How To Convert A Tub To A Walk In Shower: Options and Considerations in 2023

The average bathroomtub is only used for bathing, and is often an eyesore in an otherwise beautiful bathroom. If you’re looking for a way to modernize your bathroom and make it more practical, why not convert your tub into a walk-in shower? It’s a project that you can do yourself, and it doesn’t require any major construction. In this blog post, we’ll show you how to convert a tub to a walk-in shower step by step. With just a few simple changes, you can have a sleek and stylish shower that is much more functional than a tub.

Step One: Determine If Your Tub Can Be Converted

Converting a tub to a walk-in shower is a great way to update your bathroom and make it more accessible. But before you start tearing out your tub, there are a few things you need to consider.

First, you need to determine if your tub can be converted. Some tubs are simply too small or the wrong shape to be converted into a shower. If your tub is made of fiberglass or acrylic, it may not be possible to convert it.

If you have a traditional porcelain or cast-iron tub, however, conversion is usually possible. You’ll just need to make sure that the drain and supply lines are properly positioned for the new shower configuration.

Once you’ve determined that your tub can be converted, the next step is to decide what type of shower enclosure you want. There are many different styles of showers on the market, so take some time to browse and find one that will fit your needs and budget.

Step Two: Choose A Shower Base

When you are ready to install your new shower, the first step is to choose a shower base. There are many different types of bases available on the market, so it is important to do your research and select the one that best fits your needs.

If you have a small bathroom, you may want to consider a corner shower base. These types of bases fit snugly into the corner of the room and can save valuable space. If you have a larger bathroom, you may want to opt for a square or rectangular shower base. These provide more space for showering and can give the illusion of a larger bathroom.

Once you have selected your shower base, it is time to install it. This process will vary depending on the type of base you have chosen. Always follow the manufacturer’s instructions for installation to ensure proper set up.

Step Three: Select Your Surround

After you have decided on the style and materials for your new walk in shower, it’s time to select your surround. The surround is the wall or walls that will enclose your shower. There are many different types of surrounds available, so it’s important to choose one that will complement the style of your new shower and fit well within your budget.

Some common types of surrounds include:

-Tiles: Tiles are a popular choice for walk in showers because they are easy to clean and maintain. They come in a wide variety of colors, sizes, and styles, so you can find a tile that fits the aesthetic of your new shower perfectly. Plus, tiles are water resistant, which is ideal for a wet area like a shower.

-Stone: Stone surrounds give your walk in shower a luxurious look and feel. They are durable and easy to clean, but they can be pricey. If you love the look of stone but don’t want to spend too much money, consider using faux stone panels instead.

-Glass: Glass surrounds provide an open and airy feel to your walk in shower. They let light into the space and make it appear larger than it actually is. Glass surrounds can be made from clear or frosted glass, so you can choose the level of privacy you want.

Step Four: Install Your Shower Base

If you’re installing a new shower, you’ll need to start by installing the base. There are many different types of shower bases available, so consult with a professional or do your research to find the best one for your needs. Once you’ve selected a base, follow the manufacturer’s instructions for installation. In most cases, you’ll need to secure the base to the studs in your wall using screws and brackets.

Once the base is installed, it’s time to install the drain. Most shower drains come with easy-to-follow instructions. Simply connect the drain to your home’s plumbing and secure it in place according to the manufacturer’s directions.

With the drain installed, you can now add waterproofing around the perimeter of the shower base. This will help prevent water damage to your bathroom walls and floors. Apply a generous bead of caulk or sealant around the edge of the shower base, making sure to fill any gaps or cracks. Then, apply a strip of waterproof tape over the top of the caulking or sealant. Allow everything to dry completely before proceeding to step five.

Step Five: Attach Your Surround to the Base

After your surround is level, dry fit it to the base. Apply a continuous bead of 100% silicone caulk around the entire perimeter where the surround will meet the base. With a helper, lift the surround and set it in place on the base. Use construction adhesive at the corners and along any seams in the base. Center the drain opening over the drain hole in the base and trace around it with a pencil. Cut out the traced circle with a jigsaw fitted with a fine-tooth blade.

Step Six: Caulk and Seal

After the final coat of mortar has dried, it’s time to caulk and seal the tub-to-shower conversion. First, apply a continuous bead of silicone caulk along the joint where the tub and shower base meet. Then, use a wet finger to smooth out the caulk.

Next, apply a generous bead of caulk around the drain opening. Again, use a wet finger to smooth out the caulk. Finally, apply a bead of caulk along the edge where the shower base meets the wall. Once again, use a wet finger to smooth out the caulking.

Allow all of the caulking to cure for at least 24 hours before using the shower.

Step Seven: Add Accessories

After you have put in the new shower base and tiled the surround, it is time to add the finishing touches. These include adding trim around the edges of the shower, as well as any accessories you want.

Trim can be added to both the top and bottom of the shower surround. This will help to give it a polished look, as well as protect any exposed tile edges. You can use either plastic or metal trim, depending on your preference.

As for accessories, there are a few different options you can choose from. One is to add a shower curtain, which can provide both privacy and style. Another option is to install a glass door, which will give your bathroom an upscale look. Finally, you may also want to consider adding shelves or a seat within your shower space.


Converting a tub to a walk in shower is not as difficult as it may seem. With a few tools and some basic knowledge, you can easily do it yourself.
