The bathroom is different from other rooms in the house because there are fixtures in the bathroom that are semi-permanent. To do the job properly, toilet, handbasin, and bathtubs should be removed. Of course, it is possible to install this item, but the finished product will not look good. Spend a little extra time to remove your bathroom equipment if you want quality work.
But remember, that water needs to be turned off so you may need a plumber. All old floor coverings must be completely removed. Any excess adhesive or cement should be removed completely. You can, however, make this task easier and quicker by just hiring a professional tiler to do the job. You can check out their services online and ask for a price quote.
Though, if you are considering a DIY tile installation then don't cut corners because you will suffer later. If you are not familiar with the process and have no experience in bathroom tiling, it is recommended to call a skilled tiler instead. However, after the bathroom is clean, decide what pattern you want to follow.
Put loose tiles on the floor and take time to fix this part, remember, you have to see this for a very long time.
Now measure the walls and mark the midpoints on each wall. Where you have made the mark in the middle point, tap the small nails into each wall about 1 inch above the floor.
Now it's time to mix your adhesive. These generally come in powder form so follow the instructions on the package to mix properly. Buy good quality adhesives and make sure that it is moisture resistant. This is where you put your first tile. When you learn how to install a bathroom floor you don't have to install tiles in only one direction, but you should install tiles on two walls by alternatively installing tiles.
