Why Choose a Cast Iron Bath?
Cast iron is naturally resistant to chipping, cracking and everyday wear, and with proper care a cast iron bath can easily outlast the bathroom around it. The dense metal shell also holds heat far more effectively than acrylic, meaning your bath water stays warmer for longer and lets you properly relax and unwind.
Style wise, cast iron baths suit everything from period cottages to modern new-builds, ranging from classic freestanding silhouettes to more contemporary slipper shapes, and can be paired with traditional or contemporary bath taps to complete the look. Our Heritage Bathrooms cast iron baths are enamelled twice for a smooth, durable finish, so you get showroom-quality looks at a genuinely competitive price.
Choosing the Right Cast Iron Bath
Before you buy, it's worth thinking through a few practical details. A full-size cast iron bath typically weighs between 150-200kg empty, and considerably more once filled and in use, so always check your floor structure can support the load, particularly in upper-floor bathrooms or older properties. A qualified builder can confirm this for you.
Our range is available with two tap holes for deck-mounted taps, or with no tap holes if you'd prefer to install wall-mounted or freestanding bath taps instead. Cast iron baths are usually raised on decorative ball-and-claw or bracket feet, available in a range of finishes to match your existing brassware. And if your bathroom can't accommodate a freestanding footprint, a freestanding bath in acrylic or steel may be a more practical alternative while still delivering a similar traditional look.
Cast Iron vs Acrylic vs Steel Baths
Cast iron, steel and acrylic baths all have their place. Acrylic is the lightest and most affordable option, ideal where floor loading is a concern. Steel baths sit in the middle, offering good durability and heat retention at a lower weight than cast iron.
Cast iron remains the benchmark for heat retention and longevity, making it the natural choice for anyone prioritising authenticity and long-term durability over installation convenience.
Frequently Asked Questions
What is a cast iron bath made from?
A cast iron bath is cast from molten iron and then coated with several layers of vitreous enamel, a glass-like coating fused to the metal at high temperature, which gives the bath its smooth, hard-wearing surface.
How heavy is a cast iron bath, and will my floor take the weight?
An empty cast iron bath typically weighs 150-200kg, considerably more once filled with water and a bather. Most ground-floor bathrooms with a solid subfloor cope without issue, but for upper floors it's worth having your floor joists checked by a builder before installation.
Do cast iron baths keep water hot for longer than acrylic baths?
Yes. The dense metal retains heat significantly better than acrylic, so your bath water stays warmer for longer once it's been run.
How long does a cast iron bath last?
With reasonable care, a quality enamelled cast iron bath can last many decades. Many period properties still have their original cast iron bath in daily use.
