Installing a bathtub in a small bathroom can be like solving a puzzle. You’ll need to take careful measurements, pick the right size bath, and then make sure it all fits without making the bathroom feel cramped.
From choosing the right style to getting the arrangement just right, we’ll give you all the knowledge you need to successfully install a bathtub in a tight bathroom.
Let’s take an in-depth look at how you can make your small bathroom both stylish and functional with the perfect bathtub.
Evaluating Bathroom Space

Embarking on a successful bathroom remodel necessitates a solid plan and a thorough evaluation. Before you commence remodeling, it’s crucial to assess your bathroom space.
This is where a meticulously crafted floor plan comes into play. It’s not just a sketch; it’s your guide, steering you around hurdles and ensuring everything fits snugly.
When devising the floor plan, consider key details such as the distance between the basin or front of your toilet and any other obstruction, which should be at least 510mm.
The recommended space is at least 760mm. Follow the steps below to effortlessly evaluate your bathroom space and feel in command of your project.
No need to worry about how to replace a bathtub anymore. Simply measure the old bathtub and create an accurate floorplan of the entire bathroom, noting plumbing details like faucets and drains.
Specify the length and width of the bathtub space and mark the drain location on paper to facilitate easier planning and rearrangement before physically moving fixtures.
Replacing a bathtub in older homes entails leveling the subfloor after removing the old tub. This is a pivotal step as it guarantees the floor beneath the new tub is even and can bear the fixture’s weight.
Due to natural settling over time, it’s crucial to adhere to the manufacturer’s instructions to add mortar or the recommended material. This will certify the subfloor is appropriately leveled and primed for the new tub.
Removing the old tub from the bathroom can be done easily by placing it on the side and taking it out vertically. However, this step may require strong friends to assist in the process.
Before replacing the old tub, consider removing the sink and toilet to create more space for moving. This step is not just a suggestion; it’s a valuable strategy.
It enhances efficiency during the replacement process and is appreciated by the crew involved in the bathtub replacement in a confined bathroom space. You’ll see the difference it makes.
Choosing the Right Size Bathtub
The standard bathtub dimensions are 60 inches long, 30 inches wide, and 14-16 inches high. Choosing from the small bathtub sizes depends on your bathroom space and personal preference.

You should keep in mind that claw-footed tubs and freestanding bathtubs have been common in the past and are now making a comeback. The main reasons why they are getting popular are:
● Measurement of space: ensure that the length, width, and height of your bathroom are accurately measured.
For example, if your bathroom is 2.5 meters (approx. 8 feet) long and 1.5 meters (approx. 5 feet) wide, it would be more appropriate to choose a bathtub that is no longer than 2 meters (6.5 feet) in length and no wider than 0.8 meters (2.6 feet) to allow for adequate space for movement.
● Usage requirements: Consider how often the bathtub will be used and the number of users. For example, a family of four may need a bathtub with a length of at least 1.7 meters (approx. 5.5 ft.) and a width of 0.75 meters (approx. 2.5 ft.) for shared use.
● User size: Choose a bathtub size that allows full body extension. For adults over 1.75 m (5.7 ft) tall, a bathtub with a length of at least 1.8 m (about 6 ft) is recommended.
● Water volume and water heater capacity: a standard-sized bathtub (about 170cm x 75cm x 40cm) requires about 200 to 250 liters (about 53 to 66 gallons) of water to fill.
Make sure your water heater is supplied with at least 70 percent of this capacity to avoid running out of hot water.
● Tub style: choose a style based on the layout and style of your bathroom. Free-standing tubs may require more space, while built-in and corner tubs make better use of limited space.
● Budget: Prices vary by size, material, and brand. Set a clear budget range, such as $500 to $2,000, and then look for options within that range.
● Installation and maintenance: Keep an eye on installation space and maintenance paths. For example, a bathtub should be at least 10 cm (about 4 inches) from the wall for future maintenance and cleaning.
Once you’ve evaluated the space, you can choose the right size bathtub to suit your appeal. Look at some bathtub designs to help you make the right decision.
Small Bathroom Bathtub Ideas
There are a lot of options for homeowners who want to embrace an elegant freestanding bathtub in their small bathroom.

