Hey everyone, looking for some cheap DIY advice. I rent an apartment in Sydney and accidentally had a body lotion/soap bottle leak inside my under-sink cabinet. It’s caused some staining and the white melamine coating is peeling and going mouldy in spots.

The cabinet is white MDF with melamine coating — pretty standard apartment stuff.

Now I want to cover the base so it looks decent and doesn’t get worse. I was thinking of cutting a piece of PVC board to fit the floor of the cabinet and siliconing it down.

Questions:

•	Is PVC sheet from Bunnings the best option or is there something cheaper/easier?

•	Should I seal the edges with anything?

•	Any other waterproof lining options worth considering?

Budget is as low as possible. Thanks in advance!
