Litter box disguised as a potted plant - does anyone have one of these?

I'm considering getting this litter box disguised as a plant pot : http://www.goodpetstuff.com/Images/hiddenlitterpic.jpg

Does anyone here have one of these? If so, can you give me the dimensions of the interior of the litterbox portion, or can you tell if perhaps it's big enough to fit a Booda Dome litterbox inside?

I'd like to get one to hide a litterbox in, but since it's rather expensive I wonder if I could fit a smaller, more easily replaceable litter box inside it. Since plastics absorb odors over time, it would be cheaper to replace a 'liner' box than the plant box.

Any feedback on these is appreciated!

You mean just the bottom part of a Booda Dome right?

Ideally, the whole dome (for the occasional spray). The bottom part would help, though, if the whole thing wouldn't fit.

I have one cabinet for a litter box as well as a dome. Basically I would recommend just dealing with the booda dome because that would be a royal pain to get to the box with the lid on.

I sprayed the interior or my wooded box with water proofing sealer.
