Dometic is noted for producing elegant plumbing goods that are designed to maximize comfort and economy. First of all, the brand is famous among travelers and camp fans as it provides excellent RV toilets. They are one of their best products in terms of water saving and compact design.
That’s why in this article, we decided to compare two best-selling models, Dometic 310 vs 320. The convenience of use, improved hygiene, and…some complaints. Why? And do pros redeem drawbacks? Let’s find it out!
Main Differences Between the Models
The models are very similar both in appearance and construction since the 320 series became an upgraded version of the 310 model. However, we noticed the following crucial differences:
- Dometic 310 has a round bowl, while the 320 series received an elongated and deeper bowl.
- Due to the rim in Dometic 320 toilet, users are safe from spills and frequent floor cleaning. Dometic 310 doesn’t offer a rim.
- The first model is equipped with a slow-close enameled wood seat. The second toilet features a full-size residential style wood seat.
- Dometic 320 is a bigger and heavier RV toilet.

Dometic 310 series toilets are distinguished by the compact design. This modification requires little space for installation, saves water, and at the same time feels very convenient for use and cleaning. The model comes in two size options – you can choose between low profile and standard height. We took the standard product for review.
The toilet features a nice slow-close enameled wood seat. Flushing is exceptionally hygienic as you don’t have to press any buttons and touch the toilet with your hands. Just press a foot pedal. The 310 model additionally comes with a hand spray.
Flushing will take no more than a pint of water. Such an economy is possible, thanks to the well-thought-out bowl design and swirl-jet action. However, please mind that spills are frequent as we have no rim.
Dometic 310 will perfectly fit all types of recreational vehicles, including motorhomes, campervans, camper trailers, truck campers, etc. Many purchase it even for their small bathrooms. It’s an excellent saving option that has almost no drawbacks. Besides, the price is more than affordable for a ceramic toilet.
- compact yet convenient
- has two size and color designs
- foot pedal flushing contributes to the hygiene
- so does the hand spray included
- only one pint per flushing
- slow-close enameled wood seat
- easy cleaned
- easy installation
- affordable model
- no rim causes often spill
- the base part is not that solid
- the manufacturer has serious issues with packing, so many customers complain about broken products
Dometic 320 came to replace the previous 310 series. This toilet saved the core but added certain improvements, the most important of which are a changed bowl shape and rim.
The manufacturer calls it an elongated model. We got an oblong shape and deeper bowl for greater convenience. In general, the product became bigger and heavier, so be ready to provide more space for installation. Once again, there are a standard height and a low profile option.
Efficient water flushing is preserved, though the top was complemented with a rim. Engineers hid the flush pattern under the rim, which solved the problem of spills. Consequently, now the product boasts a full-size residential style wood seat.
At the same time, users received other beloved features such as an ergonomic foot pedal, one-pint flushing, and a hand spray.
The model will become a decent alternative to the 310 series. However, bigger dimensions may not suit some campers, so please mind it before purchasing. Otherwise, we love its improved design.
- still quite compact
- has two size and color designs
- improved bowl shape
- nice rim for spill protection
- a full-size residential style wood seat
- foot pedal flushing
- the hand spray is also included
- only one pint per flushing
- easy cleaning
- easy installation
- rim complicates cleaning of the top part
- seat not always stay locked and moves a lot
- the same problem with packing
Face To Face comparison
Design and Dimensions
As we’ve already mentioned, customers can choose between two size options, depending on the free space available. In this review, we discuss standard height toilets that measure:
- 27″ x 20.5″ x 25″
- 37.5 pounds
Low profile models offer the same functionality but smaller height:
- 22″ x 14.63″ x 15.5″
- 36 pounds
Anyway, even standard dimensions require quite a little space. Dometic 320 may cause some issues if you have a small trailer, but it mostly concerns the installation convenience.
Both models are made of ceramic, which is a considerable advantage compared to common plastic RV toilets. The ceramic design provides the same durability and comfort as home toilets.
Two color options are available – white and bone.
According to the official user’s manual, both toilets have similar ceramic bowls. They are very durable, unlike the polypropylene bases.
The main difference is the shape. On the one hand, a longer bowl feels more convenient in use. On the other hand, users note that it requires greater flushing power than it has for proper and quick cleaning.
We like a topping rim of the second appliance. Though cleaning may take more time, the rim protects you from spills supporting hygiene and cleanliness.
The flushing system of both models coincide and offers technology standard for all gravity toilets.
Toilets have a set of 360-degree jets located around the top or under the rim. Such location allows for providing powerful swirl action that flushes the contents and covers every inch of the bowl.
One of the best advantages of the Dometic RV gravity flush toilets is their water economy. You won’t need more than one pint / 0.13gal / 500 ml.
Moreover, users can control the amount of water used and spend as much water as needed right now. It’s possible thanks to the pedal system.
You press the flush pedal part way down to add water to the toilet. Water flows into the bowl while the flush ball remains closed. When you fill the bowl as much as you wanted, just press the pedal down until it contacts the floor. Flushing will happen. Release pedal after a complete flush.
Hand spray contributes to the water economy and provides additional hygienic processing. The unit comes out of the base in the back. You can use it to deal with spot messes. Just direct it and press the trigger for easy cleaning.
Hand sprays are made of plastic materials. We can’t say they’re very durable, which is their only drawback, by the way.
Please pay attention that a hand spray is an optional element that comes only in definite models. So if you need some, make sure you chose the right product. Both of our competitors provide these units.
Dometic 310 and Dometic 320 come with a full kit of elements necessary for installation. The process is quite easy even for beginners. Toilets are attached to the floor and wall with special bolts and are equipped with a nice floor flange seal.
For more information on the kit and installation, please follow the instruction. In case of difficulties, contact the User’s Service.back to menu ↑
