Wash basins - Connecting dimensions
This European Standard specifies the connecting dimensions of wash basins in accordance with EN 14688 regardless of materials used for their manufacture.
NOTE 1 Other connecting dimensions are permitted, e.g. special designs of wash basins, if the manufacturer supplies or recommends the appropriate fitting.
NOTE 2 The shape of the appliance in the figures is for illustration only; it in no way prejudices the final shape of the appliance, which is left to the initiative of the manufacturer.
Waschbecken - Anschlussmaße
Diese Europäische Norm legt Anschlussmaße für Waschbecken nach EN 14688, unabhängig vom für ihre Herstellung verwendeten Werkstoff, fest.
ANMERKUNG 1 Andere Anschlussmaße sind zulässig, z. B. für spezielle Ausführungen von Waschbecken, wenn der Hersteller eine geeignete Ablaufgarnitur mitliefert oder empfiehlt.
ANMERKUNG 2 Die in den Bildern dargestellte Form der Gegenstände wurde nur für das bessere Verständnis gewählt; sie schreibt nicht die endgültige Form der Gegenstände vor, die der Wahl des Herstellers überlassen bleibt.
Lavabos - Cotes de raccordement
La présente Norme Européenne spécifie les cotes de raccordement des lavabos conforme à EN 14688, quels que soient les matériaux entrants dans leur fabrication.
NOTE 1 D’autres cotes de raccordement sont possibles, dans le cas, par exemple, de conceptions particulières de lavabos, si le fabricant fournit ou recommande les dispositifs de robinetterie appropriés.
NOTE 2 La forme des appareils représentés sur les figures est donnée uniquement à titre d’illustration ; elle ne préjuge en rien de la forme définitive de l’appareil qui est laissée à l’initiative du fabricant.

Overview
EN 31:2011+A1:2014 (CEN) - "Wash basins - Connecting dimensions" specifies the standardized connecting dimensions for wash basins (sinks) as referenced to EN 14688. It defines the critical geometric interface points - tap holes, waste outlet holes, integral overflow arrangements and fixing points for wall-hung basins - regardless of material or final shape. The standard includes tolerances, minimum radii and platform requirements and an informative gauge example (Annex A) to verify waste outlet dimensions.
Key Topics and Requirements
- Scope & applicability
- Applies to wash basins of all materials and most designs; special designs are permitted if the manufacturer provides compatible fittings.
- Intended to ensure compatibility between wash basins and standard taps, wastes and wall fixings.
- Tap holes
- Requirements cover single central, side (one or two) and three‑hole configurations.
- Specifies horizontal clearances to bowl edges, minimum back‑wall offsets, minimum radii on tap platforms and maximum platform thickness to ensure tap fit and sealability.
- Example dimensional constraints include minimum radii (r1 ≥ 25 mm, r2 ≥ 30 mm, r3 ≥ 32 mm) and platform thickness (s ≤ 18 mm); lateral clearances such as g1 ≤ 80 mm and g2/g4 ≤ 65 mm are defined.
- Waste outlet and overflow
- Defines bore, seal base diameter and reference diameters for measuring outlet height, plus minimum bowl depth to reference plane.
- Minimum seal base diameter (d4 ≥ 60 mm) and reference diameter (d5 = 63 mm) are specified; minimum bowl depth to reference plane h2 ≥ 2 mm and limits on cone angle (≤ 100°).
- Annex A gives a gauge example for verification.
- Fixing dimensions for wall‑hung basins
- Fixing hole spacing and hole-size minimums are specified relative to basin width; common values include a nominal fixing centre spacing of 280 ± 10 mm for many widths, and hole-width minimums (e.g., 20 ± 2 mm for wider basins).
Applications - Who uses EN 31
- Manufacturers of ceramic, metal or composite wash basins to design universally compatible connection points.
- Plumbing and sanitary fittings suppliers to ensure taps, wastes and fixes fit standard basins.
- Architects, specifiers and consultants to select compliant sanitary appliances for projects.
- Installers and testing laboratories for verification, quality control and acceptance testing (using the gauge in Annex A).
Related Standards
- EN 14688 - Sanitary appliances: wash basins - functional requirements and test methods (normative reference).
- Other national/adopted versions of EN 31 (CEN members) for local implementation.
