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.


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.


Price, delivery, and the product were excellent! The ceramic toilet is a great upgrade to our travel trailer with only a slight increase in weight (about 30lbs.) I would recommend as well as the Dometic 320 to anyone interested in an upgrade to their RV.


The Dometic 320 Elongated Toilet was excellent right out of the box, perfect replacement for thr 310 model our trailer came with. Being 6’3” and about 250lbs, I needed a bit bigger throne and the 320 was perfect.
Installation was about 10 minutes from box to leak check, two 7/16 nuts and a waterline attachment and your done, unit comes with new compression seal installed.


I installed the toilet myself which went well. After one year of full time use of the Dometic 320 I can say it works well and we haven't had any trouble with the unit.


Why would you want a lesser toilet? This one has been fabulous, not a cheap item but a quality one like unto residential toilet you would expect. Well worth the easy change out. Sold the original brand new toilet that came with our Cougar RV with ease and good riddance. Highly recommend this toilet 2nd to none.


Lightweight for being ceramic. Easy to clean and quieter than the old one when flushing. The flushing mechanism is far superior to the old cable system. The water flushes around the whole bowl for a cleaner flush. Very pleased and making plans to replace the plastic toilet in the bunkhouse end of our RV.


Just what my husband wanted. Extremely easy installation. I am an almost 70 year old female & I had no issues installing this by myself.


This is a warranty replacement order for my original order that arrived with a defective flapper valve which was required to be returned at my UPS expense of $XXX.XX. Fortunately, this replacement order arrived with no defects. I am still disappointed with the manufacturer's "DOMETIC" (unethical) return policy for a (unused) defective product at the customer's expense. Buyers beware


As usual, as expected, ETRAILER came through, no question asked!
Great customer service, GREAT quality products, Thank you ETRAILER!

etrailer had what I couldn't find anywhere else. They shipped it for free, arrived undamaged and 1 day early.


Very happy with this toilet. Didn’t take up much more space and the elongated seat is much more comfortable. Shipping was extremely fast. Great service.


Nice toilet large enough to be comfortable. The only thing is the base plate is two bolt and my old unit was four bolt, had to do some modification to fit but it worked. Also the old unit was left foot flush and this is right, again had to do some water line plumbing. Very nice aside from the replumb, fit perfect to the wall.


Great rv toilet and good price.


The box arrived in perfect condition and toilet undamaged. However the ceramic bowl drain was off center 1/4 inch to the flapper valve assembly. Had to loosen the 4 screws/bolts holding them together and realign and tighten the screws. Hope it stays in place with no future problems or leaks


Great toilet! The quality and design is excellent for an RV toilet. My only complaint is the toilet lid opening too far - easy fix though. Thank you etrailer! You guys rule!


etrailer comes thru again. There was only 1 in stock and I needed 2. They were not going to arrive in time if waiting for both so I called and asked them to split the order so I would have 1 in time for our trip. They said no problem, it will go out today. Guess what, they shipped them both!!! Installed both toilets this morning, they are awesome. One note of caution. These toilets have a 1" longer rough in from the wall to the flange. One of my toilets was tight against the wall so I had to cut the wall to accept the extra 1". Looks great though.


When the product arrived the base was broken and the box had obviously been opened and re-packaged because part of the hardware was missing.

I will have Customer Service reach out to you about the damage.

We've used this toilet for our double decker bus conversion. We wanted a good product that feels more like a home and not a RV. The porcelain makes a big difference, and adds to the homeyness feel of our bus. It's easy to clean too.


I had 2 dometic 300 series in my RV in the last 6 months had a problem getting waste water between outer shell and bowl I live in my RV full time so I saw this one and decided to give it a try very very happy with this toilet you don't get the squeaking and groaning noises when you sit down or move around and it flushes very quiet.just what you need if your a full time RVer great service from etrailer


Excellent toilet, very well priced and fast delivery to our RV site with no damaged.
Fits perfectly in our Grand Design 320x
Our measurements from the back wall was 10 3/4
Very impressed with the service when we called to order it

Easy to order. We installed it ourselves with no problems. The item came quickly.


This was the first of many purchases to come from The staff was very helpful and got the order shipped out the same day. The Demetic 320 was a perfect fit and replaced my old Aqua Magic IV. Thanks etrailer.coming
