Piece of plastic tongue and groove (GU52)

Could anyone make use of this? The size is 240 x 26 x 1 cm. The Colour "shades of grey" as in close-up photo. It is very strong material. We used it to make a replacement side of a bath. I think it can be used to make a splashback for a shower etc. It just fitted in our medium size hatchback car.
