I didn't know they came for bathwater! (I only have a bathtub, no shower, though this is not a hardship as it's also a clawfoot bath.)

And I've had a humidifier, but it's been not working as well as it should, so am going to go invest in a new one. (The current one is cold mist, and I think warm mist really makes a difference for me.)

The overall house humidity doesn't seem to be unreasonably low (based on amount of static cat and hair are producing), however - but my skin's dry like it were a lot lower.
