Three tools do nine tenths of bathroom work

The best plumbing hand tools for 2026

Fitting a tap needs fewer tools than the aisle suggests. A basin wrench reaches the back nut you cannot see or get a hand to, and there is no substitute for it; water pump pliers with a push-button adjustment cover most nuts from a trap to a shower hose; and a pipe wrench handles the round threaded fittings that flat jaws slip on. Judge them on jaw capacity against what you will actually turn — a 32 mm trap nut, a 1/2 inch valve — and on length, because leverage is what turns a seized fitting and length is what does not fit under a vanity unit. One detail decides whether the job looks right afterwards: serrated jaws mark chrome, permanently. Smooth-jaw versions and plastic inserts exist for visible fittings, and a strip of cloth does the same job at zero cost. We compare jaw capacity, overall length, adjustment mechanism, jaw type and marking risk, and steel and finish.

    Overall length
    127 mm — stated
    Adjustment
    Push-button — press to set the opening, stated

    EAN
    0820909611165
    • Publishes a 25 mm jaw capacity, which is the figure this family should always give
    • At 127 mm it fits inside a vanity cabinet, where a 250 mm pliers cannot be turned
    • 25 mm will not take a tap back nut or a trap connector — those need the larger pliers in this hub

    Best for: Small work in confined space — an aerator, a compression nut, a valve spindle inside a cupboard.

    EAN
    4262495460240
    • A 52 mm jaw, which takes a basin tap back nut and a trap connector — the two things a bathroom job needs
    • A ratchet adjustment that holds its setting rather than needing constant re-seating
    • Toothed jaws mark a chromed fitting — wrap it in cloth or tape before gripping anything visible

    Best for: The actual bathroom jobs — a tap back nut, a trap connector, a seized angle valve — where 25 mm is not enough.
