Raw Material Price Increases to Boost Behind-the-Wall

2 min read

CLEVELAND, June 1, 2022 /PRNewswire/ — The size of the US behind-the-wall plumbing industry skyrocketed in 2021, due primarily to spikes in the costs of many raw materials integral to production, a new Freedonia Group analysis finds. Some of the largest of these increases were seen in HDPE, PVC, and copper pipe:

  • PVC and HDPE price increases were fueled by a residential construction spending boom, as PVC is used in a wide variety of home construction products. Winter storms hitting a major PVC resin supplier in February 2021 further exacerbated shortages and pushed prices upward.
  • Spiking copper pipe prices were caused by a general increase in demand for copper, as well as other factors such as tariffs and mining closures related to COVID-19 safety concerns.

Value demand changes in 2022 and 2023 are also anticipated to be heavily impacted by material pricing, finds a new Freedonia Group analysis. While labor shortages and supply chain issues are expected to remain an issue through 2022 – keeping raw material costs unusually high – prices are projected to start coming back down in 2023. This will lead to a drop in the value of the behind-the-wall plumbing market in that year, despite a sustained increase in sales of pipe in volume terms.

Behind-the-Wall Plumbing Product Market to Top $15 Billion in 2025

The Freedonia Group projects demand for behind-the-wall plumbing products to advance 8.1% annually to $17.9 billion in 2025. Gains will be boosted by such factors as:

  • design trends toward more and larger bathrooms and larger kitchens
  • above-average increases in single-family housing completions in the first part of the forecast period
  • continued homeowner interest in kitchen and bathroom renovation projects
  • a rebound – beginning in 2022 – in the construction of such commercial structures as office buildings, medical facilities, and educational institutions, which often have extensive fire suppression systems and multiple bathrooms
