I have a pertaining question to any sort of Ghusl that we do (wajib). What is the ruling on if your body parts such as hands legs or fingers touches the side areas such as walls or glass door during ghusl? Is ghusl still valid or we need to purify those walls with water too? As those places are already wet because of water reaching there prior we started our ghusl.

The reason for the question is because we are living in west and also I dont believe we have to purify the inner area in the washroom but your assistance or clarification can help me.
