Mirror flush with the tiles?

...quite simply peanuts,

side pivot cabinet (visible in the picture) and/or WT under-counter tank. And just like that, the "box" is gone

Just a mirror

Tile-level with 6 ceiling spots + 2 lamps above the mirror

Tiles-like with 6 ceiling spots + 2 lamps above the mirror

...that's a good idea, the shower must be behind it, right?

On the left the shower, on the right the throne
But it's not really a new idea and you need the space for it, otherwise in my opinion it doesn't look good.

There are already bath towels, hand towels, and who knows what else... Well, one has more stuff, the other less, my wife also has over 200 nail polishes
