VEVOR Chafing Dish Buffet Set, 8 Qt 4 Pack, Stainless Chafer with 4 Full Size Pans, Rectangle Catering Warmer Server with Lid Water Pan Folding Stand Fuel Tray Holder Spoon Clip, at Least 8 People Eac

Yes, it is.

FOR Chafing Dish Buffet Set, Just buy solid wax.

I use any of the gels available. I use the starfrit gelled fondue gel, works great. Less chances for spillage as well. (CDN Tire)

The product comes with water tray and food tray.

You can use disposables and most other chaffing dishes

Another dish of the same size should be fine I use 2 half disposable chafing pans in them at times

You could try the same company .....but they generally come standard sized
