Bathroom sink cabinet with oak wood countertop

A small bathroom required a small bathroom sink cabinet. We will show how to make a simple, but modern cabinet, with oak wood sink counter top and oak mouldings. The wooden mouldings were needed because they have to hide the spaces between the cabinet and the walls. The walls were not square, so we needed to create a design that would cover the gaps.
We divided the project into three sections:
- the bathroom sink cabinet
- the oak wood counter top
- the oak wood mouldings
The bathroom sink cabinet
1. We measured the space between the two walls and because we found that there were some differences from one end to the other, we took a 2-3 cm margin when we determined the dimensions of the cabinet.
2. We cut the MDF boards at the required dimensions: one board for the base of the cabinet, and two custom boards for the sides. The shape was cut as in the pictures because we have to hide the piping.

3. We drilled three holes (8 mm diameter) to be able to make the joints between the base and the sides with 8 mm wooden dowels. We used water based adhesive. It is very good for gluing MDF pieces.

4. We’ve cut two narrow MDF strips at a length equal to the distance between the two sides. They were used to give stability and strength to the cabinet. We screwed them together at 90 degrees. Then we screwed them inside the cabinet, in order to hold them until we drilled the holes for the dowels.

5. We glued up the wooden dowels and we drilled the holes for additional screws. It is very important to drill holes in MDF boards before using screws, otherwise the MDF will mostly crack.

6. We countersunk the holes with a countersink drill bit. After this, we fitted all the screws. We deepened the holes in order to be able to cover the heads of the screws with wood putty.

7. When everything was assembled, we sanded the wood putty, the dowels and all the MDF edges. We also sanded with 120 grit sandpaper, by hand, all the sharp edges.

8. We cut some MDF strips for the drawers edges, the boards for the bottoms and the boards for the drawer fronts. The drawers have a depth half of the depth of the cabinet to be able to hide the pipe system. We also sanded the edges and all the sharp corners with 120 grit sandpaper.


9. We applied a layer of special polyurethane primer for MDF.
10. After the primer dried we sanded every surface with 320 grit sandpaper.
11. After sanding, we removed the dust and applied the white polyurethane paint.


The oak wood counter top
1. We have build the oak wood counter top as usually, using our custom 4-way panel clamps. By the way you can find the free plans of the panel clamps on our blog.
2. We straightened it, cut at the required size and sanded it like we do with any other countertop.
3. We mixed different colors of wood stain to obtain the color we needed, the one you can see in the picture below.

4. After staining we applied polyurethane primer and varnish, sanding it with 320 grit sandpaper between each layer.

5. We cut the counter top so we can install the sink as in the manufacturer’s instructions.
The oak wood mouldings
1. We took a 2 by 2 cm oak wood strip. The width was chosen in order to hide the spaces up the wall.
2. We cut it at 45 degrees in length and sanded the cut surface. Then we just slightly rounded the sharp edges.
3. We stained it with the same color as the counter top, and we applied the polyurethane primer and varnish.

Finally we installed the tandem slides with total extraction for the drawers.
