Toto spares, Toto parts, Toto spare parts, Spare code no : DH2021 - Diverter Knob,

  • In Indian import / trade listings, “DH2021 DIVERTER KNOB TOTO SANITARYWARE & FITTINGS” appears under HSN code 74182020, imported into India from China.
  • This confirms “DH2021” is a recognized part name / SKU in trade / spare parts chains.

  • But these listings contain only shipment, quantity, and value data — no dimensional or spec details.
  • I found a TOTO diverter knob handle in another series: TOTO THP4250#CP — a knob handle unit for diverter, typically used with TOTO “Soiree” deck-mount bath faucet trims, made of brass with polished chrome finish.
  • This is not DH2021, but gives some insight into what a TOTO diverter knob product might be like (material brass, chrome finish).

  • That knob includes handle, setscrew, screw & washer accessories.
  • Because I found no product listing via product‑search for “DH2021 diverter knob,” it appears that DH2021 may be more of a spare parts / internal part number rather than a catalog consumer model.

Likely / expected characteristics (educated guesses)

Based on how diverter knobs are typically built, and how TOTO’s other diverter knob / handle units are constructed, one can expect:

AttributeLikely / Typical ValueMaterialBrass core / body, chrome plated finish (for durability and corrosion resistance)FinishPolished chrome (or equivalent decorative finish)Mounting / attachmentSet screw or internal screw fastening to stem / diverter shaftCompatibility / fitMust match the diverter’s stem dimensions (spline count, diameter, depth, etc.)UsageTo pull or rotate to divert water flow between outlets (e.g. bath / shower)

What to do to get exact details

To obtain the exact specifications (thread, spline, length, diameter, etc.) for DH2021, you can:

  1. Contact TOTO India / TOTO spare parts department, quoting “DH2021 diverter knob” and supplying your fixture model.

  2. Go to a local plumbing / sanitaryware spare parts dealer, especially one that stocks TOTO spares, and show them any existing knob or the diverter stem; they might cross‑reference to DH2021.

  3. Physically measure the existing knob / stem:
  • Diameter of the bore (inside)

  • Spline shape / number of splines (if it uses splines)

  • Depth / insertion length

  • External dimensions / decorative shape
  1. Search in TOTO spare parts catalogs / PDF manuals (if you can get hold of those internally) — sometimes there is a parts breakdown drawing with the DH‑series numbers.
