Bathroom Tiling in Port Adelaide

Sometimes yes, with caveats. Original encaustic and terracotta tiles can be lifted if they're set in mortar bed rather than adhesive, and relaid after substrate work — but success rates vary. Tiles that have been down for 80+ years may be fragile, and breakage during removal is possible. We assess the original installation during the initial inspection and give an honest assessment of the likely success rate. We'll never tell you we can definitely preserve original tiles when the risk of breakage is high.

For heritage context in Port Adelaide, the tiles that work best have the warmth and variation of natural materials: handmade-look Spanish or Portuguese tiles in terracotta or warm cream; cement encaustic reproduction tiles for feature floors; stone-look porcelain in aged limestone or slate tones; or classic subway tiles in warm white for a 1910s aesthetic. Avoid: large-format polished porcelain slabs, pure geometric modernist patterns, or anything that reads as contemporary high-gloss — these clash with the character of these homes.

Sometimes — but it's not always advisable. Tiling over existing tiles only works if the original tiles are completely sound (no drummy tiles, no cracks), the combined thickness won't cause issues with door clearances or fixtures, and the additional weight is appropriate for the substrate. In a bathroom renovation we almost always recommend stripping the original tiles so we can inspect and repair the waterproofing and substrate underneath. We'll give you an honest assessment for your specific situation.

A drummy tile sounds hollow when tapped — it indicates the tile has separated from the adhesive or substrate underneath. This happens when original installation had insufficient adhesive coverage, when the substrate has moved, or when moisture has compromised the bond. Drummy tiles are at risk of cracking or lifting, and they indicate that the adhesive system underneath has failed. The only correct fix is removal and relay — topical treatments don't work.

Large format tiles require a quality wet-cutting tile saw with a diamond blade — not a simple score-and-snap tile cutter. We have the right equipment for any tile size, including rectified porcelain tiles which are particularly unforgiving of poor cutting technique. We also have angle grinders with diamond cups for curved cuts around pipes and architraves.

For most straightforward rectangular rooms with standard tile layouts, budget 10–15% wastage. For diagonal layouts, complex rooms, or very large tiles with longer cuts, budget 15–20%. We'll calculate your exact requirement at quoting stage based on the specific tile size and your room dimensions, and advise on how many extra tiles to keep in reserve for future repairs.

Counter-intuitively, larger tiles often make small bathrooms feel bigger — not smaller. A 600×600mm or 600×1200mm tile with fine grout joints creates a calmer visual field with fewer lines chopping up the space. Small mosaic tiles (50×50mm) on a floor can look busy and make the room feel cramped. That said, if you're working with a room that has lots of awkward angles, smaller tiles reduce the proportion of cut tiles, which is a practical consideration. We'll advise on what works for your specific room.

Using the same tile on floor and walls is a popular contemporary approach — it creates a seamless, cocoon-like feel and can make a small bathroom feel much larger. However, there's an important technical caveat: floor tiles must have an appropriate slip resistance rating (P3 or better for domestic bathrooms to comply with AS 4586), and wall tiles specified for wall-only use may not meet this. If you want the same tile look on floor and wall, we need to check the slip resistance rating of the tile you've chosen before specifying it on the floor.
