An attached bathroom typically includes all the essentials, such as a shower or bathtub, a toilet, and a sink. Hotels often enhance these facilities with additional amenities like complimentary toiletries, plush towels, hairdryers, and even luxury features such as rain showers or heated floors in higher-end accommodations. This setup not only ensures hygiene but also saves time and effort, as guests can access the bathroom without leaving the privacy of their rooms.
