If you want to make a tub easier to enter and also use it for showering, it’s important to know that these are two different upgrades. The products below include step-through tub inserts or shower hardware, but none is clearly listed as a complete kit with a built-in shower seat. If sitting while you bathe is a must, plan to choose a separate seat that fits your tub and installation.
Our top choice for lowering a tub’s entry is the CleanCut Step Tub Conversion Kit. For adding a shower to a tub that lacks one, the GBBNE kits are more relevant. Compare the options carefully: some change the tub opening, while others add a shower riser and head.

Our Picks: Best Tub To Shower Conversion Kit With Seat reviews
1. CleanCut Step Tub Conversion Kit: Best for a Lower Entry
The CleanCut kit is designed to turn part of an existing tub wall into a step-through opening. It is an accessibility modification, not a shower fixture set: it does not add a shower head, riser, or seat. If your tub already has a shower, or you plan to add one separately, this insert may help reduce the height you need to step over.
The kit includes the insert, support structure, industrial-grade adhesive, waterproof wrap, cutting template, and installation guide. It is designed for most fiberglass, steel, and cast-iron tubs. Because the tub is cut during installation, check the product’s fit guidance and your tub’s material and shape before buying. The supplied information does not give the insert’s exact opening dimensions.
This is a more focused option than the shower-riser kits below: it changes access to the tub rather than adding shower plumbing. It may suit someone who wants to keep the existing tub and reduce its entry barrier. It will not provide a place to sit, and cutting the tub is a significant modification, so consider whether you are comfortable with the installation or want a qualified installer to handle it.
Pros:
- Designed to create a lower step-through entry in an existing tub.
- Includes a cutting template and key installation materials.
- Made for use with most fiberglass, steel, and cast-iron tubs.
- Can avoid replacing the whole bathtub when the tub itself is suitable.
Cons:
- Does not include a shower riser, shower head, or seat.
- Requires cutting into the existing tub, so careful fit checks and installation are essential.
Verdict: Choose the CleanCut kit if your main goal is a lower tub entry and your tub matches the kit’s fit requirements; look elsewhere if you need a seat or shower hardware in the same package.
2. GBBNE Polished Chrome Tub Shower Kit: Best for a Standard Tub
This GBBNE kit is for a bathtub without a built-in shower. It includes a 70-inch shower riser, a swivel shower head, a tub spout with diverter, a wall bracket, mounting hardware, and adapters for 1/2-inch and 3/4-inch tub spouts. The pull-up diverter switches water between the tub spout and shower.
The riser is described as SUS304 stainless steel, with ABS parts, and the listed flow rate is 1.8 gallons per minute. Its wall-mount design and adjustable shower-head angle make it a practical way to add overhead showering without choosing a full tub replacement. Some users report that the included brackets feel stable when secured to the wall and that installation is straightforward, though fit and setup can depend on the tub’s existing connections.
This kit does not lower the tub wall or provide a seat. You’ll need to confirm that your tub spout and plumbing arrangement work with the included adapters, and that the wall can accept the mounting hardware. Compared with the CleanCut and Quick Tub inserts, this addresses shower function rather than tub access.
Pros:
- Includes a tall riser, swivel shower head, tub spout, and mounting hardware.
- Adapters are supplied for two listed tub-spout sizes.
- Pull-up diverter lets you switch between tub and shower flow.
- Polished chrome finish suits a range of bathroom styles.
Cons:
- Does not include a seat or make the tub easier to step into.
- Compatibility depends on your existing spout, plumbing, and wall mounting location.
Verdict: This is a sensible choice when you want to add a shower to a standard tub and have checked the spout and wall-mount requirements.
3. Pyhomestrim Clawfoot Tub Shower Kit: Best for Vintage Clawfoot Tubs
Unlike the wall-mounted GBBNE kits, this Pyhomestrim set is built around a clawfoot tub. The package description lists a bathcock diverter faucet, rectangular shower rod, shower riser, ceiling support rod, wall bracket rods, shower head, and curtain rings. Its traditional layout is intended to create a shower enclosure around a freestanding tub.
