It really does not matter what the trend is when a person is standing in your bathroom. What are YOU doing? If you are adding two recessed med cabs to the wall above the vanity (for a two-sink or sink and vanity set-up) or at least one large recessed med cab above the vanity, then you can get rid of the existing one. But consider making that space a recessed shelf. It is handy!

I just remodeled and kept the medicine cabinet on the wall. My vanities were custom so the door of the medicine cabinet replicates the doors of my vanities in miniature.

I was toying with the idea of not having one at all but then decided more storage is better. I have wall to wall mirror treatment above the vanities.

I never considered getting the medicine cabinets above the vanities - I would find it inconvenient to reach over the counter AND above to get stuff.

Definitely keep your mirrored medicine cabinets. Mirrored medicine cabinets are a great storage option that does not necessarily look outdated if you find an adaptable design with functionality. And some have customization size options. For example, you can also get customized sizing where cabinets can be ganged together. For example, two 12 inch cabinets ganged together or two 15" ganged together would work where you can add lighting as an option and have interchangeable left or right open doors. It gives you alot of storage over your vanity.

They can be recces or surface mounted. And some of these mirrored medicine cabinets have integrated LED lighting, which can also offer a nightlight with dinner function. So, you will not only have lighting from your main bathroom, but an additional light source. I hope this helps.

Unless you have extra storage/enough storage to store everything currently in your medicine cabinets, it would be best to leave them in.
