If stepping over a high bathtub wall has become difficult, a bathtub conversion kit can create a lower step-through opening without replacing the entire tub. These kits require cutting into the existing tub, so fit and installation matter. One important distinction: the options below use an opening with a removable or covering insert; they are not conventional bathtubs with a hinged, watertight door. Check the product details and measure your tub carefully before choosing.

Quick Tub Walk-In Conversion Kit with Cap: Best for Keeping Bathing as an Option
This Quick Tub kit turns a compatible existing bathtub into a shower with a lower step-through opening. Its main advantage over the insert-only Quick Tub option is the included Quick Tub Cap, which lets you close the opening and switch back to using the tub for soaking. The cap is described as a way to move between the two uses in seconds.
The kit includes the insert, cap, cutting template, two tubes of industrial-strength adhesive, an angled nozzle, and instructions. It is designed for steel, fiberglass, and cast iron tubs, but the narrow size makes measuring especially important. The maker provides a sizing guide and recommends checking it before buying.
Installation involves tracing a template, cutting the tub, and bonding the insert in place. That can be less involved than replacing a bathtub, but cutting an existing fixture is still a significant DIY task. The product information describes installation in a few hours, but your actual project may depend on the tub and your skill level. This option is best for someone who wants a lower shower entry while keeping the possibility of a bath.
Pros:
- Includes a cap for switching back to soaking-bath use.
- Designed for steel, fiberglass, and cast iron tubs.
- Includes a template, adhesive, nozzle, and instructions.
- Offers a conversion option without a full tub replacement.
Cons:
- The narrow size requires careful measurement before ordering.
- Installation requires cutting into the existing tub.
Verdict: Choose this Quick Tub kit if you want a step-through shower opening and the included cap to retain access to soaking baths.
CleanCut Step Tub Conversion Kit: Best for a Straightforward Step-Through Opening
The CleanCut Step kit is made to lower the entry point of an existing bathtub, making it easier to step in and out than a full-height tub wall. It is a step-through conversion rather than a door-equipped bathing system, so it suits households that mainly want easier shower access and do not need an insert to close the opening for baths.
This large kit includes a walk-through insert, support structure, industrial-grade adhesive, waterproof wrap, cutting template, and installation guide. It is designed for use with most fiberglass, steel, and cast iron bathtubs. “Most” does not mean every tub, however, so check the manufacturer’s fit guidance and your tub’s measurements before ordering.
The supplied support structure and waterproof wrap are useful parts of the package, while the template and guide support the cut-and-install process. As with other conversion kits, installation requires altering the tub itself. If you are not comfortable making a precise cut or bonding the insert, consider getting help from a qualified installer. Compared with the Quick Tub kits, this one does not list a cap for restoring full soaking-bath use.
Pros:
- Creates a lower step-through entry without replacing the whole tub.
- Includes a support structure and waterproof wrap.
- Designed for most fiberglass, steel, and cast iron tubs.
- Includes a cutting template and installation guide.
Cons:
- Does not list a removable cap for returning the tub to soaking use.
- Fit depends on the existing tub and requires careful installation.
Verdict: This is a practical choice if your main goal is a lower shower entry and you do not need to close the opening for bathing.
Quick Tub Narrow Conversion Kit: Best for a Shower-First Setup
This Quick Tub kit is designed to convert a compatible tub into a walk-in shower by creating a step-through cut-out. It has the same basic conversion approach as the Quick Tub kit above, but its listed contents do not include the cap. The product information says you can pair it with a Quick Tub Cap to switch back to a full soaking tub, so confirm whether a cap is available and what is included before choosing this option.
The package includes the insert, cutting template, two tubes of industrial-strength adhesive, an angled glue nozzle, and instructions. It is intended for steel, fiberglass, and cast iron tubs. Its narrow size means it is important to use the sizing guide rather than assuming it will fit because your tub looks similar to the product image.
The smooth, easy-to-clean surface is intended to match the existing tub, and the kit is positioned as an alternative to a full bathroom tear-out. Still, this is not a no-tools update: the tub must be cut and the insert bonded in place. It is a better fit for a shower-focused household or for someone willing to source the cap separately if restoring bath use is important. The cap-included Quick Tub option is more complete for buyers who want that flexibility immediately.
