Bathroom layouts in Bolingbrook homes, especially those built in the 1970s and 1980s, often feature a standard tub that just doesn't work for every family. Many local homeowners look to upgrade to a walk-in shower, whether for safety, style, or plain convenience. We handle these conversions on a regular basis, and there are a few key plumbing realities you should factor in before starting the job.
Why Bolingbrook Homes Need Professional Tub-to-Shower Conversions
Older houses in the area usually have supply lines and drains sized for a tub. Changing to a walk-in shower means reworking these lines to fit the new configuration, which includes adjusting the height and location of drains and making sure the water supply can handle different fixtures. Many homes here still have galvanized or even cast iron pipes. These can be corroded or partially clogged after decades of use, so we often recommend inspecting them and, if needed, taking care of pipe repair or repiping at the same time as your remodel.
Steps Involved in Converting a Tub to a Walk-In Shower
Turning a tub space into a shower isn't as easy as swapping out fixtures. Here are the main steps our crew follows:
- Shut off water supply at the main valve and safely remove existing fixtures, including old water lines and the waste overflow.
- Assess the subfloor and wall cavity for leaks, rot, or mold that may have gone unnoticed behind the old tub.
- Inspect and upgrade old supply or drain lines, especially if the home has galvanized or cast iron piping.
- Relocate and size the drain to match the new shower pan, this usually means shifting from a tub's 1-1/2" drain to a standard 2" shower drain.
- Install new shutoff valves and run the water lines to suit the chosen shower valve and head configuration.
- Set the shower pan or build a custom base, then waterproof all seams and install backer board before tile or wall panels go up.
- Connect new fixtures, test for leaks, and finish with caulk and trim.
Every step needs to be watertight, flat, and up to code. We see frequent issues in DIY jobs where improper slope leads to slow draining or leaking at seams, which can cause headaches down the line. When in doubt, it pays to get a professional assessment early.
Plumbing Considerations Unique to Bolingbrook
Bolingbrook's clay soil and high water table make basement and crawlspace work tricky, especially if your bathroom sits above ground level or if the home's foundation has settled. We also deal with moderate water hardness from the municipal supply, which slowly builds up mineral deposits inside valves and around new fixtures. If you're adding multiple shower heads, body sprays, or want a rain shower, it's smart to check your water heater's capacity as well. Sometimes, a water heater upgrade is the best way to keep hot water flowing strong.
If your remodel is part of a larger overhaul, now is the logical time to consider upgrading faucets and fixtures throughout the bathroom for both looks and efficiency.
Warning Signs of Plumbing Issues Before You Convert
Before you start demo, watch for these signs that your plumbing needs attention during the remodel:
- Slow draining or gurgling from the tub or nearby sinks
- Visible corrosion or discoloration on supply lines under the tub
- Stains or moisture on walls and floors near the bathroom, which may point to hidden leaks
- Loud banging or whistling when faucets are used (can indicate aging pipes or worn shutoff valves)
- Water that looks brownish when you first turn on the tap, often from rust inside old galvanized pipes
Any of these issues should be checked before tile and glass go in. Our crew can pinpoint leaks with leak detection tools, or handle a drain cleaning if roots or debris have found their way into the line.
Getting a Safe, Accessible New Shower
Safety matters, especially if you're looking to make your Bolingbrook bathroom easier for someone with mobility concerns. We always check that new shower controls are within easy reach and that non-slip floors are part of the plan. If you have older pipes, installing pressure-balancing valves can prevent sudden swings in temperature if someone flushes a toilet or runs a sink elsewhere. Our team can also add grab bars and a low or zero-threshold base to take the worry out of getting in and out of the shower.
The right planning keeps your new shower safe, code-compliant, and trouble-free for years. Every detail matters, from the slope of the shower pan to the placement of the drain in clay soil, which can be a challenge during wet seasons common in the Chicago area.
Long-Term Value and What to Plan For
Turning a tub into a walk-in shower makes daily use easier and can add long-term value, especially in a market with a mix of older and newer properties. It's smart to have a pro check the main water shutoff and the condition of your supply lines before finalizing your plans. For complex jobs and older homes, we coordinate with our remodeling team to make sure plumbing, waterproofing, and finishes work together. If you have basement plumbing, it's also worth checking your sump pump and drainage, since water issues under the bathroom can undo your hard work upstairs.
