Create one row for each connected group of products, then list every included and excluded part. Manufacturer-tested combinations are useful references for those exact models; visual similarity alone cannot establish compatibility for a different set.
| Record | What to make explicit |
|---|---|
| Basin and tap | Compare mounting type, tap-hole arrangement and the proposed spout position using both product drawings. |
| Basin and waste | Ask for the matching waste specification, whether the basin has an overflow, and which connection parts are supplied. |
| Concealed shower parts | List the concealed body and visible trim by exact model. Request written compatibility confirmation rather than a matching-finish assumption. |
| Toilet assembly | Separate the pan, tank or carrier, seat, controls and fixing parts. Mark what is included and what the installer must source. |
| Quote comparison | Compare the same complete package across quotations. Leave excluded parts visible so a lower headline price does not hide missing scope. |
Take this into your next conversation.
- Record exact model codes for connected products.
- Separate supplied parts from locally sourced parts.
- Keep compatibility answers with the product schedule.
- Recheck the whole group when one product changes.
