Complete Bathroom Plumbing Services
Your bathroom's supply lines, drains, and fixtures all work together — when one fails, the rest often follow. Pioneer Plumbing repairs and installs toilets, shower valves, tub plumbing, and sinks and faucets, whether it's a single fix or a full remodel.
Toilet Repair & Replacement
A toilet that runs constantly, flushes weakly, or rocks at the base usually points to a worn flapper, fill valve, or wax ring. We repair what can be fixed and replace toilets that have reached the end of their life, resealing the base to prevent future leaks.
Shower Valve & Shower Head Repair
Inconsistent water temperature or a leaking valve is often a sign of a worn cartridge or mineral buildup — and can mean hidden damage behind the wall. We repair and replace single-handle, dual-handle, and thermostatic valves, plus shower heads of every style.
Tub & Shower Plumbing Services
A slow drain, stuck diverter, or water pooling at the base signals a problem with the plumbing behind your tub or shower. If a clogged drain won't clear on its own, we fix it directly or handle full plumbing connections when a tub or shower is replaced.
Bathroom Sink & Faucet Service
Loose connections and worn parts are the usual causes of sink and faucet leaks — and left alone, they can damage your vanity and flooring. We install and repair pedestal, vanity, and vessel sinks, along with faucets in any style or finish.
Bathroom Plumbing for Remodeling Projects
A bathroom remodel is the easiest time to fix aging plumbing before it becomes a problem. We work with homeowners and contractors to relocate lines, add fixtures, and get the plumbing right from the start.
Signs You May Need Bathroom Plumbing Repair
- Toilet runs constantly or needs multiple flushes
