Principle

Privacy without doors

At outdoor pools and swimming lakes, doors are often the first victims of vandalism. Our answer is the Schnecke (German for “snail”). You touch nothing when you enter or leave. The cubicle stays open at the top and bottom and cannot be locked. Both make misuse harder. The seamless surface is easy to clean.

The cubicle is quick to set up and can be moved later. The base slab is seamless and lies directly on a compacted gravel bed. The cubicle is made of reinforced concrete and stands on three stainless steel feet. It is weather-resistant and vandal-resistant.

Low-maintenance

There are no hinges, no locks and no timber. The cubicle can stay in place over winter and does not rot.

The Schnecke principle

Form instead of mechanics

Conventional changing cubicles often do not last long in public spaces: latches break, hinges corrode, timber rots. The Schnecke has none of that. It gives privacy through its shape rather than through mechanisms and is made of concrete and stainless steel. The spiral wall leads into a sheltered interior with no moving parts at all. There is a 30 cm gap between the wall and the base slab at the bottom, and the cubicle is open at the top. That keeps the air moving.

One cubicle has room for one person with their clothes and bag. The spiral shape blocks views in, yet from outside you can see whether the cubicle is occupied. The two parts weigh about 1.0 t and 2.3 t and are not bolted together. If needed, the cubicle can be moved to another site with a mobile crane, wheel loader or forklift.

Use

Changing room or shower

The Schnecke is intended for outdoor pools, swimming lakes, lakeside lidos, campsites and sports grounds. It stands free as an outdoor cubicle and is also available as a shower cubicle if wanted. The shower cubicle comes ready-made with a floor drain and shower: the base slab is set over the waste-water pipe, and only the water supply then needs connecting. Alternatively, the cubicle is available with just recesses for a drain and water pipe. Wind, frost and UV radiation do not harm it. The Schnecke does not need constant supervision: it is vandal-resistant and does not burn.

Outdoor pool and swimming lake

The changing cubicle stands free at an outdoor pool or swimming lake. On site, a compacted, frost-proof gravel bed with 5–20 mm grading is enough. The base slab can sit flush with the ground or slightly above it.
