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.

RIDGID Telescoping Basin Wrench — Best Basin Wrench
The spring-loaded pivoting jaw grabs faucet mounting nuts up in the dark behind the sink, and the telescoping shaft reaches them. This is the tool that makes faucet R&R possible.

Telescoping shaft · spring-loaded reversible jaw
- Reaches faucet mounting nuts up behind the sink
- Telescoping shaft handles deep cabinets
- Reversible jaw both tightens and loosens
- Awkward in tight cabinets until you get the feel
- Jaw can slip on smooth chrome nuts
- A single-purpose tool
Verdict: The tool that turns a faucet swap from impossible into 20 minutes.
Danco Adjustable Basin Wrench — Best Budget Basin Wrench
A plain stainless steel basin wrench that locks to four set lengths between 10 and 17 inches instead of telescoping. Spring-action jaws, all metal, and it reaches the same faucet mounting nuts the RIDGID does.

Stainless steel adjustable basin wrench · four set lengths, 10 to 17 in · spring-action jaws
- Jaws take nut sizes from 3/8 in. up to 1-1/4 in.
- Four set lengths from 10 in. to 17 in.
- Loosens the basin nuts that hold the faucet in place
- The shaft steps between four settings rather than telescoping
- No built-in work light, so a dark cabinet still needs a torch

Channellock Pliers — Best Adjustable
Every homeowner should own a good pair of tongue-and-groove pliers for slip nuts, traps, and supply fittings. Channellock’s are the standard for a reason.

Tongue-and-groove adjustable pliers
- Do far more than just faucet work
- Grip a wide range of sizes
- Practically indestructible
- Too bulky for tight behind-sink nuts
- Can mar a finish if you are not careful
- Not a true basin wrench
Verdict: The pick if you want one tool for plumbing and everything else.
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.
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.
For threaded galvanized or iron pipe neither of those is enough — that job wants a 14-inch pipe wrench, and the brands are compared in Milwaukee vs RIDGID pipe wrench.
The reason most people buy a basin wrench is a faucet swap they’re already committed to. If that’s you, our bathroom faucet picks will tell you what’s worth installing once the old one is out.
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.
For every nut that is not buried behind a basin, a pair of channel locks does the job — here is the size guide.
A basin wrench is also the tool for a wobbly faucet — see how to tighten a loose faucet base.
