I have a real problem to keep my bathroom always clean , especially after moving to new flat without a place to flush all the water from the ground so how you keep it clean and dry.

Boxes or stones on the ground. I cleanup all products daily so when I want to scrub it, I can. I keep wipes on hand, which are quicker. A microfiber towel on the handles after makes them shine. Use the same cloth on the toilet. Spray shower with cleaner. Let it sit. Rinse.
