Hi , does the whole bathroom wall need to be re done or is 2 coats waterproofing/re tile be ok ?
Hello @Bayside1
Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your bathroom wall.
When the water proofing membrane has been compromised a new homogenous layer will need to be placed over the entire shower. The tiles and shower glass panels will need to be removed and the entire section waterproofed again. Putting a patch over the broken waterproofing will not work.
I recommend engaging the services of a certified waterproofing specialist.
If you need further assistance, please let us know.
