to worry about. And those need cleaning too.
