How to fit a shower screen on a bath

Follow our instructions to properly install a bath shower screen

Blog
Thursday 31st December 2020

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. It’s essential to install your shower screen properly 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.  

If you’re carrying out a full bathroom renovation, we recommend hiring a professional installer to ensure the job is done well. However, with the correct tools and some DIY knowledge, you shouldn’t have any problems fitting a bath screen yourself.  

Mira Bath Shower Screen

Different types of bath 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.

How to fit a shower screen over your bath 

Fitting a bath screen 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. 

Tools you’ll need 

  • Electric drill 
  • Screwdriver  
  • Spirit level 
  • Silicon sealant gun 
  • Tape measure 
  • Pencil 

You’ll also need 

  • Screws 
  • Screw caps 
  • Seal
  • Wall channels 
  • Wall plugs 

These are usually all supplied with the shower screen. 

Step-by-step guide to fitting a bath screen 

  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 to 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 3mm 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.
