When you say 'practically new' how long are ypu actually talking? Tiles tend to have a shelf life with suppliers of 3 years or so. So you may struggle to get them again. However, you would need to start with the usual suspects such as Topps Tiles, B & Q, Wickes etc before moving onto specialist suppliers. Good luck!

Hi Sunny, I'm guessing the layout is like this then? Which is why you wanted a 900mm wide shower. I'd actually go with the 900 x 1200 as it's longer and will suit the room better, plus, if the layout is like this, then you have the room for it. Here's a link to all those in that size from Victorian Plumbing, so depends what your style is. Victorian Plumbing. They sell loads, so i'm sure you'll be able to find one that will suit. One thing to watch out for is the size of the basin and toilet. You will be better off with a short projection toilet and don't come out too far with the basin either as the space to exit out of the bath will be lessened. Regards to flooring, tiles etc, that's personal choice. What style do you like, what colours do you like, and most importantly what is your budget for the project?

I found this link. I don't think it's the exact one but similar. Are they terracotta? https://norfolkreclamation.co.uk/all-stock/roofing/all-other-roofing/batch-of-1440-red-clay-fish-scale-tiles-by-wade-cherry-hornsea/ Worth a call to them anyway.
