TubCore 3N MODX™ SMC Bath Module – 3-Wall Tub Surround with Full Back Panel & Corner Shelves
The TubCore 3N 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 one full-size back wall panel, creating a simple configuration with fewer back-wall joints.
Unlike 4-piece MODX models, the TubCore 3N uses a single full back panel. This helps simplify the wall layout during installation, while the larger package size is better suited for freight or project-based delivery.
With integrated corner shelves and a durable high-gloss finish, TubCore 3N is a practical solution for builders, remodelers, manufactured housing, multifamily projects, and standard alcove bathroom upgrades.
3-Piece Configuration
The 3-piece configuration includes two side wall panels and one full-size back wall panel. It is still a complete three-wall surround system. The main advantage is a cleaner back-wall layout with fewer panel joints, while the trade-off is a larger package size for shipping and handling.

Product Overview
Built with Kostone SMC — a reinforced composite material engineered for strength, water resistance, and long-term durability, MODX™ combines wall panels, bathtub or shower base options, and integrated connection details into a modular bath system. It is ideal for multifamily housing, manufactured housing, hospitality bathrooms, builder projects, remodel programs, and dealer distribution.
Features an interlocking wall design that helps simplify installation, reduce alignment errors, and minimize the need for traditional caulking in key connection areas. Its direct-to-stud installation structure allows the module to be installed efficiently in new construction or renovation projects, helping reduce labor time and improve jobsite consistency.
Available in bathtub and shower configurations, MODX™ can include practical design options such as integrated corner shelves, back-wall niches, above-floor or under-floor drain compatibility, and flexible seat solutions depending on the project requirement.

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.
