Upgrade your bathroom with this 48 in x 32 in linear drain shower base designed for bathroom remodel, renovation, and new construction projects. The carrara white finish provides a clean, modern appearance that complements a wide range of bathroom styles and shower layouts. This threshold shower base features a linear drain with a reversible drain location, allowing left or right drain installation for different alcove shower layouts. Removable aluminum flanges allow zero-threshold, single-threshold, or double-threshold installation configurations, providing flexibility for different bathroom layouts and installation requirements. The pre-sloped shower pan helps direct water toward the drain, improving drainage performance and helping reduce standing water. This design helps simplify installation and supports reliable drainage performance. Constructed from acrylic reinforced with fiberglass, this shower base offers a lightweight yet durable structure that is crack-resistant and easy to clean. The base is compatible with standard 2 in shower drains (drain assembly not included). Installation: Install on top of the finished floor. The base can be installed directly on a level and solid floor, or installed using mortar or thin-set depending on installation requirements. A water test is recommended before final installation to ensure proper drainage. With a 3.5 in threshold height and a 48 in x 32 in footprint, this alcove shower base is suitable for bathroom remodel, renovation, and residential shower installation projects.
