Installing a bathroom vanity yourself can feel like a big project. But with the right steps and a bit of patience, it’s totally doable. I’ve walked through this process many times, and I’m here to share a simple, clear guide to help you install your new vanity with confidence. Whether you’re upgrading your bathroom or replacing an old vanity, this guide will make the task manageable and even enjoyable.
Getting Ready: Your DIY Bathroom Vanity Guide
Before you start, preparation is key. Gather all your tools and materials to avoid interruptions. Here’s what you’ll typically need:
New bathroom vanity (make sure it fits your space)
Adjustable wrench
Screwdriver (Phillips and flathead)
Drill with bits
Level
Tape measure
Silicone caulk and caulking gun
Plumber’s putty
Pipe wrench
Safety glasses and gloves
Measure your bathroom space carefully. Check the width, depth, and height where the vanity will go. Also, note the location of plumbing pipes and electrical outlets. This helps you avoid surprises during installation.
Next, turn off the water supply to your sink. This is crucial to prevent leaks or water damage. Drain the pipes by opening the faucet and letting any remaining water flow out.
If you’re removing an old vanity, disconnect the plumbing carefully. Use a bucket to catch water from the drain and supply lines. Remove the vanity by unscrewing it from the wall and lifting it out.

Step-by-Step DIY Bathroom Vanity Installation
Now that you’re ready, let’s dive into the installation process. Follow these steps for a smooth experience:
Prepare the Area
Clean the floor and wall where the vanity will sit. Check for any damage or mold and fix it before proceeding.
Assemble the Vanity
Some vanities come pre-assembled, but others require you to put parts together. Follow the manufacturer’s instructions carefully. Make sure all screws and fittings are tight.
Position the Vanity
Move the vanity into place. Use a level to ensure it sits flat and straight. Adjust with shims if necessary.
Secure the Vanity to the Wall
Find the wall studs using a stud finder. Drill pilot holes through the vanity back panel into the studs. Use long screws to secure the vanity firmly.
Connect the Plumbing
Attach the faucet and drain assembly to the sink. Use plumber’s putty to seal the drain. Connect the water supply lines to the faucet and tighten with a wrench. Reconnect the drain pipe.
Seal the Edges
Apply silicone caulk around the edges where the vanity meets the wall and floor. This prevents water from seeping behind the vanity.
Final Checks
Turn the water supply back on and check for leaks. Tighten any connections if needed. Clean up your workspace.

What to Put Under a Bathroom Vanity?
Choosing what to put under your bathroom vanity depends on your needs and the vanity style. Here are some practical options:
Storage Baskets or Bins
Great for organizing toiletries, cleaning supplies, or extra towels. Choose waterproof or plastic-lined baskets to avoid moisture damage.
Pull-Out Drawers or Shelves
If your vanity has open space underneath, adding pull-out drawers can maximize storage and keep items accessible.
Decorative Boxes
Use decorative boxes to hide clutter while adding style to your bathroom.
Cleaning Supplies
Store items like toilet cleaner, brushes, and extra soap under the vanity for easy access.
Extra Toilet Paper
Keep a few rolls handy but out of sight.
Make sure whatever you place under the vanity is easy to clean around and won’t block plumbing access.
Tips for a Smooth DIY Bathroom Vanity Installation
Here are some tips I’ve learned that make the process easier and more enjoyable:
Take Your Time
Rushing can lead to mistakes. Work steadily and double-check measurements.
Use a Helper
Vanities can be heavy and awkward. Having someone assist you can prevent accidents.
Protect Your Floor
Lay down a drop cloth or cardboard to avoid scratches.
Label Parts
When assembling, keep screws and small parts organized and labeled.
Check Local Codes
Some areas have plumbing or electrical codes. Make sure your installation complies.
Test Before Final Sealing
Turn on water and check for leaks before applying caulk.
Keep Instructions Handy
Follow the manufacturer’s guide closely for your specific vanity model.
Enhancing Your Bathroom with the Right Vanity
Choosing the right vanity can transform your bathroom’s look and function. Here are some factors to consider:
Size and Fit
Measure carefully to ensure the vanity fits well without crowding the space.
Style
From modern to rustic, pick a vanity that matches your bathroom’s decor.
Material
Look for moisture-resistant materials like solid wood with a waterproof finish or MDF with laminate.
Storage Needs
Consider how much storage you need. Drawers, cabinets, and open shelves all serve different purposes.
Countertop Options
Granite, quartz, marble, or laminate countertops each have pros and cons in durability and maintenance.
Sink Type
Choose between undermount, vessel, or integrated sinks based on your style and cleaning preferences.
By selecting the right vanity and installing it yourself, you save money and gain a sense of accomplishment.
