We are purchasing a new home from IPAC and considering using the standard white tiles for the showers in the secondary bathrooms. Our concern is too many grout lines (since the tiles are not big) will be difficult to keep clean. We could use bigger tiles to reduce the number of grout lines but that upgrade option is not cheap. We would appreciate hearing other people?s experiences in keeping the grout lines clean and advise on whether it would be better to get the bigger tiles and less grout lines. Thanks.
