Идите наверх: туалет справа.

Идите is the imperative form used for:

• more than one person: Go
• one person politely: Go, in a respectful/formal way

Иди is singular and informal, used with one person you know well, a child, etc.

So Идите наверх can mean either:

• Go upstairs (to several people)
• Please go upstairs (to one person, politely)

Идите comes from идти, which means to go / to walk.

In directions, Russian often uses идти where English simply says go. So Идите наверх is a normal way to tell someone where to go.

A slightly more explicit alternative would be Поднимитесь наверх (Go up / Go upstairs), but Идите наверх is perfectly understandable and natural in many situations.

Наверх means upstairs, up, or to the upper floor / upper level.

It expresses direction, not location.

Compare:

• наверх = upstairs / upward (motion toward)
• наверху = upstairs / at the top (location)

So:

• Идите наверх = Go upstairs
• Туалет наверху = The toilet is upstairs

In this meaning, наверх is a fixed adverb, so it is written as one word.

Russian has many adverbs like this:

• наверх = upward / upstairs
• вниз = downward / downstairs
• вперёд = forward
• назад = back

A learner may want to split it into на верх, but in this sentence that would be wrong. The standard form here is наверх.

The colon introduces an explanation or clarification.

Here the structure is roughly:

• Go upstairs: the toilet is on the right.

The second part explains what the listener should know after going upstairs.

In English, you could also use a period or dash, but the colon works well in Russian for concise directions like this.

Russian normally omits the verb to be in the present tense.

So:

• туалет справа literally looks like toilet on-the-right
• natural English: the toilet is on the right

This is completely normal Russian.

If you want a fuller version, you could say:

• Туалет находится справа = The toilet is located on the right

But the shorter version is very common, especially in directions.

This is a very common learner question.

• справа = on the right → location
• направо = to the right → direction

In this sentence, the toilet is located on the right, so Russian uses справа.

Compare:

• Туалет справа. = The toilet is on the right.
• Поверните направо. = Turn right.

So the rule is basically:

• use справа / слева for where something is
• use направо / налево for where to move

Туалет is in the nominative singular.

That is because it is the subject of the sentence:

• Туалет справа = The toilet is on the right

Even though the verb is is omitted, туалет still functions as the subject, so nominative is used.

Also, туалет is a masculine noun.

In Russian, туалет is commonly used for a toilet / restroom / WC, especially in public places.

Depending on context, English might translate it as:

• toilet
• restroom
• bathroom

But in Russian, туалет usually focuses on the toilet/restroom space, not necessarily a room with a bath.

For a bathroom in a home, Russian often uses:

• ванная
• ванная комната

So in this sentence, туалет is the normal word for a public or building restroom.

Yes, Russian word order is fairly flexible, but this version is natural and clear for giving directions:

• Идите наверх: туалет справа.

Other versions are possible, for example:

• Идите наверх, туалет справа.
• Наверх идите: туалет справа.

But the original sounds straightforward and idiomatic.

In short:

• Идите наверх gives the instruction first
• туалет справа gives the key locating detail after that

The main stresses are:

• идИте
• навЕрх
• туалЕт
• спрАва

So roughly:

идИте навЕрх: туалЕт спрАва

A helpful note for English speakers:

• т is a clear t
• р in справа is rolled or tapped
• unstressed о in туалет is not pronounced like a strong English oh

You do not need a perfect accent to be understood, but getting the stress right helps a lot.
