Albott Shower Curb Kit, Complete System

The Albott kit combines a 38″ x 60″ tray with an off-center drain, curb, waterproof membrane, corners, bonding flange, trowel, and level. The base uses thickened EPS foam with a PE membrane that provides a preset drainage slope to prevent pan collapse and ensure smooth water flow. Its upgraded waterproof membrane minimizes loose fibers for a cleaner waterproofing layer. An integrated leveling tool helps align pipes and curb positioning for precise installation, reducing field adjustments.
M-D PROVA-Shower Kit 60″ × 60″ (Center Drain)

The PROVA-SHOWER KIT includes a pre-sloped 60″ × 60″ foam pan, a waterproofing membrane, a stainless steel drain grate, curbs, corners, a joint strip, and pipe seal. It is designed for full waterproof tiled installations and can be trimmed to fit smaller spaces. Optional extensions enable larger layouts. The kit uses a polypropylene waterproofing membrane bonded to an EPS foam base, creating a vapor-tight enclosure to prevent long-term water damage.
VEVOR 60″x48″ Shower Pan Kit

This kit uses a high-density HDPE waterproof membrane with a robust EPS board and double-layer 3M adhesive for a reliable barrier. It includes a stainless steel serrated trowel and a 304 stainless steel grid filter for fast drainage. The perimeter curb is an XPS solid design that resists deformation. The included membrane is smooth and non-fuzzy to improve waterproofing performance and simplify tiling work.
VEVOR 72″x72″ Shower Pan Kit

Designed for larger showers, this kit uses a 32mm tray with a high-density HDPE waterproof membrane, double-layer 3M adhesive, and EPS board for a strong barrier. It includes a perimeter curb, a robust drain system, and a complete waterproof assembly. The base remains lightweight and cuttable, enabling precise sizing for expansive shower enclosures while maintaining reliable water control.
VEVOR 36″x36″ Shower Pan Kit

This smaller unit features a 22mm tray with a durable HDPE waterproof membrane and EPS board. Its slim surround supports minimalist bathroom designs and allows installation without a perimeter curb and mortar beds. The kit emphasizes ease of transport and handling, with a focus on reliable waterproof performance in compact shower spaces.
Shower Pitch Kit for Quick Install

The Shower Pitch Kit provides a method to create the proper drainage slope for mortared shower bases. It is designed to fit standard 36″ x 60″ showers with central drainage and offers time-saving pitch accuracy. The system includes float sticks that help set consistent slopes, reducing the need for frequent levelling during installation.
Buying Guide
Key purchase considerations
- Drain layout: Choose a kit that matches your shower’s center or off-center drain configuration. Some kits optimize slope for off-center drains, while others prioritize a center drain.
- Membrane quality: A smooth, fiber-free waterproofing membrane minimizes risks of leaks and helps with tiling adhesion. Look for bonded membranes that resist tearing.
- Base material: Polystyrene foam bases are lightweight and easy to cut, but ensure the foam thickness and density suit your shower size and tile thickness.
- Scalability: If your project may expand, consider a kit with extension options or modular components to accommodate larger layouts.
- Integrated leveling: An included leveling tool or alignment features can save time and improve accuracy during curb and pipe alignment.
- Accessories: Assess included curb types, corners, joint strips, and drainage grates to ensure compatibility with your tile plan and drain placement.
- Installation environment: For high-moisture bathrooms, confirm vapor-tight enclosure capabilities and compatibility with your chosen waterproofing system.
Comparative considerations
- Size flexibility: Larger pans suit spacious showers but require more precise trimming; smaller kits are easier to maneuver but may require extensions for full coverage.
- Weight and transport: Foam-based pans are lighter and easier to handle than solid concrete alternatives, reducing installation stress.
- Installation speed: Kits with pre-sloped designs and complete accessory sets reduce on-site work and potential errors.
- Durability: Look for robust membranes and solid perimeter components that resist deformation over time and under tile loads.
