If you are looking to add luxury and comfort to your bathroom routine at an affordable price, the Kohler Novita BG-90/93 and Bio Bidet A7 are two wonderful bidet seat models to consider. Below, we sort through the specific details and differences between these two seats so you can choose the best option for you and your household.
The Kohler Novita BG-90/93 and Bio Bidet A7 bidet seats are both crafted with quality materials to add comfort and convenience to your bathroom routine. These seats are designed with a sleek, smooth and modern look and come equipped with convenient side controls attached to the right side of each unit. Additionally, both of these seats come in a classic white color and the BG 90/93 features silver accents as an added style element. It’s also worth mentioning that the A7’s side control has cool LED light illumination to help with visibility and choosing options.
For added versatility, the BG-90/93 is available in a round and elongated seat option, while the A7 comes in only the elongated style.
If you or someone in your household makes frequent night time visits to the bathroom, a great option to have on your bidet seat is a built-in night light. The Bio Bidet A7 includes a convenient, integrated LED illumination feature that produces a soft glow so you can easily find your way around the bathroom in the dark of night without turning on blinding, overhead lights.
The Bio Bidet A7 comes equipped with a tank style water heater that will produce 40-60 seconds of warm water before needing to refill and reheat. It then takes around 3 to 5 minutes for the tank to refill. In contrast, the Kohler Novita BG-90/93 comes with a hybrid style heater that works by filling and heating the water tank to supply the wash cycle on demand. The hybrid style heater is an improvement on the basic tank system as it can provide up to 90 seconds of warm water at a time. If you have a smaller household, the water heater design may not be an issue, but if you have multiple people in your home who will be sharing one bidet seat, a hybrid style water heater might be a little more accommodating. Additionally, a hybrid water heater is more ideal if you simply need to activate a longer wash cycle.
The Kohler Novita BG-90/93 comes equipped with dual nozzles: one nozzle is dedicated to the feminine wash and the other is dedicated to the posterior wash. In contrast, the Bio Bidet A7 includes just a single nozzle with a 2-in-1 function, meaning the front and rear washes are both performed by just one nozzle. Although they are stylistically different, the nozzles on both of these seat models are adjustable, self cleaning, oscillating and made of hygienic stainless steel. Fortunately, stainless steel is a great, sanitary material for bidet seat nozzles since it naturally resists bacteria and germ build-up. Worth noting, the BG-90/93 also offers additional nozzle sterilization with a silver-nano solution.
Although it is rare that you will ever need to replace your bidet seat nozzles, the Kohler Novita BG-90/93 nozzles are easy to remove if necessary, while the Bio Bidet A7 nozzle does not come off easily and requires professional servicing to replace.
Wide Spray is a nice wash option offered by the Bio Bidet A7 that provides more water spray coverage. Additional coverage results in a more effective wash that will get you clean and on your way a little quicker.
The warm air dryer is a great feature offered by the Kohler Novita BG-90/93 that allows you to reduce the amount of expensive and scratchy toilet paper you use. Not only will you be adopting a more eco-friendly bathroom habit by using less paper, you will also save money. Unfortunately, the Bio Bidet A7 does not have a warm air dryer.
Another great feature that comes included with the Kohler Novita BG-90/93 is the powerful deodorizer. Through this feature, a fan pulls air through an active carbon filter, which effectively neutralizes smelly odors. With this feature, you no longer have to feel embarrassed or worried about how your bathroom smells since the deodorizer will leave the air fresh and clean.
Those looking for the convenience and ease of an automatic wash and dry at the touch of a button will love the one button wash & dry offered by the Kohler Novita BG-90/93. This feature allows you to skip over the programming and multiple options for a simple wash and dry cycle. The one button wash & dry is also known to be a must have feature for those of a elderly age who will be using the seat and may be intimidated by numerous programming options. The Bio Bidet A7 does offer a great one button automatic wash function, but unfortunately there is no drying feature.
This is an excellent option to have if you will be sharing your bidet seat with another household member. Through user presets, you have the ability to pre-program your favorite settings into the control panel so the bidet seat can perform your personal wash options at the touch of single a button. The Bio Bidet A7 comes equipped with this convenient feature and allows for you to set presets for up to two users.
The Kohler Novita BG-90/93 comes with an added child safety feature that can be programmed via the controls for those with young children who may be interested in using a bidet. When the child mode function is in use, the water pressure, temperature and dryer are automatically lowered to better accommodate a young person. The Bio Bidet A7 does not offer any sort of child mode and it is recommended that children not use the unit.
Both Bio Bidet and Kohler offer full one year warranties. However, Bio Bidet excels in the area of extended coverage. Though Kohler offers the option to upgrade to a generous 3 year full warranty, Bio Bidet doubles that and offers an impressive 6 year full warranty. If you’d like the peace of mind that comes with having additional insurance on your investments, Bio Bidet is a great company to work with.
When it comes to deciding whether to purchase the Bio Bidet A7 or the Kohler Novita BG-90/93, it’s important to consider which features would be most practical for you and your household. Both of these seat models come equipped with some great options and also come in at an affordable price point. If you want a deodorizer, warm air dryer and hybrid water heater, the Kohler Novita BG-90/93 may be the best choice for you. On the other hand, if you prefer having user presets and the LED night light, you might be inclined to go with the Bio Bidet A7. Regardless of your feature preferences, each of these seats have great wash options that will certainly upgrade your overall bathroom experience.
