1. WOODBRIDGE B0013 67″ Acrylic Freestanding Soaking Bathtub

The WOODBRIDGE B0013 is the best overall soaking bathtub for most homeowners — a spacious 67″ contemporary oval built from 100% Lucite acrylic reinforced with ASHLAND resin and fiberglass, with a double-walled construction that keeps water noticeably warmer for longer than single-wall competitors.

At 60 gallons effective capacity and with gently sloping lines that follow the natural curve of the spine, it delivers a full-body immersion experience that feels genuinely luxurious at a price point well below what you’d expect from a tub this refined.

Features

• 67″ x 31½” x 28⅜” contemporary oval freestanding form
• 100% Lucite acrylic reinforced with ASHLAND resin and fiberglass
• Double-walled construction for superior heat retention
• 60-gallon effective capacity; approximately 16″ soaking depth
• ENDURACLEAN surface — stain-resistant, scratch-resistant, non-discolouring
• Stainless steel bracket base with up to 1,000-lb load capacity
• Compliant with CSA B45.5-17/IAPMO Z124-2017 standards

Pros

• Double-walled insulation is a genuine differentiator for long soaks
• Lucite acrylic is warmer to the touch than standard acrylic — much more comfortable
• ENDURACLEAN surface stays looking new with minimal maintenance
• Generous 67″ length accommodates taller bathers comfortably
• Clean contemporary lines suit any modern or transitional bathroom style

Cons

• Requires a floor-mount freestanding faucet — not included
• 67″ length requires careful measurement before ordering
• One-year warranty is shorter than some competitors in this category

If you want one soaking bathtub that gets everything right — depth, heat retention, build quality, and looks — the WOODBRIDGE B0013 is the one to start and finish your search with.

2. WOODBRIDGE B-0006 54″ Acrylic Freestanding Soaking Bathtub

Not every bathroom has room for a 67″ statement tub — and the WOODBRIDGE B-0006 is the answer for smaller master bathrooms that still deserve a proper freestanding soaking experience.

It shares the same Lucite acrylic and ASHLAND resin construction as the larger B0013, with the same double-walled insulation and ENDURACLEAN surface, simply packaged into a more compact 54″ footprint that fits where the bigger tub simply won’t.

Features

• 54″ x 29½” x 23⅝” compact freestanding oval
• Same 100% Lucite acrylic + ASHLAND resin + fiberglass construction as B0013
• Double-walled design for heat insulation and structural rigidity
• ENDURACLEAN stain-resistant and scratch-resistant surface
• Stainless steel bracket base rated to 1,000 lbs
• Gently sloping interior for ergonomic back support
• CSA B45.5-17/IAPMO Z124-2017 compliant

Pros

• Brings WOODBRIDGE’s premium build into a bathroom too small for 59″+ tubs
• Double-walled insulation and Lucite acrylic at this compact size is rare
• Lighter and easier to manoeuvre during installation than larger freestanding models
• Identical surface treatment to the larger lineup — same clean, high-gloss finish

Cons

• 54″ interior is snug for taller bathers — check the seating dimension before ordering
• Freestanding faucet not included — needs to be sourced separately
• Smaller capacity means less total water volume for deep soaking

If limited floor space has been holding you back from a freestanding soaking bathtub, the WOODBRIDGE B-0006 proves that compact doesn’t have to mean compromised.

3. ANZZI Ami Series FT-AZ401 67″ Flat Bottom Soaking Bathtub

The ANZZI Ami is the pick for bathers who prioritize maximum water volume above all else — its 91-gallon capacity is the highest on this list, giving you the deepest full-body immersion experience of any tub here.

The flat-bottom design with a 45.67″ sitting area and sloping backrest is genuinely comfortable for extended soaks, and the marine-grade acrylic with Rhino Alloy fiberglass reinforcement gives it a one-piece seamless construction that’s both elegant and durable.

