This may seem strange but bear with me…
I have an antique claw-foot bathtub with turn-of-the-century pipe fittings, faucet, etc…
I find that a full, wrap-around shower curtain to be slightly claustrophobic.
Is it possible to build a custom planter box that wraps around the back 3/4 of my tub (against the wall which contains a window), fill it with low to mid-light plants that love high humidity and just have a curtain on the non-plant-wall side of the tub?
What are the green-thumb’s thoughts on this?
I would put the planter on legs so as not to trap unwanted moisture.
Thanks Tyler! Great answer!
