Why Choose a Tiny Tub for a Tiny House
Even in a compact home, having a bathtub can transform the way you live. Many people assume a shower is the only option in a small space, but that’s not always true. Here’s why more tiny house owners are choosing tiny tubs:
Benefits of Having a Tiny Tub
- Relaxation & Mental Health: A soak in warm water helps relieve stress, soothe sore muscles, and promote better sleep.
- Practical for Families & Pets: A small tub makes bathing children or pets much easier than using a shower stall.
- Adds Value & Appeal: A tiny tub can make your home more attractive to buyers or renters.
- Multi-Functional Use: Some designs allow dual use — for example, as a storage basin or laundry wash tub when not in use.
Tiny Tub vs. Shower: Which Is Better for Small Homes?
| Feature | Tiny Tub | Shower |
| Comfort | Excellent for soaking and relaxing | Faster, but less relaxing |
| Water Use | Slightly higher (varies by tub size) | Generally more water-efficient |
| Space Required | Needs careful layout planning | Easier to fit in tight corners |
| Maintenance | Easier to clean with fewer surfaces | Grout and glass can collect mildew |
| Aesthetic Appeal | Cozy, spa-like look | Modern and minimalistic |
While a shower might win on efficiency, the tiny tub often wins on comfort and character. For many, the tradeoff is worth it.
Space Planning: Measuring for a Tiny Tub
Before shopping for a tub, space planning is absolutely crucial. Even the most compact bathtub will feel overwhelming if it’s squeezed into an unplanned layout.
Here’s how to make sure your tiny house bathroom can accommodate a tub comfortably:
Step 1: Measure Available Floor Space
- Measure the length, width, and height of your bathroom area.
- Keep in mind you’ll need space for access and cleaning around the tub — ideally at least 2 feet of clearance on one side.
Step 2: Know Common Tiny Tub Dimensions
Tiny tubs come in a variety of compact sizes. Here’s a quick reference table:
| Tub Type | Typical Length | Width | Depth | Notes |
| Soaking Tub | 36–48 in | 24–30 in | 24–30 in | Deep enough for full immersion |
| Japanese Ofuro | 35–45 in | 25–30 in | 30+ in | Vertical design, minimal footprint |
| Corner Tub | 40–50 in (diagonal) | Varies | 18–24 in | Fits snugly in corners |
| Freestanding Mini Tub | 45–55 in | 27–32 in | 22–28 in | Aesthetic and versatile |
| Portable Tub | 30–40 in | 20–25 in | 20–25 in | Lightweight and mobile |
Step 3: Plan for Plumbing and Drainage
- Locate existing drain and water lines — moving them can add cost.
- For off-grid tiny houses, consider how you’ll manage water heating and greywater disposal.
Step 4: Think About Weight and Balance
Water is heavy — about 8.34 pounds per gallon. A 40-gallon filled tub weighs over 330 pounds, not counting the tub and bather. If your home is on wheels, make sure the weight is evenly distributed over the trailer axles.
Types of Tiny Tubs for Tiny Houses
The beauty of today’s tiny tub designs is that they come in countless styles, shapes, and materials — each with a purpose and personality. Whether you prefer a traditional look or a minimalist aesthetic, there’s a tiny bathtub that can fit your needs perfectly.
Here are the most popular types of tiny tubs for tiny houses:
Soaking Tubs
Compact yet deep, soaking tubs are designed for full-body immersion while using less floor space. They’re a favorite among tiny house owners because they deliver the relaxation of a full bath in a fraction of the area.
Pros:
- Deep enough for comfortable soaking
- Minimal footprint
- Elegant and timeless look
Best for: Stationary tiny homes or loft-style layouts.
Japanese-Style Ofuro Tubs
Inspired by traditional Japanese bathing culture, ofuro tubs are tall, vertical tubs made for seated bathing. They use water efficiently and create a spa-like experience in a compact space.
