I would never advise you to go against your tenant contract. That would be wrong and a trespass against your landlord. I would be willing to tell you that mine took about 20 minutes to install and uninstall, most of which was spent getting upset at myself for getting it wet while I still needed to screw some bits in.

But I’ve mostly seen people looking for the water wall because it seems “luxurious.” It’s immensely stupid, style over substance.
