If you went through each item on the above list, then you probably noticed that we did not put the string fixtures on it. While you may see people with string lights installed over their pool, it may not be wise to do so. Of course, if you do want to, then you should ensure that you have at least a 10-foot clearance above the water. This level is mandated.
The worry is if they fall in the water as some string lights will not be waterproof. With voltage running through them, this could end in lousy electrocution.
