Tiling in an older house
Tiling is the finish most people judge a bathroom by. In the Highlands there is an extra consideration: the room sits inside a house that often has real character, and the tile choice can either belong to that house or look like it arrived from a display centre.
That does not mean reproducing a 1910 bathroom. It means choosing tiles with some texture and proportion that relate to the period, and setting them out with care.
Choosing tile for a character home
Some combinations that consistently work in Bowral and Burradoo houses:
- Encaustic-look porcelain on the floor — the pattern of traditional cement tiles with the durability and water resistance of porcelain.
- Hexagonal or penny-round mosaic floors, particularly in white or a soft neutral with a darker grout.
- Handmade-look subway tiles on the wall, laid in a traditional running bond or a vertical stack.
- Honed, stone-look porcelain in warm tones, which suits the sandstone of the region.
- A picture rail or dado line carried through in tile, where the rest of the house has one.
What tends to look out of place: very large glossy rectified grey tiles, stark white gloss throughout, and feature walls that bear no relation to the rest of the house.
In a newer Mittagong or Moss Vale house, the palette is wider — but the same principle applies. Choose tile that suits the house, not the showroom.
Tiling over timber floors
Many older Highlands houses have suspended timber floors. Timber moves with temperature and moisture. Tile does not. Tiling directly over timber boards or particleboard guarantees cracked tiles and failed grout.
The correct build-up is: sound joists at appropriate spacing, a compressed fibre cement or equivalent wet-area sheet fixed to them, a membrane, and then tile. If the joists are undersized, spaced too widely or damaged from past leaks, they are fixed first. Skipping that step is the most common reason older bathroom floors crack within a few years.
Full height, and why it suits the climate
Tiling the wet zones to the ceiling is standard on our jobs rather than an upgrade. It looks better — it removes the horizontal tile line that divides the room — but in the Highlands there is a practical reason too. Painted plasterboard above a tile line peels, bubbles and grows mould in a bathroom with heavy winter condensation. Tile does not.
Underfloor heating goes in now or never
An electric heating mat is laid in a thin bed over the waterproofed floor and tiled over. The thermostat, sensor and circuit are roughed in before any of that happens.
Once the floor is tiled, adding it means taking the floor up. So the decision needs to be made at selections, not halfway through the job. In a Bowral bathroom, it is rare for anyone to regret it.
Set-out
A good tile set-out is planned before the first tile goes down:
- Cuts are balanced so no wall ends in a thin sliver.
- The shower niche aligns with the grout lines.
- Tapware and rose positions sit on a grout line or a tile centre, not randomly.
- Floor tile falls to the waste without awkward cuts across the shower.
- Internal corners and floor junctions are sealed with flexible sealant, not grout, because they move.
Slip resistance
Wet floors should carry an appropriate slip rating. Honed or textured finishes are safer than polished in the shower. Mosaic tiles add grip through the extra grout lines. A lot of Highlands homeowners intend to stay in the house for the long term, and a safe floor is part of that.
Where tiling fits in the program
Tiling follows waterproofing and comes before fit-off. Mosaics and traditional bonds take longer than large-format tiles. The process page shows the full program.
