How Do You Replace A Bathtub With A Walk In Shower: A Comprehensive Guide in 2023

The bathtub has been a staple in American bathrooms for over a century. But as homes have gotten smaller and lifestyles have gotten busier, the need for a more efficient showering solution has become apparent. The walk-in shower is quickly becoming the new standard in American bathrooms. But if you’re thinking of ditching your bathtub in favor of a walk-in shower, there are a few things you should know first. In this blog post, we will explore how to replace a bathtub with a walk-in shower, from start to finish.

Decide if you want a one-piece shower unit or pre-fabricated shower kit

If you’re planning on replacing your bathtub with a walk-in shower, you’ll need to decide if you want a one-piece shower unit or pre-fabricated shower kit. One-piece units are made of solid, waterproof materials and have fewer seams, making them more durable and easier to clean. Pre-fabricated kits come in a variety of colors and styles and can be customized to fit your space.

Choose the right size and shape for your bathroom

When you are planning to replace your bathtub with a walk in shower, one of the most important decisions you will make is choosing the right size and shape for your bathroom. There are many different factors to consider when making this decision, and it is important to take your time to ensure that you make the best choice for your space.

One of the first things you need to think about is how much space you have available in your bathroom. If you have a small bathroom, you may want to choose a smaller shower unit so that it doesn’t overwhelm the space. On the other hand, if you have a large bathroom, you can afford to go bigger with your shower unit.

Another important factor to consider is the shape of your bathroom. If you have a square or rectangular shaped bathroom, then you will likely want to choose a shower unit that is also square or rectangular in shape. However, if you have an oddly shaped bathroom, then you may need to get creative with your shower unit selection in order to make it fit well.

Finally, you need to think about what features you want in your shower unit. Do you want a simple shower with just a basic door, or do you want something more luxurious with multiple shower heads and body jets? Once again, take into account the size of your bathroom when making this decision so that your new shower unit fits well and doesn’t look out of place.

Remove your old bathtub

It’s time to replace your old bathtub and install a new walk-in shower. But before you start your project, you first need to remove your old bathtub. This can be a challenging and dangerous task, so it’s important to follow these steps carefully.

First, turn off the water supply to your bathroom. Then, open the drain to release any remaining water in the tub. Next, remove any caulk or sealant around the edge of the tub.

Now it’s time to start removing the actual tub. If your tub is cast iron or steel, you will need to use a sledgehammer and chisel to break it up into smaller pieces. For other types of tubs, you may be able to simply pull it out from its framing.

Once the tub is out, you’ll need to clean up any debris and dispose of it properly. Then, you can start installing your new walk-in shower!

Install the new walk in shower

If you’re ready to install a new walk in shower, there are a few things you’ll need to do to prepare. First, make sure you have the right tools for the job. You’ll need a hammer, screwdriver, drill, and saw. Next, remove the old bathtub. This will require disconnecting the plumbing and removing the tub from its platform. Once the tub is out, you can begin installing the new shower. Start by putting up any walls or partitions that are needed. Then, install the shower base and connecting it to the plumbing. Finally, add your desired fixtures and finishings.

Add finishing touches to your new shower

Your new shower is almost complete! Here are a few final steps to make sure it is perfect:

1. Add caulking around the edges of the shower base and walls. This will help seal the shower and prevent leaks.

2. Install the shower head and hand held shower hose, if desired.

3. Attach the grab bars, if needed, for safety.

4. Add a shower curtain or door to contain the water spray.

5.Turn on the water supply and test the shower to make sure everything is working properly.


If you’re looking to replace your bathtub with a walk-in shower, there are a few things you need to keep in mind. First, you’ll need to make sure the new shower will fit in the space where your old bathtub was. You’ll also need to ensure that your drainage system can handle the increased water flow from a shower. Finally, you’ll want to consider what type of doors or curtains you’ll use to enclose your new shower. With a little planning, replacing your bathtub with a walk-in shower can be a relatively easy project that will give you years of enjoyment.
