Size of a Urinal — Standard Urinal Dimensions, Mounting Heights and Spacing
A urinal bowl itself is small; what decides whether a washroom works is the height it is fixed at and the space between each one. These are the standard urinal sizes and the clearances to plan around before the waste points are set.
Standard urinal sizes
Typical production ranges. Always work from the model drawing for a live project.
| Type | Width | Projection from wall | Height |
|---|---|---|---|
| Wall-hung bowl urinal | 330-400 mm (13-16 in) | 280-350 mm (11-14 in) | 500-700 mm (20-28 in) |
| Compact wall-hung urinal | 280-330 mm (11-13 in) | 250-300 mm (10-12 in) | 400-500 mm (16-20 in) |
| Corner urinal | 300-380 mm along each wall | 280-330 mm | 450-600 mm (18-24 in) |
| Floor-standing stall urinal | 400-460 mm (16-18 in) | 350-400 mm (14-16 in) | 1000-1100 mm (39-43 in) |
| Waterless urinal | 330-400 mm | 280-350 mm | 550-700 mm |
Urinal heights and spacing
| Dimension | Standard | Notes |
|---|---|---|
| Rim height, adults | 600-650 mm (24-26 in) from floor | The usual height for a wall-hung urinal |
| Rim height, accessible | Up to 430 mm (17 in) | One lower urinal in a public washroom |
| Rim height, children | 350-450 mm | Lower for younger children |
| Centre to centre | 600 mm minimum, 700-750 mm comfortable | Less feels cramped and splashes |
| Centre to side wall | 380 mm minimum, 450 mm comfortable | Same rule as a WC |
| Clear floor in front | At least 600-750 mm | More in a busy washroom walkway |
| Privacy screen | 400-600 mm projection | Fixed about 300 mm above the floor |
Planning a row of urinals
Start from the spacing, not the bowl. A row of urinals at 700-750 mm centres feels comfortable and keeps splashes off the neighbour; at the 600 mm minimum it works, but only with privacy screens. Add 380-450 mm from the last urinal centre to any side wall.
Include at least one lower urinal in any public washroom — rim at about 430 mm — for children and wheelchair users. It costs nothing extra and saves a separate accessible fixture being used for the purpose.
Fix the waste and supply points only once the model is chosen. Outlet height and position vary between models, and a waste point set for one urinal can leave another sitting at the wrong height. Tile the wall behind the row to at least 1200 mm with a matt floor tile underneath, because urinal areas are cleaned wet every day.
Frequently asked questions
What is the standard size of a urinal?
A standard wall-hung urinal is about 330-400 mm wide, projects 280-350 mm from the wall and is 500-700 mm tall. Floor-standing stall urinals are about 400-460 mm wide and 1000-1100 mm tall.
What is the standard urinal height from the floor?
About 600-650 mm (24-26 in) from the floor to the rim for adults. An accessible urinal has its rim at no more than about 430 mm (17 in), and children's urinals are mounted at around 350-450 mm.
How far apart should urinals be?
At least 600 mm between centres, and 700-750 mm is more comfortable. Allow 380-450 mm from the centre of the end urinal to the side wall.
What size is a corner urinal?
A corner urinal typically measures about 300-380 mm along each wall, projects about 280-330 mm from the corner and stands 450-600 mm tall.
How much space does a urinal need?
Allow a width of about 700-750 mm per urinal in a row, or 760-900 mm for a single urinal between walls, with at least 600-750 mm of clear floor in front.
