TV series that seen in the bathroom (4)
I believe the answer is:
soap
'tv series' is the definition.
(soap opera is a type of TV series)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for soap that I've seen before include "TV programme; cleanser" , "Cleaning substance - melodramatic TV or radio series" , "cake?" , "Serialised drama" , "Bathroom item" .)
