Ideal for Part-Time RVers

When you're taking your RV on the road for weeks at a time, you'll want to make sure your toilet can handle that long a journey. This toilet is built for part-time RVers who use their RV more frequently than just on the weekends. It's just as tall as a standard residential toilet, so it's easy to sit down on and get up from. The ceramic bowl is more durable and easier to clean than a plastic bowl. And the lid closes slowly, so it won't loudly slam against the rim. This toilet provides the durability and ease of use needed for your long RV adventures.


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 310 Series RV toilet has a rough-in measurement of 10". If your rough-in measurement is less than 10", 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.

Huge improvement! We purchased this to replace a Dometic 300. We could not locate the foul smell in our RV until we learned that it was the 300 had a defective gasket! Instead of replacing it, we ordered the 310.
No more smell! The 300 had a lot of nasty "liquid" in it!
The 310 is so much nicer, we love the slow-close lid and porcelain bowl.
Installation took 10 minutes! Thank you, E-trailer!

It is still working great. We are very happy that we upgraded to it.



by:

It arrived missing one of the seat hinge nuts. It took a lot of push but etrailer came through sending me via Dometic the part that was missing. We had a professional install the toilet along with other updates. It appears to be work fine. We have not actually sat & used it. The RV is still in refurbishing & upgrading. But we did flush the black tank out and ran a flushing wand through the toilet to help that event. It appears to be sealed. My husband does not like the quite soft closing lids. He would rather have them more regular fair. It's not his RV it's a SHE model and SHE loves the toilet & Miss Mini MO loves her new upgraded toilet and MaxAir Dome Exhaust Fan & bathroom sink faucet all from etrailer too. Hoping to have her road ready by mid June.

@Kirk That's great to hear! Thanks for the feedback!


by:

Toilet was well packaged. It is as described. However I was surprised that no paperwork came with it — no installation instructions, no warranty info, and no manual.



by:

Came quickly and fairly easy to install - a little hard to get the mounting bolts to stay in one place when mounting but got it in place. Another great service from etrailer!



by:

Works great. Easy to install. Had a Dometic 300 and would leak. This one seems a tad taller also.



by:

I purchased this toilet one year ago. I installed it myself after watching a you tube video. I had a little trouble with the rubber gasket that seals water in the toilet. I needed to get a new rubber gasket, but other than that the toilet works great, and I love the slow close lid. I believe it is lighter than the factory toilet so that helps with additional weight in the RV.



by:

Shipping only took a day but ups broke the first one. It was promptly replaced and easily installed, took about 10 mins. Did away with all the squeaky night time potty visits. We are much happier with this toilet that replaced the 300 series.



by:

The product looks amazing. I haven't actually tried it yet, but the installation went seamlessly. E-trailer has been my go to place for trailer parts.



by:

We love everything about this toilet except the flush valve seal ring. When I installed the toilet the ring didn’t seal; it would not hold water despite my doing everything Dometic recommended for a new install. Etrailer sent me a new seal ring, and that worked, for a few months. Then it would not hold water again, so I replaced it again. I’ve replaced it one more time since, and I carry spare seals now. It’s an easy fix, but annoying to have to deal with. Clearly the seal is not designed and/manufactured correctly. In spite of the issue, I still like the toilet, and etrailer was easy to work with on the 1st seal replacement.



by:

The toilet (310 model) in our 5th wheel needed to be replaced after 7 years. I found exactly what I needed at a great price. Shipping was quick and I already have the new toilet in and it is perfect.



by:

This toilet will not hold water since I purchased. I've taken the gasket out and cleaned the flapper, gasket and bowl where it is inserted several times. Can you send me a gasket replacement

I reached out to the manufacturer and they advised it does sound like it needs repairs. I will send you the link to their website that can show you repair centers that are close to you.



by:

Great product. I'm a Mobile RV Tech and I've installed many of these Dometic 310 toilets for my customers as well as my own RV. E-trailer gets it there quick and the product works great.



by:

This toilet is so much studier than the cheaply made 300 series one that came in my 2019 Springdale travel trailer that leak between seals and smelled



by:

Only needed 1 simple change to the existing plumbing and it fits perfectly.

Great! Foot flush is much easier for us older folks. Easier to dump buckets when flushing the tanks.

