Now let’s take a closer look at how the two Dometic toilets differ.

Differences Between Dometic 310 and 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

This Dometic RV toilet 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 310 review

Dometic 320

There isn’t a great difference in the size though this model is elongated which gives it an extra 3 inches.

This Dometic toilet measures 22 x 14.8 x 19.8 inches.

It is, however, significantly heavier at 37 pounds.

You’ll find the flush pedal in the same position on both models.

It is elongated and also has a rim around the edge to prevent spills.

The Flush

Dometic 320 Review

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

This Dometic RV toilet also has 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 RV 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 flush also starts up near the rim in order to do the best job of cleansing the bowl and to remove all debris.

The Winner Is- The Dometic 320

Value for Money

Dometic 310 Comparison

Looking for a RV toilet, 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 $100 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

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

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 RV toilet!

We felt that these features really made this model stand out:

  • The size and height are just right, and the elongated shape overall makes it more comfortable.
  • The wooden seat is much better than the plastic.
  • The pedal flush option to just add water or do a full flush is a great way to save water.

We are not saying that the Dometic 310 toilet would be a bad choice for everyone.

Here are the main reasons why this model may be the better choice for some types of RVs and owners on a budget:

  • The non-elongated more compact design is the better choice for “RVers” with limited space availability.
  • The 360º vortex extra power flush design, though requiring more water provides an effective removing of all debris.
  • Last but not least, the cheaper price may seal the deal for the budget conscious camper.


Happy camping!
