A small bathroom does not always need a full remodel to make bathing easier. A tub cut-out conversion kit can lower part of your existing bathtub wall, creating a step-through entry while keeping the tub in place. If you want to keep the footprint compact, the options below focus on modifying an existing tub or adding shower hardware to a clawfoot tub. Check the fit and installation limits carefully: these products do not all solve the same problem, and most do not include a complete shower enclosure.

Our Picks: Best Small Bathroom Tub To Shower Conversion reviews
1. Quick Tub Wide Kit: A Straightforward Step-Through Option
The Quick Tub Wide is a cut-out insert for modifying an existing bathtub. After you cut an opening in the tub wall, the insert bonds into place to make a lower step-through entry. This approach can suit a small bathroom because it works with the tub already in the room rather than replacing it with a larger shower base.
The kit is described as compatible with steel, fiberglass, and cast-iron tubs. It includes an insert, cutting template, two tubes of industrial-strength adhesive, an angled nozzle, and instructions. The smooth white surface is intended to match the existing tub. The manufacturer also describes an optional Quick Tub Cap that can let you switch between shower access and a full soaking tub, but that cap is not listed among this kit’s included components.
The main decision is whether the wide size fits your tub. The supplied product information stresses measuring first and using the sizing guide. A cut-out conversion also permanently changes the tub, so it is important to understand the cutting and bonding steps before starting. This is a way to make entry easier, not a complete shower installation: confirm what shower fixtures, curtain, or enclosure you still need.
Pros:
- Designed to modify an existing tub instead of replacing it.
- Listed for steel, fiberglass, and cast-iron tubs.
- Includes a cutting template, adhesive, nozzle, and instructions.
- Can be paired with a separately sold cap, according to the product description.
Cons:
- Fit depends on careful measurement and choosing the correct size.
- Requires cutting and bonding the existing tub.
Verdict: Choose the Quick Tub Wide if your tub matches its sizing guide and you want a lower entry without replacing the tub.
2. Quick Tub Narrow Kit: A Smaller-Size Alternative
The Quick Tub Narrow uses the same basic idea as the wide version: cut an opening into the existing tub wall and fit the insert in place. It is intended for tubs that match the narrow-size guide, making it a useful option when the wide kit is not the right fit. The product description lists plastic as its material and white as its color.
Included parts are an insert, cutting template, two tubes of adhesive, an angled nozzle, and instructions. The kit’s compact approach may appeal if you want to retain the tub and avoid a larger replacement project. However, the description calls for measuring carefully and does not provide enough dimensions here to confirm fit from the product name alone. Use the manufacturer’s sizing information before ordering.
As with the wide model, this kit changes the tub wall but does not itself provide a showerhead or shower enclosure. The job also involves cutting the existing tub, so consider your tub’s condition and your comfort with the installation process. If the tub material or shape is uncertain, get guidance before making an irreversible cut.
Pros:
- Narrow-size option for tubs that do not match the wide kit.
- Includes the template and adhesive needed for the described conversion.
- Works with an existing tub rather than requiring a full tub replacement.
- White finish is intended to blend with a white tub.
Cons:
- Exact fit must be confirmed with the sizing guide.
- Installation requires cutting the tub wall and bonding the insert.
Verdict: The Narrow kit is worth considering when your measurements point to the narrow size; do not choose it simply because your bathroom is small.
3. CleanCut White Large: A Convertible Kit with a Removable Insert
The CleanCut Convertible kit is designed to create a step-through opening while retaining the option to use the tub for bathing. Its removable center insert locks in place to form a water-tight closure, then comes out when you want the opening for shower access. That dual-purpose design may suit a household where different people prefer showering or bathing.
The large, white kit includes the convertible unit, a two-part support structure, industrial-grade adhesive, waterproof wrap, cutting template, and installation guide. The listed product dimensions are 28.75 by 7 by 10.75 inches. Those figures describe the kit, not a guaranteed cut-out fit for every bathtub, so check compatibility and the installation instructions for your tub before buying.
