TOTO THU9478 – Frequently Asked Questions
1) Will the TOTO THU9478 fit an S350E washlet, or is it only for the S300E?
THU9478 is a TOTO replacement part covering both the S300E and the S350E, so the same part number applies whichever of those two seats you have. Order it by the MPN THU9478 rather than by description, since TOTO's washlet service parts differ between seat generations and the part number is what pins it to the S300E/S350E platform.
2) Is TOTO THU9478 a genuine TOTO service part or an aftermarket equivalent?
THU9478 is a genuine TOTO service part, sold under TOTO's own part number for the S300E/S350E washlet. For a facilities or MRO buyer standardizing on TOTO seats, that matters: the THU-prefix numbers are TOTO's factory replacement components, so you are matching the original component rather than substituting a generic.
