U15 Ultimate Toilet Door Sizing

U15 Ultimate doors are normally made to the standard sizes shown in the table below. If you need custom sizes, please contact us, as size limitations do apply. 

When fitting to steelwork or timber, we normally allow 5mm clearance on the width and 5mm on the height of a doorset. When fitting to masonry, we increase the clearances to 8mm on the width and 8mm on the height, to compensate for slight variations in the structural opening.

In general, clearances should be kept tight on the width for a neat appearance, but on the height, more clearance is advisable to allow for the arc of movement as the doorset pivots towards vertical during installation.

We always advise that actual structural openings are measured, if possible after the floor has been laid. Please do not assume that structural openings will be constructed exactly to the size shown on the architect’s drawings.

* Door open to 90° and no allowance made for protruding handles. Contact us to ensure compliance with current Part M requirements or when clear opening dimensions are critical.
