You may be in the fortunate position in the window of your bathroom is not overlooked. And you can be very happy to leave it exactly as is, without shades or bathroom window curtains. You may not want to spend much on the window of your bathroom, or just want a simple effect. One solution for bathroom window curtains is to use a translucent material, such as lace, muslin, voile or net. These can be hung from a pole, single rod or rail. You can also use tension rods, which are easy to fix inside a hollow (no screws needed). The fabric has a slot at the top and the bar slides in it. However, remember that these tissues allow people to see when you have the light at night.
Another option for bathroom window curtains is to use cafe curtains, where it attaches a pole in the middle of the window and the curtains hanging around here or slot. This suits some situations but not in others. You can also set a number of glass shelves under the window, and place different objects in them, such as glass ornaments or plants. This provides a degree of privacy.
