## The options, and what each one does

Walk In Tub is sold as one product and behaves as several. The table separates them by what they are made of and where they fit.

 |  | Option | What it is | Where it fits

 | Acrylic | Vacuum-formed sheet | Most common, repairable

 | Fibreglass | Spray-up | Cheaper, flexes

 | Gelcoat | Resin finish | Budget, chips

 | Combo tub-shower | Seated with shower | Best for transfers

 | Shower conversion | Curbless or low curb | Alternative to a tub

## How the choice is made

The decision order is the same in every project: diagnose the problem, set the budget, then pick the material. Buyers who start with the material usually re-do the job. A contractor who quotes a method before inspecting the site is guessing.

## What we check before recommending a method

- Does the material match the exposure — sun, salt, freeze-thaw, water?

- Is the substrate or structure adequate for it?

- Does the warranty cover the failure mode that actually happens?

- Is the maintenance schedule realistic for the owner?

The [cost hub](/cost/) carries the installed ranges, and the [comparison hub](/compare/) puts the two closest options side by side.

### Which option lasts longest?

It depends on exposure more than on brand. The premium material installed badly fails before the mid-range material installed properly.

### Can I change method later?

Sometimes, at a cost. Ask what the removal and disposal line would be before choosing the cheaper option now.
