What Is Over The Toilet Storage?

I was asked what is over the toilet storage by a lady at work. I thought “what world are you living in lady?” It turns out that after I explained it to her, she knew what it was but by a different name. In fact, she said she had a storage cabinet over the toilet in each of her bathrooms. I was impressed, as I still hadn’t got mine put up. I asked her did she installed hers herself and she said yes for two of them. The other two were in the bathrooms already when she purchased her home. Lucky her.
