The Bathroom Upgrade You Didn’t Know You Desperately Needed
I’ll be honest — I’ve tested enough bidet seats to have opinions that make me genuinely annoying at dinner parties. Most of them follow the same formula: chunky profile, plasticky feel, a remote that looks like it was designed by someone who’s never seen a human hand. Then the Ultra Nova showed up on my toilet, and I had to recalibrate a few things.
Nova Bidet’s flagship model doesn’t just claim to be the slimmest bidet seat on the market — it actually is, sitting at a jaw-dropping 3.66 inches tall at its highest point. I spent several weeks putting every feature through its paces, and what I found confirmed some of the boldest claims I’ve seen in this category. Here’s what you need to know before buying.
Quick Verdict
| Key Points | Verdict |
|---|---|
| Best for | Homeowners who want the full luxury bidet experience — slim profile, enema wash, hands-free operation — in one package |
| Not ideal for | Round toilet owners, those on a tight budget, or anyone with a lever-flush toilet hoping for auto-flush |
| Aiden’s Rating | 8.7 / 10 |
Pros:
- Thinnest profile of any bidet seat currently on the market
- Best-in-class enema wash — genuinely impressive
- Radio frequency remote works through walls, towels, and bathroom chaos
Cons:
- Auto-flush feature limited to top-flush toilets only
- Elongated size only — no round toilet option
- Dryer is effective but takes a patient minute or two
Key Features of Ultra Nova — What Nova Bidet Claims to Offer
1. Ultra-Slim 3.66-Inch Profile
The spec that stops people mid-scroll. At just 3.66 inches at its tallest rear point, the Ultra Nova is — by a measurable margin — the slimmest bidet seat available. For context, the TOTO S7A Washlet (the longtime class leader) sits at 4.06 inches. That gap may not sound like much, but it translates to noticeably more usable seat space and a more natural sitting position. The lipless lid design means nothing is digging into your back when you sit upright, either.
2. Ceramic Instant-Type Variable Frequency Inverter Heating System
This is the system responsible for the Ultra Nova’s “unlimited warm water” claim. Unlike tank-based heaters that run out after 30–45 seconds, the ceramic instant-type heater provides continuous warm water at your set temperature for as long as the wash runs. Water temperature is adjustable between 86°F and 102°F. For a bidet at any price, inconsistent water temperature is the single most jarring experience — this system eliminates the problem entirely.
3. Air Bubble Induction Pump
Nova infuses the spray with micro air bubbles before it reaches you, which softens the feel of the stream without reducing cleaning effectiveness. The result is a wash that’s thorough without being aggressive — an important distinction for anyone with sensitive skin, post-surgery recovery needs, or simply a preference for not being power-washed.
4. Silver-Nano Sterilization with On-Demand Self-Cleaning
The nozzle is coated with silver-nano antibacterial material, and instead of running random cleaning cycles throughout the day (which can startle guests who thought they were alone in the bathroom), the Ultra Nova runs its self-cleaning cycle on-demand — precisely when you initiate a wash. The internal tubing also features silver-nano coated lining to inhibit microbial growth at the source. Hygiene at the structural level, not just on the surface.
5. Radio Frequency Remote with Side Controls
The stainless steel remote operates on radio frequency rather than infrared. This matters more than it sounds. Infrared remotes require line-of-sight — meaning a towel rack, an oddly positioned toilet roll holder, or an enthusiastic bathroom cabinet door can interrupt the signal. The RF remote works regardless. As a backup (or for guests who’ve wandered off with the remote), a built-in side knob handles all essential functions independently.
My Testing Experience — Ultra Nova Bidet Seat Review
The Seat Comfort Is Legitimately Exceptional
I’ve sat on a lot of bidet seats. Not something I planned as a career detail, but here we are. The Ultra Nova’s combination of its low profile, the D-shaped front opening, and the sheer seating area pushes it to the top of any comfort ranking I’d compile. Sitting far back on the seat feels natural in a way that most other models — which tilt you slightly forward due to their rear bulk — simply don’t manage. The polypropylene construction has zero creak, even under significant weight, and the soft-close lid lands with a quiet authority that makes you feel like you’re in a hotel that actually spent money on the bathroom.
The heated seat warming up between 77°F and 104°F might sound like a small thing until the first time you use this at 6am in January. After that, it becomes non-negotiable.
