Types and Sizes of Bathtubs

Bathtubs are not created equal.  Substrate-wise, there are 4 different types of material that can be used in manufacturing a bathtub:  porcelain, acrylic, fiberglass, or cultured marble.    


A porcelain tub has a base of either steel or cast iron, and is the most common type of bathtub found in homes built before the 1970s.  A "standard" size porcelain tub is in the shape of a 5 foot rectangle, and is usually surrounded by 3 walls of tile or other material that is separated by a caulk line.  


Acrylic and Fiberglass bathtubs can also be this same standard size, but they can also be oversized (like a garden tub), or part of a wall unit where the tub and the surrounding walls are all one piece of material, not separated by a caulk line.


Cultured Marble bathtubs are typically oversized, and almost always found in a Master bathroom.  These types of tubs are can be jetted, and have steps, ledges, and shelves.

Also send measurements.  For length and width, measure straight across the tub (don't dip down into the tub).  For height, put the measuring device on the bathroom floor next to the tub and measure straight up vertically. 

Repair Work Prior to Refinishing

If there is damage in a bathtub, all of it must be repaired before the bathtub can be refinished.  Some porcelain bathtubs are manufactured with anti-slip bottoms that have been sandblasted into the porcelain finish.  Because of that, this particular section of the porcelain develops pinholes, pock marks, and dimples that may or may not be seen with the naked eye.  However, once we start to spray on the new finish, these flawed areas begin to appear.  To help reduce this problem prior to refinishing, we fill in these flawed areas with Bondo to build them up, then gently sand them smooth as part of the prep phase.  We call this process "skinning" the tub, and it is part of the repair process.


Please note our warranty is specifically related to the two things under our control:  workmanship and product defects.  We do not guarantee that rust, cracks, or holes won't reappear later in a bathtub if the underlying source of the damage (possibly a house shift, improper initial installation, water leak, or previous damage to the same area) has not been corrected.
