If you’re working with a compact layout, the good news is there are plenty of bathtub options designed specifically for smaller spaces. This guide breaks down the best types of small bathtubs for compact bathrooms, how to choose one that fits your layout, and smart design ideas to help you save space without compromising on comfort or style.

What Size Bath Do I Need for a Small Bathroom?

The sweet spot for a small bathroom is usually a bath between 1300mm and 1500mm long. That’s enough space to stretch out without crowding the rest of your layout. Here’s a quick size guide to help:

• 1300mm–1400mm: Ideal for very compact bathrooms or second bathrooms.
• 1500mm: The most common compact bath size. You’ll find a huge range in this size, from freestanding to corner tubs to inset bathtubs.
• Above 1600mm: You’ll usually need a larger bathroom to fit this comfortably, especially if you’re adding a vanity or separate shower.

Pro tip: Measure not just your available floor space, but also the clearance around doors, windows, and other fixtures. And don’t forget to check if you’re working with left-hand or right-hand plumbing for corner or back-to-wall baths.

How to Choose a Bath for Your Small Bathroom

Picking the right bath means balancing size, function and style. Here’s how to get it right for your space.

Start with accurate measurements

Don’t just go by overall bathroom size. Measure your available wall space, and take into account door swings, window placement, vanities and toilets. You want enough clearance to move comfortably.

Choose a layout that works with your plumbing

If your plumbing is already set, it’s easier (and cheaper) to pick a bath that suits the existing location. Back-to-wall and corner bathtubs are great for making the most of tight layouts.

Pick materials based on use

Acrylic baths are lightweight and easy to install. If you’re after a luxe, sculptural feel, consider a solid surface bath. These are heavier, more durable and feel great to touch.

Think about depth, not just length

You don't need a long bath to get a good soak. Look for designs with a deeper interior, especially in the freestanding or inset bath ranges. Compact outside, roomy inside.

Space-Saving Bath Design Ideas

Making a small bathroom work is all about smart design choices. Here are a few that make a big difference.

Stick to the walls

Back to wall and corner baths free up the middle of the room so everything feels more open and less cluttered.

Swap curtains for screens

A fixed or folding glass screen makes the room feel bigger and brighter. Curtains can visually cut the room in half.

Use wall-mounted tapware

Wall mixers and spouts free up ledge space and create a cleaner look around the bath. They’re especially handy in tight layouts.

Combine bath and shower

If you don’t have space for both, choose a bath that can do double duty. Add a hand-held shower or a dual shower set for more flexibility.

4 Small Bath Installation Tips and Mistakes to Avoid

There’s not much room for error in a small bathroom, so the install needs to be thoughtful from the start.

Watch your clearances

Make sure the bath won’t block doors, drawers or walkways. Even an extra five centimetres can make a difference in how the space feels.

Don’t box in the plumbing

Leave access to your bath waste and taps wherever possible. It might not seem like a big deal until something needs fixing.

Know when to call in a pro

Small spaces are harder to work in, especially when you’re moving plumbing or dealing with tricky drainage. A licensed plumber is worth it here.

Keep the floor clear and clean

Concealed floor wastes give you a sleek, seamless finish that’s easy to clean and less distracting in a small space.

Styling and Storage Solutions for Small Bathrooms

Once the bath is in, it’s time to make the rest of the space feel good to live in.

Go wall-hung where you can

A wall-hung vanity or basin creates breathing room. You can see more of the floor and it makes the whole room feel lighter.

Double up with mirror storage

Mirror cabinets give you two functions in one without adding bulk. Great for storing essentials you don’t want on display.

Add shelving in the right places

Use wall-mounted shelves or built-in niches to keep products off the floor. Recessed shelves in the shower or above the bath work well in tight spots.

Let light do the heavy lifting

Use soft overhead light and add an LED mirror to brighten up your routine. Glossy surfaces and pale finishes help reflect light too.

Baths for Small Bathrooms FAQs

What’s the difference between freestanding and back to wall baths?

Freestanding baths are finished on all sides and can sit anywhere in the room. Back to wall baths have the freestanding look but sit flush against a wall, saving space and making cleaning easier. 

Can I install a bath in a powder room?

It’s rare, but not impossible. You’d need plumbing in place and enough room for a small bath, usually 1300mm or less. If not, consider a statement basin instead.

Do all baths come with overflow drains?

No. Some baths include an overflow as standard, but others don’t. Always check the specs before buying and speak with your plumber about your preferred setup.

Are solid surface baths worth it?

Solid surface baths offer a premium look and feel. They’re heavier, more durable and usually matte in finish. If you’re after a modern, architectural statement piece, they’re a great choice. 

Can I use a freestanding bath as a shower too?

Yes, as long as the bath has a flat, stable base and is paired with the right screen and shower head. A hand-held or dual set gives you extra flexibility.

What’s the easiest bath to clean?

Back to wall or inset baths are typically the easiest. They sit flush against tiles so there are fewer hard-to-reach areas behind or underneath.

Can I install a bath on a timber floor?

Yes, but it’s important to check the weight of the bath and whether the floor needs reinforcing. This is especially relevant for solid surface baths, which can be much heavier than acrylic.
