Your project will begin with you removing the current setup. To do this safely, you must turn off the water. To be extra secure, you can turn the water off to your home. This will be a hose in your basement. Otherwise, you can simply turn off the water valves to your sink.

Near the valve for the water, there will be a drainpipe. It will curve into the wall. Technicians call this the “P-trap.” Get a pail or bucket to catch any water as you disconnect. From there, loosen and pull the trap. It will disconnect from the drainpipe. 

After this, disconnect the water lines. Be prepared for any spillage of water. 

3. Remove vanity

Once preparation is complete, push your vanity into the correct position. It should sit flush with the marks you’ve made previously. Ensure that the vanity is sitting level and isn’t wobbly. If there is any unbalance, use shims. 

Once your vanity looks good and is level, begin to install. To do this, you’ll attach your vanity to the wall with screws. Try to drill into existing studs. If you don’t have studs, use wall anchors. 

7. Add countertop

Tips for Choosing the Right Bathroom Vanity

The countertop will completely transform the look! Once your vanity is secured, place the pre-cut countertop. Make sure it lines up perfectly. To secure, use caulk. Caulk or sealant should be used to secure the top to the base. Also, use caulk where the top meets the backsplash. 

8. Install faucets

Finishing Touches 

Your new vanity looks great! Don’t forget to add finishing touches. There are simply decor and touches you can add to finish off the look. Determine whether your bathroom needs other upgrades. For example, does your new faucet match the finish on other bathroom fixtures? Some of our favorite things to consider are:

  • Mirror. Does the mirror over your vanity match the aesthetic of your new vanity? Consider adding a new mirror. Round mirrors have been very popular lately. 
  • Towel holders. Do your towel holders complement your new vanity? If not, consider new ones. Make sure hand towels are in reach. 
  • Toilet paper holders. This small detail is often overlooked. However, the finish should match your faucets. If not, consider buying a new holder. 
  • Mats. Bath mats are a simple addition, but they make a big impact. Buy new bath mats for an entirely new experience! Choose from different colors, textures, and sizes. This is a cheap way to elevate the look of your bathroom. 
  • Other faucets. Consider other faucets in your bathroom. This will include your shower faucet and bath faucet. Make sure they complement the faucets on your sink. You want everything to look cohesive.
