Small Bathroom Ideas: Design Tips for Compact Spaces
How to Maximize a Small Bathroom
A small bathroom (under 6 sqm) needs smart design choices to feel comfortable and functional. The right fixtures, tile layout, and storage solutions can make a compact bathroom feel twice its size. This guide covers proven strategies for small bathroom renovations.
Space-Saving Fixtures Comparison
| Standard Fixture | Space-Saving Alternative | Space Saved | Cost Difference |
|---|---|---|---|
| Pedestal basin (550mm) | Wall-mounted basin (450mm) | 100mm depth + floor space | +EUR 20-50 |
| Close-coupled toilet | Wall-hung toilet | 200mm depth + floor visible | +EUR 100-300 |
| Hinged shower door | Sliding shower door | 600mm swing clearance | +EUR 30-80 |
| Standard bath (1700mm) | Short bath (1400mm) | 300mm length | -EUR 0-50 |
| Freestanding vanity | Floating vanity | Floor space visible | +EUR 50-100 |
| Standard radiator | Heated towel rail | 50mm depth | +EUR 0-50 |
The biggest single improvement is switching from a bath to a walk-in shower. This frees up 0.5-1.0 sqm of usable floor space and eliminates the visual bulk of a bath panel.
Small Bathroom Layouts
| Bathroom Size | Recommended Layout | Fits |
|---|---|---|
| 1.5 x 2.0 m (3 sqm) | Shower, toilet, corner basin in L-shape | Cloakroom/en-suite |
| 1.8 x 2.4 m (4.3 sqm) | Shower, toilet, vanity basin along one wall | Small family bathroom |
| 2.0 x 2.5 m (5 sqm) | Shower + short bath, toilet, basin | Compact family bathroom |
| 2.0 x 3.0 m (6 sqm) | Full bath, separate shower, toilet, vanity | Standard bathroom |
In layouts under 4 sqm, place the shower opposite the door so it is the first thing you see — this creates an impression of depth. Keep the toilet beside the door where it is less visible.
Tile Strategies for Small Spaces
| Strategy | Why It Works | Cost Impact |
|---|---|---|
| Large format tiles (30x60cm+) | Fewer grout lines = less visual clutter | +10% (more cuts/waste) |
| Same tile floor to ceiling | Blurs boundaries, fewer transitions | +20-30% more tiles |
| Light colours (white, cream, grey) | Reflects light, opens up space | EUR 0 difference |
| Continuous floor-to-shower tile | No visual barrier at shower entry | EUR 0 (same tiles) |
| Vertical rectangular tiles | Draws eye upward, adds height | EUR 0 difference |
| Glass mosaic accent strip | Reflective, adds depth without bulk | +EUR 20-50 for strip |
Storage Solutions That Do Not Take Floor Space
Recessed shower niches are the best storage solution for small bathrooms — they are built into the wall during tiling and cost nothing beyond the extra tile cuts. Standard niche sizes are 300x300mm (single) or 300x600mm (double).
A mirror cabinet above the basin provides hidden storage and serves as the bathroom mirror — two functions in one fixture. Choose a recessed cabinet (built into the wall cavity) if the wall depth allows.
Floating shelves above the toilet use otherwise wasted wall space. Keep them shallow (100-150mm deep) to avoid head-bumping. Use our bathroom renovation calculator to estimate the tiles and materials for your small bathroom, then compare costs with the bathroom renovation cost calculator.
Optical Tricks to Enlarge a Small Bathroom
| Trick | Effect | Difficulty |
|---|---|---|
| Large mirror (wall-to-wall above basin) | Doubles visual width | Easy — mount with mirror adhesive |
| Frameless glass shower panel | No visual barrier, continuous sightline | Moderate — needs precise fitting |
| Consistent grout colour (match tile) | Grout lines disappear, surfaces look continuous | Easy — colour-match at purchase |
| LED strip under floating vanity | Floor glows, vanity appears to float | Easy — stick-on LED strips |
| Pocket door (no swing) | Saves 0.5 sqm of door swing clearance | Hard — structural modification |
The most impactful change is a large mirror combined with good lighting. A wall-to-wall mirror above the basin costs EUR 50-150 and visually doubles the room width. If you are renovating the kitchen too, our kitchen renovation calculator helps plan that project. For painting other rooms in the house, use the paint calculator.
