Model numbers for your Kingston Brass Products can be located in several different locations. Most sales receipts, order details, or invoices will contain the model number of your Kingston Brass product. The model number will also be located on the exterior packaging of your Kingston Brass product just above the barcode. Kingston Brass model numbers are alphanumeric, beginning with several letters followed, by a series of numbers, and ending with several more letters. (For example KS7798ALBS)

Kingston Brass bathtubs come in three materials: acrylic, cast iron, and solid surface. Acrylic tubs offer the greatest economy and ease of install. Acrylic involves a three-layer process. First, the fiberglass substrate is formed, then a layer of high-grade acrylic sheeting is bonded to the substrate, and finally, the acrylic receives a coat of sealant to protect the finish and color for years to come. 

Cast iron bathtubs are formed in vacuum molds, then sealed and finished with white enamel to create high quality, extremely durable finish. Cast iron offers the best heat retention and durability of any tub material, but it is also exceedingly heavy.

Solid surface is a composite material that incorporates high-quality resin, aluminum, and mineral powder to form a durable, resurfaceable bathtub. Kingston offers solid surface tubs in a matte white exterior with gloss white interior as well as a matte grey exterior with gloss white interior. The matte exterior provides high style and design and the gloss interior ensures the tub remains easy to clean and maximizes stain resistance over time.

Our cast iron bathtubs product has been tested for lead content, and its outer paint coating has also been tested for both lead and phthalates with results as follows:

Lead levels are all below detectable limits per testing technology available. Functionally and legally, the tub is lead-free. This means that appropriately installed and used it does not expose anyone to lead or other chemicals known to the state of California to cause cancer, reproductive harm, or birth defects.

The concern over lead content in bathtubs is usually associated with older cast iron tubs (over 20-30 years old) that did use lead in the enamel and have had the enamel coating damaged or had the coating break down with advanced age and use thus exposing the old enamel which can contain lead. A side note of interest - even an antique tub with degraded coating can be restored and used safely. The enamel simply needs to be repaired and the tub surface resealed with an appropriate sealant product.

The overall list of checkpoints:

1. Size - how long is your tub dimension in your bathroom?

2. Material - cast iron form or acrylic formation?

3. Drain Type - Toe Touch, Lift and Lock, or Standard Drain?

4. Location - against wall or freestanding, floor level, pipe direction, and etc.

5. Style - Modern, Traditional, or Transitional?

Categories Include: Freestanding Bathtubs and Pedestal Bathtubs

This is not a manufacturer defect or problem with the bathtub itself. The cause is usually that the tub is not level.  The water is pooling in the corner or one side because the bathtub is A) not level on all 4 corners B) doesn’t have the required mortar base installed correctly C) has an uneven subfloor or D) it was not installed properly according to the instructions.  To fix this problem you must re-install the bathtub, apply the correct amount of mortar base for the tub to rest in, and then level all 4 sides and corners of the bathtub prior to securing it to the wall or surrounding. Once the tub is secured, re-level again prior to the mortar base curing.

Our Kingston Brass tubs go through rigorous testing, so that we can provide our customer with not just the finest quality, but also a healthy choice for your way of life.

Below is a summary of the testing report:
Intertek Testing Services Taiwan Limited – a certified 3rd party lab (CAL Prop 65)
Only brass feet made of brass alloy come with lead.

Tub Breakdown below
The prop65 test result : Passed
Cast Iron -Lead < 10 ppm (mg/kg) Passed
Enamel -Lead < 10 ppm (mg/kg) Passed
Exterior -Paint (on the back side of tub)--- lead < 10 ppm (mg/kg), phthalate < 1000 ppm (0.01%) Passed

Conclusion:
Lead is lower than 10 ppm.

All Test Machines cannot detect any lead over 10ppm.

