\"Bathroom
Bathroom storage is a geometry problem before it is a style problem.<\/figcaption><\/figure>\n

Bathroom storage gets sold on looks: bamboo, matte black, ribbed glass, brushed brass. None of that tells you whether the thing will hold a litre of shampoo at shoulder height without pulling the tiles off the wall. This piece is the other half – the numbers that decide whether a shelf gets used every day or becomes the place where half-empty bottles go to die. Everything below is either a dimension you can check with a tape measure or a physical fact you can check with a kitchen jug.<\/p>\n

1. A corner is a triangle, not a shelf<\/h2>\n

Trace a corner along both walls and you get 90 degrees and a triangle in between. With 40 cm of clear wall on each side – a common amount beside a basin – that triangle encloses roughly 0.08 square metres of floor. Two corners give you 0.16. A single 60 by 30 cm shelf gives 0.18, so a pair of corners is worth about one shelf, except the corners already exist and cost nothing.<\/p>\n

The catch is shape. A fixed box pushed into a corner has a back corner you cannot reach, and the deeper the unit the bigger that dead zone: at 30 cm deep the last 8-10 cm is storage you can see and not touch. That is the honest argument for a rotating corner unit – it turns the unreachable back into the front of the shelf for the two seconds you need it, then gets out of the way of the shower door.<\/p>\n

2. The only height band that matters is 90-150 cm<\/h2>\n

Between roughly 90 cm and 150 cm above the finished floor, a shelf sits in the band most adults reach without bending or climbing. Above 170 cm you need a step for anything at the back; below 60 cm you are crouching, and crouching shelves fill with things nobody uses. This is why wall-mounted storage beats a floor caddy more often than people expect: on the wall you choose the height, and on the floor you inherit whatever height the designer picked.<\/p>\n

Two placement rules follow. Beside a basin, mount the bottom edge of the unit at 95-105 cm so the top tier lands inside the comfortable band. Inside a shower, mount it at 110-120 cm, which keeps the lower bottles clear of the spray pattern at hip height while staying reachable with a wet hand.<\/p>\n

3. Swinging beats reaching: 20-30 cm<\/h2>\n

A fixed corner shelf gives you whatever your arm can reach around. A rotating one adds the distance it travels: typically 20-30 cm at the outer edge. That does not sound like much until you are standing in a 75 cm wide shower with a bottle in one hand and a wet floor underfoot. The number to check before buying is swing clearance – the unit needs that 20-30 cm clear of the shower door, the towel rail and your elbow, or it becomes a fixed shelf that also rattles.<\/p>\n

4. Water is the heaviest thing you store<\/h2>\n

Storage is judged by what it holds when full, not when empty. A one-litre shampoo bottle weighs about 1.05 kg. Five of them, plus conditioner, body wash and a razor, is a 6-8 kg load on a shelf that might be fixed with two screws or a strip of adhesive. Adhesive plates on smooth tiles typically hold 3-5 kg when new, and less once the tile is damp or the surface is textured. So the rule is blunt: under 5 kg adhesive can be fine; over 5 kg, use screws and plugs into something solid.<\/p>\n

On a rotating unit, keep the heavy bottles at the wall end. The outer edge is a lever arm, and every extra 10 cm from the pivot multiplies the pull on the mount – which is exactly where cheap fixings fail first.<\/p>\n

5. Spray reaches 1.2 m, so drainage beats material<\/h2>\n

A shower head at two metres throws water in a cone that wets a band roughly 1.0-1.3 m up the opposite wall. Anything mounted inside that band gets soaked every time somebody showers, which is why drainage matters more than the label on the box. A caddy with open wire or slot drainage dries in minutes. A flat tray holds a 2-3 mm film of water around the bottle bases, and that film is what becomes the pink-orange biofilm people blame on hard water. Tip the tray out weekly, or buy the version with holes in the bottom.<\/p>\n

6. Humidity: 70-90%, then a 20-40 minute cooldown<\/h2>\n

During a shower, bathroom humidity climbs into the 70-90% relative humidity range; with an extractor fan running it falls back towards the rest of the house in roughly 20-40 minutes. Two practical consequences. First, plastic and powder-coated steel shrug this off, uncoated mild steel does not, and 304 stainless survives where 201-grade stainless starts to spot. Second, never seal a damp caddy flat against the wall: a few millimetres of air gap behind the unit is the difference between a dry wall and a black line of mould six months later.<\/p>\n
