TOTO THP4978#BN – Frequently Asked Questions
1) What is TOTO part THP4978#BN?
THP4978#BN is a TOTO replacement handle assembly for a widespread lavatory faucet, supplied in the brushed nickel finish (TOTO's #BN suffix). It is a service part, not a complete faucet, so you order it when the handle on an installed TOTO widespread needs replacing rather than the whole fitting.
2) I need to repair a leaking TOTO widespread faucet. Is this handle the right part?
A handle assembly fixes a loose, broken, or stripped handle, not a drip. THP4978#BN is the handle portion only, so if water is passing when the faucet is closed you need the cartridge or valve unit for that faucet model instead. Match the repair part to the faucet's TOTO model number before ordering either one.
3) Will TOTO THP4978#BN fit a centerset or single-hole faucet?
No. It is a widespread trim part, meaning a faucet with the spout and two separate handle bodies set in three holes. Centerset and single-hole TOTO faucets use different handle parts, so for those you need the service handle listed against that specific faucet model.
4) Does the TOTO THP4978 handle come in any finish other than brushed nickel?
Brushed nickel is the single finish offered under THP4978#BN. TOTO codes finish into the suffix of the part number, so a polished chrome or other finish version of the same handle carries a different suffix and is ordered as a separate part number. If the other trim in the bath is chrome, this brushed nickel handle will not match.
5) For a hotel or multi-family bath with TOTO widespread faucets, how many of these handles do I need per faucet?
A widespread lavatory faucet has two handles, hot and cold, so a full handle replacement on one faucet takes two. Property managers standardizing on brushed nickel across a floor should count two per fixture and confirm the existing faucet model takes the THP4978 handle before buying in quantity.
