The overall scope depends on what’s being replaced, what needs repair behind the wall, and whether plumbing locations change. Material choice (tile, acrylic, or waterproof panels) also affects the workflow and maintenance expectations.
| Factor | Why it matters |
|---|---|
| Existing conditions | Moisture damage, framing issues, or subfloor repairs add steps |
| Plumbing changes | Moving valves/drains can affect layout and accessibility |
| Wall system | Tile requires membranes + grout; panels reduce grout dependence |
| Glass and enclosure | Different enclosure types change measurements, install steps, and maintenance |
| Accessories | Niches, shelves, benches, and grab bars require planning and blocking |
