  • 1 Measure the base of the shower and buy a door to fit the existing shower tray. In this case we are installing a corner entry shower door. There are generally two standard sizes of shower tray – 760mm and 800mm.
  • 2 Assemble the components of the shower door frame according to the manufacturer’s instructions.
  • 3 Sit the assembled frame on to the shower tray. Mark with a pencil where the track should go. This will act as a guide for the U channel.
  • 4 Once the position is marked remove the shower frame.
  • 5 Then place the U channel in line with the mark. Using a spirit level to ensure it is vertically level. Mark the drill holes for the U channel on to the wall.
  • 6 Run a multi-purpose detector over where you will be drilling to ensure there are no hazards behind the wall. Top Tip: Be extra thorough when looking for pipes and cables, as there are a lot of pipes and cables behind the walls in a bathroom.
  • 7 Put masking tape on your markings and drill holes using a tile drill bit. The tile drill bit has a special tip for precision drilling into tile. Remember safety first – always wear safety goggles when drilling. Top Tip: Let the drill do the work. Hold the drill perpendicular to the tile and apply a bit of pressure. Go slow until you break the surface of the tile. Once you are through the surface you can increase the speed of the drill
  • 8 Insert suitable rawl plugs into the hole, ideally past the depth of the tile.
  • 9 Run a bead of sealant at the back of the U channel and secure it into place by inserting the screws.
  • 10 Repeat on the other side.
  • 11 Offer up the frame against the wall and slot it into the U channels and ensure the frame is level.
  • 12 Then drill pilot holes through the guide holes and secure it in place with screws.
  • 13 Fit the door to the frame as per manufacturer’s instructions. Read instructions carefully to determine the correct method for putting on seals, hinges/rollers, or any fittings such as handles
  • 14 Once the shower door is in place, seal with an appropriate sealant and leave for 24hrs. It would be preferable to use a Bath and Shower Sealant with Mould Resistance
