  1. 1

    Remove the shower head and knob for turning on and off the water. Break down any current tiling. Typically a shower will have three walls of tiling. These must be broken off using a hammer.

  2. 2

    Remove the plasterboard. In most cases, the plasterboard will be worn and deteriorating from water leakage. You can remove them using a drill to unscrew the screws across the board.

  3. 3

    Remove the shower tray or base that was used previously. Carve through all the sealant that was used around the shower. Once it is removed, notice the piping in the floor. This is where the water will drain into. If there is cracking or rust, replace it with a new waste pipe and joint. When placing the new shower tray, match the drainage hole to the piping.

  4. 4

    Mix a small amount of cement and place the cement over the area that the tray will be placed. Before the cement dries, place the shower tray upon it. Level it with the level tool. Place caulking and waterproof coating around the base of the shower tray.

  5. 5

    Insert new plasterboard. The plasterboard should be 1/2-inch thick. Take measurements of the walls. Then insert two to three sheets of plasterboard for each of the smaller walls and four to six for the larger wall. Measure the size of the holes you need for the piping.

  6. 6

    Screw the plasterboard onto each wall. Match up the holes with the piping for the on/off knobs and the hole for the actual shower head. Use caulking or tile adhesive to put over the screws in the plasterboard and lines between each board.

  7. 7

    Paint the plasterboard with acrylic primer. Trowel over all of the holes, lines and joints with Bal WP1 wWaterproof coating. Once the coating dries, sand over the boards lightly to make sure there is no excess adhesive or caulking. Wipe grout over the walls to help the tiles stick.

  8. 8

    Place the tiles evenly on the plasterboard. Do one wall at a time. Place shower fixture and handle onto the piping by turning the attachment clockwise onto the pipe.

  9. 9

    Fit in the shower enclosure. The kind of closure you bought will determine what you need to fit it into the shower unit to prevent water from getting on the bathroom floor.

Tips and warnings

  • Place grout on the wall you are working on and finish with the tile before placing grout on another wall.
