Shower Tile Installation Wollongong — Waterproof, Precise and Built to Last

Floor tiles in a shower have to meet the minimum wet area slip rating under AS 4586. Doesn’t matter how good a tile looks on the showroom wall — if it doesn’t hit that rating for a wet shower floor, we can’t put it down, simple as that.

Large format tiles on shower walls mean fewer grout lines, fewer spots for water to get in, and an easier clean. Mosaics on shower floors give you natural grip underfoot, which is great, but you’re signing up for a lot more grout to maintain over the years.

A shower’s wet near enough every day of the year, so the grout’s gotta cope with that. We’ll talk you through epoxy versus cement grout for your shower specifically — one holds up to constant moisture a lot better, and it’s worth understanding why before you decide.

Niches Get Waterproofed on Their Own: A recessed niche is its own little waterproofing job inside the bigger one. It needs to be sealed individually before any tile goes near it — that’s one of the most common spots we see fail in showers tiled by someone working outside their depth.

Planned Into the Grid, Not Added After: We work out where niches, feature strips and contrasting floor tiles sit before we start setting tiles, so everything lines up with the overall grid.

We Test Before We Touch Anything: We tap over the existing tiles checking for hollow or lifting spots, which usually means the adhesive or the waterproofing underneath’s already failed. We’ll also check the grout’s condition and find out if the membrane underneath is still doing its job.

Tiling Over a Failed Membrane Isn’t a Fix: If that waterproofing’s gone, tiling straight over it isn’t a repair — it’s just putting the real problem off for a year or two while it gets more expensive underneath.

For a standard shower in an older Corrimal or Bulli home, I’m usually looking at three to five days once demolition’s done, depending on how much waterproofing prep is needed. Niches, feature strips or a full bathroom reno running alongside it can push that out a bit longer. I’ll always give you a proper timeline once I’ve seen the space, not a guess off the phone.

Once your new shower’s tiled, waterproofed and sealed, it needs a few days to cure properly before anyone steps in it, so no shortcuts there even if you’re keen to use it. If you’ve only got the one bathroom, like a lot of the older Thirroul and Dapto homes I work in, we’ll talk through a plan so you’re not stuck without a shower for the whole job. It’s a question worth raising with me upfront, not halfway through.

Straight tile replacement or retiling generally doesn’t need council sign-off, but if we’re moving plumbing, changing the shower’s footprint, or it’s part of a bigger structural reno, that’s a different conversation. I’ll flag it early if your job falls into that second category. Best to ask me directly once I know the scope, rather than assume either way.

Nine times out of ten in the older fibro and brick homes around here, that’s a ventilation issue combined with grout that’s past its best or a waterproofing membrane that’s starting to give up underneath. Mould on the surface is easy to wipe off, but it’s usually telling you something’s failing behind it. Worth getting it looked at properly rather than just bleaching it back every few months.

A shower’s wet constantly, copping steam and temperature changes all day, while the rest of your bathroom floor or walls dry out between uses. That means tighter waterproofing standards, stricter slip ratings on the floor, and a lot more precision around niches and corners inside the shower itself. I treat the two as completely different jobs, because they genuinely are.

Tiles themselves don’t crack from humidity, but grout and silicone can fail faster in a salty, humid coastal climate like ours if the wrong products were used or it wasn’t sealed properly the first time. That’s why I use grout and silicone rated for constant moisture rather than whatever’s cheapest. It’s a small cost upfront that saves you a much bigger headache a few years down the track.
