It is easy to overspend on bathroom luxury. Separating the comfort you’ll actually use from the automation you’ll pay for is the hard part, and a toto washlet comparison chart helps by lining up every current seat in one place. Wirecutter’s 2025 bidet seat guide picked the TOTO S5 as its top choice and highlighted how intuitive the remote is. That kind of endorsement speaks to one buyer in particular: the person upgrading a shared bathroom who has no interest in the most automated, priciest seats out there.
Product overview and current price position
The S5 is a bidet seat, not a whole toilet. It bolts onto a compatible bowl, and your existing fixture stays right where it is. QANSERO’s price list shows the full lineup: the S1 at $399, the S2 at $490, the KS6 at $599, the S5 at $682, the S7 at $1,279, and the S7A at $1,404. Those figures are advertised prices. Installation is extra. The S5 lands in the middle of that range, which happens to be where the value question gets interesting.
Electrical work is the line item people forget. No grounded outlet near the toilet? Budget for an electrician’s visit on top of the seat price.
What the TOTO WASHLET comparison chart actually gives you
The comparison page notes that some items were discontinued and replaced with newer modules. What sets the resource apart is its coverage of older products alongside the current lineup. Instead of a single isolated product description, you can put a current seat next to the discontinued model it replaced. The S2 and S5, for example, are identified there as successors to the retired C2 and C5 seats.

Shoppers who cannot decide also get a six-question recommendation prompt. Together, the model rows, replacement notes, prices and prompt keep the buying decision in one resource. Use the prompt, just know what it is: buying guidance, not independent performance testing.
S5 features at a glance
The comparison page lists the following for the S5. Each function covers a different piece of daily use or upkeep. None of them does away with routine manual cleaning.
| Disclosed feature | Practical use |
| Instant water heating | Warm wash water on demand, with no storage tank to refill and reheat. |
| Heated seat | Nice on cold mornings. |
| Warm-air dryer | Uses less paper, though you’ll wait a while for it to dry you. |
| Deodorizer | Handles odors while in use. |
| Night light | Lets you find the seat at night without lighting the whole room. |
| PREMIST | Rinses the bowl before use so waste is less likely to stick. |
| EWATER+ | Electrolyzed water for wand cleaning. |
A quick reality check on that table. These are listed capabilities, not measured performance scores. An included function is not the same thing as a fast or effective one, and that distinction matters most with the dryer and the cleaning aids, the two features buyers tend to overestimate.
Living with it every day
Picture two people sharing the bathroom before work. One likes a firm spray at a forward position; the other does not. Easy per-user adjustment solves that quietly, and it matters more in practice than any catalog description. What it does not tell you is how fast the dryer runs or how well the deodorizer handles your bathroom.
A shared seat still needs care. No control scheme removes mineral deposits or decides your cleaning routine for you.
Durability caution: Long-term care includes checking for mineral buildup around the wand or nozzles and following TOTO’s model-specific maintenance instructions.
Pros and cons

- Potential extra installation expense
- Less automation than premium options
- Comfort preferences that specs alone cannot settle before purchase
S5 versus S7A
The TOTO WASHLET S5 vs S7A decision is about convenience, not prestige. Bidets USA positions the S7A above the S5, and the automatic lid is the clearest dividing line between them.
| Buying consideration | S5 | S7A |
| Market position | Midrange luxury | Premium automation |
| Lid operation | Manual | Automatic |
| Best fit | Comfort-focused buyers | Automation-focused buyers |
What about the cheaper seats?
The S1 and S2 are worth a look if basic cleansing is the whole goal. The KS6 gives you a middle price point to weigh against the controls you actually want. Check the specific model rows rather than assuming the cheapest seat does what the S5 does.
Is the S5 worth the money?
Yes, if you want a more comfortable daily routine and are not paying primarily for hands-free operation. Automation is optional, not essential. Compare seat plus installation, never the sticker price alone. And if the electrical work comes back expensive, step back and price a simpler seat that fits the same bowl.
Frequently asked questions
Will a WASHLET fit an existing toilet?
Usually, but check first. Match the bowl shape, confirm water access and a grounded outlet, and verify mounting clearance.
What separates the S7 from the S7A?
The packages are close. The S7A adds automatic opening and closing; the S7 lid is manual.
Which WASHLET issues should buyers anticipate?
Fit checks and maintenance obligations, mostly. The comparison page documents included equipment, not failure rates, so do not read every installation hiccup as a defective unit.
Final verdict
Verdict: A strong attainable-luxury choice. For the buyer who wants attainable luxury through daily comfort rather than maximum automation, the S5 earns the recommendation on its published features alone. If hands-free convenience carries real personal value for you, the S7A is the better spend. Either way, verify toilet fit and electrical access before you order.
