A distributor’s spare-parts stock should reflect the products in service, customer demand, replenishment conditions and the cost of holding each item. A generic ranking or fixed lead-time rule can miss a part that stops a project or keep stock that no longer fits the installed range.
Key Takeaways
- Start with the models sold, installed and actively supported by the distributor.
- Use orders, service requests, returns and project commitments to estimate demand.
- Review part criticality, confirmed replenishment time, substitutions and obsolescence risk.
- Set stock rules by item group and document the assumptions behind them.
- Revisit the range when supplier, product revision or customer demand changes.
Build the Supported Product List
List the shower hardware models and installations the distributor supports. Map each model to compatible rollers, seals, gaskets, fasteners, covers and other service parts using approved drawings or supplier records. Record fit limits and superseded parts so a similar-looking component is not treated as a replacement without evidence.
Separate parts that are commonly ordered together from items that serve a specific model or project. Keep customer commitments and active warranty or service obligations visible when planning stock.
Set Stock Priorities from Evidence
| Input | How it informs the decision |
|---|---|
| Order and service history | Shows observed requests by part and customer group |
| Part criticality | Shows the consequence if an item is unavailable |
| Supplier replenishment | Uses confirmed lead-time and minimum-order information |
| Substitution status | Identifies whether an approved alternative exists |
| Obsolescence | Flags products or parts approaching a supplier change |
Use a reorder trigger based on expected use during the confirmed replenishment period plus a buffer the distributor chooses for its service target. Keep the source data and review date. Do not use an example lead time from another product or supplier as a rule for every part.
Review Slow-Moving and Changed Parts
Track issues and returns by SKU, model and reason. Review parts with little movement against open projects, installed products and supplier availability before removing them. If a part is replaced or discontinued, verify the cross-reference and inform staff about fit limits and remaining stock.
Ask suppliers to provide updated part lists and notice of product changes as part of the purchasing process. For a broader supplier information checklist, see our wholesale shower hardware RFQ checklist.
Frequently Asked Questions
Which shower hardware spare parts should a distributor stock?
Prioritize parts based on supported models, observed demand, project and service commitments, replenishment conditions and the consequence of a stockout.
Should every replacement part use the same stock rule?
No. Demand, criticality, supplier terms and substitution options differ by part. Document the policy used for each item group.
How should a distributor treat a discontinued part?
Check the affected models, approved replacement, remaining inventory and customer obligations before removing it from the stock list.
When should spare-parts stock be reviewed?
Review it when demand, supplier lead time, product revision, source or supported customer range changes, and on the distributor’s regular inventory review cycle.
