Buyers GuideUpdated June 28, 2026
Old tubs aren't always practical for how families use bathrooms today. In Barrington, a lot of homes have layouts or plumbing that date back decades. Replacing a bathtub with a walk-in shower often makes the most sense for homeowners who want better access, less hassle with cleaning, or a more modern look. If you're thinking about this change, it pays to know what's involved and which hidden issues tend to pop up, especially in homes built before the 1980s.
Why Older Barrington Homes Need Special Attention
Many Barrington houses, whether it's a mid-century ranch or a historic home, have existing plumbing that wasn't set up for today's bath fixtures. Galvanized supply lines and cast iron drains are still common in older properties. Both can be trouble when you start demolition. Corroded pipes may leak or clog, and you could find original clay tile drain lines. Our crew checks these conditions early, as you never want to tile a new shower over a failing drain pipe. Homes with slab foundations or tucked-in basement baths will need a close look at how the drain and vent run, since moving plumbing under concrete is a bigger project.
Planning the Conversion
The first step is deciding where the new shower will fit and how big it can be. A standard tub is about five feet long, but walk-in showers come in all shapes. Sometimes, framing or plumbing behind the wall limits your choices. We always measure wall-to-wall and look at the ceiling height. If your home has low ceilings or unusual angles, that affects the type of shower door and hardware you can use.
Accessibility is another reason many Barrington families choose this upgrade. Walk-in showers work better for aging in place or simple day-to-day convenience. If you want a zero-threshold entry, we'll need to see if there's enough depth for a proper sloped shower pan without cutting into structural framing.
Key Plumbing Steps We Tackle
- Shut off the water at the main to protect the house during demolition.
- Remove the old tub and expose the drain and supply lines. We check for signs of corrosion or outdated materials like galvanized pipe.
- Inspect and upgrade the drain trap if needed. A new P-trap is standard. If the original is cast iron or too small, we replace it for proper drainage.
- Adjust water supply lines (usually 1/2-inch copper or PEX in newer remodels) to the new valve height and location.
- Install new shutoff valves when access is easy, since future repairs are much simpler if this is done now.
- Test for leaks before closing walls or setting tile. This is where experience counts, we often catch minor drips or issues the first time around.
We also look for signs of moisture problems in walls or subfloors, which are common in older homes with clay-rich soil and a moderate water table. If you notice musty smells or stains, this is the time to address them with proper waterproofing. Sometimes, we pair this work with drain cleaning to ensure the new shower drains as it should.
Fixture Choices and What to Watch Out For
Walk-in showers offer a range of fixtures, from simple single-handle valves to multi-jet systems. Barrington's municipal water is moderately hard, so we recommend fixtures that are easy to clean and less prone to mineral buildup. Solid brass or stainless trim holds up well here. Larger rain heads and handheld sprayers are popular, but it's smart to check your home's water pressure and the capacity of your water heater before adding extra features. If you need an upgrade, see our water heater services.
If your bathroom is on a slab or in the basement, be aware that routing new drains can be tricky. Many Barrington homes have clay soils, and shifting or swelling soil can affect old pipes. We frequently inspect for cracks or roots at this stage and may suggest pipe repair and repiping if anything is questionable.
Dealing with Surprises During Demolition
Once the old tub is out, it's common to uncover hidden problems. Water leaks around the old drain, rotted subfloors, and even past repairs done with the wrong materials show up often. We've seen unexpected issues with original cast iron traps and corroded galvanized supplies. Addressing these problems up front saves major headaches later.
If you find stains or mold in the walls, this is the best time to handle it. For stubborn leaks or concerns about hidden water damage, our leak detection and repair team uses non-destructive testing to pinpoint trouble spots before finishing the job. If your project includes new faucets or grab bars, our faucet and fixture installation crew can make sure everything fits safely and securely.
Final Steps and Ongoing Maintenance
After new plumbing is roughed in and tested, we set the shower pan and waterproof all seams before tiling. In homes with a history of basement seepage or a moderate water table, we often recommend checking sump pits and pumps. If you have a bathroom below grade, make sure your sump pump setup is ready, especially as the new shower adds water use to the system.
With proper planning and expert plumbing, a tub-to-shower conversion improves both comfort and value. Replacing old, worn-out pipes during the remodel reduces the chance you'll need another major fix down the road.
