The best material for bathtub depends on who is buying
A good recommendation starts with the buyer, not the product sheet.
First-time homeowners who want value and easy maintenance
New homeowners want something budget-friendly, easy to maintain, and lightweight. In this case, you can suggest fiberglass tubs and acrylic as suitable options to these shoppers. However, what makes acrylic stand out is its resistance to wear and tear and its extended lifespan.
Families who want a durable, easy-to-clean bathtub
For families, durability and long-term maintenance are top priorities when choosing bathtubs. Here, cast iron and acrylic perform better than other types, although cast iron is more affordable. Cast iron resists scratches and lasts as long as the house, while acrylic doesn’t absorb water, soap, or stains.
Premium buyers shopping for a freestanding bathtub or soaking tub
Buyers in this category want long-lasting and luxurious materials. So, a popular choice is stone resin, which delivers a high-end look
Property managers and landlords who care about cost and replacement cycles
Landlords and property managers focus on ease of replacement and upfront cost. These categories of buyers are more likely to pick fiberglass and enameled steel. However, steel offers more long-lasting value than fiberglass without a huge price jump.
Buyers looking for walk-in tubs or low-entry options
Buyers looking for walk-in tubs or low-entry options often prioritize safety and accessibility. In this category, acrylic outperforms others because it’s lightweight and easy to customize into designs.
The 4 bathtub materials buyers compare most
When stocking, most sellers compare acrylic, cast iron, enameled steel, and stone resin bathtubs. This is because of their weight, affordability, maintenance, and installation process.
1. Acrylic bathtub
Acrylic bathtubs are made from molded plastic and reinforced with fiberglass. Many business buyers favor these fast-selling materials because they’re affordable, lightweight, and easy to install. It also retains heat longer and is resistant to chipping.
2. Cast iron bathtub
Cast iron tubs are made from molten iron that’s poured into a mold and coated with a thick layer of porcelain enamel. They are strong, long-lasting, and hold heat longer than other materials. However, they weigh heavily and can be extremely expensive.
3. Enameled steel bathtubs
Enameled steel bathtubs are made from steel coated with porcelain enamel. On the surface, they look similar to cast iron, but they’re lighter and more affordable. However, they chip easily, and this can make them prone to rust.
4. Stone resin bathtub
Stone resins are made from a combination of crushed natural stone (marble or limestone) and synthetic resin binder. This helps to give them a solid, luxurious finish. While they’re durable and aesthetically pleasing, they can be quite heavy.
Short comparison notes on the different materials
Acrylic is the most preferred option for its durability, price, and versatility. Cast iron is also durable but offers the longest lifespan of all four bathtub materials. Steel is a cost-saving option, but it’s not as durable as cast iron. Lastly, stone resin works well for buyers seeking luxurious bathtubs and adds visual appeal in a showroom.
What buyers usually ask before they purchase
Buyers often ask many questions when making a purchase. Your knowledge of these materials and your ability to answer customers’ questions satisfactorily determine whether a sale moves forward or stalls. Here are some commonly asked questions:
1. What is the longest-lasting bathtub?
Of all the different bathtub types, cast iron lasts the longest because it’s made by pouring molten iron into a mold. It has great longevity with very minimal wear or rust. This makes it suitable for frequent use and temperature changes without the need for replacement. Stone resin follows closely and can last between 20 and 30 years. Note that acrylic’s long-lasting value depends on its quality and usage.
2. What bathtubs do not scratch easily?
Cast iron is a top performer because its enamel coating makes it extremely hard to scratch off. It’s also highly resistant to dents and daily wear. Stone resin follows closely because of its mineral and resin blends, which are harder to scratch and don’t wear easily under daily use. Enameled steel comes last on this list because of its porcelain coating, which resists scratches fairly well.
3. Is acrylic good for bathtub use?
Acrylic is a strong choice for everyday bathtub use because it’s affordable, durable, and easy to maintain. It doesn’t chip easily, absorb water, or stain. It’s also lightweight, easy to install, and moldable into various designs.
4. Do acrylic tubs turn yellow?
Acrylic tubs can turn yellow over time only if they’re of lower quality. Also, bathrooms with large windows that let in direct sunlight can contribute to this discoloration. Harsh cleaning products can also cause discoloration to set in faster. However, acrylic made from high-quality materials will retain its color for a long time.
5. Which tub holds warm water longer?
Cast iron leads the way here as it can retain heat for up to 60 minutes before noticeable cooling. However, this means it also takes time to warm up. Stone resin follows cast iron, with heat retention lasting 20 to 40 minutes. It also warms up faster than cast iron. Lastly, acrylic can retain heat for up to 30 minutes.
6. Which material feels premium instead of cheap?
Stone resin comes first when considering luxury-feeling options. This is due to their heavy build, smooth finish, and high-end look. Cast iron comes next on the list because of its heavy structure, enamel surface, and durable feel. Acrylic might not look as premium, but it can also have a nice appearance if it’s made from high-end materials.
7. Which type needs the least maintenance?
Of all the bathtub materials, acrylic requires the least maintenance. This is because it’s non-porous and can be cleaned without special products. Also, because it doesn’t hold moisture, it’s less likely to develop mold.
Stocking the right bathtub material to gain more sales
Understanding the different bathtub materials and who they’re best suited for goes a long way toward helping your business build a reliable bathtub line. While products like acrylic bathtubs sell faster due to their affordable pricing, cast iron and stone resin bathtubs generate higher-margin sales because they’re sought after by premium clients. Don’t forget to include fiberglass and steel as budget options, but don’t overstock them.
Above all, study what your buyers actually prioritize the most. When you do so, you can easily source the best material for bathtub from trusted suppliers from a trusted platform like Accio, an AI-powered B2B sourcing platform that connects small businesses with suppliers selling quality products.
