TOTO THP4533 – Frequently Asked Questions
1) What exactly comes with the TOTO THP4533 valve stem extension kit?
The TOTO THP4533 is supplied as a long screw and washer. It is a fastener set, not a complete valve or trim assembly, so you would reuse the existing valve and trim and just swap in the longer screw and its washer.
2) Is THP4533 the part number I give my plumbing supplier for the TOTO stem extension?
Yes. THP4533 is the TOTO manufacturer part number, and it is the only configuration offered for this stem extension screw and washer. Order it by that number and there are no finish or length options to specify.
3) Will the THP4533 long screw and washer fix a shower trim that sits too far off the finished wall?
That is the purpose of a stem extension fastener like this one. When tile or a thicker wall build-up leaves the valve set deeper than the trim allows, the longer screw and washer let the handle or trim reach and clamp to the stem. It is a TOTO plumbing part, so match it to the TOTO valve you are working on rather than to another brand's cartridge.
