Waste, Cuts and Coverage Add Up

Tiling quantities look simple on paper. Then you add waste, the cut tiles at every wall and door jamb, the real adhesive coverage rate and the grout volume.

A 900 by 900 tile on a 3mm joint and a mosaic on a 1mm joint are two completely different material orders off the same floor area.

We estimate tiling for Perth residential and commercial projects, covering floor tiles, wall tiles, feature tiles, large format, mosaic and external pavers. Numbers your tiler can order from and your client can trust.

What We Cover in a Tiling Estimate

Element	How We Calculate It	Notes
Floor tile area	m2 by room, less fixtures and built-ins	Waste factor 5-15% by tile size and cut complexity
Wall tile area	m2 by elevation, less openings and fittings	Feature areas at higher waste rate
Tile quantities	m2 area divided by tile size x boxes/m2	Rounding to full box quantities
Adhesive	kg calculated by coverage rate for tile/surface type	Rectified vs pressed tiles have different bed depths
Grout	kg by joint width, depth and tile area	Different rates for sanded vs unsanded grout
Waterproofing	m2 wet areas at 250mm upstand minimum	Lagging to penetrations included
Trim profiles	LM of aluminium or stainless transition strips	Expansion joints at substrate changes
Labour	Hours by tile size, surface and pattern complexity	Diagonal and herringbone at higher labour rate

Standard tiling estimate elements. External tiling and pool tiling have additional requirements including anti-slip ratings, frost resistance and submerged adhesive specifications.

Why Waste Factors Matter in Tiling Estimating

Tile waste factors are not a fixed percentage. A small mosaic tile in a square room with straight-cut edges might waste 5%. A 900x900mm large-format tile in an L-shaped bathroom with 45-degree cuts around a freestanding bath can waste 20% or more. An accurate Perth tiling estimate applies a waste factor based on the actual floor plan shape and tile layout, not a blanket percentage.

Residential Tiling Room by Room

A residential tiling estimate is really three jobs stacked together. Wet areas, floor tiling through the living zones, and wall tiling at splashbacks and features.

Each one carries its own specification and its own waste factor, so we measure and rate them separately rather than running one rate across the house.

What Gets Measured Separately

Bathroom and ensuite floor and wall, with waterproofing, niches and feature strips
Kitchen splashback, either full height or standard, in metro tile or large format
Living and dining floor, whether full-house tiling or selected rooms
Alfresco and outdoor entertaining in external rated tiles or pavers
Laundry floor and partial wall tiling
Lobby and hallway entry feature tiles or consistent floor tile

The Tile Size Decides The Labour

A big tile covers ground faster and then punishes you everywhere else. It needs a flatter substrate, a deeper adhesive bed, levelling clips and often two people to place a single tile.

The same room in mosaic is slower per square metre but forgiving on the floor prep. Neither one is more expensive by default, which is exactly why a single blanket tiling rate keeps getting builders into trouble.

We rate the labour to the tile that is actually specified, and if the selection is not locked in we price the likely option and flag it.

Commercial Tiling Estimating

Commercial tiling means larger areas, more complex layout patterns and higher specification products.

Retail, hospitality, aged care and office fitouts each carry their own anti-slip, durability and maintenance requirements. Those requirements drive the product selection and the labour rate, so they get read before anything is priced.

Common Questions

Straight answers on how we price tiling estimating in Perth. If yours is not here, send your plans and just ask.

Waste is calculated based on the tile size relative to the room dimensions, the number of cut edges, and the lay pattern. A diagonal or herringbone pattern wastes more than a straight lay. We apply a waste factor based on the actual room shape, not a standard percentage.

Yes. Adhesive quantities are based on the coverage rate for the adhesive product type (thin-set or thick-bed) and the tile format. Grout is calculated from the joint width, depth and area. The formula is different for fine-joint rectified tiles versus wide-joint pressed tiles.

Yes. Pool tiling requires submerged-rated adhesive, epoxy grout and a tile with appropriate water absorption classification. We quantify the pool shell area and waterline tiles separately and apply the correct product specifications.

Yes. If you are estimating a full bathroom renovation, we can estimate tiling as one component alongside waterproofing, fixtures and other trades.
