Tub-to-Shower Conversion: A Decision Guide
Convert a tub to a shower when the tub is unused, when stepping over the wall has become difficult, or when the shower in the room is too small to be comfortable. Keep the tub if it is the only one in the home and bathing still matters to your household. The technical decisions — drain position, threshold height and waterproofing system — follow from that choice.

A shower waterproofing system creates a continuous water barrier behind and beneath the tile, and it matters more to long-term performance than the tile itself. Common approaches include sheet membranes, liquid-applied membranes and waterproof foam-board panel systems, each compatible with specific setting materials. The right choice depends on the substrate, the shape of the shower, and the setting materials being used, and it should be decided before tile selection.
