TubFlex 4N-A MODX™ SMC Bath Module – 3-Wall Tub Surround with Split Back Panel & Shelves
The TubFlex 4N-A MODX™ Bath Module is a complete three-wall alcove tub surround system designed for fast, clean, and repeatable installation. Built from durable Kostone SMC, this model includes two side wall panels and a split back wall (upper and lower sections) for parcel-friendly shipping, making it easier to handle and deliver for project-based installations.
With integrated corner shelves and a durable high-gloss finish, TubFlex 4N-A provides a practical, low-maintenance solution for builders, remodelers, manufactured housing, multifamily projects, and standard alcove bathroom upgrades.
4-Piece Configuration
The 4-piece configuration includes two side wall panels and a split back wall. Once installed, the upper and lower back panels combine to form a complete back wall.

FAQs
Please read to find out more.
What is Kostone SMC?
All Kostone products are crafted from SMC (Sheet Molding Compound) composite. Stronger and more durable than traditional acrylic, with excellent water resistance to ensure long-term performance in wet areas.
What is MODX Bath Module?
MODX Bath Module is Kostone’s modular SMC bath system designed for faster installation, easier handling, and scalable bathroom project delivery. It is available in bathtub surround and shower surround configurations.
Is MODX Bath Module designed for alcove installation?
Yes. MODX Bath Module is designed for standard three-wall alcove bathroom applications.
What is the difference between 3-piece and 4-piece MODX systems?
Both 3-piece and 4-piece MODX systems are complete three-wall alcove surround systems. The difference is the back wall panel configuration.
A 3-piece model includes two side wall panels and one full-size back wall panel. This creates fewer back-wall joints, but the package is larger and is typically better suited for freight or project-based delivery.
A 4-piece model includes two side wall panels and a split back wall made from upper and lower sections. During installation, the two back wall sections are assembled together to form one complete back wall. Because the back wall is split into two smaller panels, the overall package size is reduced, making the system easier to handle and suitable for parcel-friendly shipping.
How long does MODX take to install?
MODX is designed for fast installation. It would take about 2-3 hours, compared with 1–3 days for tile installation.
