Hi, Iam new here and am clueless about pools. I have a pool that is 16' x 34' w/ surface area of about 1300, about 30000 gallons roughly. It is a gunnite pool and our plaster is in really bad shape and needs resurfacing w/ waterline tile replacement. There is only one contractor in our area who resurfaces and he is asking $19,000 for the entire work or $14,000 for just resurfacing. This seems very overpriced, but I have no other choice where I live. I have seen pools that have the entire surface covered in Tiles. I know it could be expensive to do that. Can some one tell me what the advantages and downside to having all tile pool.
