What is the purpose of the glass shower door bottom seal strip and how does it contribute to the functionality of a shower enclosure?

The purpose of the glass shower door bottom seal strip is to prevent water from leaking out of the shower enclosure onto the bathroom floor. It contributes to the functionality of the shower enclosure by creating a watertight seal at the bottom of the door, ensuring that water stays inside the shower area and does not cause damage or create a slipping hazard outside the enclosure.
