Description

Bulk Bathroom Sink Units – Wall Hung

Wall‑hung sink units are selected for large‑scale restroom projects where floor space must remain unobstructed for cleaning equipment and wheelchair access. The mounting method transfers the sink’s load to the wall structure, requiring precise anchoring and a basin design that resists lateral forces from frequent use.

Design & Engineering

Each unit incorporates a steel support bracket that distributes weight across at least two wall studs or a reinforced concrete backing plate. The basin geometry includes a sloped drain well to maintain a minimum 2 mm water seal and an integrated overflow channel that meets ASME A112.19.2 standards. Faucet decks are pre‑drilled with 35 mm holes to accommodate standard centerset or widespread fixtures.

Materials & Finishes

Vitreous china is the most common material, offering a non‑porous surface with a water absorption rate below 0.5 % and a compressive strength exceeding 40 MPa. For environments requiring impact resistance, 304 stainless steel basins with a 1.2 mm thickness provide a Brinell hardness of approximately 150 HB. Solid surface options allow seamless integration of backsplashes and are available in a range of pigment densities that maintain color stability under UV exposure.

Installation & Compatibility

Rough‑in dimensions typically call for a 150 mm vertical offset from the finished floor to the center of the drain outlet, with a horizontal clearance of 200 mm from adjacent walls to allow for bracket installation. The units are compatible with both wood stud walls (minimum 2 × 4 framing) and concrete masonry walls when using a chemical anchor system rated for at least 1.5 kN shear load. Flexible supply hoses with ½‑inch NPT connections simplify rough‑in plumbing.

Performance & Testing

Static load testing applies a vertical force of 1.5 kN to the basin rim for one minute, with deflection limited to less than 0.3 mm. Water absorption is measured per ASTM C373, confirming the vitreous china stays under 0.5 % after 24 h immersion. Impact resistance is evaluated by dropping a 500 g steel ball from a height of 1 m; no cracking or chipping is observed. Thermal shock resistance is verified by cycling between 5 °C and 80 °C for 25 cycles without glaze failure.

Customization Options

Basin width: 450 mm to 600 mm in 25 mm increments
Basin depth: 140 mm to 200 mm (measured from front lip to drain)
Faucet hole configuration: single‑hole, 2‑hole 102 mm spread, 3‑hole 203 mm spread
Overflow: standard, hidden, or omitted for vessel‑style designs
Finish: gloss white, matte white, biscuit, or custom RAL‑matched solid surface colors
Integrated accessories: soap dispenser hole, towel bar mount, ADA‑compliant front edge radius
Mounting brackets: concealed steel plate, adjustable height brackets for retro‑fit

Quality Assurance

Dimensional inspection is performed on a coordinate measuring machine with a tolerance of ±0.5 mm on critical interfaces such as bolt hole patterns and drain outlet positions. Glaze uniformity is assessed using a reflectance meter to ensure a gloss variance of less than 5 % across the surface. Each batch undergoes a hydrostatic pressure test at 6 bar for 5 minutes to verify leak‑free seals before packaging.

Applications

In hotel lobbies and guest rooms, wall‑hung sinks free up floor area for housekeeping carts while presenting a clean, modern aesthetic that simplifies daily cleaning. Healthcare facilities benefit from the reduced crevice count, which lowers the risk of pathogen accumulation and supports infection‑control protocols. High‑traffic venues such as airports and stadiums rely on the units’ load‑rated brackets to withstand repeated loading from heavy public use without compromising wall integrity.

Frequently Asked Questions

Can dimensions be customized? Yes. Basin width, depth, and faucet hole spacing can be adjusted in 25 mm increments to match project layouts.

What information is required before quotation? Provide rough‑in dimensions, wall substrate type, desired material, finish, and any accessory holes (soap dispenser, towel bar).

What materials are available? Vitreous china, 304 stainless steel, and solid surface. Each option has distinct thickness, absorption, and impact properties.

How is quality inspected? Dimensional checks via CMM, gloss uniformity measurement, hydrostatic pressure testing, and visual inspection for glaze defects.

What packaging methods are available? Units are packed in double‑wall corrugated cartons with corner protectors and foam edge guards; palletized for LTL or FCL shipment.

How are export shipments protected? Cartons are strapped to pallets, wrapped in stretch film, and include moisture‑absorbent desiccant packs.

What is the typical production lead time? 4–6 weeks after receipt of approved drawings and deposit, depending on material and finish selection.

How are samples arranged? Sample units can be shipped via express courier; charges are credited against the first order.