The listed shower-rod dimensions are 48 by 27 inches, and the faucet uses 3-3/8-inch centers. The ceiling support can be set to listed lengths of 10, 18, or 28 inches, or cut to a needed length. The product also describes a 1-inch outside diameter for the shower rod and 5/8-inch outside diameter for its ceiling and wall support rods. Measure your room and verify the faucet spacing before ordering; the dimensions matter especially when the tub sits near a window or other obstruction.
This is the most specialized option in the group. It may suit a clawfoot-tub owner who wants a coordinated shower arrangement, but it is not a fit for a typical built-in tub. It also does not provide a seat or a lower-entry opening, so it does not meet those accessibility needs on its own.
Pros:
- Includes a shower rod, riser, faucet, supports, and curtain rings.
- Designed specifically for clawfoot and vintage-style tubs.
- Adjustable support arrangement can help accommodate different room layouts.
- Lists key dimensions shoppers can compare with their tub and bathroom.
Cons:
- Not intended for standard built-in tubs.
- Does not include a seat or a step-through tub insert.
Verdict: Consider this kit if you have a clawfoot tub and its faucet spacing and shower-rod dimensions match your bathroom; skip it for other tub styles.
4. Quick Tub Wide Walk-In Conversion Kit: Best for a Wider Step-Through Insert
The Quick Tub Wide kit is a cut-out insert for an existing bathtub. It is intended to create a step-in opening without replacing the whole tub. The package includes an insert, cutting template, two tubes of industrial-strength adhesive, an angled nozzle, and instructions. The product describes use with steel, fiberglass, or cast-iron tubs and advises measuring carefully before purchase.
The supplied product details list a 12-inch minimum height and a 12-inch seat depth. That “seat depth” specification does not mean the kit includes a separate shower seat; the package contents list an insert and installation supplies. Treat it as a tub-access modification, not a seated shower solution. Some users report that installation was manageable with help from a handyman, but cutting and bonding the tub still call for careful measuring and following the instructions.
The manufacturer also describes pairing the insert with a Quick Tub Cap to switch between a walk-in opening and a full soaking tub; the cap is not listed among this kit’s included components. Compared with the CleanCut product, this option is specifically labeled wide and provides listed height and depth measurements, but you should still use the sizing guide to confirm fit.
Pros:
- Designed to create step-in access while keeping the existing tub.
- Includes a template, adhesive, angled nozzle, and instructions.
- Listed for steel, fiberglass, and cast-iron tubs.
- Provides stated height and seat-depth measurements for fit checks.
Cons:
- Does not include a separate shower seat or shower fixtures.
- Requires cutting into the tub, and the manufacturer stresses measuring first.
Verdict: Choose the Quick Tub Wide kit if you want a step-through opening and its sizing guide confirms a fit; arrange a separate seat if you need to bathe while sitting.
5. GBBNE Matte Black Tub Shower Kit: Best for a Matte Black Finish
This GBBNE kit has much the same function as the polished chrome version, with a matte black finish. It is designed for a tub without a built-in shower and includes a 70-inch stainless-steel riser, shower head, tub spout, wall bracket, and mounting hardware. The listed features also include adapters for 1/2-inch and 3/4-inch tub spouts and a pull-up diverter.
The shower head can swivel for angle adjustment, and the listed flow rate is 1.8 gallons per minute. The product details describe ABS components and a painted black finish. As with the chrome option, this kit adds shower capability but does not lower the tub wall or include a seat. Check the installation details against your plumbing and wall before ordering.
The main reason to pick this version over the polished chrome model is appearance. The functional descriptions are similar, so compare the finish with your other bathroom fixtures and make sure the required tub-spout adapters suit your setup. It is not a substitute for an access insert if stepping over the tub wall is the central concern.
Pros:
- Includes a shower riser, head, tub spout, and wall-mount hardware.
- Has a matte black finish for bathrooms using darker fixtures.
- Offers a swivel shower head and pull-up diverter.
- Adapters are listed for two tub-spout sizes.
Cons:
- Does not include a seat or reduce the tub’s entry height.
- Requires checking your plumbing connections and mounting surface.
Verdict: Pick the matte black GBBNE kit if you need shower hardware for a compatible tub and prefer its finish; choose an access insert separately if you need a lower entry.
