Sanyipace Smart Bidet (SU01B): A Hands-On Install and Review

My family has used bidet seats in our house for years now, and honestly, once you get used to one, going back to a plain toilet seat feels like a downgrade. So, when Sanyipace reached out about the Sanyipace Intelligent Toilet Bidet Seat (model SU01B), I was ready to swap out my old one, which had finally given up after years of service. (*Disclosure below.)

In this article:

• I installed it myself, hit a few plumbing surprises along the way, and have some real opinions after a week of daily use with my family
• The Sanyipace SU01B is a smart bidet toilet seat that replaces your existing seat and adds warm water washing, seat heating, and warm air drying
• Standout features include a touchless heated seat, three wash modes, a built-in water filter, and a soft-glow night light
• It’s a good fit for households that already like the idea of a bidet but want more comfort features, like families replacing an aging bidet seat
• Priced at $239.99 (regularly $299.99), with an extra 15% off using my code HTD15

Sanyipace sent me this unit to test, and I decided to film the whole process: unboxing, installation, and living with it afterward. I’ve installed a few bidet seats over the years, so I figured I had a decent handle on what to expect. That turned out to be mostly true, though my old house threw some wrenches into the mix (pun intended) about how this installation was going to go.

In this review, I walk through what’s in the box, how the install went (including a plumbing hiccup that sent me to a hardware store and a plumbing supply store), how the remote and features work, and what my family and I think after using it daily for about a week. I also cover pricing, who I think this bidet seat makes the most sense for, and some honest thoughts on where it falls short.

About the Video Review

My video on the Sanyipace smart bidet is part review and part how-to, so you can watch me open the box, walk through the parts, and install the SU01B on my toilet. If you’re on the fence about doing this yourself, the video is worth watching because you’ll see exactly where I ran into trouble and how I worked around it.

The video also covers a full tour of the remote control, including a few hidden functions that aren’t obvious from the manual alone. If you’re a visual learner, or you just want to see the seat’s auto-open feature and the cleaning wand in action, that’s all in there too.

What’s in the Sanyipace Smart Bidet Box (And Why It Matters for Installation)

Before getting into features, it’s worth walking through what comes in the box, because it matters once you start installing. Sanyipace comes with a printed manual with color photos, a mounting bracket and hardware, the remote control with batteries already included, an information card for claiming a replacement filter and fragrance tablet, and the toilet seat itself wrapped in protective plastic.

Two things stood out to me as I unpacked everything. First, there’s a fairly substantial water filter that attaches to the incoming water line, something I hadn’t seen included with other bidet seats I’ve owned. Second, there’s an aromatherapy tablet that slots into the unit (unexpected), plus nozzle connectors and a water supply line for hooking everything up (expected). The manual walks through the mounting bracket, the knobs, and the remote control, and it’s detailed enough that I actually read it, which isn’t something I usually do with this kind of product.

The box itself calls out the core feature set right on the packaging: auto-open and close for the seat and cover, a night light, multiple cleaning modes, warm-air drying, seat heating, and aromatherapy deodorization. It also flags something important before you even open the box: this seat is meant for oval and elongated toilet bowls, not the squared-off style. Sanyipace’s site lists the exact measurements you need to check (bowl length, bowl width, and mounting hole spacing), and I’d recommend measuring your toilet before ordering rather than assuming your bowl shape will work.

Key Features That Make the Sanyipace Smart Bidet (SU01B) Worth Considering

The core pitch of the SU01B is comfort and hygiene layered on top of a standard bidet function, and a few features stood out once I started using it daily.

The touchless heated seat is the one my family noticed immediately. You can set the seat temperature across four levels, which is great (especially during the colder months ahead). Nobody in my house enjoys sitting down on a cold seat at night, and this solves that problem outright.

The three wash modes (rear wash, feminine wash, and a pulsing wash during both of those cycles) cover the basics well. I set my water temperature to 93 degrees, which felt like a good middle ground, though you can bump it up to 99 or 104 if you want it warmer. The water pressure is adjustable too, and I’d call it solid, not the strongest I’ve used, but strong enough to get the job done without feeling harsh.

The warm air dryer is a feature I didn’t expect to like as much as I do. It’s essentially a small adjustable fan built into the unit, and once you get used to it, skipping toilet paper entirely becomes second nature. Combine that with the built-in water filter, which I hadn’t seen on any bidet seat I’ve owned before, and the aromatherapy deodorizer, and you end up with a unit that’s thought through the full experience, not just the wash cycle.

