Now let’s take a closer look at how the two Dometic toilets differ.
Differences Between Dometic 310 and Dometic 320
Appearance
We are focusing on the standard sized, white toilets as we felt they look more modern and they are more convenient.
Dometic 310
The design has the flush pedal on the right-hand side (as you are facing it). It is 19 x 15 x 20 inches and weighs 23.5 pounds.
Dometic 320
There isn’t a great difference in the size considering this isn’t elongated. It measures 22 x 14.8 x 19.8 inches. It is, however, significantly heavier at 37 pounds. The flush pedal is in the same position. It is elongated and also has a rim around the edge to prevent spills.
The Winner Is- The Dometic 310
The Flush
Both of these Dometic toilets have a swirling jet cleaning system for a complete clean of the bowl with each flush. That being said, the flushes are different.
Dometic 310
This is a gravity flush. On top of that, it has a 360º vortex flush pattern, so the flush is more powerful.
Dometic 320
You will also have a gravity flush, but there is no 360º vortex flush pattern. It does have low flush technology, so it only requires 1 pint (5 liters) of water per flush.
The Winner Is- A Tie
The Flush Pedal
As we mentioned, both of the pedals are placed on the right-hand side when facing the toilet, but they do work differently.
Dometic 310
You will have to push the pedal all the way to the ground in order to flush.
Dometic 320
If you only press the flush half-way down, you will add water. If you push the pedal all the way down, you will get a full flush. We like this feature as it saves water.
The Winner Is- The Dometic 320
Value for Money
Looking at toilets for RVs, you will be able to find a price range from $100 to almost $300. It will very much depend on the materials.
Dometic 310
It is cheaper than the 320, and cheaper compared with other Dometic toilets, but it is still at the higher end of the price range. It comes with a two-year warranty.
Dometic 320
It is just around $10 more expensive than the Dometic 310. It also comes with a two-year warranty.
The Winner Is- The Dometic 310
Pros and Cons
Before we give our final verdict, we will list some pros and cons of these Dometic toilets.
Dometic 310
Pros:
- Incredibly easy to install
- The design allows for better water flow to the bowl
- It is a great height, even for tall people
Cons:
- People have had issues with the ball valve
Dometic 320
Pros:
- The elongated shape is much more comfortable
- The wooden seat is of better quality than the plastic
- It sits close to the wall and takes up less floor space in front
Cons:
- You need an 11-inch clearance from the flange so it may not fit in al RVs
The Final Verdict
Today’s winner was going to be the Dometic 320. We felt that the extra $20 was well worth the design alone. The size and height are just right, and we felt that it was overall, more comfortable. The wooden seat is also superior. We were convinced that having the option to just add water and full flush would be an ideal way to save water.
The size and height of the Dometic 310 are also just right. While the shape isn’t elongated, it is still extremely comfortable considering you are in an RV. Finally, we decided that the Dometic310 was the better choice, not for the design, or the value for money, simply for the flush. Probably the most important thing about a toilet is the ability to flush well each time, to keep your toilet clean and looking new. With the 360º vortex flush design, the extra power made a big difference.
