The general rule for hotel etiquette is that if an item is intended for single-use or is "consumable," you are welcome to take it; if it is part of the room's permanent furnishings, it must stay. In 2026, it is perfectly acceptable to take toiletries (shampoo, soap, lotion), disposable slippers, the complimentary stationery, and coffee/tea pods. However, taking towels, bathrobes, bed linens, coat hangers, or hair dryers is considered theft and will likely result in a charge to your credit card after checkout. Many modern hotels are switching to bulk wall-mounted dispensers for soap and shampoo to reduce plastic waste; in these cases, taking the product is impossible, and attempting to remove the bottle is definitely a "don't." If you truly love a specific hotel's branded robe or pillows, most high-end properties now offer a "boutique" or online shop where you can purchase brand-new versions of these items legally and with a clear conscience.
