Bathroom Remodeling in Arlington Heights, IL

Most bathroom remodeling contractors are general contractors or bath system installers. They focus on the visible elements — tile, vanities, fixtures — and treat the plumbing as an afterthought. This approach leads to problems down the road.

At Plumbers 911, we start with the plumbing infrastructure and build outward. Here's why that matters:

Drain Location & Sizing — Moving a shower, bathtub, or toilet means relocating drain lines. Improper drain sizing or slope leads to slow drains, backups, and code violations. We engineer drain relocations to meet Illinois Plumbing Code requirements before any tile goes down.

Water Supply Reconfiguration — Adding a double vanity, body spray shower, or freestanding tub often requires upsizing water supply lines from ½" to ¾" mains. We calculate fixture unit demand to ensure adequate pressure and flow.

Venting Requirements — Every drain fixture needs proper venting to prevent siphoning and sewer gas entry. When you reconfigure a bathroom layout, the venting must be redesigned. This is where many general contractors make costly mistakes.

Hidden Pipe Issues — When we open walls for a remodel, we frequently discover corroded galvanized pipes, lead solder joints on copper, polybutylene supply lines (common in 1980s Arlington Heights homes), or deteriorating cast iron drain stacks. Addressing these issues during a remodel saves thousands compared to fixing them after the walls are closed up.

We provide complete bathroom remodeling plumbing services for Arlington Heights homeowners, from small powder room updates to full master bathroom gut renovations:

Complete Rough-In Plumbing — New water supply lines, drain/waste/vent (DWV) piping, and fixture connections for any bathroom layout. We work with copper and PEX supply systems and PVC or cast iron drain systems.

Bathtub & Shower Installation — Alcove tubs, freestanding soaking tubs, walk-in showers with linear drains, multi-head shower systems, steam showers, and tub-to-shower conversions. We handle all supply, drain, and valve connections.

Toilet Installation & Relocation — Standard, comfort-height, wall-hung, and smart toilets. If you're moving the toilet location, we handle the floor flange relocation and drain tie-in.

Vanity & Sink Plumbing — Single and double vanity installations, vessel sinks, wall-mounted sinks, and undermount configurations. We install supply valves, pop-up drains, and P-traps to code.

Water Heater Upgrades — A bathroom remodel is the ideal time to evaluate your water heater. Adding a large soaking tub or multi-head shower may require upgrading to a larger tank or adding a tankless unit.

Radiant Floor Heating — Hydronic radiant floor heating systems integrated into your bathroom remodel for year-round comfort on tile floors.

Accessibility Upgrades — Walk-in tubs, curbless showers, grab bars, comfort-height toilets, and anti-scald valve installations for aging-in-place remodels.

Arlington Heights' housing stock spans decades, and every era brought different plumbing materials and practices. Here's what we commonly discover when we open walls for a bathroom remodel:

Galvanized Steel Pipes (Pre-1970s Homes) — Homes built before 1970 in Arlington Heights often have galvanized steel water supply lines. These pipes corrode from the inside out, restricting water flow and causing rusty water. A bathroom remodel is the perfect opportunity to replace them with modern copper or PEX.

Lead Solder on Copper Joints (Pre-1986 Homes) — Before 1986, lead-based solder was commonly used on copper pipe joints. While the pipes themselves are fine, the joints can leach lead into your water. We identify and replace these connections during remodels.

Polybutylene Supply Lines (1978–1995 Homes) — Many Arlington Heights homes built or repiped during this period used polybutylene (gray plastic) supply lines. These pipes are prone to sudden, catastrophic failure. If we find them during your remodel, we strongly recommend replacing them.

Cast Iron Drain Stacks — Older Arlington Heights homes often have cast iron main drain stacks. After 50+ years, these can develop internal corrosion, cracks, and belly sags. We camera-inspect drain stacks during remodels and recommend replacement when needed.

Inadequate Venting — Many older bathrooms were vented using methods that no longer meet code (such as S-traps instead of P-traps with proper venting). We bring all venting up to current Illinois Plumbing Code standards during a remodel.

Bathroom remodeling costs vary significantly based on scope, materials, and the condition of your existing plumbing. Here's a general framework for Arlington Heights:

Powder Room Update (supply/drain connections for new vanity and toilet) — Plumbing costs typically range from $800–$2,500 depending on whether fixtures stay in the same location.

Standard Bathroom Remodel (tub/shower, toilet, vanity with supply and drain work) — Plumbing portion typically ranges from $3,000–$7,000 depending on layout changes and pipe condition.

Master Bathroom Renovation (complete gut with layout changes, dual vanities, large shower, soaking tub) — Plumbing costs typically range from $6,000–$15,000+ depending on the complexity of pipe rerouting and fixture count.

Factors that increase plumbing costs:

• Moving drain locations (requires concrete cutting for slab-on-grade homes)
• Replacing galvanized or polybutylene supply lines
• Upsizing water supply mains for additional fixtures
• Adding radiant floor heating
• Relocating the water heater or upgrading to tankless

We provide detailed written estimates that break down every plumbing cost before work begins. No surprises.

The Village of Arlington Heights Building Department requires permits for bathroom remodeling work that involves:

• Moving or adding plumbing fixtures
• Altering drain, waste, or vent piping
• Modifying water supply lines
• Installing or relocating a water heater
• Electrical work (lighting, exhaust fans, heated floors)

Simple fixture replacements in the same location (swapping a toilet or faucet) typically don't require a permit. However, any work that alters the plumbing layout does.

We handle the entire permit process — application submission, scheduling inspections, and ensuring all work passes on the first inspection. Our plumbers are fully licensed in the State of Illinois and understand Cook County code requirements thoroughly.

Key code requirements for Arlington Heights bathroom remodels:

• All drain piping must maintain proper slope (¼" per foot minimum)
• Every fixture trap must be properly vented within code-specified distances
• Anti-scald valves (pressure-balancing or thermostatic) are required for showers
• GFCI protection is required for all bathroom electrical outlets
• Exhaust ventilation is required for bathrooms without operable windows
