In an ideal world, no one would be left in a wet bed ever. However, we dont live in an ideal world. Once the wet bed is discovered, staff should change it as soon as they can- That will depend on the PWD and their needs and the availibilty of staff to actually do it.
Its not great but, a person that needs hoisting and can be aggressive, needing two or maore carers is likely to be left longer than someone who will quietly sit in a chair whilst the bed is changed by one carer.
Running water in the room isn't a'' must have''. However, the person should be washed regularly and should have a reasonable level of hygiene. Surely there are ''on the corridor'' showers that she could be showered in?
If wetting is a regular occurrance, does she wear a pad?
