Large Sand Baths

[Black_Inky_Eyes]

So one aspect I want to include in my hamster's natural cage is a larger sand bath because my current Syrian has currently taken a huge liking to them, unlike all my past Syrians. He uses the corner as a litter tray and the other one as bathing, digging and cleaning area. His corner tray is fine but his other bath is just a small tray and just put it in there not expecting much but surprised from his liking to them.

I want to dedicate a large area of the cage to sand bathing area but can't find a large enough bath. Does anyone know of anything? I want a bath/tray and not just section the sand off but bendy bridges because I find the sand gets everywhere. I've seen people use acrylic trays but those are way too expensive for me. Does anyone know any?

Also as a side note this has nothing to do with the topic but does anyone know good brands of Aspen, I've been looking at a 14.5kg bale called Aspen Bed 1?
