Hope it helps... It is best not to use a plywood for your backerboard... especially in wet areas... Pick up some densheild or hadri backer. If you have any questions let me know. One thing that is important is to ensure that you used a modified thinset and silicon all of the areas where tile meets glass or any other materials ie walls, do not grout these areas or the grout will crack. If you have to grout them to achieve a better look than use a clear silicon over the grout after it has dried. You can use a sanded or a non-sanded grout whatever you prefer for the look... I would seal all of the grout to avoid staining from the saltwater or beverage spills
