I have a corner 10 " rough-in toilet in my apartmant that I have to replace, but I can not find this type of toilet anymore on the market. Does someone still make corner 10 " rough-in toilets? If not, what are the options? Thanks.
Eljer makes a corner toilet. Check their website to see what the rough is. You need to look closely at the spec sheet to be sure you are measuring the rough on this corner toilet the same way they call it out.
I don't know anyone who ever made a 10" rough corner toilet. The Eljer Triangle is the only one I am aware of from a known manufacturer and that measures 12" from both walls.
