We are replacing our old sky blue toilet, and I am planning to plant some flowers in it. I put it outside and cleaned it up, but the water (halfway up the bowl) will not drain out. I found one person with the same problem on the internet, and people suggested that she drill a hole with a ceramic drill bit (sounds expensive, and I am worried we would break the toilet). Would getting the water out, filling the bowl to the waterline with gravel, and then adding the potting soil and plants solve my water problem? I am hoping the plants would suck up any water that stuck around... any ideas?
