Waterproof box with a viewing window embedded in the bottom

Hello,

I am looking for a box/crate with a volume of approximately 100 liters. The box should be buried outside in the ground so that later, through a viewing window (approx. 30cm x 30cm), one can see inside. It should later be filled with bottles.

The box should have the following properties
-waterproof
-rot-proof
-The viewing window should, if possible, be walkable.

Has anyone ever seen or built something like this or how could this be best done?
So far, all considerations have failed.

Best regards, Dennis

Should this be decoration or do you want to access the bottles again?

If only decoration:

Sink the food barrel, fill it with bottles, and place/insert a plexiglass sheet.
Plexiglass of sufficient thickness is, however, not exactly cheap.

Otherwise, go to a glazier and have a suitable piece worked into a natural stone slab, which then also becomes heavy and not exactly cheap.
The slab must lie properly and there must be a support cut/sunken in the middle for the glass plate.

Best regards
Dirk Grafe

Alternatively, a correspondingly large aluminum box would also be an option. Here you could cut a viewing window into the lid and then attach a correspondingly sturdy glass plate on top and seal it with an external sealing compound. Regards, Dirk

Is this supposed to be decoration or do you want to get back to the bottles later?

I guess it's for keeping drinks cool in summer.

For the YouTube fetishists reading along, just search for "beer hideout" or "beer bunker."

Hi,

that's right, I could have expressed myself more clearly.
The bottles should no longer be accessible. It can be completely sealed.

100 liters is rather small, but if the area with the window is only 10 cm larger, that is already 64 liters with the same 40 cm height.
