    Question One toilet 12" Rough-in, other 2 are 13.5"

    I'm pretty sure I can replace one of our toilets in a straightforward manner because it has a twelve inch rough in. The other two, however, are a bit over 13". Would I be able to get away with installing a standard 12" toilet and have it just sit further out from the wall than the one it replaces, or should I use some type of flange modification to get it to fit? Or is there another alternative I'm looking at replacing the thirty-year-old A/S toilets with either:

    Toto Eco Drake

    Kohler Cimarron

    A/S Cadet 3

    All with round bowls.

    I agree with hj,
    I would never install a round bowl.

    Most of my sales are for the elongated.
    I found out years ago, that once someone had one elongated bowl, they would be coming back for more.

    Round bowls are a joke.

    If I thought I could get away with it, i would definitely rock the elongated bowl. But my parent's house has tiny bathrooms, and the toilets are right next to the doors. The current round bowls are even with the frame of the doors. I'm concerned that an elongated bowl would stick out too far and people would run into them when they walk in, or it might just flat-out look weird. Do they make compact elongated toilets that might fit in the space of a round bowl?

    But I could get a 12" rough-in toilet to mount well in all three bathrooms? Would I need a flange adapter of some sort to counter act the increased rough in

    Using a 12" toilet on the 13.x flanges will just have them sticking out further from the wall. Now, if your measurement is 13.25" or more, if you purchased the 14" one (they normally have 3/4" behind them), it would fit, just. What you may find out is an elongated toilet that ends up close to the wall is no longer than a standard 12" one sticking out those extra 2". I think all except for maybe one of the TOtos that use the unifit adapter are 1.6g toilets, though.

    Make sure you're measuring from the wall, not the baseboard.
