The Story
The Qtoo Wall-Mounted Washbasin System by d line is a built-in sink tap system crafted from AISI 316 marine-grade stainless steel. A minimalist, architectural solution for residential and commercial bathrooms — featuring a clean cylindrical spout and signature rose detail. NSF/ANSI 61 certified, lead-free, and corrosion-resistant.
Each set includes a mixer, spout, and in-wall valve with NPT adapters for North American plumbing. Optional matching drain and siphon components complete the installation. Designed by Hans Thyge & Co for d line. Backed by a 10-year warranty. Made in Europe.