Brass

Brass is an alloy composed primarily of copper and zinc that may also contain small amounts of other metals. These additional constituents give the brass specific qualities for particular applications and vary by use of the end product. Overall, as a material brass is highly corrosion-resistant, extremely durable, and has greater workability than materials like stainless steel. This is to say, it lends itself well to forming into more detailed shapes for products like faucets and console vanity legs. Additionally, brass is a recyclable material and even has scrap value at the end of the service life of the finished product.

Stainless Steel

Stainless steel is a ferrous (iron-based) alloy with at least 10.5% chromium to provide oxidation resistance. Stainless steel is rust and corrosion resistant, highly durable, and offers excellent structural strength. Stainless steel offers these qualities at a lower weight than a comparable item manufactured from a material like brass. Finally, stainless steel can be recycled at the end of the product’s lifecycle. Unfortunately, the scrap or recycle value for stainless steel is quite low, but at the very least it does not have to go into a landfill.

Acrylic

Acrylic is a clear, high-density polymer that is typically used as an accent material, such as on our line of crystal doorknob-inspired faucet handles. Acrylic can also be used as a primary structural material such as in our acrylic console vanity legs, but these applications are less common. The material itself offers the transparent qualities of glass and crystal without the same risk of cracking or shattering - and in the case of crystal without any added hazardous constituents like lead. Unfortunately, recycling acrylic is quite difficult and may not be available in all jurisdictions. Once your acrylic product has reached the end of its life, please contact your local waste management authority to determine what options there are for appropriate and responsible disposal. 

Ceramic and Vitreous China

Ceramic and vitreous china are frequently used interchangeably, but they are ever so slightly different from one another. Both materials are composed of a mineral clay base that is formed and fired to harden it. Both materials are then coated with a glass-based glaze and fired again to create a non-porous, glossy surface. Both materials are extremely durable and easy to maintain. So what’s the difference? Vitreous china is a slightly finer clay base, and it fires at a slightly higher temperature than conventional ceramic. When a ceramic or vitreous china fixture reaches the end of its life, it can be taken to a recycling center that accepts ceramics and porcelain, or it may need to be taken to a company that specializes in construction fill or reclaimed materials where it will be broken up and repurposed as construction backfill or the like, rather than being dumped. Please consider doing a bit of research and responsibly disposing of your old fixture before sending it to the landfill.

Porcelain

Porcelain is a close relative of ceramic and vitreous china. It is also composed of mineral-based clay and undergoes a firing process at high temperatures. Unlike ceramic or vitreous china, porcelain is non-porous after its first firing, so it does not require a glaze to be applied to achieve a glossy, easy-to-clean surface. Like ceramic and vitreous china, when discarding porcelain it can be taken to a recycling center that accepts ceramics and porcelain, or it may need to be taken to a company that specializes in construction fill or reclaimed materials where it will be broken up and repurposed as construction backfill or the like, rather than being dumped. Please consider doing a bit of research and responsibly disposing of your old fixture before sending it to the landfill.

Solid Surface

Solid surface, also called Solid Surface White Stone, is a new material on the market compared to materials like cast iron and ceramic that have been in use for hundreds (or even thousands) of years. Solid Surface consists of a composite of metal and mineral powders and high-grade resin. The resulting material exhibits a number of unique characteristics. It weighs less than cast iron or natural stone, and it retains heat better than acrylic. Matte solid surface can have minor scratch and stain damage repaired by the owner, and polished glossy solid surface can have minor scratch and stain damage repaired by a professional, so it is an unusually forgiving material even though it possesses a very fine surface.

Cast Iron

Cast Iron is another extremely long-standing material in plumbing fixtures. Most commonly found in sinks and bathtubs, but also used in accessories, handles, and other products, cast iron provides excellent durability and heat retention. Cast iron sinks and bathtubs are formed in a vacuum mold process, then coated with high-grade enamel for an exceptionally long-lasting and easy-to-care-for product. Expect a cast iron fixture to last decades or more. Kingston’s cast-iron fixtures are tested and certified to contain less than 10ppm lead (lowest detectable concentrations) in the iron substrate, the enamel finish, and the exterior paint, so feel confident you’re getting clean in a clean bathtub.
