Thank you for the link.
Have a look at https://www.wayfair.co.uk/diy-plumbing/sb0/shower-trays-panels-c1797310.html?curpage=1 Good selection and free delivery.
Can't post link as banned, but Plumbworld have vanity unit set well priced. Just don't pay attention to countdown offer as they are on offer regularly. Doesn't include basin tap/waste and toilet fixing/pipes.
Mira have the hole at the end.
Is the idea to hide the loo roll in one of the cupboards or drawers to keep toilet time interesting?
