Remove product tabs

Paste the following code in your theme’s functions.php:

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

function woo_remove_product_tabs( $tabs ) {

    unset( $tabs['description'] );      	// Remove the description tab
    unset( $tabs['reviews'] ); 			// Remove the reviews tab
    unset( $tabs['additional_information'] );  	// Remove the additional information tab

    return $tabs;

}

Note: delete the lines of the tabs that are not meant to be removed.
