Plan usable space, ventilation and wet-area details before changing a bathroom.
Safety first
Electrical, plumbing, structural and waterproofing work may require permits and qualified trades. Do not treat tile or grout alone as a waterproofing system.
Checklist
List accessibility needs and current layout problems.
Check door, fixture and circulation conflicts using the proposed layout.
Confirm exhaust air is discharged outdoors rather than into the attic.
Record leaks, loose tiles, staining and soft flooring.
Identify the proposed shower or tub waterproofing system.
Check compatibility between drains, waterproofing and finish materials.
Ask which permits, inspections and qualified trades are required locally.
Plan temporary bathroom access and dust containment during work.
Keep waterproofing, ventilation and fixture maintenance instructions.
