I've read about cracked toilet bowls being a catasrophe waiting to happen and I can appreciate this, but I seek expert opinion based on my case. There is a crack across the top of the bowl that I have. It seems superficial but it goes from the inside, over the rim and down the outside so I am concerned over this. I can't find a toilet to match the color from the seventies (and don't want to do a 15,000 dollar redo)and I'm also not that happy with the new toilets as they don't seem to flush as well and make banging noises. My neighbor was renovating her bathroom and her toilet was in perfect shape, so her contractor took out her bowl and left it on my front porch. Cleaned it up and it sparkles like new.... Only problem is that when he was loosening the bolts it made a hairline crack on the base, near the bolts... My contractor said that that is acceptable because he puts a double seal and where the bolt is is just cosmetic.. that no water will come from the flush. He also says that is not a problem the same way the crack across the top of the bowl is. Can this be repaired or reinforced with an epoxy? And which do you think is better, the original with a crack across the rim or the one with the crack by the floor bolts? I doubt if he would put it in if it was totally wrong thing to do, but then I read things that contradict this... Can you support what we plan to do. I don't know what to think. Thanks.