Installing the Sanyipace Smart Bidet in an Old House

My house is somewhere between 60 and 75 years old, and the plumbing shows it. I already had a bidet seat installed before this one, so I figured I had a head start, and I did, but not without a few surprises.

The seat mounting itself was straightforward. I measured the mounting hole spacing first, since Sanyipace specifies it needs to fall between 11 and 19 centimeters, and mine came in around 14, right in range. The bracket uses plastic plugs and self-tightening screws, and it took more turns than I expected to get fully snug, but once it locked in, it wasn’t going anywhere.

The plumbing was where things got interesting. My old setup used a coupler that didn’t match the fittings Sanyipace includes, a half-inch versus five-eighths-inch mismatch, so I made a run to the hardware store for a ten-dollar adapter hose. Then I hit a second issue: the installation photos and video showed the connections in a way that didn’t match what I needed for my toilet. After talking with a couple of plumbers, I figured out that one fitting screws into the tank itself (a 7/8-inch connection, which is standard for most American toilets), while the other end connects to the water supply. Once I reversed the order from what the documentation showed, everything lined up. Quick tip: I also wrapped the threads in plumber’s tape after noticing a small leak at first, which fixed it completely.

If you’re installing this yourself, my honest advice is to read through the manual fully before you start, and don’t assume the included photos will match your exact toilet setup. Mine didn’t, and the manual was a bit sparse on the details of the connections. Even the QR Code-driven video wasn’t correct for my install. It’s not a hard install, but plumbing quirks in older homes can throw a wrench into even a “10-minute” installation.

Getting to Know the Remote and Features

Once the water was back on and the unit powered up, the tank started filling and the seat opened on its own, which was my first real look at the presence-sensing feature in action.

The remote covers pretty much everything: power, seat and cover open/close, water temperature (93, 99, or 104 degrees), seat temperature on the same scale, and four levels of air-drying speed. There’s also a night-light toggle, eco mode, water-pressure adjustment during cleaning, and control over where the spray wand extends. One quirk I noticed right away: the unit’s display shows temperature in Fahrenheit, but the remote shows it in Celsius. I haven’t found a way to switch that yet, so I’ve just gotten used to doing the mental conversion.

There’s also a side knob built into the unit itself if you don’t have the remote handy, and the manual walks through how to use it. Beyond the main controls, there are a few hidden functions you only find by digging into the manual, like adjusting how far back the seat and cover swing before they’d hit the tank behind them. I had to tweak that setting after my seat cover kept slamming into the tank on the first try. There’s also a sensor distance adjustment for the auto-open feature, though I’ll admit it isn’t very intuitive, and the manual doesn’t explain it well.

The seat and cover both have an assisted close, so a light push sends them down gently instead of slamming, and a light lift opens them the same way. The cleaning wand extends and retracts with a dedicated remote button, and watching it work the first time was oddly satisfying.

Living With the Sanyipace Intelligent Bidet: A Week of Everyday Use

After about a week of daily use with my family, a few things have become clear. The automatic seat-opening feature, which opens the lid when it senses someone approaching, is a neat idea, but it startled one of my daughters so much that we turned it off entirely. The good news is you can still open and close everything manually with or without the remote, so we didn’t lose any functionality, just automated one less step.

The water pressure has held up consistently for daily use. It’s not quite as strong as another bidet I’ve used in the past, but it gets the job done well, and the adjustable pressure setting lets everyone in the family dial it to their preference. The seat heating and water temperature controls have gotten real use too, especially since cooler nights make a heated seat feel like a small luxury rather than a gimmick.

I haven’t had a single leak since fixing that initial plumbing connection, which is the outcome I was hoping for after all that troubleshooting (again, I highly recommend using plumber’s tape on all connections; it’s too bad that Sanyipace doesn’t include a small roll with the installation hardware). The aromatherapy deodorizer has held up well so far, and I now use the warm-air dryer every single time. It’s become one of those features you don’t think about until you don’t have it.

Who Should Consider the Sanyipace Smart Bidet

If you’re thinking about upgrading to a bidet seat or replacing one that’s finally given out, the SU01B makes the most sense.

• Families replacing an aging bidet seat: If your current unit is on its last legs, like mine was, the SU01B is a solid, feature-complete upgrade with built-in heated seating and drying.
• Households wanting to reduce toilet paper consumption: Due to our older pipes, we try to minimize or eliminate the use of toilet paper in our wastewater. Bidets offer the best solution for this.
• Anyone who wants a built-in water filter: If you’ve never had a bidet seat with in-line filtration, this is a nice step up that I hadn’t seen on previous units I’ve owned.
• People sensitive to cold bathroom trips: Between the heated seat and warm water, this seat solves the “why is everything cold at 3 am” problem pretty completely.

