Why Is Floating Bathroom Vanity Important?

A floating bathroom vanity offers a number of advantages to homeowners. It helps keep the floor free from clutter and gives the room a modern, open feel. Additionally, it can help make the bathroom look larger by freeing up space. Furthermore, it’s easier to clean under and around because there are no hard-to-reach areas underneath the vanity.

Finally, a floating vanity is especially convenient for those with limited space in the bathroom. While traditional vanities require additional floor space to accommodate them, a floating vanity can be easily installed without taking up too much room. With its minimalist design and versatility, a floating bathroom vanity can be the perfect solution for any bathroom.

No matter what type of bathroom you have, floating vanities provide a great option for those wanting to create an updated, modern look.

From adding storage space to opening up the room, there are countless benefits that come with having a floating vanity in your home. With its sleek design and appeal, it can be the perfect piece to tie together any style of bathroom.

While it may be a bit more effort to install, the result of having a floating vanity can be well worth it. Floating vanities are an ideal choice for many homeowners looking to make their bathrooms look modern and sleek. With its versatility and convenience, they offer homeowners the perfect solution for any bathroom.

Plus, the updated look can help give any bathroom a modern touch. With the right materials and installation, a floating vanity can be an easy way to update your bathroom into something more modern and stylish.

Wood is a Popular Choice

What Is the Best Material for Floating Vanity?

When it comes to choosing the best material for a floating vanity, you should consider both form and function. Wood is a popular choice because of its natural aesthetic, but it may not be the most durable. Metal is also an option, but it often requires more upkeep to maintain its luster.

For a modern look that’s easy to care for and won’t break the bank, materials such as laminate or melamine are great options. Laminate is resistant to water damage and comes in many colors and styles. Melamine has a glossy finish that can be wiped down easily and resists moisture well. Both materials are relatively inexpensive compared to other vanity options, making them ideal for budget-conscious homeowners.

If you’re looking for something more luxurious, engineered quartz or marble might be your best bet. These materials provide a higher-end look along with durability that’s on par with natural stone. However, these materials are significantly more expensive and require regular sealing to ensure their longevity.

10 Methods How to Build a Floating Bathroom Vanity

1. Determine the Size of Your Vanity. 

The first step is to determine the size of the vanity you want to build. You will need to take into account the size of your bathroom, as well as the number of sinks you want. If you have a large bathroom, you may want to consider a double sink vanity. 

If you have a smaller bathroom, you may want to opt for a single-sink vanity. To get an idea of the dimensions you need, measure the area where you want to place your vanity. Try to leave at least 18 inches of space between the vanity and any walls or other fixtures.

2. Choose the Material for Your Vanity. 

Once you have determined the size of your vanity, you will need to choose the material. You can use a variety of materials, such as wood, metal, or even glass. If you are using wood, make sure it is sturdy enough to support the weight of your sinks and countertop. 

For a more modern look, metal or glass might be the best option. Make sure that whatever material you choose is suitable for use in a bathroom environment, as it should be able to withstand moisture and humidity.

3. Cut the Lumber for Your Frame. 

Once you have chosen the material for your frame, you will need to cut the lumber to size. If you are using a saw, be very careful and use clamps to hold the pieces in place while you cut them. If you are using a router, clamp the boards and use extreme caution with your router bit. 

When cutting the lumber for your frame, remember to add a few inches to the length and width of each piece to account for any discrepancies in your measurements. While cutting the lumber, make sure to wear protective goggles and a dust mask.

4. Assemble the Frame of Your Vanity. 

Once all of the pieces are cut to size, it is time to assemble the frame of your vanity. If you are using screws, make sure they are long enough to go through all of the layers of wood. You may also want to use glue or brackets to reinforce the joints. 

If you are using a purchased vanity base, make sure to follow the manufacturer’s instructions. Though the material and size of your base will vary, the basic assembly steps remain the same. However, custom-built vanities require more precision and attention to detail.

5. Cut Holes for Your Sinks and Plumbing. 

The next step is to cut holes for your sinks and plumbing fixtures. Be very careful when cutting these holes, as you do not want them to be too big or too small. You can use a jigsaw, or a hole saw to make the cuts. 

Be sure to measure twice and cut once. Try to make the holes as precise and even as possible. Additionally, try to avoid making the holes too close together. This will make it more difficult for you to install your sinks and plumbing fixtures.

6. Install Your Sinks and Plumbing Fixtures. 

Once all of the holes are cut, it is time to install your sinks and plumbing fixtures. Make sure everything is properly secured before moving on to the next step. Be sure to check for any leaks or other issues before continuing on with the installation of your floating vanity. 

If all is well, you are now ready to install the countertop. However, if you are having any issues, it is important to resolve them before moving forward. Although it may be tempting to try and push through, it is important to make sure everything is properly secured and functioning as intended.

7. Attach Your Countertop.

The next step is to attach your countertop to the frame of your vanity using screws or brackets. Be sure that everything is level before proceeding any further. If you have a pre-fabricated countertop and vanity, this step may not be necessary. 

However, if you are building from scratch, it is important to ensure that everything is securely attached. While attaching the countertop, be sure to fill any gaps between the top and frame with silicone caulk. This will ensure that your vanity is watertight.

 Install Any Doors or Drawers

8. Install Your Doors and Drawers.

The next step is to install any doors or drawers that you want on your vanity. Make sure that they are properly aligned before attaching them. Once they are secure, you can add handles or knobs to the doors and drawers if desired. If you opted for a sink, make sure to install the faucet and check for any leaks. 

Once everything is secure, you can add a countertop to finish off the vanity and complete the installation. Though it may seem daunting, building a floating bathroom vanity is a simple and rewarding task that can instantly upgrade your bathroom. With the proper planning and knowledge, you can have a beautiful, one-of-a-kind vanity that is sure to be the focal point of your bathroom.

9. Add any Final Touches.

The final step is to add any final touches that you want, such as handles or knobs. Make sure that everything is securely attached before using your new vanity. You can also add a touch of decoration with plants, photos, or other knickknacks around the vanity to make it look more inviting. 

Now that your vanity is finished, you can enjoy all the benefits of a floating bathroom vanity. Not only does it look great, but you also have more storage space and easier access to all of your bathroom items. However you decide to use your new vanity, you can rest easy knowing that you created a unique piece of furniture that is sure to stand the test of time. Enjoy!

Once everything is complete, enjoy your new floating bathroom vanity. Whether you choose to show it off or have it tucked away, your floating vanity will be the perfect finishing touch for your bathroom makeover.

You can use the extra storage to keep your bathroom organized, and the contemporary style will be sure to draw compliments. Whether you choose a single basin or a double basin design, you’ll have plenty of space for all your bathroom essentials.


Taking the time to build a floating bathroom vanity is simple, yet rewarding. With some basic tools and materials, you can easily make your own unique vanity that will add style and elegance to any bathroom. Not only does it look great but it’s also affordable – you don’t have to break the bank to install a one-of-a-kind feature in your home.

A wise decision is to paint or varnish the boards for added protection from moisture and possible discoloration over time. For a cutting edge way to spruce up an otherwise dull bath area, consider constructing a custom vanity made out of wood and pipes or other metal material sources. Now that you know how to build a floating bathroom vanity, why not go ahead and give it a try?
