60 Vs 66 Inch Bathtub [With Pros Cons]

For many homeowners, choosing between a 60 inch and 66 inch bathtub can be a difficult decision. Even just those extra 6 inches can make a big difference in terms of bathing comfort, space in your bathroom, and installation requirements.

In this comprehensive guide, we’ll go over the key distinctions between 60 inch and 66 inch tubs, factors to keep in mind when choosing between the two sizes, and the pros and cons of each option. We’ll also provide an overview of popular bathtub styles and models available in both dimensions.

Whether you’re doing a bathroom remodel or installing a new tub in new construction, understanding the difference between 60 inch and 66 inch tubs will ensure you select the size that best fits your needs and space.

Here is an in-depth comparison table contrasting 60 inch and 66 inch bathtubs:

Key Differences Between 60 Inch and 66 Inch Bathtubs

While only 6 inches separate these two common tub sizes, those 6 inches can significantly impact your bathing experience. Here are some of the key variances between 60 inch and 66 inch bathtubs:

Dimensions and Capacity

The exterior dimensions of a 60 inch tub are typically 60″ long x 32″ wide x 19″ high. The interior bathing well is around 42″ long and 22″ wide.

A 66 inch tub is usually 66″ long x 32″ wide x 19″ high. The interior bathing well averages 46″ long and 22″ wide.

Those extra 6 inches of length in a 66 inch tub provide additional space to stretch out and relax. The greater length also equates to more bath water capacity. A 66 inch tub holds around 45-50 gallons, while a 60 inch holds 35-40 gallons.

Cost

In general, expect to pay $100-$300 more for a 66 inch tub compared to a 60 inch of the same model and material. The additional materials and manufacturing complexity add to the cost.

Luxury and high-end models in materials like stone, acrylic, or enameled cast iron have an even greater price jump from 60 to 66 inches. Simple tubs in vinyl, fiberglass, or enameled steel have a smaller cost increase.

Installation Considerations

The small difference in length has an outsized impact on installation. Those extra 6 inches require additional floor space that some bathrooms may not have.

60 inch tubs can fit in alcoves or surrounds as small as 5 feet wide. 66 inch tubs need a minimum alcove of 5 feet 6 inches, but 6 feet is better.

The plumbing also must accommodate the extra length for a 66 inch tub. Supply lines, drains, and overflows may need to be shifted or extended. This could add complexity and labor costs.

So in summary – 66 inch tubs provide more bathing capacity but cost more and have stricter install requirements. 60 inch tubs are simpler to fit in small spaces but feel more cramped. Let’s go over other factors to help you decide which size works best.

Factors to Consider When Choosing Between 60 Inch and 66 Inch Tubs

Beyond just dimensions, there are a few key considerations when determining whether a 60 inch or 66 inch bathtub is the right size for your space and needs:

Bathroom Size and Layout

The most limiting factor is whether your bathroom can physically accommodate a 66 inch tub. As mentioned above, you need a minimum 5 foot 6 inch width for the tub surround. Measure carefully to ensure you have the floor area before committing to a larger 66 inch model.

Also examine the placement of windows, doors, and fixtures. Will you have to shift or move plumbing to make a 66 inch tub fit? This may be inconvenient or costly.

User Height and Space Needs

Think about the primary user’s height and how much space they need to fully submerge and extend their legs. Taller users over 5 foot 8 will likely appreciate the extra room of a 66 inch tub. Shorter bathers may fit fine in 60 inches.

Consider body proportions too. Do you prefer to sit upright with bent knees? Then a compact tub could work. Do you like to recline and stretch out? Opt for a roomy 66 inch model.

If two people use the tub, the longer size provides more tandem bathing space as well. Just note most tubs are only wide enough for solo bathing.

Budget

As noted earlier, expect to spend $100-$300 more for a 66 inch tub of the same style and material as a 60 inch. High-end models have an even greater price jump.

Set a firm tub budget beforehand so you can immediately narrow options to affordable 60 or 66 inch sizes. Spending more for those extra 6 inches may or may not be worth it depending on your finances.

Aesthetics and Style

The dimensions can impact the overall look and design too. A 60 inch tub can feel cramped in a large bathroom. But a 66 inch may dwarf a tiny space.

Freestanding tubs look best with ample open floor around them. A 60 inch often appears more proportional. Alcove fit tubs must match the surround size, limiting flexibility.

If you have a favored style – say a classic clawfoot or sleek corner tub – check manufacturers offer both 60 and 66 inch options. Some limit models to just one size.

So taking all these factors together will guide your dimensions decision for the ideal user experience. Now let’s compare some pros and cons.

