Key differences between Dometic 310 and 320

Without knowing the differences, comparing is impossible. So let’s check out the key differences between Dometic 310 and 320.

Comfort

The comfort depends on the seat size. If you are a small man or woman, a small seat will deliver more comfort compared to a large seat. The opposite is true for large men and women. A small seat will feel risky and uncomfortable for a large man.

You will have a smaller seat for Dometic toilet 310. It is designed to be compatible with RVs. The seat is perfectly comfortable for a small man or woman. On the flip side, Dometic toilet 320 features a large and elongated seat to provide a residential toilet feeling. You can get superior comfort in 320 if you are a tall and large man or woman.

Construction

The seat construction also plays a vital role in comfort as well as durability. Obviously, a wooden top-quality seat will be more durable compared to a plastic seat. The 320 model offers a full-size residential-style enameled wood seat. You will get a home feeling. Also, it will deliver longevity and durability.

On the contrary, the 310 model offers plastic seat construction. It might perform well in the short run but cannot perform in the long run. The 320 model wins here and you should pick it for long-term use. However, you can upgrade the seat to 310 if you want.

Capacity

The bowl capacity is not a big deal for most people since the chance of overflowing is very low. However, some people find it more convenient to use a deep-depth bowl. The Dometic 320 comes with a deep, vitreous ceramic bowl. Go with this model if you love to use an elongated bowl.

Of course, you can go with the 310 as well. The depth of its bowl is not that small. Any average size man might not find any differences using any of these toilets. So you don’t have to worry about the bowl depth here.

Flush design and water use

The flush design is another way to differentiate between 310 and 320. Both models offer gravity-flush and foot pedals. You can add water as per need. The Dometic 310 RV toilet comes with a rimless 360 degrees vortex flush pattern design. It is very effective and extremely easy to clean. You need to put less effort into maintaining hygiene here. However, it might not prevent splashing.

On the other hand, the 320 model features a pressurized full-rim flush. You can clean the bowl with one pint of water due to the pressurized function. Also, it is effective and prevents splashing. However, keeping it clean is harder compared to 310. 

Weight and size

In the Dometic 310 vs 320 comparisons, the weight and overall size should be a matter of concern. You might not want a large toilet in your RV to possess a huge area. Or maybe you want to feel comfortable with a large one. The 310 focuses on this part and it takes less space in your RV compared to 320. They might sacrifice comfort to make it more compatible with the RVs.

Weight is another considerable factor since we are dealing with RV toilets. The 320 model weighs 37.5 pounds where the 310 model weighs only 23.5 pounds. It might not be a big deal for some people but trust me, those 14 pounds create a difference.

Similarities between Dometic 310 and 320

Along with the key differences, knowing the similarities will help you make a better decision. Here are the similarities between these two models from Dometic.

Bowl construction

The bowl is the most significant part of a toilet. It has to be durable and well-built. Good news is, both the 310 and 320 models offer 100 percent vitreous ceramic construction. You can expect a longer lifespan from both models due to the enamel coating. Also, it stays shiny, scratch-free, and long-lasting for a long time.

Foot pedal

Maintaining hygiene is important in toilets, especially when you are in an RV. A foot pedal can play a major role in ensuring hygiene. The gravity-flush and foot pedal are offering you exactly that opportunity. You can use your foot to flush the bowl. It helps to maintain hygiene all the time.

Seat height

The seat height determines the seating comfort. If it is too high or too low, you might feel uncomfortable sitting on it. Also, not all heights are suitable for all people. That is why both the 310 and 320 models offer an 18-inches standard height. You can even get a 14 inches low-profile seat in the 320-model.

Installation

Installation is simple in both models. You can install them yourself with their two-bolt installation. It takes less than an hour to install the toilets in your RVs. Their easily accessible water connection line enables even easier installation.

Hand Sprayer

The sprayer is an effective tool to compensate for any lack of flushing. Both the 310 and 320 models come with an optional hand sprayer. You can use the sprayer to rinse and clean the toilet properly.
