Context and Design Intent
- Create an easy-to-maintain, well-ventilated common bathroom with safe access and dependable water containment.
- This file is the authoritative requirements record for this area. The initial draft extracts known points from 10 - Requirements/00 - Renovation Discussion Summary.md; later merges must follow 02 - AI Collaboration Rules.md.
Non-Negotiables
- WC2-NN-001 — Replace all sanitary fittings and fixtures, renew waterproofing and inspect existing pipes.
- WC2-NN-002 — Robot-vacuum access into WC2 is not required.
- WC2-NN-005 — Use an integrated or joint-minimised sink and countertop assessed for scratch, stain and chemical resistance, repairability and warranty.
Strongly Preferred
- WC2-SP-003 — Provide useful vanity storage and accessible service boxing for maintenance and future HIP work.
- WC2-SP-004 — Improve ventilation and provide wet/dry separation where practical.
Decisions Outstanding
- WC2-DO-006 — Decide whether WC2 has one entrance or two, and whether access is from the passage, kitchen or both.
Detailed requirements and coordination
Questions for the Interior Designer
- Who will use WC2 daily and will it serve guests?
- Is wet/dry separation a priority or optional given the room size?
- What storage, shower and accessibility needs differ from WC1?
Whole-Home Coordination
- Refer to 10 - Requirements/01 - Whole-Home Systems Requirements.md for shared electrical, network, plumbing, AC, accessibility and service-access requirements.
