How to Choose the Right Shower Base: Materials, Installation, and Waterproof Design
A concise, practical guide for homeowners, contractors and OEM buyers - compare materials, drainage layouts, installation methods and maintenance tips to select the best shower base for your project.

What is a Shower Base and Why It Matters
A shower base, also called a shower pan or shower tray, is the pre-formed foundation that collects and channels water to the drain. A well-designed base prevents leaks, improves drainage efficiency and extends the lifetime of the bathroom installation.
Common Materials and How They Differ
Material choice affects weight, finish, durability and cost. Below is a quick comparison to help you decide according to project type and budget.
| Material | Strength & Durability | Weight | Slip Resistance / Finish | Typical Use |
|---|---|---|---|---|
| Acrylic | Moderate; flexible | Light | Textured options available | Residential upgrades, easy install |
| Fiberglass | Moderate; lower cost | Light | Standard textured finishes | Budget & bulk projects |
| Stone Resin | High; rigid & long-lasting | Heavy | Premium textured options; matte finish | High-end residential, hotels |
| Stainless Steel | Very high; commercial-grade | Medium to heavy | Often slip-treated | Commercial & institutional |
Tip: For OEM or custom projects, stone resin offers the best balance of durability and visual quality but requires stronger subfloor support during installation.

Drainage Design and Waterproof Structure
Drain location (center vs side) should match your plumbing plan. Look for a raised lip or flange that integrates with wall waterproofing to minimize leak risk. Multi-layer designs (waterproof membrane + structural support layer) improve long-term performance
Installation Methods & Floor Requirements
Surface-mounted (Floor-mounted)
Fast and compatible with most existing bathrooms. Typically installed on a level subfloor and sealed to the wall and drain.
Recessed (Flush) Installation
Creates a seamless, modern look flush with the finished floor. Requires precise floor preparation and professional waterproofing.
Ensure the subfloor is level and solid.
Align the drain precisely and test for water flow during installation.
Use compatible sealants and follow the manufacturer's waterproofing instructions.

How to Select the Right Shower Base

1
Measure your bathroom and confirm the drain position before ordering.
Choose material by intended use: acrylic/fiberglass for cost-efficiency; stone resin for premium builds.
2
Check anti-slip ratings or textured finishes for safety-important for families and commercial areas.
Request test reports: load testing, water-tightness and surface wear tests for supplier verification.
3
Consider OEM/ODM customization if you need special drain positions or non-standard sizes.
FAQ
- Q1: Are "shower base" and "shower pan" the same?
- A: Yes - the terms are commonly used interchangeably. Some markets prefer one term over the other.
- Q2: Which material is more durable-acrylic or stone resin?
- A: Stone resin is generally stronger and more rigid. Acrylic is lighter and easier to install but less impact-resistant over the long term.
- Q3: Can the drain position be customized?
- A: Yes, many manufacturers offer OEM/ODM options to customize drain location and size to suit project needs.
- Q4: How do I know if a shower base is non-slip?
- A: Look for textured surface options and slip-resistance test reports or ratings. Anti-slip textures and matte finishes improve safety.
- Q5: Do shower bases need regular maintenance?
- A: Routine cleaning with mild, non-abrasive cleaners is sufficient. Avoid strong solvents and abrasive pads that can damage the surface coating.
