I am remodeling a master bath and I have removed a knee wall that contained an electrical outlet. I have rerouted the wiring up next to the drain stack. I would like to locate a junction box in the new drywall behind the new vanity. I will make it accessible inside the cabinet. I will route wiring up and over about 3 feet to put an additional outlet in the wall above and to the right of the vanity.My question is..Can I locate a junction box within a foot of the under sink plumbing.
It looks good and accessible. The NEC doesn't say it must be readily accessible only accessible, in case you need to inspect or maintain it. If you are feeling like you want to help another owner or an electrician later on down the road, you might even put a label on the panel saying there is an electrical junction box behind the panel. It could save some time in the future.
