Here is a checklist of things to consider before installing a shower enclosure.

• There is adjustment for out of true walls.
• The sliding panels and fixed panels interlock when closed to give a water-tight seal.
• Part assemble the shower enclosure if possible and place it on the tray to check it fits correctly.
• Mark the position of the wall channels to make sure the enclosure sits correctly.
• The hanger brackets/rollers on sliding panels provide a smooth gliding action.
• The door handle should have a safe grip in the wet when opening and closing the doors.
• Ensure the wall channels are vertical using a spirit level.
• Seal the joints between the enclosure, tray, wall channels and tray on the outside only using silicone sealant.

Place the pan upside down, preffably on a dust sheet or any cushioned surface, and fit a new wax gasket ring. Now apply a thin bead of caulk all round the base of the pan. Next, you may want somebody to help you guide the pan down into the fixing bolts. Tighten the screws by hand then check if the pan is level with a spirit level. You can now tighten the screws with a wrench or spanner, but be careful not to over-tighten them as the pan may crack.

Now position the cistern over the pan, resting it on the rubber cushion. The small water-intake pipe will need to slot through a hole in the pan, as will the bolts. Once positioned tighten the bolts. Apply the flexible supply pipe and connect the cistern handle to the flapper chain.

Run a bead of sealant between the base of the pan and the floor.

You can now turn the water back on and check for any leaks. If everything is working precisely fix the cistern lid and attach the toilet seat.

If the toilet has been here for a long time you may find that the bolts which fasten it to the floor have become eroded to the state where you cannot unscrew. In this case, take a hacksaw and saw them off.

Underneath the cistern there should be two bolts or screws fastening it to the pan. Unfasten these and remove the cistern. The pan will be sealed to the floor, but with a little force it should come unstuck easily. To stop any unpleasant smells rising up from the sewer pipe, stuff an old cloth in there.

Lastly, check the floor flange to see if it’s damaged at all. if so, replace it.
