Perfect for Full-Time RV Living

Living in an RV while exploring the country is a real adventure, and you'll want your facilities to live up to that lifestyle. This RV toilet easily handles everyday use, making it great for when you're living in your RV full-time. It's just as tall as a standard residential toilet, so it's easy to sit down on and get up from. The durable wooden seat holds heat for those chilly nights. And the sturdy ceramic bowl is easy to clean. If you call your RV your home, this is the toilet you'll need when nature calls.

Measure to Fit

RV toilet rough in measurement

There's one measurement you should double check to see if this toilet will easily fit into your bathroom. The rough-in measurement is the minimum distance you'll need from the wall to the center of the flange on which the toilet will sit. To measure this distance without uninstalling your current toilet, the mounting bolts on the side will typically tell you where the center of the flange is. You may want to triple check if your toilet has an offset flange or 4-bolt mounting style.

The Dometic 320 Series RV toilet has a rough-in measurement of 11". If your rough-in measurement is less than 11", select a toilet model with a lower requirement or consider alterations to make it fit. Keep in mind the overall dimensions of the toilet, and measure for yourself to pick the best model for an easy DIY upgrade.

Perfect for full-time adventurers, this durable, standard-height RV toilet can handle everyday use. Elongated design provides plenty of comfort. Sturdy ceramic bowl is easy to clean. Each flush uses just 1 pint of water.


Toilet arrived timely. Everything is in good condition. Easy installation despite close tolerances (went from stinky plastic 300 Dometic model to 320 with a porcelain bowl. 300 model was only 2 years old with minimal use and septic was leaking between the bowl inner & outer cases. Sorry etrailer but the Dometic 300 models should not be sold, they are a sanitary hazard even for occasional use. Anyways back to 320 model, simple and easy to install. Chasing the mounting bolts in mounting plate slots gave me some exciting competition but I prevailed. Highly recommend this model.


Much nicer than cheap plastic toilet installed as original equipment that leaked between bowl & outer shell, smelled worse than an outhouse. It's a little bit longer & just touches back wall, but should be ok. Feels more sturdy & comfortable with the wooden oval seat. Just winterized, so I'll find out for sure next summer. 2018 Wolfpack 325P13 front bathroom.


really nice. converting a skoolie and all my research pointed to the 320. installed but not used but seems like a great elongated porcelain toilet. fyi the pedestal is plastic but I guess that's the norm. also it is white but even on the box it says off white so no super bright white but I don't think I'll care.


Switched out our Dometic 310 to a 320 full timer toilet with an elongated seat. Very easy to switch them out. Flush is so much better. The seat isn’t the greatest, as the finish isn’t done well. Planning to switch it out for a slow close. E Trailer ordering and shipping was fantastic.


We replaced our 310 with the elongated 320... I like the flush using less water. We moved the hand sprayer over from the 310 as well without issue. My wife likes it much better... it is the Cadillac of RV toilets.


I was replacing a Dometic with a standard round bowl with a Dometic elongated bowl. The swap was super easy. Turn the water off, unscrew the water supply connection, remove two nuts holding the toilet down and remove the toilet. Replace the bolts, set the new toilet in place, install and tighten the nuts, reconnect the water supply, bodda-bing, done. The only other thing I did was replace the Dometic lid and seat with a slow close, quick release lid and seat. It is a lot easier to clean if you can quickly unlatch and remove the lid-seat assembly.


Excellent experience with etrailer. The Dometic 320 was purchased to replace a Dometic 310, It was a perfect fit. The best price was etrailer. The packaging and delivery was excellent, arrived undamaged and on early. Would recommend etrailer to anyone. Thank You.


Replaced a round Thetford Aqua Magic toilet that was a PITA to keep functioning properly and to service. Also, we hated the plastic kid on the Thetford, with all the nooks and corners, that was difficult to clean; this one has flat surfaces that are easy to clean. This one is WAY more comfortable, sturdy, easier to maintain, and functions better. Had no problem installing it; 15 minutes, start to finish. Glad we made the change; we are full-timers, and this serves our needs better.


