VOLA KV1 One-Handle Mixer

What it is

KV1 is VOLA’s deck-mounted one-handle mixer with ceramic-disc technology, a double-swivel spout, and a water-saving aerator — designed by Arne Jacobsen (brand date 1971; historic tearsheets also label early drawings 1972). It sits in the same modular VOLA family as the wall-mounted 111 and deck HV1, rooted in Jacobsen’s late-1960s collaboration with founder Verner Overgaard for Denmark’s National Bank (opened 1971). Brand thesis: hide the mechanics, leave cylinder, lever, and spout as pure geometry. VOLA states KV1 has been in MoMA’s permanent design collection since 1974.

Official catalog sheet: overall height 235 mm (~9¼ in), pipe 3/8”, deck hole 32 mm. US-market flow (fitting data at 3 bar / 43.5 psi): KV1US ~1.2 gpm (4.5 l/min); non-US KV1 sheets commonly cite a higher unrestricted figure — confirm the US aerator SKU on the quote. Family variants include KV1M (medium lever), KV1L (long lever), and longer-projection KV1/250 and KV1/300. Made to order at VOLA’s factory in Horsens, Denmark; brand: brass and stainless, modular parts still available for products dating back more than 50 years.

US authorized-dealer street (tracked examples, subject to change): PlumbTile lists chrome KV1 around $2,530 regular / ~$1,897 promo; Focal Point lists a KV1M config around $2,770 / ~$2,077 promo. Finish and lever change the number — confirm live quote with an authorized VOLA partner (showrooms such as KONST Union, Alexander Marchant, and other regional specialists; not a big-box SKU).

Who it’s for

Homeowners, architects, and kitchen/bath designers who want the Danish-minimal single-lever default — circle and cylinder, quiet authorship — especially when the rest of the scheme already speaks Scandinavian modern or Jacobsen grammar. Strong as a kitchen or lav deck mixer when pull-down spray modes are not the brief, and when matching VOLA wall-mounts or accessories elsewhere in the house matters.

Skip it if the sink needs an integrated pull-down or side spray, if you want traditional cross-handles (see our Dornbracht TARA), if US 1.2 gpm feels too lean for heavy pot-filling, or if made-to-order lead time and ~$2k+ chrome money are a non-starter. Also skip lookalike “minimal cylinder” imports — VOLA is the Jacobsen lineage and the parts ecosystem.

Standout details

• Specs that matter (brand / US dealers): 235 mm H · 32 mm deck hole · 3/8” supplies · ceramic disc · double-swivel spout · KV1US ~1.2 gpm · lever options standard / M / L · optional 250 / 300 mm projections
• Craft signal: made to order in Horsens; hand-painted colour finishes; high-grade brass and stainless; modular system shared with 111 / HV1 proportions
• Finish breadth: brand standard range includes four metallics (incl. polished chrome, brushed chrome, natural brass, stainless) plus 15 hand-painted colours; exclusive metallic/colour series exist — confirm current matrix with VOLA or the dealer
• Pedigree: Jacobsen / Overgaard National Bank lineage; KV1 named for MoMA permanent collection since 1974 (brand); continuous modular parts philosophy (“repairable and updatable… for life” on vola.com)
• Tradeoffs: no pull-down on this SKU; US flow is deliberately water-saving; natural brass will patinate if left unpolished (brand note); lead times are made-to-order, not shelf stock; street price sits above many premium single-hole mixers before you add exotic finishes

Who’s specifying

Architects and interior designers specifying Scandinavian-modern kitchens and baths; VOLA showrooms and authorized US partners (regional specialists rather than mass retail). Cultural context from brand and design press — not invented celebrity kitchens: VOLA and arnejacobsen.com place the series in the National Bank of Denmark total-design story; brand and secondary design coverage (Dezeen’s 50th-anniversary note on the Jacobsen/VOLA collaboration; IndesignLive on KV1) repeat the MoMA 1974 claim. Architectural Digest has credited “Sink fittings by Vola” in published residential work (e.g. a West Marin / Scandinavian-summer-home project) — treat that as brand presence in serious interiors, not a named KV1 SKU credit unless the caption says so.

Honest verdict

Catalog gap fill: we already cover Waterworks traditional lavs and Dornbracht’s cross-handle TARA kitchen mixer — no Danish-minimal fixture. KV1 is the fixtures-lane answer for that brief: House Score 4, not a blanket 5, because overall “primary option” depends on whether the house wants Jacobsen cylinders or another fittings language — design and durability carry it; value is the honest drag at US street. Draft until Press hosts official VOLA photography and greenlights. Start with polished chrome or brushed stainless if you want the quiet MoMA read; colour only when the scheme needs it on purpose.
