Replacement Shower. The Ciencia solid-surface shower is primarily designed as a replacement for an outdated bathtub. The base, which features an integral trench drain (with removable cover), installs directly over the subfloor. The walls glue on to the existing surface — whether it’s drywall, plaster, or tile. The shower comes in a variety of sizes, with four color options and five tile patterns. Prices for the complete kit range from $1,875 to $2,650.
