1. TOTO WASHLET G5A Integrated Smart Toilet (MS7631CEMFG#01)
The TOTO WASHLET G5A is TOTO’s latest mid-range integrated smart toilet — the direct successor to the beloved G450 — and it brings a meaningful upgrade to anyone who wants the full smart toilet experience without climbing into the Neorest price tier.
It combines TOTO’s signature TORNADO FLUSH system, CEFIONTECT ceramic glaze, PREMIST bowl wetting, and EWATER+ wand sanitization into one compact, ADA-compliant, elegantly skirted one-piece unit that installs in any bathroom with a standard 12-inch rough-in and a nearby GFCI outlet.
Features
- TORNADO FLUSH system with 1.2 / 1.0 GPF dual-flush efficiency
- CEFIONTECT ion-barrier ceramic glaze keeps the bowl cleaner longer
- PREMIST automatically wets the bowl before each use
- EWATER+ electrolyzed water cleans the wand after every use
- Instantaneous water heater — unlimited warm water, no tank to run dry
- Auto open/close lid and auto flush with manual backup for power outages
- Five wash modes: rear, soft rear, front, wide front, oscillating and pulsating
- Heated seat with five temperature settings, warm air dryer, automatic deodorizer, and night light
- 2 user memory presets; wireless remote control included
- ADA-compliant Universal Height; 3-year residential warranty
Pros
- Outstanding value for a fully integrated TOTO smart toilet
- Compact skirted silhouette fits beautifully in any modern bathroom
- Instant, unlimited warm water is a genuine upgrade over tank-heater seats

If you want a genuinely complete integrated smart toilet experience with TOTO’s world-class engineering at the most accessible Neorest-adjacent price point, the G5A is exactly what you’ve been looking for. It handles everything — flushing, washing, drying, and deodorizing — without a single extra part to buy.

2. TOTO Neorest RS Integrated Smart Toilet (MS8341CUMFG#01)
The TOTO Neorest RS is the entry point into TOTO’s legendary Neorest family — and it’s a remarkably refined toilet at that.
Its smooth, curved silhouette with soft-cornered lines was designed to harmonize with a wide variety of interiors, from minimalist to transitional, making it one of the most versatile-looking smart toilets on this list while still packing in the full Neorest hygiene stack.
Features
- TORNADO FLUSH with ultra-efficient 1.0 / 0.8 GPF dual-flush

The Neorest RS is the right pick if you want the full Neorest Clean Synergy package — EWATER+ bowl coverage, PREMIST, and CEFIONTECT — in a timeless, organically styled package. If you’re deciding between this and a premium bidet seat, our highest-rated bidet toilets guide covers how the RS compares across the broader integrated toilet landscape.

3. TOTO Neorest AS Integrated Smart Toilet (MS8551CUMFG#01)
The TOTO Neorest AS sits one step above the RS in the Neorest lineup, and the upgrade shows in the more refined silhouette and expanded feature set — particularly the four-user memory system that makes this model ideal for busy family bathrooms.
It shares the same clean-synergy hygiene stack as the RS — EWATER+ on both wand and bowl, PREMIST, CEFIONTECT, and TORNADO FLUSH — but wraps it in a slightly more architectural form and includes a wider water surface for a more powerful, efficient flush.
Features
- TORNADO FLUSH with 1.0 / 0.8 GPF dual-flush efficiency
- Full EWATER+ coverage for both toilet bowl and bidet wand after every use
- PREMIST bowl wetting and CEFIONTECT ceramic glaze as standard
- Auto open/close proximity-sensing lid; auto flush with manual override
- Instantaneous water heater — continuous warm water, zero wait time
- Five wash modes with oscillating and pulsating spray; adjustable pressure and temperature
- 4 user memory presets, heated seat with 5 temperature settings
- Warm air dryer (5 settings), automatic deodorizer, ambient night light
- ADA-compliant Universal Height; 3-year residential warranty
Pros
- Four user presets — perfect for households with multiple regular users
- Neorest-tier Clean Synergy keeps the entire toilet self-sanitizing
- Refined architectural shape strikes a strong visual statement in any bathroom
- Ultra-high-efficiency 0.8 GPF option is among the most water-conservative on this list
- Rock-solid 3-year residential warranty backs TOTO’s engineering confidence
Cons
- Significant investment — positioned at the upper tier of the Neorest range
- Two-component shipping means white-glove or professional installation is strongly recommended
- Not the most compact footprint — measure your rough-in carefully before ordering
The Neorest AS is the smart choice for buyers who want TOTO’s flagship smart toilet experience with four personalized user profiles and the complete Clean Synergy hygiene system working in unison. It’s also a popular pick among buyers considering age-in-place features; our guide to the best bidets for seniors explains why hands-free integrated toilets make such a practical long-term investment.

