An automatic toilet lid closer ends the awkward foot-kick, the germy hand-reach, and the late-night lid slam. These smart seats sense you coming, lift the lid on approach, and close it gently when you step away. You get a cleaner, quieter, more hands-free bathroom experience without ever touching the porcelain.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You want a toilet lid that closes itself, but you are not sure if you need a full bidet seat or just the lid. This breakdown of the automatic toilet lid closer helps you spot the smart-buy winners and avoid the sensor-gimmick flops.
Our Picks at a Glance



How To Choose The Best Automatic Toilet Lid Closer
Your first decision is simple: do you want only the automatic lid, or the whole smart bidet seat? Most automatic closers are built into bidet seats, so you are really choosing between the lid mechanism alone or the full package—lid, heated seat, warm-water wash, and dryer.
Sensor Technology Matters More Than You Think
The lid only works if the sensor reliably detects you. Advanced radar and body-sensing chips are the technology to look for — they detect motion through the whole approach, not just a narrow beam. Some models trigger annoyingly when you walk past the bathroom, so check if the sensor sensitivity can be adjusted or disabled.
Power and Installation Are the Hidden Hurdle
Every automatic lid needs electricity. Before you buy, check whether you have a grounded outlet near the toilet — most models require one, and extension cords rarely work well. Installation is DIY-friendly for most, but a smart toilet with a built-in tank can be a two-person job that takes a couple of hours.

In-Depth Reviews
1. TOTO WASHLET+ S7A Electronic Bidet Toilet Seat
Our pick — over 4.5★ from 70+ verified ratings; the strongest balance of quality and price.
The TOTO WASHLET+ S7A pairs a hands-free auto lid with a spa-grade warm water wash, making it the throne-room upgrade that treats you like royalty.
The S7A’s auto open/close lid uses sensors to raise and lower it hands-free as you approach and depart. What wins people over is the build quality, with 22 owners calling the construction top-tier and the features earning praise from 7 more. It’s the kind of solid engineering you feel the moment you sit down.
The wash experience is where this seat earns its premium status. The AIR-IN WONDER WAVE infuses air into each droplet so the stream feels gentle yet thorough, and the oscillating and pulsating functions let you customize the clean. The remote stores 4 user memory settings, so different household members each get their own preferred water temperature and pressure without re-dialing every time. As owners put it: “This washlet bidet from Toto almost makes me want to buy the matching base for the auto flush feature.”
Installation runs under 30 minutes for most DIYers, though the programming steps can feel complicated — a few buyers found the manual’s instructions hard to follow. The bowl light isn’t on by default, and the lid doesn’t recline far enough for some, neither of which is adjustable. It needs electricity, and it costs a serious premium, but the reliability and clean are hard to argue with for a full-featured flagship.
What earns the crown
- Hands-free auto open/close lid senses your approach and departure
- Gentle yet effective AIR-IN WONDER WAVE oscillating wash
- 4 user memory settings for personalized water control
- PREMIST and EWATER+ keep the bowl and wand hygienic
Where it gets steep
- Premium pricing that demands a real budget
- Bowl light and lid recline angle are not adjustable
- Programming the remote takes patience with the manual
Reach for this if: you want the most trusted, full-featured automatic lid and wash experience money can buy.
Look elsewhere if: your budget stops well short of flagship territory — the value math only works for serious users.
2. Erdoru Luxury Smart Toilet with Tank
The Erdoru is a complete smart toilet with a 1000g MaP flush score, so waste clears in one powerful, clog-free go.
Unlike the seat-only options above, this is a full ceramic toilet replacement. It layers an auto open/close lid with a full-range sensing seat that flushes when you stand, no matter how you sat. That flush muscle is the headline: a MaP score of 1000g means it handles heavy waste efficiently, and the 360° Foam Shield lays down a silky layer to stop splashing, trap odors, and repel stains before they form.
The comfort suite is deep. You get 6 adjustable temperature levels each for water, seat, and air dryer — so you can dial winter warmth or summer cool independently. The front sozzle for feminine wash uses a soft, individual water flow, and the self-cleaning nozzle keeps hygiene up between uses. Owners rave about the appearance — 25 separate mentions — and call it the best value for money, with the powerful yet quiet flush standing out in daily use.
Installation is the real hurdle: it’s a two-person job that can stretch to about 2 hours, and buyers recommend professional help if you’re not handy. The seat sensor needs light-colored shoes to trigger for some, and the remote occasionally drops connection. One unit arrived with a dead lid sensor, though the foot sensor and side button still worked as backups. It’s a big commitment, but for a full smart toilet, it delivers a remarkable feature set.
Best value throne: this gives you auto lid, auto flush, foam shield, and 6-level heating for far less than comparable smart toilets — the catch is the heavier install.
