As part of our comprehensive plumbing services in Shreveport, we deliver professional results backed by decades of experience.

Why Bathroom Plumbing Matters

A typical Shreveport household uses its bathroom fixtures dozens of times each day. That constant cycling of valves, seals, and drain components leads to inevitable wear. A dripping faucet wastes thousands of gallons annually. A slow shower drain builds biofilm and odor. A failing shut-off valve turns a minor repair into a flooding emergency.

Shreveport’s municipal water carries mineral content that accelerates buildup inside faucet cartridges and aerators. Over time, calcium and lime deposits restrict flow, damage internal components, and shorten the lifespan of fixtures that should last a decade or more. Professional service addresses the root cause, not just the symptom.

Ignoring small bathroom plumbing issues also creates hidden moisture problems. Leaking supply connections behind walls feed mold growth that thrives in Northern Louisiana’s humidity. By the time you notice staining or smell musty air, the damage has already spread beyond the original leak point.

Our Bathroom Plumbing Services

Faucet Repair & Installation

We service all faucet types — single-handle, widespread, centerset, and wall-mount. Whether you need a cartridge replacement to stop a persistent drip or a full upgrade to a modern fixture, we handle the removal, installation, and supply line connections cleanly.

Sink & Vanity Plumbing

From pedestal sinks to double-vanity configurations, we manage drain assemblies, P-trap installations, supply hookups, and pop-up drain mechanisms. We ensure proper venting and slope to prevent standing water and odor issues.

Shower Valve Repair & Replacement

Shower valves control temperature mixing and water flow behind the wall. When yours sticks, leaks, or fails to maintain temperature, we access the valve body, diagnose the failure, and repair or replace it without unnecessary wall damage.

Tub Drain Service

Slow tub drains are one of the most common bathroom complaints. We clear obstructions, replace corroded drain assemblies, service overflow plates, and address trip-lever or push-button stopper mechanisms that have stopped sealing properly.

Toilet Connections & Supply Lines

Beyond toilet repair itself, we handle the supply connections, shut-off valve replacements, and wax ring seals that keep your toilet securely mounted and leak-free at the floor and wall connections.

Fixture Upgrades

Upgrading from builder-grade fixtures to premium hardware improves both function and appearance. We install rain showerheads, handheld sprayers, thermostatic mixing valves, touchless faucets, and other modern bathroom components.

Frequently Asked Questions

How do I know if my faucet needs repair or replacement?

If the faucet is less than 10 years old and the body is in good condition, a cartridge or valve replacement usually restores full function. If the fixture is corroded, outdated, or has had multiple repairs, replacement is more cost-effective long-term.

Can you install a faucet I purchased myself?

Yes. We install customer-supplied fixtures regularly. We recommend confirming the faucet matches your sink’s hole configuration before purchasing — we can advise on compatibility if you are unsure.

Why does my bathroom drain smell like sewage?

The most common cause is a dried-out P-trap, which allows sewer gas to rise through the drain opening. Running water for 30 seconds usually resolves it. If the odor persists, a venting issue or damaged drain line may be the source.

How long does a faucet installation take?

A straightforward faucet swap typically takes 45 minutes to an hour, including removing the old fixture, cleaning the mounting surface, and connecting the new unit. Older plumbing or corroded connections can add time.

Do Shreveport homes have hard water that affects fixtures?

Shreveport’s water is moderately hard, which accelerates mineral buildup in aerators, cartridges, and showerheads. Regular cleaning extends fixture life, and we can recommend filtration options if buildup is a recurring problem.

Can you fix a shower that only gets lukewarm water?

Yes. This typically indicates a failing mixing valve or a problem with the hot water supply line. We diagnose the cause and repair or replace the valve to restore proper temperature control.

What causes low water pressure in just the bathroom?

Common causes include clogged aerators, partially closed shut-off valves, corroded galvanized supply lines (common in older Shreveport homes), or a failing pressure-balancing valve in the shower.

Do you work on both upstairs and downstairs bathrooms?

We service bathrooms on any floor, including accessing supply lines and drains through walls, ceilings, and crawl spaces as needed. We take care to minimize any access openings required.

Is it worth upgrading to a low-flow showerhead?

Modern low-flow showerheads provide strong, satisfying pressure while reducing water consumption by 25 to 50 percent. With Shreveport water and sewer rates, the savings add up over a few years.

Can you add a shut-off valve where one does not exist?

Yes. Many older Shreveport homes lack individual fixture shut-off valves. We install quarter-turn ball valves on supply lines so you can isolate a single fixture without shutting off water to the entire house.
