Not every single part of your kitchen needs top-grade plywood. But the parts that do? If you compromise there, the kitchen starts aging fast. Here’s a practical checklist—zone by zone. First, a quick rule BWP is for zones that face water/steam consistently. BWR/MR can work for dry zones if the build and sealing are excellent—but kitchens rarely remain “dry”. Also: your own blog already explains plywood types; this post is about where to use what, in real kitchens.
Zone 1: Sink Unit (must be BWP) Why
daily water splash plumbing leaks wet utensils cleaning chemicals What to build with BWP base panel side panels near plumbing back panel (especially if wall is damp-prone) Extra precautions (non-negotiable) seal all cut-outs raise base off floor (skirting/legs) avoid raw edges
Zone 2: Hob Unit (strongly recommended BWP) Why?
Not water—but heat + steam + oil. The area around the hob is a pressure cooker environment. What should be BWP here side panels near the hob drawer boxes if they’re close to heat/steam source any vertical panel receiving steam from cooking
Zone 3: Dishwasher / Washing Machine cabinet (BWP) Why?
These machines create moisture internally and often leak subtly. If you have any appliance that uses water, treat it like sink zone.
Zone 4: Overhead Cabinets (depends, but be careful)
Many people assume overhead cabinets are dry. They’re not.
They face: steam rising daily warmth from cooking grease particles Recommendation If your kitchen is used heavily: BWP If light use + chimney works well + sealing is done: you can consider BWR, but BWP is safer.
Zone 5: Pantry Tall Unit (BWR or BWP, based on location)
If pantry is near window/balcony/bathroom wall—use BWP. If it’s deep inside a dry zone—BWR can work.
Zone 6: Lofts (BWR is okay, but…)
Lofts are often ignored, but they face: humidity accumulation near ceiling poor ventilation long-term storage weight Recommendation BWR can be okay Ensure thicker board + strong support Seal edges properly
7. How to Ensure You’re Getting Real Waterproof Plywood
Before buying, check for:
✔ ISI Mark
✔ IS 710 Printed on the sheet
✔ Manufacturer’s license number
✔ Consistent thickness (calibrated preferred)
✔ No visible core gaps
✔ Uniform veneer quality
✔ Strong smell of phenolic resin (many real BWP sheets have it)
