Half the faucet jobs homeowners give up on fail for one reason: the wrong tool. The mounting nuts behind a faucet are unreachable with a normal wrench, and that’s exactly what a basin wrench is for. A small kit of the right wrenches turns “call a plumber” into a 20-minute Saturday job.

Pro Tips for Using a Basin Wrench

The jaw is directional — flip it depending on whether you’re loosening or tightening. Get the jaw fully around the nut before applying force, and use the cross-bar at the bottom for leverage. A headlamp and a towel to lie on make the whole job easier.

FAQ

Do I really need a basin wrench? For removing or installing a faucet, yes — the mounting nuts are otherwise unreachable.

What size? A telescoping basin wrench self-adjusts to most faucet nut sizes (about 3/8″ to 1-1/4″).

One tool or a kit? A basin wrench plus tongue-and-groove pliers covers the large majority of home plumbing jobs.

Bottom Line

Buy the RIDGID basin wrench and a pair of Channellocks — that two-tool combo handles nearly every faucet and drain job a homeowner will face.

FAQ

What is a basin wrench used for?

Reaching and turning the hard-to-access nuts that hold a faucet to the sink — a job nearly impossible with a normal wrench.

What size basin wrench do I need?

A standard adjustable basin wrench fits most faucet nuts (about 3/8″ to 1-1/4″). A telescoping handle helps in deep cabinets.

Is there an alternative to a basin wrench?

For tight spaces, not really — it’s the right tool. Faucet-installation tools exist but a basin wrench is the cheap, reliable standard.
