Showers4Less Publishes Rough-In Guidance for Contractors Quoting Accessible Shower Installations

Most accessible shower change orders trace back to something that could have been measured before the quote went out.

DENVER, Colorado — September 2, 2026

Showers4Less has published rough-in and specification guidance aimed at contractors quoting barrier-free and accessible shower installations.

The company says the guidance came from reviewing why accessible shower projects generate more change orders than conventional bathroom work. In most cases the answer is something that could have been established before the quote went out.

What to establish before quoting

• Floor construction. Wood-framed or slab-on-grade determines whether a true zero threshold is achievable and what it costs. This single question drives more variance than anything else on the job.
• Existing drain location and type. Moving a drain is routine work and it is not free. Whether it is needed changes the number materially.
• Joist direction and depth where a recessed pan is planned.
• Doorway width, if the client's access requirement involves a walker or wheelchair. A perfect shower behind a 24-inch door solves nothing.
• Blocking for grab bars, which is trivial while the wall is open and expensive afterward.
• Valve height and type, which differs for seated use.

The pan and wall system question

The company repeats guidance it considers non-negotiable: pans and wall systems should come from the same manufacturer as a matched set. The pan-to-wall joint is the most likely point of failure and the most expensive place to discover one, and mixing components across manufacturers is the most reliable way to create a problem there.

On the conversation with the client

The company notes that accessible bathroom work frequently involves a client under time pressure — a hospital discharge, a declining parent — and that setting realistic expectations about structural constraints early is easier than revising a number later.
