How Much You Will Spend on a Bath to a Walk-In Shower?
Converting your bathtub to a walk-in shower is one of the most popular home improvements in Eastern Michigan. Whether you’re planning for aging-in-place, need better accessibility, or simply prefer the convenience of a shower, this upgrade typically costs between $3,000 and $20,000 depending on materials and features.
At Bath Planet of Eastern Michigan, we’ve completed hundreds of these conversions. This guide breaks down the costs, process, and what you can expect from your investment.
The Step-by-Step Conversion Process
Pre-Installation Preparation
Before any demolition begins, our team conducts a thorough assessment of your existing bathroom. This includes measuring the space, evaluating the current plumbing configuration, and identifying any potential challenges such as structural issues or outdated electrical systems. We protect surrounding areas with heavy-duty plastic sheeting and remove any obstacles that might interfere with the work.
The water supply is shut off at the main valve, and all plumbing connections to the existing bathtub are carefully disconnected. This preparation phase is crucial for ensuring the project proceeds smoothly and prevents water damage to your home during the conversion process.
Bathtub Removal Process
Removing an existing bathtub requires both skill and proper equipment, as bathtubs can weigh anywhere from 60 pounds for basic fiberglass units to over 300 pounds for cast iron models. Our team begins by disconnecting all plumbing connections, including the faucet assembly, drain, and any shower fixtures attached to the tub.
The surrounding materials—whether tile, fiberglass surround, or other wall coverings—are carefully removed to expose the bathtub’s mounting points. We use specialized tools to cut through decades of caulk and sealant without damaging the underlying structure. For cast iron tubs, we sometimes need to cut the tub into manageable pieces for safe removal, while fiberglass and steel tubs can often be removed intact.
The removal process requires careful maneuvering through tight bathroom spaces and doorways. Our experienced installers use proper lifting techniques and equipment to prevent injury and property damage. All debris is safely disposed of according to local regulations, with many materials being recycled when possible.
Site Preparation for Walk-in Shower
Once the bathtub is removed, we thoroughly inspect the exposed subfloor and wall surfaces for any signs of water damage, rot, or structural issues. This is often the first time these areas have been accessible in years, making it an important opportunity to address any underlying problems.
The subfloor is reinforced as needed to support the new shower system. We install proper subfloor materials that can withstand moisture and provide a stable foundation for the shower base. Any necessary structural modifications are completed at this stage.
Plumbing modifications typically include relocating the drain to accommodate the new shower base, updating supply lines to current code requirements, and installing new shut-off valves for easier maintenance. If the existing plumbing is outdated or shows signs of wear, we recommend updating it to prevent future problems.
Walk-in Shower Installation Process
The shower base installation is critical to the long-term success of your conversion. We ensure proper leveling and adequate support, connect the base securely to the drain system, and thoroughly test for leaks before proceeding. The base must be perfectly level to ensure proper drainage and prevent water pooling.
Wall preparation involves installing cement board or other appropriate substrate materials that provide a stable, waterproof foundation for the shower walls. We apply waterproof membranes according to manufacturer specifications, ensuring complete coverage and proper sealing at all penetrations and joints.
The shower wall installation requires precise measurements and careful cutting to ensure a perfect fit. Wall panels are secured with appropriate fasteners and all joints are sealed to create a completely watertight enclosure. We pay special attention to corners and areas around fixtures, as these are the most common locations for water intrusion.
Fixture installation includes mounting the shower valve and trim components, installing the showerhead and any additional spray features, and adding safety elements like grab bars and built-in seating. If you’ve chosen a shower door system, it’s installed and adjusted for proper operation and sealing.
Cost Breakdown: What You're Really Paying For
Labor Costs
Labor accounts for approximately 60–70% of the total project cost, reflecting the expertise required for safe demolition, plumbing upgrades, and precise installation. Removing a bathtub takes 4–6 hours, with extra care for heavy cast iron units. Plumbing modifications—often the most complex part—can take 6–8 hours, especially if outdated systems need upgrades.
Installing the new shower system, including waterproofing and fixtures, typically takes 8–12 hours depending on design complexity. Final steps like caulking, cleanup, and quality checks add another 4–6 hours.
In Eastern Michigan, labor rates range from $75–$125 per hour, depending on the trade. Your project benefits from a team of licensed plumbers, skilled installers, and detail-focused finishers.
Materials, Styles and Components
The materials you choose play a key role in the durability, appearance, and functionality of your walk-in shower. The shower base is foundational, and its quality affects drainage, safety, and long-term performance. Options range from standard acrylic to premium models with built-in features like seating or textured surfaces.
Wall surrounds come in a wide variety of materials, from simple, easy-to-clean acrylic to more decorative or natural-looking options like composite panels and stone finishes. These choices impact both aesthetics and maintenance needs.
Fixtures and hardware—such as shower valves, trim kits, and showerheads—offer various styles and features, from basic functionality to advanced controls and designer finishes. Accessibility upgrades like grab bars or built-in seating can also enhance comfort and safety.
Overall, higher-end shower styles and materials tend to provide greater durability, easier cleaning, and a more refined appearance, making them a worthwhile investment for long-term value.

Return on Investment for Walk-In Showers
Converting a bathtub to a walk-in shower is one of the most valuable bathroom upgrades, offering an estimated return on investment (ROI) of up to 70–85%, especially in markets like Eastern Michigan. According to data from Remodeling Magazine’s 2023 Cost vs. Value Report, bathroom remodels consistently rank among the top home improvements for resale value.
Beyond financial return, these conversions enhance accessibility and safety—key selling points for older buyers or families with mobility needs—often reducing time on the market. Walk-in showers also lower long-term maintenance needs, thanks to fewer crevices for mold, no shower curtain buildup, and reduced leak risks.
Upgraded fixtures, lighting, and ventilation further boost comfort and energy efficiency, adding practical value that extends well beyond aesthetics. For homeowners planning to age in place, the improved safety and independence can make the investment invaluable.
