The term refers to a toilet model specifically designed to fit plumbing configurations where the distance from the finished wall to the center of the drainpipe is approximately nine inches. This measurement, crucial for proper toilet installation, dictates the selection of a compatible fixture. These toilets are commonly available at major home improvement retailers. For instance, in older homes or specific remodeling scenarios, space constraints might necessitate the use of a toilet with this particular drain-to-wall measurement.
Choosing a toilet that corresponds with the existing plumbing’s drain-to-wall distance is essential for a seamless and cost-effective installation. Ignoring this specification can lead to significant plumbing alterations, increasing both time and expense. Such models provide a solution for bathrooms with limited space or pre-existing plumbing configurations that deviate from the standard 10-inch or 12-inch rough-in dimensions. Their availability allows homeowners and contractors to find the necessary fixtures to complete bathroom projects without major renovations.
