5 Toilet Bowl Ideas for Small Spaces: Smart, space-saving toilet bowl solutions from a seasoned interior designer

Once I tried squeezing a full-size toilet, a shower and a washing machine into a space the size of a walk-in closet — the client wanted everything because “why not?” I learned the hard way that small space can inspire big ideas, and sometimes a tiny swap saves the whole project. Here I share five practical inspirations (and the little trade-offs) that I use on real jobs, plus a few space-saving layout tips I swear by: space-saving layout tips.

1. Wall-hung toilets for visual and floor freedom

I love wall-hung toilets because they lift the bowl off the floor and make a tiny bathroom feel airier. The upside is easier floor cleaning and a sleeker profile; the downside is a higher upfront cost and a required carrier frame behind the wall. If your budget allows and the wall can take the load, it’s one of the fastest ways to make a bathroom feel larger.

2. Corner and compact corner bowls

When the room shape is awkward, a corner toilet turns wasted angles into usable fixtures. It’s not as comfortable as a standard bowl for long sittings, but it’s brilliant when every centimeter counts. I used this in a city studio where we also reclaimed space for a shower — a small trade for big layout gains.

3. Narrow elongated bowls — comfort without breadth

A narrow elongated bowl gives better ergonomics than a round bowl but keeps the footprint slim. It’s a favorite when clients want comfort but must avoid a bulky silhouette. Installation is straightforward, though check seat availability for the model you choose — not all seats are universal.

4. Integrated sink-toilet and tank-top sinks

Two-in-one options — like a sink integrated over the cistern or tank-top sinks — are clever for micro-bathrooms and save plumbing runs. They reuse greywater for flushing in some models, which helps with water efficiency, but you’ll sacrifice some sink space and styling choice. For visualizing how these combos fit, try visualizing the layout in 3D before you buy.

5. Smart seats, compact controls, and door moves

Sometimes the cheapest win is a slim bidet seat or relocating the door to a pocket or sliding variant so the toilet area breathes. Smart seats add function without adding bulk; sliding doors reclaim swing radius but add construction cost. For tricky plans I often lean on AI-assisted layouts to test multiple orientations fast.

FAQ

Q1: What toilet bowl type works best for very small bathrooms?

A1: Wall-hung and compact elongated bowls are usually best — they reduce visual bulk and reclaim floor space. If structural changes aren’t possible, choose a narrow-profile round or corner bowl.

Q2: Are wall-hung toilets suitable for rental apartments?

A2: They can be, but installation often requires a carrier frame inside the wall and may not be allowed in some leases. Always check landlord approvals and structural limits before altering walls.

Q3: How much clearance do I need in front of a toilet?

A3: A common guideline is at least 21 inches (about 53 cm) of clear space in front of the bowl for comfortable use, though local codes can vary. I always measure full circulation, not just the fixture footprint.

Q4: Are compact elongated bowls better than round bowls?

A4: Compact elongated bowls offer a balance of comfort and reduced depth, giving better ergonomics than round bowls without taking as much room as full elongated models.

Q5: Can I put a bidet seat on a compact toilet?

A5: Often yes, but check the bowl’s shape and the seat’s compatibility. Some compact bowls need specifically designed seats, so verify dimensions before ordering.

Q6: How much water do water-efficient toilets use?

A6: Modern WaterSense-certified toilets typically use 1.28 gallons per flush or less, which saves significant water compared with older 3.5–7 gpf models (source: EPA WaterSense, https://www.epa.gov/watersense).

Q7: Wall-hung or floor-mounted — which should I choose?

A7: Wall-hung wins on visuals and cleaning; floor-mounted is cheaper and simpler to install. Your choice depends on budget, wall structure, and whether you plan a full renovation.

Q8: Do I need a plumber for a toilet swap?

A8: For like-for-like replacements you might manage if you’re handy, but changes to footprint, carrier frames, or water lines need a licensed plumber. I recommend a pro to avoid leaks and code issues.
