Giant litter tray

I'm looking for a super giant litter tray that will cover the whole width of an extra large dog crate (30in/76cm). 
Does anyone know where i can find one this big? I've had a quick scan of a few sights from google and cant find anything close to this size. 

Thanks!

We use dog beds from Home Bargains, although the large ones are just over 24" but they're only £3.99 

Or underbed storage trays from Poundstretcher, but again they are not quite that big.

I did think of dog beds but all the ones i've seen have little holes in the bottom! 
I will have a look though, thank you!

We use potting trays ( below) would they be any good

Potting trays don't look very deep from the pictures on google, how are they for keeping litter and hay in? 

Those bunnies make them look very comfy though!

We like them as they are great for old and disabled bunnies and there is plenty of room for two buns to snuggle up together comfortably. There is hay that falls out when the bunnies
are jumping in and out or if you have one like Barry who buries himself under the hay and then walks off with most of it trailing behind him

They are shallow .

The Home Bargains ones don't have holes, if you have a store near you
