I can't believe that no one has mentioned the famous shower orange yet. On Reddit there is a whole subreddit dedicated to it.

A cold orange in the shower is perfect – it's refreshing, it smells great and you don't have to deal with the usual mess of eating an orange.

Something hot in an open bowl sounds like the worst food to eat in a shower TBH.

I'd go with something cold in a tube, like an ice pop. Or maybe a beer in one of those fancy insulated tumblers with a closeable lid.

For fast eating challenge try cotton candy

Cured sausage. It doesn't dissolve or absorb water.

What the hell is wrong with people...

Beer.

I enjoy eating peaches in the shower Any messy fruit, really, but stone fruits in general.

You can just shamelessly get in there, get that nectar all over your face, and enjoy it. Probably more enjoyable if you have a beard and need to eat carefully.

I no longer drink, so this is like my shower beer now.

I prefer to run a hot bath with a bunch of bouillon cubes. I bring salad and breadsticks in with me for the unlimited experience Olive Garden promises, but refuses to actually provide paying customers.

Mangoes because you can go primal without a care

My next door neighbor makes meals in his shower after getting a garbage disposal installed.

Mango. Otherwise you just end up with a mess

Crunchwrap supreme. Next question.

Grapes.

Does beer qualify as a food?

A peach. I prefer to eat my oranges segment by segment, so I don’t really find them messy, but a good, ripe peach should be messy as hell.

Most fruit seems to be a good choice IMO. Even veggies may be a decent option. Grapes maybe?

Fruit is generally waterproof, so it's not like it will taste different in the shower.

I think anything with flour is probably a bad choice. Nobody likes soggy bread/cake/whatever.

I'd also consider any kind of cheeses or cured meat. Maybe a nice meat/cheese/fruit assortment?

Can it be a bath instead of a shower?

None.

Tropical fruit, so I can relive my trip to Thailand

There's the classic shower beer, and that's actually really fun. Like others said, be careful & if you want to be extra cautious, aluminum cans only or poured into a stainless steel vessel.

When I was a fat little teen, I somehow heard the idea of eating potato chips in the shower. I tried it & it was oddly satisfying. They were Ruffles. I only did it once or twice total, it would be kind of weird to do all the time.

Shower beers, however....always a good idea.

Everyone saying mango because of that meme but the answer is obviously WATERMELON. It's got water right in the name and is just as messy as mangoes!

Vegetables and fruits. You'd wash them first anyway.

BBQ on the bone - I haaate messy meals, so let's set up a table with slaw, taters and a nice rack slathered in sauce, get naked, and turn on the water.

None

An orange. Apparently it is a life changing experience according to a group on that other site.

Beer.

1. Liquid

2. Calories

3. Uh...

Smoothies from a closed-lit container and a straw.
