There are three methods for fitting panels into the corner of shower cubicles:
- Use a corner trim supplied by the manufacturers of the panel
- Butt-joint the panels in the corner and seal with a good quality silicone
- Score the back of the panel and bend the panel 90 deg to form the corner
Most fitters tend to use option 2 as it is the quickest, easiest and neatest method - providing you cut reasonably accurately.
If you are concerned about water ingress you can dry fit the panels first, then run a thick bead of silicone into the corner and then push the first panel into the wet silicone, embedding the corner of the panel in sealant. Run another bead of silicone down the corner and push the second panel into the wet silicone to form the corner. Wipe off any excess on the front of the panel and run thin bead of silicone down the newly formed corner to completely seal it off.
This method is ideal for patterned panels such as mosaic or tile effect panels as corner trims tend to break up the pattern.
This method can be used where there is a shower over the bath or in shower cubicles.
