Hi @newbeginner,
Thank you for your question about fixing a broken bath.
Do you still have the piece of the bath that has cracked off?
If so, you could simply glue it back in place with some Selleys 3ml Power Grip All Plastics Glue. There will still be a slightly noticeable line where the break has occurred, but this could be touched up with Rust-Oleum Tub And Tile Touch Up Kit to remove the line.
If you don't have the piece that has cracked off, you could use PC-11 56g White Epoxy Paste to fill the gap and then sand and paint it to match.
Let me know what you think and if you have any further questions, please don't hesitate to ask.
Jacob