The Wash Performance Sets a New Bar
Let me talk about the enema wash feature, because it deserves its own conversation. I’ve tested the BioBidet BB-2000 (widely considered a benchmark in this department) and a handful of other premium seats that claim enema functionality. The Ultra Nova’s enema wash is the most precisely targeted, effectively pressured version I’ve encountered. It does what it’s supposed to do — with no ambiguity about whether it worked. For anyone managing chronic constipation, post-surgery recovery, or digestive health conditions, this isn’t a novelty feature — it’s a legitimate medical tool in a remarkably elegant package.
The hot/cold massage wash was, I’ll admit, something I expected to use once and immediately disable. The alternating warm-to-cool cycling across sensitive tissue is not something you’d describe to someone at a dinner party, but it delivers a soothing, genuinely spa-like experience that I ended up leaving on. Staff at ManyBidets — people who test bidets for a living — reported the same thing: initial skepticism, followed by genuine affection for the feature. I’m in the same boat.
Standard rear and front wash performance is strong across all pressure levels. The air bubble induction pump gives the spray a softer, enveloping quality versus the sharp stream you get on seats without it. High-pressure setting delivers real cleaning power; the low end is gentle enough for post-procedure use.
The RF Remote Is the Detail That Changes Everything
I’ve used enough infrared-controlled bidet seats to appreciate what radio frequency actually means day-to-day. You can mount the remote on the wall at a standard height, leave a hand towel on the rack between you and the seat, position yourself however is comfortable, and the signal still goes through cleanly. No pointing, no repositioning, no accidental cold bursts because the signal didn’t read. The stainless steel build quality of the remote also deserves a mention — it feels like it belongs in a premium bathroom, not like it was salvaged from a universal TV remote drawer.
The two programmable user presets are genuinely useful for a household where more than one person has opinions about water temperature and pressure (which is most households, once people discover bidets). Set it, save it, forget it.
Auto Open/Close Lid — A Feature That Turns Into a Habit
The lid opens when you walk in. It closes when you walk away — seat included. Once you’ve lived with this for about four days, manually lifting a toilet lid at someone else’s house starts to feel mildly prehistoric. The hands-free functionality is particularly valuable for elderly users or anyone with mobility limitations. The proximity sensor range is adjustable, so it won’t trigger every time someone walks past the bathroom door.
The discreet self-cleaning cycle — triggered precisely when you initiate a wash rather than randomly throughout the day — is one of those thoughtful engineering decisions that matters in a shared bathroom. It runs quietly, does its job, and doesn’t announce itself to guests who aren’t yet aware they’re using a bidet.
The Dryer — Effective, With Patience
The warm air dryer covers a temperature range from room temperature up to 131°F and does a reliable job with one caveat: you need to give it time. Two to three minutes gets you fully dry. If you’re the type of person who finishes a wash and immediately expects the dryer to handle everything in 60 seconds, you’ll want to keep a few sheets of tissue nearby for the final step. This is an industry-wide limitation of bidet seat dryers — not a specific Ultra Nova shortcoming — but it’s worth being honest about rather than glossing over.
How It Compares — Ultra Nova vs. Alpha UX Pearl
The Alpha UX Pearl is the natural comparison here — it’s similarly priced at around $599, named Yahoo Shopping’s Best Overall Bidet of 2026, and frequently recommended alongside the Ultra Nova.
The Ultra Nova wins clearly on physical profile (3.66″ vs 4.5″ rear height), seating space, and wash versatility. The enema wash alone is a decisive differentiator — the UX Pearl has no equivalent function. The hot/cold massage wash is Ultra Nova-exclusive in this tier. The RF remote beats the UX Pearl’s standard remote for reliability in real-world bathroom layouts. And the auto-opening sittable lid is a feature the base UX Pearl doesn’t offer (only the upgraded UXA Pearl Auto adds it, at additional cost).
The Alpha UX Pearl wins in one meaningful area: built-in bowl deodorization. Its photocatalytic “Pure Breeze” system neutralises odours between uses without requiring replaceable cartridges. The Ultra Nova doesn’t offer a bowl deodorizer. The UX Pearl is also available in round bowl configuration, which matters to a substantial number of households.
Bottom line: If enema functionality, a thinner profile, and hands-free lid operation are priorities, the Ultra Nova is the stronger choice. If bowl deodorization matters and your toilet is round, the Alpha UX Pearl has specific advantages that make the choice straightforward.

