## Symptoms first, quotes second

Most expensive walk in tub mistakes start with a symptom described to a salesperson. The table maps the common symptoms to their usual cause — the diagnosis a contractor should confirm before quoting.

 |  | Symptom | Usual cause

 | Door seal leaks | Wear or misalignment

 | Slow drain | Gravity drain, low head

 | Tub too tall to step over | Measure the sill

 | Water left in the lines | Blow-out not done

 | Installation without permit | Electrical and plumbing code

## What to document

- Photographs with something for scale, taken at the same angle over time.

- Dates: when it started, whether it changes with weather.

- Water: where it goes, where it pools, what it damages.

- Previous work: who did it, when, and with what material.

## What not to do first

Do not accept a repair scope before the cause is named. Patching a symptom is how the same problem returns next season with a bigger invoice. The [methods hub](/methods/) explains what each fix addresses; the [cost hub](/cost/) shows what it should cost.

### When is it an emergency?

When water is entering the structure, when something is structurally unstable, or when a safety system has failed. Everything else can wait for a second opinion.

### Should I get an independent inspection?

For anything structural or over about $5,000, yes. A few hundred dollars for an independent report is cheaper than a wrong scope.
