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.

Overall, this is an excellent toilet. A great replacement for an older worn out ceramic, and a fantastic upgrade from any of the plastic models out there. Well manufactured with good water flow and a sturdy foot flush pedal. I installed this toilet in March 2022 and have had no issues at all with any leaks. The water feed is well made and secured, as well as the flush mechanism. My one complaint is that the seat/lid paint seems a bit weak as the seat has a couple unexplained chips in it and the lid paint is wearing off where it touches the wall when the lid is up. But seats are fairly easy to replace so it's not major issue.

As an aside (that I hope etrailer allows me to mention because I intend to commend them) my toilet arrived damaged. It was an "emergency" purchase as the plastic toilet I was replacing had sprung a major leak, literally cups every few hours. I've included a couple pics of the damage. Since it was still usable, and I'd already taken out the leaky toilet, which further damaged the area it was leaking from, I elected to repair and install the new toilet. I then contacted etrailer to let them know what had happened and they replied that they would have replaced the toilet entirely, even though the damage was minor. What's more, they offered to reimburse me the cost of the repair materials! As it was a few cents worth of Liquid Nails I felt reimbursement wasn't necessary, but as a result of this interaction etrailer has gained a customer for as long as I'm living in an RV :D


The new toilet came ahead of schedule and Sheryl H. was super helpful and made sure it arrived on time. The box came in good shape and everything was in place and arrived safe and sound. This toilet was a very tight fit in my installation but I was ready to modify the cabinet behind if needed, but it just fit. Very well made unit and seems to work well so far and no leaks. The original plastic model 300 was working fine but did not like the plastic. The new model 320 is just great ! Sheryl H and etrailer was just perfect. Great customer service and support. I will continue to be a loyal customer.


Received our new Dometic 320 toilet for our 5th wheel RV. Took out the old one and installed the new all in about 30 minutes. Looks great and works way better than our old one.


I am a 61 year old woman and I installed this toilet my myself. The videos on here and on [online] were very helpful. I love it and I hope to continue loving it for years to come.


I replaced a high profile Thetford Aqua-Magic which was 8 years old and original equipment in my toy hauler. The seal in the bowl was leaking so first I tried to replace the gasket and that did not fix it. This Dometic 320 is a bit larger and about 1/2" higher, but it fit. The first toilet I received was broken in pieces. It even had the word "BROKEN" written on top of the sealed box when I received it. I suspect it was shipped that way and didn't break during shipment. I contacted Amy J. at and sent pictures of the demolished toilet. She quickly approved a new one to be shipped and sent instructions on return of the broken one. I simply boxed it up and UPS came by and picked it up. The Dometic piping arrangement did not match the original installation so I easily installed a 1/2" Shark Bite X 1/2" MIP adapter on the 1/2" PEX water supply. The connection to the toilet is 1/2" MIP. Therefore, I got a long (18" to 24") flexible stainless steel "supply tube" with 1/2" FIP connections on both ends to finish the water supply. All of these fittings are available in the plumbing department of Home Depot. You may have to look intently for the "supply tube" with the 1/2" FIP connections, but they are available. While I was satisfied with my Thetford unit before the bowl seal failed this Dometic is clearly a superior unit and I am extremely happy with


Fast delivery and great product!

Great upgrade!

This should be an option for any RV, etrailer had it at a great price. It took less than a week to be shipped to my home. I removed and installed the new toilet in less than a 1/2 hour.


Arrived in good condition. etrailer representatives were professional. Will install at a later date.

Installed the Dometic toilet in our motorhome and have used it for 6 months. Installation was easy and have had no problems since the install. The toilet is an improvement over the old toilet and we are happy to have made the change.

etrailer’s customer service was amazing. I live in my camper full time. So when my (2nd) Dometic 300 series toilet within 3 years quit working, I was eyeballing the woods next to me for cutting a trail! Lol! Everywhere I looked for a Dometic 310 w/ceramic bowl was either back ordered or had an insane price tag. Found etrailer online, not only did they have the toilet I was looking for at a very good price but also had so many hard to find camper accessories too. I ordered a Dometic 310 but would take a little after Thanksgiving to get. Emily reached out to me and explained other options that could be shipped immediately. I decided on a Dometic 320 and had it within 2 days. First toilet I have ever installed by myself…took me about an hour but no leaks so far. Thank you Lord!!!! Thank you! Highly recommend the Dometic 320 & recommend etrailer….check them out!


this is the BEST price i found for the 320 dometic toilet, fast shipping, GREAT customer service, i will definetly buy from e trailer again. thanks john


We love this elongated porcelain toilet. An excellent upgrade for our 21FBS camping trailer.


