Need a drainage solution but worried about limited space, digging depth, or retrofitting into an existing doorway or patio? The Alusthetic threshold drainage system is designed to solve exactly that problem—fast, simple, and stylish.
Now with two depth options—Standard (100 mm) and Mini (60 mm)—there’s a drain for every threshold, from compact domestic entrances to larger patios that see heavier flows.
Mini vs Standard – At a Glance
Feature | Mini (60 mm) | Standard (100 mm) |
Excavation needed | Minimal – great for shallow substrates | Requires deeper trench |
Water capacity | Suitable for moderate flows at doorways | Higher capacity for heavy rainfall |
Visual impact | Slim, subtle, unobtrusive | Still slim, but more noticeable |
Best for | Low-profile thresholds, patios, domestic use | Larger patios, heavy rain areas, steeper falls |
Why Choose the Mini (60 mm) Threshold Drain?
Lower profile, less intrusion
At just 60 mm deep, the Mini is perfect when floor build-up or excavation depth is limited.
Easier installation
Minimal digging makes it quick to install in retrofits or where space is tight.
No compromise on strength
Despite its slim size, the Mini still meets Load Class A15, supporting pedestrians, wheelchairs, and light garden use.
Sleek and discreet
With a 65 mm slimline width and aluminium grating, the Mini integrates neatly into thresholds and patios without dominating the look.
Easy to maintain
Removable heel guard grating ensures maintenance is as straightforward as the deeper models.
