Clean hard water stains from the tile as soon as you notice them, before they become severe. Combine baking soda with water to make a paste. Coat the spots with the paste then sprinkle vinegar onto it until it begins to bubble and foam. Scrub the paste lightly to remove the softened spots, rinse and wipe dry. Alternatively, use a hard water remover specifically formulated for ceramic tile. Do not use highly abrasive cleaners or scrubbing pads on ceramic tile. Abrasives cause permanent etching on the tile surface.
The space between the tiles should be uniform. Use spacers if your tiles don't come on mesh sheets. The larger the tile the larger the space should be between them. Some do_it_yourselfers will make the mistake of pushing tiles too close together to reduce grout lines. Without enough surface area, grout won't bond well and can fail prematurely, leaving room for leaks and water damage. It's also very important to let the adhesive cure fully.
