Will Dometic 311 and 310 Replace a Dometic 210 RV Toilet
Updated 11/17/2025 | Published 12/13/2024
Question:
Are both the Dometic 310 and 311 toilets a direct perfect fit in replacing a Dometic 210? I know the rough in 10” is the same. Is the flange the same? Do they come with the floor gasket, etc? Thanks

Hey Jeff, yes the Dometic 311 part # DOM67FR and the 310 part # DOM57FR will install in place of a 210 without any modification since like you said they both have the same rough in dimension. These come with new gaskets as well and everything needed to install.

Hey Jeff, how did the swap from your Dometic 210 to the 310 or 311 toilet go? Did the new gasket and hardware make the fit as smooth as expected? Your update could make it easier for the next person doing the same replacement.
