Waterproofing and water management
A water-resistant finish and a waterproof assembly are different things. The earlier wooden-shower and floor questions depend on understanding that distinction.
Control the path of water
Identify where water arrives, how it drains, and which layer prevents entry into vulnerable materials. Connect the protective layer across transitions, corners, penetrations, and drains. Surface appearance cannot confirm that concealed work is continuous.
| Situation | Main distinction |
|---|---|
| Shower | Finish, waterproofing, slope, and drain must work together |
| Slab floor | Ground vapor control is separate from surface waterproofing |
| Roof / wall | Cladding must be coordinated with drainage and openings |
| Pool | The shell, finish, penetrations, and movement details form a specialized system |
Schluter’s shower waterproofing systems illustrate membranes, corners, and penetration seals. Those products’ tile-system details do not establish an approved wood-cladding assembly.
Wood in wet areas
Sealant or an oil finish on wood does not create a reliable waterproof shower. A decorative wood layer needs independent water containment and a way to drain and dry. Fastening must not defeat the protective system.
Inspection and testing
Schedule checks while work is visible. Verify substrate preparation, transitions, penetrations, and the relevant system’s test procedure before covering them. Plan how later maintenance reaches the drain, seals, and removable finishes.
