How to tile a niche effectively and efficiently?

To tile a niche effectively and efficiently, start by measuring the area and selecting the right size and type of tiles. Prepare the niche by cleaning and priming the surface. Apply thin-set mortar to the niche and press the tiles into place, making sure they are level and evenly spaced. Use tile spacers to maintain consistent grout lines. Allow the mortar to dry before grouting the tiles. Seal the grout to protect it from moisture and stains.
