My 1920 English Tudor has wonderful toilets, great ceramic tiles and matching washstands, tubs and sinks. My Master bath toilet bowl has had a crack in it for many years but it has just begun to sweat, then leak. I have searched unsuccessfully for months for a matching beige toilet bowl. No luck. A pal suggests I not use the toilet for a few days, then use a heat gun to dry it completely and use epoxy on the crack. How do I epoxy the inside of the bowl? What do you all think of this solution? All advice greatly appreciated. Thanks?