@Steven That's great to hear. Glad to hear you have something to go on...


by:

Easy upgrade, definitely worth it!



by:

It was easy to install but I wish the base design was a bit different. It is really difficult to see the base floor bolts in order to loosen or tighten them. Other than that, I love the toilet. The soft close lid makes me laugh because any little vibration will set the close feature. I prefer to think that it is a MAJIC lid!



by:

Fast prompt shipping. Easy company to work with.



by:

Great toilet, just wish the elongated bowl (320 series, I think) would have fit. The 310 feels solid, much better than the plastic factory model.



by:

Really happy with this toilet. My last Dometic toilet leaked and smelled really bad as it was a two piece toilet and allowed waste to leak into the hollow parts of the toilet. This does not have the same design and has bee solid, feels much better (sturdier) than a plastic unit and good height. This is a must do if you have the older 300 series units.



by:

The Dometic 310 toilet replaced the Thetford toilet in our 2011 fifth wheel. I like that the water flushes from all around the top of the rim instead of just the back. Keeps the bowl much cleaner. When it's time to change the ball seal we can do that from the top of the bowl instead of having to remove the whole toilet to replace the seal. A great upgrade.



by:

Previously had the all plastic bowl, the 310 with both seats being soft close is pretty fancy stuff. You sit slightly higher which is more comfortable. Good product altogether, I would recommend this model RV toilet



by:

The toilet is taller than a regular RV toilet and it is made a lot better. I would buy this unit again.



by:

much better than the stinky 300. I like the slow closing lid and the stability of the 310.



by:

Replaced an older Dometic toilet. This one only took about 15 minutes to install and works great. Shipping was fast by UPS and product arrived in excellent condition.

  • Recommended Replacement for Dometic Traveler Lite 111
    There is not a tremendous difference between the Dometic 320 Full-Timer RV Toilet, # DOM87FR and the Dometic 310 Part-Timer, # DOM57FR. Both have a ceramic bowl and constructed to a standard height similar to what is found in most residential houses. I recommend the Dometic 320 Full-Timer RV Toilet, # DOM87FR because of its elongated design over the round bowl design of the 310 Part-Timer, # DOM57FR. The Dometic 320 Full-Timer RV Toilet, # DOM87FR also has an enclosed rim that keeps...

  • Are Any Parts Not Included With The New Dometic Part-Timer RV Toilet Needed For Installation?
    The Dometic Part-Timer RV Toilet - Standard Height - Round Bowl - Slow Close Lid - White Ceramic # DOM57FR comes with the new mounting hardware and new seal so there is nothing else required for installation. Your current water line should connect right up as long as it is in good working condition.

  • What is the Difference Between the Dometic 310 RV Toilet and Dometic 311 RV Toilet
    The main difference between the Dometic 310 Part-Timer RV Toilet # DOM57FR and the Dometic 311 Part-Timer RV Toilet # DOM67FR is that the 310 is standard height (20" tall) and the 311 is a low profile (15-1/2" tall). Both toilets will mount the same and have predominantly the same features. There are a few other small measurement difference but none as big as the height difference. 310 Measurements: Overall dimensions: 18-1/2" long x 15" wide x 20" tall Seat length: 15-1/4" Seat thickness:...

  • Can a Dometic 310 Toilet Be Used In Place Of a Dometic 300?
    In my experience you are only going to be able to get the Dometic 310 Part-Timer RV Toilet # DOM57FR to fit if you have at least 10" from the wall to the center of the toilet flange. With you only having a 9" rough in it is going to limit you to the Dometic 300 # DOM64FR. There is one situation where I have seen a toilet fit and that involved turning the unit sideways but again you will have to ensure you have the rough in clearance to the side as well as either a 4 post toilet flange...

  • Will the Dometic Part-Timer RV Toilet 310 Series Replace a 300 Series
    The Dometic Part-Timer RV Toilet (310 Series) part # DOM57FR should be a direct replacement for a 300 Series Dometic Toilet. I took a look at some reviews and many have done this stating it was pretty much plug-in-play with only slight modifications. I don't have any dimensions on the water inlet height unfortunately though.

    Your flush ball on the Dometic 300 Weekender RV Toilet # DOM64FR is different from most toilets.

  • Can Sprayer Be Added to Dometic Part-Time RV Toilet

  • Water Inlet Fitting Size For Dometic 310 Part-Timer RV Toilets
    The Dometic 310 Part-Timer RV Toilet # DOM57FR water inlet is a 1/2" NPT fitting. You should be able to easily find a tee to connect to the water supply line and water inlet on the toilet, just make sure you determine the bidet's fitting size before you go get a tee and find out it's the wrong size.

  • Recommended Replacement For A Sealand 111 RV Toilet
    From what I can find the rough-in for your Sealand 111 RV Toilet is 10" so the Dometic 310 Part-Timer RV Toilet - Standard Height # DOM57FR you were looking at would be a compatible replacement. I just recommend doublechecking the measurement from the flange bolts back to the wall to ensure that you have a 10" rough-in before purchasing. I've attached a short video below where I'll walk you through the installation process.

If your flange is glued to the pipe then you would need to cut it off and will most likely just have a 3" pipe sticking up to connect to. In this scenario you would use part # 344633633, which has...
