The house you never see
Scroll — main, branches, fixtures, flow: the rough-in assembles inside a ghost of the house. Drag to walk the frame. Click the valve — and feel what shut-off means.
When it’s right, nobody ever thinks about it again. That silence is the product — and it’s built joint by joint.
Behind the Walls is a BaseBloom assembly concept for plumbing companies: a rough-in visual that explains the repipe estimate, an emergency lane that answers at 2am, and fixture pages priced like you actually price them.
Service line to stack — sized right, sloped right, done once. The backbone the whole house drinks from.
Every fixture fed and vented. The drawing your customer never sees, until this page shows them.
Heaters, sinks, tubs — the visible 10%. Flat honest ranges a homeowner can budget from tonight.
