Look and Feel
The TOTO Neorest RH and the Bio Bidet IB-835 each embody a different design aesthetic, so deciding which look you like will largely rest on personal preference. Both units are skirted, meaning that the sides are smooth from top to bottom for easier cleaning, with the main difference being that the IB-835’s base is tapered at the bottom, giving it a more contoured look than the Neorest RH. In addition, the Neorest RH has a low profile seat with rounded edges, whereas the back of the Bio Bidet IB-835 comes up a bit higher and has a more angular silhouette. Last but not least, the Bio Bidet IB-835 comes in white only, and the Neorest RH comes in both white and beige.
It’s worth noting that the TOTO Neorest RH is a bit more water efficient than the Bio Bidet IB-835, using 0.8-0.11 gallons per minute to the IB-835’s 0.18 gallons per minute. Theoretically, greater water pressure equates to a more thorough wash, but the difference here is so slight that it’s unlikely you’d notice a difference between the two. The main takeaway is that, over time, the Neorest RH will use less water than the IB-835.
The TOTO Neorest RH comes with an instant water heater that is capable of producing unlimited warm wash water. The only downside to this is that there may sometimes be a brief burst of cool water at the very start of the wash cycle, particularly if it’s been a while since the unit was used. The Bio Bidet IB-835 has a tank water heating system that keeps a finite amount of water heated at any given time. If you were to run a long wash cycle or use the unit several times in a row, the warm water tank may deplete, at which point the bidet would switch to using room temperature water. Once the tank refilled with warm water (which usually takes a few minutes), the bidet would return to using warm wash water. If running out of warm water is a deal-breaker, you may want to consider the Neorest RH for its instant water heating capability.
Flush volume is another area where the TOTO Neorest RH comes out ahead of the Bio Bidet IB-835. Not only does the Neorest RH come with two flush options (0.8 and 1.0 GPF depending on whether you’re flushing liquids or solids), both flushes also use less water than the IB-835’s 1.6 gallon single flush option. If you’re worried about how this lower flush volume affects flush power, you can rest easier knowing that the Neorest RH’s flushes don’t really trade effectiveness for efficiency–in other words, you’ll be getting the best of both worlds with the Neorest RH’s mighty, yet water-conserving, approach to getting rid of waste.
Comfort & Convenience
The TOTO Neorest RH’s PREMIST feature coats the bowl with a thin layer of water prior to each use to cut down on the chances of waste and build-up sticking. This translates into a unit that stays cleaner longer. The Bio Bidet IB-835 doesn’t have this feature, so it will require cleaning at the same rate as your traditional toilet.
Many of TOTO’s integrated units, including the Neorest RH, use sterile, electrolyzed water (EWATER+) to PREMIST the bowl and to sanitize the bidet’s nozzles each time it’s used. The Bio Bidet IB-835 rinses its nozzles after each use but it does so with regular water, not sterile EWATER+.
The builtin nightlight on the TOTO Neorest RH illuminates the bowl with a soothing glow, making it easier and safer for you to find your way to the toilet in low light. Though the Bio Bidet IB-835 doesn’t have a built-in nightlight, you do have the option of purchasing an after-market nightlight and installing it yourself. It won’t look quite as streamlined as the built-in kind, but it will perform the same.
The TOTO Neorest RH is measurably more water efficient than the Bio Bidet IB-835, making it the greener, more cost effective model. The Neorest RH also comes with extra features that the IB-835 doesn’t have, like a dual flush, PREMIST, EWATER+, and a built-in nightlight, as well as an instant water heater that provides never ending warm wash water. However, the Neorest RH’s efficiency, wider array of features, and beige color option do come with a higher price tag–depending on the color you choose, the Neorest RH will run approximately $990 to $1450 more than the IB-835. If you can swing the higher price, it’s well worth the investment. If you’re looking to pay less, or if you’re willing to trade the Neorest RH’s extra features for the sleeker looki of the IB-835, you’ll still be getting a high-performing, quality unit.
