What Affects the Cost
Bathroom size and scope. Small ensuites cost less overall but more per square metre due to the higher ratio of cuts to open runs. Full floor-to-ceiling tiling of a family bathroom adds significant material and labour.
Tile type. Ceramic subway tiles ($20–$40/m2 supply) and basic porcelain ($40–$80/m2) are the most affordable. Large-format porcelain is growing in popularity across Adelaide. Natural stone is less common here than in Sydney or Melbourne but appears in heritage home restorations at $80–$200+/m2.
Beaumont Tiles is headquartered in Adelaide and operates multiple showrooms across the city, including Melrose Park and Mile End.
Reactive clay soils. Parts of Adelaide sit on reactive clay. Slab movement from seasonal moisture changes can crack tiles and grout lines. In reactive clay areas, your tiler should use flexible adhesive and install additional movement joints to accommodate slab movement. This adds a modest material premium but prevents cracked tiles within the first few years.
Old tile removal. Removing existing tiles adds $25–$50/m2. In older Adelaide homes with original encaustic or concrete tiles set in thick mortar beds, removal is more labour-intensive ($40–$65/m2) and the substrate underneath often needs significant repair.
Heritage tile replication. Adelaide has a large stock of character homes with original encaustic or tessellated tile floors. Replicating heritage tile patterns with reproduction tiles is specialist work, typically quoted by the project rather than by the square metre, and costs significantly more than standard tiling.
Substrate condition. Older rendered brick walls need assessment. If the lime render is loose or sandy, it must be stripped and replaced before tiling. Properties built before 1950 often need an extra day of preparation for wall correction alone.
Underfloor heating. Like Melbourne, Adelaide's cooler winters make underfloor heating increasingly popular. Electric mat systems ($50–$90/m2 supply and installation) must go down before tiles and require flexible adhesive over the mats.
A straightforward ensuite retile in a 1990s Mawson Lakes or Golden Grove home with porcelain tiles and standard layout sits toward $1,700. A heritage bathroom in Norwood with old mortar-bed tile removal, reactive clay slab repairs, feature tiling, and substrate correction pushes toward $10,400.
Adelaide-Specific Considerations
Adelaide's mix of character homes, post-war housing, and newer suburban estates means bathroom tiling complexity varies significantly by location.
Reactive clay soils (Salisbury, Elizabeth, Parafield Gardens, parts of the Fleurieu Peninsula). During dry summers, the clay shrinks; during wet winters, it expands. This seasonal movement can crack concrete slabs and, in turn, crack tiles and grout. If your home is in a reactive clay area, your tiler should use flexible adhesive (not standard cement-based) and install additional movement joints to accommodate slab movement. Movement joints should be placed at maximum 4.5m intervals on floors and at all wall-floor junctions. Shower floor tiles should meet AS 4586 P3 minimum for wet barefoot areas.
Character homes (Norwood, Unley, Prospect, Goodwood, Hyde Park). Adelaide's character home stock is extensive. Many of these homes have original encaustic or tessellated tile floors in bathrooms and hallways, set in mortar beds 30–50mm thick. Some homeowners want to replicate these patterns with reproduction tiles, which is specialist tiling work. Others want modern tiles but need the old mortar bed removed first, which is a considerably bigger job than removing modern thin-set tiles from a slab. Tile retailers like Amber in Prospect carry reproduction encaustic ranges for heritage restorations.
Post-war suburbs (Glenelg, Marion, Edwardstown, Campbelltown). Homes from the 1950s–1970s with concrete slab bathrooms. Tiles from this era are often small ceramic mosaics set directly in mortar. Removal is time-consuming but the concrete substrate underneath is usually sound. These properties tend to sit in the middle of the price range.
Newer estates (Mawson Lakes, Seaford, Golden Grove, Munno Para). Modern plasterboard walls and concrete slab floors. Straightforward preparation, predictable costs. These homes sit at the lower end of the range with minimal substrate correction needed.
Hiring a Licensed Tiler in SA
In South Australia, tiling work is classified as building work and requires a Building Work Contractor's Licence issued by Consumer and Business Services (CBS). The restricted builder category for tiling applies.
A good tiler will ask about your home's soil conditions (especially in the northern and southern suburbs), inspect the existing substrate, and specify the adhesive type based on whether your home is on reactive clay or stable sand.
Worth checking:
Public liability insurance
That waterproofing will be completed by a licensed waterproofer and inspected at the mandatory hold point before tiling starts
Movement joint placement plan if your home is in a reactive clay area
