Upgrading a bathroom is one of the most effective ways to enhance a home’s functionality, value, and overall appeal. One of the most popular renovation choices today is changing a bathtub to a walk-in shower. This transformation is especially attractive to homeowners who want a modern, spacious, and accessible bathroom design that suits evolving needs.
Whether you're looking to optimize a small bathroom with a bathtub, plan for future accessibility, or simply improve day-to-day convenience, a bathtub to shower conversion offers a practical solution. In this guide, we’ll cover everything you need to know—from design ideas to step-by-step instructions, material choices, cost breakdowns, and frequently asked questions.
Why Homeowners Are Changing BathTub to Walk-In Shower Conversion
Many homeowners are changing a bathtub to a walk-in shower as part of broader bathroom renovations or due to a specific lifestyle change. The benefits go beyond aesthetics, touching on space efficiency, safety, and market value.
A small bathtub to shower conversion instantly opens up more usable space. Bathtubs often dominate the footprint of a bathroom, whereas a walk-in shower can be tailored to fit corner spaces or built flush to the wall. This helps create a sense of openness and makes daily routines more efficient.
A change from a tub to a walk-in shower is ideal for aging individuals or those with limited mobility. Stepping over a tub wall can be hazardous, especially in homes without grab bars or non-slip surfaces. A low- or no-threshold walk-in shower improves safety and independence, key concerns for seniors or those planning to age in place.
Real estate trends show that modern bathrooms with walk-in showers are increasingly attractive to potential buyers. While it’s often wise to keep at least one tub in the house for families with children, converting one bathtub to a shower, particularly in a master or guest bathroom, can add value and aesthetic appeal.
Before starting a bathtub-to-shower conversion, it’s worth evaluating if this change aligns with your household’s long-term needs.
Walk-in showers tend to align with a clean, minimalist, and spa-like design language. Glass doors, stone tiles, and matte black fixtures offer a modern look, while bathtubs are often found in more traditional or vintage-inspired layouts.
Cleaning a tub usually involves kneeling or bending, which can be physically demanding. In contrast, walk-in showers with seamless acrylic or tiled walls are easier to maintain. Frameless glass doors and non-porous surfaces also help reduce mildew buildup. Check out 3 secrets to keeping your bathtub squeaky clean .
From contemporary to compact spaces, bathroom tub shower ideas abound for homeowners considering this upgrade.

Start by evaluating the current layout of your bathroom. Most tubs are around 60 inches in length, which aligns well with standard shower kits or tiled enclosures. Measure the width, depth, and height of the space you’re working with.
Key considerations:
This is also the time to decide whether you'll go with a curbed or curbless (barrier-free) shower. Curbless designs offer superior accessibility but may require subfloor modifications.
Tip: For safety, ADA guidelines suggest a minimum interior shower size of 36 x 36 inches, though most walk-in showers use a 60 x 30-inch footprint.
Removing the bathtub is often the most labor-intensive phase of the project. Here’s how to do it safely:
If applicable, also remove any shower tub combo units, shower stalls, or surround systems. Always wear safety gear, especially gloves and goggles.
Once the tub is out, assess the plumbing condition and wall structure. You may need to:
Wall preparation includes installing cement board (Durock or HardieBacker), especially if you’re planning to tile. This board must be waterproofed using materials like RedGard or a PVC liner.
If the area previously had leaks, now is the time to inspect and fix the bathroom tub area, addressing any issues with water damage before continuing.
If mold or damage is found during demo, our guide to repairing solid surface bathtubs may offer insights into materials used for replacements.
Next, place the new shower base or shower pan. Whether it’s a pre-fabricated acrylic base or a custom mud bed, proper slope toward the drain is critical to avoid pooling water.
Common options:
Once the base is installed:
Panel materials range from solid surface, acrylic, tile, stone veneer, or laminate panels—each offering varying levels of cost and customization.

To complete the walk-in shower installation, apply these final elements:
If you're using tile, be sure to seal grout lines and allow drying time per manufacturer instructions.
Optional upgrades may include:
These bathtub replacement options not only enhance usability but also elevate the entire look and feel of the bathroom.
The cost of a bathtub to shower conversion can vary significantly depending on materials, bathroom condition, location, and whether you’re hiring a contractor or going the DIY route. Understanding these variables helps you plan more effectively and avoid unexpected expenses.
Based on current industry data, here’s a general pricing breakdown:
| Type of Conversion | Estimated Cost Range |
|---|---|
| Basic DIY Shower Kit | $1,000 – $3,000 |
| Mid-Range Tile Installation | $3,500 – $7,000 |
| High-End Custom Shower | $8,000 – $15,000+ |
| Walk-In Shower with Accessibility Features | $5,000 – $12,000 |
The cost of the bathtub to shower conversion is most affordable if plumbing remains unchanged and you use a prefabricated shower kit. Pricing increases with tile customization, structural work, or accessibility modifications.
If you’re planning a convert bathtub to walk-in shower project in a city with a higher cost of living or an older home with outdated plumbing, expect to be on the higher end of the spectrum.
If budget is a concern, acrylic bathtubs may offer excellent value with lower upfront costs.
Several factors influence the final budget:
1. Material Choices
2. Labor and Contractor Fees
Hiring a licensed professional can cost $75–$150 per hour. Expect higher rates for plumbing rework, tile setting, or major structural changes.
3. Permits and Inspection Fees
Many cities require permits for bathroom remodels, especially if plumbing is being modified. Permits can range from $100–$500, depending on your local regulations.
4. Demolition and Disposal
Removing an old cast-iron tub or retrofitting vintage plumbing adds cost. Don’t forget to factor in dumpster rentals or waste disposal if you’re DIYing.
5. Finishing Touches
Built-in shelves, grab bars, and upgraded fixtures contribute to both functionality and cost.
Note: Be cautious with budget walk-in shower kits—cheap materials can crack or stain over time, leading to more expenses later.
Visualizing the impact of a tub to walk-in shower before and after conversion can help you see the value in this project. These real-world examples highlight how different design choices can change both the function and aesthetic of a bathroom.
Example 1:
Before – A dated alcove bathtub with a plastic surround and limited access.
After – A walk-in shower with subway tile walls, a built-in bench, a frameless glass door, and a handheld sprayer.

