Keep bathroom tiles or place LVP

[Anthony Kono]

Hi all. Property Class B, currently has Terracotta/ Saltillo square floor tiles throughout the entire  house including both bathrooms.  The tiles have thick 1/4 in grout lines and don’t look too appealing. I will be placing LVP , but should I keep this tile in the bathrooms or place LVP over it ? Replacing the tile with a different tile will be extra labor cost so want to avoid that.  I always thought tile in bathrooms Worked best due to moisture.
