Custom Solid Surface Sinks & Countertops Manufacturer in China

Looking for a manufacturer that can turn your solid surface design into a finished sink, countertop or vanity top?

KSTONE manufactures custom solid surface sinks, integrated countertops, vanity tops and washbasins in China for bathroom, kitchen, furniture and commercial projects.

Unlike suppliers focused only on raw sheets, KSTONE combines acrylic solid surface manufacturing with custom fabrication. This allows us to support customers from material and color selection through CNC machining, basin fabrication, seamless joining, sanding, inspection and export packaging.

Customers can send us a drawing, STEP file, dimensions or reference product for evaluation.

What Solid Surface Sink & Countertop Products Can We Manufacture?

KSTONE supports both standard and customized fabrication, including:

• Integrated solid surface sinks and countertops
• Bathroom vanity tops with integrated basins
• Solid surface washbasins
• Kitchen countertops with sinks
• Wall-mounted washbasin countertops
• Double-basin vanity tops
• Commercial washbasin systems
• Hotel bathroom vanity tops
• Healthcare and public washroom countertops
• Custom furniture tops with integrated basins
• Made-to-drawing solid surface components

Products can be manufactured as finished or semi-finished components depending on how the customer plans to transport, assemble and install them locally.

Integrated Solid Surface Sinks

One of the main advantages of acrylic solid surface is the ability to create sinks and countertops with a visually continuous appearance.

The basin and countertop components are precisely fabricated, bonded with matching acrylic adhesive, sanded and finished to minimize visible joints.

This makes integrated solid surface sinks particularly suitable for:

• Bathroom furniture
• Hotels and apartments
• Residential developments
• Commercial washrooms
• Healthcare environments
• Retail and hospitality interiors

KSTONE can work with different basin shapes, countertop dimensions, edge profiles and installation requirements according to the project.

Custom Vanity Tops & Washbasins

For bathroom furniture manufacturers, distributors and project suppliers, KSTONE can manufacture custom solid surface vanity tops according to cabinet dimensions and customer drawings.

Options can include:

• Single or double basins
• Different countertop lengths and depths
• Custom basin dimensions
• Backsplashes and side splashes
• Built-up edges
• Tap holes and accessory openings
• Wall-mounted configurations
• Customized drainage details

Instead of adapting a project around a fixed standard basin, customers can develop the countertop and basin around their furniture or architectural design.

Made According to Your Drawing

Custom fabrication starts with understanding the product correctly.

You can send KSTONE:

• STEP files
• CAD drawings
• Dimensioned PDF drawings
• Shop drawings
• Reference photos
• Physical samples
• Existing product dimensions

Our team can review the design and discuss material thickness, color, basin geometry, edge construction, drainage details, CNC requirements, joining method, surface finish, packaging and production quantity.

For suitable OEM projects, prototype or sample production can be arranged before mass production.

From Solid Surface Sheet to Finished Countertop

Because KSTONE works with both material production and fabrication, we can manage more of the manufacturing process within one supply system.

A typical project may involve:

1. Drawing Review – checking dimensions, construction and fabrication feasibility.
2. Material Selection – selecting acrylic solid surface color, thickness and matching adhesive.
3. CNC Cutting – precision cutting, routing, drilling and machining.
4. Basin Fabrication – forming or assembling sink components according to the design.
5. Seamless Joining – bonding components with matching acrylic adhesive.
6. Sanding & Finishing – creating a smooth and consistent finished surface.
7. Inspection & Packaging – checking dimensions and appearance before export.

Custom Colors for OEM Projects

Color is especially important for bathroom furniture and interior projects.

KSTONE offers a wide selection of acrylic solid surface colors and patterns and can also discuss custom color matching for suitable project quantities.

This gives OEM customers greater flexibility when developing a product collection or matching an existing interior design specification.

More Than Standard White Vanity Tops

White remains one of the most popular choices for integrated sinks and bathroom countertops, but custom fabrication does not need to be limited to standard white products.

Depending on the project, customers can consider solid colors, neutral tones, particle designs, stone-inspired patterns and other decorative acrylic solid surface options.

This can help furniture manufacturers and designers create more distinctive product collections instead of competing only with standard commodity vanity tops.
