This is not a good situation.
To grout or not to grout luxury vinyl tile.
My questions are on the use of luxury vinyl tile lvt flooring my wife would prefer to go with either the lvt or a high end single sheet product that is tough and will hold up to water.
In some areas you can get away without having grout but the tiles will be more susceptible to damage because grout or something adds strength to the floor and keeps the tiles in place.
You will be able to grout immediately after the vinyl tile floor installation with no waiting for thinset mortar to dry.
Some brands of luxury vinyl tile will use glue or grout while others lock together or have peel off backing.
A groutable vinyl tile is just half the thickness and because the vinyl tile has rounded edges there s even less space for the material to work itself in between.
Your bath foyer laundry room or other area that can t afford much down time will be out of commission for a considerably shorter period than is the case with other types of tile.
Whichever brand of luxury vinyl tile you use you can have peace of mind that with it comes the ease of installation.
I would suggest if you are spending the money and taking the time to install a vinyl floor the luxury vinyl tile the grout is your best option for a long lasting result.
My wife hates ceramic tile due to mold issues here in the south eastern us and generally not liking the grout which requires frequent cleaning and resealing.