Features

• 66.93″ x 29.53″ x 22.44″ flat-bottom freestanding form
• 91-gallon capacity — largest water volume on this list
• 13.78″ soaking depth with 45.67″ x 18.9″ sitting area
• Marine-grade acrylic with Rhino Alloy fiberglass reinforcement
• Seamless one-piece construction — no seams to clean or seal
• Slip-resistant floor texture and adjustable leveling feet
• Center drain; overflow and drain included; lifetime warranty from ANZZI

Pros

• 91-gallon capacity delivers the most immersive soaking experience in this roundup
• Flat-bottom design gives maximum usable floor space inside the tub
• One-piece seamless construction is more hygienic and easier to clean
• Lifetime warranty is the strongest coverage on this list
• Slip-resistant floor is a genuine safety and comfort upgrade

Cons

• 91-gallon capacity means a much longer fill time and higher hot water demand
• Flat-bottom design, while spacious, offers less ergonomic recline than oval tubs
• Freestanding faucet not included

For bathers who want to truly disappear into a full-body soak rather than just sitting in warm water, the ANZZI Ami’s 91-gallon capacity sets it apart from everything else at this price point.

4. FerdY Bali 55″ Acrylic Freestanding Soaking Bathtub

The FerdY Bali is the most visually distinctive bathtub for soaking on this list — its gracefully sculpted curves and hand-finished details give it a character that standard contemporary oval tubs simply don’t have, while its insulated shell and 15″ soaking depth make it genuinely practical for everyday use.

At 55″ it’s compact enough for smaller bathrooms, yet its elegant silhouette makes it look far more expensive than it is — a combination that’s genuinely hard to find in this category.

Features

• 55″ x 28″ freestanding sculpted oval with 15″ soaking depth
• 100% glossy white acrylic reinforced with fiberglass (FerdY Luxcite formulation)
• Insulated shell construction for extended heat retention
• Integrated slotted overflow for deep soaking without a separate overflow fitting
• Toe-tap chrome drain with 22GA brass tailpiece and flexible PVC drainpipe
• Up to 1,750-lb load capacity — the highest structural rating on this list
• cUPC certified; 6-year limited warranty

Pros

• 15″ soaking depth at 55″ length is impressive — punches well above its size class
• Sculpted curves and hand-finished details give it a character no flat-line tub matches
• 1,750-lb load capacity is exceptional — suitable for two bathers
• 6-year warranty is significantly longer than WOODBRIDGE’s one-year coverage
• Insulated shell keeps water warm for longer extended soaks

Cons

• 55″ is compact — taller bathers over 5’10” may feel the length limit
• Sculpted organic shape means it suits certain bathroom aesthetics more than others
• Freestanding faucet sold separately

The FerdY Bali is the soaking bathtub for buyers who want something with genuine personality — a tub that looks like a design choice rather than a default, without paying luxury prices for it.

5. WOODBRIDGE BTA1518 59″ Acrylic Freestanding Soaking Bathtub

The WOODBRIDGE BTA1518 is the mid-size sweet spot — longer than the 54″ B-0006 but shorter than the 67″ B0013, giving you more soaking room than a compact tub without the floor space demands of a full-size model.

It carries the same Lucite acrylic, ASHLAND resin, fiberglass reinforcement, and double-walled insulation as the rest of the WOODBRIDGE lineup, making it the most practical all-rounder for mid-size master bathrooms where every inch of floor space counts.

Features

• 59″ x 29½” contemporary oval freestanding form
• 100% Lucite acrylic with ASHLAND resin and fiberglass reinforcement
• Double-walled insulated construction for heat retention
• ENDURACLEAN stain-resistant and scratch-resistant surface
• Stainless steel base bracket rated to 1,000 lbs
• Gently sloping ergonomic interior lines for back and lumbar support
• CSA B45.5-17/IAPMO Z124-2017 compliant

Pros

• Ideal mid-size option — comfortable for most adults without dominating the room
• Same premium Lucite acrylic construction as WOODBRIDGE’s larger models
• Double-walled insulation keeps water warm throughout a full soaking session
• Proven ENDURACLEAN surface stays bright and easy to clean long-term
• Familiar oval silhouette pairs well with virtually any bathroom style

Cons

• One-year warranty — shorter than FerdY or ANZZI coverage
• Freestanding faucet not included
• Less visual character than the FerdY Bali — clean and contemporary but not distinctive

If the 67″ model is too large and the 54″ model is too small, the WOODBRIDGE BTA1518 is the Goldilocks pick — a reliable, beautifully made soaking bathtub that fits the way most mid-size bathrooms actually work.

