TOTO Washlet S2 vs S5: What Is the Difference and Which One Should I Buy?
The TOTO Washlet S2 and S5 are two of TOTO's most popular bidet seats, and they sit right next to each other in the lineup, which is exactly why so many buyers get stuck choosing between them. They look similar, they clean the same way, and the price gap is modest, so the decision really comes down to a single feature rather than a long list.
Quick answer: The S2 and S5 clean identically and share the same EWATER+ and PREMIST hygiene, CLEAN RESIN, a heated seat, tankless warm water, a warm air dryer, an automatic deodorizer, and a nightlight. The one real difference is control: the S5 adds a wireless remote that saves settings for up to four users, while the S2 keeps all of its controls on a side arm panel at a lower price. Choose the S5 if you want a remote and saved profiles for the household, and the S2 to save money when an arm panel suits you fine.

What the S2 and S5 have in common
It is worth starting with how much these two seats share, because the list is nearly the entire spec sheet. Both bring TOTO's core hygiene pairing of EWATER+ and PREMIST, where EWATER+ uses electrolyzed water to clean the wand automatically after each use and PREMIST wets the bowl beforehand so waste is far less likely to stick, and both add CLEAN RESIN, which keeps the wand and seat easier to maintain over time. Both wash with adjustable warm water front and rear, with rear soft, oscillating, and pulsating options and full control over temperature, pressure, and wand position, and both use an instantaneous heater so the warm water never runs out mid wash.
Both also carry the everyday comforts that make a Washlet worth owning, including a heated seat, a warm air dryer, an automatic deodorizer that works without sprays or cartridges, a built-in nightlight, a seamless seat design that removes the gap where grime collects, a SoftClose lid that undocks for easy cleaning, and an energy saver mode. Both fit round and elongated toilets, both come in Cotton White with the elongated seat also available in Sedona Beige, and both are WASHLET+ (T40) compatible so the cords and hose can be hidden on a compatible toilet. In daily use, the cleansing experience is the same on either seat.
The real difference: the remote
The one thing that actually separates the S2 and S5 is how you control the seat. The S5 comes with a wireless remote, which most people mount on the wall within easy reach, and that remote stores memory presets so each person in the household can recall their own wash, temperature, and pressure settings with a single button, for up to four users. The S2 instead keeps all of its controls on an arm-mounted panel built into the side of the seat, with no separate remote and no saved profiles.
For most buyers this is the whole decision. If you like the idea of a remote and personalized settings for a family, the S5 is the one to choose. If you are happy reaching to a side panel and do not need saved profiles, the S2 does everything else the same, for less.
Price
The S2 is $499 and the S5 is $682, so about $183 separates them. That gap is essentially the cost of the wireless remote and the saved presets, since every other feature is shared. Promotions can change the price you pay, so check the live product pages for today's numbers.
Who should buy the TOTO Washlet S2
Choose the S2 if you want TOTO's full hygiene and comfort set at the lowest price in this Washlet range, you are comfortable using a side arm panel, and saved user presets are not important to you. It is an excellent first Washlet and a strong fit for guest bathrooms or single-user households.
Who should buy the TOTO Washlet S5
Choose the S5 if you want a wireless remote rather than a side panel, or you want each member of the household to save and recall their own settings. For a primary bathroom shared by a family, the remote and presets are worth the modest step up.
Installation requirements
Both seats install the same way and suit most standard bathrooms:
- Bowl shape: measure from the center of the mounting holes to the front of the bowl. About 16.5 inches is round and about 18.5 inches is elongated, and you order the seat to match. See our toilet seat fitment guide if you are unsure.
- Mounting: the mounting holes are the standard 5.5 inches apart, and you want at least 2 inches of flat clearance in front of the tank.
- Water: both connect to your existing cold water supply with the included T valve, which is a quick do-it-yourself connection.
- Power: both plug into a grounded 120V GFCI outlet rated for 15 amps, with a power cord of about 4 feet. If there is no outlet near the toilet, have a licensed electrician add one.
If you have a TOTO WASHLET+ (T40) toilet, either seat can connect with the cords and hose hidden for a seamless look.
Frequently asked questions
What is the main difference between the TOTO Washlet S2 and S5?
The S5 comes with a wireless remote that stores memory presets for up to four users, while the S2 keeps all of its controls on a side arm panel with no remote. Their cleaning, EWATER+ hygiene, PREMIST, heated seat, and warm air dryer are the same.
Does the TOTO Washlet S2 come with a remote control?
No. The S2 is operated from an arm-mounted control panel on the side of the seat. If you want a wall mounted wireless remote with saved settings for each user, that is the S5.
Do the S2 and S5 fit round and elongated toilets?
Yes. Both are available for round and elongated bowls in Cotton White, with the elongated version also offered in Sedona Beige. The mounting holes are the standard 5.5 inches apart.
Do the S2 and S5 use the same EWATER+ and PREMIST?
Yes. Both use EWATER+ electrolyzed water to clean the wand after each use, and both use PREMIST to wet the bowl before use so waste is less likely to stick.
Do I need an electrician to install the S2 or S5?
Both connect to your existing water supply with the included T valve and plug into a grounded 120V GFCI outlet rated for 15 amps. If there is no outlet near the toilet, a licensed electrician should add one. The water connection is a simple do-it-yourself job for most people.
The verdict
The S2 and S5 are the same seat where it counts most, sharing EWATER+, PREMIST, CLEAN RESIN, a heated seat, tankless warm water washing, a warm air dryer, and a nightlight, so neither is a compromise on hygiene or comfort. The S5 earns its modest premium with a wireless remote and memory presets for up to four users, which make it the better fit for a family bathroom where saved settings and a remote genuinely help. The S2 keeps the exact same cleaning at a lower price for anyone happy with a side panel, and it remains one of the easiest ways to add a quality Washlet to a home.
