Using your own name for your .PLUMBING domain name can work sometimes
If you are creating a personal website, a blog, a podcast, or any other website like this, registering your own name as a .PLUMBING domain name may make sense.
Considering your brand identity is rooted in your personal identity, it can work as long as you are comfortable having your name listed online.