4. VOVO Stylement TCB-090SA Smart Bidet Toilet
The VOVO TCB-090SA is the most fully automated smart toilet on this list outside the TOTO Neorest range, and it delivers a genuinely impressive feature set at a price point well below the premium Japanese brands.
Made in South Korea and engineered for modern bathrooms, the TCB-090SA features a distinctive square design with a wider-than-average seat, UV-A LED nozzle sterilization, motion-sensing auto open/close lid, and a powerful tankless tornado flush that connects directly to your home’s water supply — no tank required.
Features
- Tankless design connects directly to water supply — powerful dual-flush at 1.12 GPF
- UV-A LED nozzle sterilization for extra hygiene assurance between uses
- Motion-sensing auto open/close lid and auto dual flush triggered by occupancy detection
- 3-in-1 full stainless steel nozzle with posterior, feminine, and vortex modes
- Warm water wash with adjustable temperature and pressure (5 levels)
- Heated wider seat with 3 temperature settings and 24-hour power-save mode
- Warm air dryer (3 temperature settings); automatic deodorization system
- Soft LED night light; wireless remote control with wall mounting included
- Available in white and matte black; cUPC/cETLus certified; made in Korea
Pros
- UV-A LED sterilization adds a hygiene dimension most competitors skip
- Striking square design stands out in contemporary bathrooms
- Wider seat is noticeably more comfortable for taller and larger users
- Excellent value for a fully integrated, fully hands-free smart toilet
- Available in matte black — a rare finish option in this category
Cons
- 1-year warranty on the seat assembly (3-year coverage applies to the ceramic bowl only)
- Water pressure must be within spec (40–75 PSI) — homes with very high pressure need a regulator
- Square bowl design may not suit users accustomed to traditional elongated shapes
The VOVO TCB-090SA is the ideal pick if you want a completely hands-free, modern smart toilet experience with UV sterilization and a bold design at a significantly lower price than the Neorest tier. It’s one of the highest-rated bidet toilets in its category among real-world owners and is a consistent standout in any comparison of toilets with bidet built in.

5. Kohler Innate One-Piece Smart Toilet (K-29777-PA-0)
The Kohler Innate is Kohler’s most accessible fully integrated smart toilet, and it brings a surprisingly complete feature set to buyers who want a trusted American brand name in an all-in-one smart toilet format.
It features Kohler’s signature ReadyLock installation system — a patented skirted-toilet mounting solution that eliminates the need to drill into the floor — making it by far the easiest integrated smart toilet on this list to install without professional help.
Features
- Dual flush: 1.0 GPF for light waste, 1.28 GPF for full flush — WaterSense certified
- Pre-use bowl mist for cleaner waste removal with each flush
- Integrated stainless steel bidet wand with UV light sanitization after every use
- Adjustable spray shape, position, pressure, temperature, pulsate, and oscillate functions
- Motion-activated auto open/close lid; automatic flush with convenient manual backup
- Heated seat; warm air dryer; soft night light for low-disruption nighttime visits
- Patented ReadyLock installation — no floor drilling required for standard 12″ rough-in
- Comfort Height seating (chair height) — ADA-accessible
- AC power required; sleek fully skirted one-piece design in white
Pros
- ReadyLock system makes DIY installation genuinely achievable without a plumber
- UV light wand sterilization is a standout hygiene feature at this price point
- Trusted Kohler brand with widespread service and parts availability
- WaterSense certified — real water savings without sacrificing flush performance
- Clean, compact one-piece design blends into any contemporary bathroom aesthetic
Cons
- Only 1 user preset — not ideal for households with very different preferences
- 1-year limited warranty is shorter than TOTO and VOVO competitors
- Fewer wash mode options compared to TOTO’s Neorest and G5A lineup
The Kohler Innate is the right choice if you want a reputable, feature-complete integrated smart toilet that you can install yourself without a plumber, backed by Kohler’s nationwide service network. It’s a particularly smart pick for first-time integrated toilet buyers who want a lower-risk entry into the category. If you want to understand how it stacks up against premium bidet seats before committing, our bidet toilet vs bidet seat comparison lays out the key differences clearly.

