There are a few things to consider when installing wood look tile without grout. The first is the type of tile you are using. If you are using porcelain or ceramic tile, then it is possible to install the tile without grout. However, if you are using natural stone tile, then it is not recommended to install the tile without grout. The second thing to consider is the size of the tiles you are using. If the tiles are small, then it is possible to install them without grout. However, if the tiles are large, then it is not recommended to install them without grout. The third thing to consider is the type of installation you are doing. If you are doing a dry lay installation (meaning that you do not use any adhesive or mortar), then it is possible to install the tile without grout. However, if you are doing a wet lay installation (meaning that you use adhesive or mortar), then it is not recommended to install the tile without grout.
