Frosting the glass on your bathroom window is a good way to obtain privacy without losing light. There are a few different methods for doing this. Putting frosted film on is easiest, followed by acid etching then sandblasting. For acid etching and sandblasting, you may need to remove the window to apply the treatment. Sandblasting requires special equipment and some practice for an even texture. Frosted film is the only method that can be removed, though it can be a difficult process getting it on.

    Frosted Film

  1. 1

    Use scissors or a utility knife to cut the film to fit the glass portion of your bathroom window.

  2. 2

    Clean the glass thoroughly with either a squeegee or a lint-free cloth.

  3. 3

    Apply the film to the window following the instructions provided with the film. This may require applying the film to one edge of the window then removing the backing as you apply it over the window in small sections. Or it may involve using a small amount of dish soap in a spray bottle and the squeegee.

    Acid Etching

  1. 1

    Remove the window from its frame. You do not need to remove the glass from the frame. Since you will wash the etching cream off the glass, do this project where the acid in the etching cream will not cause damage.

  2. 2

    Apply contact paper to all areas of the window that you do not want frosted, including the frame and any part of the glass.

  3. 3

    Using a brush meant for use with etching cream, apply the cream to the glass and leave it on as long as recommended by the manufacturer.

  4. 4

    Remove the etching cream using the method recommended by the manufacturer.

  5. 5

    Clean the window thoroughly to wash off all the etching cream.

  6. 6

    Replace the window in the frame.


  1. 1

    Remove your bathroom window from its frame.

  2. 2

    Place contact paper on your bathroom window frame and any parts of the glass you do not want frosted.

  3. 3

    Spray the glass using the sandblasting equipment and with the window in a sandblasting cabinet. An even frosted effect can be difficult to achieve if you do not have experience with the technique, so consider practicing on other glass first.

  4. 4

    Clean your window and make sure that the frosting is even and meets your privacy needs.

  5. 5

    Replace your bathroom window in the frame.

Tips and warnings

  • Wear protective clothing and goggles when doing acid etching or sandblasting.
  • Do not use hydrofluoric acid to etch your bathroom glass unless you have extensive training on how to handle this substance, because it is very dangerous. It also must be disposed of at a waste site designated for hazardous materials.
