Hi I noticed today that my shower casing isn’t tightly secured to the rest of the unit There is a few mm gap down one of the sides Enough for some water to get in. ive tried to press it so it’s a tight fit but it won’t So I’ve used tape to squeeze that part down so it’s closed tightly ( I hope ) Is this dangerous ??? Should I get it looked at by a professional Also the unit itself is fixed against the wall but does wobble ever so slightly if pushed. is that dangerous ??
