Bathroom pieces need drawings early
A custom stone vanity is a furniture, plumbing, waterproofing, and installation decision at the same time.
Formal pricing should use drawings, waste and plumbing positions, wall support assumptions, builder timing, access notes, and the preferred stone family.
Stone suitability is a wet-area issue
Not every marble is a practical wet-area choice. Finish, sealing, porosity, cleaning expectations, and use intensity matter.
Quartzite and sintered stone should be considered where durability and cleaning are primary concerns.
Installation boundaries must be clear
The quote should define what April's Form supplies, what the builder or installer controls, and what site conditions must be verified before delivery.
This is the bathroom trust layer that strong bathware competitors use well, and April's Form Australia needs the same clarity.
