Did he shim under the front apron to level that? Or under the back ledger?
Under the front apron. I'm pretty sure he screwed a ledger into the wall, but I wasn't there so I will confirm

Read the MFG instructions for leveling, The last Kohler CI tub I did said to not shim under the front skirt or apron, voids the warranty. CI tubs are stiff but usually start at the 300 lbs mark, add 175s lb for a person and 350 lbs for the water and that is a lot to put on the skirt and/or apron. There are four feet on the bottom of the tub, and that is where the shimming should be. I use metal shims, no compression and they spread out the load better. Simpson Strong Tie has a few flat products that are galvanized and work well and are cheap and at you lumber yard or big box store. The tub generally should not rest on the front skirt, there is a good chance of chipping the porcelain. Unless you are putting in a vinyl floor the tile will will hide any gap between the floor and front skirt.
