About This Product

Indulge in the soothing comfort of the 63'' Streamline Cast Iron R5581CH Drop In Bathtub With External Drain. Designed with a drop-in style in mind for easy installation and a chrome external drain for style and practicality, this bathtub is all you have been dreaming of. And when it comes to quality, this 63 inch drop-in bathtub meets and excels our expectations. It is made from durable cast iron material that promises to keep the surface untouched for many years to come. And of course, you don't have to worry about water fill because the 63'' Streamline Cast Iron R5581CH Drop In Bathtub With External Drain can hold up to 42 gallons of water.


  • Overall Exterior Dimensions: 63.0 in. Length x 29.5 in. Width x 21.7 in. Height
  • Interior Soaking Dimensions: 43.3 in. Bottom Length x 15 in. Bottom Width x 13 in. Soaking Height
  • Our cast-iron material is melted and integrally formed at a high temperature. Cast-iron is resistant to compression and deformation and will retain its pristine form for more than 50 years with proper maintenance.
  • The bottom of each bathtub has a non-slip surface which is then sandblasted to integrate it into the bathtub. Doing so makes the bathtub look both aesthetically beautiful and safe when stepping in and out of the bathtub to bathe.
  • The porcelain-enamel that is used is imported from Germany, and is sprayed with 3 layers of enamel that is each 2mm thick. Doing so creates a bathtub that is easy to clean, will not discolor nor crack, while creating acid, alkali and scratch resistance.
  • Porcelain-enameled cast iron allows for maximum heat retention to enjoy baths for longer periods of time
  • The sheer thickness of our cast-iron bathtubs creates sound dampening properties. When water is filling the tub, the sound of water flow is minimal and absorbed, reducing disruption of the ambience in your bathroom.
  • The bathtub design that is implemented in our bathtub models mimics a humanized backrest slope, making every bath feel comfortable while resting in a natural position.
  • This bathtub comes with an external drain that includes a polished chrome pop-up drain. If this is not the drain color that you are looking for, please contact our support team for assistance.
  • There is NO deck mount faucet capability for this bathtub. A wall-mount or freestanding tub filler will be required to be used with the bathtub
  • This bathtub does have an overflow opening that is pre-drilled on the bathtub.
  • This bathtub has an effective bathing capacity of 42.3 gallons
  • This cast-iron bathtub comes with a 3 year limited manufacturer's warranty. For further details, please navigate to the documents section of the listing.
