yahari mainiti tukau basyo dakara, yokusitu ga kirei ka douka mo daizi desu.

やはり means something like as expected, after all, or just as you’d think.

In this sentence, it gives the feeling of:

• when you think about it
• after all
• it makes sense that

So it adds a natural, slightly reflective tone:

• やはり毎日使う場所だから… = After all, since it’s a place you use every day…

You will also often see やっぱり, which is a more casual version of やはり.

毎日使う場所 literally means a place that (you) use every day.

This is a very common Japanese pattern:

• a plain-form verb comes before a noun
• the verb phrase modifies the noun directly

So:

• 使う場所 = a place [that someone] uses
• 毎日使う場所 = a place [that someone] uses every day

In English, we often need that, which, or where, but Japanese does not.

So:

• 毎日使う場所だから = because it is a place you use every day

When a verb modifies a noun, Japanese normally uses the plain form, not the polite -ます form.

So:

• 使う場所 = correct
• 使います場所 = not natural / incorrect in standard grammar

This is true even in polite sentences. The sentence can end politely with です, but the modifier before the noun still stays plain:

• 毎日使う場所だから、…大事です。

That mixture is completely normal:

• plain form inside the sentence
• polite form at the end

毎日 often works as a time expression without a particle.

So:

• 毎日使う = use every day

This is very common with words like:

• 今日 = today
• 明日 = tomorrow
• 毎日 = every day
• 去年 = last year

You usually do not need に with 毎日.

So:

• 毎日に使う is not correct here
• 毎日使う is the natural form

だから means so, therefore, or because that is the case.

In this sentence, it connects the reason to what follows:

• 毎日使う場所だから、… = because it’s a place you use every day, …

It is based on だ + から.

A few similar patterns:

• 静かだから = because it’s quiet
• 便利だから = because it’s convenient
• 毎日使う場所だから = because it’s a place you use every day

So here, だから introduces the reason why the next point matters.

X かどうか means whether X is the case or not.

So:

• 浴室がきれい = the bathroom is clean
• 浴室がきれいかどうか = whether the bathroom is clean or not

This whole part becomes a noun-like clause, so it can act as the subject or topic of the next statement.

You can think of it as:

• [whether the bathroom is clean or not] is also important

This pattern is extremely useful:

• 行くかどうか = whether someone will go or not
• 好きかどうか = whether someone likes it or not
• 便利かどうか = whether it is convenient or not

This is a very common learner question.

きれい is a na-adjective, and before かどうか, you normally do not use だ.

So the natural form is:

• きれいかどうか

not:

• きれいだかどうか

The same thing happens with nouns in many cases:

• 学生かどうか = whether someone is a student
• 静かかどうか = whether it is quiet
• きれいかどうか = whether it is clean

So although きれいだ can be the plain predicate at the end of a statement, before かどうか the だ is usually dropped.

In 浴室がきれいかどうか, the part 浴室がきれい is a mini-sentence:

• 浴室 = bathroom
• が = marks the thing being described
• きれい = clean

So:

• 浴室がきれい = the bathroom is clean

Then that whole statement is turned into whether the bathroom is clean or not by adding かどうか.

The が belongs inside that embedded clause. It is not the main subject of the entire sentence in the usual sense; it is the subject of the smaller statement 浴室がきれい.

も means also or too.

So:

• 浴室がきれいかどうかも大事です = whether the bathroom is clean or not is also important

The speaker is implying that this is one important point among others.

Without も, the sentence would simply say it is important. With も, it suggests:

• this is not the only important thing
• this is another important factor

大事です means is important.

Here, the thing being called important is the whole clause before it:

• 浴室がきれいかどうかも = whether the bathroom is clean or not also
• 大事です = is important

So the structure is:

• [whether the bathroom is clean or not] is also important

This is a very common Japanese pattern where a long clause comes before 大事です, 必要です, 問題です, and so on.

Examples:

• 毎日続けることが大事です。 = Continuing every day is important.
• 安全かどうかが問題です。 = Whether it is safe is the issue.

Not exactly.

浴室 is a more specific and somewhat formal word meaning bathroom / bath area / shower room.

お風呂 can mean:

• the bath
• the bathwater
• the bathtub
• sometimes the bathroom/bathing area, depending on context

So in a sentence about cleanliness in housing or facilities, 浴室 sounds precise and natural because it refers to the bathroom area itself.

The subject is not stated explicitly, which is very normal in Japanese.

From context, it usually means:

• you use every day
• people use every day
• one uses every day

Japanese often leaves out subjects when they are obvious from the situation.

So:

• 毎日使う場所 does not literally say I use, you use, or we use
• the listener understands it from context

In English, we usually have to choose a subject, but Japanese often does not.

It helps to break it into two big parts:

1. やはり毎日使う場所だから、

   • after all, because it is a place used every day

2. 浴室がきれいかどうかも大事です。

   • whether the bathroom is clean or not is also important

So the full logic is:

• Since it’s a place you use every day, whether the bathroom is clean or not is also important.

This kind of structure is very common in Japanese:

• reason first
• main point after

The comma shows that the first part sets up the reason for the second part.
