Understanding Bathtub Types

The first step in selecting your ideal bathtub is to understand the different types available, as each offers unique installation requirements, aesthetic appeals, and functional benefits. The choice of type often dictates the overall layout and design of your bathroom.

Freestanding Tubs

Freestanding bathtubs are standalone fixtures that are not attached to any walls, offering a luxurious and sculptural focal point in a bathroom. They come in various styles, from classic claw-foot designs to sleek, modern shapes. Their versatility in placement allows for creative bathroom layouts, making them a popular choice for those seeking a high-end, spa-like ambiance. However, they typically require more floor space and can be more challenging to install due to plumbing considerations that need to be routed through the floor.

Alcove Tubs

Alcove bathtubs are the most common type, designed to be installed in a three-wall enclosure. They are highly space-efficient and are often found in standard bathrooms, serving as a shower-tub combination. These tubs are practical, cost-effective, and easy to install, making them a popular choice for families and those with smaller bathrooms. They usually feature an unfinished side that is meant to be tiled or covered by a tub surround.

Drop-in Tubs

Drop-in bathtubs are designed to be dropped into a framed enclosure or a custom-built deck. The rim of the tub sits flush with the surrounding deck, creating a seamless look. This type offers design flexibility, as the deck can be finished with various materials like tile, stone, or wood, allowing for a customized aesthetic that integrates well with the bathroom's decor. Installation can be more complex due to the need for a custom frame.

Corner Tubs

Corner bathtubs are designed to fit into the corner of a bathroom, maximizing space utilization. They are often larger than standard tubs and can come in various shapes, including triangular or rounded designs. Corner tubs can be a good option for bathrooms with unconventional layouts or for those who desire a more spacious bathing area without sacrificing too much floor space. They can be either drop-in or freestanding, depending on the model.

Walk-in Tubs

Walk-in bathtubs are specifically designed for accessibility, featuring a watertight door that allows users to step into the tub without having to lift their legs over a high rim. These tubs often include built-in seats, grab bars, and therapeutic features like hydrotherapy jets, making them ideal for seniors, individuals with mobility issues, or anyone seeking a safer and more comfortable bathing experience. While highly functional, they typically have a higher cost and require more time to fill and drain.

Bathtub Sizes and Dimensions

Understanding bathtub sizes and dimensions is crucial for ensuring a proper fit within your bathroom space and for achieving the desired bathing experience. Bathtubs come in a wide range of sizes, and selecting the right one depends on your bathroom's layout, available space, and personal preferences.

Standard Sizes

The most common standard bathtub size is approximately 60 inches (152 cm) long, 30 inches (76 cm) wide, and 14 to 16 inches (36 to 41 cm) deep. These dimensions are typical for alcove tubs and are designed to fit into most standard bathroom layouts. While these sizes are prevalent, variations exist, and it's always best to measure your available space accurately before making a purchase.

Small Bathtubs

For compact bathrooms or those with limited space, smaller bathtubs are available. These can range from 48 inches (122 cm) to 54 inches (137 cm) in length and may be narrower or shallower than standard tubs. Japanese soaking tubs, for example, are often shorter but deeper, allowing for a full body soak in a more upright position, making them an excellent space-saving option.

Large Bathtubs

If space permits and you desire a more luxurious bathing experience, larger bathtubs are an option. These can include extra-long tubs (up to 72 inches or 183 cm), wider tubs, or deeper soaking tubs. Large bathtubs are ideal for those who enjoy extended soaks, or for accommodating two bathers. However, they require significant floor space and may necessitate additional structural support due to their increased weight when filled.

Measuring Your Space

Before purchasing any bathtub, it is imperative to accurately measure your bathroom space. Consider the length, width, and height of the area where the tub will be installed. Also, account for door swings, vanity clearances, and any other fixtures that might impede the tub's placement or access. Don't forget to measure doorways and hallways to ensure the tub can be easily transported into the bathroom.

Exploring Bathtub Materials

The material of a bathtub significantly impacts its durability, heat retention, weight, maintenance requirements, and overall cost. Each material offers a unique set of advantages and disadvantages, making it important to choose one that aligns with your priorities and budget.

Acrylic Bathtubs

Acrylic bathtubs are one of the most popular choices due to their affordability, versatility, and lightweight nature. Made from vacuum-formed acrylic sheets reinforced with fiberglass, they are warm to the touch, retain heat well, and are available in a wide range of shapes, sizes, and colors. Acrylic is non-porous, making it resistant to mold and mildew, and relatively easy to clean. However, it can be prone to scratching and may show signs of wear over time if not properly maintained.

