Do I need to update my plumbing during a tub to shower conversion?

In older Big Rock homes, the original pipes are often galvanized steel or cast iron, which can be corroded or undersized for modern fixtures. We recommend inspecting and possibly replacing these lines while the walls and floors are open, so your new shower will drain and supply water reliably.

How long does converting a tub to a walk-in shower typically take?

The full process usually lasts several days to a week, depending on what we find behind the tub. Uncovering old leaks, slow drains, or needing to upgrade supply lines may add time, but addressing those now prevents bigger issues down the road.

Will a walk-in shower affect water pressure or hot water supply?

If you have good existing plumbing and an adequate water heater, you shouldn't notice a drop in pressure or hot water for showers. However, hard water can impact heater performance, so we check for buildup and offer water heater service if needed as part of the remodel.

Is a walk-in shower better for homes with basement seepage or high water tables?

A walk-in shower won't cause seepage by itself, but adding one may be a good time to check sump pumps and drainage if your home is prone to basement moisture. We look at overall drainage and waterproofing to protect your investment during any major update.

Tub to Walk-In Shower Conversion Big Rock

MaintenanceUpdated June 11, 2026

Many Big Rock homes still have traditional bathtubs that don't fit homeowners' current needs. Whether you're facing mobility concerns, looking to update an older house, or want a low-maintenance bathroom, converting a tub into a walk-in shower is one of the most practical upgrades you can make. Our team has worked with plenty of local plumbing systems, and we know the common issues that come up when swapping a tub for a shower, especially in homes with older galvanized supply lines or clay-rich soils that affect drainage.

Why Older Big Rock Homes Benefit from Shower Conversions

Homes built decades ago often feature cast iron or galvanized steel piping, and the bathrooms were designed around full tubs. Over time, these pipes corrode or develop leaks, and the deeper footprint of a tub can make plumbing access difficult. When you switch to a walk-in shower, our crew can address hidden leaks, reroute supply lines for better water pressure, and upgrade drain lines if necessary. This is also a good time to inspect for mineral buildup, common here due to Big Rock's moderately hard water, which can affect both hot and cold fixtures.

Main Steps in Tub to Shower Conversion

Remove the existing tub and old surround
Inspect supply lines and drain for corrosion or leaks
Upgrade or repair piping as needed, especially if galvanized or cast iron is present (pipe repair and repiping details)
Install an appropriate shower base and ensure correct slope for drainage
Fit new wall surrounds and update fixtures (faucet and fixture installation options)
Test for leaks, proper drainage, and finish with sealed tile or waterproof panels

This process can reveal hidden issues like slow drains or deteriorated waterproofing. Since many Big Rock homes have clay soils and a high water table, a thorough check of the P-trap, drain line, and waterproofing is important during any bathroom remodel. If you notice persistent slow drainage, our drain cleaning services can resolve clogs before installation is complete.

Plumbing Considerations Unique to Big Rock

Our village has a mix of housing ages, and the clay soil here can put extra pressure on buried pipes, especially after freeze-thaw cycles in winter. If your bathroom is on the main floor or basement, we often examine nearby sump pits and check valves, since water from showers can add to sump pump workload. Basement seepage is another thing we see, especially in homes near the Blackberry Creek or with older waterproofing. For homeowners experiencing this, reviewing sump pump options as part of a remodel makes sense.

Warning Signs Your Tub Conversion Needs a Professional Plumber

Water takes a long time to drain, or backs up around the old tub
You see corrosion or mineral flakes around valves or supply lines
There is musty odor or visible water staining on nearby walls or floors
You hear knocking or rattling in the pipes when water runs (leak detection and repair can pinpoint trouble)
Hot water doesn't last or is inconsistent, pointing to a possible issue with the water heater (water heater service can help here during a full bathroom update)

Tub-to-shower conversions expose plumbing you don't usually see, so it's the perfect time to address these problems. Fixing them now saves money and hassle later.

Local Codes and Fixture Upgrades

Our crew always installs new shower bases and enclosures to meet Illinois plumbing code. Every remodel includes proper venting and a correctly sized drain, which is especially crucial if your previous tub used a smaller pipe. We also recommend modern fixtures with anti-scald protection and easy-access controls. For homes with hard water, using fixtures designed to resist mineral buildup will help keep your new shower working smoothly for years.

Planning for the Future

Walk-in showers work well for aging-in-place or accommodating family members with limited mobility. Adding a new shower can help increase usable space while making your bathroom easier to clean and maintain. We always look at your home's whole plumbing system during any remodel, so nothing gets overlooked, especially in houses with older layouts or signs of previous leaks.
