According to the 2025 U.S. Houzz Bathroom Trends Study, homeowners are increasingly investing in bathrooms that feel like personal wellness spaces. About 18% of renovated bathrooms now include soaking tubs or spa features, reflecting the growing demand for relaxation-focused upgrades.

In 2024, the median spend on bathroom renovations reached roughly $13,000, while complete remodels with major upgrades averaged around $22,000.

A Japanese soaking tub, or ofuro, provides this spa-like experience without the disruption of a complete remodel. Compact yet deep, these tubs fit smaller spaces while allowing for a full-body soak. They turn ordinary bathrooms into calming retreats, giving homeowners a daily chance to unwind.

What Makes a Japanese Soaking Tub Special?

A Japanese soaking tub differs from Western tubs in several key ways:

Deeper design: Most ofuros are 24 to 32 inches deep (compared to 14-16 inches for standard tubs

Upright seating: You sit instead of lying down, with water up to your shoulders

Compact footprint: Usually 40 to 60 inches long (shorter than standard 60-inch tubs)

Built-in bench: Allows comfortable sitting while soaking

Traditional ofuros are part of Japanese bathing culture. You shower first to cleanse, then soak in hot water for relaxation.

Planning Your Deep Tub Remodel: Measure Your Space

Before you start, measure your bathroom carefully:

Check the width, length, and height of your current tub area

Measure doorways (you need to fit the new tub through them)

Calculate the floor space around where the tub will sit

Verify your floor can support the extra water weight

Most compact soaking tubs need 40 to 48 inches of floor space. That's less than standard tubs, making them perfect for tight bathrooms.

Choose Your Tub Material

Japanese soaking tubs come in several materials:

Wood (Hinoki or Cedar)

•         Natural, aromatic, and authentic
•         Requires regular maintenance
•         Best heat retention
•         Price: $2,000 to $8,000+

Acrylic

•         Affordable and durable
•         Easy to clean and maintain
•         Available in many colors
•         Price: $900 to $3,000

Stone or Concrete

•         Premium look and feel
•         Excellent heat retention
•         Very heavy (check floor strength)
•         Price: $4,000 to $10,000+
•         For a DIY deep tub remodel, acrylic offers the best balance of cost and ease.

Step-by-Step Ofuro Installation

Step 1: Remove Your Old Tub

Start by removing your current bathtub:

Turn off the water supply

Disconnect the drain and faucet

Remove any tile or surround

Carefully remove the old tub

Check the subfloor for damage

Step 2: Prepare the Floor. Proper waterproofing is crucial:

•         Repair any floor damage
•         Install a waterproof membrane
•         Add a floor drain if needed
•         Slope floor toward drain (1/4 inch per foot)
•         Test waterproofing before proceeding

Step 3: Position Your New Tub

Place your compact soaking tub carefully:

Slide the tub into position

Level it using shims if needed

Leave access to the drain

Check clearance around the tub

Most ofuros don't need to be secured to walls.

Step 4: Connect Plumbing

Connect your water supply and drain:

Attach faucet (wall-mounted or freestanding)

Connect the drain line

Test for leaks

Add overflow if your model has one

Some tubs need electrical connections for jets or heaters. Hire a licensed electrician for this work.

Step 5: Add Finishing Touches

Complete your zen bathtub design:

Install waterproof wall panels or tile

Add non-slip flooring around the tub

Install grab bars for safety

Apply caulk if needed

Making Your Bathroom Feel Like a Spa

A Japanese soaking tub is more than a tub; it's an experience. Add these elements:

Natural materials (wood, stone, bamboo)

Soft, warm lighting

Indoor plants

Minimal clutter

Keep cleaning supplies and toiletries hidden. The space should feel calm and open.

Maintenance Tips for Your New Ofuro

Keep your compact soaking tub in great shape:

Daily Care

Rinse after each use

Wipe down to prevent water spots

Dry wooden tubs completely

Weekly Cleaning

Use mild soap (never harsh chemicals)

Clean the drain and overflow

Wipe all surfaces

Seasonal Tasks

Seal wooden tubs every 6-12 months

Check caulking and waterproofing

Inspect drain connections

Common Deep Tub Remodel Mistakes to Avoid

Don't make these errors:

Skipping floor reinforcement: Deep tubs hold lots of water. Make sure your floor can handle it.

Poor ventilation: Moisture builds up fast. Install a good exhaust fan.

Wrong size selection: Measure twice, order once. Include door widths.

Cheap materials: Quality tubs last for decades. Cheap ones crack or leak.

DIY electrical work: Always hire licensed pros for electrical connections.

Cost Breakdown for Your Ofuro Installation

Budget for these expenses:

Tub: $900 to $8,000 (depending on material and size)

Plumbing modifications: $500 to $2,000

Waterproofing: $300 to $1,000

Flooring: $400 to $1,500

Labor (if hiring pros): $1,500 to $4,000

Accessories: $500 to $2,000

Total range: $4,000 to $15,000 for a complete deep tub remodel. DIY installation saves on labor but requires skill.
