Quick Answer
Who this page is for: Homeowners wanting to prevent water damage in the cabinet directly under the sink.
This guide covers routine leak checks and material details to confirm for the area below a sink. A cabinet or liner should not be treated as waterproof unless its product documentation says so.
Material Standard
Caramella's standard cabinet carcass material is ENF plywood unless another material is agreed for the project, with PUR edge sealing.
Check for water before it causes damage
Leaks, splashes and wet items stored in the cabinet can affect cabinetry. Inspect the plumbing and cabinet surfaces periodically, dry spills, and contact a qualified plumbing professional if you suspect a leak. The extent of any damage depends on the source and duration of water exposure and the specified materials.
Vigilant Maintenance (DIY Defense)
These simple checks can help you notice water problems early; follow the product care instructions and get plumbing issues repaired promptly:
- Use a suitable drip tray if needed: Check product dimensions and care notes before placing a tray in the cabinet. A tray is not a substitute for finding and repairing a leak.
- Inspect plumbing connections: Look for dampness around the trap and water lines. If you see a leak, ask a qualified plumbing professional to assess and repair it.
- Dry the cabinet: Remove wet items and follow the material maker's cleaning and drying instructions after a spill.
Cabinetry specification and care
Cabinetry around a sink should be planned with the sink, plumbing, access panels, and service clearances in mind. Caramella's standard cabinet carcass material is ENF plywood unless another material is agreed for the project, with PUR edge sealing. These details do not make a cabinet waterproof; record the selected materials and scope in the quotation.
