I installed this film...several times! It is a sturdy product with a minor flaw.  Moisture tends to make it release, so not a perfect choice for baths. It looks great, provides excellent light, & privacy.  I put in my bath and it did fall, but simple solution is add tiny amount of silicon sealer to edge to prevent moisture from loosening.

Pros: It is a heavy film, allowing full light but maximum privacy.
Cons: Moisture or condensation on windows will allow it to loosen.
