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. The low-profile design means it'll take up less space in your RV's bathroom. 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 321 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.

This RV toilet works great in our 2015 Minnie Winnie.



by:

AS usual, working with etrailer was a breeze and the shipment went out right away. When the original shipment arrived broken, a quick phone call had a replacement on its way to us and it arrived in two days. Fantastic customer service!



by:

I originally purchased this exact same toilet from etrailer and sadly it broke a few months after the warranty. Sadly, there isn’t a replacement part. The “ball flap” that closes and opens when you depress the foot pedal broke so that the flap no longer would open or close. This is literally the only short toilet with elongated bowl that I can find.

I requested etrailer to discount this second toilet but they couldn’t do that because it was out of warranty. The toilet is nice and comfortable but hoping if it breaks this time, it does so within the two year warranty otherwise it’s going to get really expensive. I will say that we absolutely love the toilet while it worked.

One note - the new toilet came with a cracked seat.

Shoot! I am sorry it came cracked! I already sent your information to our customer service team and they will reach out to you about this.



by:

I like the toilet but it doesn't hold water anymore.



by:

This is a great unit! The big full-sized elongated ceramic bowl is far more comfortable than the rounder type.
Service was excellent and fast!



by:

This was a good compromise between the cheap, shallow toilet originally installed and the the tall but deeper model. Because the toilet mount sets about 5 inches above the floor level this one worked best. Installation was simple enough. The flush pedal is above the floor mounting stud and is a bit hard to see, so tightening the nut is done by feel.



by:

Swap out was very simple. This is far better than the plastic crap (pun intended) that was in my RV before. Time will tell as far as durability. So far so good.



by:

Don't like water fill with downward pressure, too easy to flush accidentally. Wish we'd gotten with water rinse spray. Had to change angle to fit corner of WC. Actual performance has been flawless! No cleaning of toilet seal, no leaks in unit. Some leaking around base but installer afraid to tighten too much. Requires some cleanup.



by:

Ordered this Series 321 as a replacement from one that had broken on me. Specifically, the ball valve had snapped, where the plastic nodule pivots against the pedal assembly. Etrailer was responsive to my emails, especially when the product showed back order due to manufacturer. Arrived intact and MUCH earlier than originally anticipated. Toilet is quality for price point. Etrailer, as always, are professionals and wonderful to deal with.



by:

You guys five star rating! UPS not was suppose to be delivered on Friday and was not , it sat in Columbus for 14 hours! Got on Monday and was delivered to wrong hose on street! I have address on mail box and front door, and both sides of the house on each corner! So how he got it there who knows!!! But you guys fine you let me know what was going on!!!!!!

by:

Great quality and worked perfectly for my RV. The ceramic bowl is residential quality. eTrailer (as usual) had a great price and very fast shipping.



by:

It's as advertised! Happy with my purch ase.



by:

Good toilet, but should come with a sprayer. Who doesn’t want a sprayer?



by:

So far so good. The delivery was fast and I installed it two days ago and it's working great. It was so easy to install. It feels sturdy and like it will work well for us as full timers.



by:

Came just as it was ordered can’t wait to try it out

Easily installed.

Low profile means

It’s been around a year and has turned out to be a great product. Easy to install, great quality product with zero issues. Just like using trailer, great prices, zero ordering issues with great support whenever I had any questions.

  • Replacement RV Toilet Options With An Elongated Bowl And Hand Sprayer
    Hey Karen, We offer a few different options with elongated bowls but they unfortunately don't come with the hand sprayer already installed.

    For a 10 inch rough in dimensions we only have low profile toilets that fit like with the Dometic 311 Part Timer part # DOM67FR. To use a toilet like the Full Timer part # DOM87FR you'd probably have to modify the wall behind the toilet to allow the additional inch.

  • Recommended Replacement Options For A Dometic 111 RV Toilet On An 8" Tall Platform
    Not every RV has a platform for the toilet so it's a bit of a case by case situation. The biggest fitment factor is the rough-in measurement, which is the distance from the wall behind to the toilet to the center of the flange bolts. Dometic recommends an 11" rough-in for the 111 model so we have the following low profile options that can fit this rough-in: Dometic 311 Part-Timer RV Toilet - Low Profile - Round Bowl - Slow Close Lid - Tan Ceramic # DOM77FR (15-1/2" Tall) Dometic 311 Part-Timer...

  • Could Dometic Full Timer Toilet Replace Traveler in RV
    It's not so much the dimensions of the Dometic 4310 you'd need to compare to determine if you have room for a different toilet so much as it is how much room is available in the bathroom. The overall dimensions of the part # DOM99FR are 22-1/4" long x 14-3/4" wide x 16" tall. You'd need to compare that to what room you have now to see if it would fit.

  • Is Dometic 321 Full-Timer RV Toilet a Good Choice for a Wet Bath
    The Dometic 321 Full-Timer RV Toilet # DOM99FR has a ceramic bowl that will be okay in a wet bath but the seat is wood which will eventually need to be replaced if it's going to be hit with water fairly often. If the toilet is far enough away from the shower then you might be okay but the Dometic 300 Weekender RV Toilet # DOM74FR would ultimately last longer since the bowl, seat, and base are made of a lightweight polypropylene (hard plastic).
