That tiling task was not as bad as I thought it would be. First, I had many sleepless nights worrying about it and did a lot of planning.. I used a 120cm x 90cm shower former and 60cm x 30cm porcelain tiles. Please note, they are all multiple of 30 which I think helps when tiling the shower former.
1. Work out where to place your tiles to get the most pleasing end result, laying them on the floor as accurately as possible and making sure you would not end up with very small pieces of cut tile along the edge. Below, you can see what I was trying to achieve. I wanted the tiles to run along the floor and up the wall like a “road”, so I had to ensure the tiles would also look nice around the window.
2. When, you are happy with the location of the tiles, cut the tiles to fit the space available. Please note how the tile line runs right across the centre of the drain. I also made sure that the drain was roughly in the middle of a whole tile (again, to avoid having very small pieces of cut tiles).
3. Work out where roughly you want your slope lines to be. The shower former is virtually flat so you have a bit a room deciding where you want your lines. I wanted the slope to extend more into the room so I made one of the lines longer. Whatever you do, make sure that the slope tilts sufficiently for the water to drain away.
4. Before drawing the cutting lines, lay your tiles down as accurately as possible using the plastic spacers (I used 3mm spacers). Starting with the drain, I left one tile out so I could see the drain underneath. My other tile was positioned exactly across the centre of the drain (it does not look perfectly in the middle in my picture, this is only an optical illusion!), I was able to draw a mirror image of the drain onto my tile. Then, I drew the slope lines on that same side.
4. Place the missing tile over the drain and draw the other half of the drain like a mirror image. Make sure you number every single piece of tile as they will become like a puzzle when cut.
5. Cut your tiles, lay them down again to make sure that they all fit nicely (I did it about three times!). Now is the time to check slopes. I like to write “comments” on tiles like “+A” or “++A” to remind me that I will need to put a bit more adhesive on that specific place.
6. Once you have checked that all tiles would correctly slope towards the drain, you can start laying them with adhesive, making sure you have waterproofed your floor to protect from water damage. There is plenty of information on tanking so I won’t go into details.
7. Before mixing your adhesive, make sure that you have all tools at hand and your tiles are arranged in the order you would feel more comfortable with.
Knee pads or a piece of foam to protect your knees. A suction cup in case you need to remove a tile with minimal disruption. A bucket with a large sponge and clean water. And most importantly, the solution to your puzzle.
I drew my “tiling map” onto the polystyrene tile guide to know exactly which tile goes where so that my piece of paper would not be in the way or worse, would get lost!
