Custom Shower Enclosures I Have An Old Fiberglass Shower Enclosure.I'd Like To Tile Over It Is There Any Adhesive That Will Work?

I have an old fiberglass shower enclosure.I'd like to tile over it is there any adhesive that will work? - custom shower enclosures

It's like a strange dimension, which would require a custom installation to a different region, or be removed, and tiles. In the hope that there is a tile adhesive or somthing I can do to make them more attractive. Any suggestion is welcome. Thanks