How to Choose a Tub-to-Shower Conversion Kit
Decide whether you need easier entry, shower hardware, or both
A step-through insert changes the tub wall to make entry easier. A riser-and-shower-head kit adds showering to a tub that lacks a shower. These products solve different problems, and none of the options here is listed as a complete kit that includes both a conversion insert and a shower seat. Write down what you need before comparing features, and be prepared to buy compatible parts separately.
Check whether the product includes a seat
Do not assume that a tub conversion kit includes a place to sit. The Quick Tub listing gives a “seat depth” measurement, but its included components do not list a separate seat. If seated bathing or showering is important, look for a seat with clear size and installation details, and confirm it is suitable for your tub and intended use. A separate seat should not be treated as a substitute for checking overall bathroom safety.
Measure your tub and check material compatibility
For a cut-out insert, confirm the tub’s material, shape, and dimensions against the manufacturer’s sizing guidance before cutting. CleanCut and Quick Tub describe compatibility with several common tub materials, but fit can still depend on the tub’s specific design. For a shower kit, measure the tub spout connection and the available wall space for mounting.
Match the kit to your tub style
Standard built-in tubs and clawfoot tubs need different hardware. The GBBNE kits are described for standard bathtub layouts, while the Pyhomestrim set is designed for clawfoot tubs and lists a particular faucet-center measurement and shower-rod dimensions. Check those measurements against your setup rather than relying on the product name alone.
Consider installation before you buy
Shower-riser kits include mounting hardware, but you still need to confirm that the connections and wall mounting work in your bathroom. Cut-out kits require modifying the tub, applying adhesive, and following the installation instructions. If you are unsure about cutting, plumbing, or securing supports, ask a qualified professional to assess the job before you begin.
Compare included parts, not just the product title
Read the included-components list closely. The GBBNE kits include shower components, while the CleanCut and Quick Tub kits focus on tub access. The Pyhomestrim set includes a broader collection of clawfoot shower parts. A “conversion kit” can mean very different things, so make sure the package covers the specific parts you need.
Frequently Asked Questions
Does any option here include a shower seat?
No separate shower seat is listed in the supplied product details for any of these five options. The Quick Tub listing includes a 12-inch “seat depth” measurement, but that should not be mistaken for an included seat. Check package contents and plan separately if you need seating.
What is the difference between a step-through insert and a tub shower kit?
A step-through insert modifies the tub wall to create a lower opening. A tub shower kit adds shower hardware, such as a riser, shower head, and diverter. One addresses access; the other adds shower function.
Can I use a step-through insert with a tub that already has a shower?
The CleanCut and Quick Tub products are described as tub cut-out or step-through conversion kits, not shower fixtures. They may be relevant if you want to lower the tub entry while keeping existing shower hardware, but confirm the product’s sizing and installation guidance for your specific tub.
Will the GBBNE shower kit fit any bathtub?
The product is described for standard bathtub layouts and includes adapters for 1/2-inch and 3/4-inch tub spouts. That does not guarantee compatibility with every tub or plumbing arrangement. Check your spout, mounting location, and product instructions first.
Is the Pyhomestrim kit suitable for a standard built-in tub?
It is described as a clawfoot-tub shower kit, with a rectangular shower rod and bathcock diverter faucet. Its dimensions and setup are intended for clawfoot and vintage-style tubs, so it is not the general-purpose choice for a standard built-in tub.
Can I keep using the tub as a full bathtub after adding a cut-out insert?
The Quick Tub listing describes a separate Quick Tub Cap that can be paired with the insert to switch between a walk-in opening and a full soaking tub. The cap is not listed as included with the conversion kit. Check the manufacturer’s details for compatibility and what must be purchased separately.
Which option should I choose if accessibility is my main concern?
For a lower entry, compare the CleanCut and Quick Tub inserts and confirm which one fits your tub. If you also need a seat, that will require a separate, compatible product. If you are unsure whether an insert or seat will work safely in your bathroom, seek qualified guidance before making changes.
Final Recommendation
For reducing the step into a compatible existing tub, the CleanCut Step Tub Conversion Kit is the clearest fit in this group. The Quick Tub Wide kit is another option when its stated measurements and sizing guidance match your tub. If your main goal is adding a shower, choose between the GBBNE kits based on finish, or consider the Pyhomestrim set for a clawfoot tub. None is presented as a complete tub-to-shower kit with a seat, so verify that any separate seating solution fits your needs and your tub before buying.
