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.


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


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.


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!


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+!


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.


This review can only cover order & shipping. Ordering was extremely easy (after I verified "eTrailer" as a legit site). The product arrived in the quoted window of shipping time. When I picked up the unit from UPS store, I heard things rattling around and assumed it was just parts. Opened box with installer here and discovered the "parts" were pieces of porcelain. So a replacement is on the way - and this process was also seamless! Pleasure doing business with eTrailer so far!


It was what it was surpost to be. Fight shipment was damaged. etrailer shipped a replacement in a timely fashion.


Fast delivery and great product!


I am Happy with the Toilet as it is more to my liking. Have the old one which was used for a short few months, to Market no need for it now.


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


Easy to install Bigger is better. One year still perfect.


easy to order, was delivered on time and what we ordered,

    You can replace your current Dometic 300 with the Dometic Full-Timer RV Toilet # DOM27FR ( # DOM87FR for white) if you like the elongated bowl design or you can replace it with a Dometic Part-Timer RV Toilet # DOM57FR if you just want another standard bowl design.

  • Are Mounting Bolts Same Spacing When Replacing Dometic 300 With Dometic 320 Toilet
    They sure are! The mounting hole spacing is going to be the same from your Dometic 300 Series toilet to the 320 Series toilet so you can absolutely use the 320 Series, and it will fit the same flange/water supply line as the 300 Series. You simply need to ensure you have 11 inches from the flange mounting bolts to the wall to have the necessary clearance to install the 320 Series. If so, there are two options, depending on the color you want: - White: Dometic Full-Timer RV Toilet # DOM87FR -...

  • How to Add Battery to Utility Trailer to Power Lights
    To protect the battery and prevent theft you'd want to use a battery box like the Torklift part # TLA7720R which you can mount on the a-frame or in the trailer. Then from there you'd want to run the 12 volt accessory circuit of your 7-way to the positive post with 10 gauge wire like # 10-1-1 and run your lights directly from the battery terminals. We also have a version of this box with a solar panel with part # TLA7720RS.
