3. Kingston Brass Aqua Eden Cast Iron Double Slipper Clawfoot Bathtub

Read Reviews & Best Deal ➜

I must say that this is a very beautiful and stylish bathtub with an oil-rubbed bronze finish and elegant brass details. However, after using it, I found that it has a design flaw that affects its practical use.

The problem is with the size and placement of the overflow hole. It is too big and too low, which means that the tub wastes at least 1.5 inches of height that could be used to hold water. As a result, when I soaked in the water, the level reached the lower part of the overflow and started running out of the tub. This is because the diameter of the overflow is even bigger than the bottom flow, and it cannot move up even an inch to compensate for the water loss.

On the positive side, I must admit that this is a very gorgeous and well-made bathtub. Its oil-rubbed bronze finish looks stunning, and the quality of the materials is excellent. I was very pleased with its beauty and quality, but unfortunately, its design flaws affected my overall satisfaction.


  • Beautiful and stylish design with an oil-rubbed bronze finish and elegant brass details
  • High-quality materials and construction


  • Design flaw with the size and placement of the overflow hole, which wastes at least 1.5 inches of height and makes the tub less practical than its size suggests
  • The fix for the overflow problem may require an adapter

Overall, while the Kingston Brass Aqua Eden Cast Iron Double Slipper Clawfoot Bathtub looks stunning, its design flaws affect its practical use, and I would only recommend it for those who prioritize beauty over function.

Features to Look for in a Cast Iron Bathtub

When shopping for a cast iron bathtub, here are some features to consider:

Clawfoot Design

Do you want a traditional and elegant look for your bathroom? Then consider a clawfoot cast iron bathtub. They have been around for centuries and are still popular today, providing a stylish touch to any bathroom.

Drain Location

There are three options for drain location: center, left side, or right side. If you plan on using your tub for bathing children or pets, the center drain is ideal. If you have limited space in your bathroom, choose a left or right drain.

Faucet Holes

Depending on whether you plan to add a shower head accessory later on, choose a 2-hole or 3-hole faucet for your cast iron tub. This is especially important if you want to use your tub as an all-purpose bathroom fixture.

Quick Installation

Cast iron tubs are easy to install and typically come with everything you need, except for the wallboard anchors that may be required by your local code requirements.


Cast iron bathtubs are heavier than other types of tubs, which can make it challenging to move them to another bathroom or house in the future.

Benefits of a Cast Iron Bathtub

There are numerous benefits to owning a cast iron bathtub, including:


Durability is one of the most significant factors to consider when choosing a cast iron bathtub. As previously mentioned, cast iron is known for its toughness and long-lasting performance, making it the ideal material for bathtub construction. Unlike acrylic, fiberglass, or other bathtub materials, cast iron is less prone to chipping, scratching, or cracking, making it a reliable option for those who want a bathtub that can withstand years of use.

The enamel coating on cast iron bathtubs also contributes to their durability. The enamel layer, which is baked onto the cast iron, protects the tub from scratches and stains while adding to its longevity. This coating also makes the bathtub resistant to chemicals, making it easy to clean and maintain.

In terms of longevity, cast iron bathtubs have a reputation for lasting for decades. With proper care, a cast iron bathtub can last over 50 years, which is significantly longer than other bathtub materials.

In terms of maintenance, cast iron bathtubs require minimal upkeep. Regular cleaning with a mild cleaner and a soft cloth is enough to keep your cast iron bathtub in excellent condition. Additionally, because cast iron is such a durable material, it is less likely to develop leaks or cracks over time, which can be expensive to repair.

Heat Retention

Cast iron bathtubs are known for their excellent heat retention properties. This means that the bathtub can maintain the heat of the water for a longer period compared to other materials. This is particularly useful if you enjoy soaking in a hot bath for extended periods or if you live in a colder climate.

The thickness of the cast iron material helps retain heat. When you fill a cast iron bathtub with hot water, the metal absorbs the heat and radiates it back into the water, keeping it warm. In addition, cast iron tubs can retain heat for up to an hour after the water is drained.

Heat retention is important for those who enjoy a relaxing and comfortable bathing experience. It can help you unwind after a long day and also provide therapeutic benefits. So, if you are someone who loves taking long, hot baths, then a cast iron bathtub is the perfect choice for you.

However, it’s important to note that a cast iron bathtub may take longer to heat up initially, especially if it’s a large bathtub. This is because the thick material takes longer to heat up than other materials like acrylic or fiberglass.

To maximize heat retention, it’s recommended to use a high-quality bathtub heater or to insulate the bathroom walls and floor. You can also consider installing a bathtub shower wall, which will help keep the heat inside the bathtub area and prevent it from escaping into the rest of the bathroom.

Style Options

When it comes to style options, cast iron bathtubs are a popular choice because they can fit any design scheme. These bathtubs come in various styles, shapes, and sizes, as well as different paint colors that can make them a focal point in your bathroom.

One of the most popular styles is the clawfoot design, which has been around for centuries and still remains in demand. Clawfoot tubs come with feet that resemble animal claws, adding a vintage and elegant touch to any bathroom. They are available in different sizes, making it easy to find one that fits your bathroom perfectly.

For those who prefer a more modern look, there are sleek and contemporary designs that feature clean lines and minimalistic details. These tubs are perfect for creating a chic and sophisticated atmosphere in your bathroom.

Another popular option is the freestanding tub, which offers versatility and flexibility in terms of placement. These tubs are not attached to any wall, and therefore can be placed anywhere in your bathroom, giving you more options for arranging your space.

When choosing the style of your cast iron bathtub, keep in mind the other bathroom fixtures you have, such as the sink, toilet, and bathtub shower wall. You want to ensure that the style of your bathtub complements the rest of the room and creates a cohesive look. The best bathtub shower wall options can be found here, which can help tie your bathroom together in terms of style and design.
