When it comes to designing small bathrooms with a shower and tub, creativity is key. With limited square footage, it might seem impossible to combine both bathing and showering functionalities. However, through strategic planning and smart layout decisions, you can create a full bathroom that feels spacious, elegant, and entirely functional.

Whether you’re undertaking a bathroom remodel or planning a new build, this guide explores the best floor plans for small bathrooms that seamlessly fit a shower-tub combo. We’ll also share actionable layout ideas, design tips, and space-saving fixtures to help you make the most of your bathroom.

Why Combine a Shower and Tub in Small Bathrooms?

 

Incorporating both a shower and a tub into a small bathroom layout may seem ambitious, but it can dramatically improve both the functionality and value of your home. Here’s why this combination works so well, especially in compact bathroom spaces:

• Maximizes Usability: Families often need a full bathroom that suits both quick daily routines and relaxing baths. A combined shower and tub provides flexibility, particularly for households with children or elderly members who prefer soaking.

• Improves Resale Value: A home with at least one bathroom that includes a tub is more marketable. Buyers often search for full bathrooms, and a tub-shower combo delivers exactly that in a space-efficient format.

• Space-Saving Elegance: A single unit takes up significantly less floor space than installing a separate shower stall and bathtub, making it ideal for urban apartments or older homes with smaller footprints.

• Ideal for Small Soaking Tubs: Many modern tubs are specifically designed for smaller rooms but still offer deep soaking capabilities, enhancing comfort without compromising layout.

• More Cost-Effective Plumbing: Combining the two units often means using a shared plumbing wall, simplifying construction and saving money on installation.

Now, let’s dive into the top-performing layout strategies that make small bathrooms with a shower and tub truly shine.

1. Classic Three-in-a-Row Layout: Efficient and Straightforward

This traditional layout places all fixtures—vanity, toilet, and combined tub/shower—along a single wall. It’s a layout often found in mid-century homes and remains popular due to its simplicity and cost-effectiveness.

Best Suited For:
• Bathrooms around 5’ x 8’ or 40 square feet
• Budget-conscious remodels with limited structural modifications

Key Advantages:
• Streamlined Plumbing: All fixtures aligned along one wall reduce installation complexity and expenses.
• Easily Fits Alcove Tubs: Standard tubs measuring 60″x30″ can nestle perfectly into a wall alcove, doubling as a soaking tub.
• Allows for a Double Vanity (Compact): If the wall length allows, you can fit a smaller double sink vanity, enhancing usability for couples.
• Great for Pocket Doors: Replacing a swinging door with a pocket door can free up several feet of usable space.
• Works Well with Frameless Glass: Installing a frameless glass shower screen enhances visibility and gives the illusion of a larger room.

Design Enhancements:
• Use light-colored wall tiles to reflect light and expand visual depth.
• Extend the shower wall tile to the ceiling to draw the eye upward.
• Add recessed shelving inside the shower wall to minimize clutter and maintain open space.

2. L-Shaped Bathroom Layout: Optimized for Awkward Spaces

The L-shaped layout is ideal for bathrooms that aren’t rectangular or need a touch of zoning for more privacy and functionality. By placing the vanity and toilet along one wall and the tub perpendicular on the other, the room feels more balanced and segmented.

Perfect For:
• Corner bathrooms
• Suites or en-suites where layout flexibility is needed
• Bathrooms that must fit into architectural constraints, such as attic or under-stair locations

Why It Works:
• Natural Wet and Dry Zones: Separates the wet zone (tub and shower) from the dry zone (vanity and toilet), which improves flow and cleanliness.
• Enhances Visual Space: By breaking up the layout into segments, the room avoids the tunnel effect that plagues narrow bathrooms.
• Better Privacy: The tub area can be tucked behind a partial wall or frosted divider for more privacy.
• Great for Tall Storage: Awkward corners can house linen towers or tall cabinets for towels and toiletries, maximizing vertical space.

Design Suggestions:
• Consider an L-shaped vanity or corner vanity to echo the layout and offer more counter space.
• Install a frameless corner shower screen above the tub to create an open look while containing water.
• Choose contrasting floor tiles between zones to delineate spaces.

3. Corner Tub with Shower Above: Maximize Every Square Inch

If you’re working with a very compact bathroom layout, integrating a corner tub with a shower above is one of the smartest strategies. These tubs are specifically crafted for small bathrooms with tub needs, offering functionality without occupying valuable wall or walking space.

