Expert Reply:

Replacement toilet floor flanges are universal so it will work, but you can determine the correct one based on the threading of your current flange. They will work with 3" pipes which you need to have as well.

- Male Thread: Replacement RV Toilet Floor Flange - 3" MPT # T05-0782

- Female Thread: Replacement RV Toilet Floor Flange - 3" FPT # T05-0784

These will also require the Valterra RV Toilet Floor Gasket with Hold Down Bolts # Q23653VP.

This will allow you to install a toilet like the Dometic Part-Timer RV Toilet # DOM57FR or Dometic Weekender RV Toilet # DOM24FR.