Arrived a day earlier than expected, which is always a plus! Much better than the dometic 300 but only complaint would be that the base is more of an off white versus the Brite white of the porcelain bowl. All in all, no complaints. Now let's see how it does over the next 6 months.


Replaced a Thetford toilet in our new motorhome . Easy job . About one hour with taking my time .

Good upgrade, wife is happy.

etrailer was fantastic as usual couldn't be happier. Unfortunately my ball valve seal is leaking right out of the box unfortunately quality standards or a lack there of seem to plague the RV industry as a whole I purchased another seal and we'll get with Dometic for a refund.


This toilet is a great height and the seat is a great size, and the bowl is easily cleaned given it's porcelain like a residential toilet. The caveat is that the area between the dump and the flange does capture a lot of waste and needs to also be cleaned - which is not an easy task.


Have had this toilet for six months, and it's done well. I like the feel of a regular toilet and not some cheap plastic one. The one negative was that the seal at the bottom of the bowl where the waste goes down when you push the petal will go through 1-2 week spurts where it doesn't seal off and hold a little water in the bottom. But that's really the only complaint.


The size of the elognated bowl is awesome! The porcelain elognated bowl is the only way to go when you got to go! I'm a pretty big guy and worried that I would snap the old plastic 300 Dometic off the floor every time I used it... This 320 full-timer feels nice and sturdy... Gave it 4 stars because after installing it I realized that it was not holding water that well. I followed the instructions on what to do... I stuck my hand down there, stretchd the seal out, poured hot water in the bowl, & waited till it got cold. This did the trick as it seems to be holding water just fine now... Overall it's a really good product and I would recommend it to anybody that has a plastic one to upgrade to the 320 with the elongated porcelain bowl!


VERY fast shipping (excellent tracking info).
Installed w/i one hour of delivery.
Works perfectly.


This was a replacement for a different brand. It has worked flawlessly. We switched to this unit because of the ability to change the seal without having to remove the unit from the floor. The experience with etrailer was, as always, excellent.


Very happy with it. Works better then expected. Was damaaged when shipped ( from postal service, not company). They offered to replace it for free and ship it free, but I was able to repair and it works great. Am considering getting another one for camper.


Nice to have a "real" toilet. This is the second toilet etrailer sent us. The first one got broken in transit. etrailer handled the replacement well. I was very appreciative of their customer service.
Love this today!


Upgraded the small plastic toilet that came in my Stryker 2916 and also added a Tushy Bidet. Works great and big enough for an adult now.


I never thought I would be so happy to upgrade a toilet…we had a Thetford Aqua Magic II, which we had noth8ng but problems with (I replaced the valve twice, overflowed multiple times). This Dometic toilet just feels better quality all around.


Great service from Joshua at E-Trailer.
Note to buyers: make sure your bathroom door swing will clear the toilet bowl…it’s longer than the std. bowl.


Pros (not many): Feels like a "regular" toilet in height and size. Cons: The 360 flush is useless because of the low flow function. Make sure you get the spray hose or have a bucket ready to rinse the bowl. The pedal contraption that opens the flap gets dirty and smelly and is a pain to clean. The residential seat is too vented allowing odors to escape when you flush. Regret making this purchase and one day when I get fed up with it I'll go back to a more standard RV toilet like we had.


Well , I’m very disappointed with the knowledge you had. This toilet is a two bolt system and was told it was a 4 bolt. You site even said I need the adapter to go to a four bolt so I ordered an adapter that I didn’t need. Then the adapter was out of stock so you held my
Order up for three weeks waiting on the part to come in that I didn’t

I apologize for any misinformation that was provided. This toilet does have a 2-Bolt installation fits most existing floor flanges. I will have our customer service team reach out to you.
