Renovating my older house created some awkward situations that these frosted doors improve very nicely.  A new bathroom opens into the living room; the frosting is sufficiently opaque for privacy, yet allow light from the west-facing bathroom window into the living space.  The second closes off the new entry/laundry from the dining room.  Both are on the same wall, about 15' apart, so the consistent look is nice.  Mounted one as a pocket door, the other as barn-style slider and they work very well.
