Welcome to the Bunnings Workshop community @gforce. It's fantastic to have you join us and many thanks for your questions.
You might like to start by looking through some previous discussions within the community on painting tiles. We've seen some fantastic results using the Dulux Renovation range, and I trust you'll find this step-by-step guide useful: How To Paint Bathroom Tiles.
Please don't hesitate to let us know if there were questions that you had.
Let me also extend my welcome to the Bunnings Workshop community.
I trust Mitch's response was helpful. If you need further assistance, please don't hesitate to let us know. You might like to share photos of your bathroom so members can see what you are working with and make more informed suggestions about next steps in your renovation project.
