What is the process for figuring out what water features and elements should be included in our pool?

Many features are purely aesthetic but there are times where even the acoustics come into play (blocking out street noise, etc.). And prices vary significantly so start with cost estimates and then prioritize what is most important for you. Some water features can be added after construction. Many cannot. If the pool design includes a raised wall and/or raised spa, features built into that raised area are often incorporated into the pool in those areas.
