Welcome to the Bunnings Workshop community @Luvliestaz1. We trust that you'll get loads of helpful information, advice and inspiration for all your projects around the house and garden from our amazing members. We're pleased to have you join in the discussion.
Let me tag a few helpful members in @Former Workshop member, @JDE and @redracer01 but I imagine their advice will be fairly straightforward - engage the services of a qualified and reputable plumber.
Looking forward to seeing how you can improve your bathroom (with a little help from a qualified tradesperson).
