The fifth edition of NKBA's Kitchen & Bath Planning Guidelines with Support Space and Accessibility is the premier publication for Certified Kitchen and Bath Designers (CKBDs) and Certified Master Kitchen and Bath Designers (CMKBDs) working across both borders in the planning and design of kitchens, baths, and ancillary spaces. This comprehensive 5th edition has been prompted by the release of key code documents, specifically the 2024 International Residential Code (IRC) and the CSA B652 Accessible Dwellings 2023 (Canada). Subject Matter Experts (SMEs) meticulously assessed the IRC against the latest National Building Code of Canada, achieving uniformity in kitchen and bath planning guidelines.
