Remove Product Reviews in WooCommerce

By default, the WooCommerce product page shows a “Reviews” tab that lets visitors leave reviews. If you want to remove the review system in WooCommerce on your WordPress site, add the following code to your functions.php file:

add_filter( 'woocommerce_product_tabs', 'sb_woo_remove_reviews_tab', 98);

function sb_woo_remove_reviews_tab($tabs) {
   unset($tabs['reviews']);
   return $tabs;
}
