Make sure the mark is level and centred in the space where you want to install the unit.

Tips for a Successful Vanity Unit Installation

Here we share some expert tips to help you ensure a successful vanity unit installation process.

  1. Measure Twice, and Cut Once!
    If you need to make any cuts or adjustments to the bathroom vanity unit, then double-check your measurements to ensure that everything fits perfectly. 
  2. Use the Right Tools
    DIY vanity installation will require knowledge and experience in using various plumbing tools. Use of the wrong tool or technique may be damaging to the vanity unit. 
  3. Follow the Manufacturer's Instructions
    Always read and follow the manufacturer's instructions for installation. This will ensure the correct and smooth installation of the vanity unit.
  4. Check for Levelness
    Use the spirit level to ensure that the vanity is levelled horizontally and vertically. This is critical for ensuring proper functionality and preventing water damage. 
  5. Allow Proper Ventilation
    Although vanity units have moist-resistant material, continuous exposure to higher humidity levels can lead to mould and mildew growth. Therefore, it is important to ensure adequate ventilation in the bathroom to prevent damage.
  6. Use a Silicone Sealant
    Apply a bead of silicone sealant around the edges of the vanity unit to create a waterproof seal and prevent water damage.

Vanity Unit Maintenance and Care

Cleaning and maintenance are important to ensure the longevity of your vanity unit and to preserve its look. Here are a few bathroom vanity installation tips to use when caring for your unit. 

  1. Regular Cleaning: Clean the vanity unit surface with mild detergent a couple of times a week. To prevent scratches, never use an abrasive cleaner. If stains are tough, consider using an effective non-abrasive cleaner. 
  2. Avoid Harsh Chemicals: Make sure you don't use harsh chemicals or bleach on your vanity unit. These chemicals can cause discolouration and damage to the surface of the unit
  3. Wipe Up Spills Immediately: Stains should be cleaned up immediately after spills to prevent them from setting in. Use a soft cloth and mild detergent to clean up spills.
  4. Avoid Scratching the Surface: Vanity units are vulnerable to scratches if you use abrasive sponges or brushes. Therefore, use a soft cloth or non-abrasive sponge instead.
  5. Proper Drain Maintenance: To prevent clogs and blockages, regularly clean and maintain the drain on your vanity unit. You can use a drain cleaner or plunger to remove any debris or buildup in the drain.
  6. Regular Inspection: Be sure to inspect your vanity unit for any signs of damage or wear and tear regularly. Any issues should be addressed promptly to avoid possible damage.

Following these guidelines for maintaining and caring for your vanity unit can ensure its longevity and preserve its appearance.

Troubleshooting Common Vanity Unit Installation Issues

DIY installation can be challenging for someone who is not familiar with basic plumbing. Here we have discussed a few common issues that may arise during bathroom cabinet installation and some solutions to help you overcome them.

  • Uneven Floors
    An uneven floor can cause the vanity unit to wobble or tilt. This problem can be solved by adding shims to the unit. These are small pieces of wood or plastic that you can place under the legs of the floor-standing vanity unit to level it.
  • Plumbing Problems
    Plumbing problems are one of the most common challenges during vanity installations. It can be difficult to connect the water supply and drain properly if you are not familiar with plumbing work. Therefore, you may want to hire a professional plumber to assist you with this aspect of the installation.
  • Incorrect Measurements
    It is possible to run into a lot of problems during the installation of vanity units if measurements are incorrect. Therefore, you should measure the space accurately before installing the vanity unit. In addition, don’t forget to take into account any obstructions, such as pipes and electrical wires.
  • Wall Anchors
    If you are installing a wall-mounted vanity unit, wall anchors are necessary to secure them to the wall. You must follow the manufacturer's instructions carefully and choose the right size and type of wall anchors to use with your vanity unit.
  • Cabinet Doors and Drawers Not Closing Properly
    If your vanity unit's cabinet doors or drawers don't close properly, the unit may be unlevel, or the hardware may not be installed correctly. You can resolve this issue by checking the level of the unit and adjusting the hardware as necessary.

We have discussed the common challenges that may arise during a vanity unit installation. However, if you encounter any issues that you are unable to fix on your own, don’t hesitate to consult with a professional plumber.
