For the TOTO WASHLET S2 vs S5, choose the S2 if you want controls attached to the seat, or the S5 if you want a wireless remote and saved preferences. Both offer instant warm water, PREMIST, EWATER+ wand cleaning, a heated seat, deodorizer and warm air dryer.

The main decision is how you want to control the seat. The S2 keeps its panel beside you, while the S5 lets you use a remote and save up to 4 user settings.

The S5 also has more temperature steps for its seat and dryer. The S2 gives you specified water pressure and temperature settings, so its adjustment range may suit you if those controls matter most.

TOTO WASHLET S2 vs S5: which features change your choice?

The S5 suits buyers who want a remote, saved preferences and more seat or dryer temperature settings; the S2 suits buyers who prefer a side panel. Both share the main cleansing and self-cleaning features, so you do not need to choose based on those alone.

Each seat provides an instant, continuous warm water stream. Both offer front and rear cleansing, with pulsating and oscillating options described for the stream.

PREMIST mists the bowl before use, and EWATER+ automatically cleans the wand inside and out. These features are common to both models, as are the heated seat, air deodorizer and warm air dryer.

That shared feature set makes the control layout and adjustment details more useful than a long feature checklist. Think about who will use the seat, where they want controls and whether saved preferences will make a difference.

Which TOTO WASHLET S2 vs S5 controls fit your routine?

Choose the S2 for a fixed side panel and the S5 for a wireless remote. The right layout is the one you and other users can reach and operate without searching for controls.

The S2's panel stays attached to the seat, so you don't need to keep a separate remote nearby. Its controls let you personalize water cleansing settings.

The S5's wireless remote provides personalized cleansing settings and 4 user memory slots. In a shared bathroom, saved settings can make it quicker for different people to return to their preferences.

A remote can be misplaced or left somewhere inconvenient. If that is likely in your household, the attached S2 panel may be the simpler choice.

If you value having controls in a separate location, the S5 is the better match.

The TOTO WASHLET S5 review covers that model in more detail. For a plain-language overview of the range, see what a TOTO WASHLET is.

Do the S2 and S5 offer different wash settings?

Both seats offer instant warm water and cleansing options; the S2 has specified water temperature and pressure steps. The S5 lists more settings for seat and dryer temperature, while its water setting counts are not specified.

The S2 provides 3 water temperature settings and 5 pressure settings. It also has 3 seat temperature settings and 3 warm air dryer temperature settings.

The S5 provides 5 temperature settings for its heated seat and warm air dryer. It has instantaneous water heating and adjustable water cleansing, but the number of water temperature and pressure steps is not specified.

Choose the S2 if knowing the stated pressure range is important to you. Choose the S5 if you expect to adjust seat or dryer warmth often and want more temperature steps there.

More steps do not automatically make a seat easier to use. A simple routine may need only one comfortable setting, while a household with several users may value the S5's memory more than fine adjustments.

What cleaning and comfort features do both seats share?

The S2 and S5 both combine warm water cleansing with PREMIST and EWATER+ wand cleaning. Their shared features make the control layout and seat settings the more useful points of comparison.

PREMIST uses incoming water to mist the bowl before each use, which is intended to help prevent waste from sticking. EWATER+ automatically cleans the wand inside and out.

Both seats include a heated SoftClose seat, an air deodorizer and a warm air dryer. These features can make sense if you want more than a water spray, but they add functions you may not need if a basic bidet seat is your goal.

The two models also have pulsating and oscillating stream options. If those options matter to your routine, both cover them, so focus on whether you'd rather use an attached panel or remote.

For a broader explanation of the category, our guide to TOTO WASHLET vs a regular bidet seat explains how an electronic WASHLET differs from a simpler seat.

Will the S2 or S5 fit your toilet?

Both models are elongated, but measure your bowl and the space around it before buying. The S2 is wider than the S5, so width and nearby clearance deserve a careful check.

Each seat measures 21 in long. The S2 measures 18.44 in wide, while the S5 measures 15.06 in wide.

