Could the scents be harming your birds?.... I’m not sure if they would actually harm the birds or if they just find them unpleasant.
I think it would be best if you switched to unperfumed shampoo/shower gels though, considering the birds are in the actual bathroom. There are plenty to choose from, often created for people with eczema or allergies.
I’d also make sure that you ensure that everyone switches on the extractor fan (if you have one & it’s not automatic) and leaves it running for a while afterwards. Open windows in the summer.
Alternatively, is it not possible for you to wheel the cage out of the bathroom whilst it is in use?
