Tile showrooms are organised around how things look. Older houses are organised around what they have settled into over eighty years. The gap between those two facts is where most bathroom tile decisions in Alexandria actually get made — and why the sample that looked perfect on the shelf sometimes turns into a problem on site.
What is under the tile decides what can go on top
Before any conversation about colour, someone needs to look at the subfloor. In a 1920s or 1940s house that usually means original plank subfloor over joists that have been cut into over the decades for plumbing and wiring. Tile is rigid. It does not tolerate deflection, and a floor that feels springy underfoot will telegraph that into cracked grout lines and eventually cracked tile.
The fix is not exotic — sistering joists, adding blocking, laying a proper underlayment or an uncoupling membrane — but it is work that happens before the pretty part starts, and it belongs in the bid. If a proposal jumps straight from demo to tile setting with nothing in between, that is worth a question.
Wet areas need their own answer. A shower that relies on the tile itself to keep water out will fail; the waterproofing sits behind the tile, and that assembly is the difference between a shower that lasts and one that rots the framing quietly for six years. The same principle governs a lot of renovation decisions in this housing stock, and it comes up repeatedly in work on bringing older Alexandria houses up to current standards without stripping out what makes them worth keeping.
Nothing in an old house is square
Large-format tile has been the dominant look for years, and it is genuinely good in a small bathroom — fewer grout lines, less visual noise. But large tile is unforgiving of a substrate that is not flat, and it is equally unforgiving of walls that are out of plumb. Run a big rectangular tile up a wall that leans, and the taper at the ceiling becomes the first thing anyone sees.
Smaller formats, and patterns with some visual busyness to them, absorb that irregularity. This is part of why hexagon, penny round, and classic subway keep reappearing in older bathrooms: they were the practical answer when these houses were built, and they still are.
The floor is going to get wet
Slip resistance gets skipped in showrooms because it is not photogenic. It matters most on a bathroom floor and inside a shower pan, where a polished porcelain that looks superb dry becomes genuinely unsafe wet. Manufacturers publish coefficient-of-friction ratings for exactly this reason; ask for them rather than guessing from the surface texture.
Height is the other floor issue. Adding underlayment plus tile raises the finished floor, and in an old house that can mean a door that no longer clears, a threshold that becomes a trip hazard, or a vanity that suddenly does not fit the reveal. It is a small measurement that causes disproportionate trouble when nobody takes it early.
Grout lines are a maintenance decision disguised as a design one
Tight joints look cleaner and mean less grout to maintain, but they demand tiles with consistent sizing and an installer who can hold the line. Wider joints are more forgiving and read as more traditional. Neither is wrong; they simply cost different amounts of attention later.
Colour choice does real work here too. Grout matched closely to the tile makes a floor read as one continuous surface. Contrasting grout emphasises the pattern, which suits a period bathroom, but shows wear and staining sooner in the highest-traffic strip in front of the vanity.
Where the money actually goes
Homeowners tend to budget tile by the square foot of material and get surprised by the total. In practice, labour, substrate correction, waterproofing, and trim pieces usually outweigh the tile itself, and an intricate pattern can cost more to set than a plainer tile in a more expensive material. A herringbone layout in a modest ceramic can land above a running-bond layout in something far nicer.
That is the useful question to put to a contractor: not what does the tile cost, but what does this layout cost to install compared with the alternative. Vale Construction put out a regional breakdown separating those lines, which is a reasonable reference point when your own quotes come back further apart than you expected.
Restraint tends to age better than ambition here. The bathrooms in these houses that still look right decades on are usually the ones that picked one good material, let the room's proportions do the rest, and spent the difference on the parts nobody sees — an approach that also underpins designing a bathroom around fewer, better decisions.
