A true remedial strip-out means carefully pulling out the old shower screens, vanities, floor screed, tiles, and old plasterboards. This is the only reliable way to find the hidden pathways where water has been escaping, check the plumbing pipes for underlying defects, and prepare a totally clean surface for the new structural barriers.

To build a wet zone that lasts for decades, you cannot rely on tile grout to stop water. The underlying waterproofing barrier must handle all building shifting and daily thermal movement without tearing. Every single element, from floor drainage puddle flanges to wall intersections, must be perfectly detailed and certified.