Compared with the Quick Tub options, CleanCut clearly emphasizes the removable insert and includes a support structure and waterproof wrap. The trade-off is that this is still a cut-and-install conversion, not a no-modification accessory. The supplied details do not specify tub materials it fits, so confirm that point with the manufacturer if you are unsure about your tub.
Pros:
- Removable insert lets you switch between a step-through opening and a closed tub.
- Includes a support structure, adhesive, waterproof wrap, template, and guide.
- White finish and large size offer a clear option for matching tubs.
- Designed to avoid a full tub replacement.
Cons:
- Requires cutting the tub and fitting the kit correctly.
- Compatibility with specific tub materials is not stated in the supplied details.
Verdict: Pick the CleanCut White Large if retaining the option to take a bath matters and your tub is confirmed compatible.
4. CleanCut Beige Large: Same Convertible Design in a Different Color
This beige CleanCut kit has the same convertible purpose as the white large version: it creates a step-through opening, while a removable water-tight insert lets you close the opening for bathing. The beige color may be a better visual match for some older tubs or bathroom finishes, but check the product image and color details against your tub before choosing.
The listed kit includes the convertible unit, two-part support structure, adhesive, waterproof wrap, cutting template, and written installation guide. Its stated dimensions are 28.75 by 7 by 10.75 inches. As with the white version, those are product dimensions and do not replace checking the installation guide for your tub’s fit.
The key comparison is color: the product information describes the same core function and included components as the white CleanCut option. It still requires cutting and fitting the tub, and the supplied details do not specify which tub materials are compatible. If you are choosing between the two CleanCut kits, let your tub color and confirmed fit guide the decision rather than assuming the beige model is a different installation type.
Pros:
- Convertible design supports both shower entry and use as a bath.
- Includes a removable insert and support structure.
- Comes with adhesive, waterproof wrap, template, and instructions.
- Beige finish offers an alternative to white.
Cons:
- Requires cutting and careful installation.
- Check tub-material compatibility before purchase because it is not specified in the supplied details.
Verdict: Choose this version over the white CleanCut only if beige is a better match for your tub and you have confirmed fit.
5. Pyhomestrim Clawfoot Shower Kit: A Shower Add-On, Not a Tub Cut-Out
This product serves a different purpose from the tub cut-out kits. It adds shower hardware to a clawfoot tub; it does not lower the tub wall or create a step-through entry. The listed set includes a bathcock diverter faucet, shower riser, shower rod, support rods, showerhead, and curtain rings. It is relevant if you have a clawfoot tub and want to use it as a shower, but it is not the right choice if your main goal is easier access over a high tub wall.
The product description gives a rectangular shower-rod size of 48 by 27 inches and describes adjustable ceiling support lengths of 10, 18, or 28 inches before cutting. It also says the support can be attached to a wall or ceiling. Measure your room and check the placement of windows and surrounding surfaces before ordering, since the rod and supports need suitable installation locations.
In a small bathroom, the main appeal is that this is an add-on for an existing clawfoot tub rather than a tub replacement. The main limitation is just as important: it supplies shower hardware, not a lower tub entrance. It also has specific installation dimensions, so it is a niche pick rather than a general solution for converting a standard bathtub.
Pros:
- Provides a shower setup for a clawfoot tub.
- Includes faucet, showerhead, riser, rods, and curtain rings.
- Support design is described as adjustable for different room layouts.
- Useful when you want to keep a clawfoot tub and add shower functionality.
Cons:
- Does not create a step-through opening or improve access over the tub wall.
- Requires checking the listed rod and support dimensions against your room.
Verdict: Consider this kit only if you have a compatible clawfoot tub and need shower hardware, not an accessibility cut-out.
How to Choose a Small Bathroom Tub-to-Shower Conversion Kit
Decide whether you need easier entry or shower hardware
A tub cut-out kit lowers part of the tub wall to make entry easier. A clawfoot shower kit adds shower fixtures but leaves the tub wall as it is. Start by identifying the problem you want to solve. If stepping over the tub is the concern, focus on a cut-out conversion. If you already have a clawfoot tub and need a shower setup, the add-on hardware may be relevant.
