How to do it

When tiling a bathroom floor it is always better to remove the sanitary ware. In some cases you may have to tile around sanitary ware but this is not advised as it can really create more work for you in the long run.

  • 1 Remove Sanitary Ware. To remove the sanitary wear turn off the water from the hotpress and leave taps running in the hand basin until the water stops. Flush the cistern to empty the water.
  • 2 Put on disposable gloves. Remove screws from the toilet bowl (usually found at the bottom of the toilet base).
  • 3 Remove wing nuts (found at base of cistern which connects to the bowl).
  • 4 Remove screws from inside the cistern where it secures to the wall.
  • 5 Put down towels or dust sheet for any excess water. Use a sponge or cloth to soak up remaining pooling water in cistern.
  • 6 Disconnect water pipe from cistern by removing coupling nut at the base or side of the cistern.
  • 7 Remove the cistern from the wall and place into bath or shower area you need to do this before you remove the bowl, to prevent it from falling, use a dust cloth in the bath to protect the porcelain.
  • 8 Remove the bowl by gently rocking and when loose tilt towards you to prevent any excess water from spilling out, once again place into the bath or shower area.
  • 9 Cover the outlet pipe with a plastic bag.
  • 10 To remove the sink basin unscrew any nuts or screws from the underside of the basin and connecting water pipes. Before you can start tiling you need to also remove the skirting boards. Remove any screws or nails which may be left in the wall or in the skirting.
  • 11 Remove the waste trap (S bend) from basin. Follow by removing the basin from the wall and place into bath/shower area. Then remove the pedestal.
  • 12 Also remove the bath panel by unscrewing the two screws.
  • 13 Remove any old floor covering.
  • 14 Tile a floor Never tile directly onto floorboards, always use marine plywoods in a bathroom and flexible adhesive to give you a solid base. When screwing down plywood always make sure that your centres are no more than 150mm apart. Make sure the screw is no larger than 25mm on a 6mm plywood.
  • 15 Line out the tiles on the floor you will be tiling. Arrange the tiles on the floor in a cross shape + , this helps to find the balance in the room. Measure the tiles in this position and mark where you will need to cut. Mark the measurement for the cuts on the floor as you go, this will help you work out what cuts you need and where you are placing them later.
  • 16 Open your bag of floor adhesive and mix with water in a bucket (Read instructions for quantities needed on manufacturer’s packaging). Top Tip: If working on plywood use flexible adhesive to allow for floor movement beneath the tiles. If tiling on a masonry floor you can use a standard adhesive. Always read manufacturer’s instructions. Top tip: When cutting tiles, set the blade of the tile cutter right on the marked line. Press the blade down, and push it forward across the tile in one smooth, steady motion to score a line. Press the handle down firmly on either side of the cut and the tile should snap cleanly in two.
  • 17 Cut tiles to size from your earlier measurements earlier in preparation for laying them using a tile cutter. Always put your dust mask and goggles on before cutting tiles with angle grinder.
  • 18 Take extra care when cutting around pipes. Trim off less than you need. Offer up the tile to the pipe and then trim off any extra. Place tile in position before you apply adhesive to the floor, to make sure the fit is correct.
  • 19 Use an angle grinder to trim those awkward areas. Top Tip: There is a difference between a floor tiling trowel and a wall tiling trowel. A floor tiling trowel has a large notch which allows for more adhesion to be spread. A wall tiling trowel has a smaller notch which reduces the amount of adhesive spread.
  • 20 Spread your adhesive on the plywood floor with the notched trowel. Work in sections of half metre square to ensure that the adhesive will still be wet when you get to tiling over it.
  • 21 Always remember to work towards the door beginning with your first tile in the left hand corner and then work across the row. Use sliding movements to get the tile into position.
  • 22 Press spacers into the joints as you tile across. Build the tiles in a grid pattern, in the same direction as your first row.
  • 23 Spread more adhesive on the floor as you work. Go slow and steady and make sure your tiles are level and in line as you move across the room. Use a damp sponge to remove any excess adhesive from the tiles. Leave the tiles to dry for the time indicated in the adhesive instructions.
  • 24 When the floor is completely tiled, it will need to be grouted. Remember, on a timber floor, use a flexible grout. To mix the grout use clean water, a clean bucket and a mixing drill. Always follow manufacturers instructions.
  • 25 Remove any protruding spacers where possible between the tiles and use a grout float to fill the gaps with tile grout. To apply the grout, don’t overload the trowel. Try to get it just in the joint and not on the tile. Tease the grout into the joint to avoid airbubbles.
  • 26 Top Tip: For corners in the room, use mastic around the bath/shower area as this seals the tiles from any water spills, etc. Use washing up liquid on your finger to leave a smooth finish.
  • 27 Remove any excess grout with a damp sponge and leave to dry. For a finer finish you can point the grout by going over the grout lines using a grout finishing tool. Polish off the tiles with a clean dry cloth.
  • 28 Once the grout is dry you can replace your sanitary ware back into position in your bathroom. Place your pedestal back into position. Now check that your basin is also in the right position and check connections.
  • 29 Once you are happy with the positions, mark them and remove the sink and pedestal.
  • 30 Now drill your new holes using a 6mm or 8mm tile bit. Once you have completed the drilling secure rawl plugs into the holes using a hand screwdriver. Using a hand screwdrive will prevent cracking. Then replace the pedestal and basin and screw into position. Reconnect your water pipes.
  • 31 Now replace your toilet bowl and cistern. When it is in the correct position. Mark your drill holes. Then drill holes using a 6 or 8mm tile drill bit. Fix the rawl plugs into the holes and replace the toilet bowl and cistern into its position.
  • 32 Tighten all screws and nuts and reconnect the water pipe. And don’t forget to turn your water back on.
