The basic difference between the two is that bacterias are prokaryotes while protists are eukaryotes, primitive eukaryotes specifically.
The two may not have a nuclear membrane but the genetic material present in them i.e. the DNA is of different types; the bacteria has circular DNA while the protist has any eukaryotic type of DNA. There are also differences in the type of ribosomes present, in the locomotory organelles present, for example, bacterias have flagella and protists like paramoecium have cilia present (some exceptions in protists have flagella too).
So, even if you do find them similar in appearance and structure there are a lot of major differences between them.