How to Choose the Best Soaking Bathtub for Your Bathroom

1. Measure your floor space before anything else.

Freestanding soaking bathtubs need clearance on all sides — typically at least 6–12 inches — so the tub footprint you need is larger than the tub’s exterior dimensions alone.

Factor in where the drain and faucet will sit relative to your existing plumbing before committing to a size.

2. Prioritize soaking depth over tub length.

A longer tub doesn’t always mean a deeper soak — depth to overflow is the spec that determines how much of your body is actually submerged.

Look for a minimum soaking depth of 14–15 inches; anything under 13 inches will leave your shoulders and chest above the waterline.

3. Choose your material based on how long you like to soak.

Acrylic tubs with double-walled insulation — like the WOODBRIDGE lineup — retain heat significantly better than single-wall designs, making them far more practical for extended soaking sessions.

Cast iron retains heat even better but adds hundreds of pounds of weight that may require floor reinforcement.

4. Budget for a freestanding faucet separately.

Almost no freestanding soaking bathtub in this category includes a faucet — it’s always a separate purchase.

A floor-mount freestanding faucet needs to reach comfortably to the tub’s deck without leaning, so measure the distance from your planned drain rough-in to where the faucet will stand before ordering.

Tips for Getting the Most from Your Soaking Bathtub

1. Pre-warm the tub shell before filling.

Run a small amount of hot water over the interior surface for a minute or two before filling — a cold acrylic shell will pull heat out of your water faster than you’d expect, especially in cooler months.

2. Use a bath caddy to make longer soaks practical.

A good caddy across the rim holds your book, phone, drink, or candle at arm’s reach, which means you’ll actually stay in the tub long enough to feel the benefit of the soak rather than climbing out after ten minutes out of boredom.

3. Clean the surface after every few soaks, not just occasionally.

Acrylic is easy to clean but benefits from regular light maintenance — a non-abrasive cleaner after every few uses prevents soap scum and body oil buildup from dulling the high-gloss finish over time.

Our guide to the best way to clean a walk-in tub covers acrylic-safe cleaning methods that work equally well on standard freestanding soakers.

4. Install a thermostatic mixer or tankless water heater if your hot water runs out quickly.

A 60–91 gallon soaking tub draws a lot of hot water at once — more than many standard water heaters can supply in one go.

If you find the water cooling before the tub is full, a larger water heater or a thermostatic mixing valve is a worthwhile investment alongside the tub itself.

Frequently Asked Questions

What is the ideal soaking depth for a bathtub?

Most soaking tub experts recommend a minimum of 14–15 inches of water depth to overflow for a genuine full-body immersion experience.

Standard alcove bathtubs typically offer only 10–12 inches, which is why purpose-built soaking tubs feel so dramatically different.

Do freestanding soaking bathtubs require special plumbing?

Yes — freestanding tubs need a floor-mount drain rough-in positioned correctly under the tub, and a separate freestanding or wall-mount faucet.

If you’re replacing an alcove tub, your plumber will need to relocate the drain and supply lines, which adds to the installation cost.

How long does a soaking bathtub keep water warm?

It depends heavily on the shell construction.

A double-walled acrylic tub like the WOODBRIDGE models will hold heat noticeably longer than a single-wall design — typically maintaining comfortable temperature for 30–45 minutes rather than 15–20.

Cast iron and stone resin tubs retain heat even longer, often 60+ minutes, though they cost significantly more and weigh far more.

Is a freestanding soaking tub worth it?

For daily bathers who use the tub regularly, absolutely — the combination of deeper immersion, better heat retention, and the genuine enjoyment of a well-designed space makes the investment worthwhile.

For occasional bathers, the cost of replumbing and the faucet purchase may not be justified — a deep alcove soaker could be a more practical upgrade.

Conclusion

The best bathtub for soaking is the one that fits your bathroom, suits your body, and makes you want to use it every single day — not just when you have an hour to spare.

For most homeowners, the WOODBRIDGE B0013 67″ delivers the ideal combination of soaking depth, heat retention, and build quality.

For smaller spaces, the WOODBRIDGE B-0006 54″ or FerdY Bali 55″ give you everything that matters without the floor space demands.

And for the ultimate volume of immersive water, the ANZZI Ami’s 91-gallon capacity is genuinely in a class of its own.
