Create one current fixture schedule
For each fixture, record room, purpose, manufacturer, exact model, finish, associated parts and selection status. Mark alternatives as alternatives rather than mixing them into the approved list. A product family name is often insufficient when different models have different installation requirements. Give the current schedule and manufacturer information to the contractor and other affected trades.
Use dates or versions so a later purchase can be traced back to the approved selection. Decide who maintains the schedule and who confirms substitutions. An outdated quotation should not remain the source of truth after a product changes. Include water-using appliances and accessories that affect connections, rather than limit the schedule to the objects visible in the finished room.
Check the complete assembly
Ask the supplier and contractor to confirm the parts needed for the intended arrangement. A trim set, concealed valve, mounting system or drain accessory may be sold separately. Similar appearance does not establish compatibility. Identify who supplies each part and whether the contractor’s quotation includes the selected assembly or a different allowance.
Read the actual product information for dimensional and installation coordination. Do not choose pipe sizes or approve connection designs from a retail specification alone. Some products may affect backflow protection or other system requirements; the qualified contractor should review those implications. An unfamiliar accessory should be disclosed before purchase rather than added as a casual change after rough-in.
Coordinate dimensions with the finished space
Review the product against the completed wall, floor, countertop or cabinet arrangement. Basin depth, fixture mounting and service access can matter as much as visible width. Give the contractor enough information to establish its coordination requirements, and ask the responsible builder or designer to resolve conflicts with framing or finishes.
Consider everyday access and maintenance as practical selection questions. A beautiful arrangement that conceals a needed service point can create later difficulty. The contractor should identify relevant access; the owner should not infer it from an editorial rendering. Keep manufacturer installation requirements with the room drawings and review both whenever a finish build-up or cabinet position changes.
Set purchasing and delivery responsibilities
Name who buys, checks, stores and delivers each item. Confirm which selection deadlines affect rough-in and which affect final installation. An owner-supplied fixture can reduce control over procurement without reducing the need for coordination. Agree what happens when the item arrives damaged, incomplete or incompatible, including possible additional attendance.
Keep delivery status separate from technical approval. A product arriving on site does not establish that it suits the planned installation. Have substitutions reviewed before accepting them from a supplier. Record the approved substitute, accessories and effects on other work. This prevents a stock shortage from becoming an undocumented instruction to revise pipe locations or alter the room.
Use actual prices and clear allowances
Record the quoted product price and the installation scope separately. If a contractor carries an allowance, ask what it covers and how the actual selected price replaces it. Identify taxes, accessories, delivery and labour responsibilities without assuming every low retail price produces a low installed total. The budget ledger should use your supplied amounts, not invented job ranges.
Request written approval for selection changes that affect scope, price or programme. Alberta’s contractor guidance supports written contracts and approved changes. A selection record should show both the commercial decision and the contractor’s coordination review, while leaving technical compliance to the responsible qualified parties and authority.
Retain the exact installed product information
At completion, update the schedule to the products actually installed. Save manuals, invoices, warranty terms and relevant inspection results. Ask the contractor to identify any substitutions or outstanding components. A box photograph or showroom quotation can help, but it should not replace the actual model record for later servicing.
Follow the manufacturer’s maintenance information and the handover explanation for the installed arrangement. Record accessible controls and service points without presenting them as instructions for dismantling equipment. If a future symptom appears, the model and installation history help a qualified reviewer identify the right scope. Keep product warranty, labour commitment and future service arrangements distinct.
Keep proposed alternatives out of the approved schedule until the responsible review and commercial decision are complete; a convenient availability substitution can affect several trades.
Questions people ask
Is the fixture’s retail price the installed price?
No. Installation, accessories, access, alterations, permits and other work may be separate. Compare the actual complete written scope rather than a retail figure alone.
Can I substitute a similar-looking model?
Have the actual dimensions, connections, compatible parts and installation effects reviewed first. Similar style does not establish an equivalent installation.
Who checks that all required parts arrive?
Assign that responsibility in the purchase and installation agreement, especially for owner-supplied products. Agree the response to missing or damaged parts before work starts.
What information matters for future service?
The exact installed model, associated components, manuals, installation record and warranty contacts. Keep the approved and actual schedules aligned.
