How this calculator works

The numeric result comes from the bathroom-size table published by This Old House. Ramefor resolves the selected scenario by its registered source and value identifiers.

It does not multiply square feet by a rate, interpolate between size bands, combine publishers, or add location, plumbing, labor, permit, or quality multipliers.

The published range can become less representative when a project moves plumbing, includes premium or custom work, or uncovers concealed damage. Those factors are shown as warnings rather than invented surcharges.