Pros and Cons of 60 Inch Bathtubs

To recap, here are the positives and negatives of selecting a 60 inch bathtub:

Pros of 60 Inch Tubs

• Fit easily in alcoves or surrounds as small as 5 feet wide
• Require less floor space and plumbing adjustments for installation
• Typically $100-$300 cheaper than same model in 66 inches
• Provide ample bathing space for average to short users
• Allow more styling flexibility in small bathrooms

Cons of 60 Inch Tubs

• Limited stretch out room for tall users over 5′ 8″
• Feel cramped for tandem bathing
• Offer less immersion depth and bath water capacity
• Can appear small scaled in larger bathrooms
• Fewer models available than 66 inch size

So for smaller bathrooms, tighter budgets, or shorter users – a 60 inch tub can be perfectly adequate. But tall people or those wanting to really stretch out may feel confined.

Now let’s examine the pros and cons of upgrading to a 66 inch bathtub.

Pros and Cons of 66 Inch Bathtubs

Here are the advantages and disadvantages of selecting a 66 inch tub:

Pros of 66 Inch Tubs

• Allow full leg extension for tall users over 5′ 8″
• Provide ample tandem bathing room
• Increased water depth and capacity
• Feel spacious even in large bathrooms
• Wider selection of models available

Cons of 66 Inch Tubs

• Require minimum 5′ 6″ alcove or surround width
• Additional complexity for install and plumbing
• Cost $100-$300+ more than same model in 60 inches
• Can feel overly long and awkward in small baths
• Limited styling options for truly cramped spaces

The main tradeoff is comfort and capacity versus installation ease and cost. If budget is no concern and you have ample floor space, a 66 inch tub can be a luxurious choice. But for smaller bathrooms or budgets, stick with an easier to fit 60 inch size.

Now that you understand the key distinctions, let’s look at some popular styles of both size tubs.

Popular Styles and Models of 60 Inch and 66 Inch Tubs

Bathtubs come in a range of configurations from alcove to freestanding models. Here are some of the most common types available in both 60 inch and 66 inch lengths:

Alcove Bathtubs

This style fits into a surround alcove enclosed on three sides. Most alcove tubs come in both 60 and 66 inch sizes to flexibly fit different surround dimensions. Models include:

• American Standard Cadet
• Kohler Archer
• Sterling Ensemble

Look for a depth of at least 14 inches for comfortable soaking. Deeper models like the Kohler Expanse are especially luxurious.

Drop-in Bathtubs

Drop-in or platform tubs sit atop a raised tile or wood platform. Some key models include:

• Kohler Tea-for-Two
• American Standard Princeton
• KALDEWEI Cayono

These can be especially sleek and modern in appearance. Just remember to factor in platform construction costs.

Freestanding Bathtubs

Freestanding tubs stand alone on the floor without an alcove or surround. Popular models available in both sizes include:

• Woodbridge B-0034 / B-0036
• Empava EMPV-FT146 / EMPV-FT166
• Vanity Art VA 6752 / VA 6756

A free standing style can make a dramatic focal point. Be sure to have adequate floor space around the tub.

So in summary, both 60 and 66 inch tubs come in a variety of configurations to meet your needs. Carefully consider the pros and cons and measure your bathroom carefully before deciding. An extra 6 inches can make a surprisingly big difference in your daily bathing comfort and satisfaction.

Pros and Cons of Different Bathtub Materials

Bathtubs come in a variety of materials, each with their own advantages and disadvantages. Key factors to compare are durability, appearance, cost, and cleaning requirements. Here’s an overview of common tub material pros and cons:

Acrylic

Acrylic is a lightweight, flexible plastic that’s reinforced with fiberglass.

Pros:

• Warm, smooth feel
• Range of color options
• Resists chipping and scratches
• Easy to clean
• Moldable for ergonomic shapes
• Non-porous surface limits bacteria
• Budget friendly

Cons:

• Not as durable as cast iron or natural stone
• Can show scratches over time
• Requires gentle abrasives for stain removal
• Matte finish can appear dull

Acrylic is a great choice for the look of natural stone at a lower cost. Just avoid harsh cleaners that can damage the surface.

Cast Iron

Cast iron tubs are extremely heavy but durable. The material is coated in a porcelain enamel.

Pros:

• Excellent heat retention
• Very durable and scratch resistant
• Enamel coat resists staining
• Timeless, classic appearance
• Can be refinished over decades of use
• Good value for the price

Cons:

• Very heavy, difficult to install and move
• Vulnerable to chipping if hit hard
• Noisy when draining or filling
• Requires special bleach-free cleaners
• Limited color and style options

Cast iron excels at durability and heat retention. The weight and old-fashioned styling may not suit all bathrooms.

