The sink area is the most visible part of the bathroom, so decorating it well makes the whole restroom look better. A clean sink setup starts with matching items because matching items look planned and expensive. Use one soap dispenser and one toothbrush holder in the same style, then add a small tray under them so the counter looks organized instead of scattered. Keep only the daily items on the counter and hide the rest. Add one small touch like a tiny plant, a small vase, or a simple candle, but do not add too much because bathrooms become messy fast. The key is leaving some empty counter space so it feels tidy and hygienic. When the sink area looks clean, the whole bathroom looks cleaner even before you do extra decor.
Simple example: Put a soap dispenser and a small hand lotion on a tray, then keep your toothbrush in a holder, and your sink area will look neat instantly.
