Tiling in a house can be a great way to enhance the appearance and functionality of different rooms. However, tiling requires careful planning and preparation to achieve a professional finish. Here are some steps to follow when tiling a floor:

- Clean the floor surface thoroughly and make sure it is flat and dry.
- Measure the floor area and find the center point of each wall. Snap chalk lines across the center points to create a grid on the floor.
- Lay out some tiles along the chalk lines to see how they fit. Adjust the layout if needed to avoid cutting small pieces of tiles at the edges.
- Mix the adhesive or mortar according to the manufacturer's instructions and spread it evenly on a small section of the floor using a notched trowel.
- Place the tiles on the adhesive and press them firmly. Use tile spacers to maintain consistent gaps between the tiles.
- Cut the tiles that need to fit around the edges or obstacles using a tile cutter or a wet saw.
- Let the adhesive dry completely before removing the spacers and applying grout to the joints with a grout float.
- Wipe off any excess grout with a damp sponge and let it cure for at least 24 hours.
- Apply silicone sealant around the perimeter of the floor and any other areas that need to be waterproofed.

Tiling in a house can be a rewarding DIY project if you follow these steps and use quality materials and tools.
