SmartBidet 2400er 01

REVIEW – I bought my first bidet at least 10 years ago, a cold-water-only model that went from zero pressure to jet-powered-fire-hose if you clicked it to the “2” setting instead of “1” while using it. Even with the drawbacks of such a model, I was instantly sold. I’ll try to keep this review PG-13 or better, but the plain truth is that every time I travel now and the place we’re staying at doesn’t have a bidet, I feel unclean until I can retreat back home. The SmartBidet SB-2400ER Bidet Toilet Seat is a feature-packed bidet worthy of any throne, at least on paper, and if it’s elongated and/or a French Curve toilet. Our particular model is elongated, and the previous bidet I had on it was getting older and wasn’t made for elongated toilets, making for a mismatch that the SmartBidet model should solve as well.

What is it?

The SmartBidet SB-2400ER Bidet Toilet Seat is a toilet seat with a built-in bidet. The electronics add a drying feature, hot water (without having to connect to a hot water pipe), a toilet seat warmer, night lighting, and a host of adjustments and controls via a wall-mountable remote control.

What’s in the box?

Design and features

SmartBidet 2400er 02

The SmartBidet SB-2400ER Bidet Toilet Seat is a wedge-shaped seat, the taller portion at the back hides the hot water reservoir and other parts. This particular model is made to fit French Curve and elongated toilets.

At the top of the seat are some physical button controls and the logo. These would work in a pinch if the remote’s batteries die, but you’ll be using the wall-mounted remote for most controls.

The remote (pictured above) has controls for adjusting the nozzle position (forward and back), various cycles including “posterior” and “feminine”, a dryer, and adjustments for water/dryer pressure, seat temperature, and water temperature, as well as an auto clean button. A small LED indicates if batteries are low (my last similar model had a remote as well, and batteries lasted over 3 years, so you shouldn’t have to worry about this too often).

Pictured above is the nozzle itself in the retracted position. To the right of the nozzle is a flap that covers the dryer vent. By retracting the nozzle and having protection over the dryer, the bidet should survive even the most horrific toilet experiences.

The lid has quite a few warning and instruction items, and the seat and lid have rubber bumpers and close softly.

Finally, a removable sticker notifies you of the hidden skin sensor. This prevents your toddlers or pets from accidentally firing off the bidet if no one is actually on the throne,

Setup

SmartBidet 2400er 14

To install the SmartBidet SB-2400ER Bidet Toilet Seat, you’ll first need to remove your old toilet seat. Then you’ll place the bracket as shown above, and insert the two large bolts (with square heads). You can see above how it offers about 2 inches of forward and backward placement adjustment.

Next, the thumb washers are screwed onto the bolts from below (I recommend not tightening them too tight yet, you’ll want to install the bidet itself later onto the bracket and then adjust it forward/backward before tightening).

You also need to install the 1/2″ compression T-valve, which adds a diversion of water from your toilet tank supply line to the bidet.

The bidet water supply hose screws onto this new connection.

And then onto the bidet itself. The bidet is installed onto the bracket by simply sliding it on (and it can be easily removed for cleaning later with the press of a button).

You’ll also want to plan where to mount the remote control, right above the toilet paper holder was an obvious choice in this bathroom.

Once the plate is installed, you simply slide the remote on, and you’re done!

Performance

SmartBidet 2400er 07

Unless you get a leaky water supply hose, like the one included in my box with the SmartBidet SB-2400ER Bidet Toilet Seat. It was leaking from the spot in the middle of the picture above, but luckily it was the same size as the water supply hose from my old bidet (and if it hadn’t been I’m sure you could have found a replacement at a home supply store of your choice. Hopefully, SmartBidet’s quality control catches these in the future (SmartBidet immediately followed up to say that they would happily replace a defective hose if needed).

The GIF above shows the bidet in action just in case you’ve never used or seen one. When you turn it on, there’s a slight delay as the nozzle pokes out from its hidey-hole, then a nice gentle cool/warm/hot stream of water gives you a cleaning vastly superior to toilet paper.

The adjustments were plentiful: the positioning and pressure/temperature settings all did what you’d want them to do, and it seems like they’d accommodate a wide variety of people sizes. My only disappointment in the weeks of review was the weak dryer, even at high settings it seems like it takes a while to dry much at all, so I reverted to simply using a bit of toilet paper (literally a 10th of what I’d probably use for regular toilet visits, just a bit to dry off). The seat warmer is also great, if you’re into that sort of thing.

What I like

  • Wide range of adjustments for pressure/position/temperature
  • Quality materials (except for the water supply hose)
  • Night light is great for middle-of-night visits

What I’d change

  • Leaky water supply hose
  • Dryer seems weak – either make it stronger or just remove it and drop price accordingly

Final thoughts

The SmartBidet SB-2400ER Bidet Toilet Seat is now a permanent addition to my bathroom, and does everything I want it to and more. I’ll update here if I run into any more issues, but it feels solid and well-built and I look forward to a lasting relationship with my SmartBidet Toilet Seat.

    1. Yep, sorry that wasn’t clear in the review – requires a standard 120V wall outlet, plug is hardwired to the bidet.

  2. Thanks for your review. I got one…however, the remote works as expected but can barely see the LEF lights when switching settings? is that normal? Even in the dark, it’s barely red or noticeable. Very very faint.

    1. I THINK that the light shows brighter when the battery is about to die, I’ve had the batteries die on me twice now (using rechargeables so they tend to die quicker than disposables), and I’ve noticed the LED much more right before they die.
