If the hearth ends against a wall, you can use a tile cutter as you normally would. However, if the edge of your hearth ends with no surface pressing against it,you may want to look into rounded tiles. These give a smooth edge to your hearth and make sure cut edges aren’t visible. You can also see if the tile you have has pieces that have been glazed or rounded on one edge. You’d then cut the tile and place it normally, with the cut edge facing inward. 

Yes, tiling a bathroom is a great way to boost your home's value, especially if you are replacing old or dated flooring. Adding a new tile floor can deliver a return on investment (ROI) of around 56.4%, with some projects offering up to 100% ROI. Buyers appreciate new tile because it provides a modern look and is known for being durable, water-resistant, low-maintenance, and easy to clean. For the best results and highest return, consider hiring a professional, as tiling mistakes can be very noticeable and detract from the value.

The tile spacing you should use will depend on the tile and where you’re installing it. Choosing the right tile spacers to maintain a consistent gap between your tiles is tricky. Generally, tile spacing shouldn’t be less than 2 millimeters on walls and 3 millimeters on floors because of stress relief requirements. Getting it wrong can result in uneven tiles and early repairs.

Tile installation can be expensive because it requires more time and labor to install than many other materials. For example, laminate flooring can click and lock into place, and carpet comes in large rolls that you can secure to the floor. On the other hand, tiles need to be cut, laid individually, grouted, and left to cure.
