Detailed Comparison: Brondell Swash 300 Bidet Seat vs Bio Bidet A7 Aura Bidet Seat


The Brondell Swash 300 is priced at $249.00, and, for $100 more, the Bio Bidet A7 Aura can be purchased for $349.00. If you want to make the smallest commitment possible while still purchasing a well-made bidet seat, the Brondell’s Swash 300 makes your choice easy. However, the Bio Bidet A7 shouldn’t be overlooked. This model provides amenities that are essential to new and experienced bidet users alike, and its design maximizes high-end longevity at an entry-level expense.

Warranty Upgrades

Both models offer a one year warranty, but with the Bio Bidet A7 Aura you can upgrade to a 6 year, full warranty.  If you’re looking for additional peace of mind, this is well worth considering.


As far as sizes are concerned, the Brondell Swash 300 is at home in any bathroom whether you are fitting the bidet seat to a round or elongated toilet. Even though it only fits elongated toilets, the host of other conveniences makes the Bio Bidet A7 hard to pass up.


Bio Bidet’s A7 Aura is controlled through its side panel, that remains fixed to the model itself. While the bidet seat is still easy to use, a stationary control panel is a bit of a drawback. With a wireless remote, Brondell’s Swash 300 provides tetherless control that comes to you. The remote also comes with a sensible holder that can be attached, via screws or adhesive, to virtually any surface, allowing you to mount the remote wherever you see fit.

Auto Wash

The title of this amenity says it all. With the push of one button, whoever is using the Bio Bidet A7 can get a complete cleanse. This is very handy for you or your guests who may not have previous experience with bidets, and would like a really quick tutorial without needing to reference the owners’ manual or study the options.

Nozzle Configuration

The dual nozzles found on the Brondell Swash 300 can be an additional source of minor comfort for new bidet owners and users because one nozzle is used for posterior cleansing and the other is dedicated to anterior cleansing. However, this one detail shouldn’t be the deciding factor between these models. The Bio Bidet A7 Aura’s single nozzle configuration is designed to offer an equally successful wash. By default, this layout allows for a perfectly centered alignment. Coupled with the oscillation and wide spray features, the same nozzle provides adjustable and thorough cleansing in both front, rear, and side-to-side areas.

Nozzle Position

Everybody is a little different with different preferences and needs especially when it comes to using a bidet. The Bio Bidet A7 Aura is able to accommodate the needs of most users with 5 levels of adjustment for both front and rear cleanses. Even though Brondell’s Swash 300 does offer dual, posterior nozzles, they are fixed in place.

Nozzle Material

The nozzles of the Brondell Swash 300 are made of plastic which helps to keep the overall cost of the model down. The Bio Bidet A7 Aura’s nozzles are made from stainless steel which gives it a higher-end longevity without the high-end price tag.

Nozzle Oscillation

With an extra press of the cleansing or bidet buttons on the Bio Bidet A7 Aura’s control panel, the nozzle will oscillate from front to back. This provides a wider cleansing area when needed. The Brondell Swash 300’s dual nozzles do not have this function and remain fixed in place.

Wash Pulse

Another feature Bio Bidet A7 Aura offers, that the Brondell Swash 300 lacks, is a massage option, that can be run during either an anterior or posterior cleanse. In this mode, the water pressure alternates between stronger and weaker sprays which creates a soothing massage.

Spray Width Option

We’ve already mentioned the single nozzle of the Bio Bidet A7’s ability to offer a wider cleansing range front to back through the oscillation function. You can also widen the spray of water itself which increasing the potential cleansing area from side to side . Though the Brondell Swash 300 has dual nozzles, neither of the nozzles can do this.


The Bio Bidet A7 Aura has a soft, LED nightlight that makes night time trips more convenient, and the use of harsher, overhead bathroom lights unnecessary. While by itself, a nightlight can be considered a minor detail, but, added onto the many other comforts, it increases the level of luxury that much more.

Sittable Lid

The lid for the Brondell Swash 300 is designed to be used as a seat if needed with a weight limit of 270 pounds. For many bathrooms, a toilet lid does double duty as a simple seat when needed. What many do not realize is that the lids of most bidet seats, such as the Bio Bidet A7, aren’t necessarily designed for this task. You might never have a problem, but you will notice the lack of stability in a lid not designed to be used as a seat. You could also cause such a lid to crack which shortens the overall life of your bidet seat.

Weight Limit

The Brondell Swash 300 has a weight limit of 330 pounds. The Bio Bidet A7 Aura is a bit stronger with a 400 pound weight limit.


When taking into account the differences of these models, the choice comes down to what type of design is more important to you as the customer. The Brondell Swash 300 offers more versatility. No matter if your bathroom has a round or elongated toilet, the Brondell Swash 300 will work for you. By comparison, the Bio Bidet A7’s design seems to be centered around providing the most refreshing and convenient bidet experience for the price. The one button Auto Wash, the oscillation, the massage, and the nightlight are just a few of the comforts bundled into this impressive model.
