Tips

  • Leave enough space between the bottom shelf and the toilet for access.
  • It's easier to install shelves from the top down.

Common Mistakes to Avoid

1. Incorrect Measurements

Reason: Taking inaccurate measurements of the toilet and available space leads to a cabinet that doesn't fit properly or looks awkward.
Solution: Carefully measure the toilet's dimensions and the available wall space multiple times before starting construction.

2. Poorly Secured Cabinet to the Wall

Reason: Using insufficient or inappropriate fasteners can result in a wobbly or unstable cabinet, potentially leading to damage or injury.
Solution: Use heavy-duty wall anchors appropriate for your wall type and distribute weight evenly with multiple fasteners.

3. Ignoring Plumbing Access

Reason: Building a cabinet that completely obstructs access to the toilet's plumbing creates future maintenance headaches.
Solution: Leave sufficient space and/or build access panels into the cabinet design to allow for easy access to the plumbing.

FAQs

What tools and materials will I need to build this cabinet?
The necessary materials depend on your design, but generally include wood (plywood or MDF), wood glue, screws, hinges, a door handle, paint or stain, measuring tape, saw (circular saw or hand saw), drill, screwdriver, sander, and possibly a router for decorative edges. A complete list will be provided in the materials section.
How do I ensure the cabinet fits perfectly over my toilet?
Before building, carefully measure the width and depth of your toilet and the available wall space above it. Account for any toilet tank protrusions or wall irregularities. Building a slightly smaller cabinet initially allows for adjustments during installation.
What if I don't have much woodworking experience? Is this project still doable?
Absolutely! This guide is designed for beginners. While some woodworking skills are helpful, the steps are explained clearly and are achievable with patience and careful attention to detail. Don't be afraid to take your time and ask for help if needed.
