Cost GuideUpdated June 19, 2026
Planning a bathroom remodel is exciting, but overlooking the plumbing details is a mistake that can cost time, money, and headaches in homes around Elk Grove Village. Older homes here often have original pipes or drains that won't support modern fixtures or layouts. Our team has seen what goes wrong when plumbing gets treated as an afterthought instead of a foundation for the whole project.
Why Elk Grove Village Bathrooms Need Special Plumbing Attention
This area has a mix of housing built from the 1960s all the way up to recent years. We see a lot of homes with original galvanized steel supply lines or cast iron and clay-tile drains. These materials corrode or clog over decades. If your remodel means moving fixtures or adding features, you'll probably need to upgrade some of this piping. On top of that, the moderately hard, Lake Michigan water can speed up pipe scaling, and those cold Chicago winters will test any plumbing exposed to outside walls or crawlspaces.
Upgrading Old Pipes and Drains
When you take out old floors and walls, you get a rare chance to inspect and replace worn-out water lines and drains. Supply lines made of galvanized steel are common in homes 40 years or older and may be at the end of their life. Cast iron or clay-tile drains can be packed with mineral build-up or have tree roots sneaking in from outside. Replacing these with modern PEX or copper supply lines, and PVC or ABS waste pipes, saves you from costly leaks later. Our pipe repair and repiping services can handle these upgrades so you're set for another several decades.
Don't Forget the Main Shutoff and Drain Slope
A main water shutoff that works and is accessible is essential before major plumbing work. Some older homes in the northwest suburbs still have hidden or stuck valves. The new codes also require drains to have the right slope, typically a quarter inch per foot for horizontal pipe runs, to avoid standing water and clogs. Bathroom remodels are the perfect time to correct old, flat or back-pitched drains that cause slow drains or sewer smells. If you've had recurring issues, professional drain cleaning and, if needed, sewer line work can be part of the remodel package.
Fixture Planning Sizing, Placement, and Venting
Moving a toilet or shower isn't as straightforward as moving furniture. Code requires specific distances for vent pipes to prevent sewer gases from entering the house. Vents might need to be rerouted if you're changing the layout. Oversizing or undersizing supply lines can cause pressure problems. For example, adding double sinks or a body jet shower without upsizing the water piping usually means weak flow. All new faucets, tubs, and shower valves should be matched with the right supply and waste connections. Our faucet and fixture installation team knows what fits local homes and meets code.
What Impacts Cost in Elk Grove Village Bath Remodel Plumbing
- Pipe Material: Swapping to copper or PEX raises upfront cost but saves money in the long run compared to keeping tired galvanized lines.
- Fixture Location Changes: Moving a tub or toilet more than a couple feet means adjusting drains and vents, which is labor-intensive.
- Drain Line Condition: Old cast iron or clay pipes under the slab are expensive to move or replace if they're cracked or full of roots.
- Shutoff and Water Pressure: In homes with low pressure or sticky valves, expect an extra line item for new valves or even a pressure reducing valve.
- Unexpected Leaks: Opening walls can reveal hidden leaks or corrosion, so we always plan time for leak detection and repair during remodels.
Checklist Before You Start Your Remodel
- Have your main water shutoff tested and replaced if needed.
- Check the age and type of all visible water supply lines and drains. Plan to replace galvanized, old copper with green corrosion, cast iron, or clay-tile lines.
- Review the placement of all fixtures, especially if you want to move them further from original spots.
- Inspect vent piping and plan for any needed rerouting.
- Schedule a water heater checkup, adding spa tubs or big showers can overwork an old tank. See our water heater services for upgrades.
- Consider drain cleaning or camera inspection before closing walls and floors again.
If your home is in a lower spot or has a history of water in the basement, it's smart to check your sump pit and pump setup before major plumbing changes. You want to avoid any surprises with water backing up, especially in our flat, clay-soil yards. Our team can handle both sump pump work and full remodel plumbing so everything is protected during and after construction.
