How to display drupal user page tabs on 3 different page
One quick solution to hide the tabs is to change the menu type form tabs to callback:

/**
 * Implements hook_menu_alter().
 */
function yourmodule_menu_alter(&amp;$items) {
  $items['user/login']['type']    = MENU_CALLBACK;
  $items['user/register']['type'] = MENU_CALLBACK;
  $items['user/password']['type'] = MENU_CALLBACK;
}


You could render the user register form whatever you want with this:

$elements = drupal_get_form("user_register_form"); 
$form = drupal_render($elements);
echo $form;
