There are several nuances that should be taken into account immediately during repairs.
Then there will be less hassle with the bathroom, and order will always reign there with minimal effort.
Ventilation
This aspect should be considered at the very beginning, when the renovation is just being planned.

Well-thought-out ventilation will help avoid problems with airing the room, and this is the main protection against the appearance of fungus on surfaces.
Grout
White grout is considered a classic color for tiles, but it is known that over time it loses its whiteness.
A much more practical option would be gray grout.
Storage spaces
For the bathroom, it is worth looking at a large hinged mirror cabinet with a depth of 15–18 cm.
It should be installed above the sink and used to store all the cosmetic arsenal that usually creates visual noise.
Also, at the renovation stage, it is worth choosing a place where you can install a niche with shelves made of porcelain stoneware, glass or metal.
It will also allow you to successfully place all sorts of bottles, flasks and other bathroom attributes.