Natural Stone

Stone tubs are carved from solid marble, granite, onyx or other natural stones.

Pros:

• Unique veining patterns
• Luxurious feel
• Excellent heat retention
• Stain resistant surface
• Ages beautifully over decades
• Environmentally friendly natural material

Cons:

• Expensive, especially for large tubs
• Extremely heavy, may require reinforcement
• Can chip, crack, or stain if not sealed properly
• Requires yearly re-sealing
• Limited style selection

For a premium spa-like experience, nothing beats relaxing in warm natural stone. But the costs and weight make stone best for custom luxury homes.

Ceramic/Porcelain

Fired clay or porcelain creates a glossy, ceramic tub that’s lighter than cast iron but still rigid.

Pros:

• Hard, non-porous surface resists staining
• Range of color and finish options
• Rigid for comfortable bathing
• Lower cost than stone or acrylic
• Easy to clean

Cons:

• Not as durable as other materials
• Chips, scratches and cracks more easily
• Noisy when draining or filling
• Limited style selection compared to acrylic

Ceramic delivers an attractive, affordable tub option. Just take care to avoid surface damage from impacts or dropped bottles.

Overall acrylic and cast iron provide the best blend of affordability, durability, and style options. Weigh your budget, bathroom aesthetic, and tub longevity needs when selecting materials.

Key Dimensions for Comfortable Bathing

Beyond just overall tub length, certain interior dimensions impact bathing comfort. Consider these specs when shopping 60 or 66 inch tubs:

Tub Depth

A minimum depth of 14 inches provides a nice immersion for relaxation. Look for at least a 12 inch depth for soaking lower body and back. For legs-only baths, a 10 inch high tub can suffice.

Deeper tubs require more water to fill, but allow reclining to wet shoulders and neck. Check your hot water heater capacity if opting for a extra deep model.

Tub Width

Most standard tubs are 30-32 inches wide externally. This leaves a 22-24 inch interior seat width – wide enough for solo bathing, but tight for two people.

For tandem bathing, some extra wide models measure 60-72 inches long but also 42-48 inches wide. These tubs feel far more spacious.

Just remember to measure your bathroom to ensure you have the floor area for an oversized wide tub.

Slope and Lumbar Support

A gentle sloped back or contoured lumbar dip provides more comfortable reclining than a flat backrest.

Look for an ergonomic inner molding with at least a 15-20 degree back slope. This supports the spine and neck while soaking.

Arm Rests

Integrated tub armrests allow relaxing with arms supported out of the water. This reduces shoulder strain.

Rests should be at least 4 inches wide and gently sloped inward. Wider arm ledges offer even better ease.

With the right interior ergonomic design, even a standard 60 inch tub can enable full-body relaxation. Prioritize depth, sloped back support, and arm rests over simply length.

Special Features to Consider

Beyond size and design, today’s bathtubs offer indulgent special features. Here are some popular add-ons to enhance your bathing experience:

Jetted Massage

Jetted tubs use focused streams of air or water to provide massaging bubbles and currents. This transforms a bath into a spa-like experience.

Most jets offer adjustable pressure and temperature controls. Look for at least 8 jets for thorough body coverage.

Installation is more complex with jetted tubs – consider a professional if DIYing. Jets also limit tub material options.

Air Bubble Massage

For a simpler hydro massage, many tubs include air bubble jets along the floor and walls. These surround you in stimulating bubbles without water jets.

Most systems allow adjusting bubble intensity. Just 10-20 minutes can relax away aches and pains.

Chromatherapy Lighting

Multi-color LED mood lights are an affordable way to add ambience and relaxation to bath time. Common options include:

• Wall-mounted tub lights in waterproof housings
• Fiber optic point lights around the tub exterior
• Acrylic tub base or sidewall illumination

Look for full RGB color blending and multiple pre-set modes for ultimate enjoyment.

Microbubble Technology

Some acrylic and stone tubs feature microbubble generators that infuse billions of tiny air bubbles into the bathwater.

This maintains heat while creating a silky, champagne-like bathing experience. Microbubbles also moisturize skin beautifully.

Inline Heaters

These heaters mount to the water supply line to actively maintain your ideal bath temperature. No more cooling water ruining a long relaxing soak!

Models from Kohler and others automatically throttle heater output based on the incoming water temp. This avoids overheating accidents.

While sometimes pricey, special features like massaging jets or microbubbles can make a home bathtub feel like a spa. Choose one or two that best suit your budget and bathing preferences.

