I need to set a tub, well mine is a 200lb cast iron shower receptor, but I assume the installation is the same. The manufacturer (Kohler) simply says to move the receptor into position and shim as necessary to make it level.
There are four rather small feet under the receptor, I'm a little worried with all the weight of the receptor and occupant that the feet will push into the plywood floor a bit. Would it be ok to put a metal plate under every foot and then start shimming?
Second, when type of shims do you use? I have an abundance of metal electrical box cover plates (4"X4"), any reason why I can't use those?
Thanks Mike. I ended up putting a plate under each foot to start, this way I won't have to worry about the foot pushing into the plywood over time. The feet on the Kohler are only 1/4" inch wide so I feel safer now.
I had to add 4 plates to one of the front legs and 1 plate to the other front leg, it came out nice.
