Whether you are installing a kitchen faucet, replacing a bathroom vanity tap, or working around a pedestal sink, one of these wrenches is the right tool for the job.

The 5 Best Basin Wrenches Reviewed

1. RIDGID 57003 EZ Change Plumbing Wrench

The RIDGID 57003 EZ Change is a widely used basin wrench and our top pick. Unlike traditional basin wrenches with a single pivoting jaw, the EZ Change is a multi-functional faucet installation tool designed to work on supply lines, angle stops, basket strainers, and mounting nuts — making it the one tool that handles nearly everything under the sink.

The tool uses a 6-sided cubed insert that fits 5/8, 3/4, 7/8, 15/16, and 1 inch nuts, covering the full range of faucet mounting nuts found in standard American kitchens and bathrooms. The reinforced plastic body with aluminum inserts keeps the weight down to just one pound, so working overhead in tight under-sink spaces is far less tiring than with a heavy metal wrench.

This is one of the most widely used tools in our lineup. For a homeowner who wants a single versatile tool for faucet installation and supply line connections, the RIDGID EZ Change is the easy first choice.

Basin Wrench Buying Guide

What Is a Basin Wrench and When Do You Need One?

A basin wrench is a specialized plumbing tool designed to tighten or loosen the mounting nuts that secure a faucet to a sink. These nuts sit in a very tight space directly above the sink basin — between the underside of the sink deck and the back wall of the cabinet — where a standard wrench or adjustable pliers simply cannot fit. The basin wrench’s long handle and pivoting jaw are specifically engineered to reach into this confined space and apply controlled torque to nuts you cannot otherwise access.

You need a basin wrench any time you are installing a new faucet, replacing an existing faucet, or removing a faucet for repair. You also need one if you are removing corroded or stuck mounting nuts that have seized onto the faucet body after years of service.

Fixed vs Telescoping — Which Do You Choose?

A fixed basin wrench has a set handle length — typically 10 to 11 inches. This is adequate for most standard kitchen and bathroom sink installations where the mounting nuts are within easy reach above the drain. A telescoping basin wrench, like the Klein Tools 68232, extends from 10 to 17 inches to reach nuts in deep sink basins, farmhouse sinks, and pedestal sinks where a fixed wrench falls short. If you work on a variety of sink types, a telescoping model is worth the modest additional cost.

Jaw Capacity — What Size Do You Need?

Most household faucet mounting nuts fall between 3/8 inch and 1-1/4 inch. All five wrenches in our lineup cover this range, so jaw capacity is rarely a deciding factor for standard home plumbing. Where capacity matters is if you work on commercial or industrial fixtures with larger nut sizes — for those jobs always verify the jaw capacity specification before purchasing.

Traditional vs Multi-Function Wrenches

A traditional basin wrench — like the RIDGID 31175 — is designed purely for faucet mounting nuts. It does one thing and does it very well. A multi-function wrench, like the RIDGID EZ Change, handles mounting nuts plus supply lines, angle stops, and basket strainers in one tool. A specialist multi-function model like the RIDGID 27023 is optimized for angle stops and compression fittings rather than faucet nuts. Choose based on the full scope of your project, not just the first task on your list.

When to Use a Basin Wrench vs a Pipe Wrench

A basin wrench is for faucet mounting nuts and under-sink connections in tight, confined spaces. A pipe wrench is for threaded pipes, galvanized fittings, and large diameter connections where you need heavy torque on round objects. If your project involves both — for example replacing a faucet and also dealing with old galvanized supply lines — you will need both tools. See our guide to the best pipe wrenches for heavy pipe work, and our guide on how to fix a leaking pipe for a full walkthrough of the repair process.

Frequently Asked Questions

What is a basin wrench used for?

A basin wrench is a specialized plumbing tool designed to tighten or loosen the mounting nuts that hold a faucet to a sink. These nuts are located in a tight space directly behind and above the sink basin where a regular wrench cannot reach. The long handle and pivoting jaw allow you to work in this confined space easily.

Do I need a basin wrench to install a faucet?

For most faucet installations yes — the mounting nuts are located in a very tight space behind the sink that is impossible to reach with a standard wrench. A basin wrench makes the job straightforward. Some homeowners attempt it with slip-joint pliers but a proper basin wrench saves significant time and frustration.

What size basin wrench do I need?

Most household faucet mounting nuts fall between 3/8 inch and 1-1/4 inch, which any wrench in our lineup handles. For deeper sinks or pedestal sinks, choose a telescoping model like the Klein Tools 68232 that extends from 10 to 17 inches for extra reach.

Can I use a basin wrench on a kitchen faucet and bathroom faucet?

Yes — a basin wrench works on both kitchen and bathroom faucets. The jaw size and handle length are the same for both applications. The RIDGID 57003 EZ Change is particularly versatile as it also handles supply line connections and angle stops under both kitchen and bathroom sinks.

Final Verdict

For most homeowners, the RIDGID 57003 EZ Change is the clear best overall choice — well reviewed, widely used, and it handles supply lines, angle stops, and mounting nuts in a single lightweight tool. It is the most versatile basin wrench here for good reason.

If you prefer a traditional fold-over design with American manufacturing behind it, the RIDGID 31175 Model 1017 is the premium pick — Made in the USA with a Lifetime Warranty and strong reviews. For deeper sinks where reach is a problem, the Klein Tools 68232 telescoping wrench is a well-regarded professional option, with 10—17 inch adjustable reach. On a tight budget, the ARES 33004 gets the job done for a straightforward one-off faucet replacement. And if your project involves angle stop valves and compression fittings alongside the faucet work, add the RIDGID 27023 Model 2002 to your toolkit — well reviewed and built to the same standard.
