The plastic trash can that is made today is perfect for bathroom with touchless faucets and automatic soap dispensers. This is the cheapest and easiest trash can to use for cleanliness. Plastic that is placed over stainless steel makes it even more robust while still being easy to clean.
The automatic model is sensor controlled and has a lid which quickly opens when the trash bag gets about 10 inches and 130 degree angles from the can's sensor. With normal usage, the power will last about 6 months with 4 D-size batteries. For those that do not require trash bags, the inner bucket can be easily removed and cleaned when the trash is removed and taken out.
