Main Differences Between the Models
The models are very similar both in appearance and construction since the 320 series became an upgraded version of the 310 model. However, we noticed the following crucial differences:
- Dometic 310 has a round bowl, while the 320 series received an elongated and deeper bowl.
- Due to the rim in Dometic 320 toilet, users are safe from spills and frequent floor cleaning. Dometic 310 doesn’t offer a rim.
- The first model is equipped with a slow-close enameled wood seat. The second toilet features a full-size residential style wood seat.
- Dometic 320 is a bigger and heavier RV toilet.

Andy
Hi, thank you for the review. But I’m afraid foot pedal is not as long-lasting as conventional flushing. Am I wrong? Did anyone use such models?
Marcus Robertson
Hi, Andy! Thank you very much for your kind words and comment! Manufacturers claim pedal constructions stand as much flushing as conventional toilets. But they have an advantage of being more hygienic since you don’t have to touch it with hands.
Linus
Hello! I’d like to install a toilet with macerators. Does any of these Domestic models suit me?
Marcus Robertson
Hi, Linus! Thank you very much for your question! These Dometic toilet models compared in the review belong to standard gravity toilets. They do not offer macerators. That’s why if you’d like a system with macerators only for your RV, Dometic 310 and 320 will not suit you. Please try other Dometic toilet models like MasterFlush series.

My hasband is a grand man of almost 300 pounds. Honestly, toilets seem to be too fragile to deal with 300-350 pounds as you said) I’d like to hear real users’ stories, so if anyone tried such things, please share. P.S. Great comparison, Marcus!
Marcus Robertson
Hi, LilaCru! Thank you very much for your question! Indeed, the toilets are that solid) However, we’d also be very glad to hear other users’ experience.