Pros:
- Creates a lower-entry shower using the existing tub.
- Includes a template, adhesive, nozzle, and instructions.
- Designed for steel, fiberglass, and cast iron tubs.
- Can be paired with a Quick Tub Cap for bath use.
Cons:
- The cap is not listed as part of this kit.
- Requires an accurately measured tub and a cut-out installation.
Verdict: Pick this kit if you want the Quick Tub step-in conversion and do not need a cap included in the same package.
CleanCut Convertible Tub Kit: Best for Keeping the Option to Take a Bath
The CleanCut Convertible kit is designed to create a lower step-through opening while preserving the option to use the bathtub. Its removable center insert locks into place and can be removed to switch between shower access and bathing. Unlike a fixed step-through conversion, this design is aimed at households that want to keep both uses available.
The kit includes the convertible unit, support structure, industrial-grade adhesive, waterproof wrap, cutting template, and installation guide. It is presented as an alternative to replacing the tub or undertaking a full bathroom remodel. The product description does not specify the tub materials it fits, so check compatibility with the manufacturer before ordering rather than relying on the material list for another CleanCut kit.
The removable insert adds flexibility, but it also means there is a part to secure in place when you want to use the tub as a full bath. The kit still requires a cut-out installation, so careful fitting and bonding are central to the result. Compared with the Quick Tub option, this CleanCut kit emphasizes a removable, locking insert rather than a separately described cap.
Pros:
- Removable insert lets you switch between shower access and bathing.
- Includes a support structure and waterproof wrap.
- Comes with adhesive, a cutting template, and an installation guide.
- Can improve access without replacing the entire bathtub.
Cons:
- Requires cutting into the existing tub for installation.
- The product details provided do not specify compatible tub materials.
Verdict: Choose the CleanCut Convertible if keeping a removable insert for occasional bath use is a priority and you can confirm that your tub is compatible.
How to Choose a Bathtub Conversion Kit With a Door
Know what “door” means for this type of kit
These products modify an existing bathtub by creating a lower step-through opening. They do not work like a new walk-in tub with a conventional hinged door. Some kits include a cap or removable insert that closes the cut-out so you can use the tub for bathing. If you need a sealed entry door or a specific accessibility feature, confirm the product design before buying.
Measure your tub and confirm the fit
Fit is one of the most important parts of choosing a conversion kit. The Quick Tub options are listed as narrow and come with sizing guidance; the CleanCut Step kit is listed as large and is described as fitting most tubs made from certain materials. Use the maker’s instructions and sizing guide to check your tub, rather than judging by appearance alone. For the CleanCut Convertible, verify material compatibility directly because it is not specified in the product information provided here.
Decide whether you need to keep bathing in the tub
If you only need a step-through shower opening, an insert-only conversion may meet your needs. If you want to keep using the tub for soaking, look for a kit that includes a cap or a removable insert. The Quick Tub kit with cap includes one in the package. The other Quick Tub kit can be paired with a cap, but its listed contents do not include one. CleanCut’s Convertible kit uses a removable center insert.
Check the included installation parts
Compare the contents, not just the product name. The kits vary in what they include: some list a support structure and waterproof wrap, while others include adhesive, a cutting template, and a cap or removable insert. Make sure the package has the parts you need and read the full instructions before starting the project.
Be realistic about installation
These kits require cutting into an existing tub and bonding an insert in place. A template and instructions help guide the work, but the installation still calls for careful measuring and cutting. If you are not comfortable modifying your tub, consider arranging professional help. Before starting, review the product’s instructions and confirm that the kit is suitable for your tub.
Think about the access you need day to day
A lower entry can make stepping into a tub easier, but a conversion kit is not a complete bathroom safety assessment. Consider the needs of everyone who will use the shower and whether other changes may be needed for comfortable access. If mobility or balance is a concern, seek advice from an appropriate professional about the setup that suits your situation.

Final Recommendation