The best RV toilet I’ve owned!


I have used etrailer multiple times. Excellent customer service good pricing and timely delivery’s. What impresses me the most is their product knowledge and product information.


We love our new toilet. It's wonderful to have a full size seat in our outhouse. And the foot flush is smooth and at just the right position.

A year in and we are still very happy with our toilet. Its sturdy and easy to clean.

I installed the Dometic 320 about a year ago. Couldn't be happier. (Never thought I'd say that about a toilet!) The large size is much more comfortable compared to the small oem toilet that came with my Greyhawk. A+!


The toilet got here within 2 days and I couldn’t be more happy with it. Installation was a piece of cake and the bowl is real porcelain , a big upgrade from our previous plastic one.


I have been very satisfied with the service i received every time i contacted etrailer on this project of replacing a Dometic 110 with a Dometic 320 and adding a Dometic Vacuum Breaker - Hand Sprayer Kit. Vicki was very helpful in getting it ordered the way i wanted it. It was recomended that i go with a Model 510 because my 110 had a hand sprayer kit and the 510 came with a hand sprayer kit. In checking the measurements of the 510 vs the 320, i found the 320 to have an elongated seat and toilet bowl hole. So Vicki ordered me a Model 320 with a hand sprayer kit which was actually cheaper than the Model 510. I installed it myself in a 2003 Carriage Cameo 5t Wheel. As you can see by the pictures i have added, with 110 i took out, the water line hooked up on the left side of the toilet and the 320 water line hooked up on the right side. I was able to twist the pipe toward the right instead of the left. so then, after the second trip to Lowes, i was able to get a pix shut off valve (which i didn't have before) and a 12" flex line to hook it up. Flex line would have been better if it was a 6" line. The old toilet was very simple to take out and new one very easy to install. I spent the most time figuring the water line out. The only thing that i thought was confusing was the toilet descriptions online. The measurements were listed a different way on the 320 vs the 510. This made it hard to compare the two. My wife is very happy with it, and when camping, a HAPPY WIFE is a GOOD THING!


I was looking for a normal size toilet for my rv. This is a great replacement quality is good and the price was cheaper than I could get from my local rv dealer. Had to do a little changing to the water supply line but it was an easy install less than 20 mins. This toilet requires at least 11” from flange bolt to the wall. If your looking for a nice full size toilet for your rv this one is a great toilet.


This was a replacement for our 2018 Grand Design Solitude 377MBR.

This toilet is very comfortable and is an appreciated upgrade from the standard round front toilet that came with my RV. The back of the toilet fits closely to the wall and looks much cleaner than the Thetford that was originally installed. After my wife used the toilet she said "wow now we have a real toilet". I am very pleased with this product.

I was worried that the new elongated toilet would drastically reduce the free space in the bathroom but we still have 18" of space between the toilet bowl and cabinet in front of it. It did not have the drastic impact we thought it would. It is funny what we think a lot of space is now.

This being a replacement caused a bit of a challenge, the original had a very high water connection in the center, this toilet had a very low connection near the right side of the base. Making the connection required a bit of reconfiguration of the water pipe. I used a couple of 90s to get things to line up. There was a water shut-off valve just for the toilet which was installed by the previous owner which made working on the toilet a little easier, without the shutoff I may have been able to make the connection without issue.


We purchased the Dometic 320 RV Toilet and installed it in our 2018 River which worked very well except we needed an offset flange to enable is longer at the back. We sure have enjoyed this elongated toilet, it operates very well and looks great.


Toilet in the rv failed and replacement wasn't available locally. Odelia at etrailer was so helpful and got a dometic 320 sent 2nd day, it arrived on time and in perfect condition. It installed in minutes and works great,happy camper


Nice toilet, although it would be nice to have a slow close seat on a nice high end product like this.


Really wish they came with soft close lids. Or atleast have hinges available that are soft close


Perfect transaction!!! Shipment was right on time. Definitely the lowest price out there!!!


Great quality, delivered fast. Thank you
