Your bathroom sink is one of the most frequently used fixtures in your home. From brushing teeth to washing hands, it plays a vital role in your daily routine. So, when your bathroom sink starts acting up – whether it’s a persistent drip, a frustratingly slow drain, or water gathering under the cabinet – it’s more than just an annoyance. These seemingly minor issues can escalate quickly, leading to wasted water, potential water damage, mold growth, or even structural problems if left unaddressed.
At Shaw Plumbing, we understand the unique plumbing challenges homeowners face in Spokane, WA. We’re dedicated to providing prompt, professional, and lasting solutions for all your bathroom sink repair needs. Our licensed and experienced Spokane plumbers are equipped to diagnose and fix any issue, ensuring your bathroom sink returns to optimal function quickly and efficiently.

Common Bathroom Sink Problems We Fix in Spokane
- Leaky Bathroom Sink Faucets: A constant drip, drip, drip from your faucet isn’t just irritating; it can waste hundreds of gallons of water annually. We repair or replace worn-out washers, O-rings, cartridges, or corroded parts causing the leak, whether it’s at the spout, handles, or the faucet base.
- Clogged Bathroom Sink Drains: Hair, soap scum, toothpaste, and small foreign objects are common culprits behind a clogged bathroom sink. This leads to slow draining or standing water. We use specialized tools and techniques, including snaking and hydro-jetting, to clear stubborn blockages and restore proper flow.
- Low Water Pressure: If your bathroom sink isn’t delivering enough water pressure, it can be frustrating. This problem can stem from issues like mineral buildup in the faucet aerator, valve problems, or corrosion in your water supply lines. We’ll accurately diagnose the cause and restore your desired water flow.
- Leaking Drains & P-Traps: Water puddles in your under-sink cabinet are a clear sign of a leaky bathroom sink drain. This often points to issues with the P-trap (the U-shaped pipe), the drain assembly, or loose connections. We quickly identify and repair these leaks to prevent water damage and mold.
- Faulty Pop-Up Stoppers: If your sink stopper isn’t holding water or won’t open/close properly, it hinders your sink’s functionality. We can repair or replace broken sink stopper mechanisms to ensure smooth operation.
- Loose or Wobbling Sinks: Especially with pedestal or wall-mounted sinks, a wobbly fixture can be a safety concern and may lead to plumbing stresses. We can securely re-mount and stabilize your bathroom sink.
- Gurgling Drains: A gurgling sound after water drains can indicate a partial clog deeper in the drainpipe or a vent pipe issue within your bathroom sink plumbing system.
- Foul Odors from the Drain: Persistent bad smells often point to trapped debris, mold, or a problem with the drain’s P-trap, which should hold water to prevent sewer gases from entering your home.
- Water Coming Up the Drain: If water is backing up or “coming up” your bathroom sink drain, especially when other fixtures are used, it signals a significant blockage in the main drain line that needs immediate attention.
Moving Sink Plumbing in Bathroom: Expert Reconfiguration Services
Moving a bathroom sink? Sometimes, a simple repair or replacement isn’t enough. For homeowners in Spokane embarking on a bathroom renovation, a reconfigured layout, or upgrading to a custom vanity that requires a new sink location, you’ll need professional expertise in moving bathroom sink plumbing. This complex service involves more than just connecting a new fixture; it often requires altering existing water supply lines, rerouting drainpipes, and ensuring proper venting within your walls or floor.
At Shaw Plumbing, our licensed plumbers are experts in relocating bathroom sink plumbing to perfectly match your specifications. We understand the intricacies of plumbing alterations, ensuring all work meets Spokane building codes and provides optimal water pressure and drainage. Whether you’re shifting your sink a few inches, moving it to an entirely new wall, or converting a half-bath into a full bath, we handle the entire process with precision and care, minimizing disruption and ensuring your new bathroom layout is fully functional and leak-free.

DIY Bathroom Sink Repair vs. Professional Plumbing: When to Call an Expert
For minor issues like a loose aerator or a very superficial clog, some DIY attempts might seem appealing. However, when it comes to persistent problems with your bathroom sink plumbing, the risks of a DIY approach often outweigh the potential savings.
Call a professional Spokane plumber like Shaw Plumbing if you’re dealing with:
- Persistent Leaks: If tightening connections doesn’t stop a leak, or if water is appearing under the sink or in your cabinet, it’s time for professional leak detection and repair.
- Deep or Recurrent Clogs: If plungers or chemical drain cleaners aren’t effective for your clogged bathroom sink, you likely have a deeper blockage that requires professional equipment and expertise.
- Low or Fluctuating Water Pressure: Diagnosing the cause of low water pressure can be complex and often requires professional assessment of your entire bathroom sink plumbing system.
- Issues Requiring Disassembly: Any repair that involves disassembling faucet components, drain assemblies beyond basic tightening, or working with pipes should be handled by a professional to avoid costly errors.
- Concerns About Water Damage: If you suspect water has been leaking unnoticed, or if you see signs of water damage, a plumber can assess the extent and fix the underlying issue.
Attempting complex repairs without the proper tools, knowledge, and experience can aggravate the problem, lead to costly water damage, void warranties, and even pose safety hazards. Trust the experts at Shaw Plumbing to handle your bathroom sink repairs safely and effectively.

Frequently Asked Questions About Bathroom Sink Repair
What are the most common causes of a leaky bathroom sink faucet?
Most leaky bathroom sink faucets are caused by worn-out internal components like washers, O-rings, or cartridges. Over time, these parts degrade, leading to drips and leaks.
How do I know if my bathroom sink drain is seriously clogged?
Signs of a serious clog include extremely slow draining that doesn’t improve with plunging, standing water that won’t go down, or water backing up into the sink when other fixtures (like a toilet or shower) are used.
Can a loose bathroom sink cause water damage?
Yes. A loose or wobbly sink can strain the plumbing connections over time, leading to leaks from the supply lines or drain pipes, which can cause significant water damage to your vanity, floor, or ceiling below.
Do you repair all brands of bathroom sink faucets?
Yes, our experienced plumbers are familiar with and can repair or replace parts for most major brands of bathroom sink faucets and fixtures. We also handle the installation of any brand you choose.
What should I do if my bathroom sink overflows?
Immediately turn off the water supply to the sink (usually shut-off valves are located under the sink). Then, call a professional plumber right away to diagnose and repair the issue, as an overflow indicates a significant clog or a problem with the overflow drain itself.