Cast Iron Bathtubs

Cast iron bathtubs are renowned for their exceptional durability, heat retention, and classic aesthetic. These tubs are made by pouring molten iron into a mold, which is then coated with a thick layer of enamel. The heavy mass of cast iron allows it to retain heat for extended periods, providing a long and luxurious soak. While highly resistant to chipping and scratching, cast iron tubs are extremely heavy, often requiring floor reinforcement and professional installation. They are also typically more expensive than acrylic or fiberglass options.

Porcelain-Enameled Steel Bathtubs

Porcelain-enameled steel bathtubs offer a more affordable alternative to cast iron while still providing a durable and glossy finish. They are made from a steel base coated with a layer of porcelain enamel. These tubs are lighter than cast iron but still offer good heat retention and are resistant to stains and scratches. However, the enamel can chip if a heavy object is dropped on it, exposing the steel underneath, which can lead to rust if not repaired promptly.

Fiberglass Bathtubs

Fiberglass bathtubs are among the most inexpensive and lightweight options available. They are constructed from fiberglass reinforced plastic, often with a gel-coat finish. While easy to install and suitable for multi-story homes due to their light weight, fiberglass tubs are less durable than acrylic or cast iron. They are more susceptible to scratching, fading, and cracking over time, and their porous surface can make them more challenging to clean and prone to staining.

Stone Resin Bathtubs

Stone resin bathtubs are a premium option, offering a luxurious look and feel, excellent heat retention, and exceptional durability. They are made from a blend of natural minerals and resins, resulting in a solid, non-porous surface that is warm to the touch and highly resistant to scratches and stains. Stone resin tubs are heavy, similar to cast iron, and often come in contemporary designs, making them a popular choice for high-end bathrooms. Their cost is typically higher than most other materials.

Copper and Wood Bathtubs

For a truly unique and distinctive bathroom, copper and wood bathtubs offer unparalleled aesthetic appeal. Copper tubs are known for their natural antimicrobial properties, excellent heat conductivity, and the ability to develop a beautiful patina over time. Wood tubs, often made from teak or cedar, provide a warm, natural feel and are surprisingly durable when properly sealed and maintained. Both options are at the higher end of the price spectrum and require specific care to preserve their beauty and integrity.

Bathtub Features and Functions

Beyond basic functionality, modern bathtubs offer a variety of features and functions designed to enhance your bathing experience, turning a simple soak into a therapeutic or luxurious ritual. When selecting a bathtub, consider which of these features align with your relaxation and wellness goals.

Soaking Tubs

Soaking tubs are designed for deep immersion, allowing the bather to be fully submerged in water. They are typically deeper than standard bathtubs, often ranging from 18 to 24 inches (46 to 61 cm) in depth. The primary focus of a soaking tub is relaxation and comfort, providing a serene environment for unwinding after a long day. They can be found in various styles, including Japanese soaking tubs and freestanding designs.

Whirlpool and Jetted Tubs

Whirlpool and jetted tubs incorporate a system of jets that release streams of water, often mixed with air, to create a massaging effect. These tubs are popular for their therapeutic benefits, helping to soothe sore muscles, reduce stress, and improve circulation. Whirlpool tubs typically have fewer, larger jets that create a powerful, directed massage, while jetted tubs (sometimes called air jets) have numerous smaller jets that produce a gentler, effervescent sensation. Maintenance involves regular cleaning of the jet system to prevent mold and mildew buildup.

Air Tubs

Air tubs, also known as air bubble massage tubs, use a blower to push heated air through dozens of small holes located at the bottom of the tub. This creates thousands of gentle, effervescent bubbles that envelop the bather, providing a soft, full-body massage. Unlike jetted tubs, air tubs do not recirculate water, making them more hygienic and easier to maintain. They are an excellent choice for those who prefer a gentle, calming massage over a vigorous one.

Heated Bathtubs

Heated bathtubs come with built-in heating elements that maintain the water temperature, allowing for extended soaks without the water cooling down. This feature is particularly beneficial for those who enjoy long, leisurely baths or for therapeutic purposes where consistent water temperature is desired. Some heated tubs also offer chromotherapy, a feature that uses colored lights to create a calming or energizing ambiance.

Chromotherapy and Lighting

Chromotherapy, or color therapy, involves the use of colored lights to promote relaxation and well-being. Many modern bathtubs integrate LED lighting systems that can cycle through various colors or be set to a specific hue. This feature can enhance the bathing experience by creating a desired mood or atmosphere. Some tubs also include underwater lighting for aesthetic appeal and safety.

Factors to Consider Before Buying

Before making a final decision on your new bathtub, several key factors should be carefully considered. These considerations will help ensure that your chosen tub not only fits your space and budget but also meets your long-term needs and preferences.

