TOTO THP4255#PB – Frequently Asked Questions
1) What does the TOTO THP4255 extension kit actually do?
It is a 3/4 inch extension kit for a TOTO valve, adding 3/4 inch of depth so the trim can sit correctly when the valve body is set deeper in the wall than normal (thick tile, stone, or a built-out wall). It is a trim depth accessory, not a valve or a trim set on its own.
2) My TOTO shower valve is buried too deep behind thick tile. Will a 3/4 inch extension kit fix it?
If the valve sits up to 3/4 inch too deep, yes, that is exactly what the THP4255 kit is for. If the shortfall is more than 3/4 inch, one kit will not get you there, and the correct fix is relocating the valve rather than stacking extensions.
3) Is an extension kit the same thing as a longer shower trim or a thick-wall kit?
No. An extension kit adds a fixed amount of depth, here 3/4 inch, to the existing valve and trim so the handle and escutcheon land flush. A thick-wall or rough-in replacement changes the valve body itself. Reach for the extension kit when the valve is already installed and only the depth is wrong; if the valve is the wrong model for the wall build-up, the extension will not correct that.
4) Do I need to open the wall to install the THP4255 extension kit?
No wall demolition is needed for the extension itself. The kit works from the finished face: pull the trim, add the 3/4 inch extension to the valve, then reinstall the trim. That is the point of an extension kit, it avoids moving the rough-in.
