A: Yes - I installed several of these on doors using hollow door anchors instead of the anchors provided.
A: I don’t believe so but you could write or email the company!
A: No, it does not come in a larger size.
A: Yes, this can be mounted on a porcelain tile inside a shower.
A: I don't know if the manufacturer recommends that place for hanging this fixture. The hanging device doesn't look to be rust proof and I'm not sure how to water prove the holes necessary to ount the device to the wall. You might want to check with the manufacturer directly. Hope this is of some help.
