Chosen because it’s was a best seller

buy any kind that has a handheld sprayer. You'll be able to use it on your new toilets as well and you can use it to clean your bathroom, spray soiled clothing off over the toilet (great if you have kids or pets: you can spray down clothes with vomit/feces/food before putting in washer). Beware that the most common complaint is that they leak if you pull the sprayer too much so read reviews carefully.

Anything like this one should do

Get you one of these bad boys
