Thank you so much!! We’re thrilled to hear that! The vertical seams are black grout, which tie in with the matte black plumbing fixtures and black schluter trim. We loved the way that the black grout tied into the plumbing fixtures but also provided a contrast to the warm cement-looking porcelain tiles. It’s a clean, modern edge, but also keeps the zen spa bath vibe intact. The shower curb is leathered black absolute granite. We like the way you think!
