If I have to remove the laundry tub, I do not see how it is attached to the wall. It has no legs. The house was built in 1976.
Maybe a couple of pics. I did a search on installing laundry tubs and all the instructions I found were leg mounted versions. I can't imagine someone mounting one on the wall without the legs if it wasn't designed for wall mount. BUNCH of weight cantilevered out there if full of water.
May need to resort to oh'Mikes suggestion to drill. You can get drill extenders up to 18" long (that I know of, probably longer) that will take hex shank bits. I've had to do that before, usually on drain cup retaining rings.
