Mine do fine in my bathroom, even in Winter. Serpens, bella (if you have it) and polyneura would do fine, as well as carnosa, pubicalyx, obovata, diversifolia, and kerrii, off the top of my head. Just take care to not over-water.

I have all of those, lol. I might move serpens in there. It's sulking with the move and all it's nice new growing tips are dying off. I do have bella, she is currently lurking over a doorway looking like she escaped from Sideshow Bobs head. I don't think there is room in the bathroom for her.

I have an Amoena and a Diversifolia in our bathroom and they LOVE it. They have definitely responded to the constant steam/humidity. The leaves have become bigger and slightly more succulent since I moved them there.

I have several in the bathroom window. West exposure & frosted glass, the Hoyas love it. I have my Oldest Kerrii (12 yrs+) & a Pubicalyx which recently showed its first peduncle (woo hoo). The window is right next to the shower. I don't water these in here too often, maybe once every 10 days to 2 wks (when I think of it).

Thanks people! I'm now scheming up ways to move some of my plants in there. Quick question about diversifolia, I've read conflicting things about it's temp range. I only got mine about 6 months ago so I have no idea if it will survive down here in the cold. It's not dead yet, which is a good start. It's currently stuffed onto the microwave in the kitchen right now, lol.

LOL! I SO read that wrong! Stuffed ONTO the microwave (not INTO)! My diversifolia seems to do fine in cooler temps (around 55F). I do keep it on the drier side in cool weather, though!

I keep all of them drier in Winter, sometimes too dry, lol.

Actually, there is room IN the microwave.... :D
