Learn about key features like TOTO EWATER technology, remote-controlled bidets, and the bidet compatibility across different models. Compare the latest TOTO Washlet models with ease.
Which TOTO Washlet Bidet Seat Should I Buy?
Choose S7A for the most complete hands-free setup, S7 for a premium TOTO Washlet bidet seat without automatic open and close, S5 or S2 for strong comfort at a lower current price, and A2 for a simple elongated-toilet upgrade.
The main buying filters are seat shape, auto flush compatibility, auto open/close lid, remote control versus arm control panel, warm air dryer, PREMIST, EWATER+, night light, current price, and warranty.
Heated seats and warm-water cleansing appear across the TOTO Washlet models, while remote control, deodorizer, CLEAN RESIN, and night light vary by model.
For most bathrooms, the easiest washlet comparison is to match the toilet first, then compare the key features you will use daily.
Use this TOTO Washlet comparison chart as a toilet-fit first guide.
If a TOTO Washlet does not match your toilet shape, it is not the right bidet seat. The chart helps sort fit, cleaning features, dryer features, auto flush, WASHLET+ compatibility, night light, and warranty.
Quick shortlist:
- Choose S7A for automatic open and close plus premium features.
- S7 for the same premium family without automatic open and close;
- KS6 for an elongated toilet with remote control, PREMIST, EWATER+ wand cleaning, CLEAN RESIN, and warm air dryer;
- S5 for a mid-range remote-control model;
- S2 for a lower-price arm-control model;
- KC2 for elongated/round fit with simpler side controls and warm air drying; and
- A2 for the simplest elongated option.
Once you have a shortlist, compare each TOTO Washlet model against your toilet.
S7A and S7 lead the premium tier, S5 and S2 suit mid-range buyers, and KC2 or A2 work when fit and simpler features are acceptable. This keeps a comparison practical across different models instead of turning it into a feature-count exercise.
Which TOTO Washlet Models and Key Features Are Best Overall?
S7A is the best overall TOTO Washlet for the fullest hands-free feature set. Review the TOTO Washlet comparison chart to see how S7A stacks up against every other model at a glance.
S7 keeps many of the same premium features without the automatic open and close lid, making it the stronger premium-value pick when auto open and close are not deal-breakers.
The key difference is simple: S7A adds automatic open and close, while S7 keeps premium clean, comfort, remote control, dryer, PREMIST, EWATER+, and night light features without the automatic lid.
Which TOTO Washlet Bidet Seat Offers the Best Value for Premium Features?
TOTO Washlet S7 is the best premium-value pick if you want an advanced TOTO Washlet bidet seat but do not need automatic open and close.
S7A is the more complete hands-free option; S7 keeps the premium clean, comfort, remote control, and warm water experience at a lower tier.
That difference matters when comparing TOTO Washlet models, and the TOTO Washlet comparison chart makes that side-by-side distinction easy to see.
Choose S7A for hands-free convenience. Choose S7 if you want the premium feature set without the higher price.
When Should I Choose the TOTO Washlet KS6 Bidet Seat?
Choose KS6 if you want strong hygiene features without moving up to S7/S7A.
Premier Bidets lists KS6 with remote control, four user presets, continuous warm-water cleansing, warm air dryer, heated seat, automatic deodorizer, soft nightlight, PREMIST, EWATER+ wand cleaning, CLEAN RESIN, WASHLET+ compatibility, and DIY-friendly installation with a nearby GFCI outlet. Check the TOTO Washlet comparison chart to confirm KS6 is the right fit before purchasing.
KS6 is not right if you need a round seat, an automatic open/close lid, or the S7/S7A auto-flush-kit path.
When Should I Choose the TOTO Washlet S5 Bidet Seat?
Choose TOTO Washlet S5 if you want a mid-range TOTO Washlet bidet seat with remote control and core comfort features.
S5 includes four user memory settings, heated seat, tankless instantaneous water heater, warm air dryer, EWATER+ wand cleaning, PREMIST, automatic deodorizer, seamless seat, and night light.
The TOTO Washlet comparison chart shows S5 clearly positioned between the entry-level and premium tiers.
S5 is not an auto flush, auto open/close, or EWATER+ bowl-rinse model. It is a practical choice if you want strong everyday features without S7/S7A automatic upgrades.
When Should I Choose the TOTO Washlet S2 Bidet Seat?
Choose TOTO Washlet S2 if you want a lower current price with a strong core feature set.
S2 uses an arm control panel rather than a remote control and includes adjustable water temperature, spray position and pressure, oscillating and pulsating cleanse, night light, docking station, instantaneous water heating, EWATER+ wand cleaning, and PREMIST.
S2 is not an auto flush, auto open/close, remote-control, or EWATER+ bowl-rinse model. It fits those people who want a capable TOTO Washlet below the S7/S7A price range. Use the TOTO Washlet comparison chart to weigh S2 against S5 for other features.
