How To Fit a Shower Screen On a Bath

We’re not all blessed with an abundance of space in our bathrooms, hence why over-bath showers have always been a popular space saver.

The resulting conundrum though is how to prevent the water spilling out all over the floor when you’re showering. There are two traditional options: a shower curtain or a bath shower screen. The former is easy and inexpensive to install, but even shower curtains that attest to being “mould and mildew resistant” rarely turn out to be entirely so. Shower screens offer a clean alternative, both in terms of hygiene and aesthetic. Fitting a shower screen properly is essential though, as water is adept at finding the gaps in poorly installed screens and will exploit said gaps as a route to creating unwanted aquatic features on your bathroom floor. In this guide we’ll walk you through how to fit a shower screen on a bath, after a quick look at the different types of shower screen you can choose from.

Types of shower screen

There are several types of bath shower screen. The main options you will encounter are static (fixed screens that don’t move), hinged (screens that swing in and out on hinges to allow access to the bath) and folding (screens that concertina so that you can fold them up flat against the wall when not in use).

Mira’s bath shower screens come in three sizes: mini, single and twin. The mini screen is fixed, the single screens are hinged, while the twin screen has one short fixed panel and a larger hinged panel.

If you’re looking to install a shower enclosure, rather than a bath shower screen, we have a guide on that too.

How to remove an old shower screen

If you’re replacing an existing shower screen, then the first step is to remove the one that’s currently in place. You will usually do this by following these steps:

  1. Remove the glass panel from the metal wall channel.
  2. Use a drill to remove the screws attaching the channel to the wall.
  3. Remove the sealant so that you can take the channel off the wall.


Before fitting your new bath screen, give the wall and the edge of your bath a good clean to remove any residue and dirt that has built up over time.

How to fit a shower screen

Shower screen installation is relatively straightforward, providing you are competent at DIY, especially drilling into tile. Remember that shower screens fittings aren’t designed to be completely watertight so there’s always a chance that some water will escape. Be sure to apply silicone sealant where indicated to reduce the chances of water spillage.

  1. Make sure that the bath is level and that the walls are vertical and square.
  2. Position the wall channel on the wall, using a spirit level make sure that it is upright. Always fit the wall channel to the highest point on the bath side.
  3. Mark the position of the fixing holes, then remove the wall channel.
  4. Drill with a 6mm masonry bit and plug using the wall plugs. For other types of wall structure alternative fixings may be required.
  5. Position the wall channel on the wall and partially install the fixing screws.
  6. Apply silicone sealant according to the manufacturer’s instructions along the length of the wall.
  7. Fully tighten the fixing screws, making sure that the wall channel is upright.
  8. Carefully lift the bath screen into position. Adjust the bath screen until the seal correctly touches the bath, creating a seal to prevent water leaking through.
  9. Drill two 3mm holes in the bath screen frame and through into the wall channel at the bottom and middle positions only, with a 3mm HSS drill. Install the plastic washer and the screw and tighten the screws.
  10. If there is a gap between the edge of the moving panel and the foam seal, push the top corner of the glass until the gap closes.
  11. Drill the remaining 3 mm hole with a 3 mm HSS drill. Install the plastic washer and the screw. Tighten the screw and fit the concealing caps to all three screws.
  12. Make sure that the seal is still correctly positioned on the bath. Remove the rod from inside the seal.
  13. Apply sealant in accordance with the manufacturer’s instructions along the inner surfaces of the bath screen.
  14. Fit the plastic covers to the top of the extrusions.
  15. Allow the silicone sealant to cure for 24 hours before use.
