Woocommerce 2.1.6 shop page

I’m trying to remove the white space on the right of my Woocommerce shop page so that the page is full width. I know this has been covered before in these forums but not it seems for the latest version 2.1.6 which is much changed. There is no PHP or template for the shop page and I just have no clue where to make the change.
I have a twenty eleven child theme in which I have changed page widths but Woocommerce ignores it.
Driving me mad, please help.
