I have a 2014 Oceanis 45 and we are having a persistent leak in the forward shower. The water gets between the aft wall and the removable panel and drains into the hull and then to the bilge. Unfortunately I'm afraid the standing water will grow stuff. The dealer has sealed it once with caulk but it still leaks. He is going to try again but I thought someone else may have dealt with this problem and have a goo suggestion.