The Real Cons — What Aiden Didn’t Like
Auto-flush requires a top-flush toilet. The Ultra Nova+ model includes a patented auto-flush system, which sounds excellent until you read the small print: it only works with top-button flush toilets. Side-lever toilet? You won’t see this feature in action. This is worth confirming before you choose the Plus model specifically for auto-flush.
Elongated only. The Ultra Nova is currently only available in elongated bowl configuration. Households with round toilets are simply not catered for — full stop.
The seat sensor placement requires full-seated contact. The skin-contact sensor is positioned toward the front-left of the seat. For very young children (roughly under 8), staying far enough forward to keep the sensor engaged through a full wash cycle can occasionally be inconsistent, causing the cycle to pause mid-use. Not a problem for adults or older children, but worth being aware of in a family setting.
Installation snap-on can require a firm hand. Most users report a smooth 20–30 minute DIY install. A handful find the final snap onto the mounting plate needs more force than they expected before it clicks into place. Not a technical problem, just not quite as seamless as the packaging confidence might lead you to expect.
Who Should Buy This — And Who Shouldn’t
The Ultra Nova is the right seat for you if you want the most feature-complete luxury bidet experience in the current market without stepping up to a $1,500+ integrated smart toilet. It’s particularly well-suited for large adults who appreciate the wide, deep seating surface; anyone managing specific health conditions (constipation, post-op recovery, haemorrhoids); households where two people have different wash preferences who will both love the user presets; and anyone who values design enough to care that their bidet doesn’t look like a medical device.
The Ultra Nova will disappoint you if you have a round toilet bowl (it simply won’t fit), if you need the auto-flush function but have a lever-flush toilet (it won’t work), or if you’re comparison-shopping in a tight price bracket and expect basic functionality — this seat is unapologetically a luxury product with a luxury price to match.
Final Verdict
The Ultra Nova earns its position as one of the most impressive bidet seats on the market today. The 3.66-inch profile is not marketing fluff — it’s the industry’s thinnest, and it translates to a noticeably more comfortable sitting experience that buyers who’ve used multiple premium seats consistently single out. The enema wash outperforms competitors I’ve specifically tested for this feature. The radio frequency remote removes the daily friction that makes other bidet seats mildly annoying to use long-term. And the auto-opening, sittable lid with hands-free close is the kind of feature that becomes invisible once you have it — until you visit someone else’s bathroom.
With a 3-year full warranty and a 60-day risk-free trial, Nova Bidet is clearly confident in what they’ve built — and based on my time with it, they’ve earned that confidence. If you’re in the market for a genuine luxury bidet upgrade and your toilet is elongated, this should be at the top of your shortlist.

FAQ
1. Does the Ultra Nova work on all toilets? The Ultra Nova fits most standard elongated 1-piece and 2-piece toilets. It does not come in a round bowl configuration, so if your toilet has a round bowl, you’ll need to look at a different seat. Before purchasing, verify that your bolt holes are between 4.5″–7″ apart and that your tank meets the bowl at a roughly 90-degree angle.
2. What’s the difference between the Ultra Nova and the Ultra Nova+? The Ultra Nova+ adds a patented auto-flush system that integrates with your toilet’s flush mechanism. Critically, this feature only works with top-button flush toilets — not lever-flush models. All other features are identical across both versions.
3. Does the Ultra Nova require professional installation? No. Most users complete installation in 20–30 minutes using included hardware and a basic wrench. The main requirement is a standard GFCI electrical outlet near the toilet. If you don’t have one, that portion would require an electrician, but the bidet seat itself is straightforward DIY.
4. How does the self-cleaning system actually work? Rather than running automatic cleaning cycles throughout the day (which can be surprising and unnecessary), the Ultra Nova’s silver-nano nozzle sterilization activates precisely when you press the wash button — before and after each use. The internal tubing is also silver-nano coated to inhibit bacteria growth at the source.
5. Is the Ultra Nova good for people with haemorrhoids or post-surgery recovery? Yes, and notably so. The adjustable pressure range, gentle air-bubble infused spray, hot/cold massage wash, and dedicated enema function make this one of the more therapeutically capable bidet seats in its price range. The low spray pressure settings are gentle enough for sensitive tissue, while the enema wash handles cases where more targeted relief is needed.
