Tub-to-shower conversion kits can make a bathroom renovation easier and more affordable, simplifying switching out a tub for a new shower. There are several reasons to get rid of an old tub and install a shower instead. Showers can free up bathroom space and they tend to use less water, so they’re more energy efficient.
They’re safer to use since there’s no tall edge or climbing in and out, which means they’re more suitable for those with mobility concerns. Converting a tub into a walk-in shower is a big project, but it’s well worth it for many households.
To convert a tub into a shower, there are a few options ranging from add-ons to an existing tub, to luxurious walk-in showers and shower stalls. Replacing a tub with a shower kit is one of the most cost-effective and straightforward ways to replace a tub with a shower.
We chose the DreamLine Shower Base and Backwall Kit as our best overall pick because of its modern design, versatile installation options, and durable acrylic and ABS plastic construction. However, all our selected products were vetted for effectiveness and reliability.

Before You Buy a Tub-to-Shower Conversion Kit
There are essentially two options when switching out a tub with a shower: tiling a new shower or installing a shower enclosure kit, which is essentially a premade, ready-to-install shower enclosure. Installing a shower kit is often cheaper and easier than tiling a new shower, and the best shower kits on our list can look just as stylish as a tiled option. Choosing the best shower surrounds for a bathroom comes down to budget and preferred finished look.
When removing a bathtub, especially an old tub, there’s always the possibility of finding damage beneath. Since a new shower should last upward of a decade before the need to repair or update, it’s important to make sure the foundation it’s built on will last at least that amount of time as well.
Once the bathtub is pulled out, make sure to check the condition of the floor and subfloor, framing, and the existing plumbing. Look for signs of water damage and repair as needed. Repair any areas of subfloor or studs that might have been damaged in the removal process. It’s also a good idea to update the plumbing fixtures as part of the project to lower the chance of leaks in the future.
How We Chose the Best Tub-to-Shower Conversion Kits
With the amount of time and money that goes into converting a tub to a shower, it’s vital to choose the right shower kit. Since every bathroom remodel costs a certain amount and requires different things, we chose a range of tub-to-shower conversion products, from products that can retrofit an existing tub to different styles of walk-in tub-to-shower kits.
Regardless of the product type, we looked for a few key features. We chose kits with high-quality materials that we believe will hold up for the decade-plus that a new shower should last. Through reading product specs and shopper reviews, we prioritized products that are easy to install so DIYers can tackle the job, at least in part. Lastly, a shower is a main piece of the bathroom, so we also considered style, choosing tub shower conversion kits that look attractive.

What to Consider When Choosing a Tub-to-Shower Conversion Kit
The best shower enclosures look beautiful and are easy to install, making it possible to convert tubs to showers on a budget. The best tub-to-shower conversion kits often include the wall panels and shower pan (though sometimes the pan is sold separately), and can include a shower door as well. When shopping for a tub-to-shower conversion kit, consider the shower’s size, shape and location, floor, installation process, and materials.
Size
Size is one of the most important aspects to consider when choosing between the best showers for a bathroom renovation. The new shower needs to fit the space, so make sure to measure carefully.
Many standard alcove and drop-in tubs measure around 60 inches wide by 30 or 32 inches deep. When it comes to a shower, the National Kitchen & Bath Association recommends a minimum interior shower size of 36 inches wide by 36 inches deep. Small prefabricated showers can measure as little as 32 inches wide by 32 inches deep, and can go up in increments up to around 60 inches wide by 36 inches deep. It’s not too difficult to find shower kits to fit in an old tub space, though sometimes there might be a need to alter wall or flooring finishes to gain an extra few inches of width. Choose a shower the same footprint size as the bathtub for an easier renovation.
Corner tubs measure around 60 inches wide by 60 inches deep, so there is usually more than enough space to replace these large tubs with a stall or step-in shower. If installing a swinging shower door, make sure to account for clearance space.
Shape and Location
Some of the most common bathtub types include alcove, drop-in, and corner bathtubs. The bathtub shape and location can determine the ideal shower kit, although it’s often possible to work around these factors with more renovation work. There are many shower stalls or walk-in showers that can fit into alcove or drop-in tub spaces. Corner shower kits are also common, making it fairly straightforward to replace a corner bathtub. Whether the shower is installed in the previous tub location or elsewhere in the bathroom, the plumbing fixtures and drain location may need to be modified.
The best tub-to-shower conversion kits can come in one piece or in several pieces to assemble on-site. While the best one-piece shower stall options are appealing, larger ones might not fit through the bathroom door. In this case, a multipiece shower kit is the right choice.
Floor
Another consideration is the shower floor. Many of the best tub-to-shower conversion kits include a shower pan, often with a curb. As the name suggests, these have a raised curb and an appropriate slope to keep water contained and direct it down the drain.
Curbless showers are the other option. Since these don’t have a raised curb, they require a bit more renovation work. The bathroom flooring often needs to be altered to create a drainage slope and allow the shower pan to sit flush with the floor. While these pans are more difficult to install, curbless showers are more accessible and can make the bathroom look more open. Regardless of the shower floor type, look for a textured surface to help prevent slips and improve safety.
Installation and Hardware
Shower kits come in alcove, corner, and freestanding options and can have rectangular, square, round, or angled configurations. Choose a design depending on the installation location and preferred look.
Installing one of the best shower inserts is much simpler than tiling a new shower, but that doesn’t mean it’s an easy task. When converting a tub to a shower, drain and water connections will likely need to be moved. Many shower kits have a center drain instead of a drain on one end (common for bathtubs). It might also be necessary to add a shower head or raise the height of the existing shower head to accommodate the new shower height.
Many homeowners call in professional installation experts to deal with these aspects, especially since some municipalities may require a permit and inspection to modify plumbing locations.
Materials
Shower kits are usually made of acrylic, fiberglass, or composite materials. These materials are lightweight and durable, but each comes with its own pros and cons. Acrylic showers tend to be pricier than fiberglass showers, but they also tend to be more durable and last longer since the material is more scratch-, puncture-, and stain-resistant. Fiberglass is more susceptible to damage, including scratches and discoloration.
Fiberglass showers have a couple of benefits as well; they tend to be more affordable and easier to repair than acrylic showers. Some showers have a fiberglass or mixed-material base with an acrylic finish that helps bring some of the benefits of this material. Other options are composites made to look like other materials, such as composite stone.
FAQs
Converting a tub to a shower is a major bathroom renovation project, but it’s one that will pay off for those wanting to take on this task. Whether with the help of professionals or as a DIY project, renovating with the best shower stalls and kits make the job easier. Still wondering if a shower kit is the right choice for your project?

Switching a tub for a shower is a multistep (and often multiday) process. You’ll need tools like a pry bar, hammer, or oscillating multi-tool to demolish the existing tub and surrounds. Remember to have the necessary eye and ear protection to do the job safely. Once the old tub is removed, basic plumbing and repair materials will likely be needed to fix any damage and set up the plumbing for the new shower. To install a new shower kit, you’ll need the tools and materials specified by the manufacturer for installation.

It’s almost always cheaper to buy and install a shower kit. Tiling a new shower is a pricey and lengthy process. While tiled showers are beautiful and worth the installation cost for many homeowners, those on a strict budget will find that a shower kit is often the economical choice.
Yes, experienced DIYers can try to install a shower kit without professional help. It does take a wide range of know-how though, and only those comfortable with demolishing the old tub, updating the plumbing, and installing the shower kit should take on the job. Otherwise, hire a professional.
Prices for bathtub to shower conversion range depending on the size, material, design, and accessories. Expect to pay between $400 for basic shower kits and up to $2,000 for more luxurious options.
