Step 1: Preparing The Bathroom Space
When it comes to installing a shower from scratch, the first step is to prepare the bathroom space. This includes measuring the available space accurately, assessing the plumbing and electrical requirements, as well as removing any existing shower fixtures or enclosures.
Measuring the available space accurately
Before you begin the installation process, it’s important to measure the available space in your bathroom accurately. This will ensure that the shower you choose fits perfectly in the designated area. You can use a measuring tape to measure the length, width, and height of the space. Record these measurements carefully and make note of any obstacles or irregularities that may affect the installation process.
Assessing the plumbing and electrical requirements
Assessing the plumbing and electrical requirements is another crucial step in preparing the bathroom space for a new shower installation. This involves checking the existing plumbing and electrical connections to ensure they meet the necessary requirements for the chosen shower. If any adjustments or upgrades are needed, it’s essential to address them before moving forward with the installation process. Hiring a professional plumber or electrician can help ensure the job is done correctly and in compliance with building codes.
Removing any existing shower fixtures or enclosures
Before you can install a new shower from scratch, it’s important to remove any existing shower fixtures or enclosures that may be in place. This can include removing the showerhead, faucets, shower doors, or any other components that are no longer needed or compatible with the new shower design. Take care when removing these fixtures to avoid causing damage to the surrounding walls or flooring. If you’re unsure how to safely remove these items, it’s recommended to seek professional assistance.

Step 2: Choosing The Perfect Shower Components
Now that you have a clear vision of your dream shower, it’s time to move on to the important task of choosing the perfect shower components. In this step, we will focus on three key aspects: selecting the ideal shower base or pan, picking the right shower walls or tiles, and deciding on the appropriate shower fixtures and accessories.
Selecting the ideal shower base or pan
When it comes to the foundation of your shower, you want to make sure you choose the right base or pan. The shower base not only provides a level surface for your shower, but it also helps with proper water drainage. Here are some considerations to keep in mind:
- Material: Shower bases can be made from various materials, such as acrylic, fiberglass, or tileable options. Consider your preferences and budget when making this choice.
- Size and shape: Measure your available space and determine whether a square, rectangular, or corner-shaped shower base would fit best.
- Accessibility: If you have mobility concerns or plan to age in place, consider a low-profile or curbless shower base for easy access.
Picking the right shower walls or tiles
Once you have selected the shower base, it’s time to think about the walls or tiles that will surround your shower. The appearance and functionality of these components can greatly enhance your overall shower experience. Consider the following:
- Material: Shower walls or tiles can be made from different materials, including ceramic, porcelain, glass, or natural stone. Each material offers its unique aesthetic and maintenance requirements.
- Design and pattern: Think about the style you want to achieve with your shower. Consider incorporating accent tiles or creating a mosaic design to add a personal touch.
- Maintenance and durability: Choose a material that is easy to clean and resistant to water, mold, and mildew, ensuring your shower walls or tiles maintain their beauty over time.
Deciding on the appropriate shower fixtures and accessories
The final step in choosing the perfect shower components is selecting the right fixtures and accessories that will elevate your showering experience. Here are some factors to consider:

By following these steps, you can significantly reduce the risk of water leakage and ensure a durable shower that will stand the test of time.
Installing the Shower Walls or Tiling for a Sturdy and Aesthetic Finish
Now that the base is complete, it’s time to install the shower walls or tile them for a sturdy and aesthetic finish. Here’s what you need to do:
1. Measure and cut the shower wall panels or tiles according to the dimensions of your shower area. Make sure to account for any fixtures such as showerheads and faucets.
2. Apply an adhesive or mortar to the back of each panel or tile, ensuring full coverage.
3. Start from the bottom and work your way up, applying the panels or tiles in a straight line. Use spacers to maintain an even gap between each piece.
4. Once all the panels or tiles are in place, use a spirit level to check if they are plumb and level. Make any necessary adjustments before the adhesive or mortar dries.
5. Allow the adhesive or mortar to dry completely as per the manufacturer’s instructions.
6. Finally, grout the gaps between the panels or tiles using a grout float. Make sure to remove any excess grout and smooth out the surface.
By following these steps, you can achieve both a sturdy shower and a visually pleasing finish that complements your bathroom’s aesthetics.
With the shower base and walls built and secured properly, you are now one step closer to completing your shower installation project. In the next step, we will focus on installing the shower fixtures and accessories to make your shower fully functional.

Step 5: Installing The Shower Fixtures And Accessories
