Wash Basin

Wall-hung washbasin used in a compact bathroom

A wash basin is sanitaryware selected by matching its installation type, product dimensions, and faucet configuration to the wash area. Before choosing the bowl shape, confirm whether the product is flat-mounted, under-counter, top-counter, or another listed type, then check the official drawing against the countertop, faucet, and drain plan.

Key specs

Installation type: confirm flat-mounted, under-counter, top-counter, semi-recessed, top-bowl, or the selected product's listed type
Product dimensions: confirm W/D/H and capacity in the selected model's official documentation
Faucet condition: RWL211 is a one-hole example; CL-1500F is a faucet-integrated example
Drawing to confirm: use official CAD and installation drawings for countertop, faucet, drain, and fixing planning

Best for

Situations where this material fits especially well.

Projects that can set the installation type and countertop or cabinet plan before product selection
Quotes that can compare W/D/H, hole or integrated-faucet conditions, and official drawings for each product
Selections that put installation, drain, and faucet questions on the quote before choosing bowl shape and color

Avoid if

Conditions worth checking again before choosing.

The basin installation type and countertop or cabinet plan are still undefined
One product's dimensions or capacity are being treated as a standard for every basin
Faucet, drain, and fixing conditions are being finalized without an official installation drawing

Buying checklist

Items to review when you are close to making a decision.

Has the installation type—flat-mounted, under-counter, top-counter, or another listed type—been set first?
Have W/D/H and capacity been compared with the countertop or cabinet plan for the selected product?
Has the faucet-hole condition or integrated-faucet configuration been checked in the product documentation?
Have the countertop, faucet, drain, and fixing plan been checked against official CAD or installation drawings?
If care performance matters, has separate official documentation been checked for cleaning, stain resistance, or durability?

Warnings

Points that are easy to misunderstand or can lead to defects.

Installation-type labels are a starting point for comparison; actual conditions must be checked in the selected product drawing.
W/D/H, capacity, one-hole, and faucet-integrated labels belong to the named official product examples.
Do not decide countertop cutout, drain position, faucet compatibility, or installation in every wash area from a product name or bowl dimension alone.

Material details

Start with the Installation Type

Choose a wash basin by where and how it will be installed before focusing on the bowl shape. Royal & Co.'s official basin page lists flat-mounted, under-counter, top-counter, semi-recessed, and top-bowl types. Use those labels as a starting point for the installation decision. Even within one type, the countertop, cabinet, faucet, and drain plan need product-specific drawing checks.

Compare Dimensions within the Product Drawing

Width, depth, height, and capacity vary by product. For example, Royal & Co. lists the pedestal-integrated RWL701 at 540 × 450 × 355 mm and 6.5 L, the top-counter RWLT1 at 510 × 455 × 200 mm and 5.4 L, and the under-counter RWLU2 at 465 × 380 × 195 mm and 7.7 L. These are examples for reading the product and installation type together. Do not transfer one product's depth, height, or capacity into another basin's fit or installation outcome.

Check the Faucet and Hole Condition Together

The faucet is not a component to choose after the basin has been finalized. Royal & Co. lists the RWL211 as a flat-mounted, one-hole product, while Daelim Bath lists the CL-1500F as a one-piece, faucet-integrated product. The CL-1500F page provides CAD and installation drawings. Check the selected basin's hole condition, integrated-faucet configuration, countertop plan, and drain plan together against the official drawing and site dimensions.

Questions for the Quote and Site

List the basin product, installation type, W/D/H, faucet plan, and countertop or cabinet plan on the quote. Confirm finish sequence at the wall and countertop, drain position, fixing method, and faucet reach through the selected product's installation drawing and site plan. If cleaning, stain resistance, antimicrobial treatment, or durability affect the decision, consult the selected product's separate official documentation.

How to Read the Official Product Examples

Royal & Co. lists RWL211 as a flat-mounted, one-hole basin at 555 × 455 × 205 mm and 5.6 L; RWLU9 as an under-counter basin at 510 × 395 × 190 mm and 9 L; and RWLA028 as a free-standing counter basin at 585 × 390 × 140 mm and 6 L. Daelim Bath lists the CL-1500F as a one-piece, faucet-integrated example at W525 × D450 × H465 and 13 L. Recheck price, sales status, actual cutout, drain, and faucet conditions through current product drawings and sales or installation documentation.
