My basement bathroom has drop ceiling currently and it's rather a large area with all plumbing there (from top 2 bathroom):
It is almost 3x5 feet area.
If I cover most with drywall and have access panel, how large of an access panel is needed?
OR should I have multiple access panel? What is the right way to do this to hide the obvious access panel to make it somehow "flushed" to the ceiling?
I rather NOT put the drop ceiling there again.
