Get product custom attributes to display them in WooCommerce product loop

I'm working in a woocommerce site (Real Estate) and I don't get to show product custom attributes on my front shop page (Eg. Square meters, Rooms, Toilets, etc). I'm trying to use the code below but I can make it work. With the code I have I'm just able to show product ID but when it comes to attributes it only shows the word "Array" or just "Nothing" when I put the attributes IDs in the code.

The is the code I have:

add_action('woocommerce_after_shop_loop_item_title', 'cstm_display_product_category', 5);

function cstm_display_product_category()
{
    global $product;

    $productAttribute = $product->get_id();

   //if(isset($productAttribute)){
       echo '<div class="items" style="color: #fff;"><p>Output: ' . $productAttribute . '</p></div>';
   //}
}

You can see the output live here

Whatever help or guide you can give me to be able to achieve this, will be so much appreciated. I'm a noob in this matters.

P.D. I'm inserting this code in my functions.php file.

Wordpress is up to date. Woocommerce is up to date.

With product attributes (custom or not), you can use the WC_Product method get_attribute() where you can input an attribute name, slug or taxonomy. So in your code:

add_action('woocommerce_after_shop_loop_item_title', 'display_custom_product_attributes_on_loop', 5 );
function display_custom_product_attributes_on_loop() {
    global $product;

    $value1 = $product->get_attribute('Square meters');
    $value2 = $product->get_attribute('Rooms');
    $value3 = $product->get_attribute('Toilets');

    if ( ! empty($value1) || ! empty($value2) || ! empty($value3) ) {

        echo '<div class="items" style="color: red;"><p>';

        $attributes = array(); // Initializing

        if ( ! empty($value1) ) {
            $attributes[] = __("Square meters:") . ' ' . $value1;
        }

        if ( ! empty($value2) ) {
            $attributes[] = __("Rooms:") . ' ' . $value2;
        }

        if ( ! empty($value3) ) {
            $attributes[] = __("Toilets:") . ' ' . $value3;
        }

        echo implode( '<br>', $attributes ) . '</p></div>';
    }
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.

Automate the code from a simple array of product attribute names:

The code below will gives the same output, but it's compacted, optimized and requires just an array of your desired product attributes:

add_action('woocommerce_after_shop_loop_item_title', 'display_custom_product_attributes_on_loop', 5 );
function display_custom_product_attributes_on_loop() {
    global $product;

    // Settings: Here below set your product attribute label names
    $attributes_names = array('Square meters', 'Rooms', 'Toilets');

    $attributes_data  = array(); // Initializing

    // Loop through product attribute settings array
    foreach ( $attributes_names as $attribute_name ) {
        if ( $value = $product->get_attribute($attribute_name) ) {
            $attributes_data[] = $attribute_name . ': ' . $value;
        }
    }

    if ( ! empty($attributes_data) ) {
        echo '<div class="items" style="color: red;"><p>' . implode( '<br>', $attributes_data ) . '</p></div>';
    }
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.