Typical Size: 35–45 inches long × 25–30 inches wide × 30+ inches deep
Why They Work in Tiny Houses:
- Space-saving design
- Uses less water than standard tubs
- Can double as a shower base
“The ofuro tub transforms even the smallest bathroom into a serene sanctuary.”
Corner Tubs
When every inch counts, corner tubs make use of often-wasted bathroom corners. Their triangular design fits neatly into tight layouts and can make a small space feel open.
Ideal For: L-shaped or rectangular bathrooms in compact homes.
Tip: Use glass or light-colored materials to visually expand the space.
Freestanding Mini Tubs
If your goal is to make a statement, freestanding mini tubs deliver style and flexibility. They can be placed virtually anywhere — even under a window or near a wall with a view.
Pros:
- Easy installation (no wall framing needed)
- Visually appealing centerpiece
- Available in many modern or clawfoot designs
Cons: Usually heavier and may need floor reinforcement in mobile homes.
Portable and Inflatable Tubs
For off-grid or mobile living, portable bathtubs are an affordable and practical solution. Some fold or roll away when not in use, perfect for vanlifers or travelers.
Features:
- Lightweight and collapsible
- No permanent plumbing
- Great for temporary setups or outdoor bathing
Best Materials for Tiny Tubs
Material choice impacts not only the look of your tiny tub but also its weight, durability, and cost. Here’s a breakdown of the most common materials used in tiny tubs for tiny houses:
| Material | Weight | Durability | Price Range | Notes |
| Acrylic | Light | Moderate | $$ | Most popular; easy to clean and install |
| Fiberglass | Very light | Moderate | $ | Budget-friendly, but can scratch easily |
| Cast Iron | Heavy | Excellent | $$$ | Classic look; retains heat well, but very heavy |
| Wood (Ofuro) | Medium | High (with care) | $$$ | Natural, eco-friendly, requires maintenance |
| Composite/Stone Resin | Medium | Excellent | $$$ | Modern, durable, and stylish |
Tips for Choosing the Right Material
- For mobile tiny homes, choose lightweight acrylic or fiberglass.
- For stationary homes, stone resin or wood tubs create a high-end spa experience.
- Always check the total filled weight to ensure your floor structure can support it.
Tiny Tub Installation Considerations
Installing a bathtub in a tiny house takes more than just finding one that fits. You need to think through plumbing, drainage, heating, and even floor balance — especially if your home is on wheels.
1. Plumbing Constraints
- If your tiny house is connected to city utilities, standard plumbing works fine.
- Off-grid systems need careful water management — use on-demand water heaters and low-flow faucets.
- Drainage should slope slightly downward for proper flow.
2. Water Heating and Supply
Tiny tubs typically hold 30–50 gallons of water. A tankless water heater (2–4 GPM) is ideal for constant hot water without a bulky tank.
Pro Tip: Use insulated PEX pipes to reduce heat loss.
3. Structural Support and Weight Balance
A filled bathtub can weigh 300–400 pounds — more if you use a deep soaking model. For tiny homes on wheels, distribute weight evenly over the trailer axles. Reinforce the floor if needed with ¾-inch plywood and metal bracing.
4. DIY vs. Professional Installation
- DIY-friendly options: Portable tubs, acrylic soaking tubs, or corner tubs.
- Professional install needed: Cast iron or ofuro tubs, due to plumbing complexity and weight.
Estimated Installation Cost Range:
| Installation Type | Estimated Cost (USD) |
| DIY (portable/acrylic) | $200–$600 |
| Professional (custom plumbing) | $800–$2,000 |
| Luxury or ofuro installation | $1,500–$3,000 |
Tiny Tubs for Off-Grid Tiny Houses
For those living off-grid, a bathtub might seem like a luxury, but with smart planning, it’s completely doable. Off-grid setups prioritize water efficiency, heating, and drainage — and tiny tubs are ideal for that balance.
