-고 나서 means after doing X, then... It shows that one action is completed before the next action happens.

So in 샤워하고 나서, the order is:

• 샤워하고 나서 = after showering
• 수건을 욕실에서 말려요 = dry the towel in the bathroom

Compared with just -고, -고 나서 makes the sequence a little clearer and stronger.

Both are possible, but 샤워하고 is very common and natural in everyday Korean.

샤워하다 is a noun + 하다 verb:

• 샤워 = shower
• 하다 = do

So these are related forms:

• 샤워하다 = to shower
• 샤워를 하다 = to do a shower / to take a shower
• 샤워하고 = shower + and/after

In casual everyday speech, Korean often drops the 를 in these noun + 하다 expressions, so 샤워하고 sounds smooth and natural.

Korean often leaves out the subject when it is clear from context.

So even though English usually wants I in a sentence like After showering, I dry the towel in the bathroom, Korean can simply say:

• 샤워하고 나서 수건을 욕실에서 말려요.

The listener usually understands the subject from the situation. This is very normal in Korean.

을/를 marks the direct object of the verb.

Here, 수건을 means the towel is the thing being dried:

• 수건을 말려요 = dry the towel

That tells you 말리다 here is being used as a transitive verb, with an object.

If you used 수건이, it would change the structure and meaning.

No. 수건을 말려요 means I dry the towel.

That is important, because English dry with a towel can mean dry your body using a towel, but Korean does not express that with 수건을 말리다.

If you want to say I dry myself with a towel, you would say something more like:

• 수건으로 몸을 닦아요 = I wipe/dry my body with a towel
• 수건으로 몸을 말려요 can sometimes be understood, but 닦아요 is more common and natural for drying your body after a shower

So in your sentence, the towel itself is what gets dried.

에서 marks the place where an action happens.

Since 말려요 is an action, 욕실에서 means:

• in the bathroom
• at the bathroom location where the drying happens

So:

• 욕실에서 말려요 = dry it in the bathroom

By contrast, 에 often marks:

• destination
• existence/location
• time
• sometimes a target surface or condition

For a simple location of an action, 에서 is the normal choice.

This is a very common question.

• 말리다 = to dry something, to make something dry
  
  • transitive
  • takes an object
• 마르다 = to become dry, to dry on its own
  
  • intransitive
  • no direct object

Examples:

• 수건을 말려요. = I dry the towel.
• 수건이 말라요. = The towel dries / becomes dry.

So in your sentence, 말려요 is correct because a person is doing the action to the towel.

This is just the regular polite present-style conjugation.

말리다 ends in -리다, and when it conjugates with -어요, it becomes:

• 말리어요 → 말려요

This kind of contraction is normal in Korean.

So:

• dictionary form: 말리다
• polite form: 말려요

Yes. 말려요 is in the polite present style, but Korean present tense often covers several ideas that English splits up.

Depending on context, it can mean:

• I dry the towel
• I’m drying the towel
• I usually dry the towel
• I dry the towel after showering

In a sentence like this, it often sounds like a habitual action: something the speaker normally does after showering.

Yes. Some common alternatives are:

• 샤워한 후에 = after showering
• 샤워한 다음에 = after showering
• 샤워 후에 = after the shower

These are all possible. The differences are mostly about style and nuance:

• -고 나서 feels very common and conversational
• 후에 can sound a little more formal or written
• 다음에 is also very common and natural

So 샤워하고 나서 is a very everyday spoken choice.

The sentence is understandable and basically natural, but in real life a Korean speaker might sometimes use a more specific verb depending on what exactly they do with the towel.

For example:

• 수건을 걸어 둬요 = I hang the towel up
• 수건을 널어요 = I hang the towel out to dry
• 수건을 욕실에 걸어 말려요 = I hang the towel in the bathroom to dry

Why? Because 말리다 focuses on drying, while 걸다 or 널다 focuses on the physical action of hanging it.

So your sentence is fine, but if you want to sound more specific and natural in a daily-life context, 걸어 두다 or 널다 may be useful.

Yes. Korean word order is flexible as long as the particles stay correct.

For example, these are all possible:

• 샤워하고 나서 수건을 욕실에서 말려요.
• 샤워하고 나서 욕실에서 수건을 말려요.

Both are natural. The difference is mainly about what the speaker wants to emphasize a little more.

In Korean, particles like 을 and 에서 are what make the roles clear, so the sentence can move around more easily than in English.
