Can I convert my bathroom into a green house?

Ok, I am going away on vacation at the end of May and I can’t find anyone who will be around to babysit my plants. I will be gone for 10 days and my plants won’t be watered for 8 to 9 days.

I have a skylight in my guest bathroom and was wondering if I fill the tub with water and close the door if all my plants will do well there. I have one plant in there now that goes a long time between waterings but it is a smaller plant.

I have some larger plants that I worry may suffer from not getting watered. I have stretched its water time to 5 days but I don’t know if they can dry out that long. The room does get humid if the sun is strong and I close the vent and people are using the bathroom.
The sun shines in the tub, so I figured if I leave some water there that it may make the room humid enough for the plants to get moisture. Will this work?
