A wash platform--back splash wall drainage gap G improves drainage, cleanliness and efficiency, along with rearward tilted station floor angles .beta..sub.floor and wash platform angles .beta..sub.platform, which improve drainage and animal-groomer stance. Gangable animal bathing stations are disclosed that share common walls and effluent processing for passage to a central waste filtration and treatment means.
