Choosing the Right Bathroom Mirror Cabinet

The first step in bathroom cabinet installation is choosing the right bathroom mirror cabinet for you and your daily needs. Consider these factors.

Think about the space available in your bathroom. A wall-mounted bathroom mirror cabinet that is rectangular, round or triangular is ideal for saving space while providing ample storage.

Planning the Installation Location

Before installing your DIY bathroom mirror cabinet, plan where you’ll place it. Consider the following:

Best Height for Installing a Bathroom Mirror Cabinet

The general rule is to install the mirror at eye level, typically around 150-160cm from the floor. However, this can vary depending on the size of the user and the height of the bathroom sink.

Accessibility

Make sure the cabinet is within easy reach for everyone who will be using it. Ensure there’s enough space to open the doors or access the mirror comfortably.

Step-by-Step Guide to Installing a Bathroom Mirror Cabinet

Now, let’s walk through the process of installing your beautiful bathroom cabinet with a mirror:

1 – Mark the Wall: Use your measuring tape and pencil to mark where the bathroom mirror cabinet will be mounted. Ensure it’s level and at the correct height.

2 – Drill Holes: Drill holes into the wall where you’ve marked, making sure to drill into studs if possible. If you’re mounting the cabinet to drywall, use wall anchors to secure it properly.

3 – Attach the Mounting Brackets: Many bathroom mirror cabinet models come with mounting brackets that need to be attached to the wall first. Use screws to secure these brackets into the drilled holes.

4 – Hang the Cabinet: Once the brackets are securely in place, lift the cabinet and hook it onto the mounting brackets. Ensure the cabinet is level by using a spirit level.

5 – Secure the Cabinet: If necessary, screw the cabinet into the wall for added stability. Double-check that everything is aligned correctly.

6 – Final Checks: Open and close the doors to ensure they function smoothly. Check that the cabinet is firmly attached to the wall and that there’s no wobbling.

Common Mistakes to Avoid

While installing a bathroom mirror cabinet is a relatively straightforward process, there are a few common mistakes you should avoid:

Incorrect Height

Installing the cabinet too high or too low can make it difficult to use. Ensure it’s positioned at the right height for easy accessibility.

Not Using Wall Anchors

For heavier bathroom mirror cabinet models. wall anchors are crucial to ensure the cabinet stays securely on the wall.

Forgetting to Check for Studs

Drilling into studs provides better support. Use a stud finder to avoid drilling into weak areas or the wall.

Additional Tips for DIY Enthusiasts

Plan for Wiring
