The remote lets each user save preferred cleansing settings for quick access. The cleansing stream has pulsating and oscillating options, and the S5 offers five temperature settings for both the heated seat and warm air dryer.
TOTO says PREMIST wets the bowl surface before each use to help prevent waste from sticking. EWATER+ automatically cleans the wand inside and out.
The combination suits households that value several adjustable features. If you mostly want a warm water wash, compare options in our best smart toilet seats guide.
What does the S5 offer for everyday use?
The S5 brings together cleansing, comfort and cleaning features in one elongated seat. Its remote, adjustable spray and warm air dryer may suit your routine after using the toilet.
The continuous warm water stream is designed to last as long as needed. You can choose rear or front cleansing and adjust the stream with pulsating or oscillating options.
The seat has five temperature settings and SoftClose. A nightlight provides a soft glow, while the air deodorizer uses filters to neutralize bathroom odors.
The remote's four memory settings may be useful if multiple people use the seat. For an overview of electronic models, read our plain explanation of TOTO WASHLETs.
Does the S5 fit your toilet?
The S5 is an elongated seat measuring 21 inches long by 15.06 inches wide. Measure your toilet before ordering, because seat shape and mounting placement affect fit.
Check whether the bowl is elongated and measure from the mounting holes toward the front edge. Compare the bowl width and mounting area with the S5's dimensions, and leave room for the lid to open.
A matching shape alone does not confirm compatibility. Review the toilet compatibility checklist and confirm any uncertain measurements before buying.
How do the S5 and S2 compare?
The S5 and S2 share warm water, PREMIST, EWATER+, a heated seat, a deodorizer and a warm air dryer. The clearest difference is control: the S5 uses a wireless remote and four memory settings, while the S2 has a side panel.
The S2 measures 21 inches long by 18.44 inches wide. Compare that width with your toilet bowl instead of assuming the S2 and S5 have the same fit.
The S2 has a heated seat with three temperature settings and a dryer with three temperature settings. Choose it if you prefer a control panel attached to the seat and don't need the S5's four user memories.

How does the S5 compare with the S7A and KS6?
The S5 is a remote-controlled elongated seat with four user memories, while the S7A adds an automatic open and close lid. The KS6 also has an illuminated remote and four user memories, and its remote can be handheld or wall mounted.
The S7A's EWATER+ cleans the wand and helps clean the toilet bowl upon departure. It is compatible with WASHLET+ toilets with a concealed connection, and TOTO says it is auto-flush compatible with a separately sold kit.
The KS6 has five spray settings for front and rear washing, including pulsating or oscillating options. It measures 20.81 inches long by 15.25 inches wide.
Choose by the feature that changes your daily routine: saved settings on the S5 or KS6, a side panel on the S2, or automatic lid movement on the S7A. The remote vs side panel guide explains the control choice.
What should you know about cleaning features?
PREMIST and EWATER+ serve different cleaning roles. PREMIST wets the bowl surface before use, while EWATER+ automatically cleans the S5's wand inside and out.
These features can support routine bathroom care, but they do not remove the need to clean the toilet and seat. Follow TOTO's care instructions and use products suitable for the seat's materials.
The S5's warm air dryer may help with clean-up after washing. Consider whether you'll use it before choosing this feature-rich seat.
What are the trade-offs?
The S5's main trade-offs are its elongated fit requirement and the need to check bathroom installation conditions. Its controls and comfort features also add more settings to consider than a basic seat provides.
Think about where you'll keep the remote and whether saved user settings are useful to your household.
Measure the toilet carefully and check the electrical setup before buying. If you want a different control style, compare the S2's side panel; if you want an automatic lid, consider the S7A.
Is the TOTO WASHLET S5 worth considering?
The S5 is worth considering if you want remote control, four user memories, a heated seat and a warm air dryer in one elongated bidet seat. Its cleansing and wand-care features make it a feature-rich option within the TOTO range.
Choose the S2 if you prefer a side panel, or the S7A if an automatic lid matters more. Start with TOTO WASHLET S2 vs S5 to compare the closest alternative, and check your toilet dimensions before deciding.