Homeowners often hesitate to change a bathtub to a walk-in shower in compact spaces, fearing it will reduce usability. However, a properly designed small bathroom remodel with tub and shower features can actually increase usable space.
Real-life remodels show that removing a bulky tub can free up enough space for better storage, larger vanities, or even just breathing room.
When you decide to change your tub to a walk-in shower, the design possibilities go far beyond simply removing the bathtub. Modern walk-in showers combine form and function to deliver a space that’s easy to use and visually impressive. Let’s explore the most popular and effective walk-in shower design trends for 2025.
Frameless glass showers continue to dominate contemporary bathroom design. These showers:
A key advantage is that they can be customized to fit almost any layout—whether you’re doing a bathtub to walk-in shower conversion in a corner or across the full width of the room.
For those seeking more privacy, frosted or textured glass options are also available.
Built-in benches are not only useful for individuals with mobility concerns but also convenient for shaving or simply relaxing under the warm water. Adding a bench to your walk-in shower also helps conceal awkward plumbing features, such as dryer vents or misaligned walls, which some homeowners discover after removing the tub.
Shower niches—recessed shelving built into the wall—are now preferred over wire caddies or corner shelves. They’re more visually seamless and provide essential storage without intruding on space.
If your conversion is being done with long-term use in mind, consider accessibility from the beginning. Barrier-free showers, also called curbless or zero-threshold showers, are ideal for wheelchair users and seniors.
Key features to consider:
Adding these features during the initial walk-in shower installation phase is more cost-effective than retrofitting later. These elements also align with ADA-compliant design standards and can future-proof your bathroom.

Here are answers to the most commonly searched questions from homeowners considering a bathtub replacement or a walk-in shower upgrade. These answers are grounded in both practical renovation experience and real-world product use.
To change a tub to a walk-in shower, the basic steps include:
This process takes 2–7 days depending on complexity, and longer if custom tile or plumbing modifications are involved.
If your bathtub sits in a standard alcove (three-sided enclosure), you already have a good setup for a walk-in shower. Many walk-in shower kits are designed to fit these dimensions. The conversion includes:
Contractors typically prefer these projects due to minimal structural rework.
Yes, if you're seeking safety features but want to retain a soaking option, a walk-in tub is a viable alternative. These tubs have sealed doors, built-in seating, and anti-scald features.
While this isn't the same as a walk-in shower, it’s often considered by seniors or caregivers who need water immersion without stepping over a high tub wall.
To remove an old shower tub combo:
Be cautious with drywall or plaster to avoid damaging studs. If you plan to convert the combo to a walk-in shower, you'll likely reuse the footprint.
If you're retaining the tub but want to upgrade the shower surround:
Use sanded grout and seal the corners with caulk to prevent cracking. This is a great option when seeking partial upgrades without full bathtub replacement.
In some cases, yes. You would need to ensure that plumbing lines match the tub configuration and the space meets code requirements. Replacing a shower with a bathtub may appeal to families with young children or homes where a tub is essential for resale value.
If you’re still weighing your options or your household includes individuals with different needs, it’s worth exploring bathtub replacement ideas beyond a full shower conversion. There are alternatives that retain both convenience and versatility.
Walk-in tubs offer a soaking experience while eliminating the need to step over a traditional tub wall. These models typically include:
While walk-in tubs are ideal for elderly users or people with disabilities, they do require more water and a longer fill/drain time compared to standard bathtubs or showers.
Walk-in showers, by contrast, are easier to clean, take up less space, and are better suited for fast-paced lifestyles. Your choice will ultimately depend on who uses the bathroom most and what long-term accessibility needs may arise.
Still want the option to soak but don’t want to lose a walk-in experience? Consider a shower/tub combination with updated features such as:
These combinations are practical for families and work well in guest bathrooms. They also simplify bathtub replacement for homeowners who don’t want to fully commit to one format over the other.
For larger bathrooms or high-end remodels, small freestanding bathtubs can be installed next to walk-in showers. This setup:

Converting a tub into a shower isn’t complicated, but mistakes during planning or installation can lead to leaks, poor usability, or code violations. Below are the most common errors to avoid in your bathtub to walk-in shower conversion.

A curbless walk-in shower is the gold standard for aging-in-place design. It:
Pair it with grab bars placed near the entry, controls, and seating area. Many modern options are stylish and can double as towel racks.
If you're aiming for full accessibility, follow the Americans with Disabilities Act (ADA) guidelines, including:
While not legally required in private homes, these guidelines ensure long-term comfort and safety.
As sustainability becomes more of a priority for homeowners, incorporating eco-friendly walk-in shower features into your bathtub to shower conversion can help reduce water and energy consumption, without sacrificing comfort or design.
Modern low-flow showerheads use 1.5–2.0 gallons per minute (GPM) compared to older models that use 2.5 GPM or more. Advanced technologies now allow these fixtures to:
By switching to a low-flow showerhead, the average household can save hundreds of gallons of water each year.
