Tools and Materials for Fitting Shower Wall Panels 

When it comes to installing waterproof shower wall panels, the right tools and materials are essential. Here is what you need to get started:

  • Wet Wall Works’ 2 Panel DIY Shower Kit – This kit includes everything needed for a 2 panel installation, including the panels themselves, trims and sealant.
  • Fine Tooth Hand Saw – This saw is used to cut the panels to size.
  • Measuring Tape – Measure twice and cut once! Make sure you measure accurately before cutting the panels.
  • Pencil – Use this to mark where the cuts need to be made on the panels.
  • Safety Glasses – Always wear safety glasses when cutting the panels or trim to reduce the risk of injury.
  • Silicone Gun – This gun is used to apply sealant and frame the panels once they are installed.
  • Stanley Knife – A sharp knife is necessary for trimming any excess or cut-out sections of the panel.
  • Spirit Level – This tool is used to make sure that the panels are level before sealing them in place.
  • Safety Gloves – Wear gloves when working with sharp tools or materials to protect your hands from any potential cuts and scrapes.

Now that you have all the correct tools and materials, you can begin the installation process.

Pre-Installation Preparation

Pre-Installation Preparation

Pre-Installation Preparation is one of the most important steps in installing waterproof shower wall panels. Before you begin the installation, it is essential to measure the area accurately, prepare the wall and dry-fit the panels.

  • Measuring Accurately – Measure the area to be panelled twice before you begin installation to ensure accuracy. It is crucial to get accurate measurements for everything to fit correctly and look as it should once completed.
  • Preparing the Wall Surface – Prepare the wall surface to ensure it is clean, flat and even. If there are any bumps or uneven patches on the wall, these should be smoothed out before installation begins.
  • Dry Fitting – Dry fitting is essential when installing shower wall panels, as it allows you to check the fit of each panel before applying adhesive and sealant. This will ensure that all the panels fit together correctly and look as they should when finished.

Now that you have everything prepared, you are ready to begin the installation.

Installing Internal Corner Trim

Installing Internal Corner Trim

Installing internal corner trim is an important step in the process of installing waterproof shower wall panels. Here are the steps to follow:

  1. Cut the internal corner trim to the desired panel height using a fine tooth hand saw. Measure and mark the trim first to ensure accuracy.
  2. Place the internal corner trim on a level surface and apply adhesive to the outer edges of the trim.
  3. Position the internal corner trim on the wall and apply pressure to achieve a firm fixing.

Note: Internal trims have an 18mm void; therefore, when fitting panels to an internal corner, the panel will need to be cut accordingly.

Marking and Cutting the Wall Panels

Marking and Cutting the Wall Panels

Marking and cutting the wall panels is another crucial step in the installation process. Follow these steps for a successful installation:

  1. Using a tape measure, measure the top, middle, and bottom of the wall the panel is being fitted to.
  2. Transfer these measurements to the panel by running a pencil line down the non-decorative face of the panel using a pencil and a spirit level.
  3. With a fine tooth saw, carefully cut through the panel following the line marked.
  4. Cut off the tongue or groove to ensure a tight fit when fitting the wall panels into trims.

Installing Wall Panels

Installing wall panels is a straightforward process. Follow these steps:

  1. Apply a good amount of the Wall Panel Adhesive to the wall. I recommend you use 1.5 tubes of adhesive per wall panel.
  2. Fit the wall panel to the wall and apply even pressure to smooth out all air pockets.

Repeat this process for each panel.

Installing End Cap Trim

Installing end cap trim will give a finished look to the installation. Follow these steps:

  1. Measure, mark, and then cut the end cap trim to the desired height of the wall panel using a fine-tooth saw.
  2. Apply adhesive to the back of the trim and fit it into place. The end cap trim should slot directly behind the panels.

Sealing Gaps with Silicone

Sealing gaps with silicone is necessary to prevent water from seeping behind the panels. Follow these steps:

  1. Silicone any gaps around any fixtures or fittings as required.
  2. Leave to dry as per the manufacturer’s instructions.

There you have it-it’s as simple as that! You have now successfully completed the installation process for your waterproof shower wall panels.