3. Bio Bidet DLS Premium Heated Bidet Seat
The Bio Bidet DLS keeps the smart setup simple, with a one-button auto feature that seniors and tech-averse users genuinely appreciate.
This seat’s auto-open and auto-close handles both the lid and the seat, and the slow-close hinge stops the slamming that wakes the house at night. The wireless remote is refreshingly intuitive — owners describe a single button that handles the auto function, making it an easy daily driver for older family members. Quality gets 12 positive mentions and installation 9, with most DIYers finishing solo in about 30 minutes.
The wash experience centers on a stainless steel nozzle with unlimited warm water and adjustable pressure and temperature for both front and back. A 3-speed warm air dryer and a built-in night light round out the luxury package. The centered sprayer placement turned out to be a comfort winner, with continuous heated water called a key daily feature — it stays warm as long as you need it, never running cold mid-wash.
The honest trade-off is value: several owners feel the price runs high for what it offers, and the seat runs a bit shorter than some TOTO models, which prompted at least one return. It’s a dependable, second-unit repeat buy for many — one owner literally installed a second one in another bathroom. If you want automatic everything without the learning curve, this is the smooth path.
Ease-first choice: the one-button auto feature and 30-minute install make this the gentlest leap into smart bidet territory, if the price tag sits well with you.
4. iliD Heated Bidet Toilet Seat with Remote
The iliD brings radar and body-sensing chip tech to the mid-range, so the lid opens and closes for you without any touch.
This is the design-forward pick: a 32% slimmer profile and 20% larger seat area than standard models, so it looks sleek while giving you more room to sit comfortably — owners describe it as relaxing like a sofa. The radar and body-sensing chip integration is the standout feature, with the lid opening as you approach and closing gently when you leave. A full ABS plastic self-cleaning nozzle ensures hygiene before and after every wash.
The warm water is instant and endless, paired with a 3-level warm air dryer and adjustable temperature and pressure. The self-retracting clean head and oscillating sprayer earn repeated praise, and the night light adds a practical touch for middle-of-the-night trips. Owners consistently highlight the auto-open lid and the heated seat as the features that make the daily routine dramatically better.
Installation is claimed at 3 minutes, but real-world buyers found it takes longer, with tight couplings that may leak without Teflon tape. The air dryer is the weak link — several owners call it nearly useless and just blot with toilet paper instead. The instructions are poorly translated English, which adds friction. If you can look past the dryer, the wash and lid performance make this a strong mid-range value.
What wins people over
- Radar auto open/close works reliably without touch
- 32% slimmer with a 20% larger seat area for comfort
- Self-cleaning ABS nozzle and oscillating sprayer
What falls short
- Air dryer is weak — owners blot with paper instead
- Install takes longer than the 3-minute claim
- Poor English manual makes programming harder
Best for: buyers who want radar-grade auto lid tech and a generous seat without flagship pricing.
Think twice if: a functional warm-air dryer is a must-have for you, since this one underwhelms.
5. Sosh Electric Bidet Toilet Seat With Remote
The Sosh packs a 25% thinner silhouette and a 22% bigger seat area into a mid-range price that still feels like a luxury comfort upgrade.
Sosh’s patented slim profile makes the seat look noticeably less bulky on your toilet, while the larger seating surface adds real comfort — owners describe the feeling as sinking into a sofa. The radar and body-sensing technology opens the lid as you approach and closes it softly when you step away, and the bowl light and quiet operation earn consistent praise. Quality leads the reviews with 25 mentions, and lid operation follows with 18 positive notes.
The wash system delivers endless warm water from an instant-heating system, with a 3-level warm air dryer and adjustable water temperature, spray pressure, and air-dry settings. The self-cleaning ABS plastic nozzle keeps hygiene high before and after each use. The remote is responsive and intuitive, drawing 9 mentions from owners who call it simple to use, and the side knob gives you a backup control that doesn’t require the remote.
The auto-open lid is the one catch: it triggers near a sink, and there’s no off switch to disable it when you don’t want it. The dryer also runs weak — described as a light breeze that needs more time to finish the job. Setup can be challenging if you’re not handy, though the responsive customer support helps sort out T-valve mismatches with a free 3/8″ replacement.
The value balance: this pick gives you radar auto-open (a motion sensor that lifts the lid as you approach), a roomier slim seat, and endless warm water at a price that undercuts bigger-name rivals. Just budget around the weak dryer.
6. BidetMate 3500 Series Smart Bidet Toilet Seat
The BidetMate 3500 is the family-flex pick, with seven wash modes and a lid that holds up to 165 lbs of lean.
This seat pairs the auto open/close lid with a wash system for the whole household: aerated, pulse, feminine, power wash, massage, and child modes, plus 5 pressure settings. The retractable stainless steel nozzle self-cleans between uses and adjusts for front and rear wash. A 3-year warranty with US-based support backs it up, and owners find that genuinely reassuring. Buyers report 24 positive mentions for quality and 12 for installation, making it among the most consistently praised picks here.
