You want to attach a soap tray to your shower wall. If it can be positioned in an area where little water falls, attach it with some heavy double-sided adhesive strip (see Adhesive tapes and your hardware merchant). If you have to drill some holes, here's how it's done.
Before you start Be aware that fine dust from drilling a coloured tile can fall on surrounding grout and stain it. Therefore begin by making a disposable tray out of cardboard and attaching it with masking tape below where you intend to drill. OR get someone to hold a vacuum-cleaner nozzle next to your drill tip.
If there is masonry behind the tile, you will need to buy a wall anchor that will fit the screw supplied with the soap holder. (See also install or remove wall anchors.) Use a masonry or tile drill bit. Only the tip of a masonry bit does the drilling. Select a bit that will fit the anchor then drill through the tile and into the masonry (See how to drill the tile below). If there is wood or panelboard behind the tile, the screw will need to pass through the hole in the tile but then go into a smaller hole in the wood underneath. In this case, you will drill the tile first. (Measure the screw against the tip of the bit so that the bit's tip is equal to, or only slightly wider than the screw's thread. Drill the hole in the tile (see below), then measure the screw against another smaller bit before drilling into the wood behind the tile (see selecting a bit to fit the screw). How to drill the tile Mark where you want to drill the holes using a felt-tip pen or chinagraph pencil.
Ceramic tiles are glazed hard so it is impossible to get a drill bit to stay exactly on your pen mark unless you first make a dimple hole for it to be guided by. Do this by turning a drill bit on the spot by hand. This will leave a small depression. Professionals use a hand-held spiral boring tool for this purpose. Do not use a hammer with any tool or you will crack the tile! ALTERNATIVELY, if you don't have a boring tool, stick a couple of pieces of clear adhesive tape over the hole. This will hold the drill in place just long enough for it to cut into the glaze.
Use a power drill on low speed, or even use a hand drill if you have one.
If the drill bit does wander slightly when you drill another hole don't try to drill again next to it. File the screw hole in the bracket you want to attach to an oval. The head of the screw will probably cover up the slight error!
If you are using a wall anchor, insert it in the hole and screw the bracket onto the tile. If you are using only a screw, screw the bracket straight on.
DON'T tighten the screws too tightly or you might crack the tile.
How to replace a cracked or broken wall tile
Before you remove anything, purchase a replacement tile that is the same as, or will blend in with, the other tiles on the wall. Make sure it is no thicker than the existing tiles or it will sit proud of the others when you attach it. Also buy some tile adhesive and some tile grout of the same colour as the rest.
Put on safety glasses to protect your eyes from glassy shards. Using the largest masonry bit you own, drill a hole in the middle of the tile to be removed (see, how to drill a hole through a tile, above). Place a nail punch at an angle in the hole then gently hammer the punch until the tile cracks open. Using a coal chisel or large screwdriver tap the broken pieces out (picture top right).
Now you have to get rid of the old adhesive and grout that was behind and around the tile. Gently chisel it away. If you have trouble with the adhesive, try heating the chisel or an old paint scraper to melt and scrape it out. Don't be tempted to apply heat from a blow torch or hair dryer as you might damage the surrounding tiles.
Using the notched spatula that comes with the tile adhesive (or make a notched scraper out of strong cardboard using pinking shears), spread some adhesive in the hole. Be careful not to put more in than is under the surrounding tiles or your new tile will sit proud of the others.
Place the tile in the hole (picture below right). Use pieces of cardboard or matchsticks to keep the tile central in the hole with equal slots on each side for the grout. Wipe away any excess adhesive (see the adhesive directions for clean up). Once tidy, allow the adhesive to set.
After about 12 hours apply some grout in the slots around the tiles. Wipe away any excess with a moist sponge. Gemtly polish, when drying, with a dry cloth.
