1Water first, looks second
Showers and tub surrounds depend on layers you cannot see: backer board, waterproofing membranes and proper slopes. When comparing estimates, ask how the shower area is waterproofed and what the product is.
2Ventilation
A bath fan moves humid air outside. Ask whether the fan is sized for the room, whether it vents outdoors rather than into an attic, and whether a new one is part of the scope.
3Fixtures and finishes
| Item | Things to consider |
|---|---|
| Tile | Slip resistance, grout upkeep, and whether it is rated for wet areas. |
| Vanity and sink | Storage, clearances, and the plumbing already in the wall. |
| Faucets and shower valves | Compatibility with existing pipes and the warranty offered. |
| Lighting | Wet-location ratings and light near the mirror. |
| Floors | Water resistance and how the edges are sealed. |
4When a refresh becomes a remodel
Moving a toilet, tub or shower drain, or opening walls, usually means more plumbing and electrical work and often a permit. Ask your local building department what applies before you set a budget.
5Questions worth asking
- What will you do if the subfloor or wall is damaged underneath?
- Who removes old materials?
- How long will the bathroom be out of use?
