Shower Protection & Treatments

Why shower protection matters

Showers are exposed to pressurised water, steam and soaps several times every day. Without the right protection, water can seep through grout lines, damage substrates, and create hidden mould colonies. In Australia, rectifying a failed wet area can cost tens of thousands of dollars and often requires removing the entire enclosure. Investing in quality shower protection & treatments at the start is far cheaper than remedial work later on.

Types of shower protection products

• Penetrating sealers – Nano-sized particles soak into porous tiles and grout, forming an invisible barrier that repels water and oils while allowing vapour to escape.
• Film-forming sealers – Acrylic, epoxy or polyurethane coatings create a surface layer that blocks moisture and makes cleaning easier. Ideal for high-traffic commercial bathrooms.
• Glass treatments – Silica-based sprays and wipes bond with glass to minimise mineral staining and soap scum, cutting cleaning time by up to 90 %.
• Grout recolourants & protectants – Two-in-one products restore discoloured grout and seal it in a single application.
• Mould-inhibiting cleaners – Regular use maintains the performance of the primary sealer and safeguards indoor air quality.

Choosing the right solution

1. Identify your surface materials

Natural stone, porcelain, terrazzo and glass each respond differently to chemicals. A penetrating sealer formulated for travertine may slightly darken marble, while a fluoropolymer glass coating is useless on ceramic tile. Always match the product to your surface and test on an inconspicuous area.

2. Assess exposure levels

Master ensuites used daily need heavier-duty protection than a seldom-used guest bathroom. In frameless walk-in designs, overspray reaches floors and adjacent walls, so look for broad-spectrum sealers rated for horizontal and vertical surfaces.

3. Verify compliance

Under the National Construction Code and AS 3740-2021 Waterproofing of domestic wet areas, wet areas must be waterproofed to specific heights and penetrations. While many treatments are considered maintenance products rather than structural waterproofing, choosing solutions tested to Australian standards gives extra peace of mind.

4. Understand application methods

Brush-on products are DIY-friendly; two-part epoxies often need a professional. Factor in ventilation, cure time and temperature range. If you are coordinating a full renovation, schedule sealing before installing shower trays & drains, shower doors or bath & shower screens to avoid contamination.

Maintenance tips

• Wipe glass after each use with a squeegee or microfibre cloth to prevent mineral build-up.
• Use pH-neutral cleaners; acidic products can strip some sealers.
• Reapply penetrating sealers every 2–5 years, or as recommended by the manufacturer.
• Inspect silicone joints when cleaning shelves or fitting new shower shelves.
• Upgrade worn fittings with compatible shower accessories to keep the enclosure watertight.

Cost guide

Expect to pay $80–$200 for a premium 1 L penetrating sealer that covers 5–15 m², and $60–$150 for a glass treatment kit covering an average cubicle. Professional application labour ranges from $35–$60 per square metre, depending on location and surface complexity. Comparing quotes on ArchiPro lets you balance upfront cost with long-term durability.

Environmental considerations

Low-VOC water-based treatments are now common and emit fewer odours during curing. Look for GreenTag or GECA certification if sustainability is a priority, and dispose of solvent residue at approved collection centres rather than down the drain.