Water Supply and Storage
Most off-grid tiny houses rely on limited water sources, such as rainwater catchment or small storage tanks.
- Recommended Tub Size: Choose one that holds under 40 gallons.
- Water-Saving Tip: Reuse greywater from your tub for plants or toilet flushing (using a greywater filter).
- Low-Flow Fixtures: Install faucets that restrict water output without sacrificing comfort.
Heating the Water
Without a municipal supply, you’ll need an efficient heating system.
- Propane Tankless Heaters – Compact and great for instant hot water.
- Solar Water Heaters – Eco-friendly and cost-effective for sunny climates.
- Wood Stove Coils – A rustic, sustainable option for cabins or remote homes.
| Heating Method | Energy Source | Ideal For | Notes |
| Tankless Propane Heater | Gas | Mobile/off-grid | Heats instantly |
| Solar Thermal Heater | Sunlight | Stationary homes | Requires sunny conditions |
| Wood Coil Heater | Firewood | Cabins | Takes longer to heat but zero emissions |
Drainage and Greywater Systems
Because off-grid homes often use composting or incinerator toilets, tub drainage requires extra thought.
- Use a greywater collection system with a filter for reuse.
- Direct drainage at least 100 feet from natural water sources.
- Avoid soaps or shampoos with chemicals if you reuse water for gardening.
Off-grid bathing doesn’t mean giving up comfort — it’s about using resources wisely.
Creative Layout Ideas for Tiny House Bathrooms
Designing a tiny bathroom is like solving a puzzle — and fitting a tub makes it even more interesting. Luckily, clever design and multifunctional layouts can make your small bathroom both beautiful and functional.
Smart Space-Saving Ideas
- Under the Loft Stairs: Place a short soaking tub beneath your loft for efficient use of vertical space.
- Against a Window Wall: A small freestanding tub by a window creates an open, airy feel.
- Corner Tubs: Utilize corners to open up the middle of the room for easier movement.
- Wet Bath Layout: Combine your shower and tub in one waterproof area to save space.
- Raised Platform Design: Build your tub on a raised base to store plumbing or water tanks underneath.
Visual Tricks for Spacious Feel
- Use light colors, reflective surfaces, and minimal clutter.
- Glass partitions instead of curtains to open the visual flow.
- Install mirrors opposite natural light sources to make the space appear larger.
Multi-Functional Fixtures
Tiny homes thrive on flexibility. Consider:
- Foldable bath trays for extra counter space.
- Tub covers that convert into seating when not in use.
- Built-in storage ledges along the tub for soaps, candles, or décor.
Small doesn’t mean limited — it means intentional.
Tiny Tubs with Shower Combos
When space is tight, a tiny tub and shower combo offers the best of both worlds. You get the convenience of a quick shower and the indulgence of a relaxing soak — all within a few square feet.
Why Choose a Combo Setup
- Saves space by combining two functions in one.
- Provides flexibility for different routines or family members.
- Increases resale value, as buyers appreciate multi-use design.
Design Options
- Vertical Combo: Install a wall-mounted shower head above a soaking or ofuro tub.
- Sliding Door Enclosure: Prevents water from splashing into the rest of the bathroom.
- Curtain-Style Wet Zone: Ideal for super small bathrooms; affordable and easy to clean.
- Corner Tub + Shower Head: Great option for diagonal layouts or narrow rooms.
Waterproofing Tips
Proper waterproofing is key in these setups:
- Use cement board and waterproof membranes behind tiles.
- Apply 100% silicone sealant around edges and joints.
- Consider a floor drain in the entire bathroom area for peace of mind.
Example Layout:
| Feature | Description |
| Tub Type | 40″ acrylic soaking tub |
| Shower Head | Wall-mounted rain or handheld combo |
| Wall Finish | Waterproof tile or vinyl panel |
| Enclosure | Glass panel or curtain |
| Floor Drain | Centered under tub or offset |
With careful design, a tiny tub with a shower combo can turn a cramped bathroom into a modern, spa-like escape — efficient, functional, and stylish.
