Letting the Module Set Out the Room

A setting-out direction that sizes the openings, recesses and runs a surface has to fill in whole modules of the chosen material, so the awkward cut is designed out early rather than discovered at the last course.

Where this idea works

Where this idea works

Contexts this direction tends to suit — and, honestly, where it may not.

  • Tiled bathrooms, splashbacks and wet rooms where cuts would be conspicuous
  • Panelled and slatted wall runs with a repeating unit
  • Niches and recesses still being formed in construction
  • Projects where room dimensions and joinery sizes can still move

Where it may not fit

Where it may not fit

  • Fixed openings and existing recesses whose dimensions cannot change
  • Continuous, jointless finishes that have no module to set out
  • Work where the material is already ordered and cut

Planning

Planning considerations

  • Fix the module before the room's dimensions are frozen, because a recess can move more easily than a unit can be made bigger
  • Joint width is part of the module, since it is a run of units plus its joints that has to fit
  • Where a cut cannot be avoided, choose which edge takes it instead of leaving that to the installer
  • Setting out is a drawing rather than a conversation on site, so ask for it before anything is ordered

Layout

Layout considerations

  • Set out from the most visible edge or corner outward so the cut lands where it is least seen
  • Dimension niches and recesses to whole units, including joints, so the recess needs no cut at all
  • Check the module against doors, sockets and outlets, which interrupt a run wherever they fall
  • Align the first joint with something the room already has, such as an opening reveal

Materials & finishes

Materials and finishes to discuss

Named generically as starting points to discuss with professionals — not specifications, and not priced.

Consider:Tile in a chosen formatWall panelling boardsSlatted or fluted panelsSheet materials with a fixed widthTrims and stop beads at terminationsGrout and joint widths as part of the module
  • A sliver cut is fragile at its edge and is usually the first piece to crack or lift
  • Cut edges may need a trim or edge protection depending on the material, which is a point for the installer

Maintenance & durability

Maintenance and durability questions

  • A narrow cut piece is difficult to replace neatly once it is damaged
  • Spare units from the same batch make a later replacement far more likely to match

Professional review

What to ask a qualified professional

Bring these questions to a designer, contractor or the relevant qualified professional or authority.

  • Can the designer or installer produce a setting-out drawing before the units are ordered?
  • Where will the cut piece land, and is that the least visible edge available?
  • Can this niche be dimensioned to whole units including the joints?
  • How would the installer finish or protect a cut edge in this material?
  • How many spare units from this batch should be kept, and where?
