Portable dacha shower with foot membrane pump

Foot-powered shower

It is intended for dacha and garden cabins and can also be used in field conditions. The design was approved by everyone who used it for several years.

A typical dacha shower is usually a booth on a frame of four posts with a water tank on top. Because of its weight, such a fixed structure must be very sturdy — a light frame cannot support a full tank. Filling the tank without running water is also quite difficult, especially for elderly people.

The shower described here avoids those drawbacks. It does not require a dedicated structure and can be set up anywhere. Water is fed simply from a bucket or jerrycan using a membrane pump. The bucket only needs to be placed slightly above the pump, for example on a stool.

Portable shower
Portable shower:
1 — galvanized basin; 2 — pump; 3 — bracket (2 pcs.); 4 — upright (2 pcs.); 5 — bucket; 6 — suction hose; 7 — guy wire (2 pcs.); 8 — curtain (around the perimeter); 9 — ring curtain holder; 10 — shower head; 11 — shower head bracket; 12 — pressure hose; 13 — drain pipe

The pump is operated with the foot. Water enters it from the bucket by siphon action — by gravity. The shower spray can be stopped at any moment and resumed as needed, since you do not have to run water while soaping.

The light shower frame is mounted on a large galvanized steel basin. Two brackets are screwed to its sides; two uprights made of duralumin tubes fit into them. On the uprights is a ring holder for a film enclosure (a gymnastic hoop can be used). Two ordinary bathroom curtains with built-in clip hangers serve as the enclosure. The lower edge of the film hangs into the basin.

Pump
Pump:
1 — body (steel); 2 — valve plate (steel); 3 — cover plate (steel); 4 — fitting (brass); 5 — bushing (steel); 6 — gasket (rubber); 7 — valve (rubber); 8 — washer (rubber); 9 — “piston” (ball); 10 — winding (nylon cord)

A grate of wooden slats is laid on the basin bottom. The pump is placed on it and connected with medical hose to the shower head on an end bracket.

At these dimensions the shower occupies about 1 m². Because the curtains shield the bather on all sides, drafts are not a problem; inside, a microclimate forms determined by the temperature of the falling water. So the shower can be placed anywhere, and spray does not escape past the curtains. After washing, it can be taken apart — the basin can be used for laundry or other chores, the uprights stored in a corner, the curtains rolled up, and the ring hung on a nail in the shed.

One or two buckets of warm water are enough for a proper wash. When the season ends, this dacha shower is also handy in a city flat with all amenities — when hot water is cut off. It can be used to wash a car as well, by fitting an appropriate brush on the hose end.
