Upgrade from vinyl sheet flooring to Stone Polymer Composite (SPC). SPC, was introduced as an alternative to WPC flooring. SPC has an extruded Calcium Carbonate core with fewer emulsifiers giving it additional density for greater impact resistance. It also resists plank expansion and contraction in extreme temperature swings; this is due to the dense core and  absence of the layer of LV. It can float over most substrates and offers superior resistance to standard household spills and moisture.
