We recently bought 2 acres of land and want to add a pool. We have a lot of rock, so we think that the only economical choice will be an above ground. I am wanting the biggest I can get. Our yard is not level, so with the rock, I am thinking we will need to build up to make it level. I was looking at the pool factory and the prices are great, but my husband has concerns about installing it ourselves. Is it really best to buy the more expensive pool from someone local and have them installed? All the reviews I read talk about how easy it is to install.
