Lucky bamboo isn't technically bamboo, but it makes a great houseplant nonetheless! They'll do well in a bathroom that has indirect light, and shouldn't be exposed to direct sunlight. The best part about growing lucky bamboo is that you don't even need to grow them in soil, making them an even more beautiful decorative addition to your bathroom. Keep lucky bamboo in a container with pebbles with the water level above the roots and you'll be good to go.
