At finished tile.
But...a floor sink is not intended to be used as a floor drain and food borne water should be all that goes into grease lines.keeping it at floor level allows any water to go into grease line.aparently this is a health department issue and varies from region to region
I see your concern, but if you look at the design of floor sinks, you can see that there is a finished rim, similar to the rim of a drop-in kitchen sink. When the floor sink is installed, it is to be placed in an area that is partially concealed by the appliance or sink, but accessible for servicing in the event of a clog.
I agree that a floor sink is not to be used as a floor drain, and in most cases it is used as one when people clean floors and dump water from buckets. That is more of an issue for the end user. The grate that is provided with the mop sink is usually removed and if they cannot control the people who abuse the fixture then they will have to deal with the consequences and expense of clearing mop strings and drinking straws from the drain line as well as the servicing of the central grease trap.
Another option, if allowed in your area, is to put a 4"x3" adapter on the 3" tailpiece that is to receive the drain water (or whatever increasing size applies) and create a hopper that is just above floor level.
In this situation and if you install a floor sink above the finished floor, there must be a good seal around the edges to prevent water leaking between the seam and the floor. A waterproof membrane may need to be installed for installs on a 2nd floor or above.