Technical Details and Specifications

Here’s where the actual numbers matter, especially if you’re checking whether this will fit your toilet before you order.

Spec	Detail
Model	SU01B
Seat Shape	Elongated / oval-front (not compatible with square bowls)
Dimensions (L x W x H)	19.7″ x 14.5″ x 4.72″ (500 x 370 x 120 mm)
Bowl Length Needed	At least 20.1″ (51 cm)
Bowl Width Needed	Approximately 14.6″ (37 cm), +/- 0.8″
Mounting Hole Spacing	4.3″ to 7.5″ (11 to 19 cm)
Power Supply	AC 120V +/-10%, 60Hz

Those bowl measurements matter more than any other spec on this list. I measured my mounting hole spacing before installing, and it measured within the range, but if you skip that step and your toilet happens to be square-shaped or outside these dimensions, you’re going to have a bad time on install day (or have to return it). The 1450W rated power also explains why the instant warm water feature works as well as it does. Rather than storing heated water in a tank, it heats water on demand as it passes through, which is part of why I never noticed any lag between pressing a button and getting warm water.

What Works and What Doesn’t

After a week of real use, here’s my honest, balanced take.

What I liked:

• Heated seat with real temperature control: Four temperature levels mean everyone in my house can set it how they like it, and it’s genuinely nice on cold mornings.
• Built-in water filter: I hadn’t had this on any previous bidet seat, and it’s a thoughtful touch I didn’t know I wanted.
• Warm air drying: I use this every time now, and the adjustable speed levels make it easy to dial in.
• Assisted open/close: The gentle motion on the seat and cover feels more premium than I expected for the price.
• Manual control fallback: Being able to turn off the auto-sensing lid and still control everything from the remote saved us after it startled my daughter.

What could be better:

• Installation documentation: The included photos and video didn’t match how my particular toilet needed to be plumbed, which cost me an extra trip to the hardware store and made me rethink my life choices as a DIY, at-home plumber.
• Unit display inconsistency: Fahrenheit on the seat’s own display but Celsius on the remote is a small but real annoyance I haven’t figured out how to fix.
• Auto-open sensor tuning: The distance adjustment for the presence sensor isn’t intuitive, and the manual doesn’t explain it well.
• No plumber’s tape included: While this is definitely a nice-to-have, it would be easy enough to include with the installation hardware and would potentially eliminate small leaks (or another trip to the hardware store).

Overall, none of these issues were dealbreakers for me. The plumbing documentation gap is the one I’d flag most, since it could genuinely confuse someone installing their first bidet seat, but everything else falls into the category of minor quirks rather than real problems.

Where to Buy and What the Sanyipace Smart Bidet Costs

The Sanyipace Smart Bidet (SU01B) normally retails for $299.99, and it’s currently on sale on the Sanyipace website for $239.99. You can also find it via my Amazon affiliate link if you’d rather order from Amazon at the same price.

If you order directly from Sanyipace, use my code “HTD15″ at checkout for an extra 15% off (for orders over $200, which this bidet qualifies for). Given that this seat includes a heated seat, warm air dryer, water filter, and aromatherapy deodorizer in a single unit, I think the sale price puts it in a reasonable spot compared to other smart bidet seats I’ve tested over the years.

Common Questions About the Sanyipace SU01B

Final Thoughts on the Sanyipace Smart Bidet

After a week of daily use with my whole family cycling through it, the Sanyipace SU01B is now pretty well established. The heated seat and warm air dryer get used constantly; the built-in filter is a feature I didn’t know I should have; and the install, while it had a hiccup or two, wasn’t anything that a quick hardware store trip and consultation couldn’t solve.

If you’re replacing an aging or broken bidet seat like I was, or you’re looking to replace those cold, boring, regular toilet seats and want something that covers the comfort basics well, I think the Sanyipace SU01B is worth considering, especially at the current sale price. If you’re in an older home, just go in expecting that your plumbing might not match the documentation exactly, and have a backup plan for adapters.

Have you installed a bidet seat before? I’d genuinely like to hear what plumbing surprises you ran into; drop a comment or reach out on social media. I’ll keep testing this one over the coming weeks and will update this review if anything changes.

HTD says: The Sanyipace Smart Bidet (SU01B) turns cold, dreaded 3 am bathroom trips into a non-event, and once you’ve got a heated seat and warm air dryer, there’s no going back to plain porcelain. And you get a much better cleaning experience than just using regular toilet paper.
