10 Factors That Influence Your Quote
The cost of a tiling project is shaped by much more than the number of square metres. A professional tiling quote considers the tiles being installed, the condition of the surface, the room, the layout, access to the site and the preparation needed before installation can begin.
If you are researching tiling costs in Perth, it is useful to understand how tiling quotes are calculated. Two areas of a similar size can require very different amounts of labour, materials and planning. A clear quote should reflect the actual scope of the work so there are fewer surprises once the project is underway.
Below are ten of the main factors that can influence your quote.
1. Size of the Area
The total wall or floor area is an important starting point because it affects the amount of tile, adhesive, grout and labour required. Measurements also need to account for the full installation area, including returns, recesses, steps and other surfaces that may not be obvious from a basic room dimension.
A larger, open floor may create efficient working runs. A smaller bathroom can contain more corners, fixtures and detailed cuts within each square metre. This is why area alone does not provide a complete picture of the work involved.
2. Type and Size of the Tiles
Ceramic, porcelain, natural stone, large-format tiles and mosaics each need a suitable installation approach. Tile weight, thickness, edge type, surface variation and intended application can influence handling, cutting, preparation and the products used.
Large-format tiles may require careful substrate preparation, handling and levelling to achieve a consistent finish. Mosaics involve many joints and can take more time around sheets, edges and transitions. Natural stone may need additional care and, depending on the product, sealing or other material-specific steps.
Choosing the tile early helps the tiler assess the job accurately. Gun Tiling’s tile supply service connects customers with tile options, and the wider range at Gia’s Bathrooms & Tiles can help homeowners compare sizes, finishes and applications before the quote is finalised.

3. Floor Tiling Versus Wall Tiling
Floors and walls present different installation conditions. Floors need to be assessed for flatness, movement, levels, transitions and the way the tiled surface will meet adjoining finishes. Wall tiling can involve vertical set-out, corners, niches, windows, fittings and finished edges.
The quote should identify which surfaces are included and the preparation each one requires. For larger floor areas, learn more about Gun Tiling’s professional floor tiling in Perth.
4. The Room and How It Is Used
A bathroom, kitchen, laundry and living area may have a similar tiled area but a different scope. Bathrooms and laundries can involve wet-area details, floor wastes, falls, penetrations and coordination around fixtures. Kitchens often require careful splashback set-out around cabinetry, power points and windows. Living areas may involve long sightlines, doorway transitions and large continuous floor sections.
The room’s function helps determine the materials, preparation, detailing and installation sequence needed for the job.
5. Surface Preparation Required
Tiles need a suitable surface beneath them. Before pricing the installation, a tiler may need to assess whether the substrate is sound, clean, sufficiently flat and ready for the proposed tile system.
Preparation can include cleaning, patching, grinding, levelling, screeding or addressing unsuitable areas before tiling begins. Cracks, movement, uneven floors, damaged sheeting or adhesive residue can add time and materials. This work may not be visible in the finished room, but it is an important part of doing the job properly.
6. Tile Removal and Disposal
If existing tiles need to come up, the quote may need to include removal, dust control, loading, transport and disposal. The time involved depends on the type of tile, the adhesive, the substrate, the thickness of the existing build-up and how easily the area can be accessed.
Removal can also reveal surface damage or preparation needs that were not visible beforehand. Where old finishes are part of the scope, ask whether a dedicated tile removal service and disposal are included in the quote.

