A custom solid surface sink program should begin with practical questions, not only reference photos and a target price. The more clearly the buyer defines the program at the start, the easier it is for the supplier to comment on feasibility, sample work, MOQ, packing, and delivery schedule.
This is especially important for bathroom cabinet factories, distributors, hotel suppliers, and OEM buyers. A custom program may affect product drawings, molds, color, finish, labels, carton design, catalog planning, and long-term reorder support.
What model do you need?
Start by defining whether the product is a countertop basin, undermount basin, integrated vanity basin, wall-hung style, vessel basin, or a special project sink. If an existing model is close, share it with the supplier. If the design is new, send sketches, reference photos, target dimensions, and installation requirements.
Review the solid surface basin range before deciding whether a fully custom product is necessary. Sometimes a standard model with a custom size, faucet hole, or finish is enough. In other cases, a new design is justified because the buyer needs a unique catalog item or a project-specific fit.
What sizes are required?
A custom program often includes more than one size. A distributor may need 600 mm, 800 mm, and 1000 mm versions. A hotel project may need different room types. A cabinet factory may need a basin family that fits several cabinet widths. List the size range before sample work begins.
Each size should include outside dimensions, bowl size, bowl position, drain center, faucet hole, overflow, edge detail, and installation method. For special dimensions, use custom size support so the supplier can review what is realistic before quoting.
Is a new mold needed?
A new mold can affect cost, sample time, MOQ, and revision schedule. Ask whether the design can be made from an existing mold or whether a new mold is required. If a new mold is needed, confirm who pays for it, how long it takes, and what happens if the first sample needs adjustment.
The buyer should also ask which details are flexible after the mold is made and which are not. Changing a faucet hole is different from changing bowl shape or outside dimensions. A clear mold discussion prevents expensive late changes.
What finish is expected?
Finish should be chosen with the target market in mind. White, grey, black, matte, satin, and custom finishes all carry different sales and maintenance considerations. For a hotel or apartment project, ease of cleaning and replacement consistency may matter more than showroom effect. For a distributor catalog, the finish should fit the planned product range.
Samples should be reviewed under realistic lighting. Keep sample photos, color references, and finish notes in the approval file. If the product will be photographed for a catalog, confirm whether the final production finish matches the photographed sample.
Is Corian material requested?
Solid Surface is the standard material for QINGDA catalog basins. Corian material can be evaluated for selected custom projects when the buyer specifically requests it. If the program requires Corian, state it early and ask the supplier to review model feasibility, finish, quantity, lead time, and quotation impact.
The Corian material option page can be used during early communication. Keep the wording accurate in product sheets and quotations: Corian is an optional project material, not the default material for every basin.
What packaging is needed?
Custom programs should include packing from the beginning. Ask about carton size, foam protection, corner protection, labels, instruction sheets, pallet option, and export marks. If the basin is long, heavy, or has thin edges, the packing plan may need special review.
For private-label programs, carton printing and label layout may also matter. Decide whether the first order will use neutral packing, buyer branding, or a later branded packaging phase. Packing decisions affect cost and production timing.
What is the target order quantity?
Suppliers need realistic quantity information to quote a custom program. A sample request with no quantity plan is difficult to evaluate. State the expected first order, annual plan if available, and whether the program is for testing, distributor launch, hotel project, or cabinet factory supply.
MOQ may change based on size, color, finish, material option, and mold requirement. Ask for MOQ by model or size rather than one general number. This helps the buyer decide whether the program should start with fewer models or a narrower color range.
What timeline is realistic?
A custom program timeline should include drawing review, quotation, sample production, sample delivery, buyer testing, revision if needed, bulk production, packing, inspection, and shipment. If a project has a fixed installation date, build approval time into the schedule.
Do not treat production time as starting before drawings, sample, material wording, packing, and deposit are confirmed. The project supply support page is useful for connecting production communication with real delivery needs.
What documents should be confirmed?
At the start of a custom solid surface sink program, prepare a file with product drawing, size table, material statement, finish note, sample approval form, packing requirement, carton label, quotation, MOQ, delivery schedule, and inspection checklist. This file should be shared with purchasing, design, engineering, and supplier teams.
If you are ready to discuss a custom solid surface sink program, contact QINGDA with drawings, target models, size range, finish requirements, packing needs, quantity plan, and material options if required.
Finally, decide how the program will be reviewed after the first shipment. Record installation feedback, carton condition, customer comments, cleaning notes, and any repeated questions from distributors or contractors. These notes help the buyer decide whether the second order should keep the same specification or adjust size, finish, packing, or documentation.
