Dometic 310 vs 320: Which RV Toilet Should You Choose?

As a seasoned RV enthusiast, I have had my fair share of experiences with various types of toilets. One of the most common toilet brands used in RVs is Dometic, and in this article, I will be sharing my personal experience with the Dometic 310 and 320 models.

First off, let me start by saying that both models are excellent options for RV toilets. However, there are some key differences between the two that may make one a better fit for your needs than the other.

Now, let’s dive in and take a closer look.

1. Design and Appearance

The first thing that caught my attention when comparing the Dometic 310 and 320 was their design and appearance. The 310 has a classic and sleek look, while the 320 has a more modern and stylish appearance. The 320 also has a taller height, which can be more comfortable for taller individuals.

2. Installation

When it comes to installation, both models are relatively easy to install. However, the 310 has a simpler installation process since it uses a traditional flange bolt mount. On the other hand, the Dometic 320 requires a bit more effort and time to install since it uses a hidden fastening system. While the hidden fastening system looks more aesthetically pleasing, it can be a bit more challenging to install.

3. Water Consumption

Water consumption is a significant factor to consider when choosing an RV toilet. The Dometic 310 uses less water than the 320, making it a more water-efficient option. The 310 only uses 0.10 gallons of water per flush, while the 320 uses 0.18 gallons of water per flush. While the difference may not seem significant, it can add up over time, especially if you are dry camping or have limited water resources.

4. Flush Mechanism

The flush mechanism is another crucial factor to consider when choosing an RV toilet. The Dometic 310 uses a standard foot pedal flush, while the 320 uses a push-button flush. The foot pedal flush is easy to operate, and you can control the amount of water used with each flush. On the other hand, the push-button flush requires less effort and is more hygienic since you don’t have to use your foot. However, you cannot control the amount of water used with each flush.

5. Maintenance and Cleaning

Keeping your RV toilet clean and well-maintained is crucial for both hygiene and longevity. The Dometic 310 has a straightforward and accessible design, making it easy to clean and maintain. The 320, on the other hand, has a more complex design, making it more challenging to clean and maintain. However, the 320 has a ceramic bowl, which is more durable and easier to clean than the plastic bowl of the 310.

The Verdict

In my opinion, both the Dometic 310 and 320 are excellent options for RV toilets, and the choice ultimately comes down to personal preference and needs. If you value water efficiency and easy installation, the 310 may be the better choice for you. On the other hand, if you prioritize style and a more hygienic flush mechanism, the 320 may be the better fit.

Ultimately, the decision comes down to your own needs and priorities as an RV owner. I hope this comparison has been helpful in informing your decision and making your RV experience more enjoyable. Happy travels!
