Looking for a drainage solution but limited by space, digging depth, or retrofitting challenges?
You’re in the right place—we may have just the answer you need!
The Alusthetic Threshold Drainage System offers a fast, simple, and convenient way to manage drainage in entryways and pedestrian areas. Designed with practicality in mind, it comes with adaptable accessories to suit the unique requirements of your project.
We stock the standard 100mm depth option, and for tighter spaces, we also offer a compact 60mm mini depth version—perfect when every millimetre counts.
Advantages of The Shallower Mini Threshold Drains
- Lower profile, less intrusion
Standard Alusthetic drains are about 100 mm deep, while the Mini sits at approximately 60 mm deep—making it much easier to integrate discreetly into level thresholds - Simpler installation in tight spaces
The reduced depth eliminates the need for deep excavation, ideal for retrofits or where floor build-up is limited. - Retains full load rating
The Mini still meets Load Class A15, so it supports standard pedestrian use, wheelchairs, and occasional light loads - Aesthetic discreetness
A slim 65 mm width with aluminium/grated finish remains sleek and unobtrusive—perfect where visual continuity and seamless threshold integration matter. - Easy maintenance
Designed with removable Heel Guard grating—maintenance is as easy as with the deeper models.
Considerations Compared to Standard Depth
| Feature | Mini (60 mm) | Standard (100 mm) |
| Excavation needed | Minimal—great for shallow substrates | Requires deeper trench for full depth |
| Water capacity | Suitable for moderate flows; enough for typical UK doorways | Higher capacity—better where heavy runoff expected |
| Visual impact | Subtle and minimal | More noticeable but still slim |
| Application | Ideal for low-profile thresholds, patios, lightweight access | Better for heavy rain scenarios and slight falls |
For most domestic doorstep applications—especially where height or aesthetics limit depth—the Mini is likely sufficient. If you’re installing across a full-width patio with steep fall or heavy downpours, the standard depth may offer more capacity and resilience.
When to Choose Which depth 100m or 60mm?
- Choose the Mini if you need a slimline solution with minimal excavation, typical domestic usage, and want a sleek aesthetic.
- Choose the Standard (100 mm depth) when dealing with heavy rainfall areas, steeper falls, or if you want extra capacity even when installation depth is not an issue.
Next Steps
- Determine your site conditions – space below threshold, expected water flow.
- Calculate drain length including any corners or T‑junctions.
- Select the drain profile (Mini or Standard) based on aesthetics vs performance trade-offs.

Whether you’re navigating tight installation spaces, installing a retrofit, or simply want a sleek and subtle drainage solution, the Alusthetic Threshold Drainage System—especially the Mini 60mm profile—offers a practical, stylish, and efficient answer. With its shallow depth, durable load rating, and discreet appearance, the Mini is tailor-made for modern domestic entryways and low-profile thresholds.
