That would depend on what habits your family practices in the bathroom. Every time the toilet is flushed, microscopic bits of fecal matter (fecal flora) are aerosolized and travel fifteen or so feet through the air. In most bathrooms, this is plenty of room for the fecal flora to settle on toothbrushes, drinking glasses, towels and everything else. The only way to minimize this is to put down the lid over the toilet seat before you flush.
There is more bacteria in the bathroom than in the kitchen, especially in this day of anti-bacterial cleaners and hot dishwashers. I think that most people know about the gross kitchen sponge thing. I haven't used a sponge in my kitchen for a couple of decades.
Actually, tests have shown that the average kitchen sink is dirtier than an average toilet--this is because you're constantly running rich sources of nourishment for bacteria through them, that is, food waste. Toilets, on the other hand, constantly flush the waste through very efficiently. However, if you're diligent about cleaning your sink after every meal--ordinary cleanser, like Comet or Ajax, will do the job admirably--you won't have that situation.
