Welcome to the Bunnings Workshop community @Namrata. It's fantastic to have you join us and many thanks for your question.


You can take the door with you into your local Bunnings and see if a suitable replacement is available. Simply unscrew the four screws, and the hinges will come off. There's not much I can think of that could fix the cracking issue as it is a failed coating.


Let me mention @redracer01 to see if he has any ideas.

Kind of a Big Deal

Re: Cracked bathroom vanity door due to water

Hello @Namrata 


Bathroom vanity doors for all their strength and finish will eventually degrade and fail. I have yet to see a bathroom door exposed to high moisture not get destroyed. How ever it all depends on how much effort you wish to spend on this particular problem. The doors finish either powder coated or laminated foil seal has failed. Hence the cracks have occurred. Moisture will now enter the door and proceed to damage it. What can we do to perhaps repair the door?


1. Remove the door carefully making sure to put the screws aside so that we can re-connect it later once we have repaired the door.

2. Using sandpaper, sand the cracked side of the door and use builders bog to repair the cracked area. Once it has dried simply use a spray can of gloss white to lightly coat the top of the door until you have a similar or close finish to the rest of the vanity.  I suggest to ask the stores paint specialist in selecting the color of the spray can. We don't want to paint it a different color!

3. Try washing the cracks on the door with light soap and water to remove the brown stains in the cracks. Dry immediately with a dry towel and make sure to use Selleys 150g No More Gaps Multipurpose Gap Filler Tube. Use a flat plastic spatula to gently spread it over the cracks make the filling as light as possible then use a finishing sand paper such as 600 grit to lightly and I mean lightly sand the top of the door until the excess filler is gone. I hope these light repair suggestions work for you. Good luck and stay safe!
