5 Small Bathroom + Washer/Dryer Layouts: Creative layouts and real-world tips for fitting a washer and dryer into a compact bathroom

I once had a client who insisted their bathroom must fit a washer, dryer, bathtub, and a plant big enough to hide their in-laws during visits — I laughed, then sketched three versions before we found the one that actually worked. Small bathrooms force you to be clever; they’re where I learned to stack functions, exploit vertical space, and treat every centimeter like gold.

1. Stack and tuck: Vertical washer-dryer column

My go-to for narrow bathrooms is a stacked washer-dryer in a recessed niche. It keeps the floor clear and leaves room for a slim vanity or a wall-hung toilet. Advantages: saves floor area and simplifies plumbing. Challenge: louder vibration can transfer to cabinetry, so add anti-vibration pads and allow 5–10 cm clearance for ventilation. For planning this tight fit, I sometimes refer clients to a room planner case to visualize the column within the niche.

2. Under-sink washer: Dual-purpose vanity

I designed an apartment where the washer lived under a custom vanity drawer — the sink sits slightly offset to keep hoses out of sight. Pros: integrates laundry into the daily routine and hides machines behind cabinetry. Cons: less storage under the basin and trickier access for maintenance — design removable panels and slide-out trays to make servicing painless.

3. Alcove stack with shower beside

When the shower can share a wet-wall, placing a stacked washer-dryer in an alcove next to it uses existing plumbing lines and minimizes extra pipe runs. It’s efficient and often cheaper. Watch out for moisture: use proper sealing, a waterproof door, and a small extractor fan to keep the machine dry between cycles.

4. Closet-style laundry in bathroom entrance

I once converted the entry recess into a shallow laundry closet with bi-fold doors — daytime you close it and the bathroom feels spacious; laundry day you open it up. Benefit: hides clutter and keeps machines out of sight. Drawbacks: requires enough depth (about 60–70 cm) and careful door swing planning; consider a pocket door to save that last bit of space.

5. Side-by-side mini units under a counter

If width allows, two slim front-load machines under a shared countertop become a folding station and built-in bench. This creates a hospitality vibe in a small footprint. The trade-off is reduced bathroom cabinetry and possibly less circulation space, so pair with wall-hung fixtures and a floating shelf to keep the room airy.

Tips 1:

Practical tips from my projects: always plan ventilation first, designate an accessible service panel, and measure twice — appliances come in slightly different depths. Don’t forget electrical placement; most small bathrooms need a dedicated circuit and a GFCI-protected outlet.

FAQ

Q: What’s the minimum bathroom size to fit a washer and dryer?

A: You can fit a stacked washer-dryer in as little as 1.5–2 square meters if you use a recessed niche and wall-hung fixtures. Precise dimensions depend on machine depth and door clearances.

Q: Can I put a washer and dryer in a bathroom without extra ventilation?

A: It’s not recommended — bathrooms are humid and machines add moisture. Install an extractor fan and ensure dryer venting or use a ventless condenser dryer with careful humidity control.

Q: Are ventless dryers a good option for small bathrooms?

A: Yes, ventless dryers save exterior venting and are easier to install in tight spaces, though they may run longer and slightly warmer than vented units.

Q: How do I hide the washer and dryer aesthetically?

A: Use full-height doors, integrated cabinetry, or a curtain to conceal machines. Materials that match the vanity create a seamless look and feel.

Q: What electrical requirements should I consider?

A: Many washers run on standard 120V circuits, but some dryers need 240V. Always consult a licensed electrician to identify the correct circuit and GFCI protection.

Q: Any tips for balancing plumbing placement?

A: Align the washer near existing water supply and drain lines to reduce cost. Shared wet-walls are your friend and cut down on pipe runs.

Q: How do I prevent mold around machines in a small bathroom?

A: Keep the area well-ventilated, use mildew-resistant finishes, run the extractor fan during and after laundry, and occasionally leave the washer door cracked to air out. The CDC recommends proper ventilation for damp spaces (cdc.gov).

Q: Where can I visualize multiple layout options before renovating?

A: Using an online floor planner helps test configurations and clearances quickly — it saved several of my projects from costly mistakes.
