Bathroom window treatments must first provide privacy of course, however they also need to be able to withstand high levels of humidity.  This section has our recommendations for bathroom window treatment ideas.  If the window is near the tub, shower or spa, you'll want a material that won't warp, crack or mildew.  Faux wood blinds and shutters made from either durable vinyl or composite wood materials are perfect in this case.  If your bathroom has good ventilation or the window is away from a water source, a non-cotton fabric treatment can provide a bright splash of color and soften the decor.

things to consider:

Balancing your needs for privacy and natural light can be tricky, but the top down/bottom up option available on many styles of window shades lets you cover the bottom part of the window while lowering the shade from the top, allowing light in and humidity out - a bathroom priority.  The slats on faux wood blinds and shutters can be tilted upwards to admit some light while maintaining privacy.

Bathroom window treatments that go over windows frequently left open are also subject to an increased need for cleaning - moisture plus airflow equals dirty window treatments.  Faux wood (vinyl) blinds are also a good choice for their ability to be easily cleaned.  While aluminum mini blinds can also be cleaned easily, they are more prone to damage than vinyl - another reason to choose vinyl bathroom window treatments.
