Blocking up the only window should not be taken lightly, but from the regulation point of view as long as ventilation is available such as a timer fan then it is permissible.
I see bathrooms without a window from time to time. Often they are in small houses or en-suites that have been added later. They are dark and usually have left over odours, but if there is no alternative.....
