Look & Feel

Color & Profile

The Eco NOVA and Bio Bidet BB-1700 each come in crisp white, so they’re easy to match with a variety of bathroom color schemes. Each has a streamlined, modern look, though the Eco NOVA is much thinner than the BB-1700. In fact, the Eco NOVA is one of the slimmest seats on the market thanks to an ultra-efficient design that packs the internal components snugly into the shell.

Both the Eco NOVA and the BB-1700 are designed for elongated toilets only. If you’re looking for a bidet with a round seat option, we’d recommend the Cascade 3000 in place of the Eco NOVA or the Bio Bidet BB-2000 in place of the BB-1700.

Materials

Bidet seat shells are typically constructed from plastic, while the wand and nozzles can be made out of plastic, aluminum, stainless steel or a combination of materials. Bidet manufacturers use either ABS plastic or polypropylene plastic for the shell. Polypropylene plastic is stronger and more durable than ABS plastic, but it’s also more expensive, so ABS plastic is used most often.

Many manufacturers do not specify the type of plastic they use in their bidet seats, but that’s not the case across the board. The Eco NOVA, for example, is made out of polypropylene plastic, so it’s strong and built to last. The Eco NOVA’s nozzles are also high quality, crafted from stainless steel for superior durability and cleanliness.

At this time, we haven’t been able to confirm the type of plastic used to make the Bio Bidet BB-1700, but the wand is crafted from stainless steel and has plastic nozzle tips. As an added bonus, the BB-1700’s nozzles can be popped off and replaced in the comfort of your own home should the need arise. Most other bidet seats must be sent to a repair facility if the nozzles have an issue.

Wash & Dry Features

Wash Settings

The Eco NOVA has a raft of wash options and a good range of water pressures, making it easy to get one hundred percent clean. In addition to standard front and rear wash modes, the Eco NOVA also offers a stronger turbo mode. Optional nozzle oscillation moves the wand forwards and backwards to soothe your underside, stimulate the bowels, and increase cleansing coverage. The Eco NOVA also offers an invigorating pulse wash that alternates the water temperature between warm and cool for a sitz-bath effect.

The Bio Bidet BB-1700 also offers front and rear wash modes, pulse wash, nozzle oscillation and an “enema wash” option. Referred to as “turbo washing” by Bio Bidet, the enema function directs a powerful, thin stream of water into the rectum to break up constipation and stimulate the bowels. Keep in mind that the BB-1700’s turbo wash is truly designed to act like an enema, whereas the Eco NOVA’s turbo wash is simply a strong cleanse. The BB-1700 also features strong water pressure, which many people like, but it’s less adjustable than the Eco NOVA’s and may feel too strong for some users.

Night Light & Deodorizer

The Eco NOVA has a helpful, built-in night light that automatically switches on once the bathroom light drops below a certain threshold. The gentle, blue glow illuminates the bowl, making it easier to navigate the bathroom or aim for the toilet.

The Bio Bidet BB-1700 doesn’t have a night light but it does come with its own special perk: a deodorizer! The deodorizer purifies the air from the bowl by drawing it through a special filter, removing odors in the process. It’s an all-natural, scent free way to keep your bathroom smelling fresh no matter what’s happening in the toilet bowl! The Eco NOVA does not have a deodorizer.

Nozzle Sterilization

Both the Eco NOVA and the Bio Bidet BB-1700 rinse their nozzles with fresh water after use, but the Eco NOVA takes cleanliness a step further with two nozzle sterilization systems. The Eco NOVA’s first line of defense against germs is a silver nano coating on the inside of the tubing and nozzles. Silver’s antibacterial properties act as a natural deterrent against microbial growth, keeping the water clean as it travels from your pipes to your rear. The Eco NOVA’s second sterilizing element uses ultraviolet light to kill any germs lurking on the surface of the nozzles themselves.

The Bio Bidet BB-1700 does not have nozzle sterilization.

Auto Wash

Both the Eco NOVA and the Bio Bidet BB-1700 have auto washing, a feature that initiates a full wash and dry cycle at the touch of a button. The big difference between the two is timing. The Eco NOVA’s auto wash function provides a 90 second wash followed by a 4 minute dry, while the Bio Bidet BB-1700’s auto wash offers a 30 second wash followed by a 1 minute dry.

So does wash and dry time really matter? As a matter of fact, yes. In general, it takes at least 30 seconds of wash time to get clean after a bowel movement, sometimes more depending on the situation. And it takes most bidet air dryers 3-5 minutes to get wet skin completely dry. This means that a longer auto wash cycle is more likely to get you completely clean and dry than a shorter one, even if it does take up a bit more of your time overall.

Comfort & Convenience Features

Controls

One of the most obvious differences between the Eco NOVA and the Bio Bidet BB-1700 are the controls. The Eco NOVA comes with a sleek and stylish rose gold remote. Crafted from brushed stainless steel, the remote has a satisfying weight and hand feel, and the raised buttons are labeled with words instead of images. The remote also comes with a mounting dock that can be affixed to the wall so that it is always within easy reach. One special benefit to the Eco NOVA’s remote is that it uses a radio signal rather than an infrared signal to communicate with the seat. Radio signals are much harder to interrupt compared to infrared, which means the Eco NOVA’s remote functions very reliably.

The Bio Bidet BB-1700’s control are located on a panel attached to the side of the seat, ensuring that it never gets lost or misplaced, and the buttons are labeled with both words and pictures. Unlike a remote, side arm controls run on the seat’s electrical wiring, so you never have to replace batteries. However, the placement does pose a challenge for individuals who have difficulty looking down or limited vision, do not have the use of their right hand or arm, or have a large physique.

Lid

Most bidet lids are only meant as a covering for the toilet bowl and can’t support any extra weight. The Eco NOVA, however, is an exception! The Eco NOVA’s heavy duty lid has the same 400-pound weight capacity as the seat itself, making it ideal if you like to sit on your toilet lid as you trim toenails, dress, or help someone bathe. The BB-1700’s lid cannot support extra weight; sit on this lid, and you may end up breaking it or damaging the seat’s internals!

Warranty

If you’re looking for a resource that covers the ins and outs of bidet warranties, we’ve got you covered in this post dedicated specifically to the topic. But in a nutshell, the Eco NOVA and Bio-Bidet BB-1700 both come with full warranties. This means that all eligible repairs will be covered at 100% for the duration of the warranty. The Eco NOVA comes with a 4-year warranty that can be upgraded to 5 years for $79 or 6 years for $99. The Bio Bidet BB-1700, on the other hand, has a 3-year full warranty that can be upgraded to 6 years of full coverage for $99.
