WoodBRIDGE 48″ x 36″ Solid Surface Shower Base
Brand: WOODBRIDGE. Features include a 48″ L x 36″ W x 4-1/8″ H solid surface with a right drain and a three-sided flange design. The surface material resists stains and is non-porous for easier cleaning. Best for alcove installations where a durable, low-maintenance base is needed. Choose this if you want a seamless, leak-resistant installation and a simpler grout-free edge. Caution: This is a shower base, not a full tub; ensure you need a base pan rather than a standalone bathtub.
DeerValley 48″L X 36″W Shower Base
Brand: DeerValley. Features include a non-slip, sloped floor for efficient drainage, reinforced acrylic with fiberglass, and a center drain location. Best for buyers prioritizing safety and stable support in a compact shower base. Better for bathrooms where a central drain location is preferred. Caution: Confirm alignment with the chosen alcove surround, as some surrounds assume a different flange arrangement.
KPUY 48” X 36” Shower Base Pan
Brand: KPUY. Features include a reversible drain and a non-integrated flange design. Best for homeowners who need flexible drain placement to accommodate existing plumbing. Choose this if you require left- or right-side drain options and a lower-profile threshold. Caution: The base height is around 4 inches with the flange; verify clearance with surrounding walls or tiles.
Fine Fixtures Bathtub 48″ x 32″ (Closest 48×36 Option)
Brand: Fine Fixtures. This drop-in white soaking tub uses durable fiberglass-acrylic construction and features a slip-resistant interior. Best for compact spaces where a 48×36 opening is slightly limited but 48×32 can fit with minor adjustments. Choose this if you need a compact tub for smaller bathrooms. Limitation: It is not a 36-inch-wide variant, so confirm opening measurements before purchase.
Voltaire 48″ x 32″ Right-Hand Drain Alcove Bathtub
Brand: Swiss Madison. Features include a built-in apron for easy installation and a right-hand drain. Fiberglass reinforced acrylic adds durability. Best for buyers who want a quick alcove install with an integrated front panel. Choose this if you need a right-hand drain in a compact 48×32 footprint. Caution: This model is 32 inches wide, not 36 inches; verify opening compatibility.
Voltaire 48″ x 32″ Left-Hand Drain Alcove Bathtub
Brand: Swiss Madison. Features include a built-in apron and left-hand drain with fiberglass reinforced acrylic for resilience. Best for left-handed drain configurations in small alcove spaces. Choose this if the plumbing layout favors a left-side drain. Caution: The 32-inch width may require a custom surround for a 48×36 opening.
