...I'd only suggest pulling the plants out when spikes are visible. The gases in a bathroom may cause bud loss or yellowing of the spike. I've had it happen before in two bathrooms. VERY good place to start initiating spikes, though!
In Pleurothallids, I find that the plants are too susceptible to the gases and will show a steady (if not irreversible) decline in health...
I have no idea what gases they are (besides out the 'other end'), but put a brass coin in there and somewhere else in the house, and see the brass coin tarnish like no other! Sometimes, it may just take a certain day... maybe it's all just a Florida thing?
