US spending on behind the wall plumbing (BTW) products is projected to advance 4.6% annually through 2022. Rising single-family housing completions and consumer interest in adding bathrooms to existing homes will boost demand for BTW plumbing products. As more bathrooms are installed, more and longer pipe runs will be needed to connect these bathrooms to water supply and sewer lines, while more fittings and valves will be needed to direct and regulate fluid flows.
In addition to installing more bathrooms in residences, homeowners will add fixtures to kitchens and bathrooms to enhance convenience. Such amenities as island and prep sinks, pot fillers, his-and-her vanities, and showers with multiple showerheads will further promote demand for BTW plumbing products. All of these fixtures need pipe and fittings to connect them to existing water supply and sewer networks, and valves are needed to ensure that water is delivered to fixtures at the proper temperature.
This study will explore applications, products, and markets that are bolstering demand. Demand is presented in dollar value terms, as well as in unit demand for pipe fittings and fire sprinklers. The study also evaluates factors driving kitchen and bathroom remodeling spending growth and discusses key sales channels.

How does Freedonia conduct research?
This study analyzes the US market for behind the wall (BTW) plumbing products, which are defined as the pipes and related components of a pipe system used to carry water to and from supply and sewer mains and standpipes. Pipe and fittings visible to the user of a kitchen or bathroom are excluded from the scope of this study, as are the products used outside of a structure (such as water and sewer mains). Pipe and fittings in a basement or crawlspace are included in the scope of this study, even if they are visible and not technically “behind the wall”. Sprinkler heads, while also visible, are also included in the scope of this study.
How does Freedonia define product & market coverage?
Behind the Wall: The pipes and related components of a pipe system used to carry water to and from supply and sewer mains and standpipes.
Do-It-Yourself: An improvement and repair project performed directly by the homeowner, as compared to those projects completed by a contractor or construction professional.
Push-to-Connect: A method of connecting plumbing products to each other by using a pipe or fittings with threaded pipe, rather than connecting them by welding them together or by using special adhesives
Residential: Encompasses conventional single-family houses, multifamily structures (e.g., apartments), and manufactured housing.
Commercial: Consists of institutional buildings (e.g., healthcare and educational facilities, religious establishments); office and commercial structures (e.g., office buildings, retail establishments, hospitality facilities, warehousing and storage facilities not located on industrial sites, and other commercial structures such as banks and theaters); industrial facilities (e.g., manufacturing plants and associated offices); and other commercial structures such as airport and bus terminals, recreational buildings, police stations, fire stations, and prisons.
New Construction: Expenditures related to the construction of, and site preparation for, entirely new residential or commercial structures.
Improvements: Spending on additions, alterations, remodeling and renovations to add value or useful life to existing residential and commercial structures.
Repairs: Spending on incidental maintenance and repairs to preserve a property’s ordinary operating condition. Repairs exclude costs for services such as cleaning, landscaping, lawn maintenance, and trash and snow removal.
 "Supply & Demand of Behind the Wall Plumbing Products")
Supply & Demand
What is trade's role in this industry?
The vast majority of BTW plumbing products sold in the US in 2017 were domestically manufactured. This is not surprising, given that the US is geographically vast with thousands of building code jurisdictions, which means that it can be difficult for a non-US firm to make products for only a few localities. Domestic production will continue to account for the large majority of US BTW plumbing product demand in 2022.
In July 2018, the US government levied 25% tariffs on a wide range of Chinese-made products over concerns about that nation’s unfair trade practices. In the metal pipe and fittings segment, tariffs on copper, ductile iron, and galvanized steel pipe and fittings will also affect BTW plumbing products demand, as higher prices will cause US consumers to seek out cheaper goods. However, the effects of these tariffs will be somewhat muted due to factors like metal plumbing pipe imports being fewer than plastic pipe imports because it is impractical to ship heavy metal pipes (especially ductile iron pipe) long distances.
What are historical market trends for behind the wall plumbing?
US demand for BTW plumbing products fell sharply between 2007 and 2009, and declined further in 2010 and 2011 as commercial construction spending dropped sharply. This reduced demand for pipe, fittings, and other products typically used to outfit these structures’ kitchen and bathroom facilities. However, during this period, BTW plumbing products demand in value terms did not fall as rapidly as between 2007 and 2009 due to:
- Rising metal prices that supported value demand for metal BTW plumbing products
- Increases in plumbing pipe pricing as firms shifted production capacity to the manufacture of pipe used in oil and gas drilling applications to meet demand resulting from a boom in exploration activity
Key Findings
- BTW plumbing demand is expected to rise 4.6% annually to $13.5 billion in 2022.
- An expected shortage of skilled plumbers will promote demand for easy-to-use products, such as PEX pipe and PTC fittings.
- More bathrooms will be added to residences as older homeowners undertake renovations to facilitate “aging-in-place.”
- Imports of BTW plumbing products will grow as US consumers continue to opt for low-cost plastic pipe and fittings.
