Hi, I can no longer share a bathroom with my kids, its impossible. I have a big jetted tub downstairs, the faucet is on the side of the tub facing out, and tile is around the tub, all of it was poorly installed, the plumbing and everything works good, but they did a bad tile job. I want to add a shower to it, is this possible with not a lot of expense. Thank you, Jodie
