How to waterproof bath and shower walls?

Hi.

 

I'm ready to form up my bath and shower surround, 

 

Walls:

Floor:

For waterproofing, I've usually used:

Membrane: https://www.bunnings.com.au/bastion-4l-under-tile-membrane_p0363840

For the tape I usually use a mesh, however I see Butyl tape is also used.  As I will be tiling, wouldn't the mesh bet better?  Thinner profile?

 

That look right?IMG_4221.jpeg

Hello @Kurt1 

 

Using a mesh is the preferred method when water proofing. However, before you begin, I suggest checking your local council's rules and regulations regarding water proofing. It might require you to engage the services of a certified trades person to apply the waterproofing as they will need to sign off on it.

 

In regards to your choice of wall and floor liner they should work nicely. 

 

If you need further assistance, please let us know.