Luxury Touches: Making Tiny Tubs Feel Spa-Like
Just because your bathroom is small doesn’t mean it can’t feel luxurious. With a few thoughtful touches, your tiny tub can become the highlight of your tiny house — a peaceful retreat that feels like a spa, even in less than 50 square feet.
Design Details That Add a Spa Feel
- Natural Materials: Use wood, bamboo, or stone textures to create a calming atmosphere. A small cedar shelf or teak bath mat adds warmth and organic charm.
- Soft Lighting: Replace harsh overhead lights with dimmable LEDs or wall sconces. Candlelight can make even a metal tub feel inviting.
- Aromatherapy: Essential oils like lavender, eucalyptus, and citrus elevate bath time into a full sensory experience.
- Compact Bath Trays: A foldable tray for your book, tea, or tablet transforms a small soak into pure relaxation.
“Luxury in a tiny house isn’t about size — it’s about how intentionally you design your space.”
Small Upgrades That Make a Big Difference
| Upgrade | Purpose | Tiny-Friendly Tip |
| Heated towel rack | Comfort and faster drying | Wall-mounted, foldable models save space |
| Built-in storage niches | Keeps essentials handy | Use recessed shelves to save depth |
| Waterproof Bluetooth speaker | Relaxing music while soaking | Choose battery-powered, compact models |
| Fragrance diffusers | Improves air quality | Opt for USB-powered diffusers |
By layering textures, lighting, and scents, even the smallest tub setup can feel like a private wellness retreat.
Tiny Tub Maintenance and Cleaning Tips
Keeping your tiny tub clean is crucial not just for hygiene but also to protect your investment. Because tiny house bathrooms have limited ventilation, preventing mold and mildew should be a top priority.
Daily & Weekly Maintenance Tips
- Rinse after every use to remove soap residue.
- Use a soft cloth or sponge instead of abrasive brushes to protect finishes.
- Ventilate properly — open windows or use a small dehumidifier to keep moisture in check.
- Inspect seals and caulking monthly to prevent leaks.
Eco-Friendly Cleaning Options
Since many tiny homes use greywater systems, harsh chemicals can damage filters or harm plants if the water is reused. Instead, go green:
- Mix white vinegar and baking soda for a natural scrub.
- Use lemon juice for stain removal and freshness.
- Try biodegradable tub cleaners made for RVs or off-grid homes.
| Problem | Solution | Frequency |
| Soap scum | Vinegar + baking soda mix | Weekly |
| Mold or mildew | Hydrogen peroxide spray | As needed |
| Mineral buildup | Lemon juice soak | Monthly |
| Dull finish | Microfiber polish | Monthly |
Consistent care prevents damage — small tubs are easy to maintain if you stay on top of it.
Long-Term Care
- Reseal wooden ofuro tubs once a year.
- Repaint or refinish acrylic tubs if scratches appear.
- Always check plumbing joints for drips, especially after travel (for mobile homes).
Budgeting for Tiny Tubs in Tiny Houses
Adding a bathtub to your tiny home can range from surprisingly affordable to high-end luxury. The key is balancing your budget with functionality, aesthetics, and long-term maintenance.

Cost-Saving Tips

- DIY waterproofing. If you’re handy, you can tile or waterproof your own space using pre-formed shower panels.
- Use multi-purpose plumbing fixtures. A combined faucet and shower head saves money and space.
- Check RV and boat suppliers. They often carry durable, compact tubs perfect for tiny homes.
Smart spending isn’t about buying cheap — it’s about buying what fits your home and lifestyle perfectly.
Example Budget Breakdown
| Item | Cost |

| Fixtures & plumbing | $250 |
| Waterproofing materials | $150 |