How to Choose the Best Integrated Smart Toilet for You
Focus on three things: hygiene tech, installation requirements, and user count. For maximum self-cleaning autonomy, prioritize EWATER+ or UV sterilization. For multi-person households, choose a model with at least 4 user presets. Always confirm your rough-in measurement is 12 inches, and ensure a GFCI outlet is within reach before ordering.
Tips for Getting the Most From Your Integrated Smart Toilet
Install a surge protector between the wall outlet and your smart toilet’s power cord — power surges can damage the electronic components and void warranties on some models.
Set your home water pressure to between 40 and 75 PSI before installation, particularly for tankless models like the VOVO TCB-090SA — pressures outside this range can cause leaks or reduced performance.
Use the ECO mode or energy-saving scheduler on your smart toilet — most models can learn your usage patterns and automatically reduce seat heating and standby power during hours you’re rarely in the bathroom, saving meaningful energy over time.
Don’t use bleach-based cleaners on the toilet bowl or seat — EWATER+ and UV sterilization systems are designed to maintain hygiene without harsh chemicals, and bleach can degrade plastic and seal components over time.
Register your toilet for warranty coverage immediately after installation — this is especially important for TOTO Neorest models where the 3-year residential warranty requires registration to be valid.
Check the nozzle position settings when you first set up your smart toilet — most users find the factory default position works well, but a quick adjustment of one or two levels can make a significant difference in comfort for shorter or taller users.
Frequently Asked Questions
Do integrated smart toilets require professional installation?
Most do — particularly TOTO Neorest models, which ship in two components and require a plumber to connect the water supply and ensure proper seal integrity.
The Kohler Innate is the notable exception: its patented ReadyLock system eliminates the need to drill into the floor, making a confident DIY installation achievable for most homeowners with basic plumbing skills.
Regardless of which model you choose, you’ll need a GFCI outlet within approximately 4 feet of the toilet. If your bathroom doesn’t have one, factor in the cost of having an electrician add one before you order.
Are integrated smart toilets more hygienic than adding a bidet seat?
In practical terms, yes — an integrated smart toilet is engineered as a single system, which means the bowl, the wand, and the flushing mechanism are all designed to work together.
Models with EWATER+ bowl misting (like the TOTO Neorest RS and AS) keep the entire interior of the bowl sanitized between uses, which no bidet seat can replicate since those only clean the wand.
Our bidet toilet vs bidet seat guide walks through the hygiene differences in detail if you’re still deciding between the two approaches.
Can integrated smart toilets fit most bathrooms?
Yes — all five toilets on this list use a standard 12-inch rough-in and an elongated bowl footprint, which fits the vast majority of US bathrooms without modification.
Measure from the finished wall behind your toilet to the center of the floor drain before ordering. You’ll also want at least 15 inches of clearance on each side of the toilet and 21 inches of clear floor space in front of the bowl. All models on this list are ADA-compliant Universal or Comfort Height, making them accessible for adults of all mobility levels.
What is the most water-efficient integrated smart toilet?
The TOTO Neorest RS and Neorest AS are the most water-efficient options on this list, offering a light flush option of just 0.8 GPF — significantly below the EPA WaterSense standard of 1.28 GPF.
Over a year of regular use, this can save thousands of gallons of water per household compared to a standard toilet. The TOTO WASHLET G5A follows closely at 1.0 GPF light flush, while the Kohler Innate and VOVO TCB-090SA are WaterSense certified at their respective consumption levels. For more on how bidets reduce both water and paper waste, our guide on bidets with warm water and dryer covers the eco-friendly advantages in detail.
Conclusion
The best integrated smart toilet for you comes down to what you prioritize most.
If you want TOTO’s world-class engineering at the most accessible price point, the TOTO WASHLET G5A delivers the full smart toilet experience with TORNADO FLUSH, PREMIST, and EWATER+ wand cleaning in a beautifully compact package.
If bowl-level self-cleaning is non-negotiable, step up to the TOTO Neorest RS or TOTO Neorest AS — both add EWATER+ bowl misting to the full Neorest Clean Synergy stack, with the AS adding 4 user presets for multi-person households.
If you want UV sterilization, a bold modern design, and a lower price than the Neorest range, the VOVO TCB-090SA consistently punches above its weight with real-world owners.
And if DIY installation is a priority, the Kohler Innate‘s ReadyLock system makes setup genuinely achievable without hiring a plumber.
Whichever you choose, you’re making a long-term upgrade to your bathroom’s hygiene, comfort, and daily experience.
