Most UK bathrooms are small, have one sink cabinet at best, and — if you’re renting — you can’t drill the tiles. These fixes use the space above, beside and behind things instead of the floor.
Short on time? Our quick picks
- Best overall: Over-the-toilet shelving unit
- Best for renters: Adhesive shower shelves (no drilling)
- Best for tiny gaps: Slim rolling storage trolley
1. Over-the-toilet shelving unit
The wall above the toilet is the biggest unused space in most bathrooms. A freestanding frame (VASAGLE and SONGMICS both make popular ones) adds three shelves with no drilling.
2. Adhesive shower shelves (no drilling)
Stick-on stainless or aluminium caddies get bottles off the bath edge and shower floor. Renter-friendly and they come off cleanly with a hairdryer.
3. Slim rolling storage trolley
A 12–15 cm wide trolley slides into the gap between the toilet and the wall, or beside the washing machine. Perfect for toilet rolls and cleaning spray.
4. Two-tier under-sink organiser
Doubles the usable space under the basin and works around the pipe. Pull-out drawers mean nothing gets lost at the back.
5. Over-door towel hooks
Five or six hooks on the back of the door hold towels and robes — and free the radiator for actually drying things.
6. Clear stackable drawer organisers
For the vanity drawer or a shelf: skincare, make-up and first-aid bits each get a lane instead of rolling around together.
7. Toilet roll holder with storage
A freestanding holder that stores three or four spare rolls in its stem — one item doing two jobs.
Renting? Stick to these
Numbers 1, 3, 4, 5 and 7 need no fixings at all, and the adhesive shelves (2) come off without damage. That’s a full bathroom refresh without touching your deposit.
What to check before you buy
- Measure the toilet. An over-the-toilet frame has to clear the cistern and the flush button. Note the cistern’s width and height and how close it sits to the side wall.
- Measure the gaps. A slim trolley needs a gap a couple of centimetres wider than the trolley itself so it rolls in and out freely.
- Check the door. Over-door hooks need a small gap at the top of the door. If the door is a tight fit in its frame, the hooks can stop it closing.
- Choose materials that cope with damp. Bathrooms are humid, so look for stainless steel, aluminium, plastic or sealed bamboo rather than untreated metal or bare wood.
Getting adhesive fittings to stay up
Stick-on shelves and hooks usually fail for the same few reasons. Clean the tile with rubbing alcohol or a degreasing cleaner and let it dry completely. Stick to the flat face of a smooth tile, not across a grout line or onto textured tiles. Press firmly for as long as the instructions say, then leave it unloaded, usually for around 24 hours, before adding bottles. Stay within the stated weight limit, and remember that full shampoo bottles are heavier than they look.
Common questions
Can I use suction cups instead?
Suction only works on perfectly smooth, non-porous surfaces such as glass or glossy tiles, and it tends to let go over time as the temperature and humidity change. Adhesive pads are more reliable for anything that holds weight.
How do I take adhesive shelves off when I move out?
Warm the pad with a hairdryer for a minute or two to soften the glue, then slide dental floss behind it and work it downwards. Rub off any residue with your thumb or a little cleaner. Go slowly, and do not lever the shelf off with a tool, which can chip the tile.
Where do towels go if there is no rail?
Over-door hooks are the simplest answer. Hang towels spread out rather than bunched up so they dry between uses, and open the window or run the extractor fan after showers.
How do I stop a small bathroom looking cluttered?
Keep the surfaces around the basin and bath as empty as you can, and store by how often you use things: daily items at eye level, spares and cleaning products low down or behind a door. Matching baskets hide the visual noise of mixed packaging.
