Yes, it is generally recommended to close the door when showering. Closing the door serves several important purposes:
Privacy: Closing the door ensures that no one accidentally walks in while you're showering, giving you the privacy you need.
Safety: Closing the door can prevent slip and fall accidents, as water can make the floor slippery. Keeping the door closed can also help contain water within the shower area and prevent it from spilling onto the bathroom floor.
Temperature control: Closing the door helps maintain the warmth inside the shower area, creating a more comfortable and enjoyable showering experience.
Steam containment: When you close the door, the steam from the hot water is contained within the shower enclosure. This can help prevent excess humidity and moisture from spreading throughout the rest of the bathroom, which could lead to mold or mildew growth over time.
In some situations, such as in shared living spaces or when staying at a hotel, you might find bathrooms without a door or with only a partial door (e.g., a glass partition). In such cases, it's still essential to be mindful of privacy and safety by using any available signage or communicating with others in the household or hotel to ensure that you have privacy and won't be interrupted while showering.
