Removing columns in WooCommerce

I’m hoping there is someone out there who can help me? Been bashing my head against WooCommerce for half a day now!

I am using my own custom 960 24col grid that I want WooCommerce to conform to. Unfortunately I can’t seem to turn off the default columns built into WooCommerce – is there a simple way to do it? I’ve tried editing the functions.php file in my template with this:

// Change number or products per row to 1
add_filter('loop_shop_columns', 'loop_columns');
if (!function_exists('loop_columns')) {
function loop_columns() {
return 1; // 1 product per row
}
}

but it isn’t working for me.

Ideally I’d just like to have 1 column so I can resize dynamically – but this is proving difficult impossible currently!

Many thanks!