Budget

Bathtub prices vary widely depending on the type, material, size, and features. Fiberglass and acrylic tubs are generally the most affordable, while cast iron, stone resin, copper, and wood tubs represent higher-end investments. Beyond the purchase price, remember to factor in installation costs, which can vary significantly based on the tub type and any necessary plumbing or structural modifications.

Durability and Maintenance

Consider the long-term durability of the material and the maintenance required to keep your tub in pristine condition. Materials like cast iron and stone resin are highly durable and resistant to wear, but may require specific cleaning products. Acrylic and fiberglass are easier to clean but can be more prone to scratching and staining. Understanding the maintenance needs upfront will help you choose a tub that fits your lifestyle.

Heat Retention

For those who enjoy long, hot baths, heat retention is a critical factor. Cast iron, stone resin, and some acrylic tubs offer excellent heat retention, keeping the water warm for extended periods. Materials like fiberglass and steel may lose heat more quickly, requiring more frequent hot water additions to maintain a comfortable temperature.

Installation Requirements

The installation requirements for different bathtub types can vary significantly. Alcove tubs are generally the easiest to install, while freestanding and drop-in tubs may require more complex plumbing work and custom framing. Heavy materials like cast iron or stone resin may necessitate floor reinforcement. It's advisable to consult with a professional plumber or contractor to understand the installation complexities and costs associated with your chosen tub.

Aesthetic and Style

The aesthetic appeal of your bathtub should complement your bathroom's overall design and your personal style. From traditional claw-foot tubs to sleek, contemporary designs, there's a bathtub to suit every taste. Consider the color, shape, and finish of the tub, as well as how it will integrate with other bathroom fixtures and decor elements.

Installation Guide Overview

While professional installation is often recommended for bathtubs, especially for complex types like freestanding or jetted tubs, understanding the general steps involved can help you prepare and communicate effectively with your installer. This overview provides a simplified guide to the typical installation process.

Preparation: Ensure the bathroom floor is level and capable of supporting the tub's weight when filled. Verify that all necessary plumbing connections (water supply and drain) are in place and easily accessible.
Placement: Carefully position the bathtub in its designated location. For alcove tubs, ensure it fits snugly against the three walls. For freestanding tubs, consider optimal placement for both aesthetics and plumbing access.
Leveling: Use shims or adjustable feet to ensure the tub is perfectly level. This is crucial for proper drainage and stability.
Plumbing Connections: Connect the drain assembly to the tub's drain opening and then to the main drainpipe. Connect the water supply lines to the faucet fixtures. Ensure all connections are secure and watertight to prevent leaks.
Securing the Tub: Depending on the tub type, secure it to the wall studs (for alcove tubs) or to the floor (for some freestanding tubs) using appropriate fasteners. This prevents movement and ensures stability.
Finishing Touches: For drop-in tubs, complete the surrounding deck or enclosure. For alcove tubs, install wall surrounds or tile the walls. Apply caulk around the edges of the tub where it meets the walls or floor to create a watertight seal.
Testing: Fill the tub with water and check for any leaks around the drain and water supply connections. Test all features, such as jets or heaters, if applicable.

Maintenance and Care Tips

Proper maintenance and care are essential to prolong the life of your bathtub and keep it looking new. The specific care instructions may vary depending on the material of your tub, but some general guidelines apply to all.

Regular Cleaning: Clean your bathtub regularly with a non-abrasive cleaner and a soft cloth or sponge. Avoid harsh chemicals, abrasive scrubbers, or steel wool, as these can damage the tub's surface, especially for acrylic and fiberglass.
Prevent Stains: Rinse the tub thoroughly after each use to prevent soap scum and mineral deposits from building up. Address any stains promptly to prevent them from setting in.
Avoid Heavy Objects: Be careful not to drop heavy or sharp objects into the tub, as this can cause chips, cracks, or scratches, particularly on porcelain-enameled steel and fiberglass.
Maintain Grout and Caulk: Regularly inspect and clean the grout lines and caulk around your tub. Re-caulk as needed to prevent water leaks and mold growth.
Special Care for Materials:
- Cast Iron: Use mild, non-abrasive cleaners. Avoid acidic cleaners that can dull the enamel.
- Acrylic/Fiberglass: Use cleaners specifically designed for these materials. Avoid acetone-based products.
- Stone Resin: Clean with mild soap and water. For stubborn stains, a fine-grit sandpaper can sometimes be used, followed by polishing.
- Copper: Clean with mild soap and water. Avoid abrasive cleaners. Copper will naturally patina over time, which is part of its charm.
- Wood: Ensure the wood is properly sealed and maintained according to the manufacturer's instructions to prevent water damage and warping.
Jetted Tubs: Follow the manufacturer's instructions for cleaning the jet system. This usually involves running a cleaning solution through the jets periodically to prevent bacterial buildup.