When Should I Choose the KS2 Toto Washlet Bidet Seat?
Choose the KS2 if you want a step up from entry-level with a well-rounded feature set. It's available in round and elongated shapes with an arm control panel for easy side-mounted operation. You get an instant water heater, oscillating and pulsating spray, adjustable water temperature and volume, a 3-setting warm air dryer, a heated seat, a night light, SoftClose seat and lid, a docking station, TOTO's CLEAN RESIN coating, and auto energy saver mode.
Note that the KS2 skips EWATER+ wand cleaning, PREMIST bowl spray, and automatic deodorizing. If you want those hygiene extras, look at the S2 instead. If you want a comfortable, feature-rich seat without the extra sanitizing tech, the KS2 is a strong middle-tier pick.
When Should I Choose the Toto Washlet S1 Bidet Seat?
Choose the S1 if you want the simplest, most affordable way into a TOTO Washlet with instant water heating. It's available in round and elongated shapes with an arm control panel, and covers the core Washlet experience: oscillating and pulsating spray, adjustable water temperature and volume, a heated seat, SoftClose seat and lid, a docking station, CLEAN RESIN coating, and auto energy saver mode.
The S1 skips the warm air dryer, night light, EWATER+, PREMIST, and deodorizing. Think of it as comparable to our current A2 model, but with instant water heating instead of a tank heater, so there's no wait for warm water. It's the most straightforward Washlet upgrade with better heating tech than our older entry model.
Which TOTO Washlet Models Have the Auto Flush Feature?
S7A and S7 are auto-flush-kit candidates, not models with universal built-in auto flush. We sell compatible TOTO auto-flush kits for S7A/S7 setups; KS6, S5, S2, KC2, and A2 should not be chosen for auto flush.
If auto flush is a must-have, start with S7A and S7, then confirm the toilet, single-flush or dual-flush kit, and WASHLET+ compatibility. Auto flush depends on the correct TOTO setup and a separately sold kit.
Which TOTO Washlet Models Have Auto Open and Auto Close?
Choose S7A if auto-open and close are must-haves. S7 has many of the same premium features as S7A but without the automatic open and close lid, so this is the practical S7A vs S7 difference.
For the most hands-free experience, compare S7A first. If auto open/close is not important, S7, S5, S2, and KS6 may offer enough comfort at a lower tier.
Which Toto Washlet Models Have Self-Cleaning Wand, Premist, and Ewater+ Key Features?
For the strongest cleaning and hygiene feature set, start with S7A and S7. Their product pages support EWATER+ cleaning for the wand and bowl area, plus PREMIST, deodorizer, remote control, and advanced water heating features.
Premier Bidets also supports PREMIST and EWATER+ wand cleaning for KS6, S5, and S2.
Which TOTO Washlet Bidet Seats Fit Elongated or Round Toilets?
S7A, S7, S5, S2, and KC2 are suitable for elongated/round toilets. KS6 and A2 are current elongated-only picks.
Make the seat shape your first buying filter to ensure you get the right fit, then build around that with features you want.
Which TOTO Toilet Models Have a Night Light?
For a night light, prioritize S7A, S7, KS6, S5, and S2.
S7A and S7 offer the most premium nighttime experience.
KS6, S5, and S2 are practical choices when you want a night light but do not need auto-open and close.
Choose KC2 for simpler controls, heated seat comfort, and value, not for night light.
How should I use this TOTO Washlet comparison chart to compare remote control, controls, and different models?
Before buying, confirm toilet shape, current price, color, availability, installation requirements, warranty, and any TOTO toilet or kit dependency. Use the TOTO Washlet comparison chart to narrow the field, then use the product page for exact fit and purchase details.
Use the TOTO Washlet comparison chart as a starting point, then compare the controls you will use every day. S7A, S7, KS6, and S5 use a remote control, while S2 and KC2 use an arm control panel. For remote control convenience and user presets, compare S7A, S7, KS6, and S5 first. For simple side controls, compare S2 and KC2. Remote control matters most in a shared bathroom, while an arm control panel can be easier when space is tight.
The TOTO Washlet comparison chart also helps compare warm water settings, air temperature control, soft rear cleanse, oscillating cleanse, pulsating cleanse, CLEAN RESIN, Cotton White, Sedona Beige, optional auto flush kit requirements, older models, and installation needs. Use it to decide which features matter before you purchase, including whether an air dryer or a warm air dryer is worth prioritizing.
For color and fit, compare the Cotton White and Sedona Beige options on the individual TOTO product page. For installation, check the GFCI outlet needs, toilet fit, and whether WASHLET+ will keep cords less visible. Use the Toto Washlet comparison chart to narrow the choice, then check the current product page.
If you are replacing the whole toilet, we also sell TOTO one-piece and two-piece WASHLET+ toilet combinations.