Tub Faucet and Filler Considerations

Don’t overlook the importance of tub fillers and faucets for completing your bath design. Here are key factors to keep in mind:

Fill Speed

A standard tub takes 4-7 minutes to fill with around 20 gallons per minute from the faucet. For a longer or deeper tub, this can mean 15+ minutes waiting for enough water depth.

Look for tub fillers or diverters rated at 4-5 GPM or higher. This cuts fill times significantly.

Rough-in valves with multiple 1/2″ feeds can allow dual 8-10 GPM fills – reducing even a 66 inch tub time to just a few minutes.

Faucet Design

The tub spout and handles finish off your bath decor. Matching widespread faucets, Roman tub sets, or wall-mount styles all work.

Focus on easy-clean designs and quality metal finishes to coordinate with other bathroom hardware and fixtures.

Overflow vs. Drain-only

Many modern tubs utilize a click-open drain with no visible overflow. This enables sleek minimal styling.

But missing an overflow means risking water spilling onto the floor from an overfilled bath. Include an overflow if this may be a concern.

Freestanding Tub Fillers

For freestanding tubs, look for tub-mounted or wall-mounted fillers that arch elegantly over the side. Floor-mount fixtures can also work well.

Avoid awkward hoses draped over the side if opting for a freestanding style. This ruins the sleek aesthetic.

Put just as much thought into your ideal faucet and filler as you do choosing the perfect tub size and style. Don’t let the wrong fixtures ruin your spa-like retreat!

Key Installation Considerations

Installation is where precise tub measurement and bathroom planning really pay off. Avoid headaches by planning ahead for:

Tub Alcove Size

Double check the alcove or surround area matches your selected tub length. Allow an extra 1-2 inches gap on any side constrained by walls.

Also ensure plumbing, windows, or doors won’t interfere – you generally want 16-24 inches clearance from these fixtures.

Door Access

Measure doors along the installation path to ensure the tub will fit through. Freestanding tubs often require temporary door removal.

For alcove tubs, look for designs with slip-in or tilting assemblies that enable tight space maneuvering.

Weight Support

Heavier materials like cast iron or stone may require floor reinforcement. Consult a structural engineer before installation, especially for elevated bathrooms.

Thick mortar beds topped with concrete backerboard help level and support the tub weight in wood frame construction.

Plumbing Modifications

Check that drain, supply, and if needed overflow locations fit your rough-in plumbing. Adjust piping as needed before securing the tub.

Clawfoot tubs usually require some exposed plumbing, while alcove tubs can utilize wall-concealed supplies.

Framing and Finish Work

For alcove installations, frame out backing walls with moisture resistant drywall or cement board. Waterproof drywall is a good option.

Finish the surround with easy-clean tile, solid surfacing, or waterproof plank panels. Enclose all edges to prevent water intrusion.

Hiring a professional for installation is advisable for tougher renovation projects. But with planning and prep, DIYing your dream tub is certainly feasible.

Bathtub and Bathroom Safety Tips

Stay safe and prevent injuries with these bathroom and bathtub safety tips:

Grab Bars

Install securely mounted grab bars inside the tub and around the bathroom. These assist entering and exiting for seniors or those with mobility issues.

Look for bars with textured gripping surfaces. Position horizontally and vertically to enable getting seated and standing upright.

Non-Slip Surfaces

Use non-slip tub mats, appliques or textured stickers inside the bath basin. These create traction to avoid slipping when wet.

Also utilize non-skid floor tiles or appliques on bathroom floors prone to getting wet.

Thermostatic Valve

A thermostatic mixing valve on the tub ensures a safe bathing temperature. Straight hot water from the heater could scald.

The valve automatically mixes with cold water, and prevents exceeding a preset comfortable bathing temp.

Bath Seat or Bench

Install a sturdy bath seat for those who need seated support getting in and out of the tub.

Freestanding benches let you adjust legroom. Fully integrated seats save space in alcoves.

Nightlights

Install nightlights at tub and hallway edges to illuminate the path after dark. This prevents tripping or falls.

For those with vision or mobility impairment, rope lights along the tub rim work well.

Cushioned Bath Mats

Placing cushioned bath mats on hard tub floors boosts comfort and safety when bathing.

The soft padding protects against bumps and bruises if slipping or falling inside the tub.

Adjust your bathroom lighting, accessories, and hardware to enable safe, independent bathing for all ages and mobility levels.

Conclusion

Whether opting for a space-saving 60 inch tub or indulgent 66 inch model, carefully measure your bathroom and assess your needs. This ensures picking the size that best suits your space, bathing preferences, and budget.

Factor in special features like massaging jets or perfect faucets to create a truly spa-worthy retreat right in your home bathroom. Follow installation and safety best practices to enjoy a beautiful, soothing bathtub for years to come.
