So, first we select the board from which we will make the shelf. The board must be taken dry and without significant defects. It is desirable that it be smooth and not have transverse, longitudinal or combined deformation. Considering the relatively small size of the shelf, finding such a board will not be difficult.
Next, using a thicknessing machine, we adjust the thickness of the boards to 20 mm, although if desired, this size can be either increased or decreased.
Next, we use a miter saw to trim the board into the blanks we need for the future shelf.
In the end, we should end up with two pieces 76 cm long and four pieces 46 mm long.
The dimensions are relative and may vary depending on the intended location of the shelf. The width of the blanks is also chosen arbitrarily, based on your own needs and the availability of a particular board. In this case, the width is 10cm.
Next, on two blanks 76 cm long, you need to make certain marks with a pencil in the places where you plan to place the shelves.
In this case, the distance between the top and middle shelves is 21 cm (taking into account the thickness of the shelves themselves - 2 cm), the distance of the bottom shelf is 28 cm.
Now we begin grinding with a special grinding machine using a grinding wheel with a grain size of no more than 150 units. This must be done even if you have perfectly sharp knives on the surface planer and they do not leave grooves. Next, you need to repair the existing defects with wood putty (the color of the putty should match the type of wood), wait until it dries, and sand again.
Now we proceed to assembly using furniture screws or wood screws according to the previously marked marks. There shouldn't be any difficulties here. Furniture screws have a more aesthetic appearance than wood screws. Although the latter can be puttied and thereby hide their presence.
As a result, we get a finished shelf for the bathroom
All that remains is to fasten the fasteners to the back and open this shelf first with stain and then with varnish. Moreover, the varnish must be applied in three layers, and after each layer it must be sanded with fine-grained sandpaper (it is better to do this by hand). That's it, the shelf is ready!