Don't assume that an elongated label guarantees a fit on every toilet. Compare your bowl shape and mounting area with the seat dimensions, and consider nearby walls or fixtures that could affect access to the controls.

The S2 weighs 13.5 lb and the S5 weighs 15.4 lb. Each is described as easy to install, but the toilet's shape and the installation instructions still guide the actual setup.

Before ordering, check that the toilet has the right shape and that the mounting area gives the seat room to sit correctly. Our bidet seat compatibility checklist walks through the measurements to take.

How should you set up and care for a WASHLET?

Start by checking toilet compatibility, the installation instructions and access to the required water and electrical connections. A careful setup makes the controls easier to reach and gives the seat a stable fit.

Lay out the parts and read the instructions for your exact model before removing the existing seat. Confirm the toilet shape and mounting points, then follow the maker's steps to attach the seat and connect it.

After installation, try the controls while seated and choose comfortable water, seat and dryer settings. If you're installing the S5, decide where the remote will stay between uses and show other users how to select or recall their saved preferences.

For either model, use the automatic EWATER+ wand cleaning as designed and follow the seat's care instructions for cleaning its surfaces. Avoid assuming that a self-cleaning wand means every seat surface or the toilet bowl needs no routine cleaning.

A common setup mistake is ordering based on the word “elongated” alone. Measure first, especially if the seat area is narrow or a wall or fixture is close to one side.

Another mistake is choosing the S5 for its remote without deciding where the remote will live. Pick a regular place for it so users can find it, or choose the S2 if attached controls sound more practical.

Who should choose the S2?

The S2 is the better fit for buyers who want a side panel, specified water pressure steps and the core warm-water features. It gives you the shared essentials without requiring a separate remote.

Choose it if you prefer controls to stay on the seat or want 5 stated pressure settings and 3 water temperature settings. It can also suit a household where remote storage would become one more thing to manage.

Skip the S2 if multiple users need separate saved settings or you specifically want more seat and dryer temperature steps. Its user memory count is not specified, and it offers 3 seat and dryer temperature settings.

The S2 is not the right choice just because it costs less or is simpler; no price comparison is included here. Choose it when its control layout and adjustment details fit the way you expect to use the seat.

Who should choose the S5?

The S5 is the better choice for buyers who want a wireless remote, 4 saved user settings and more seat or dryer temperature steps. Those features can be useful when several people share the bathroom or prefer different preferences.

Choose it if you value saving personal settings instead of readjusting controls each time. It also suits someone who wants a remote they can position separately from the seat.

Skip the S5 if you prefer a permanent control panel or are likely to misplace a remote. If stated water pressure and temperature step counts are central to your decision, the S2 gives those counts, while the S5 does not specify them.

The S5 review is useful if the S5 is your likely pick. Read it alongside the comparison chart if you want to compare additional WASHLET models.

Should you also consider the TOTO C5?

The C5 is a useful alternative if you want a remote and 2 user memory settings, but instantaneous water heating is not specified for it. It shares PREMIST and EWATER+ with the S2 and S5, along with a heated seat, deodorizer and warm air dryer.

The C5's remote includes 2 user memory settings. Its seat and dryer each have 5 temperature settings, and its listed dimensions are 20.88 in long by 15.06 in wide.

Consider it if you are comparing TOTO seats beyond the S series and the remote layout appeals to you. If instantaneous water heating is a must-have, the S2 and S5 are the clearer choices based on their stated features.

Which TOTO WASHLET should you choose?

Choose the S2 for attached side controls and specified water pressure settings; choose the S5 for a remote, 4 saved preferences and more seat or dryer temperature steps. Check the toilet dimensions first, then decide which control setup fits your household.

If one fixed panel sounds easiest to manage, pick the S2. If several people want quick access to personal settings, or you prefer a remote, pick the S5.

Both provide instant warm water, PREMIST, EWATER+ wand cleaning, a heated seat, deodorizer and dryer. For a wider set of options, browse our guide to the best bidet toilet seats, then compare the S2 and S5 on controls and fit.
