Bathrooms are the hostile environment of the blind world: humidity cycles, direct splashes, condensation pooling on sills, and tiles where your fixings need to go. Most “which blind?” mistakes in bathrooms aren’t style errors — they’re material errors that show up six months later as warp, rust spots and mould.
Materials: what survives
Safe choices
- Faux wood (PVC) venetians — the bathroom default. Wipeable, waterproof, and they give slat-level privacy control, which matters in a room where privacy is the whole point.
- PVC or treated-polyester rollers — sold as “moisture-resistant” or “bathroom” ranges. Simple, cheap, easy to clean. Check the product listing actually says moisture-resistant; a standard fabric roller is not the same thing.
- Aluminium venetians — moisture-proof and the budget option, if a little clinical.
Risky choices
- Real wood venetians — humidity swells and warps timber and lifts finishes. Some ranges are sold for “high humidity” use; even then, faux wood is the safer money.
- Fabric romans and unlined textiles — absorbent fabric + steam = mould speckle and drooping folds. If the bathroom is large, well ventilated and the blind sits far from the shower, you can get away with it — that’s a gamble, not a plan.
- Day and night blinds — many cope, but the double layer dries slowly; reserve them for well-ventilated bathrooms.
Privacy, since that’s the point
- Slatted blinds win daytime privacy: tilt venetian slats up and light comes in while sightlines from outside are blocked.
- Frosted glass already does privacy — a blind on frosted glass is for night silhouettes, darkness and warmth. Decide which of those you actually need before spending.
- At night, sheers and open slats reveal more than people think. If the window faces neighbours, choose something that closes fully.
Fitting in a bathroom
The general fitting walkthrough applies, with two bathroom-specific hazards:
- Tiles. Drilling tiles needs a tile bit, masking tape, hammer mode off until through the glaze — and nerve. A cracked tile is the most expensive mistake available in this room. If the reveal is fully tiled and you’ve never drilled tile, this is a genuinely good place for a fitting-only professional.
- Avoid drilling near hidden pipework. Pipes run to basins, showers and radiators inside bathroom walls more than anywhere else. A cheap pipe/cable detector is worth it here.
No-drill routes work well in bathrooms: Perfect Fit-style frames that clip to uPVC beading, and tension/twist-fit rollers inside the recess, avoid both tiles and pipes entirely — worth a look for rentals especially.
Whatever you fit, use rust-resistant fixings (the plated screws in the box are usually fine; bare steel isn’t), and fit the chain tensioner as always — child safety rules don’t pause at the bathroom door.
The quick answer
Faux wood venetian if you want adjustable privacy; moisture-resistant roller if you want simple and cheap. Measure exactly as in the measuring guide — steamy rooms don’t change the numbers, just the materials.
Frequently asked questions
What's the best blind for a bathroom?
Faux wood (PVC) venetians and moisture-resistant polyester or PVC rollers are the two safe defaults: both shrug off humidity and wipe clean. Aluminium venetians also cope well. The choice between them is really about whether you want adjustable slats or a simple clean roll.
Which blinds should I avoid in a bathroom?
Real wood venetians (warping and finish damage), fabric romans (they hold moisture and mould), and unlined natural-fibre anything. If your heart is set on a soft look, keep the extractor fan serious and accept you're trading lifespan for style.
Do I need a blind if the glass is frosted?
Not for privacy in daylight — frosting does that job. People add one anyway for night-time silhouettes against the light, for darkness, for warmth, or for looks. If none of those apply, save the money.
