Toilet Y4
The Rheinstrom Yacht-WC Y4 is the classic among the yacht toilets. The large-sized hand pump and a large, smooth-surface pump foot guarantee unmatched quality. The pump and valve body are made of gunmetal and coated with Rilsan. The screws, the piston rod and the valve stem are made of stainless-steel. Optionally, the Y4 is also available without a coating. The model Y4 is made of seawater resistant materials. In the uncoated model, the Y4 is the ideal yacht toilet for restored classic boats. It is suitable for large sailing and motor yachts, cargo and passenger ships and fishing boats.
