Ultra-NOVA vs Eco-NOVA: Bidet Seat Comparison

Ultra-NOVA vs Eco-NOVA: Bidet Seat Comparison

The world of bidets is evolving. NOVA bidets started to make a name for themselves with the release of the popular Eco-Nova bidet seat in 2020. 

Now with the new Ultra-NOVA bidet seat released late last year, NOVA is giving some of the bigger names in the bidet world a run for their money. 

We know that with so many options and conflicting reviews online, choosing the right bidet can sometimes feel like navigating a porcelain labyrinth. 

But don't worry- we’ll compare the Eco-NOVA vs Ultra-NOVA bidet seat and break down the key differences between the two. By the time we're done, you should know exactly which one is right for you. 

Introducing the All New Ultra-NOVA Bidet Seat

So first things first, the Ultra-NOVA is not replacing the Eco-NOVA. 

The Ultra-NOVA bidet is an upgraded version of the Eco-NOVA, with a sleeker look, more wash options, and new luxury features for a “treat yourself” moment.

At just 3.66 inches in the back, the Ultra-NOVA is the slimmest bidet seat available on the market today. We find this especially impressive considering that it's packed with so much innovative technology.

Eco Nova vs Ultra-NOVA - The Differences

Here’s quick look at what sets the Ultra-NOVA bidet seat apart from the Eco-NOVA:  

  • Automatic open/close lid
  • Enema wash
  • Slimmest seat on the market
  • Auto-flush capable
  • Side knob controls
  • User Presets
  • Risk Free Trial
  • Price

Let’s dive a little deeper into each feature and see if these features move the needle for you.

Automatic open/close lid

One of the Ultra-Nova’s standout features compared to the Eco-Nova is an auto open/close lid.

Expect more convenience, better hygiene and a little bit of wow factor that your guests will love. You can finally say goodbye to manual lid lifting and hello to a hands-free experience. 

This is a nice-to-have feature for all users, but the hands-free functionality is truly game-changing for anyone with limited mobility or injuries.

Something to keep in mind is that this function must be disabled if you want to be able to sit on the lid. Surprisingly, for such a slim and advanced bidet seat, the lid can still support up to 400 lbs! 

Enema wash

For those seeking enhanced cleansing and better bowel health, the Ultra-Nova has an enema wash feature which the Eco-NOVA lacks. 

The targeted spray stream helps get things moving without the need for a traditional enema. That means less hassle and mess for you while keeping your bowel health optimized.

In general, bidet enemas are safe and effective (as long as you don’t use them every day). We’ve heard from many people that use this function that the enema wash may take a few tries to master, but is a huge help for occasional relief. 

Ultra-Slim Seat

As we mentioned earlier, the Ultra-NOVA is the slimmest bidet seat currently available.

The sleek and modern look is one of the Ultra-NOVA’s biggest wow factors and has redefined sleek in the bidet realm. Its rear height sets it apart from other seats on the market, which can slope up to 6” in the back. 

The Ultra-Nova is slimmer than the Eco-Nova (which has a 5.2 inch rise at its highest point) by over an inch.

While the Eco-Nova certainly doesn’t look like a bulky, dated seat—we still consider it to be one of the sleekest seats available—the Ultra-Nova definitely has a slimmer profile that will look and feel amazing in any bathroom.

Optional Auto-Flush With Ultra-NOVA+

NOVA Bidet has created a new patented auto-flush feature that makes getting rid of waste more hygienic than ever. Smart sensors on the seat detect when you've finished up and trigger an automatic flush, much like one found on the TOTO Washlet S7A

Like the auto open/close feature, this is a great feature for anyone—but is especially helpful if you have an injury or physical limitations like arthritis that makes manual flushing difficult.

Auto-flush is available only on the Ultra Nova+ model. Besides a slight increase in price, the auto-flush feature is the only difference between the Ultra-NOVA and the Ultra-NOVA+. 

Also important to note: The auto-flush feature found on the Ultra-NOVA+ is only compatible with top flush or dual flush toilets like the TOTO Aquia IV.

Side Knob Controls

Another cool thing we're loving about the Ultra-NOVA is the ability to use it even when the remote is out of reach. 

We've all been there before - you sit down in a hurry and don't realize the remote is on the floor somewhere or behind you where you can't access it.

Or what if the remote runs out of battery or just isn't working for some reason?

Now you also have the option of controlling everything from an easy to use side knob control. 

User Presets

Another thing the Ultra-NOVA's got going on over the Eco-NOVA is the ability to store up to two individual user's settings. 

Now you can save your preferred water temperature, pressure and heated seat temperature to your liking.

One less thing to argue about if someone else using the seat likes the features set a different way!  

Risk Free Trials: 30 vs 60 Day

Another area where there is some overlap is in the risk free trials department.

Though both of these bidet toilet seats offer a risk free trial, the Ultra-NOVA’s is 60 days while the Eco-NOVA’s is 30 days. 

Virtually all other bidet seats are non-returnable once they have been used or installed, but these two seats, along with the Cascade 3000, can all be used and returned within 30 and 60 days depending on the seat.

Not too surprisingly, there is a large difference in price between the Eco-NOVA and the Ultra-NOVA. 

For the amount of features and the overall design of the Ultra-NOVA, we feel like the price is more than justified as a high end luxury seat. 

If you’re looking for a bidet seat in  a more affordable price range, then the Eco-NOVA would be our number one choice.

Eco Nova: A Legacy of Comfort and Convenience

While the Ultra-NOVA bidet takes the spotlight with its cutting-edge features and super sleek look, the Eco-NOVA remains a solid choice for those seeking a reliable and comfortable bidet seat experience.

Read any Eco Nova bidet seat reviews and you’ll see why users love it so much. In fact, if you search online for the Eco-Nova bidet, Reddit users swear that it has the feel and experience of a high-end seat without the matching sticker price.

The Eco-NOVA has many of the same luxury features as the Ultra-Nova, including:

  • Instant warm water: No more uncomfortable cold surprises, thanks to the built-in instant heater.
  • Sittable Lid: Both seats have a sittable lid of up to 400lbs
  • Silver nano sterilization: Sterilizes the wash water and bidet wand before use
  • Powerful spray functions: Enjoy adjustable pressure, pulsating massage, and oscillating nozzle movements.
  • Heated seat: Especially inviting during colder months.
  • Warm Air dryer: Go green and ditch the toilet paper completely.
  • WarrantyPremier BIdets offers an exclusive full three extended warranty on both the Ultra-NOVA and Eco-NOVA bidet seats

As is the case with the Ultra-Nova, the Eco-Nova does not come in a round toilet seat size (elongated only). 

Which is the Best Bidet Toilet Seat to Buy?

Both bidet seats are great for different reasons, so it really depends on some personal preference.  

Here are a few things to consider:

For tech enthusiasts and hygiene aficionadosthe Ultra-NOVA's cutting-edge features might be worth the splurge.

  • Auto-flush
  • Auto open/close lid
  • Enema wash

For value-minded users and comfort loversthe Eco-NOVA offers a near-luxury bidet experience at a more budget-friendly price.

For anyone with physical limitations, the Ultra-Nova has extras like an auto open/close lid and auto-flush that will make your bathroom experience a little easier.
