Cost GuideUpdated July 7, 2026
Many older homes in La Salle were built with bathtubs as the standard. As needs change, we often get questions about replacing an outdated tub with a walk-in shower. This job isn't just about new tile or fixtures. With the mix of historic homes and decades-old plumbing in our area, you need to plan for more than just the visible updates. Hidden plumbing issues or old pipes are common and can impact both price and project timeline.
Why Tub-to-Shower Conversions Matter Around La Salle
We see a lot of mid-century bungalows and houses here that haven't had a major remodel in 40 years, or more. Many homeowners want a walk-in shower for easier access, to update the look, or to improve drainage. With our area's heavy clay soil and high water table, reliable drains are important. Some older homes still have galvanized or cast iron pipes under the bathroom floor. Those can corrode, clog, or break, so a shower conversion is a good time to address bigger plumbing concerns.
What Impacts the Cost?
The price to swap a tub for a walk-in shower covers more than the new tile or glass door. Expect costs to vary depending on these factors:
- Plumbing Layout: If the new shower base goes in the same spot as the old tub, that keeps things simpler. Moving the drain often means opening up the subfloor and reworking supply lines.
- Drain Pipe Condition: Older La Salle homes may have rusted or constricted cast iron or galvanized drain lines, which can require full or partial replacement. Shower drains need proper venting and slope to prevent slow draining and odors.
- Water Supply Pipes: If your current lines are old galvanized, they may restrict water pressure. We often recommend updating them to PEX or copper for better flow and fewer future leaks. More on that at our pipe repair and repiping page.
- Unexpected Leaks or Water Damage: Tubs and showers can hide slow leaks. If there's water damage to the subfloor or framing under your tub, repairing that adds to the price.
- Fixture and Tile Choices: Custom glass, natural stone, and high-end fixtures drive up the budget fast. Standard acrylic bases and basic tile are more affordable and durable for most families.
Typical Steps in a Tub-to-Shower Conversion
Every home is different, but most projects follow these steps:
- Turn off water and safely disconnect the supply lines to the tub.
- Demo and remove the old tub, checking for mold or rot underneath.
- Inspect waste and vent lines for corrosion or improper slope.
- Adjust or move the drain to fit the new shower base if needed.
- Replace old or damaged water supply pipes when possible.
- Install a new shower pan, waterproofing, and tile or solid-wall surround.
- Set new valves, showerhead, and controls. Check for code compliance and leak test everything.
Our crew always checks for hidden issues during removal. Many La Salle homes have had multiple smaller repairs over the years, so you can run into layers of old tile, patchwork pipes, or even shoddy electrical work nearby.
Plumbing Risks Unique to La Salle's Older Homes
The age of local homes and our humid continental climate both play a role. Cold winters and freeze-thaw cycles put extra stress on any plumbing close to exterior walls. Heavy clay soil and a high water table can make drainage and waterproofing even more important, especially if your home's foundation has settled over time.
If your existing tub drain connects to an older clay-tile or cast iron sewer line, you might want a camera inspection before the new shower goes in. We handle this as part of our sewer line services and can catch root intrusion or collapsed sections before they ruin your new bathroom.
Some homes in our area still have branch lines or drum traps that aren't up to today's standards. These can cause slow drains or even hidden leaks behind finished walls. We look for these issues up front so there's no surprise later.
Warning Signs and Practical Tips Before You Start
- Water stains, mildew, or soft spots on the bathroom floor are clues to a hidden leak.
- Low water pressure at the tub or inconsistent hot water may point to aging supply lines or a struggling water heater. We cover water heater service and replacement at our water heater services page.
- Frequent clogs or slow draining can signal corroded or undersized drain pipes. Learn about our drain cleaning process if this is a problem in your home.
- If your home is 50 years old or more, assume at least some steel or cast iron pipe remains below the floor. Consider updating these during your remodel for less hassle down the road.
- Always ask for a licensed plumber to handle any supply or drain work behind the walls. DIY fixes can fail inspection and lead to long-term water damage.
Getting Accurate Estimates and Planning for the Unexpected
No two bathroom remodels cost the same, but there's usually more to the final bill than just new tile or a fancy shower door. Surprises like rotten subfloor, obsolete valves, or leaking connections are fairly common in local homes. We take time during our initial walkthrough to inspect main shutoffs, test water pressure, and look for signs of past DIY plumbing repairs.
If your remodel includes new faucets, showerheads, or toilets, we also offer faucet and fixture installation so everything matches and works smoothly. For bigger updates like moving supply lines or relocating the shower entirely, costs will naturally be higher. Detailed estimates and clear communication help avoid headaches later.
