La sala de escape tiene una ambientación temática y utilería.

In Spanish, the pattern noun + de + noun often names a type or purpose, and the second noun is usually kept in the singular.

So:

• sala de escape = escape room
• salas de escape = escape rooms

Even when there are many rooms, the word after de usually stays singular because it describes the category, not the number.

Yes. In this context, escape is a borrowed word from English that many Spanish speakers understand, especially in the phrase sala de escape.

Depending on the country or speaker, you may also hear:

• escape room
• cuarto de escape
• juego de escape

So escape here is functioning like a noun in Spanish, even though it comes from English.

Because the sentence is saying what the escape room has, not simply that something exists.

• Tiene = it has
• Hay = there is / there are

So:

• La sala de escape tiene una ambientación temática y utilería.
  = The escape room has themed atmosphere/decor and props.

If you used hay, the structure would be different, such as:

• En la sala de escape hay utilería.
  = There are props in the escape room.

They are related, but not exactly the same.

• decoración usually focuses more on decoration itself
• ambientación suggests the overall atmosphere, setting, mood, or immersive feel

For an escape room, ambientación is a very natural choice because it implies more than just objects on the walls. It suggests the whole themed environment.

So ambientación temática sounds a bit more immersive than just decoración temática.

Here, temática is an adjective modifying ambientación.

• ambientación = feminine singular
• temática = feminine singular adjective agreeing with it

So ambientación temática means something like themed atmosphere / thematic setting.

Be careful: temática can also be a noun in other contexts, where it means theme or subject matter. But in this sentence, it is an adjective.

Utilería refers to props, especially the objects used as part of a setting, performance, or scene.

It is very common in areas like:

• theater
• film
• TV
• themed experiences such as escape rooms

So in this sentence, utilería means the physical props or set pieces used to support the theme.

In Spain, you may also hear atrezzo for this idea. In Latin America, utilería is very common.

Because utilería often works like a collective or mass noun.

It is similar to how English sometimes uses words like equipment or furniture:

• one piece of furniture, two pieces of furniture
• not usually furnitures

Likewise, utilería can refer to the whole set of props as one category, even if there are many individual items.

Because one article can introduce a coordinated phrase.

Here, una naturally covers the first noun phrase, and the second noun is added with y:

• una ambientación temática y utilería

This is fairly natural, especially because utilería behaves like a mass/collective noun.

You could repeat the article in some contexts, but it is usually unnecessary:

• una ambientación temática y una utilería sounds less natural here

So the original version is the more natural phrasing.

Yes, in many places you can. Because this is a modern entertainment concept, English is often used directly.

Depending on the region, you may hear:

• sala de escape
• escape room
• cuarto de escape

If your goal is more Spanish-heavy wording, sala de escape is a good choice. If you are speaking with people who work in the industry, escape room may also be very common.

Because y only changes to e before a word that begins with an i sound.

Examples:

• padre e hijo
• España e Italia

But utilería begins with a u sound, not an i sound, so it stays:

• ambientación temática y utilería

So y utilería is correct.

It is pronounced with the stress on rí because of the accent mark:

• u-ti-le-RÍ-a

A rough English-friendly guide would be:

• oo-tee-leh-REE-ah

That written accent is important because without it, the stress would fall somewhere else.
