Ross’s Home Discount Centre offers a range of high-quality bathroom tiles and floor tiles. Should you have a question in relation to our tiles, please look for the answer below before getting in touch with us.

  • What are Mosaic Tiles?

    Mosaic tiles are very small tiles, typically less than 100mm square and are most commonly known as splashback tiles due to their popularity as a finish for kitchen and bathroom splashbacks. They are available in many different materials including porcelain, ceramic, glass, natural stone and others. They also come in various finishes.

    Commonly sold pre-mounted on mesh or paper sheets around 300x300mm in size, these sheets can be cut down to generate a pattern when mixed with other tiles. For example a 300x300mm sheet of 50x50mm mosaics could but cut down into narrower strips and joined together end to end to create a feature in a shower wall.

    Key benefits of mosaic tiles include:

    • Mosaics are used generally as feature tiles to enhance a room.
    • They can be used as splashback tiles in kitchens and bathrooms.
    • They are bright and can add character without being over-powering.
    • They can be a bold and dynamic statement reflecting the home owner’s personality.
  • How many extra tiles should I include when ordering tiles?

    It’s advisable to add 10% to the total number of tiles when planning for straight tiling. For diamond pattern, 600mm x 600mm or larger tiles, it’s recommended to add 15%. We also recommend purchasing an extra box or two before the project starts. It can be difficult to match the same tile or batch if you’re going to request it years after the job is complete. This will make the process of replacing tiles a lot easier in the future.

  • How do I calculate how many square metres of tiles do I need?

    For a basic square or rectangular room, you need to measure the length and the width in metres. Then, get the total square meters by multiplying the length by the width. To subtract areas that you don`t want to tile, use the same method to calculate the area and then subtract it from the total area.


  • What is lippage?

    The term “lippage” is an industry-exclusive word for unacceptable height differences between adjacent tiles. Tiles should be set so that the edges are flush with each other. Not only is lippage unacceptable aesthetically but on floors the tiles will be prone to more abrasion at the protruding edges

  • What is the best way to maintain tiles?

    Simply dry sweeping is good for floors to prevent soiling. Occasionally a good cleaning with pH-neutral tile and stone cleaner is recommended for floors and walls.

  • Can you tile over old tiles?

    Yes. If the substrate is stable and the existing tiles are without failures it can be a very practical solution.

  • What is the best way to cut tiles?

    Almost all ceramic and porcelain tiles can be straight cut very precisely and quickly with a manual tile cutter that scores the surface and then splits it. A wet-saw or handheld grinder can be used to do L-shaped cuts and such. Many glass tiles and mosaics can also be cut with a manual score-and-snap tile cutter. Stone tiles need to be cut with a wet-saw or high speed grinder. Ceramic wall tiles are the easiest to cut and drill into. Today’s dense porcelain tiles require more expensive blades and bits to efficiently cut and drill them. Visible cuts in an installation benefit from being sanded with a wet diamond hand pad to soften and smooth the edge.

  • Should I use sanded or non-sanded grout?

    The rule used to be to use non-sanded grout for joints 3mm or less and to use sanded grout for joints bigger than 3mm. However, today there are universal grouts available that are produced with finer sand particles and will work for most joints. These “New Generation” grouts are so fine that they can be used with glass mosaics, wall tiles and many polished stone tiles without scratching the surfaces.

  • What size grout joint should I use?

    The tile type often dictates what size joint space to use. It is desirable to have small joints in most cases. If a tile is rectified a 2 mm or 3 mm space is possible. For many floor tiles a 3 mm, 4 mm or 5 mm joint is good. It often depends on the calibration of the tiles. Unless a tile has been rectified, most tiles are not 100% perfectly sized from one to the next, therefore a bigger joint than 2 mm is required to enable a proper installation. They can sometimes vary in size from tile to tile by a half millimeter or so due to baking and drying factors during production, which is normal.

  • What is an “unglazed and polished porcelain tile”?

    Unglazed porcelain tiles are highly polished and have rectified edges. They are usually through-body porcelain and suitable for commercial traffic. Some of them are treated with an impregnating sealer at the factory whereas others may have a label on the carton that states that a solvent-based impregnator needs to be applied during installation.

  • What is a “lappato or semi-polished porcelain tile”?

    The finish on different semi-polished tiles can vary from a very slight polish on the high spots of a textured glaze to an almost fully polished surface that reveals some pits or dull areas. Often it is done to more authentically duplicate stone tile which have some natural fissures. It is also less slippery and less susceptible to visible scratches than fully polished tiles.

  • What is a “glazed and polished porcelain tile”?

    A polished porcelain tile, usually rectified, is produced by applying a thick glaze, machining it smooth and polishing it. Glazes are necessary for printing broad digital inkjet designs onto the tile. Unglazed porcelain, which can also be highly polished, is not suitable for most digital inkjet designs.
