Kitchens and bathrooms destroy the wrong plywood. Steam and standing humidity swell an MR-grade sheet within a couple of years. Here's how to choose boards that survive a decade.
1. Go BWP / marine
For wet zones, skip MR and even BWR — use BWP (marine, IS:710). The extra ~20–40% over BWR is small next to redoing a swollen kitchen.
2. Right thickness
| Application | Thickness |
|---|---|
| Carcass / base units | 18 mm |
| Shutters | 18 mm |
| Back panels | 6–12 mm |
| Shelves | 12–18 mm |
3. Demand the certification
Look for the IS:710 stamp, a clear brand and a written warranty — your only real guarantees in a ~70% unbranded market.
4. Consider WPC for the wettest spots
Under the sink or in splash-prone bathroom cabinets, a WPC board is even safer than marine ply.
