Find the original specification
Locate the relevant contract attachment, finish schedule or confirmed upgrade order. Identify the original brand, model, dimensions or functional description where available. A show-home memory can prompt a question, but connect it to written information. Confirm exactly which unit and area the proposal concerns.
Compare old and new side by side
Request the original item, replacement, reason and installation timing. Focus on dimensions, function, appearance, maintenance and warranty rather than brand reputation alone. A sample or product sheet may help. “Upgrade” and “equivalent” should be explained in terms you can assess.
Describe a concrete concern
For example, will the new dimensions conflict with planned cabinetry? Does the colour differ from selected finishes? Are replacement parts available? Linking your concern to an actual effect makes alternatives easier to discuss. Whether consent is required and how a change should be documented depends on the agreement; a verbal sales explanation is not necessarily a completed contractual amendment.
Retain the confirmed outcome
Save the agreed item, unit reference and confirmation date. Mark undecided matters as outstanding. At inspection, compare the installed product against that record. This guide offers a checking method; it does not suggest that all substitutions are permitted or that every change automatically entitles a buyer to a refund or compensation.
