How to Choose the Right Shower Tray Size
2026-03-28
Introduction
Choosing the correct shower tray size is one of the most critical steps in any bathroom renovation or construction project. A tray that is too small can make showering uncomfortable, while one that is too large can disrupt the flow of the bathroom.
As a leading shower tray manufacturer with 25 years of experience, DAYA has supplied over 80,000 pieces annually to 60 countries. In this guide, we will walk you through how to choose the perfect shower tray size for your project.
Step 1: Measure Your Bathroom Space Accurately
Before looking at specific sizes, you must understand your available space:
- Measure the footprint: Measure the length and width of the floor area where the shower will go. Always measure twice to be accurate.
- Account for wall finishes: Remember that tiles or wall panels (like DAYA's stone resin wall panels) will add thickness to your walls. Measure from the finished wall surface, or calculate the thickness of future tiles.
- Check clearances: Ensure there is enough space for the shower enclosure doors to open fully without hitting the vanity, toilet, or bathroom door.
Step 2: Understand Standard Shower Tray Dimensions
Shower trays come in various standard sizes to fit common bathroom layouts:
- Small Bathrooms (700mm - 800mm): Compact square trays (e.g., 70x70 cm or 80x80 cm) are ideal for en-suites or small guest bathrooms.
- Medium Bathrooms (900mm - 1000mm): A 900x900 cm square or quadrant tray is the most popular standard size, offering a great balance between comfort and space-saving.
- Large Bathrooms (1200mm - 2000mm+): For spacious walk-in showers, rectangular shower bases are the top choice. For instance, DAYA's Series F Rectangular Shower Base offers lengths from 70cm up to 200cm, providing a luxurious, expansive showering area.

Step 3: Choose the Right Shape
The shape of the tray directly impacts the size you can fit into your bathroom:
- Rectangular: Best for replacing bathtubs or creating large walk-in showers.
- Square: Versatile and fits perfectly into corners.
- Quadrant (Curved): Excellent for maximizing floor space in small bathrooms, as the curved front removes the sharp corner.

Step 4: Pay Attention to the Drain Position
When selecting a size, don't forget the plumbing. Does the drain hole on the new tray align with your existing plumbing? DAYA offers shower trays with various drain positions and provides compatible high-flow drainers (like DY-11, DY-16) with a flow rate of up to 25.8 L/min to prevent water pooling.
The Advantage of Custom & Cuttable Shower Trays
What if your bathroom has an awkward layout, an obstructing pillar, or non-standard dimensions?
This is where Stone Resin Shower Trays shine. Unlike ceramic or acrylic, premium stone resin trays from DAYA are cuttable. They can be trimmed on-site during installation to fit perfectly around obstacles or irregular walls.
Furthermore, if you are a distributor or project contractor, DAYA offers robust OEM/ODM services. We can manufacture made-to-measure shower trays with low MOQs (18pcs for one size) to meet the exact specifications of your hotel or residential project.
Conclusion
Getting the shower tray size right ensures a leak-free, comfortable, and visually appealing bathroom. Whether you need a standard 90x90 cm tray or a massive 200x100 cm cuttable stone resin base, DAYA has you covered.