● Vintage Freestanding Tubs: Freestanding tubs are typically placed against a wall, under a window, or at the center of the room.
When floor space is limited, consider positioning the tub in the kitty corner. A solid-surface bathtub can be angled to fit snugly against a window, providing a nice room flow without appearing awkwardly tucked in the corner.
● Sleek Slipper Tubs: A slipper tub is an excellent solution in a tight space. Featuring one or two heightened ends, they allow for a reclined position, which means bathers can enjoy a deep soak in a small area.
The increased depth of slipper tubs offers plenty of water coverage without requiring more square footage.
● Compact Pedestal Tubs: Certain pedestal bathtubs are available in smaller sizes, offering a bowl that is both shorter and sufficiently deep to immerse yourself without any issues.
The models with a front apron that covers the entire tub circumference are useful because they extend to the floor and make for no inaccessible area beneath the bath.
● Innovative Shower Room: Japanese-inspired design has particularly taken to the trend of putting the tub in the shower.
When you have to tiptoe around a slim, soaking wet, freestanding bathtub to shower, that’s a struggle many prefer to live without.
With a glass wall separating the shower and tub from the rest of the bathroom, these walk-in baths and showers look bigger and more luxurious than your standard tub and shower.
● Japanese Soaking Tubs: Embraced by the Japanese for centuries, the deep-soaked Japanese tub boasts an immersive bathing experience.
Compared to standard tubs, its deeper basin allows a seated bather to submerge up to their chin completely.
Some come with built-in seats, letting you enjoy a full soak while conserving water. The compact size of Japanese soaking tubs makes them a fitting, water-conserving choice in locales like San Diego, where water costs can be high.
The types mentioned here fit perfectly into your small bathroom space, maintaining its integrity and elevating its elegance.
Installing the Bathtub
Once you have decided on the bathtub design, you can easily fit a freestanding bathtub in your small bathroom.

Installing a bathtub will take a while, as it requires patience and expertise. Let’s look into the steps below that highlight the process of how to fit a bathtub:
When installing the new tub, use shims to align the flange and drains with your fixture. Dry-fit the plumbing components, including the drain and drain shoe, before final placement, making the process smoother by completing most of it beforehand.
Don’t worry about how to install a bathtub drain. You can simply secure the drain and apply a generous bead of caulk around the tub’s perimeter. After that, just reattach the faucet to complete the installation.
Fill the new bathtub and check for water leaks, ensuring that mortar, caulking, or plumber’s putty has a full 24 hours to set. It’s crucial to wait until the materials are completely cured before conducting the water tightness test.
As part of the final steps in the bathtub installation process, the sink and toilet will be reinstalled, and any necessary drywall and tiles will be replaced.
Small Bathroom Bathtub Installation Tips
Overcoming the challenges of a small bathroom with a bathtub involves strategic planning and creative solutions. To maintain the functionality and aesthetics of your limited space, keep some following important tips in mind.
● Opt for Compact Elements: Efficiently design the layout by choosing compact built-in bathtubs or freestanding options like free-standing bathtubs with feet.
Position them in corners to maximize space, providing both functionality and aesthetics. You can use your freed-up space to install any other functional element.
● Utilize Sloped Ceilings: If your bathroom is in the attic with a low ceiling, consider installing the bathtub in this area. Low vertical space is ideal for this purpose, creating a practical and visually appealing solution.
● Embrace Corner Installations: In square bathrooms, enhance the sense of space by installing bathroom fittings in corners. This strategic placement not only clears up the central area but also gives the illusion of a larger bathroom.
● Harness Colors and Light: Combat the perception of limited space by using light-colored wall cladding and maximizing natural and artificial light sources.
These techniques visually expand the space, creating a brighter and more open atmosphere in your small bathroom with a bathtub.