Measure your tub and use the sizing guide
Do not select a kit based only on the word “wide” or “narrow,” or on the size of your bathroom. Measure the tub as directed by the manufacturer and compare those measurements with its sizing guide. The Quick Tub products specifically stress checking fit before purchase. For CleanCut, confirm fit and tub compatibility using the product instructions or manufacturer information, since the supplied details do not list compatible tub materials.
Check tub material and condition
The Quick Tub Wide is listed for steel, fiberglass, and cast-iron tubs; the Narrow model lists plastic as its material. These details do not establish that every tub in those material groups will fit. Check your tub’s material, shape, and condition against the specific kit requirements. Cutting and bonding a conversion insert into a damaged or incompatible tub could lead to a poor result.
Think through the installation before buying
Cut-out kits involve modifying the existing tub. The included templates and instructions help explain the process, but they do not remove the need for accurate cutting and bonding. Consider whether you have the tools and skills for the work, or whether you should ask a qualified installer. If the project involves changes beyond the kit, such as new shower plumbing or a shower enclosure, plan for those separately.
Choose between a fixed opening and a convertible insert
The Quick Tub kits are presented as step-in conversion kits, with an optional cap described separately. CleanCut highlights a removable insert that can close the opening for bathing. If you want to preserve the option of a full bath, confirm exactly which components are included and how the insert is installed and removed. Do not assume an optional accessory comes with the base kit.
Plan for the rest of the shower setup
A tub cut-out kit does not automatically provide a showerhead, curtain, or enclosure. Check what your bathroom already has and what you will need to add. In a tight room, also consider where a shower curtain or door will sit and whether it will interfere with the new entry. For the clawfoot kit, compare its rod and support dimensions with the actual space around your tub.
Consider safety beyond the tub opening
A lower entry can reduce the height you need to step over, but it does not make the entire bathing area slip-proof or provide a place to hold on. Think about the floor surface, grab bars, seating, and other access needs. If the bathroom is being adapted for a person with limited mobility, consider getting professional advice about the full layout and installation.
Frequently Asked Questions
Can a tub-to-shower conversion kit fit in a small bathroom?
A cut-out kit modifies the bathtub already in the room, so it does not require replacing the tub with a separate shower base. You still need to check the kit’s fit, and you may need separate shower fixtures or a curtain enclosure.
Do these kits replace the whole bathtub?
No. The Quick Tub and CleanCut products are designed to modify an existing tub with a cut-out and insert. The clawfoot kit adds shower hardware to a clawfoot tub; it is not a tub replacement or a cut-out conversion.
Do tub cut-out kits include a showerhead?
The supplied details for the Quick Tub and CleanCut kits do not list a showerhead. The Pyhomestrim clawfoot kit does include shower hardware, but it does not create a lower entry. Check what is already installed in your bathroom and plan for any missing components.
Can I still take a bath after installing a cut-out kit?
The CleanCut kits include a removable water-tight insert intended to close the opening for bathing. The Quick Tub description mentions an optional cap that can be purchased separately. Check the product listing to confirm what is included with the specific kit you choose.
How do I choose between the Quick Tub Wide and Narrow kits?
Use the manufacturer’s sizing guide and your tub measurements. The product names alone are not enough to confirm which size will fit. Do not choose based only on the width of your bathroom.
Can I install a conversion kit myself?
The Quick Tub description says the kit includes instructions and is designed for installation without a full remodel, but the work still involves cutting and bonding the tub. Review the installation steps and decide whether you have the right tools and experience. If you are unsure, consult a qualified installer.
Which option is best for a clawfoot tub?
The Pyhomestrim kit is the option in this list designed for adding shower hardware to a clawfoot tub. It does not lower the tub wall, so it will not solve a high-step access issue. Check the rod and support measurements before ordering.
Final Recommendation
For a small bathroom where the main goal is easier tub entry, start with a cut-out kit that matches your existing tub and measurements. The Quick Tub Wide and Narrow offer two size options, while the CleanCut kits add a removable insert for switching between a shower opening and a closed tub. Choose the clawfoot shower kit only when you need shower hardware for a clawfoot tub. Before ordering any option, confirm compatibility and plan for installation and any shower components the kit does not include.
