The short answer
Specify a bespoke stone bathtub with an agreed design and material record, approved dimensions and drainage, confirmed support and access requirements, and a quotation that identifies responsibilities and approval stages.
Build a clear design brief
Identify the project, proposed bath location, intended use and preferred design reference. Share a measured plan and relevant sections with the design enquiry. Describe the architectural priorities: footprint, rim, basin, visible surfaces, tap relationship and proposed finish.
Where the catalogue is used for inspiration, retain its SKU as a reference and distinguish the concept from the final project specification. Dimensions, weights and capacities remain provisional until they have been reviewed and confirmed.
Define the material approval
Record the proposed stone name and construction, finish reference and visible surfaces. Request current material photographs and document the agreed approach to natural variation. A generic colour label is not a substitute for reviewing the proposed block.
Discuss the relationship between form and material before fixing the geometry. The usable block, machining and finishing access, basin depth and wall requirements are part of the technical review.
Coordinate the interfaces
The architect, structural professional, plumber and installer should share the same approved drawing revision. Confirm support, finished floor relationship, drain and overflow, waterproofing, taps, access and maintainability.
Plan the route through the building and the handover from delivery to installation. The packing dimensions, unloading arrangements and installation responsibility should be reviewed before dispatch rather than left to the receiving team.
- Design reference, final drawing revision and dimensions
- Stone and finish approval record
- Verified weight and support assessment
- Drain, overflow, taps and service access
- Measured access route, lifting and unloading plan
- Quotation inclusions, delivery scope and responsibility
- Approval sequence, care sheet and handover documents
Use approvals to close the specification
A drawing request, a quote and a stone reference are different documents. Record which decisions remain open, who approves them and the next action. Do not convert a requested custom dimension into an accepted manufacturing commitment.
Use the private customer project workspace to share plans and drawings. Ask HANDMADE BATHTUB for the technical information required for the selected proposal; CAD and specification documents should be treated as pending until actually issued for that project.
Common questions
Is a catalogue visualisation a technical specification?
No. It communicates design intent. Approved project drawings, verified material information and technical review establish the production and installation basis.
What should accompany the first enquiry?
Share the project location, measured bathroom plan, preferred SKU or design reference, proposed stone, quantity and the technical questions that need resolution.
Discuss your project
Share your design reference, room plan, stone preference and destination. We can identify the information needed for a project quotation.
