Bathroom Plumbing in Mesa, AZ
Toilet, shower, and sink repair and installation
The bathroom sees the highest volume of water usage in your home, making it the most frequent site of plumbing failures. A constantly running toilet wastes thousands of gallons a month, a dripping shower valve accelerates hard water staining, and a poorly sealed tub drain can quietly destroy the subfloor.
Prestige Plumbing Company handles all aspects of bathroom plumbing, from fast, reliable repairs of existing fixtures to complete rough-in plumbing for major renovations. We repair and replace toilets, install high-end shower valves and multi-head systems, and ensure vanity sinks drain perfectly.
We understand that bathroom downtime is highly disruptive, so our trucks are stocked with universal rebuild kits for common valves (Moen, Delta, Kohler) and high-quality replacement fixtures to complete most repairs in a single visit.
Benefits Of Professional Bathroom Plumbing
- Fast repair of running, leaking, or weakly flushing toilets
- Expert rebuilding or replacement of failing shower valves
- Precision installation of new vanity sinks and faucets
- Code-compliant drain and vent rough-ins for bathroom remodels
- Identification and repair of hidden leaks behind tile walls
Shower Valve Replacement
When a shower valve fails and cannot be rebuilt with a new cartridge, replacing the entire brass body inside the wall is required. This used to mean destroying the custom tile work.
Whenever possible, we perform valve replacements by accessing the plumbing from the drywall on the opposite side of the wet wall (e.g., from a hallway or closet). This preserves your expensive shower enclosure and leaves only a simple drywall patch.
Common Problems We Solve
- Toilets that run constantly, leak at the base, or fail to flush properly
- Shower valves that drip, lack hot water, or are incredibly stiff to turn
- Slow draining bathroom sinks clogged with hair and soap scum
- Water stains appearing on the ceiling below a second-story bathroom
Signs You Need This Service
- The sound of water trickling in the toilet tank long after a flush

Bathroom Plumbing Frequently Asked Questions
Why does my toilet keep running?+
The most common culprit is a deteriorated rubber flapper in the tank that fails to seal, or a fill valve that doesn't shut off when the water reaches the correct level.
Can you fix a dripping shower head?+
Yes. The issue is rarely the shower head itself; it is the cartridge inside the control valve behind the handle failing to shut the water off completely. We can usually rebuild the valve with a new cartridge.
My bathroom sink drains very slowly. Should I use Drano?+
No. Chemical cleaners damage pipes and rarely remove the entire blockage (usually a mat of hair and soap). We manually clear the p-trap and cable the branch line for a permanent fix.
Do you install customer-supplied fixtures?+
Yes. If you have purchased a faucet or toilet, we are happy to install it for you. We just ask that you ensure all parts are in the box.
