You might get your tiles from the good DIY store but check local newspapers for tile warehouse in your area – they'll have more on the screen and can offer you a good discount. You should be able to take your adhesive, grout and tools from the same retailer.
You need a shovel 6mm for wall and 10mm for the floor. 4mm for mosaics. You need an adhesive ready for the wall. You need two empty buckets, a large sponge, grout/squeegee buoys, paddles for mixing powder, tape measure, spirit levels, cheap tile cutters: a diamond wet cutter and cutter may be dry, and scraper.
Check how much this will cost and seriously consider whether it is worth buying: most tilers will only charge a few hundred for an average bathroom or kitchen and then you will not have a tool that roams afterwards. If you a novice, it is vital that you consider hiring a professional for your tiling. You can also get excellent wall and floor tiling in Perth from Gun Tiling.
However, if you trying to accomplish this job by yourself, the important thing is to measure carefully, using your spirit level to get a horizontal line, first set your pattern and order far more tiles than you think you need! I started on the lines remaining in and around the edge of the tub or from the focal point such as under the lid stove in the kitchen or around the windows.
For the floor, check to see patterns that will allow you the most complete tiling. Consider preparing a dilute PVA on the wet surface area. It is worth looking at the tiles around the commercial stores and your friend's house first to see what you like and dislike. Where the tiles are cut? What stands out? Set one line at a time and then build a wall or across the floor back to the door.
Spread adhesive with a trowel and drag horizontally to store excess pressure. Place the tiles carefully but not too hard. Use matches to place your tiles. Try the brick design to save the hassle of aligning the joint! Leave overnight before installing grouting.