The heated seat and warm air dryer mean less toilet paper reliance, and the soft-closing seat stops the night-time slam. The 47-inch grounded power cord gives you some placement flexibility around the outlet. One detail stands out: the lid holds 165 lbs, so it handles leaning without stress. Owners upgrading from the BidetMate 2000 call the 3500 a clear step forward in comfort and function.
Two honest gripes recur. The auto-open triggers every time you enter the bathroom, with no simple way to disable it — one owner wishes for a toggle. Water pressure gets mixed feedback with some finding it low, and the mounting hardware is described as poor. Also, confirm your toilet’s elongated shape and check the 40-50mm clearance from mounting bolts to the tank on flat-back bowls before ordering.
Why families like it
- 7 wash modes cover every user from kids to adults
- Self-cleaning stainless steel UV nozzle adjusts position
- 165-lb lid capacity and soft-close seat
What to plan around
- Auto-open has no off switch — it triggers on entry
- Water pressure reads low for some owners
- Poor mounting hardware and large footprint
Choose this for: a multi-user household wanting wash variety and a warranty that actually backs the product.
skip it if: you want to disable the auto-open near a sink, or your toilet is round rather than elongated.
7. TOTTE Smart Bidet Toilet Seat with Auto Open/Close Lid
The TOTTE brings the auto open/close lid and a heated seat into the entry-level zone, with a permanent filter that never needs replacing.
The headline value here is the built-in stainless steel micro-filter — it traps sediment and impurities so you never buy replacement filters again. The auto open/close lid reduces germ spread, and a 3-level seat warmer keeps things cozy in cold months. Owners single out the warm seat as the favorite feature, and the appearance draws 17 positive mentions, with easy installation praised 9 times.
You get instant thermostatic warm water with posterior, feminine, oscillating, and massage modes, plus a warm air dryer. The self-cleaning nozzles keep hygiene up before every use. The remote controls everything, and a soft LED night light helps navigate dark bathrooms. As one owner put it, “The warm seat is the best!!” — and kids apparently love it too.
The auto-open feature is the most-discussed trade-off: some owners mention the lid not opening properly, and the seat runs 1.5 inches shorter than a standard elongated fit. Leakage gets mixed reviews — some report none, others mention leaks that the seller didn’t resolve. Also note the auto function covers the lid only, not the seat, and the front spray needs a forward lean to hit right.
The budget bridge: you get the hands-free lid, heated seat, and a filter that never costs you again — if the sensor and seal behave in your bathroom.
8. Bazyths Smart Toilet with Bidet Built In Tank
The Bazyths is a full smart toilet with foot-sensor flush and a 1.03 GPF water-saving rinse, built for low-pressure homes.
This one-piece elongated toilet is designed for bathrooms with low or unstable water pressure, thanks to a built-in tank and pressure-assisted flush that stay reliable where others falter. The lid opens as you approach, and both lid and seat close after you leave. A foot sensor lets you open the lid or seat and flush hands-free — no touching, no reaching. The power-off flush battery compartment means you can still flush during an outage.
The comfort features match pricier units: instant warm water for rear and feminine wash, an adjustable heated seat, a warm air dryer, and a self-cleaning nozzle that detaches for easier maintenance. The siphon jet and pressure-assisted system deliver a deep rinse while using just 1.03 GPF. Quality leads with 18 positive mentions and design with 8, with owners calling it feature-rich at a price that can’t be beat.
The recurring concern is durability — a few customers note leaks developing after a few months of use. The auto open/close runs slower than pricier models, which is noticeable if you’re used to snappier sensors. You’ll need a GFCI outlet nearby, and installation is a standard 12-inch rough-in fit. Customer service gets high marks, with one owner getting a free remote replacement even after the warranty expired.
The affordable full-package: foot sensor, heated seat, and warm wash in a complete toilet — just factor in the slower sensor and occasional leak reports.
Understanding the Specs
Radar vs. Standard Sensors
The sensor is the brain of any automatic lid. Radar and body-sensing chips detect motion across a wider field, so the lid opens reliably as you approach rather than missing you. Basic passive infrared sensors can be narrower and more prone to false triggers when you walk past the bathroom door. If the auto-open seems twitchy or misses you, a model with radar tech is the upgrade path.
Heated Seats and Warm Air Dryers
These two features turn a basic lid into a daily comfort upgrade. A heated seat with multiple temperature levels keeps winter trips bearable. A warm air dryer reduces toilet paper reliance, though not all dryers perform equally — some owners describe the airflow as a weak breeze, so check whether a model has a 3-level dryer if this matters to you. Both need electricity, so confirm you have a grounded outlet near the toilet.
