How to Make a Wooden Floating Vanity with a Concrete Countertop
Creating a wooden floating vanity with a concrete countertop is an excellent way to add a modern, stylish, and functional piece to your bathroom or powder room. The combination of warm wood with the industrial look of concrete brings a unique aesthetic to any space. This project requires some woodworking skills, attention to detail, and an understanding of both wood and concrete. Here’s a step-by-step guide to help you make your own wooden floating vanity with a concrete countertop.
Materials and Tools
For the Floating Vanity:
- Plywood or hardwood boards (depending on your design)
- Wood screws
- Wood glue
- Cabinet hinges (if you plan on adding doors)
- Drawer slides (if you plan on adding drawers)
- Sandpaper (various grits)
- Wood finish or stain (optional)
For the Concrete Countertop:
- Quick-setting concrete mix
- Concrete bonding adhesive
- Mold (typically made of melamine or MDF)
- Plastic sheeting (for the mold base)
- Concrete sealer
- Trowel
- Rubber gloves and safety goggles
- Mixing container
Tools:
- Power drill
- Circular saw or table saw
- Level
- Measuring tape
- Jigsaw (if needed)
- Concrete mixer or large bucket
- Trowel and smoothing tools
- Screws and anchors (for mounting)
Step 1: Design and Plan the Vanity
The first step in this project is to create a detailed design for your floating vanity. Decide on the dimensions, the type of wood you’ll use, and the style of the cabinet (open shelving, doors, or drawers). For a clean look, a simple rectangular design works well, but you can incorporate unique details, like beveled edges or inlays, to give it personality.
Plan the length, depth, and height of the vanity to fit your bathroom space. Typical bathroom vanities are around 32 to 36 inches tall, but adjust based on your personal preferences. The width should accommodate the sink and any plumbing underneath.
Step 2: Build the Wooden Vanity
Cutting the Pieces: Using plywood or hardwood, cut out the main components of your vanity frame. You’ll need:
- Two side panels (usually the height of the vanity)
- A bottom panel (the length of the vanity)
- A back panel (optional, but it adds stability)
- Support beams or brackets (for the floating design)
Assembly: Assemble the frame using wood glue and screws for a secure bond. Make sure the vanity is square by using a level to check the edges. If you’re incorporating doors or drawers, you can add the necessary components for the cabinetry.
Sanding and Finishing: Sand the entire structure with a medium-grit sandpaper and finish it with a wood stain or paint of your choice. Seal it with a polyurethane finish for durability and protection from moisture.
Step 3: Prepare the Concrete Countertop Mold
Concrete countertops are often poured in a mold that reflects the desired shape and size. You can make your own mold out of melamine boards, MDF, or plywood. To ensure smooth edges and easy removal, line the mold with plastic sheeting or mold release spray.
To create the mold:
- Measure the dimensions of your vanity and cut the mold pieces to fit.
- Assemble the mold by securing the edges with screws.
- Ensure the mold is level and square to avoid any issues when pouring the concrete.
Step 4: Mix and Pour the Concrete
Mixing the Concrete: Follow the instructions on your concrete mix bag, usually combining the dry mix with water in a large bucket or concrete mixer. For a smooth, high-quality finish, ensure the consistency is like thick pancake batter.
Pouring the Concrete: Once the concrete is mixed, pour it into the mold. Use a trowel or putty knife to spread it evenly and eliminate any air bubbles. For added strength and to prevent cracking, you can insert a layer of reinforcing mesh or rebar into the mix. Make sure to smooth the surface as you go along.
Leveling: After pouring, use a level to ensure the surface is even and flat. If you want a specific finish (like a smooth or slightly textured top), use a trowel or smoothing tool to achieve your desired look.
Curing: Let the concrete cure for at least 24-48 hours. Concrete should be kept moist during curing to avoid cracks. You can cover the surface with plastic sheeting and spray it with water every few hours.
Step 5: Remove the Mold and Finishing Touches
Once the concrete has set and hardened, carefully remove the mold. If you used plastic sheeting, it should come off easily. Sand any rough edges with a fine-grit sandpaper and use a concrete grinder for a perfectly smooth surface.
Sealing the Concrete: Concrete is porous, so sealing it is crucial to prevent stains and water damage. Apply a concrete sealer to the surface according to the manufacturer’s instructions. This will protect the countertop and give it a polished finish.
Step 6: Mount the Floating Vanity
To mount the floating vanity, you’ll need to secure the vanity frame to the wall with strong brackets or a floating mounting system. Use a level to ensure the vanity is perfectly straight. Drill holes into the studs of your wall, insert heavy-duty anchors or screws, and securely fasten the vanity to the wall.
Once the frame is mounted, carefully place the concrete countertop on top. Depending on the weight and your design, you may need assistance to lift and position the concrete piece. Make sure it’s centered and stable.
Step 7: Install Plumbing and Accessories
After securing the countertop, install your sink, faucet, and any other plumbing elements. Make sure the plumbing fixtures align correctly with the holes in the concrete countertop. If needed, use a diamond drill bit to make any additional holes for faucets or drains.
Finish the vanity by adding any shelves or accessories that you’ve planned. For example, you might want to install a mirror, lighting, or a towel rack above the vanity for functionality.
Final Touches
Once the vanity is installed and the plumbing is connected, take a step back and admire your work. The combination of wood and concrete gives your bathroom a sleek, modern look that’s sure to impress.
Tips for Success:
- Use a concrete mix with a lower shrinkage rate to avoid cracks.
- Be patient with the curing process—rushing could compromise the strength of the countertop.
- Consider adding a backsplash or edge trim for extra polish.
By following these steps, you’ll create a stunning and durable wooden floating vanity with a concrete countertop that adds both functionality and aesthetic value to your bathroom.
