Im afraid i have to hold my hand up and admit i have made a mistake, i have striped the tiles of the wood and i have noticed that the wood is not level with the bath it is aprox 4mm below the level , i thought by adding the tiles it would bring them level and not cause a problem. I am thinking now of not putting the tiles back on and using something to that will completely seal it. Would i be better adding something that as a lip that will go over the edge of the bath . Any help would be apreciated . Thanks
