Onehole 3in1 solution that saves space: provides cold, hot and filtered water from a single mounting hole to keep your sink area clean and uncluttered. Pure (filtered) water and tap water run through independent pipes and outlets to prevent crosscontamination. Flexible coverage with 360° rotating spout: the tap tubes rotate fully so you can direct the nozzle anywhere across the sink — ideal for single or double bowls and for filling large pots. Independent controls and reliable valves: two separate handles operate two outlets. The right handle controls cold and hot water; the left handle controls purified water. The mixer includes two ceramic valve cores for durable, precise operation. Easy connection and wide compatibility: standard 1/2' connection size and includes a 1/4' clean water supply line adapter, allowing connection to most domestic water systems. Complies with European standards and fits common installation sizes. Practical performance and convenience: consolidated installation reduces drilling and plumbing complexity; independent piping preserves water quality for drinking and cooking; the fullrotation spout improves reach and workflow. Key specifications Function: Cold, hot and filtered water delivery from one tap Installation: Single mounting hole Control: Double handles, double outlets Valve type: 2 ceramic valve cores Spout movement: 360° rotation Connections: Standard 1/2' (includes 1/4' adapter for clean water) Compliance: Meets European standards Use scenarios Small kitchens or islands where counter or sink space is limited: install with a single hole to supply all three water types without extra fixtures. Family kitchens where drinking water must remain isolated from tap water: use the left handle and dedicated outlet for filtered water while using the right handle for hot/cold washing and cooking tasks. Busy prep areas with large or double sinks: rotate the spout across the sink to fill pots, rinse produce, and switch quickly between purified water and tap water without moving containers. What it solves Reduces clutter and installation complexity by combining three water functions into one tap. Prevents mixing of filtered and regular water with independent piping and outlets. Improves usability and reach with a fully rotating spout and separate controls for each water source.
