Where to put a drink on a makeup vanity
Give your drink a dedicated, fully supported spot outside the path of your hands, cords and hot tools. If you cannot make that space, use another stable surface.

Start with the routine, not the accessory
Sit where you normally get ready. Notice where your hands reach for brushes and where cords travel. A drink belongs outside those paths, with room to pick it up without reaching over tools or open palettes.
Make a supported space
Steadi needs 5.2 inches of tabletop for its whole footprint, plus clearance around it. It is not a shelf or a way to extend a table edge. Keep the tabletop and the holder dry and clean.
Separate drinks from powered tools
Do not treat a holder as protection for hair tools, lights, chargers or outlets. Keep the drink and its possible splash area separate. When a narrow vanity cannot offer that separation, use a nearby table or pause the drink until you finish.
Check before settling in
Fits drink container bases 2–3.15 inches across. Make sure handles clear the fins, the container is seated fully, and you can lift it comfortably. The holder helps resist tipping; it cannot prevent every spill.