7. Waterproofing Requirements
Wet areas may require waterproofing as part of the project. The size and configuration of the area, the condition of the substrate, junctions, penetrations, wastes and the proposed installation all influence the waterproofing scope.
A quote should make clear whether waterproofing is included, who is responsible for it and what preparation must be completed first. Treating waterproofing as a defined stage of the job helps protect the tiled system and supports a reliable long-term result.
8. Site Access and Working Conditions
Access affects how materials, tools and waste move through the property. Stairs, upper floors, narrow entries, limited parking or long carrying distances can add handling time. Work in an occupied home may also need additional protection, dust management and coordination so the household can continue to use other areas safely.
Clear information about access helps the tiler plan labour, equipment and site protection accurately.
9. Pattern and Layout Complexity
A straight, simple layout is generally different to pricing a herringbone pattern, a feature wall, detailed borders or a layout that must align across several surfaces. More complex patterns can involve additional set-out, cutting, checking and wastage.
The number of corners, niches, columns, floor wastes and penetrations also matters. A professional tiling quote should reflect the proposed layout rather than assuming every square metre takes the same amount of time.

10. Grout, Trims and Finishing Details
The finishing specification can affect both materials and labour. Grout type and colour, joint width, silicone joints, edge trims, mitred edges, movement joints, thresholds and transitions should be considered before work begins.
These details are small compared with the full area, but they influence the final appearance and how neatly the tiled surfaces meet fixtures, walls and adjoining floors. Confirming them early also makes it easier to compare quotes on the same scope.
How Are Professional Tiling Quotes Calculated?
A professional tiling quote is usually built from the complete scope of work. That can include site assessment and set-out, surface preparation, removal, waterproofing where required, installation labour, adhesives and grouts, trims and finishing, site protection, waste handling and other project-specific needs.
Not every quote includes the same items. Before comparing totals, check that each contractor has priced the same surfaces, tiles, preparation and finishes. A lower figure may simply exclude work that another quote has clearly allowed for.
What Information Helps Produce an Accurate Quote?
Providing clear information at the start helps reduce assumptions. Useful details include:
- the property address and room or area being tiled
- approximate dimensions, plans or measured wall and floor areas
- photos of the current surfaces, access points and adjoining finishes
- the selected tile, including material, dimensions and edge type
- the preferred pattern, grout colour, trims and other finishing details
- whether existing tiles or fixtures need to be removed
- known issues such as cracks, uneven surfaces or previous water damage
- whether the home will be occupied during the work
- the expected project timing and any coordination with other trades.
For some projects, photos and plans can support an initial discussion. A site inspection may still be needed to confirm measurements, surface condition, access and preparation before the scope is finalised.
Frequently Asked Questions
How much does tiling cost in Perth?
There is no single reliable rate for every tiling project. Area is one factor, but tile type, preparation, removal, waterproofing, layout, access and finishing details can materially change the scope. The most useful price is one based on the actual project and clear inclusions.
Is a cheaper tile always cheaper to install?
No. The purchase price of the tile and the installation cost are separate. A lower-cost tile may still require complex set-out, additional preparation or time-consuming cuts. Tile size, material, consistency and pattern can all affect installation.
Why do two tiling quotes differ?
The quotes may be based on different inclusions, preparation allowances, materials or assumptions. Compare the scope line by line and ask whether removal, disposal, waterproofing, adhesives, grout, trims, protection and finishing are included.
Can I get a tiling quote from photos?
Photos, dimensions and plans can be useful for an initial review, but they may not show levels, substrate condition, access or concealed issues. Depending on the project, an on-site assessment may be needed before the scope is confirmed.
Do tiling quotes include tiles and materials?
It depends on the quote. Some projects include supply of tiles and installation materials, while others are priced for installation only. Ask for the inclusions to be listed clearly so you know who is supplying the tiles, adhesive, grout, trims and other products.
How can I keep the project cost under control without cutting corners?
Make tile and layout decisions early, choose a pattern that suits the budget, provide accurate information, keep the work area accessible and confirm the full scope before work starts. Simplifying unnecessary layout complexity can reduce labour while still allowing the preparation and installation to be completed properly.
Should I choose my tiles before requesting a quote?
You can begin the conversation before choosing tiles, but the final selection helps produce a more accurate quote. Share the tile material, dimensions, finish and proposed pattern before the scope is confirmed.