Recommended For:
• Bathrooms under 45 square feet
• Diagonal wall spaces or under-window areas
• Secondary or guest bathrooms

Space Benefits:
• Utilizes Corners: Corners are often dead space. A corner tub makes that area functional without restricting movement.
• Creates Room for Larger Vanity: Because the tub doesn’t run parallel to the wall, that space can be reassigned to a wider vanity or additional cabinetry.
• Design Flexibility: Corner tubs come in oval, angled, and rounded shapes, giving more aesthetic options.
• Improved Mobility: With fewer obstacles, it creates a more navigable layout for smaller floor areas.

Implementation Ideas:
• Install a glass corner shower screen above the tub instead of a full enclosure to minimize visual weight.
• Use neutral flooring and wall finishes to reduce visual segmentation.
• Add a wall niche above the tub for shampoos and bath salts.

4. Split Layout with Toilet Niche: Privacy and Functionality

 

The split layout is one of the most practical solutions for households that need a shared bathroom space without compromising comfort or privacy. This design separates the toilet area from the tub and vanity, usually through a partial wall, frosted glass divider, or a pocket door.

Ideal For:
• Small families or roommates
• Bathrooms around 6’ x 8’ (48 square feet)
• Remodels prioritizing both function and personal space

Layout Features:
• Toilet tucked in a niche: The commode is discreetly positioned behind a short dividing wall or enclosure, which enhances privacy.
• Shared access with minimal traffic conflict: One person can shower while another uses the toilet or sink.
• Maximizes floor plan functionality: Efficient use of space allows the inclusion of more counter space or storage options.

Recommended Design Elements:
• Use a half wall between the toilet and vanity for an open look that still offers a visual barrier.
• Install a ceiling-height mirror above the vanity to stretch perceived height.
• Incorporate a slim storage unit between the tub and toilet for added utility.

Smart Tip: Try installing a frosted glass sliding door between zones to allow natural light while preserving privacy.

5. Wet Room Concept: A Modern Twist for Small Spaces

Wet rooms are the epitome of modern, minimalist bathroom design. By eliminating physical barriers between the tub and shower, you unlock maximum usability and visual openness in even the smallest bathrooms.

Best For:
• Contemporary designs
• Bathrooms as small as 6’ x 6’
• Homeowners prioritizing seamless layouts and easy maintenance

Advantages:
• Barrier-Free Design: The tub and shower are housed within one waterproofed area, enhancing mobility and accessibility.
• Luxury Look: Frameless glass, oversized wall tiles, and recessed lighting can give the space a master bathroom feel.
• Ease of Cleaning: Without thresholds or dividers, mopping and sanitizing the space becomes more straightforward.

Essential Requirements:
• Proper Drainage: A centrally placed linear drain or floor slope ensures that water doesn’t spread throughout the room.
• Full Waterproofing: Floor, walls, and joints must be thoroughly sealed using waterproof membranes.
• Slip-Resistant Flooring: Choose textured or matte-finish tiles to prevent slipping in wet areas.

Additional Touches:
• Install built-in benches or seating near the tub for both aesthetics and functionality.
• Add heated floors for spa-like comfort during colder months.

Key Fixture Types for Small Bathrooms with Tub and Shower

Choosing the right fixtures can make or break the layout. Here are the most space-efficient options to consider:

• Freestanding or drop-in models under 60 inches
• Deep enough for immersive bathing without taking up wall space
• Great for wet room concepts or corner installations

2. Alcove Bathtubs with Overhead Showers

Perfect for the classic three-in-a-row or split layout.
• Fit snugly between three walls
• Budget-friendly and compact
• Easy to retrofit into existing floor plans

3. Corner Bathtubs

Use less floor space while adding style and functionality.
• Curved or angular shapes for optimized fit

Design Strategies to Maximize Your Small Bathroom Floor Plan

 

Regardless of your chosen layout, certain design principles can dramatically enhance the look and feel of a small bathroom. These tips apply universally to small bathrooms with a shower and tub:

• Light-Colored Tiles: Use soft tones like white, cream, or light grey for walls and floors to enhance brightness and openness.
• Mirrors: Install a full-wall or oversized mirror above the vanity to reflect light and expand visual dimensions.
• Floating Vanities: They expose more floor area, making the room appear less crowded and easier to clean.
• Frameless Glass Panels: Replace bulky shower curtains with clear glass screens to maintain visual continuity.
• Pocket Doors: Install sliding doors instead of hinged ones to free up square footage.
• Vertical Storage: Add wall-mounted shelves, medicine cabinets, or towel niches to use vertical space efficiently.
• Recessed Lighting: Brighten corners and eliminate shadows with LED pot lights or strip lighting.
